Title: Photo printing system and camera for the same

Description:
BACKGROUND OF THE INVENTION  
       [0001] 1. Field of the Invention  
       [0002] This invention relates to a photo printing system, wherein an image of a field angle different from the field angle of an image, which has been recorded on photographic film with a photographing operation, is capable of being printed. This invention also relates to a photo printing system, wherein a photograph, which has been taken under incorrect conditions of light distribution characteristics and/or a light throw distance of a strobe, is capable of being printed as if it were taken with a correct exposure. This invention further relates to a camera for use in the photo printing system. This invention still further relates to a zoom finder constituted such that the field angle of a displayed image can be altered continuously.  
       [0003] 2. Description of the Prior Art  
       [0004] Photo printing systems, wherein an enlargement magnification ratio in a printing process is adjusted, and an image of a field angle different from the field angle of an image, which has been recorded on photographic film with a photographing operation, is thereby printed, have heretofore been proposed. One example of such photo printing systems is disclosed in Japanese Patent Publication No. 5(1993)-82921. It is necessary for cameras corresponding to such photo printing systems to be formed such that the field angle of a printed photograph can be specified, such that the photographer can confirm the specified field angle, and such that the printing process in a processing laboratory, or the like, can be notified of the specified field angle.  
       [0005] One example of a pseudo zoom camera formed in the manner described above is disclosed in Japanese Patent Publication No. 5(1993)-82921. The disclosed pseudo zoom camera has a structure such that a zoom ring of a zoom taking lens can be moved to a region beyond a tele-side limit or a wide-angle side limit of the lens itself, such that part of the visual field within a finder may be limited by a masking unit and a printing range is thereby displayed when the zoom ring has been moved to such a region, and such that information, which represents what masking state was set when the photograph was taken, may be optically recorded in an area outside of an image recording region on the film.  
       [0006] With the pseudo zoom camera having the structure described above, in the pseudo zoom region, the size of the image displayed in the finder is invariable. Therefore, in cases where the pseudo zoom camera having the structure described above is used, the problems are encountered in that it is difficult for the photographer to intuitively ascertain an image of a print obtained from pseudo zoom functions.  
       [0007] For example, in the pseudo zoom region on the tele-side, as the zoom magnification ratio is set to be high, the masking range becomes broad and the visual field in the finder becomes narrow. However, a photographer, or the like, who is inexperienced in pseudo zoom cameras, cannot easily imagine that a print, in which such a narrow range has been enlarged to a predetermined size, is obtained, and he will intuitively feel that a print, in which a peripheral blank area is broad and an image-recording range is limited to a narrow area, is obtained.  
       SUMMARY OF THE INVENTION  
       [0008] The primary object of the present invention is to provide a pseudo zoom camera, which is capable of indicating an image reproduction range on a print obtained from pseudo zoom functions such that a photographer can easily ascertain the image reproduction range.  
       [0009] Another object of the present invention is to provide a photo printing system, wherein a photoprint of the same field angle as that indicated by a finder of the pseudo zoom camera is capable of being obtained from a film cartridge, which has been used in the pseudo zoom camera.  
       [0010] A further object of the present invention is to provide a pseudo zoom camera, wherein magnification ratios, which are required of a taking zoom lens and a tele-conversion lens such that a zoom magnification ratio of a print obtained from pseudo zoom functions may be kept high, are kept to be comparatively low, and the camera is thereby kept small in size and cheap in cost.  
       [0011] A still further object of the present invention is to provide a photo printing system, wherein a photographic image having been recorded on photographic film with the pseudo zoom camera, in which the magnification ratios required of the taking zoom lens and the tele-conversion lens are kept to be comparatively low, is printed as an image of a field angle different from the field angle of the photographic image, which has been recorded on the photographic film.  
       [0012] Another object of the present invention is to provide a photo printing system, wherein a photograph, which has been taken under incorrect conditions of light distribution characteristics and/or a light throw distance of a strobe, is capable of being printed as if it were taken with a correct exposure.  
       [0013] A further object of the present invention is to provide a camera, with which a photographer is capable of taking a photograph by arbitrarily altering the light distribution characteristics and/or the light throw distance of the strobe on the assumption that an incorrect exposure will be compensated for by the photo printing system.  
       [0014] A still further object of the present invention is to provide a zoom finder wherein, even if a zoom ratio is set to be high, various aberrations are capable of being kept to be low, and wherein the overall length of the finder is capable of being kept to be comparatively short.  
       [0015] The present invention provides a first pseudo zoom camera, which utilizes a film cartridge provided with an information storing means, the pseudo zoom camera comprising:  
       [0016] i) a taking lens optical system for projecting an object image onto a portion of photographic film, which portion has been pulled out of the film cartridge,

       [0019] In the first pseudo zoom camera in accordance with the present invention, by way of example, the finder optical system may comprise:

       [0023] Also, the fundamental optical system of the finder optical system and the taking lens optical system should preferably be zoom optical systems, which are interlocked with each other at least in a partial region.  
       [0024] In cases where the zoom optical systems interlocked with each other are employed, the pseudo zoom camera should preferably further comprise a lens driving means, which combines a predetermined conversion lens with the fundamental optical system of the finder optical system when a zooming position of the taking lens optical system has been set at a predetermined position.  
       [0025] In cases where the lens driving means described above is provided and a conversion lens is automatically combined with the fundamental optical system of the finder optical system, the pseudo zoom camera should preferably further comprise means for carrying out a zooming operation of the fundamental optical system of the finder optical system when a state of combination of the fundamental optical system and a conversion lens with each other (i.e., whether a conversion lens is or is not combined with the fundamental optical system, or the kind of the conversion lens combined with the fundamental optical system) is changed over, the zooming operation of the fundamental optical system being carried out such that a magnification ratio of the entire finder optical system before the change-over is carried out and the magnification ratio of the entire finder optical system after the change-over is carried out may become approximately identical with each other.  
       [0026] In cases where the fundamental optical system of the finder optical system and the taking lens optical system are constituted as the zoom optical systems, which are interlocked with each other, the pseudo zoom camera may further comprise a pseudo zoom operation switch, which is to be operated by a photographer, and a lens driving means, which combines a predetermined conversion lens with the fundamental optical system of the finder optical system in accordance with the operation of the pseudo zoom operation switch.

       [0033] In the first photo printing system in accordance with the present invention, the printing means should preferably comprise:  
       [0034] a) a film image read-out means for reading out a film image formed on the photographic film, which has been subjected to the development processing, and thereby obtaining an image signal representing the film image,  
       [0035] b) a printed image output means for reproducing the film image on the recording material from the image signal, and  
       [0036] c) a signal processing means for carrying out signal processing on the image signal, and thereby altering a printed image output magnification ratio in the printed image output means.  
       [0037] Alternatively, the printing means may comprise:  
       [0038] a) a film support means for supporting the photographic film, which has been subjected to the development processing,  
       [0039] b) a projection optical system for projecting a film image, which has been formed on the photographic film, onto a photosensitive recording material, and  
       [0040] c) means for changing relationship between positions of at least two among the projection optical system, the film support means, and the photosensitive recording material, and thereby altering a projection magnification ratio of the film image.  
       [0041] The present invention further provides a second pseudo zoom camera for use in taking a photograph for obtaining pseudo zoom effects with the maximum zoom magnification ratio of m by changing an enlargement ratio in a printing operation, the pseudo zoom camera comprising:  
       [0042] i) a taking zoom lens for projecting an object image onto photographic film, the taking zoom lens having a zoom magnification ratio of n,  
       [0043] ii) a finder zoom optical system capable of displaying an image of a field angle, which is different from the field angle of the object image formed by the taking zoom lens, in a region representing an image-recording range, the finder zoom optical system having a zoom magnification ratio of p, where n&lt;p&lt;m·n,  
       [0044] iii) a tele-conversion lens, which is releasably combined with the finder zoom optical system, and which alters the field angle of the displayed image in the predetermined region when it is combined with the finder zoom optical system, the tele-conversion lens having a magnification ratio of q, and  
       [0045] iv) a conversion lens driving means, which is to be operated by a photographer, and which locates the tele-conversion lens selectively at a position that combines with the finder zoom optical system or at a position that is released from the finder zoom optical system.  
       [0046] In the second pseudo zoom camera in accordance with the present invention, the magnification ratios should preferably be set such that m·n=p·q.  
       [0047] Also, the second pseudo zoom camera in accordance with the present invention should preferably utilize a film cartridge provided with an information storing means and should preferably further comprise a writing means for writing information representing an image range ratio of the image, which is displayed in the region representing the image-recording range, to the object image, the information being written on the information storing means of the film cartridge.  
       [0048] The present invention still further provides a second photo printing system, wherein a photoprint is obtained from the film cartridge having been used in the second pseudo zoom camera in accordance with the present invention, the photo printing system comprising:  
       [0049] i) a printing means for printing the object image in a predetermined image forming area on a recording material and from the photographic film, which has been subjected to development processing, the printing being carried out such that image size enlargement and reduction scales may be altered,  
       [0050] ii) a reading means for reading the information representing the image range ratio, which information has been written on the information storing means of the film cartridge, and  
       [0051] iii) an image size enlargement and reduction scales control means for setting the image size enlargement scale or the image size reduction scale in the printing operation, which is carried out by the printing means, at a value at which the image of the field angle displayed in the region by the finder zoom optical system is printed in the image forming area such that the entire area of the image displayed in the region may approximately exactly correspond to the entire area of the image forming area, the image size enlargement scale or the image size reduction scale being set in accordance with the information, which has been read by the reading means.  
       [0052] In the second photo printing system in accordance with the present invention, the printing means should preferably comprise:  
       [0053] a) a film image read-out means for reading out a film image formed on the photographic film, which has been subjected to the development processing, and thereby obtaining an image signal representing the film image,  
       [0054] b) a printed image output means for reproducing the film image on the recording material from the image signal, and  
       [0055] c) a signal processing means for carrying out signal processing on the image signal, and thereby altering a printed image output magnification ratio in the printed image output means.  
       [0056] Alternatively, the printing means may comprise:  
       [0057] a) a film support means for supporting the photographic film, which has been subjected to the development processing,  
       [0058] b) a projection optical system for projecting a film image, which has been formed on the photographic film, onto a photosensitive recording material, and  
       [0059] c) means for changing relationship between positions of at least two among the projection optical system, the film support means, and the photosensitive recording material, and thereby altering a projection magnification ratio of the film image.  
       [0060] The present invention also provides a third camera, which utilizes a film cartridge provided with an information storing means, the camera comprising:  
       [0061] i) a light distribution characteristics altering means for altering light distribution characteristics of a strobe, and  
       [0062] ii) a writing means for writing information, which represents the light distribution characteristics with respect to each of frames on photographic film, and information, which represents the corresponding frame number, on the information storing means of the film cartridge.  
       [0063] By way of example, the light distribution characteristics altering means may change positions of a flash tube and a reflector of the strobe relative to the position of an optical panel, which is located in front of the flash tube.  
       [0064] Also, the light distribution characteristics altering means may change relationship between a position of a flash tube of the strobe and a position of a reflector of the strobe. Further, the light distribution characteristics altering means may change characteristics of an optical panel, which is located in front of a flash tube of the strobe. For example, for such purposes, the optical panel may be exchanged with a different one, or a new panel may be added to the optical panel.  
       [0065] Such that the setting of the light distribution characteristics may be carried out easily, the third camera in accordance with the present invention should preferably further comprise:  
       [0066] a taking lens constituted of a zoom optical system,  
       [0067] a plurality of tables, each of which defines the light distribution characteristics with respect to one of a plurality of zooming positions of the taking lens,  
       [0068] a table selecting means for selecting a table from the plurality of the tables, and  
       [0069] a control means for controlling the light distribution characteristics altering means in accordance with the table, which has been selected by the table selecting means, such that the light distribution characteristics according to a zooming position of the taking lens may be obtained.  
       [0070] The present invention further provides a third photo printing system, wherein a photoprint is obtained from the film cartridge having been used in the third camera in accordance with the present invention, the photo printing system comprising:  
       [0071] i) a printing means for printing an object image on a recording material and from the photographic film, which has been subjected to development processing,  
       [0072] ii) a reading means for reading the information representing the light distribution characteristics, which information has been written on the information storing means of the film cartridge, and  
       [0073] iii) a printed image density control means for controlling printed image density, which is formed by the printing means, in accordance with the information, which has been read by the reading means, such that an incorrect exposure may be compensated for with respect to each portion in a surface of the recording material.  
       [0074] In the third photo printing system in accordance with the present invention, the printed image density control means should preferably control the printed image density at a peripheral portion of the recording material, such that insufficiency in brightness of an edge of an image field due to the strobe may be compensated for.  
       [0075] Also, in order for the printed image density to be controlled appropriately with respect to each portion in the surface of the recording material, the third photo printing system in accordance with the present invention should preferably be modified such that the printing means may comprise:  
       [0076] a) a film image read-out means for reading out a film image formed on the photographic: film, which has been subjected to the development processing, and thereby obtaining an image signal representing the film image, and  
       [0077] b) a printed image output means for reproducing the film image on the recording material from the image signal, and  
       [0078] the printed image density control means may carry out signal processing on the image signal and may thereby change the printed image density.  
       [0079] The present invention still further provides a zoom finder, comprising:  
       [0080] i) a zoom optical system, which is formed as a system independent of a taking lens of a camera, and which displays a visual field image in a predetermined region representing an image-recording range, such that a field angle of the visual field image may be altered,  
       [0081] ii) at least one conversion lens, which is releasably combined with the zoom optical system, and which alters the field angle of the displayed image in the predetermined region when it is combined with the zoom optical system, and  
       [0082] iii) a lens driving means for moving the conversion lens between a position that combines with the zoom optical system and a position that is released from the zoom optical system.  
       [0083] In the zoom finder in accordance with the present invention, in cases where the taking lens is a zoom lens, the lens driving means should preferably be constituted such that, when a zooming position of the taking lens has been set at a predetermined position, the lens driving means may automatically combine a predetermined conversion lens with the zoom optical system.  
