     FIELD OF THE INVENTION 
     The invention relates generally to the field of photography, and in particular to a hybrid film exposure, electronic exposure camera. More specifically, the invention relates to a dual film image capture, electronic image capture camera that is capable of electronic information editing after each substantially simultaneous film and electronic exposure, and that magnetically records the information adjacent each one of the exposed film frames after completed exposure of the entire film length. 
     BACKGROUND OF THE INVENTION 
     Prior art U.S. Pat. No. 5,710,954 issued Jan. 20, 1998 discloses a camera for exposing latent images on successive frames of a filmstrip having magnetic recording capacity, in which an electronic image sensor forms an electronic image corresponding to the latent image on a most-recently exposed one of the film frames substantially simultaneously with exposure of the latent image on that exposed frame, a motor is actuated to incrementally advance the filmstrip forward to permit the each unexposed one of the film frames to be exposed and is actuated after the final available one of the film frames is exposed to rewind the exposed film length rearward, and a magnetic head magnetically records user-selected information on the filmstrip adjacent each exposed frame. 
     The Cross-Referenced Applications 
     The cross-referenced application Ser. No. 09/491,633, entitled DUAL FILM EXPOSURE, ELECTRONIC EXPOSURE CAMERA WITH FILM REWRITE FUNCTION, discloses a camera for exposing latent images on successive frames of a filmstrip having magnetic recording capacity, including a control that actuates a motor following exposure of each film frame to advance the filmstrip forward one frame increment, and a magnetic head that magnetically records user-selected information on the filmstrip adjacent the most-recently exposed one of the film frames as the filmstrip is advanced forward. The control first actuates the motor to advance the filmstrip rearward one frame increment when it is desired to change the existing information magnetically recorded adjacent the most-recently exposed one of the film frames to some new information, and then actuates the motor to advance the filmstrip forward one frame increment for the magnetic head to magnetically record the new information adjacent the same frame in place of the existing information. Preferably, an electronic image sensor is connected to the control to form an electronic image corresponding to the latent image on the most-recently exposed one of the film frames, and a memory is connected to the control to store the electronic image corresponding to the latent image on the most-recently exposed one of the film frames and to store at least some of the magnetically recorded information for the same frame superimposed on the electronic image. 
     The cross-referenced application Ser. No. 09/492,055, entitled DUAL FILM EXPOSURE, ELECTRONIC EXPOSURE CAMERA WITH DELAY IN FILM REWIND AFTER FINAL EXPOSURE TO ALLOW FILM REWRITE, discloses a camera for exposing latent images on successive frames of a filmstrip having magnetic recording capacity, includes a memory that stores a count indicative of the film frames remaining to be exposed (including a count of “0” to indicate that the final frame was exposed), a magnetic head that magnetically records user-selected information on the filmstrip adjacent each film frame, and a motor that is actuated following exposure of each film frame to advance the filmstrip forward one frame increment to permit the magnetic head to record the information on the filmstrip adjacent each exposed frame and that is actuated after the magnetic information is written on the filmstrip adjacent the final exposed frame to rewind the exposed film length rearward. An input receiving control is connected to the memory, the magnetic head, and the motor for delaying actuation of the motor to rewind the exposed film length rearward after the magnetic head has magnetically written the information on the filmstrip adjacent the final exposed frame, to give the user some time to manually input to the control that the information magnetically written adjacent the final exposed frame should be rewritten, and in the absence of the input by the time the delay has elapsed triggers actuation of the motor to rewind the exposed film length rearward. 
     The cross-referenced application Ser. No. 09/491,448, entitled DUAL FILM EXPOSURE, ELECTRONIC EXPOSURE CAMERA WITH MULTIPLE REWRITE ON FILM EXCEPT FOR FINAL EXPOSURE discloses a camera for exposing latent images on successive frames of a filmstrip having magnetic recording capacity, includes a memory that stores a count indicative of the film frames remaining to be exposed (including a count of “0” to indicate that the final frame was exposed), a magnetic head that magnetically records user-selected information on the filmstrip adjacent each film frame, and a motor that is actuated following exposure of each film frame to advance the filmstrip to permit the magnetic head to record the information on the filmstrip adjacent each exposed frame. A plurality of information selection switches can be manually used to select the information the magnetic head will magnetically record on the filmstrip adjacent the most-recently exposed one of the film frames including the final exposed frame. An input receiving control is connected to the memory, the magnetic head, the motor, and the information selection switches to actuate the motor to advance the filmstrip to permit the magnetic head to record the information on the filmstrip adjacent the most-recently exposed one of the film frames except the final exposed frame, each time at least one of the selection switches is used to select the information, and to record the information on the filmstrip adjacent the final exposed frame, only one time at least one of the selection switches is used to select the information. 
