Title: Image delivery apparatus

Description:
FIELD OF THE INVENTION  
      The present invention relates to an information-recording medium in which an electronic album that effectively displays image information provided by a customer is recorded, and a method producing the same.  
     TECHNICAL BACKGROUND  
      In recent years, customers who handle photographs taken by a camera as digital image data are increasing. For example, regarding digital cameras, image data stored in an information-recording medium is read by a terminal such as a PC (personal computer), and reproduced with image-display software installed on the PC, which allows viewing photographs easily.  
      Further, conversion services from photographs taken with a film camera into digital image data are carried out. For example, when a customer brings a photographed film to a photo-service shop such as a processing laboratory or an order shop, which handles photo services, in various retail stores (such as a convenience store, a drug store, a department store, a large scale retail shop, etc. hereinafter referred to as retail shops), then the photo-service shop or the order shop provides such services as to develop the film, then read the negative film with a scanner or the like, and write the read image data into an information-recording medium such as a CD-R. Further, customers who use a digital camera as described above desire to backup the information-recording medium, in which the image data photographed by a digital camera is recorded, into another image-recording medium such as a CD-R, while order shops also provide surrogate services for that.  
      A customer who has received an information-recording medium, such as a CD-R in which image data is written, reproduces the image data by the use of a terminal such as a PC at home to enable viewing the photographic images, and even a customer possessing no digital camera can handle photographs as digital image data.  
      However, in the above conventional data conversion service, the aggregation of image data read from photographs of a film or image data photographed by a digital camera is merely written in an information-recording medium, and the operation of displaying the image data is required on the customer side, which only allows viewing photographs individually, resulting in a problem of not enjoying a series of image data as in an album.  
      To enjoy an aggregation of image data as an album, there are methods for displaying the image data continuously, using electronic album software or slide show software installed on a PC, and it is possible to effectively display each image data by the use of slide effects, but, in this case also, the image data are merely displayed in a sequential order designated by the customer, having a low value as an album.  
      Particularly, in the case when a customer gives photographic images photographed by the customer to an acquaintance or a friend as digital data, if electronic album software or slide show software is not installed on the PC of another customer having received the image data, the image data cannot be displayed as an album, and even if this kind of software is installed, displaying the image data merely in a locked-in order does not allow enjoying an album.  
      On the other hand, in recent years, musical-and-vocal information has been handled as digital data, and functions capable of reproducing musical-and-vocal data have also been added to PCs to allow enough enjoyment of music even with a PC. Accordingly, software for reproducing musical-and-vocal data as BGM (back ground music) of a slide show is provided, but, in the case of conventional software, there is no correlation between the image data and the musical-and-vocal data, and BGM is merely played without increasing value to a slide show.  
      Further, although some of the electronic album software or the slide show software described above performs an array-display of index images (thumb-nail images) of image data, when image data obtained from a plurality of films are displayed, the image data are only sequentially lined up, resulting in a problem of not allowing easy identification as to from which film or medium the respective image data have been obtained.  
      The present invention has been devised, taking this problem into account, wherein a primary object thereof is to provide an information-recording medium in which an electronic album capable of effectively reproducing image data and musical-and vocal data are recorded, and to provide a slide show execution program.  
      A secondary object of the invention is to provide an information-recording medium in which an electronic album capable of effectively displaying image data is recorded, and a method of producing the same.

     BEST MODE FOR PRACTICING THE INVENTION  
      In a preferable mode of practicing the invention, on an information-recording medium according to the invention, a computer-readable set of image data provided by a customer, musical-and-voice data selected by the customer at an order shop in a retail store or the like, and a computer program for reproducing the image data and the musical-and-vocal data, correlating them with each other, is recorded; an indication is printed on the surface of the information-recording medium or the jacket of a storage case so that the recorded image data and musical-and-vocal data can be identified; and, in displaying the image data in an image display region for displaying an index image data (thumbnail image data) in an array, the image data are displayed on a sheet provided with a tag that clearly indicates the type of a photographic recording medium (a undeveloped negative film, a memory card, a CD-R, a digital camera, etc.) provided by the customer and the content of the photographic recording medium. Therefore, selectability of image data is extremely enhanced by using tags.  
     EMBODIMENTS  
      To explain the abovementioned mode of practicing the invention with further details, some embodiments of the invention will now be described, referring to the drawings.  
     Embodiment 1  
      First, an information-recording medium in which an electronic album according to a first embodiment of the invention is recorded, and a slide show execution program, will be described, referring to  FIGS. 1 through 13 .  FIG. 1  is a diagram showing a structure of an electronic album ordering system according to the first embodiment of the invention, and  FIG. 2  is a flowchart showing an ordering procedure of an electronic album.  FIG. 3  is a block diagram showing means that function by an electronic album reproduction program (a slide show execution program), and  FIG. 4  is a flowchart showing the processing procedure of the program. FIGS.  5  to  13  are diagrams showing examples of screen structures displayed by the program. A slide show performed according to the invention sequentially displays each image data recorded in the information-recording medium as static images, excluding forms in which image data are continuously displayed as a dynamic image as in the case of a video movie.  