       [0084] In cases where a conversion lens is automatically combined with the zoom optical system, the zoom finder should preferably further comprise means for carrying out a zooming operation of the zoom optical system when a state of combination of the zoom optical system and a conversion lens with each other (i.e., whether a conversion lens is or is not combined with the zoom optical system, or the kind of the conversion lens combined with the zoom optical system) is changed over, the zooming operation of the zoom optical system being carried out such that a magnification ratio of the entire finder optical system before the change-over is carried out and the magnification ratio of the entire finder optical system after the change-over is carried out may become approximately identical with each other.  
       [0085] Also, in cases where the taking lens of the camera is the zoom lens, a range of field angle alteration by the zoom optical system and a conversion lens should preferably be set to be wider than the range of field angle alteration by the taking lens.  
       [0086] With the first pseudo zoom camera in accordance with the present invention, the finder optical system is formed such that the image of the field angle, which is different from the field angle of the object image formed by the taking lens optical system, can be displayed in the predetermined region representing the image!-recording range. Also, the information representing the image range ratio of the image, which is displayed in the predetermined region by the finder optical system, to the object image is written on the information storing means of the film cartridge. Therefore, the printing process in a processing laboratory, or the like, which is furnished with the film cartridge, can be notified of in what ratio the range, which has been recognized as the image-recording range by the photographer, differs from the range of the object image having been recorded on the photographic film.  
       [0087] Accordingly, in the first photo printing system in accordance with the present invention, the information representing the image range ratio is read from the information storing means of the film cartridge. Also, in accordance with the thus read information, the image size enlargement scale or the image size reduction scale in the printing operation, which is carried out by the printing means, is set at a value obtained by multiplying the normal value, at which the object image formed by the taking lens optical system is printed in the image forming area of the recording material such that the entire area of the object image may approximately exactly correspond to the entire area of the image forming area, by the image range ratio, which has been read by the reading means. In this manner, a photoprint of the same field angle as that indicated by the finder of the pseudo zoom camera as the image-recording range can be obtained.  
       [0088] Further, with the first pseudo zoom camera in accordance with the present invention, the image of the field angle, which will be printed, is displayed at all times in the predetermined region of the finder. Therefore, the photographer can intuitively and accurately ascertain the field angle of the printed photograph. The feature is advantageous over the conventional technique, wherein the size of the image displayed in the finder is kept the same and the field angle of the image to be printed is adjusted and displayed with the masking operation, or the like.  
       [0089] As described above, the first pseudo zoom camera in accordance with the present invention, wherein the finder optical system comprises the fundamental optical system and at least one conversion lens, may further comprise the lens driving means, which combines a predetermined conversion lens with the fundamental optical system of the finder optical system when a zooming position of the taking lens optical system has been set at a predetermined position. In such cases, it is unnecessary for the photographer to carry out a particular operation for pseudo zoom, and the photographer can thus record the image, which is to be subjected to pseudo zoom processing.  
       [0090] Also, in cases where the lens driving means described above is provided and a conversion lens is automatically combined with the fundamental optical system of the finder optical system, the first pseudo zoom camera in accordance with the present invention may further comprise the means for carrying out a zooming operation of the fundamental optical system of the finder optical system when the state of combination of the fundamental optical system and a conversion lens with each other (i.e., whether a conversion lens is or is not combined with the fundamental optical system, or the kind of the conversion lens combined with the fundamental optical system) is changed over, the zooming operation of the fundamental optical system being carried out such that the magnification ratio of the entire finder optical system before the change-over is carried out and the magnification ratio of the entire finder optical system after the change-over is carried out may become approximately identical with each other. In such cases, the field angle of the image displayed in the finder can be prevented from changing sharply before the change-over is carried out and after the change-over is carried out. Therefore, the photographer can carry out the zooming operation without experiencing a feeling of discomfort.  
       [0091] Further, in cases where the fundamental optical system of the finder optical system and the taking lens optical system are constituted as the zoom optical systems, which are interlocked with each other, the first pseudo zoom camera in accordance with the present invention may further comprise the pseudo zoom operation switch, which is to be operated by the photographer, and the lens driving means, which combines a predetermined conversion lens with the fundamental optical system of the finder optical system in accordance with the operation of the pseudo zoom operation switch. In such cases, the field angle of the image displayed in the finder will change sharply before the pseudo zoom operation switch is operated and after the pseudo zoom operation switch is operated. However, in such cases, since the photographer operates the pseudo zoom operation switch with the intention of changing the photographing field angle to the tele-side or the wide-angle side, he can feel the sharp change in field angle as being natural.  
       [0092] With the first pseudo zoom camera in accordance with the present invention, wherein the taking lens optical system is an optical system having a fixed focal length and the finder optical system is a zoom optical system, the taking lens optical system, which should ordinarily be formed under more severe design conditions from the view point of aberrations, or the like, than in the finder optical system, can be kept comparatively simple in structure and cheap in cost.  
       [0093] In the first pseudo zoom camera in accordance with the present invention, the taking lens optical system and the finder optical system may be constituted of the zoom optical systems, which are interlocked with each other in a partial region, the zoom optical system, which constitutes the finder optical system, having a zoom ratio higher than the zoom ratio of the zoom optical system, which constitutes the taking lens optical system. In such cases, a wide range of the photographing field angle and a wide range of the pseudo zoom field angle can be covered by virtue of the finder optical system, while the taking lens optical system is being kept comparatively simple in structure and cheap in cost as described above.  
       [0094] The optical performance required of the finder optical system is lower than the optical performance required of the taking lens optical system. Therefore, even if the finder optical system having a zoom ratio higher than the zoom ratio of the taking lens optical system is employed, ordinarily, no problem will occur in practice.  
       [0095] The second pseudo zoom camera in accordance with the present invention has the effects described below.  
       [0096] When the taking zoom lens and the finder zoom optical system are compared with each other with respect to the tendency to become large in size and expensive in cost due to an increase in zoom magnification ratio, the taking zoom lens has a higher tendency than the finder zoom optical system. With the second pseudo zoom camera in accordance with the present invention, the zoom magnification ratio, n, of the taking zoom lens, which has a high tendency to become large in size and expensive in cost due to an increase in zoom magnification ratio, is set to be lower than the zoom magnification ratio, p, of the finder zoom optical system. Therefore, the taking zoom lens can be prevented from becoming large in size and expensive in cost due to an increase in zoom magnification ratio, and the pseudo zoom camera can be kept comparatively small in size and cheap in cost.  
       [0097] Also, with the second pseudo zoom camera, wherein the zoom magnification ratio, p, of the finder zoom optical system is higher than the zoom magnification ratio, n, of the taking zoom lens, as the tele-conversion lens, which is apt to become large in size and expensive in cost due to an increase in magnification ratio, a tele-conversion lens having a comparatively low magnification ratio can be employed. Therefore, also with this feature, the second pseudo zoom camera in accordance with the present invention can be kept small in size and cheap in cost.  
       [0098] Particularly, with the second pseudo zoom camera in accordance with the present invention, wherein the magnification ratios are set such that m·n=p·q, the finder zoom optical system can display at most an image of the same field angle as the field angle of the print in the extreme tele-state, which is obtained by combining the zoom effects of the taking zoom lens and the pseudo zoom effects with each other.  
       [0099] The field angle of the image displayed in the finder will change sharply before the conversion lens driving means is operated by the photographer and after the conversion lens driving means is operated by the photographer. However, in such cases, since the photographer operates the conversion lens driving means with the intention of changing the photographing field angle to the tele-side or the wide-angle side, he can feel the sharp change in field angle as being natural.  
       [0100] With the second photo printing system in accordance with the present invention, the same effects as those with the first photo printing system in accordance with the present invention can be obtained.  
       [0101] With the third camera in accordance with the present invention, which is provided with the light distribution characteristics altering means for altering the light distribution characteristics of the strobe, the photographer can take a photograph by arbitrarily altering the light distribution characteristics and/or the light throw distance of the strobe. For example, the photographer can take a photograph by setting the light distribution characteristics of the strobe such that the peripheral light quantity may be low or such that the light throw distance may be short.  
       [0102] Also, with the third camera in accordance with the present invention, the writing means writes the information, which represents the light distribution characteristics with respect to each of frames on the photographic film, and the information, which represents the corresponding frame number, on the information storing means of the film cartridge. Therefore, the printing process can be notified of the light distribution characteristics of the strobe.  
       [0103] With the third photo printing system in accordance with the present invention, the printed image density can be controlled in accordance with the information representing the light distribution characteristics, which has been read from the information storing means of the film cartridge, such that an incorrect exposure may be compensated for with respect to each portion in a surface of the recording material. Therefore, even if the light distribution characteristics and the light throw distance of the strobe, which were set in the photographing operation, were incorrect, a print can be obtained such that it may have correct image density over the entire area of the surface of the recording material.  
       [0104] With the zoom finder in accordance with the present invention, at least one conversion lens is combined with the zoom optical system, and the field angle of the image displayed in the finder is thereby altered. Therefore, even if a zoom optical system having a comparatively low zoom ratio is employed as the zoom optical system, a high zoom ratio can be achieved as a whole. For example, a zoom optical system having a zoom ratio of 3 may be employed, and a tele-conversion lens having a zoom ratio of 2 may be set at the position that is combined with the zoom optical system or at the position that is released from the zoom optical system. In such cases, a zoom ratio of 6 can be achieved by the entire finder.  
       [0105] Since a high zoom ratio can thus be obtained, a zoom optical system having a comparatively low zoom ratio can be employed as the zoom optical system. As a result, various aberrations of the zoom optical system can be kept small, and the zoom length of the zoom optical system can be kept short. Therefore, the zoom finder in accordance with the present invention can be formed such that the aberrations may be small and the overall length may be comparatively short.  
       [0106] In the zoom finder in accordance with the present invention, in cases where the taking lens is a zoom lens, the lens driving means may be constituted such that, when the zooming position of the taking lens has been set at a predetermined position, the lens driving means may automatically combine a predetermined conversion lens with the zoom optical system. In such cases, it is unnecessary for the photographer to carry out an operation for changing over the conversion lens. When the photographer merely carries out the zooming operation of the taking lens for selecting the photographing field angle, a predetermined conversion lens can be automatically combined with the zoom optical system.  
       [0107] In cases where a conversion lens is automatically combined with the zoom optical system, the zoom finder in accordance with the present invention may further comprise the means for carrying out the zooming operation of the zoom optical system when the state of combination of the zoom optical system and a conversion lens with each other (i.e., whether a conversion lens is or is not combined with the zoom optical system, or the kind of the conversion lens combined with the zoom optical system) is changed over, the zooming operation of the zoom optical system being carried out such that the magnification ratio of the entire finder optical system before the change-over is carried out and the magnification ratio of the entire finder optical system after the change-over is carried out may become approximately identical with each other. In such cases, the field angle of the image displayed in the finder can be prevented from changing sharply before the change-over is carried out and after the change-over is carried out. Therefore, the photographer can carry out the zooming operation without experiencing a feeling of discomfort.  
       [0108] Also, in cases where the taking lens of the camera is the zoom lens, the zoom finder in accordance with the present invention may be constituted such that the range of field angle alteration by the zoom optical system and the conversion lens may be set to be wider than the range of field angle alteration by the taking lens. In such cases, when the pseudo zoom technique or an electronic zoom technique is utilized, a visual field image of the field angle, which is beyond the range of field angle alteration by the taking lens and which is the same as the field angle of a print obtained with the pseudo zoom technique or an image formed by the electronic zoom technique, can be displayed in the finder. (The electronic zoom technique is a technique utilized in an electronic still camera or a video camera for detecting an image, which has been formed by a taking lens, with an image sensor, such as a CCD image sensor. With the electronic zoom technique, the field angle of the formed image is altered by thinning out the image signal components;, which represent pixels in the image, or adding new signal components to the image signal components.)

     DESCRIPTION OF THE PREFERRED EMBODIMENTS  
     [0143] The present invention will hereinbelow be described in further detail with reference to the accompanying drawings.  
     [0144]FIG. 1 is a side view showing a finder optical system in a first embodiment of the pseudo zoom camera in accordance with the present invention. FIG. 2 is a perspective view showing the first embodiment of the pseudo zoom camera in accordance with the present invention.  
     [0145] As illustrated in FIG. 2, the pseudo zoom camera is provided with a taking lens  10  constituted of a zoom lens, a finder window  11 , an AE (automatic exposure) light receiving window  12 , an AF (automatic focusing) light projecting window  13 , a strobe flashing section  15 , and the like, which are located at the front surface of a body  1 . Also, a shutter push button  20 , a zoom lever  21 , a pseudo zoom mode push button  22 , and the like, are located at the top surface of the body  1 .  
     [0146] As illustrated in FIG. 1, a finder optical system  30  comprises a fundamental optical system  31  and a conversion lens block  32 .  
     [0147] The fundamental optical system  31  is an ordinary relay type of real image finder optical system, in which the height of the optical path is changed at an intermediate position by mirrors  33  and  34 . The fundamental optical system  31  comprises an objective lens  35 , zoom lenses  36  and  37 , a relay lens  38 , a focal plate  39  on which a finder image is formed, a visual field plate  40  which indicates the range of an image recorded, an eyepiece  41 , and the like.  
     [0148] A wide-conversion lens  42  and a tele-conversion lens  43  are secured to the conversion lens block  32 . By way of example, the wide-conversion lens  42  reduces the finder image, which is formed by the fundamental optical system  31 , to a size 0.7 times as large as the original size. The tele-conversion lens  43  enlarges the finder image to a size 1.4 times as large as the original size.  
     [0149]FIG. 3 is an exploded perspective view showing the major part of the pseudo zoom camera shown in FIG. 2. As illustrated in FIG. 3, the conversion lens block  32  is provided with a rack  44 , which extends vertically. A pinion gear  46 , which is rotated by a lens change-over actuator  45 , is engaged with the rack  44 .  
     [0150]FIG. 4 is a perspective view showing a film cartridge  50 , which is utilized in the pseudo zoom camera shown in FIG. 2. The film cartridge  50  comprises a negative type of photographic film  51  having a comparatively broad width, such as Brownie film, a spool  52 , and a cartridge  53 . The photographic film  51  is wound around the spool  52  and is thereby accommodated in the cartridge  53 . A storage device  54 , which is constituted of an IC memory chip, is secured to a portion of the outer surface of the cartridge  53 .  