     SUMMARY OF THE INVENTION 
     A camera for exposing latent images on successive frames of a filmstrip having magnetic recording capacity, in which an electronic image sensor forms an electronic image corresponding to the latent image on a most-recently exposed one of the film frames substantially simultaneously with exposure of the latent image on that exposed frame, a motor is actuated to incrementally advance the filmstrip forward to permit the each unexposed one of the film frames to be exposed and is actuated after the final available one of the film frames is exposed to rewind the exposed film length rearward, and a magnetic head magnetically records user-selected information on the filmstrip adjacent each exposed frame, is characterized in that: 
     a memory stores the electronic image and the information to be magnetically recorded for every one of the exposed frames; 
     a display can show the electronic image and at least some of the information stored in the memory for any one of the exposed frames; 
     an exposed frame selector can be manually used to change the electronic image and the information shown in the display for any one of the exposed frames to the electronic image and the information stored in the memory for another one of the exposed frames; and 
     a plurality of information selectors can be manually used to change the information stored in the memory for the particular one of the exposed frames that corresponds to the electronic image shown in the display, whereby the information to be magnetically recorded adjacent any one of the exposed frames can be changed before the exposed film length is rewound rearward. 
     Preferably, a control is connected to the motor, the memory and the magnetic head to first actuate the motor after the final available one of the film frames is exposed to rewind the exposed film length rearward, then actuate the motor to continuously advance the exposed film length forward, and finally actuate the motor to rewind the exposed film length rearward. The control causes the magnetic head to magnetically record the information stored in the memory for each exposed frame on the exposed film length when the exposed film length is continuously advanced forward.

     DETAILED DESCRIPTION OF THE INVENTION 
     The invention is disclosed as being embodied preferably in a motorized film advance camera. Because the features of a motorized film advance camera are generally known, the description which follows is directed in particular only to those elements forming part of or cooperating directly with the disclosed embodiment. It is to be understood, however, that other elements may take various forms known to a person of ordinary skill in the art. 
     Referring now to the drawings, FIGS. 1 and 2 show a motorized film advance camera  10  for exposing latent images on successive frames  12  of a known “Advanced Photo System” (“APS”) filmstrip  14 . The filmstrip  14  has a transparent magnetic overlay which gives it magnetic recording capacity to store various user-selected information along a track  16  adjacent each exposed film frame  12 , and it is normally housed in an opaque film cartridge  18 . Typically, the filmstrip  14  is available in 15-exposure, 25-exposure, and 40-exposure lengths, and the user-selected information can differ from frame-to-frame. 
     The camera  10  has an opaque main body part  20  that is housed between a pair of connected opaque front and rear cover parts  22  and  24 . See FIG.  1 . The main body part  20  has a cartridge receiving chamber  26  for receiving the film cartridge  18  through a bottom opening (not shown) when a bottom door  28  is pivoted open, a rearwardly open backframe opening  30  at which the respective frames  12  of the filmstrip  14  are temporarily positioned one at a time to be exposed, and an exposed film take-up chamber  32  that contains a film take-up spool  34  which is incrementally rotated following each film exposure to wind the most-recently exposed one of the film frames onto an exposed film roll  36  on the spool (and to position a fresh unexposed film frame at the backframe opening  30 ). When the film take-up spool  34  is incrementally rotated, the filmstrip  14  is advanced forward one frame increment which is slightly greater than a frame width. A drive motor  38  resides inside the film take-up spool  34  for incrementally rotating the spool to advance the filmstrip  14  forward one frame increment, and its operation is controlled by a known microcomputer  40 . When substantially the entire length of the filmstrip  14  is exposed, i.e. the total number of available frames  12  are exposed, a spindle (not shown) which projects into a cavity  42  in a top end  44  of a film spool inside the film cartridge  18  is continuously rotated via the motor  38  and a suitable gear train (not shown) to rewind the exposed film length rearward into the cartridge. 