      As shown in  FIG. 1 , electronic album ordering system  1  of the present embodiment is implemented by: customer  2  who provides image data; an order shop in retail store  3  or the like who places an order of an electronic album, selects musical-and-vocal data to be reproduced in synchronization with the image data, and returns developed negative film  2   c  to the customer; and laboratory  4  which receives the image data and designation information for musical-and-vocal data from the retail store  3 , writes the image data, the musical-and-vocal data, and the electronic reproduction program in a set in information-recording medium  5  such as a CD-R in a computer-readable state, and thus produces an electronic album. The laboratory  4  is provided with a developing device  4   a  for developing the undeveloped negative film  2   a  provided by the customer  2 , reading device  4   b  that reads the developed photographs and converts them into digital data, and a writing device  4   c  for writing data and computer programs in the information-recording medium  5 . The respective devices stated above may be arranged separately, and it is also allowed to make an integral arrangement of a pair of the developing device  4   a  and the reading device  4   b,  a pair of the reading device  4   b  and the writing device  4   c,  or a set of the developing device  4   a,  the reading device  4   b,  and the writing device  4   c.  Further, a printer may be provided for producing common prints based on image data read by the reading device  4   b.  There is no particular limitation on the type of printer, allowing it to use an inkjet type, an electrophotographic type, a silver halide type, and others.  
      In the following description, although a description will be made, taking the case of ordering an electronic album at retail store  3 , the order shop is not limited to the retail store  3 , and can be any arbitrary shop which receives orders for developing of films and printing. As for the customer  2 , a case of providing image data as undeveloped negative film  2   a  will be mainly described, but it is also possible to provide a developed negative film, a positive film (developed or undeveloped), information-recording media including memory cards such as a CompactFlash®, a SmartMedia, a MemoryStick®, a MultiMediaCard, a SDMemoryCard, or a CD-R (hereinafter, wall will be referred to merely as an information-recording medium), in which image data obtained from prints or a digital camera is recorded.  
      Referring to a flowchart in  FIG. 2 , it will be described on the procedure, of the electronic album ordering system  1  arranged as above, from the time the customer  2  provides image data to the time the customer  2  obtains information-recording medium  5  in which an electronic album has been recorded.  
      First, in step S 101 , the customer  2  brings undeveloped negative film  2   a  having been photographed with a film camera into an order shop in retail store  3  or the like. Photographic images recorded in this undeveloped negative film  2   a  may, of course, be the customer&#39;s own photography or another customer&#39;s. Further, the image data is not limited to photographic images obtained by photographing with a camera, but may be image data obtained through communication networks such as the Internet or image data having been processed by the customer, using image processing software.  
      Next, in step S 102 , the customer  2  places an order of an electronic album at counter  3   a,  and writes information for identifying the customer  2  and additional information such as a message or the like to be displayed together with the image data, if necessary, in order sheet  2   b  in a predetermined format. When the customer  2  brings in undeveloped negative film  2   a,  all the photographs recorded in the undeveloped negative film  2   a  are usually used for the electronic album, but when the customer  2  brings in a developed negative film or an information-recording medium, it is possible to use only a part of the recorded photographs. In case when the customer  2  performs selection of image data in step S 103 , the customer  2  selects image data to be used for the electronic album, designating exposure numbers of the developed negative film or file names in the information-recording medium.  
      Next, in step S 105 , the customer  2  selects musical-and-vocal data to be played as BGM of a slide show. In the present embodiment, musical-and-vocal data is stored in the laboratory  4 , and the retail store  3  prepares a list of available musical-and-vocal data at the counter  3   a  so that the customer  2  designates desired musical pieces from the list. The musical-and-vocal data is not limited to that prepared in the retail store  3 , and the customer  2  may bring and provide musical-and-vocal data in a predetermined format, or use musical-and-vocal data that the customer  2  has made himself/herself as BGM.  
      Then, in step S 106 , the retail store  3  sends the undeveloped negative film  2   a  that the customer  2  has brought in, designation information on the musical-and-vocal data that the customer  2  selected, together with the order sheet  2   b  to the laboratory  4 . As a method of sending these to the laboratory  4 , when the photographic images are provided as undeveloped negative film  2   a,  the undeveloped negative film  2   a,  the designation information on the musical-and-vocal data, and the order sheet  2   b  may be sent to the laboratory  4  by post mail, or a collection and delivery service, and when the photographic images are provided as digital data, the image data, the designation information on the musical-and-vocal data, and information on the order sheet may be transmitted via the Internet or communication networks such as a private line.  