     [0151]FIG. 5 is a block diagram showing an electric control constitution in the first embodiment of the pseudo zoom camera. As illustrated in FIG. 5, the electric circuitry of the pseudo zoom camera is provided with a central processing unit (CPU)  60 , which controls fundamental operations of the pseudo zoom camera. The CPU  60  receives signals from a pseudo zoom switch  61  which is operated by the pseudo zoom mode push button  22  described above, a release switch  62 , a zoom switch  63 , a main switch  64 , and a sensor  65 . (The sensor  65  represents a group of various kinds of sensors.)  
     [0152] Also, the CPU  60  is connected to a liquid crystal display device (LCD)  66  which displays various kinds of information in, for example, the finder, a photometric device  67  for determining a correct exposure, an AF circuit  68 , a strobe  69 , and drivers  70 ,  71 ,  72 , and  73 . Each of these devices is controlled by the CPU  60 .  
     [0153] The driver  70  drives a film wind-up motor  74  and a lens driving motor  75 . The driver  71  drives a shutter driving motor  76  and a reflector driving motor  77 , which operates a reflector (i.e., a reflecting plate) for changing light distribution characteristics of the strobe  69 . The driver  72  drives a zoom driving motor  78  and a finder driving motor  79 . The driver  73  drives the lens change-over actuator  45  described above (shown in FIG. 3).  
     [0154] How the first embodiment of the pseudo zoom camera operates will be described hereinbelow. By way of example, the taking lens  10  has a zoom ratio of 3, and the fundamental optical system  31  of the finder optical system  30  has a zoom ratio of 3. In the range of the zoom ratio of 3, alteration of the photographing field angle is carried out in the same manner as that in an ordinary 35 mm lens shutter camera provided with a zoom lens, or the like.  
     [0155] Specifically, when the zoom lever  21  is operated to a tele-side or a wide-side (i.e., a wide-angle side), a tele-operation signal or a wide-operation signal is fed from the zoom switch  63  shown in FIG. 5 into the CPU  60 . The feeding of the tele-operation signal or the wide-operation signal into the CPU  60  is continued until the operation of the zoom lever  21  is stopped.  
     [0156] When the CPU  60  receives the tele-operation signal, it feeds a control signal, which instructs tele-side driving, to the driver  72 . Also, the zoom driving motor  78  and the finder driving motor  79  receive driving current from the driver  72  and rotate in directions that set the focal lengths of the taking lens  10  and the fundamental optical system  31 , respectively, at large values.  
     [0157] When the CPU  60  receives the wide-operation signal, it feeds a control signal, which instructs wide-side driving, to the driver  72 . Also, the zoom driving motor  78  and the finder driving motor  79  receive driving current from the driver  72  and rotate in directions that set the focal lengths of the taking lens  10  and the fundamental optical system  31 , respectively, at small values.  
     [0158] In each of the taking lens  10  and the fundamental optical system  31 , a predetermined number of lenses are moved along the optical axis direction by a known cam mechanism, which receives the rotation force of the corresponding zoom driving motor  78  or the corresponding finder driving motor  79 , and the focal length is thereby changed. In this manner, the field angle of the object image, which is formed by the taking lens  10 , and the field angle of the finder image, which is displayed by the finder optical system  30 , are changed such that the field angles of the object image and the finder image may be kept identical with each other.  
     [0159] When the operation of the zoom lever  21  is stopped, the feeding of the tele-operation signal or the wide-operation signal into the CPU  60  is ceased, and the zoom driving motor  78  and the finder driving motor  79  are stopped. At this time, the taking lens  10  is set in the state, in which an image of a field angle identical with the field angle of the finder image displayed in a visual field frame of the visual field plate  40  is formed on the photographic film  51 . Therefore, when the shutter push button  20  is pushed in this state, predetermined automatic focusing processing and automatic exposure processing are carried out, and a photographic latent image of the aforesaid field angle is recorded on the photographic film  51 .  
     [0160] In FIG. 1, wide-end positions of the zoom lenses  36  and  37  are indicated by the solid lines, and tele-end positions of them are indicated by the broken lines. By way of example, the wide-end positions are such that the magnification ratio of the fundamental optical system  31  may become equal to 0.4, and the tele-end positions are such that the magnification ratio of the fundamental optical system  31  may become equal to 1.2. When the zoom lenses  36  and  37  take the tele-end positions, the taking lens  10  is also set in the corresponding state, in which the focal length is longest. Also, when the zoom lenses  36  and  37  take the wide-end positions, the taking lens  10  is also set in the corresponding state, in which the focal length is shortest.  
     [0161] As described above, the finder optical system  30  is constituted of the fundamental optical system  31  and the conversion lens block  32 . Either one of the wide-conversion lens  42  and the tele-conversion lens  43  is selectively combined with the fundamental optical system  31 . The selection of the wide-conversion lens  42  or the tele-conversion lens  43  is carried out by the lens change-over actuator  45 , which is operated in accordance with the state of signal input from a sensor, which detects the zooming positions of the zoom lenses  36  and  37 , and the zoom switch  63  into the CPU  60 . How such an operation is carried out will hereinbelow be described in detail with reference to FIG. 6.  
     [0162] In cases where the aforesaid sensor detects that the zooming positions of the zoom lenses  36  and  37  have not reached the tele-end positions, the CPU  60  controls the lens change-over actuator  45  via the driver  73 , such that the wide-conversion lens  42  having a magnification ratio of 0.7 may be combined with the fundamental optical system  31 .  
     [0163] In this state, the zoom lever  21  may be operated, and the finder driving motor  79  may be actuated during the operation of the zoom lever  21 . In such cases, the magnification ratio of the fundamental optical system  31  takes a value falling within the range, which is indicated by a line segment “a” in FIG. 6, i.e. a value falling within the range of 0.4 to 1.2. Therefore, the finder magnification ratio takes a value falling within the range of 0.28 to 0.84, the values being the products of the magnification ratios of the fundamental optical system  31  and 0.7. (The term “finder magnification ratio” as used herein means the magnification ratio of the combination of the fundamental optical system  31  and the wide-conversion lens  42  or the tele-conversion lens  43  with each other.) As described above, the zooming operation of the taking lens  10  is interlocked with the zooming operation of the fundamental optical system  31 , and the photographing field angle with the taking lens  10  becomes identical with the field angle of the finder image, which is formed in a finder magnification ratio falling within the range of 0.28 to 0.84.  
     [0164] In cases where the aforesaid sensor detects that the zooming positions of the zoom lenses  36  and  37  (and the zooming position of the taking lens  10 ) have reached the tele-end positions, the CPU  60  operates the lens change-over actuator  45  via the driver  73 , such that the conversion lens block  32  may be set in the state, in which the tele-conversion lens  43  having a magnification ratio of 1.4 is combined with the fundamental optical system  31 . Also, the CPU  60  operates the finder driving motor  79  via the driver  72 , such that the magnification ratio of the fundamental optical system  31  may decrease to 0.6 as indicated by a line segment “b” in FIG. 6.  
     [0165] In this state, the finder magnification ratio is 0.6×1.4=0.84, and is the same as the finder magnification ratio before the conversion lens block  32  is moved for the change-over. However, in the intermediate stage of the change-over and the zooming operation of the fundamental optical system  31 , the finder magnification ratio will sharply become high and will thereafter become low little by little. The unnatural finder image, which changes in such a manner, will often confuse the photographer. Therefore, the pseudo zoom camera should preferably be provided with an appropriate blackout means for preventing the finder image from being seen during the period in which a change in magnification ratio occurs.  
     [0166] In cases where the zoom lever  21  is operated to the tele-side even further after the zooming positions of the zoom lenses  36  and  37  have reached the tele-end positions and the tele-operation signal is fed from the zoom switch  63  into the CPU  60 , the CPU  60  operates the finder driving motor  79  such that the magnification ratio of the fundamental optical system  31  may become high (i.e., such that the focal length of the fundamental optical system  31  may become long).  
     [0167] Therefore, in this case, as indicated by a line segment “c” in FIG. 6, the magnification ratio of the fundamental optical system  31  takes a value falling within the range of 0.6 to 1.2. Also, the finder magnification ratio takes a value falling within the range of 0.84 to 1.68, the values being the products of the magnification ratios of the fundamental optical system  31  and 1.4. Even if the finder magnification ratio changes in this manner, since the taking lens  10  is kept at the tele-end position, the field angle of the image photographed at this time is kept the same as the field angle of the finder image, which is displayed in a finder magnification ratio of 0.84.  
     [0168] Each time the shutter push button  20  is pushed and an object image, which is formed by the taking lens  10 , is recorded on the photographic film  51 , in the region indicated by the line segment “c,” the CPU  60  writes information, which represents the image range ratio of the image displayed in the finder to the object image, and information, which represents the frame number of the frame that records the object image, on the storage device  54  of the cartridge  53 . The writing of the information may be carried out with a contact technique via a contact point or with a non-contact technique.  
     [0169] In this embodiment, the finder magnification ratio in this region is equal to (0.84/0.6 )A, wherein A represents the magnification ratio of the fundamental optical system  31 . Also, the field angle of the object image is equal to the field angle of the image displayed in the finder. Therefore, the field angle ratio is equal to A/0.6.  
     [0170] The magnification ratio A of the fundamental optical system  31  can be calculated by utilizing the driving control signal for the finder driving motor  79 , a rotation angle detection signal, which is fed out by an encoder coupled with a rotation shaft of the finder driving motor  79 , output signals, which are obtained from sensors for detecting the positions of the zoom lenses  36  and  37  of the fundamental optical system  31 , or the like.  
     [0171] Thereafter, in accordance with the output signals obtained from the sensors for detecting the positions of the zoom lenses  36  and  37 , or the like, the CPU  60  may detects that the fundamental optical system  31  has been operated toward the wide-side until the magnification ratio A becomes equal to 0.6. In such cases, the CPU  60  operates the lens change-over actuator  45  via the driver  73  and sets the conversion lens block  32  such that the wide-conversion lens  42  having a magnification ratio of 0.7 may be combined with the fundamental optical system  31 .  
     [0172] Also, the CPU  60  operates the finder driving motor  79  via the driver  72  and sets the magnification ratio of the fundamental optical system  31  at the highest value of 1.2 so as to follow the line segment “b” shown in FIG. 6 reversely to the direction in the aforesaid cases. In this state, the finder magnification ratio is equal to 1.2×0.7=0.84 and is thus identical with the value before the conversion lens block  32  is moved for the change-over.  
     [0173] In cases where the zoom lever  21  is operated to the wide-side even further and the wide-operation signal is fed from the zoom switch  63  into the CPU  60 , the CPU  60  operates the finder driving motor  79  such that the magnification ratio of the fundamental optical system  31  may become low (i.e., such that the focal length of the fundamental optical system  31  may become short). Also, after the wide-conversion lens  42  has been combined with the fundamental optical system  31  in the manner described above, the CPU  60  operates the zoom driving motor  78  in the manner interlocked with the finder driving motor  79 , such that an object image may be recorded in the manner described above in the region indicated by the line segment “a” in FIG. 6. Specifically, in this region, the taking lens  10  is also subjected to the zooming operation, and the object image of the same field angle as the field angle of the image displayed in the finder is recorded on the photographic film  51 .  
     [0174] In the region indicated by the line segment “a” in FIG. 6, the image range ratio of the image displayed in the finder to the object image is automatically taken as “1” and is written no the storage device  54 .  
     [0175] After object images have been recorded in the frames of the photographic film  51  accommodated in the film cartridge  50 , the film cartridge  50  is taken out of the camera body  1  and subjected to the development processing in a processing laboratory, or the like. In this manner, the photographic latent images having been recorded on the photographic film  51  are developed. From the thus formed negative film, photoprints are formed on predetermined recording paper. At this time, pseudo zoom processing is carried out in accordance with the information, which has been stored in the storage device  54 . How the pseudo zoom processing is carried out will hereinbelow be described in detail.  
     [0176]FIG. 7 is a schematic view showing an embodiment of the photo printing system in accordance with the present invention. As illustrated in FIG. 7, the photo printing system comprises an image processing apparatus  101  and a photo printer  102 , which is connected to the image processing apparatus  101 .  
     [0177] In this embodiment of the photo printing system, the image processing apparatus  101  is constituted of a general-purpose personal computer, in which special-purpose programs have been incorporated. Also, the image processing apparatus  101  is provided with peripheral equipments, such as a film scanner, which reads out the images from photographic film  51 A having been subjected to the development processing, and a reading means  103 , which reads the information having been stored in the storage device  54  of the cartridge  53  (shown in FIG. 4) that has accommodated the photographic film  51 A. The image processing apparatus  101  is further provided with a media drive unit, such as CD-R or Zip, as an internal or external unit. The image processing apparatus  101  is still further provided with communication equipments (not shown) for transfer of image signals with other computers via a network  104 .  
     [0178] The photo printer  102  may be constituted of a known digital photo printer. The photo printer  102  receives an image signal and output instruction information (representing the number of prints to be formed, the print size, and the like) from the image processing apparatus  101  and carries out a printing operation in accordance with the received image signal and received output instruction information.  
     [0179] In the photo printing system described above, the image processing apparatus  101  carries out predetermined image processing on the image signal, which has been detected from the developed photographic film  51 A, and transfers the processed image signal to the photo printer  102 . Also, the image processing apparatus  101  records the processed image signal on media  106 , such as CD-R. Further, the image processing apparatus  101  receives storage information H, which has been stored in the storage device  54  and has been read by the reading means  103 , from the reading means  103 .  
     [0180] The system constitution of the photo printing system will hereinbelow be described in detail with reference to FIG. 8. In the constitution shown in FIG. 8, functions concerning the image processing may be provided as the functions of the image processing apparatus  101 , or may be incorporated as the functions of the photo printer  102  or the film scanner. Therefore, the constitution shown in FIG. 8 will be described hereinbelow without the correspondence with FIG. 7 being manifested.  