     To magnetically record the user-selected information along the track  16  adjacent each exposed film frame  12 , the motor  38  must be actuated after the exposed film length is rewound rearward into the film cartridge  18  to continuously rotate the film take-up spool  34  in order to advance the exposed film length forward. Then, the motor  38  is actuated to continuously rotate the film spool inside the film cartridge  18  in order to rewind the film length with the recorded information rearward into the cartridge, and the door  28  is pivoted open to remove the cartridge from the cartridge receiving chamber  26 . 
     A known electronic flash unit  46  for flash assisted exposures is flipped up from partially covering the front cover part  22  to uncover a taking lens (not shown) preparatory to using the camera  10 . See FIG.  1 . Flipping up the flash unit  46  closes a normally open power switch  48  connected to the microcomputer  40  to electrically power “on” the camera  10 . See FIG.  2 . 
     A normally open cartridge present switch  50  in the cartridge receiving chamber  26  and connected to the microcomputer  40  is closed when the film cartridge  18  is present in the chamber and the door  28  is closed. See FIG.  2 . If the camera  10  is powered “on” and the cartridge present switch  50  is open, a visible no-cartridge warning  52  shown in FIG. 3 is shown in a known status display  54  such as a black and white LCD connected to the microcomputer  40 . The status display  54  is turned “on” when the power switch  48  is closed, and is located behind a window  56  in the rear cover part  24 . See FIG.  1 . If the camera  10  is powered “on” and the cartridge present switch  50  is closed, a visible cartridge loaded indication (not shown) is shown in the status display  54  A known electronic image sensor  58 , for example a CCD sensor with integrated shuttering capability or a CMOS sensor with integrated shuttering capability, is connected to the microcomputer  40  to form a different electronic image each time one of the unexposed film frames  12  is exposed. The respective electronic images correspond to the latent images on the exposed film frames  12 , are each stored in a memory  60  connected to the microcomputer  40 , and can be shown one at a time in a known image display  62  such as a color LCD connected to the microcomputer. The image display  62  is located next to the status display  54 , behind the window  56  in the rear cover part  24 . The memory  60  has storage capacity for storing at least  40  electronic images, since the filmstrip  14  is available in 15-exposure, 25-exposure, and 40-exposure lengths. 
     A viewfinder  64  for viewing a subject to be photographed is located on the main body part  20 . See FIG.  1 . 
     To take a picture, a shutter release button  66  on the front cover part  22  is manually depressed which in turn closes a normally open release switch  68  connected to the microcomputer  40 . See FIGS. 1 and 2. The closed switch  68  triggers momentary opening of a known normally closed shutter  70  to expose a latent image on the film frame  12  at the backframe opening  30 , and to excite the electronic image sensor  58  to form an electronic image substantially simultaneously with exposure of the latent image. The taking lens (not shown) can be used to focus an image of the subject being photographed, for the electronic image sensor  58  as well as for the filmstrip  14 , or a separate lens an be provided for the electronic image sensor. These alternatives are indicated in prior art U.S. Pat. No. 5,710,954 issued Jan. 20, 1998. 
     A magnetic head  72  is mounted within an opening  74  in a film pressure platen  76  for magnetically recording the user-selected information along the track  16  adjacent each one of the exposed film frames  12 . The film pressure platen  76  serves to support each film frame  12  flat for exposure at the backframe opening  30 . 
     The user-selected information, as is known, can be a selected print quantity, a selected (optional) print title, a selected (optional) print exposure correction +/−, and a selected “APS” print format “C” (classic), “H” (HDTV) or “P” (panoramic), for example. A “C” format print is usually 4×6 inches, a wider “H” format print is often 4×7 inches, and a much wider “P” format print is either 4×10 inches or 4×11.5 inches. The selected print quantity, print title, and print exposure correction, and the selected “APS” print formats “C”, “H” or “P”, for every one of the exposed film frames  12  are stored in the memory  60 . Individual visible indications of the selected print quantity, print title, and print exposure correction for any one of the exposed film frames  12  can be seen in the status display  54 . A visible indication of the selected “APS” print format “C”, “H” or “P” for any one of the exposed film frames  12  can be seen in the image display  62  (preferably superimposed on the electronic image shown in the image display). Respective print quantity, title and exposure correction buttons  78 ,  80  and  82  are provided on the rear cover part  24 , and when individually manually depressed one or more times close normally open print quantity, title and exposure correction switches  84 ,  86  and  88  the same number of times. See FIGS. 1 and 2. The print quantity, title and exposure correction switches  84 ,  86  and  88  are connected to the microcomputer  40  in order to change the print quantity, title and exposure correction stored in the memory  60  for any one of the exposed film frames  12  to new selections for the same exposed film frame. A format selection button  90  is provided on a top plate  92 , and when manually depressed one or more times closes a normally open C, H, P switch  94  the same number of times. The C, H, P switch  94  is connected to the microcomputer  40  in order to change the C, H or P selection stored in the memory  60  for any one of the exposed film frames  12  to a new selection for the same exposed film frame. To enter the newly selected information in the memory  60 , an enter button  96  on the rear cover part  24  must be manually depressed which in turn closes a normally open enter switch  98  connected to the microcomputer  40 . 
     An exposed frame selector button  100  is provided on the rear cover part  24 , and when manually depressed one or more times closes a normally open exposed frame selector switch  102  the same number of times to change the electronic image and the “APS” print format “C”, “H” or “P” shown in the image display  62  for any one of the exposed film frames  12 , and to change the print quantity, print title, and print exposure correction shown in the status display  54  for the same exposed film frame, to the electronic image and the user-selected information for another one of the exposed film frames. This is possible because the electronic images that match the exposed film frames, and the user-selected information for the exposed film frames, are stored in the memory  60 . Thus, one can effectively scroll through the electronic images and the user-selected information stored in the memory  60  for the exposed film frames  12 , and successively see the electronic images and the user-selected information for any one of the exposed film frames in the status and image displays  54  and  62 . This is done in preparation for manually depressing the print quantity, title and exposure correction buttons  78 ,  80  and  82  and the format selection button  90  to change the user-selected information stored in the memory for any one of the exposed film frames  12 . 
     A pair of identical film perforation sensors  104  and  106  for sensing successive pairs of film perforations  108  and  110  in the filmstrip  14  are mounted in respective pockets  112  and  114  in the film pressure platen  76  and are connected to the microcomputer  40 . The film perforation sensors  104  and  106 , as is known, are used via the microcomputer  40  to decrement a frame count stored in the memory  60  by “ 1 ”, each time the filmstrip  14  is advanced forward a frame increment and the most-recently exposed one of the film frames  12  is wound onto the exposed film roll  36  on the film take-up spool  34 . The frame count begins with “15”, “25” or “40” depending whether the filmstrip  40  has a 15-exposure, 25-exposure, or 40-exposure length. 
     A verify (print preview) button  116  is provided on the rear cover part  24 , and when manually depressed closes a normally open verify switch  118  connected to the microcomputer  40 . See FIGS. 1 and 2. The closed verify switch  118  causes the electronic image and the “APS” print format “C”, “H” or “P” stored in the memory  60  for the most-recently exposed one of the film frames  12  to be shown in the image display  62 , and it causes the print quantity, print title, and print exposure correction stored in the memory for the same exposed film frame to be shown in the status display  54 . If, however the exposed frame selector switch  102  had been closed to change the electronic image and the “APS” print format “C”, “H” or “P” shown in the image display  62  and to change the print quantity, print title, and print exposure correction shown in the status display  54 , from that for the most-recently exposed one of the film frames to that for an earlier exposed one of the film frames, then the closed verify switch  118  causes the electronic image and the user-selected information for the earlier exposed film frame to be shown in the displays. 
     Operation 
     The operation of the camera  10  to illustrate the invention is shown in a flow chart in FIGS. 3-5. 
     1. Starting at FIG. 3, when the camera  10  is electrically powered “on” by flipping up the electronic flash unit  46 , the status display  54  is simultaneously turned “on.” The status display  54  shows, among other things, the frame count stored in the memory  60 . 
     2. If then in FIG. 3 the cartridge present switch  50  remains open because no film cartridge  18  is present in the cartridge receiving chamber  26 , the no-cartridge warning  52  is provided in the status display  54 . 
     3. If conversely in FIG. 3 the cartridge present switch  50  is closed because the film cartridge  18  is present in the cartridge receiving chamber  26 , the memory  60  is interrogated to determine whether the frame count is greater than “0”. 
     4. If then in FIG. 3 the frame count in the memory  60  is “0”, which indicates that the final available one of the film frames  12  has been exposed, i.e. there are no film frames remaining for exposure, the number “0” appears in the status indicator  54 . 