     [0181] As illustrated in FIG. 8, a scanner  110  detects an image signal from the photographic image. The image signal is processed by various image processing means  111  through  116  and is then used in the photo printer  102  for reproducing a photoprint.  
     [0182] A set-up gradation/color processing means  111  automatically makes a judgment as to under-exposure or over-exposure and makes a correction to an appropriate value. An image size enlargement or reduction processing means  112  converts pixel density for matching the size of the printed image to the width of a recording material (e.g., a roll of printing paper) or for carrying out the pseudo zoom processing. A shutting light processing means  113  carries out processing with a shutting light technique described in, for example, Japanese Unexamined Patent Publication No. 9 (1997)-18704. A graininess suppression type of sharpness enhancement processing means  114  carries out a graininess suppression type of sharpness enhancement processing described in, for example, Japanese Unexamined Patent Publication No. 9 (1997)-22460.  
     [0183] Further, besides a series of image processing described above, color conversion in accordance with characteristics of the printer is carried out on the image signal for print reproduction by a 3D conversion processing means  115  or  116 . The 3D conversion processing varies in accordance with whether the film from which the image signal was obtained is negative film or reversal film.  
     [0184] How the pixel density conversion for the pseudo zoom processing is carried out by the image size enlargement or reduction processing means  112  will be described hereinbelow. The image size enlargement or reduction processing means  112  receives the storage information H of each of frames of the photographic film  51 A from the reading means  103 . As described above, the storage information H represents an image range ratio R of the image displayed in the finder to the object image.  
     [0185] In the region indicated by the line segment “a” in FIG. 6, the image range ratio R is “1” at all times. With respect to the frame associated with the image range ratio of “1,” the image size enlargement or reduction processing means  112  does not carry out the pixel density conversion processing for the image size enlargement or reduction. Specifically, in such cases, printing processing is carried out such that an image shown in FIG. 9A, which has been recorded in a certain frame F on the developed photographic film  51 A, may be reproduced on a recording material  200  having a predetermined size as shown in FIG. 9B, such that the image size may not be enlarged or reduced. In this manner, in such cases, a print, on which an image of the same field angle as the field angle of the image displayed in the finder has been recorded, is obtained.  
     [0186] In the region indicated by the line segment “c” in FIG. 6, the image range ratio R, which is represented by the storage information H, takes a value falling within the range of 1 to 2. With respect to the frame associated with the image range ratio taking such a value, the image size enlargement or reduction processing means  112  carries out the image size enlargement processing on the image signal, which has been detected by the scanner  110 , such that, for example, the center point of the photographic image may not be shifted, and such that only a range of 1/R in horizontal and vertical directions may be reproduced on the recording material  200  having a predetermined size. Specifically, in such cases, printing processing is carried out such that, of an image shown in FIG. 9A, which has been recorded in a certain frame F on the developed photographic film  51 A, only the region surrounded by the double-dot chained lines shown in FIG. 9A may be reproduced on the recording material  200  as shown in FIG. 9C.  
     [0187] As described above, in the region indicated by the line segment “c” in FIG. 6, the finder magnification ratio takes a value falling within the range of 0.84 to 1.68. In such cases, the field angle of the object image is kept the same as the field angle of the finder image, which is displayed in a finder magnification ratio of 0.84. However, in such cases, since the image size enlargement processing is carried out in the manner described above, a print, on which an image of the same field angle as the field angle of the image displayed in the finder has been recorded, is obtained.  
     [0188] As described above, with the first embodiment of the pseudo zoom camera and this embodiment of the photo printing system in accordance with the present invention, even if the taking lens  10  having a zoom ratio of 3 is employed, a photoprint can be obtained as if it were photographed with a taking lens having a zoom ratio of 6.  
     [0189] In the first embodiment of the pseudo zoom camera in accordance with the present invention, in cases where a zoom lens is employed as the taking lens, the zoom ratio of the zoom lens is not limited to 3. Also, the taking lens is not limited to the zoom lens, and a lens having a fixed focal length may be utilized as the taking lens.  
     [0190] In cases where the conversion lens is utilized, its magnification ratio is not limited to 0.7 or 1.4 as in the embodiment described above. Also, the number of the conversion lenses is not limited to two. Further, in cases where the conversion lens is utilized, a mode, in which the object image is recorded without a conversion lens being combined with the fundamental optical system  31  of the finder optical system  30 , may also be set.  
     [0191] Also, the way, in which the wide-conversion lens  42  or the tele-conversion lens  43  is selected, is not limited to that shown in FIG. 6. For example, each time the pseudo zoom mode push button  22  shown in FIG. 2 is pushed, an on signal and an off signal may be alternately fed from the pseudo zoom switch  61  shown in FIG. 5 into the CPU  60 . In cases where the off signal is fed into the CPU  60 , the CPU  60  may control such that the wide-conversion lens  42  may be combined with the fundamental optical system  31 . Also, in cases where the on signal is fed into the CPU  60 , the CPU  60  may control such that the tele-conversion lens  43  may be combined with the fundamental optical system  31 .  
     [0192] In such cases, the relationship between the magnification ratio of the fundamental optical system  31  and the finder magnification ratio, which is shown in FIG. 10, is obtained.  
     [0193] In such cases, the field angle of the image displayed in the finder will change sharply before the pseudo zoom mode push button  22  is operated and after the pseudo zoom mode push button  22  is operated. However, in such cases, since the photographer operates the pseudo zoom mode push button  22  with the intention of changing the photographing field angle to the tele-side or the wide-angle side, he can feel the sharp change in field angle as being natural.  
     [0194] A second embodiment of the pseudo zoom camera in accordance with the present invention will be described hereinbelow with reference to FIGS. 11, 12,  13 , and  14 . In FIG. 11, similar elements are numbered with the same reference numerals with respect to FIG. 5.  
     [0195] Basically, the second embodiment of the pseudo zoom camera has the same mechanical constitution as that in the first embodiment of the pseudo zoom camera shown in FIG. 1, except that the conversion lens block  32  provided with the wide-conversion lens  42  and the tele-conversion lens  43  is omitted and a zoom optical system having a zoom ratio of 6 is employed as the fundamental optical system  31 . Specifically, in the second embodiment, a zoom lens having a zoom ratio of 3 is employed as the taking lens  10 , and the fundamental optical system  31 , which does not take part in the image quality of the object image, has a zoom ratio higher than the zoom ratio of the taking lens  10 .  
     [0196] In the region in which the zoom ratio of the taking lens  10  takes a value falling within the range of 1 to 3, as in an ordinary camera, in accordance with the zooming operation, the field angle of the image displayed in the finder and the photographing field angle are changed in an interlocked manner. When the zooming operation is carried out to the tele-side beyond this range, only the field angle of the image displayed by the fundamental optical system  31  can be changed, while the photographing field angle is being kept unchanged. How such a control operation is achieved will be described hereinbelow.  
     [0197]FIG. 11 is a block diagram showing an electric control constitution in the second embodiment of the pseudo zoom camera in accordance with the present invention. The constitution shown in FIG. 11 is basically identical with the constitution shown in FIG. 5, except that the pseudo zoom switch  61 , the driver  73 , and the lens change-over actuator  45  are omitted. How a CPU  360  carries out control processing will be described hereinbelow with reference to FIGS. 12, 13, and  14 .  
     [0198]FIG. 12 shows a flow of general control processing carried out by the CPU  360 . As illustrated in FIG. 12, in a step P 10 , the general control processing starts. In a step P 11 , a judgment is made as to whether there is or is not a change in the state of various switches of the camera. In cases where it has been judged that there is no change in the switch state, in a step P 13 , the incorporated clock is updated, and the processing returns to the step P 11 .  
     [0199] In cases where it has been judged in the step P 11  that there is a change in the switch state, in a step P 12 , a judgment is made as to whether the switch whose state has been changed is or is not the main switch  64  shown in FIG. 11. In cases where it has been judged that the switch whose state has been changed is the main switch  64 , in a step P 14 , a judgment is made as to whether the change in the state of the main switch  64  is or is not an off-to-on change.  
     [0200] In cases where it has been judged that the change in the state of the main switch  64  is the off-to-on change, in a step P 15 , open processing for setting the zoom type of taking lens  10  in a waiting state is carried out. Thereafter, in a step P 16 , processing for setting an open flag is carried out. In cases where it has been judged in the step P 14  that the change in the state of the main switch  64  is the on-to-off change, in a step P 17 , close processing for setting the zoom type of taking lens  10  in a retreating state is carried out. Thereafter, in a step P 18 , processing for resetting the open flag is carried out.  
     [0201] After the open flag has been set or reset, or in cases where it has been judged in the step P 12  that the switch whose state has been changed is not the main switch  64 , the processing proceeds to a step P 19 . In the step P 19 , a judgment is made as to whether the open flag is or is not set. In cases where it has been judged that the open flag is not set, the processing returns to the step P 11 . In cases where it has been judged that the open flag is set, in a step P 20 , a judgment is made as to whether the zoom switch  63  shown in FIG. 11 is or is not operated.  
     [0202] In cases where it has been judged that the zoom switch  63  is not operated, the processing proceeds to a step P 22 , which will be described later. In cases where it has been judged that the zoom switch  63  is operated, in a step P 21 , zoom processing is carried out. How the zoom processing is carried out will be described later.  
     [0203] Thereafter, in the step P 22 , a judgment is made as to whether the release switch  62  shown in FIG. 11 is or is not operated. In cases where it has been judged that the release switch  62  is not operated, the processing returns to the step P 11 . In cases where it has been judged that the release switch  62  is operated, in a step P 23 , release processing is carried out. Thereafter, the processing returns to the step P 11 .  
     [0204] How the zoom processing is carried out in the step P 21  will be described hereinbelow with reference to FIG. 13. As illustrated in FIG. 13, in a step P 30 , the subroutine processing for the zooming starts. In a step P 31 , a judgment is made as to whether the operation of the zoom switch  63  is or is not the operation to the tele-side.  
     [0205] In cases where it has been judged that the operation of the zoom switch  63  is the operation to the tele-side, in a step P 32 , processing for zooming the fundamental optical system  31  by a predetermined distance to the tele-side is carried out. As in the aforesaid cases, the zooming is carried out by operating the finder driving motor  79  with the driver  72 . In cases where it has been judged that the operation of the zoom switch  63  is not the operation to the tele-side, i.e. in cases where the zoom switch  63  is operated to the wide-side, in a step P 33 , processing for zooming the fundamental optical system  31  by a predetermined distance to the wide-side is carried out.  
     [0206] The zooming processing to the tele-side or the wide-side is carried out in the manner described above. Thereafter, in a step P 34 , a judgment is made as to whether the zoom switch  63  is or is not operated even further. In cases where it has been judged that the zoom switch  63  is operated even further, in a step P 35 , a judgment is made as to whether the fundamental optical system  31  has or has not reached the tele-end position. In cases where it has been judged that the fundamental optical system  31  has reached the tele-end position, in a step P 37 , the finder driving motor  79  is stopped.  
     [0207] In cases where it has been judged that the fundamental optical system  31  has not reached the tele-end position, in a step P 36 , a judgment is made as to whether the fundamental optical system  31  has or has not reached the wide-end position. In cases where it has been judged that the fundamental optical system  31  has reached the wide-end position, in the step P 37 , the finder driving motor  79  is stopped.  
     [0208] In cases where it has been judged that the fundamental optical system  31  has not reached the wide-end position, the processing returns to the step P 34 , and the same processing as the processing described above is repeated. In cases where it has been judged in the step P 34  that the zoom switch  63  is not operated, in the step P 37 , the finder driving motor  79  is stopped.  
     [0209] When the finder driving motor  79  is thus stopped, in cases where the fundamental optical system  31  is in the state in which the zoom ratio falls within the range of 1 to 3, as described above, the zooming position of the taking lens  10  is such that the zoom ratio may fall within the range of 1 to 3, and the image of the same field angle as the field angle of the image displayed in the finder can be recorded. In cases where the fundamental optical system  31  is in the state in which the zoom ratio falls within the range of 3 to 6, the zooming position of the taking lens  10  is set at the tele-end position at all times.  
     [0210] Thereafter, in a step P 38 , the zooming position of the fundamental optical system  31  is detected. The detection is carried out by utilizing, for example, an output of a linear encoder for detecting the positions of the zoom lenses  36  and  37 .  
     [0211] Thereafter, in a step P 39 , in accordance with the zooming position of the fundamental optical system  31 , the image range ratio of the image, which is displayed in the visual field frame of the finder, to the object image is calculated. Information, which represents the calculated image range ratio, and information, which represents the corresponding frame number, are temporarily stored in a predetermined memory (not shown). Thereafter, in a step P 40 , the subroutine for the zooming is finished. The processing then returns to the flow shown in FIG. 12.  
     [0212] How the release processing in the step P 23  shown in FIG. 12 is carried out will be described hereinbelow with reference to FIG. 14. As illustrated in FIG. 14, in a step P 50 , the subroutine processing for the release starts. Thereafter, in a step P 51 , a battery check is made. In a step P 52 , a judgment is made as to whether the results of the battery check are or are not good. In cases where it has been judged that the battery does not satisfy predetermined performance, in a step P 53 , the results of the battery check are indicated in the finder. Also, in a step P 62 , the subroutine processing is finished.  
     [0213] In cases where it has been judged that in the step P 52  that the results of the battery check are good, in steps P 54 , P 55 , and P 56 , respectively, automatic focusing, photometry, and lens driving processing for the focusing are carried out.  
     [0214] Thereafter, in a step P 57 , a judgment is made as to whether the shutter push button  20  shown in FIG. 2 has or has not reached a predetermined push-down position P 1 . In cases where it has been judged that the shutter push button  20  has not reached the push-down position P 1 , in the step P 62 , the subroutine processing is finished. Also, the processing returns to the flow shown in FIG. 12.  