     5. If conversely in FIG. 3 the frame count in the memory  60  is greater than “0”, for example “23”, which indicates that there are twenty-three film frames  12  available for exposure, the number “23” appears in the status indicator  54 . 
     6. If next in FIG. 3 the verify switch  118  is closed, the image display  62  is turned “on” in FIG. 4 to show the electronic image stored in the memory  60  corresponding to the latent image on the most-recently exposed one (or alternatively an earlier exposed one) of the film frames  12 . Also, the status display  54  now shows the user-selected information stored in the memory  60  for the same exposed film frame, except that the visible indication of the selected “APS” print format “C”, “H” or “P” is shown in the image display  62  superimposed on the electronic image. 
     7. If conversely in FIG. 3, the verify switch  118  remains open, and the release switch  68  is not closed within an allotted time, e.g. 150 seconds, determined by a timer  120  in the microcomputer  40 , the camera  10  is powered “off” for battery consumption. 
     8. If conversely in FIG. 3, the verify switch  118  remains open, and the release switch  68  is closed within the allotted time, e.g. 150 seconds, determined by the timer  120  in the microcomputer  40 , because a picture is being taken, a latent image is exposed on the film frame  12  at the backframe opening  30  and the electronic image sensor  58  is excited to form an electronic image which matches the latent image on the newly exposed frame. 
     9. Then in FIG. 4 the motor  38  is actuated to incrementally rotate the film take-up spool  34  in order to advance the filmstrip  14  forward a frame increment and wind the most-recently exposed one of the film frames  12  onto the exposed film roll  36  on the spool. Also, the electronic image and the user-selected information for the most-recently exposed frame  12  are stored in the memory  60 , and the frame count stored in the memory is decremented by “1”, for example to “22.” 
     10. If next in FIG. 4 the frame count in the memory  60  is greater than “0”, the verify switch  114  can be closed. 
     11. If then in FIG. 4 the verify switch  118  is not closed within the allotted time, e.g. 150 seconds, determined by the timer  120  in the microcomputer  40 , or alternatively the release switch  68  is not closed within the same time, the camera  10  is powered “off” for battery consumption. 
     12. If conversely in FIG. 4 the verify switch  118  is closed within the allotted time (as in FIG.  3 ), e.g. 150 seconds, determined by the timer  120  in the microcomputer  40 , the image display  62  is turned “on” to show the electronic image stored in the memory  60  corresponding to the latent image on the most recently exposed one (or alternatively an earlier exposed one) of the film frames  12 . Also, the status display  54  now shows the user-selected information for the same exposed film frame, except that the visible indication of the selected “APS” print format “C”, “H” or “P” is shown in the image display  62  superimposed on the electronic image. 
     13. If next in FIG. 4 the exposed frame selector switch  102  is not closed within the allotted time, e.g. 150 seconds, determined by a timer  120  in the microcomputer  40 , and none of the user-selected information switches  84 ,  86 ,  88  and  94  are closed within a brief time, e.g. 10 seconds, determined by the timer, the image display  62  is turned “off”. The camera  10  including the status display  54  remains “on.” 
     14. If conversely in FIG. 4 the exposed frame selector switch  102  is not closed within the allotted time, e.g. 150 seconds, determined by the timer  120  in the microcomputer  40 , and at least one of the user-selected information switches  84 ,  86 ,  88  and  94  is closed within the brief time, e.g. 10 seconds, determined by the timer, then when the enter switch  98  is closed, the image display  62  is turned “off”, and the electronic image and the new selected information for the most-recently exposed one of the film frames  12  are stored in the memory  60  in place of the previously stored information for the same exposed film frame. 
     15. If alternatively in FIG. 4 the exposed frame selector switch  102  is closed within the allotted time, e.g. 150 seconds, the electronic image and the user-selected information stored in the memory  60  for any one of the earlier exposed film frames (not the most-recently exposed film frame) are shown in the status and image displays  54  and  62  in place of the previously shown image and information for another one of the exposed film frames. Then, when at least one of the user-selected information switches  84 ,  86 ,  88  and  94  is closed within the brief time, e.g. 10 seconds, and the enter switch  98  is closed, the image display  62  is turned “off”, and the electronic image and the new selected information for the earlier exposed film frame  12  are stored in the memory  60  in place of the previously stored information for the same exposed film frame. 