     [0215] In cases where it has been judged that the shutter push button  20  has reached the push-down position P 1 , in a step P 58 , a judgment is made as to whether the shutter push button  20  has or has not reached a predetermined push-down position P 2 , which is deeper than the push-down position P 1 . In cases where it has been judged that the shutter push button  20  has not reached the push-down position P 2 , the processing returns to the step P 57 . In cases where it has been judged that the shutter push button  20  has reached the push-down position P 2 , in a step P 59 , a release operation is carried out, and the photographing operation is completed.  
     [0216] Thereafter, in a step P 60 , the information, which represents the image range ratio having been calculated in the step P 39  shown in FIG. 13 and which has been stored in the memory together with the information representing the corresponding frame number, is transferred to the storage device  54  of the cartridge  53  shown in FIG. 4 and written on it.  
     [0217] In a step P 61 , the photographic film  51  is fed by a length corresponding to one frame. Thereafter, in a step P 62 , the subroutine is finished. Also, the processing returns to the flow shown in FIG. 12.  
     [0218] After object images have been recorded in the frames of the photographic film  51  accommodated in the film cartridge  50 , the film cartridge  50  is taken out of the camera body  1  and subjected to the development processing in a processing laboratory, or the like. In this manner, the photographic latent images having been recorded on the photographic film  51  are developed. Therefore, in the same manner as that in the embodiment described above, photoprints are formed by the utilization of the developed photographic film  51 A in the photo printing system shown in FIGS. 7 and 8.  
     [0219] In such cases, the pseudo zoom processing is carried out in accordance with the information representing the image range ratio, which is stored together with the information representing the corresponding frame number on the storage device  54  of the cartridge  53 .  
     [0220] At this time, as described above, as for the images having been recorded when the fundamental optical system  31  is set in the state in which the zoom ratio falls within the range of 1 to 3, the field angle is identical with the field angle of the image displayed in the finder. Therefore, as for such images, the relationship between the size of the image recorded on the film and the size of the printed image becomes identical with the relationship shown in FIGS. 9A and 9B. Specifically, as for such images, the pseudo zoom processing is not carried out consequently.  
     [0221] As for the images having been recorded when the fundamental optical system  31  is set in the state in which the zoom ratio falls within the range of 3 to 6, the relationship between the size of the image recorded on the film and the size of the printed image becomes identical with the relationship shown in FIGS. 9A and 9C. Specifically, as for such images, the pseudo zoom processing is carried out.  
     [0222] A third embodiment of the pseudo zoom camera in accordance with the present invention will be described hereinbelow with reference to FIGS. 15, 16,  17 ,  18 , and  19 . In the third embodiment, the blackout processing, i.e. the processing for preventing the finder image to be seen when the finder magnification ratio increases or decreases sharply, is carried out. Only the constitution concerning the blackout processing will be described hereinbelow. As for the other features, the foregoing may be referred to.  
     [0223] As illustrated in FIG. 19, in the third embodiment, a tele-converter on state, in which a tele-conversion lens (a tele-converter) having a magnification ratio of, for example, 3, is combined with the finder optical system, and a tele-converter off state, in which the tele-converter is released from the finder optical system, is set selectively. In this manner, even if the fundamental optical system having a zoom ratio of 3 is employed, a zoom ratio of 9 can be achieved by the entire finder.  
     [0224] Specifically, as illustrated in FIG. 19, in cases where the finder zooming position is set such that the magnification ratio may fall within the range of 1 to 3, the tele-converter off state is set, and the taking lens is operated in the interlocked manner such that the zoom magnification ratio may fall within the range of 1 to 3. In this manner, an image of the same field angle as the field angle of the image displayed in the finder is recorded on the photographic film  51 . In cases where the zoom lever is operated such that the zoom magnification ratio may become higher than 3, the zooming position of the taking lens is kept at the tele-end, and the tele-converter on state is set. Also, the finder zooming position is returned to the wide-end, and the finder is zoomed from the wide-end toward the tele-end.  
     [0225] During the period in which the finder zooming position is returned to the wide-end in the manner described above, the finder LCD (liquid crystal display device), which is incorporated in the finder optical system, is turned on, such that the finder image may not been seen.  
     [0226] In cases where the tele-converter is changed over from the on state to the off state, the operation reverse to the aforesaid operation is carried out.  
     [0227] The flow of the aforesaid processing will hereinbelow be described in detail with reference to FIGS. 15, 16,  17 , and  18 . The processing can be achieved by, for example, the constitution shown in FIG. 5. Explanation of the processing concerning the operation of the taking lens, and the like, will be omitted hereinbelow, and only the processing concerning the finder displaying will be described hereinbelow.  
     [0228] Firstly, how the processing is carried out in the cases of the zooming operation to the tele-side will hereinbelow be described in detail with reference to FIG. 15. In the flow of the general control processing with the CPU shown in FIG. 12, in a step P 101 , the zoom tele processing (i.e., the zooming operation to the tele-side) starts. In a step P 102 , the finder zooming position is detected. Also, in a step P 103 , the tele-converter position is detected.  
     [0229] Thereafter, in a step P 104 , a judgment is made as to whether the finder optical system is or is not set at the maximum zooming position (i.e., the tele-end position). In cases where it has been judged that the finder optical system is set at the maximum zooming position, in a step P 106 , a judgment is made as to whether the tele-converter is or is not in the on state. In cases where it has been judged that the tele-converter is in the on state, in a step P 108 , a judgment is made as to whether the zoom motor operation switch, which is operated by the zoom lever, is or is not off. In cases where it has been judged that the zoom motor operation switch is off, in a step P 109 , the processing returns to the general processing. In cases where it has been judged that the zoom motor operation switch is not off, the processing of the step P 108  is repeated.  
     [0230] In cases where it has been judged in the step P 106  that the tele-converter is in the off state, in a step P 107 , tele-blackout processing (i.e., blackout processing at the time of the zooming operation to the tele-side, which will be described later with reference to FIG. 16) is carried out.  
     [0231] In cases where it has been judged in the step P 104  that the finder optical system is not set at the maximum zooming position (i.e., the tele-end position), in a step P 105 , the operation of the zoom motor is begun such that it may rotate in the forward direction. With the rotation of the zoom motor in the forward direction, the zoom mechanism is operated to the tele-side. The rotation is carried out under duty control such that the zoom mechanism may be operated at a predetermined speed.  
     [0232] When the forward rotation of the zoom motor is begun, in a step P 110 , a judgment is made as to whether the aforesaid zoom motor operation switch is or is not off. In cases where it has been judged that the zoom motor operation switch is off, in a step P 111 , the zoom motor is stopped. Also, in a step P 112 , the processing returns to the general processing. In cases where it has been judged that the zoom motor operation switch is not off, in a step P 113 , a judgment is made as to whether the zoom motor is or is not operating.  
     [0233] In cases where it has been judged that the zoom motor is operating, in a step P 114 , the finder zooming position is detected. Also, in a step P 115 , a judgment is made as to whether the finder optical system is or is not set at the maximum zooming position (i.e., the tele-end position). In cases where it has been judged that the finder optical system is not set at the maximum zooming position, the processing returns to the step P 110 . In cases where it has been judged that the finder optical system is set at the maximum zooming position, in a step P 116 , the zoom motor is stopped.  
     [0234] After the zoom motor has been stopped, in a step P 117 , a judgment is made as to whether the tele-converter is or is not in the on state. In cases where it has been judged that the tele-converter is in the on state, in a step P 118 , a judgment is made as to whether the zoom motor operation switch is or is not off. In cases where it has been judged that the zoom motor operation switch is off, in a step P 119 , the processing returns to the general processing. In cases where it has been judged that the zoom motor operation switch is not off, the processing of the step P 118  is repeated. In cases where it has been judged in the step P 113  that the zoom motor is not operating, the processing proceeds to the step P 117 .  
     [0235] In cases where it has been judged in the step P 117  that the tele-converter is in the off state, in a step P 120 , the tele-blackout processing is carried out.  
     [0236] How the tele-blackout processing is carried out will be described hereinbelow with reference to FIG. 16. In a step P 131 , the tele-blackout processing starts. In a step P 132 , the aforesaid LCD is turned on, such that the image displayed in the finder cannot be seen. Thereafter, in a step P 133 , the zoom motor is operated such that it may rotate in the reverse direction. With the rotation of the zoom motor in the reverse direction, the zoom mechanism is operated to the wide-side. Instead of being carried out under the duty control described above, the rotation is carried out, for example, in an ordinary DC driving mode, such that the finder zooming position may quickly return to the wide-end.  
     [0237] After the reverse rotation of the zoom motor is begun, in a step P 134 , the operation of a converter motor, which moves the tele-converter, is begun such that it may rotated in the forward direction. With the rotation of the converter motor in the forward direction, the tele-converter is set at the position that is combined with the finder optical system.  
     [0238] Thereafter, in a step P 135 , a judgment is made as to whether the zoom motor is or is not operating. In cases where it has been judged that the zoom motor is operating, in a step P 136 , the finder zooming position is detected. Also, in a step P 137 , a judgment is made as to whether the finder optical system is or is not set at the minimum zooming position (i.e., the wide-end position). In cases where it has been judged that the finder optical system is set at the minimum zooming position, in a step P 138 , the zoom motor is stopped. Thereafter, in a step P 139 , a judgment is made as to whether the converter motor is or is not operating. In cases where it has been judged in the step P 135  that the zoom motor is not operating, and in cases where it has been judged in the step P 137  that the finder optical system is not set at the minimum zooming position, the processing proceeds to the aforesaid step P 139 .  
     [0239] In cases where it has been judged in the step P 139  that the converter motor is operating, in a step P 140 , the tele-converter position is detected. Also, in a step P 141 , a judgment is made as to whether or not the setting of the tele-converter has been finished such that it may be normally combined with the finder optical system. In cases where it has been judged that the setting of the tele-converter has been finished, in a step P 142 , the converter motor is stopped. Also, in a step P 143 , a judgment is made as to whether both the converter motor and the zoom motor have or have not been stopped.  
     [0240] In cases where it has been judged in the step P 139  that the converter motor is not operating, and in cases where it has been judged in the step P 141  that the setting of the tele-converter has not been finished, the processing proceeds to the aforesaid step P 143 . In cases where it has been judged in the step P 143  that the converter motor and the zoom motor have not been stopped, the processing returns to the step P 135 .  
     [0241] In cases where it has been judged in the step P 143  that the converter motor and the zoom motor have been stopped, in a step P 144 , the aforesaid LCD is turned off, such that the image displayed in the finder can be seen. Also, in a step P 145 , the processing returns to the general processing.  
     [0242] How the zooming operation to the wide-side and the blackout processing at the time of the zooming operation to the wide-side are carried out will be described hereinbelow with reference to FIGS. 17 and 18. With reference to FIG. 17, in a step P 150 , the zoom wide processing (i.e., the zooming operation to the wide-side) starts. In a step P 151 , the finder zooming position is detected. Also, in a step P 152 , the tele-converter position is detected.  
     [0243] Thereafter, in a step P 153 , a judgment is made as to whether the finder optical system is or is not set at the minimum zooming position (i.e., the wide-end position). In cases where it has been judged that the finder optical system is set at the minimum zooming position, in a step P 155 , a judgment is made as to whether the tele-converter is or is not in the off state. In cases where it has been judged that the tele-converter is in the off state, in a step P 157 , a judgment is made as to whether the zoom motor operation switch, which is operated by the zoom lever, is or is not off. In cases where it has been judged that the zoom motor operation switch is off, in a step P 158 , the processing returns to the general processing. In cases where it has been judged that the zoom motor operation switch is not off, the processing of the step P 157  is repeated.  
     [0244] In cases where it has been judged in the step P 155  that the tele-converter is in the on state, in a step P 156 , wide-blackout processing (i.e., blackout processing at the time of the zooming operation to the wide-side, which will be described later with reference to FIG. 18) is carried out.  
     [0245] In cases where it has been judged in the step P 153  that the finder optical system is not set at the minimum zooming position (i.e., the wide-end position), in a step P 154 , the operation of the zoom motor is begun such that it may rotate in the reverse direction. With the rotation of the zoom motor in the reverse direction, the zoom mechanism is operated to the wide-side. The rotation is carried out under duty control such that the zoom mechanism may be operated at a predetermined speed.  
     [0246] When the reverse rotation of the zoom motor is begun, in a step P 159 , a judgment is made as to whether the aforesaid zoom motor operation switch is or is not off. In cases where it has been judged that the zoom motor operation switch is off, in a step P 161 , the zoom motor is stopped. Also, in a step P 162 , the processing returns to the general processing. In cases where it has been judged that the zoom motor operation switch is not off, in a step P 160 , a judgment is made as to whether the zoom motor is or is not operating.  
     [0247] In cases where it has been judged that the zoom motor is operating, in a step P 163 , the finder zooming position is detected. Also, in a step P 164 , a judgment is made as to whether the finder optical system is or is not set at the minimum zooming position (i.e., the wide-end position). In cases where it has been judged that the finder optical system is not set at the minimum zooming position, the processing returns to the step P 159 . In cases where it has been judged that the finder optical system is set at the minimum zooming position, in a step P 165 , the zoom motor is stopped.  
     [0248] After the zoom motor has been stopped, in a step P 166 , a judgment is made as to whether the tele-converter is or is not in the off state. In cases where it has been judged that the tele-converter is in the off state, in a step P 167 , a judgment is made as to whether the zoom motor operation switch is or is not off. In cases where it has been judged that the zoom motor operation switch is off, in a step P 168 , the processing returns to the general processing. In cases where it has been judged that the zoom motor operation switch is not off, the processing of the step P 167  is repeated. In cases where it has been judged in the step P 160  that the zoom motor is not operating, the processing proceeds to the step P 166 .  
     [0249] In cases where it has been judged in the step P 166  that the tele-converter is in the on state, in a step P 169 , the wide-blackout processing is carried out.  
     [0250] How the wide-blackout processing is carried out will be described hereinbelow with reference to FIG. 18. In a step P 170 , the wide-blackout processing starts. In a step P 171 , the aforesaid LCD is turned on, such that the image displayed in the finder cannot be seen. Thereafter, in a step P 172 , the zoom motor is operated such that it may rotate in the forward direction. With the rotation of the zoom motor in the forward direction, the zoom mechanism is operated to the tele-side. Instead of being carried out under the duty control described above, the rotation is carried out, for example, in an ordinary DC driving mode, such that the finder zooming position may quickly return to the tele-end.  
     [0251] After the forward rotation of the zoom motor is begun, in a step P 173 , the operation of a converter motor, which moves the tele-converter, is begun such that it may rotated in the reverse direction. With the rotation of the converter motor in the reverse direction, the tele-converter is set at the position that is released from the finder optical system.  
     [0252] Thereafter, in a step P 174 , a judgment is made as to whether the zoom motor is or is not operating. In cases where it has been judged that the zoom motor is operating, in a step P 175 , the finder zooming position is detected. Also, in a step P 176 , a judgment is made as to whether the finder optical system is or is not set at the maximum zooming position (i.e., the tele-end position). In cases where it has been judged that the finder optical system is set at the maximum zooming position, in a step P 177 , the zoom motor is stopped. Thereafter, in a step P 178 , a judgment is made as to whether the converter motor is or is not operating. In cases where it has been judged in the step P 174  that the zoom motor is not operating, and in cases where it has been judged in the step P 176  that the finder optical system is not set at the maximum zooming position, the processing proceeds to the aforesaid step P 178 .  
     [0253] In cases where it has been judged in the step P 178  that the converter motor is operating, in a step P 179 , the tele-converter position is detected. Also, in a step P 180 , a judgment is made as to whether or not the setting of the tele-converter has been finished such that it may be normally released from the finder optical system. In cases where it has been judged that the setting of the tele-converter has been finished, in a step P 181 , the converter motor is stopped. Also, in a step P 182 , a judgment is made as to whether both the converter motor and the zoom motor have or have not been stopped.  
     [0254] In cases where it has been judged in the step P 178  that the converter motor is not operating, and in cases where it has been judged in the step P 180  that the setting of the tele-converter has not been finished, the processing proceeds to the aforesaid step P 182 . In cases where it has been judged in the step P 182  that the converter motor and the zoom motor have not been stopped, the processing returns to the step P 174 .  
     [0255] In cases where it has been judged in the step P 182  that the converter motor and the zoom motor have been stopped, in a step P 183 , the aforesaid LCD is turned off, such that the image displayed in the finder can be seen. Also, in a step P 184 , the processing returns to the general processing.  
     [0256] In the third embodiment described above, as indicated by the solid line in FIG. 19, the rate of change in finder zooming position per unit time is kept the same between when the tele-converter is used and when the tele-converter is not used. Alternatively, as indicated by the single-dot chained line in FIG. 19, the rate of change in finder zooming position per unit time when the tele-converter is used may be set to be lower than the rate of change when the tele-converter is not used. In such cases, the sharp change in magnification ratio of the image displayed in the finder due to the use of the tele-converter can be relieved, and confirmation of the visual field range can be carried out easily.  
     [0257] Also, as indicated by the double-dot chained line in FIG. 19, in accordance with the relationship between the tele-converter magnification ratio and the zoom ratio of the finder zoom optical system, when the tele-converter on state and the tele-converter off state are changed over to each other, the finder zooming position may not be returned to the tele-end or the wide-end. In such cases, after the state of the tele-converter is changed over to the on state, the maximum magnification ratio can be reached quickly. Therefore, in such cases, the rate of change in finder zooming position per unit time should preferably be set to be particularly low.  
     [0258] In the third embodiment described above, the blackout is carried out by using the liquid crystal display device. Alternatively, the blackout may be carried out by using one of various other means. FIG. 20 is a front view showing a blackout means for mechanically carrying out the blackout in a fourth embodiment of the pseudo zoom camera in accordance with the present invention. FIG. 21 is a front view showing a different state of the blackout means shown in FIG. 20. In the blackout means, a light blocking plate  250  has two slide grooves  251 ,  251 . Engagement pins  252 ,  252 , which are secured to the camera body side, are inserted respectively through the slide grooves  251 ,  251 . The light blocking plate  250  can thereby move horizontally in FIG. 20. Also, the light blocking plate  250  is provided with a light passage window  253 , which matches with an optical axis O of the finder optical system when the finder is used.  
     [0259] The light blocking plate  250  is further provided with a dogleg-like slide groove  254 . A pin  260  is inserted through the slide groove  254 . The pin  260  is secured to an end of a connection bar  261 , which is swung by the lens change-over actuator  45 . In this embodiment, the tele-conversion lens  43  is set selectively to the state, in which it is combined with the finder optical system, or to the state, in which it is released from the finder optical system. The tele-conversion lens  43  is moved by, for example, a combination of the pinion gear (not shown in FIG. 20), which is driven by the lens change-over actuator  45 , and the rack (not shown in FIG. 20). The tele-conversion lens  43  is thereby selectively set to one of the two states.  
     [0260]FIG. 20 shows the state, in which the tele-conversion lens  43  is not used. In this state, the light passage window  253  is matched with the optical axis O of the finder optical system. The lens change-over actuator  45  may then operates for moving the tele-conversion lens  43  to the position that matches with the optical axis O of the finder optical system. As a result, the connection bar  261  is swung, and the light blocking plate  250  is moved to the right in FIG. 20.  
     [0261] As illustrated in FIG. 21, when the pin  260  reaches the middle part of the slide groove  254 , the tele-conversion lens  43  is located at an intermediate position of the movement to the position that matches with the optical axis O of the finder optical system. At this time, the light blocking plate  250  is located at the right end position of the horizontal movement range, and the light passage window  253  is located at the position spaced apart from the optical axis O of the finder optical system. In this state, the finder optical path is blocked by the light blocking plate  250 . In this manner, the blackout can be carried out.  
     [0262] When the lens change-over actuator  45  operates even further from the state shown in FIG. 21 and the pin  260  reaches the lower end of the slide groove  254 , the light blocking plate  250  returns to the position shown in FIG. 20. At this time, the tele-conversion lens  43  perfectly matches with the optical axis O of the finder optical system.  
     [0263] An embodiment of the zoom finder in accordance with the present invention will be described hereinbelow.  
     [0264] The embodiment of the zoom finder is constituted in the same manner as that in the finder optical system  30  in the aforesaid first embodiment of the pseudo zoom camera in accordance with the present invention. In this case, the fundamental optical system  31  shown in FIG. 1 constitutes the zoom optical system of the zoom finder.  
     [0265] An image, which has been recorded on the photographic film  51  by using the pseudo zoom camera, is subjected to the pseudo zoom processing, which is carried out by the photo printing system shown in FIG. 7 in the manner described above.  
     [0266] The relationship between the photographing field angle and the field angle of the printed image with the pseudo zoom processing is identical with the relationship between the field angle of an image, which is formed by a taking lens, and the field angle of a recorded image in an electronic still camera, a video camera, or the like, in which electronic zoom functions are employed. Therefore, in cases where the zoom finder in accordance with the present invention is employed with respect to the electronic still camera, the video camera, or the like, the same effects as those described above can be obtained.  
     [0267] The zoom finder in accordance with the present invention may be embodied in the same manner as that in the aforesaid third or fourth embodiment of the pseudo zoom camera in accordance with the present invention.  
     [0268] A fifth embodiment of the pseudo zoom camera in accordance with the present invention will be described hereinbelow. The fifth embodiment of the pseudo zoom camera has the same appearance as that shown in FIG. 2. FIG. 22 shows a finder optical system in the fifth embodiment of the pseudo zoom camera. In FIG. 22, similar elements are numbered with the same reference numerals with respect to FIG. 1.  
     [0269] As illustrated in FIG. 22, the finder (the finder optical system)  30  comprises the zoom optical system (the fundamental optical system)  31  and a conversion lens block  332 .  
     [0270] The zoom optical system  31  has the same constitution as that of the fundamental optical system  31  shown in FIG. 1.  
     [0271] The conversion lens block  332  is provided with a window  342 , which allows light to pass therethrough. Also, the tele-conversion lens  43  is secured to the conversion lens block  332 . By way of example, the tele-conversion lens  43  enlarges the finder image, which is formed by the zoom optical system  31 , to a size 2 times as large as the original size (i.e., q=2).  
     [0272]FIG. 23 is an exploded perspective view showing the major part of the fifth embodiment of the pseudo zoom camera. As illustrated in FIG. 23, the conversion lens block  332  is provided with the rack  44 , which extends vertically. The pinion gear  46 , which is rotated by the lens change-over actuator  45 , is engaged with the rack  44 .  
     [0273] In the fifth embodiment of the pseudo zoom camera, the film cartridge  50  shown in FIG. 4 is utilized. The electric control constitution in the fifth embodiment of the pseudo zoom camera is the same as that shown in FIG. 5.  
     [0274] How the fifth embodiment of the pseudo zoom camera operates will be described hereinbelow. In this embodiment, by way of example, the taking lens  10  has a zoom magnification ratio, n, of 2, and the zoom optical system  31  of the finder  30  has a zoom magnification ratio, p, of 3. Also, the pseudo zoom magnification ratio in the printing process is at most 3 (m=3).  
     [0275]FIG. 24 shows a change in focal length magnification ratio with the taking lens  10  and the zoom optical system  31 , as well as with the tele-conversion lens  43  and the pseudo zoom processing. The change in focal length magnification ratio with the pseudo zoom processing, which change is shown in FIG. 24, is the apparent one.  
     [0276] In the range of the zoom magnification ratio of 2, which the taking lens  10  covers, i.e. a region A shown in FIG. 24, the conversion lens block  332  is forcibly located at the position, such that the window  342  may be aligned with the optical axis of the zoom optical system  31 . Specifically, the tele-conversion lens  43  is set at the position that is released from the zoom optical system  31 . In this region, alteration of the photographing field angle is carried out in the same manner as that in an ordinary 35 mm lens shutter camera provided with a zoom lens, or the like.  
     [0277] Specifically, when the zoom lever  21  is operated to a tele-side or a wide-side (i.e., a wide-angle side), a tele-operation signal or a wide-operation signal is fed from the zoom switch  63  shown in FIG. 5 into the CPU  60 . The feeding of the tele-operation signal or the wide-operation signal into the CPU  60  is continued until the operation of the zoom lever  21  is stopped.  
     [0278] When the CPU  60  receives the tele-operation signal, it feeds a control signal, which instructs tele-side driving, to the driver  72 . Also, the zoom driving motor  78  and the finder driving motor  79  receive driving current from the driver  72  and rotate in directions that set the focal lengths of the taking lens  10  and the zoom optical system  31 , respectively, at large values.  
     [0279] When the CPU  60  receives the wide-operation signal, it feeds a control signal, which instructs wide-side driving, to the driver  72 . Also, the zoom driving motor  78  and the finder driving motor  79  receive driving current from the driver  72  and rotate in directions that set the focal lengths of the taking lens  10  and the zoom optical system  31 , respectively, at small values.  
     [0280] In each of the taking lens  10  and the zoom optical system  31 , a predetermined number of lenses are moved along the optical axis direction by a known cam mechanism, which receives the rotation force of the corresponding zoom driving motor  78  or the corresponding finder driving motor  79 , and the focal length is thereby changed. In this manner, in the region in which the zoom magnification ratio is at most 2, the field angle of the object image, which is formed by the taking lens  10 , and the field angle of the finder image, which is displayed by the finder  30 , are changed such that the field angles of the object image and the finder image may be kept identical with each other.  
     [0281] When the operation of the zoom lever  21  is stopped, the feeding of the tele-operation signal or the wide-operation signal into the CPU  60  is ceased, and the zoom driving motor  78  and the finder driving motor  79  are stopped. At this time, the taking lens  10  is set in the state, in which an image of a field angle identical with the field angle of the finder image displayed in a visual field frame of the visual field plate  40  is formed on the photographic film  51 . Therefore, when the shutter push button  20  is pushed in this state, predetermined automatic focusing processing and automatic exposure processing are carried out, and a photographic latent image of the aforesaid field angle is recorded on the photographic film  51 .  
     [0282] In FIG. 22, wide-end positions of the zoom lenses  36  and  37  are indicated by the solid lines, and tele-end positions of them are indicated by the broken lines. When the zoom lenses  36  and  37  take the wide-end positions, the taking lens  10  is set in the state, in which the focal length is shortest. Also, when the zoom lenses  36  and  37  take the positions, such that the zoom magnification ratio may become equal to 2, the taking lens  10  is set in the state, in which the focal length is longest, i.e. at the tele-end positions.  
     [0283] In a region B shown in FIG. 24, in which the zoom magnification ratio of the zoom optical system  31  is higher than 2, the taking lens  10  is kept at the tele-end position. Also, in accordance with an intention of the photographer, one of the state, in which the tele-conversion lens  43  is used, and the state, in which the tele-conversion lens  43  is not used, is set selectively.  
     [0284] Specifically, each time the pseudo zoom mode push button  22  shown in FIG. 2 is pushed one time, an on signal and an off signal are alternately fed from the pseudo zoom switch  61  shown in FIG. 5 into the CPU  60 . Also, the CPU  60  controls the lens change-over actuator  45  in accordance with the received signals. In cases where the off signal is fed into the CPU  60 , the conversion lens block  332  is set such that the window  342  may coincide with the optical axis of the zoom optical system  31 . In cases where the on signal is fed into the CPU  60 , the conversion lens block  332  is set such that the tele-conversion lens  43  may coincide with the optical axis of the zoom optical system  31 .  
     [0285] In cases where the tele-conversion lens  43  is not used, in accordance with the operation of the zoom lever  21 , the zoom magnification ratio of the zoom optical system  31  (in this case, the zoom magnification ratio of the entire finder) is set at a value falling within the range of 2 to 3. However, since the taking lens  10  is kept at the tele-end position as described above, the photographing field angle does not change.  
     [0286] Each time the shutter push button  20  is pushed and an object image, which is formed by the taking lens  10 , is recorded on the photographic film  51 , in this region, the CPU  60  writes the information, which represents the image range ratio of the image displayed in the finder to the object image of the predetermined field angle, and the information, which represents the frame number of the frame that records the object image, on the storage device  54  of the cartridge  53 .  