     16. If in FIG. 4 the frame count in the memory  60  is “0”, the image display  62  is turned “on” to show the electronic image stored in the memory  60  corresponding to the latent image on the final exposed one of the film frames  12 . Also, the status display  54  now shows the user-selected information for the same exposed film frame, except that the visible indication of the selected “APS” print format “C”, “U” or “P” is shown in the image display  62  superimposed on the electronic image. The image display  62  is turned “on” in this instance (as compared with the other instance in FIG. 4 that it is turned “on”) without having to first close the verify switch  118 . 
     17. If next in FIG. 4, the exposed frame selector switch  102  is not closed within the allotted time, e.g. 150 seconds, and none of the user-selected information switches  84 ,  86 ,  88  and  94  are closed within a brief time, e.g. 10 seconds, the image display is turned “off” as indicated in FIG. 5, and the motor  38  is actuated to continuously rotate the film spool inside the film cartridge  18  in order to rewind the exposed film length rearward into the cartridge. Then, the motor  38  is actuated to continuously rotate the film take-up spool  34  in order to advance the exposed film length forward, and the magnetic head  72  magnetically records the user-selected information stored in the memory  60  for each exposed film frame on the exposed film length along the track  16  adjacent each exposed film frame. Then, the motor  38  is actuated to continuously rotate the film spool inside the film cartridge  18  in order to rewind the exposed film length rearward into the cartridge. Finally, the door  28  is pivoted open to remove the film cartridge  18  from the cartridge receiving chamber  26 . 
     18. If conversely in FIG. 4 the exposed frame selector switch  102  is not closed within the allotted time, e.g. 150 seconds, and at least one of the user-selected information switches  84 ,  86 ,  88  and  94  is closed within the brief time, e.g. 10 seconds, the image display  62  remains “on.” Then when the enter switch  98  is closed and the verify switch  118  is not closed within the allotted time, e.g. 150 seconds, the image display  62  is turned “off” as indicated in FIG. 5, and the motor  38  is actuated to continuously rotate the film spool inside the film cartridge  18  in order to rewind the exposed film length rearward into the cartridge. Then, the motor  38  is actuated to continuously rotate the film take-up spool  34  in order to advance the exposed film length forward, and the magnetic head  72  magnetically records the user-selected information stored in the memory  60  for each exposed film frame on the exposed film length along the track  16  adjacent each exposed film frame. Then, the motor  38  is actuated to continuously rotate the film spool inside the film cartridge  18  in order to rewind the exposed film length rearward into the cartridge. Finally, the door  28  is pivoted open to remove the film cartridge  18 . 
     19. If alternatively in FIG. 4 the exposed frame selector switch  102  is closed within the allotted time, e.g. 150 seconds, the electronic image and the user-selected information stored in the memory  60  for any one of the earlier exposed film frames (not the most-recently exposed film frame) is shown in the status and image displays  54  and  62 . Then, when at least one of the user-selected information switches  84 ,  86 ,  88  and  94  is closed within the brief time, e.g. 10 seconds, and the enter switch  98  is closed, and the verify switch  118  is not closed within the allotted time, e.g. 150 seconds, the image display  62  is turned “off” as indicated in FIG. 5, and the motor  38  is actuated to continuously rotate the film spool inside the film cartridge  18  in order to rewind the exposed film length rearward into the cartridge. Then, the motor  38  is actuated to continuously rotate the film take-up spool  34  in order to advance the exposed film length forward, and the magnetic head  72  magnetically records the user-selected information stored in the memory  60  for each exposed film frame on the exposed film length along the track  16  adjacent each exposed film frame. Then, the motor  38  is actuated to continuously rotate the film spool inside the film cartridge  18  in order to rewind the exposed film length rearward into the cartridge. Finally, the door  28  is pivoted open to remove the film cartridge  18 . 
     20. If conversely in FIG. 4 the verify switch  118  is closed within the allotted time, e.g. 150 seconds, go back to step  17  above. 
     The invention has been described with reference to a preferred embodiment. However, it will be appreciated that variations and modifications can be effected by a person of ordinary skill in the art without departing from the scope of the invention. For example, when in FIG. 4 the enter switch  98  is not closed within an allotted time, e.g. 150 seconds, determined by the timer  120  in the microcomputer  40 , and alternatively the release switch  68  is not closed within the same time, the camera  10  could be powered “off” for battery consumption.