     [0287] In cases where the tele-conversion lens  43  is used, in accordance with the operation of the zoom lever  21 , the zoom magnification ratio of the zoom optical system  31  is set at a value falling within the range of 2 to 3. In such cases, with the effects of the tele-conversion lens  43  having a magnification ratio of 2, the zoom magnification ratio of the entire finder takes a value falling within the range of 4 to 6 (in the tele-conversion region shown in FIG. 24). Also, since the taking lens  10  is kept at the tele-end position as described above, the photographing field angle does not change.  
     [0288] Each time the shutter push button  20  is pushed and an object image, which is formed by the taking lens  10 , is recorded on the photographic film  51 , in this region, the CPU  60  writes the information, which represents the image range ratio of the image displayed in the finder to the object image of the predetermined field angle, and the information, which represents the frame number of the frame that records the object image, on the storage device  54  of the cartridge  53 . The writing of the information may be carried out with a contact technique via a contact point or with a non-contact technique.  
     [0289] An image, which has been recorded on the photographic film  51  by using the pseudo zoom camera, is subjected to the pseudo zoom processing, which is carried out by the photo printing system shown in FIG. 7 in the manner described above.  
     [0290] How the pixel density conversion for the pseudo zoom processing is carried out by the image size enlargement or reduction processing means  112  in the system constitution shown in FIG. 8 will be described hereinbelow. The image size enlargement or reduction processing means  112  receives the storage information H of each of frames of the photographic film  51 A from the reading means  103 . As described above, the storage information H represents an image range ratio R of the image displayed in the finder to the object image.  
     [0291] In the region A shown in FIG. 24, the image range ratio R is “1” at all times. With respect to the frame associated with the image range ratio of “1,” the image size enlargement or reduction processing means  112  does not carry out the pixel density conversion processing for the image size enlargement or reduction. Specifically, in such cases, printing processing is carried out such that an image shown in FIG. 9A, which has been recorded in a certain frame F on the developed photographic film  51 A, may be reproduced on a recording material  200  having a predetermined size as shown in FIG. 9B, such that the image size may not be enlarged or reduced. In this manner, in such cases, a print, on which an image of the same field angle as the field angle of the image displayed in the finder has been recorded, is obtained.  
     [0292] In the regions B and C shown in FIG. 24, the image range ratio R, which is represented by the storage information H, takes a value falling within the range of 1 to 3. With respect to the frame associated with the image range ratio taking such a value, the image size enlargement or reduction processing means  112  carries out the image size enlargement processing on the image signal, which has been detected by the scanner  110 , such that, for example, the center point of the photographic image may not be shifted, and such that only a range of 1/R in horizontal and vertical directions may be reproduced on the recording material  200  having a predetermined size. The image size enlargement processing is carried out with a scale of image size enlargement of at most 3. Specifically, in such cases, printing processing is carried out such that, of an image shown in FIG. 9A, which has been recorded in a certain frame F on the developed photographic film  51 A, only the region surrounded by the double-dot chained lines shown in FIG. 3A may be reproduced on the recording material  200  as shown in FIG. 9C.  
     [0293] As described above, with the fifth embodiment of the pseudo zoom camera and this embodiment of the photo printing system in accordance with the present invention, even if the taking lens  10  having a zoom magnification ratio of 2 is employed, a photoprint can be obtained as if it were photographed with a taking lens having a zoom magnification ratio of 6. Also, the field angle of the image, which will be printed with an enlarged size through the pseudo zoom operation, can be confirmed through the finder at the time of the photographing operation.  
     [0294] In the fifth embodiment of the pseudo zoom camera in accordance with the present invention, the zoom magnification ratio of the taking lens  10  is set to be 2, which is lower than the zoom magnification ratio (=3) of the zoom optical system  31 . Therefore, the taking lens  10  can be prevented from becoming large in size and expensive in cost due to an increase in zoom magnification ratio, and the pseudo zoom camera can be kept comparatively small in size and cheap in cost.  
     [0295] Also, with the fifth embodiment of the pseudo zoom camera, the zoom magnification ratio (=3) of the zoom optical system  31  is higher than the zoom magnification ratio (=2) of the taking lens  10 . Therefore, as the tele-conversion lens  43 , which is apt to become large in size and expensive in cost due to an increase in magnification ratio, a tele-conversion lens having a comparatively low magnification ratio (=2) can be employed. Therefore, also with this feature, the pseudo zoom camera can be kept small in size and cheap in cost.  
     [0296] In the fifth embodiment of the pseudo zoom camera in accordance with the present invention, the maximum zoom magnification ratio, m, in the pseudo zoom operation, the zoom magnification ratio, n, of the taking zoom lens, the zoom magnification ratio, p, of the finder zoom optical system, and the zoom magnification ratio, q, of the tele-conversion lens are not limited to the values described above.  
     [0297] An embodiment of the camera in accordance with the present invention will be described hereinbelow.  
     [0298]FIG. 25 is a perspective view showing an embodiment of the camera in accordance with the present invention. FIG. 26 is a side view showing a finder optical system in the camera shown in FIG. 25.  
     [0299] As illustrated in FIG. 25, the camera is provided with the taking lens  10  constituted of a zoom lens, the finder window  11 , the AE (automatic exposure) light receiving window  12 , the AF (automatic focusing) light projecting window  13 , the strobe flashing section  15 , and the like, which are located at the front surface of the body  1 . Also, the shutter push button  20 , the zoom lever  21 , a correction mode switch  422 , and the like, are located at the top surface of the body  1 .  
     [0300] A finder optical system  430  shown in FIG. 26 is an ordinary relay type of real image finder optical system. The finder optical system  430  comprises the objective lens  35 , the zoom lenses  36  and  37 , the relay lens  38 , the focal plate  39  on which a finder image is formed, the visual field plate  40  which indicates the range of an image recorded, the eyepiece  41 , and the like.  
     [0301] In this camera, the film cartridge  50  shown in FIG. 4 is utilized.  
     [0302]FIG. 27 is a block diagram showing an electric control constitution in the camera shown in FIG. 25. As illustrated in FIG. 27, the electric circuitry of the camera is provided with a central processing unit (CPU)  460 , which controls fundamental operations of the camera. The CPU  460  receives signals from the correction mode switch  422 , the release switch  62 , the zoom switch  63 , the main switch  64 , and the sensor  65 . (The sensor  65  represents a group of various kinds of sensors.)  
     [0303] Also, the CPU  460  is connected to the liquid crystal display device (LCD)  66  which displays various kinds of information in, for example, the finder, the photometric device  67  for determining a correct exposure, the AF circuit  68 , a strobe flash tube  403 , and the drivers  70 ,  71 , and  72 . Each of these devices is controlled by the CPU  460 . Further, the CPU  460  is connected to a table memory  80 , which will be described later.  
     [0304] The driver  70  drives a film wind-up motor  74  and a lens driving motor  75 . The driver  71  drives the shutter driving motor  76  and the reflector driving motor  77  for operating a reflector of the strobe, which will be described later. The driver  72  drives the zoom driving motor  78  and the finder driving motor  79 .  
     [0305] In the taking lens  10 , a predetermined number of lenses are moved along the optical axis direction by a known cam mechanism, which receives the rotation force of the zoom driving motor  78 , and the focal length is thereby changed. Also, in the finder optical system  430 , the zoom lenses  36  and  37  are moved along the optical axis direction by a known cam mechanism, which receives the rotation force of the finder driving motor  79 , and the focal length is thereby changed. In FIG. 26, the wide-end positions of the zoom lenses  36  and  37  are indicated by the solid lines, and the tele-end positions of them are indicated by the broken lines.  
     [0306]FIGS. 32A and 32B show the strobe flashing section  15  in the camera shown in FIG. 25. The strobe flashing section  15  comprises an optical panel (a Fresnel plate)  400 , which is secured to the front surface of the camera body, a reflector (a reflecting plate)  402 , which is located at the rear of the optical panel  400 , and the strobe flash tube  403 , which is located at a position inside of the space defined by the reflector  402 . As illustrated in FIGS. 32A and 32B, the reflector  402  and the strobe flash tube  403  are driven by the aforesaid reflector driving motor  77  and can be moved together in the forward and backward directions in the camera such that the distances of them from the optical panel  400  may be altered.  
     [0307]FIG. 33 is an explanatory diagram showing a change in light distribution characteristics of the strobe flashing section  15 , which change occurs when the reflector  402  and the strobe flash tube  403  are moved. In cases where the distances of the reflector  402  and the strobe flash tube  403  from the optical panel  400  are comparatively short, the light distribution characteristics indicated by the solid line in FIG. 33 may be obtained. In such cases, when the distances are set to be comparatively long, the light distribution characteristics change to the characteristics indicated by the broken line in FIG. 33. Specifically, in the latter case, the decrease in peripheral light quantity becomes larger than in the former case. Also, in the latter case, the center light quantity becomes large, and the light throw distance becomes long.  
     [0308] The table memory  80  shown in FIG. 27 stores information representing appropriate movement distances of the reflector  402  and the strobe flash tube  403  from the optical panel  400 . The appropriate movement distances are set with respect to each zooming position of the taking lens  10 .  
     [0309] How the photographing operation with this embodiment of the camera is carried out will be described hereinbelow. In this embodiment of the camera, the taking lens  10  having a zoom magnification ratio of 3 is employed. As the finder optical system  430 , a zoom optical system having a zoom magnification ratio of 6 is employed. Specifically, in this case, the finder optical system  430 , which does not take part in the image quality of the object image, has a zoom magnification ratio higher than the zoom magnification ratio of the taking lens  10 .  
     [0310] In the region in which the zoom ratio of the taking lens  10  takes a value falling within the range of 1 to 3, as in an ordinary camera, in accordance with the zooming operation, the field angle of the image displayed in the finder and the photographing field angle are changed in an interlocked manner. When the zooming operation is carried out to the tele-side beyond this range, only the field angle of the image displayed by the finder optical system  430  can be changed, while the photographing field angle is being kept unchanged. In such cases, the CPU  460  writes the storage information H, which represents the image range ratio of the image displayed by the finder optical system  430  to the object image, on the storage device  54  of the film cartridge  50  shown in FIG. 4.  
     [0311] How the zoom control processing, the processing for altering the light distribution characteristics of the strobe flashing section  15 , and the like, are carried out by the CPU  460  shown in FIG. 27 will be described hereinbelow with reference to FIGS. 28, 29,  30 , and  31 .  
     [0312]FIG. 28 shows a flow of general control processing carried out by the CPU  460 . As illustrated in FIG. 28, in a step P 10 , the general control processing starts. In a step P 11 , a judgment is made as to whether there is or is not a change in the state of various switches of the camera. In cases where it has been judged that there is no change in the switch state, in a step P 13 , the incorporated clock is updated, and the processing returns to the step P 11 .  
     [0313] In cases where it has been judged in the step P 11  that there is a change in the switch state, in a step P 12 , a judgment is made as to whether the switch whose state has been changed is or is not the main switch  64  shown in FIG. 27. In cases where it has been judged that the switch whose state has been changed is the main switch  64 , in a step P 14 , a judgment is made as to whether the change in the state of the main switch  64  is or is not an off-to-on change.  
     [0314] In cases where it has been judged that the change in the state of the main switch  64  is the off-to-on change, in a step P 15 , open processing for setting the zoom type of taking lens  10  in a waiting state is carried out. Thereafter, in a step P 16 , processing for setting an open flag is carried out. In cases where it has been judged in the step P 14  that the change in the state of the main switch  64  is the on-to-off change, in a step P 17 , close processing for setting the zoom type of taking lens  10  in a retreating state is carried out. Thereafter, in a step P 18 , processing for resetting the open flag is carried out.  
     [0315] After the open flag has been set or reset, or in cases where it has been judged in the step P 12  that the switch whose state has been changed is not the main switch  64 , the processing proceeds to a step P 19 . In the step P 19 , a judgment is made as to whether the open flag is or is not set. In cases where it has been judged that the open flag is not set, the processing returns to the step P 11 . In cases where it has been judged that the open flag is set, in a step P 20 , a judgment is made as to whether the correction mode switch  422  (shown in FIGS. 25 and 27) is or is not operated.  
     [0316] In cases where it has been judged that the correction mode switch  422  is operated, in a step P 21 , correction mode processing, which will be described later, is carried out. The processing then proceeds to a step P 22 . In cases where it has been judged that the correction mode switch  422  is not operated, the processing proceeds from the step P 20  to the step P 22 .  
     [0317] In the step P 22 , a judgment is made as to whether the zoom switch  63  shown in FIG. 27 is or is not operated. In cases where it has been judged that the zoom switch  63  is not operated, the processing proceeds to a step P 24 , which will be described later. In cases where it has been judged that the zoom switch  63  is operated, in a step P 23 , zoom processing is carried out. How the zoom processing is carried out will be described later.  
     [0318] Thereafter, in the step P 24 , a judgment is made as to whether the release switch  62  shown in FIG. 27 is or is not operated. In cases where it has been judged that the release switch  62  is not operated, the processing returns to the step P 11 . In cases where it has been judged that the release switch  62  is operated, in a step P 25 , release processing is carried out. Thereafter, the processing returns to the step P 11 .  
     [0319] How the correction mode processing is carried out in the step P 21  will be described hereinbelow with reference to FIG. 29. As illustrated in FIG. 29, in a step P 70 , the subroutine processing for the correction mode processing starts. In a step P 71 , a judgment is made as to whether the operation of the correction mode switch  422  is or is not an off-to-on operation.  
     [0320] In cases where it has been judged that the operation of the correction mode switch  422  is the off-to-on operation, in a step P 72 , a judgment is made as to whether the correction flag is or is not set. In cases where it has been judged that the correction flag is set, in a step P 73 , the correction flag is reset. In cases where it has been judged that the correction flag is not set, in a step P 74 , the correction flag is set.  
     [0321] When the correction flag has been set or reset, in a step P 75 , the indication on the LCD  66  shown in FIG. 27 is updated. With the updating operation, the indication that the correction mode is on is displayed or erased. Thereafter, in a step P 76 , the subroutine is finished. Also, the processing returns to the flow shown in FIG. 28.  
     [0322] How the zoom processing is carried out in the step P 23  shown in FIG. 28 will be described hereinbelow with reference to FIG. 30. As illustrated in FIG. 30, in a step P 30 , the subroutine processing for the zoom processing starts. In a step P 31 , a judgment is made as to whether the operation of the zoom switch  63  is or is not the operation to the tele-side.  
     [0323] In cases where it has been judged that the operation of the zoom switch  63  is the operation to the tele-side, in a step P 32 , processing for zooming the taking lens  10  by a predetermined distance to the tele-side is carried out. The zooming is carried out by operating the zoom driving motor  78  with the driver  72 . In cases where it has been judged that the operation of the zoom switch  63  is not the operation to the tele-side, i.e. in cases where the zoom switch  63  is operated to the wide-side, in a step P 33 , processing for zooming the taking lens  10  by a predetermined distance to the wide-side is carried out.  
     [0324] The zooming processing to the tele-side or the wide-side is carried out in the manner described above. Thereafter, in a step P 34 , a judgment is made as to whether the zoom switch  63  is or is not operated even further. In cases where it has been judged that the zoom switch  63  is operated even further, in a step P 35 , a judgment is made as to whether the taking lens  10  has or has not reached the tele-end position. In cases where it has been judged that the taking lens  10  has reached the tele-end position, in a step P 37 , the zoom driving motor  78  is stopped.  
     [0325] In cases where it has been judged that the taking lens  10  has not reached the tele-end position, in a step P 36 , a judgment is made as to whether the taking lens  10  has or has not reached the wide-end position. In cases where it has been judged that the taking lens  10  has reached the wide-end position, in the step P 37 , the zoom driving motor  78  is stopped.  
     [0326] In cases where it has been judged that the taking lens  10  has not reached the wide-end position, the processing returns to the step P 34 , and the same processing as the processing described above is repeated. In cases where it has been judged in the step P 34  that the zoom switch  63  is not operated, in the step P 37 , the zoom driving motor  78  is stopped.  
     [0327] When the zoom driving motor  78  is thus stopped, in cases where the taking lens  10  is in the state in which the zoom magnification ratio falls within the range of 1 to 3, as described above, the zooming position of the finder optical system  430  is such that the zoom magnification ratio may fall within the range of 1 to 3, and the image of the same field angle as the field angle of the image displayed in the finder can be recorded. In cases where the finder optical system  430  is in the state in which the zoom magnification ratio falls within the range of 3 to 6, the zooming position of the taking lens  10  is set at the tele-end position at all times.  
     [0328] Thereafter, in a step P 38 , the zooming position of the taking lens  10  is detected. The detection is carried out by utilizing, for example, an output of a linear encoder for detecting the positions of the zoom lenses.  
     [0329] Thereafter, in a step P 39 , a judgment is made as to whether the correction mode is or is not set, i.e. whether the aforesaid correction flag is or is not on. In cases where it has been judged that correction flag is on, in a step P 40 , reference is made to a correction mode table, which is stored in the table memory  80  shown in FIG. 27, and the processing for calculating the movement distances of the reflector  402  and the strobe flash tube  403  from the optical panel  400  is carried out. In cases where it has been judged that correction flag is not on, in a step P 41 , reference is made to a normal mode table, which is stored in the table memory  80  shown in FIG. 27, and the processing for calculating the movement distances of the reflector  402  and the strobe flash tube  403  from the optical panel  400  is carried out.  
     [0330] Table 1 below shows an example of the correction mode table. Table 2 below shows an example of the normal mode table.

     [0331]               TABLE 2                          [Normal Mode Table]                 [Unit: EV]                                     Center   Top/bottom light quantity   Right/left light quantity   Reflector                                                         Zooming   Light   Top   Top   Bottom   Bottom   Left   Left   Right   Right   movement       Position   Quantity   100%   50%   50%   100%   100%   50%   50%   100%   distance                                                                 Z1   −0.50   −0.30   −0.11   −0.11   −0.30   −0.20   −0.07   −0.07   −0.20   2.0 mm       Z2   −0.80   −0.25   −0.09   −0.09   −0.25   −0.16   −0.06   −0.06   −0.16   2.5 mm       Z3   −1.10   −0.20   −0.07   −0.07   −0.20   −0.12   −0.04   −0.04   −0.12   3.1 mm       Z4   −1.40   −0.15   −0.05   −0.05   −0.15   −0.08   −0.03   −0.03   −0.08   3.7 mm       Z5   −1.70   −0.10   −0.04   −0.04   −0.10   −0.04   −0.01   −0.01   −0.04   4.3 mm       Z6   −2.00   −0.05   −0.02   −0.02   −0.05   0.00   0.00   0.00   0.00   4.9 mm       Z7   −2.30   0.00   0.00   0.00   0.00   0.00   0.00   0.00   0.00   5.5 mm       Z8   −2.60   0.00   0.00   0.00   0.00   0.00   0.00   0.00   0.00   6.1 mm                    
     [0332] When Table 1 and Table 2 are compared with each other, in cases where the zooming position of the taking lens  10  is the same, the movement distances of the reflector  402  and the strobe flash tube  403  from the optical panel  400 , which distances are defined in the correction mode table, are longer than those defined in the normal mode table. Specifically, when the correction mode table is referred to, the light distribution characteristics of the strobe are set such that the decrease in peripheral light quantity may become large and the light throw distance may become long.  
     [0333] Also, when the movement distances described above are calculated, pieces of information representing the center light quantity, the top and bottom light quantities, and the right and left light quantities, which are specified with respect to the movement distances in the table, and the information representing the corresponding frame number are stored in a memory (not shown).  
     [0334] In Tables 1 and 2, a zooming position Z 1  is the wide-end position, and a zooming position Z 8  is the tele-end position. Zooming positions Z 2  through Z 7  are the positions located successively between the wide-end position and the tele-end position.  
     [0335] Thereafter, in a step P 42 , processing for moving the reflector  402  and the strobe flash tube  403  by the movement distances, which have been obtained by making reference to the table in the manner described above, is carried out. The movement is carried out by the reflector driving motor  77  shown in FIG. 27. When the movement has been finished, in a step P 43 , the subroutine processing is finished. Also, the processing returns to the flow shown in FIG. 28.  
     [0336] How the release processing in the step P 25  shown in FIG. 28 is carried out will be described hereinbelow with reference to FIG. 31. As illustrated in FIG. 31, in a step P 50 , the subroutine processing for the release starts. Thereafter, in a step P 51 , a battery check is made. In a step P 52 , a judgment is made as to whether the results of the battery check are or are not good. In cases where it has been judged that the battery does not satisfy predetermined performance, in a step P 53 , the results of the battery check are indicated in the finder. Also, in a step P 62 , the subroutine processing is finished.  
     [0337] In cases where it has been judged that in the step P 52  that the results of the battery check are good, in steps P 54 , P 55 , and P 56 , respectively, distance measurement, photometry, and lens driving processing for the focusing are carried out.  
     [0338] Thereafter, in a step P 57 , a judgment is made as to whether the shutter push button  20  shown in FIG. 25 has or has not reached a predetermined push-down position P 1 . In cases where it has been judged that the shutter push button  20  has not reached the push-down position P 1 , in the step P 62 , the subroutine processing is finished. Also, the processing returns to the flow shown in FIG. 28.  
     [0339] In cases where it has been judged that the shutter push button  20  has reached the push-down position P 1 , in a step P 58 , a judgment is made as to whether the shutter push button  20  has or has not reached a predetermined push-down position P 2 , which is deeper than the push-down position P 1 . In cases where it has been judged that the shutter push button  20  has not reached the push-down position P 2 , the processing returns to the step P 57 . In cases where it has been judged that the shutter push button  20  has reached the push-down position P 2 , in a step P 59 , a release operation is carried out, and the photographing operation is completed.  
     [0340] Thereafter, in a step P 60 , the pieces of information G representing the center light quantity, the top and bottom light quantities, and the right and left light quantities, which have been obtained in the step P 40  or P 41  shown in FIG. 30 and have been stored in the memory (not shown) together with the information representing the corresponding frame number, are transferred to the storage device  54  of the cartridge  53  shown in FIG. 4 and written on it. At this time, information H, which represents the image range of the image displayed by the aforesaid finder optical system  430 , is also written on the storage device  54 .  
     [0341] The writing of the information may be carried out with a contact technique via a contact point or with a non-contact technique.  
     [0342] In a step P 61 , the photographic film  51  is fed by a length corresponding to one frame. Thereafter, in a step P 62 , the subroutine is finished. Also, the processing returns to the flow shown in FIG. 28.  
     [0343] After object images have been recorded in the frames of the photographic film  51  accommodated in the film cartridge  50 , the film cartridge  50  is taken out of the camera body  1  and subjected to the development processing in a processing laboratory, or the like. In this manner, the photographic latent images having been recorded on the photographic film  51  are developed. From the thus formed negative film, photoprints are formed on predetermined recording paper. At this time, processing for compensation for the insufficiency in peripheral light quantity of the strobe and the pseudo zoom processing are carried out in accordance with the pieces of information, which have been stored in the storage device  54 . How the such processing is carried out will hereinbelow be described in detail.  
     [0344] In this embodiment, the photo printing system illustrated in FIG. 7 is utilized.  
     [0345] In the photo printing system, as described above, the image processing apparatus  101  carries out predetermined image processing on the image signal, which has been detected from the developed photographic film  51 A, and transfers the processed image signal to the photo printer  102 . Also, the image processing apparatus  101  records the processed image signal on media  106 , such as CD-R. Further, in this embodiment, the image processing apparatus  101  receives pieces of information G and H, which have been stored in the storage device  54  and have been read by the reading means  103 , from the reading means  103 .  
     [0346] The system constitution of the photo printing system, which is employed in this embodiment, will hereinbelow be described in detail with reference to FIG. 34. In the constitution shown in FIG. 34, functions concerning the image processing may be provided as the functions of the image processing apparatus  101 , or may be incorporated as the functions of the photo printer  102  or the film scanner. Therefore, the constitution shown in FIG. 34 will be described hereinbelow without the correspondence with FIG. 7 being manifested.  
     [0347] As illustrated in FIG. 34, the scanner  110  detects an image signal from the photographic image. The image signal is processed by various image processing means  111 ,  112 ,  413 ,  114 ,  115 , and  116  and is then used in the photo printer  102  for reproducing a photoprint.  
     [0348] The set-up gradation/color processing means  111  automatically makes a judgment as to under-exposure or over-exposure and makes a correction to an appropriate value. The image size enlargement or reduction processing means  112  converts pixel density for matching the size of the printed image to the width of a recording material (e.g., a roll of printing paper) or for carrying out the pseudo zoom processing. An image density correction processing means  413  adjusts the image density, which is represented by the image signal, with respect to each of portions of the image. The graininess suppression type of sharpness enhancement processing means  114  carries out a graininess suppression type of sharpness enhancement processing described in, for example, Japanese Unexamined Patent Publication No. 9 (1997)-22460.  
     [0349] Further, besides a series of image processing described above, color conversion in accordance with characteristics of the printer is carried out on the image signal for print reproduction by the 3D conversion processing means  115  or  116 . The 3D conversion processing varies in accordance with whether the film from which the image signal was obtained is negative film or reversal film.  
     [0350] How the pixel density conversion for the pseudo zoom processing is carried out by the image size enlargement or reduction processing means  112  will be described hereinbelow. The image size enlargement or reduction processing means  112  receives the storage information H of each of frames of the photographic film  51 A from the reading means  103 . As described above, the storage information H represents the image range ratio of the image displayed in the finder to the object image. In accordance with the image range ratio, the image size enlargement or reduction processing means  112  carries out the image size enlargement or reduction processing (pixel density conversion) such that a printed image of the same range as the image displayed in the finder may be obtained.  
     [0351] At this time, as described above, as for the images having been recorded when the finder optical system  430  is set in the state in which the zoom magnification ratio falls within the range of 1 to 3, the field angle is identical with the field angle of the image displayed in the finder. Therefore, as for such images, the relationship between the size of the image recorded on the film and the size of the printed image becomes identical with the relationship shown in FIGS. 9A and 9B. Specifically, in such cases, printing processing is carried out such that an image shown in FIG. 9A, which has been recorded in a certain frame F on the developed photographic film  51 A, may be reproduced on the recording material  200  having a predetermined size as shown in FIG. 9B, such that the image size may not be enlarged or reduced.  
     [0352] As for the images having bee:n recorded when the finder optical system  430  is set in the state in which the zoom ratio falls within the range of 3 to 6, the relationship between the size of the image recorded on the film and the size of the printed image becomes identical with the relationship shown in FIGS. 9A and 9C. Specifically, as for such images, the pseudo zoom processing is carried out.  
     [0353] As described above, with this embodiment of the camera and the photo printing system in accordance with the present invention, even if the taking lens  10  having a zoom ratio of 3 is employed, a photoprint can be obtained as if it were photographed with a taking lens having a zoom ratio of 6.  
     [0354] How the image density correction processing is carried out by the image density correction processing means  413  will be described hereinbelow. The reading means  103  reads the storage information G with respect to each frame from the storage device  54  of the film cartridge  50  and feeds it into the image density correction processing means  413 . When necessary, the image density correction processing means  413  carries out processing on the image signal, which represents the image recorded in the frame, for partially setting the printed image density at a low value such that the insufficiency in peripheral light quantity may be compensated for. Whether the processing is or is not necessary, the range of the correction, and the amount of correction are determined in accordance with a predetermined program and from the center light quantity, the top and bottom light quantities, and the right and left light quantities, which are represented by the storage information G.  
     [0355] In cases where the image density correction processing is carried, even if an image was recorded with the strobe, which was set such that the peripheral light quantity may become small and the light throw distance may become long, a print can be obtained, in which the image density has been corrected over the entire area.  
     [0356] In this embodiment, the printed image density is partially corrected such that the insufficiency in peripheral light quantity of the strobe may be compensated for. However, in cases where an image is recorded by setting the light distribution characteristics of the strobe such that a sufficient peripheral light quantity may be obtained, under-exposure will often occur over the entire image area. With the embodiment of the camera and the photo printing system in accordance with the present invention, such under-exposure can also be compensated for.