      Then, the laboratory  4  which has received the undeveloped negative film  2   a,  the designation information on the musical-and-vocal data, and the order sheet  2   b,  makes an electronic album provided with an electronic album reproduction program (specific functions and operations of which will be described later) including a slide show execution program therein that synchronizes the image data with the musical-and-vocal data and displays/plays them, which is a characteristic of the invention. In this situation, when the image data is received as the undeveloped negative film  2   a  in step S 107 , the developing device  4   a  is used to develop the negative film, and the negative film is converted into digital data, using the reading device  4   b  such as a scanner or the like. When the image data is received as a developed negative film, the negative film is converted into digital data, using the reading device  4   b.    
      Then, in step S 108 , the image data read by the reading device  4   b  or the image data recorded in an information-recording medium, the designated musical-and-vocal data, and the electronic album reproduction program are written in the information-recording medium  5  such as a CD-R in a computer readable state to make the electric album. If the customer  2  has added a message to be displayed together with the image data, the additional information is also written in the information-recording medium  5 . The information-recording medium is not limited to a CD-R, but any medium readable by a terminal such as a PC may be used, including a DVD-R, MO, etc., and, a CD-R is most preferable because it is computer readable and inexpensive.  
      Next, in step S 110 , the laboratory  4  sends the information-recording medium  5  in which the image data, the musical-and-vocal data, and the electronic album reproduction program are recorded, and the developed negative film  2   c,  to the retail store  3 , and then, in step S 110 , the retail store  3  provides them to the customer  2 .  
      As stated above, an electronic album produced by the system of the present embodiment is different from an electronic album provided with conventional slide show functions, in that, in addition to image data and musical-and vocal data to be played as BGM, an electronic album reproduction program for displaying/playing of the image data and the musical-and-vocal data, correlating them with each other, is computer readably recorded in the information-recording medium  5 . Therefore, the customer  2  can enjoy a slide show reproduced with the integration of the image data and the musical-and-vocal data just by inserting the information-recording medium  5  into a PC or the like.  
      Referring to FIGS.  3  to  13 , functions and operations of the electronic album reproduction program, and the slide show execution program of the present embodiment, will be now described below.  
      As shown in  FIG. 3 , the electronic album reproduction program of the present embodiment functions as: album displaying means  6   a  for displaying a plurality of image data, provided by the customer  2 , being compressed in an album form; image data processing means  6   b  for various image processing on each individual image data; data storage means  6   c  for recording designated image data and musical-and-vocal data on a hard disk or another type of information-recording medium; electronic mail means  6   d  for transmitting an electronic mail with designated image data as an attached file; image data printing means  6   e  for printing out designated image data; uploading means  6   f  for uploading designated image data onto a server; slide show displaying means  6   g  for displaying image data and musical-and-vocal data, correlating them with each other, in a slide displaying mode; slide effect setting means  6   h  for setting slide effects; musical-and-vocal data analysis program  6   i  for analyzing musical-and-vocal data to adjust display timing of image data; and image data analysis program  6   j  for analyzing image data, extracting characteristics thereof, and selecting musical-and-vocal data suitable for the image data.  
      The electronic album reproduction program of the present embodiment is not required to cause a computer to function as all of these means, wherein the electronic album reproduction program, to be used as a slide show execution program, is required, as a minimum requirement, to cause the computer to function as the slide show displaying means  6   g,  the slide effect setting means  6   h,  and the musical-and-vocal data analysis program  6   i,  and it is also allowed to arrange the electronic album reproduction program to cause the computer to function as other known means.  
      The operations of the electronic album reproduction program and the slide show execution program will be described below, referring to the flowchart in  FIG. 4  and the examples of screen structures in FIGS.  5  to  13 .  
      First, in step S 201 , when the customer  2  inserts the information-recording medium  5  in which an electronic album of the present embodiment is recorded, into a terminal such as a PC, the electronic album reproduction program automatically starts, and menu screen  7  as shown in  FIG. 5  is displayed. The menu screen  7  displays, for example, image data groups  8  (three image data groups are displayed in the figure.) each of which is an aggregation of individual exposure image data  8   a  of undeveloped negative film  2   a,  and switches  9  to  14  that clearly indicate processes to be performed on a selected image data group  8  and individual exposure image data  8   a.  On each image data group  8  and individual exposure image data  8   a,  numbers that include a date of photography or an order date, and a sequential serial number are described to enable identification of each image data group  8  and individual exposure image data  8   a.    
      Then, in step S 202 , when the customer  2  selects a desired image data group  8  from the image data groups  8 , an album of the individual exposure image data  8   a  of the selected image data group  8  is displayed, wherein the individual exposure image data  8   a  are arranged in a reduced layout. Although the album has a layout in  5  rows in  FIG. 5 , the layout format of the album is not limited to the arrangement shown in the figure, and the number of display can be increased or decreased, by reducing or enlarging the size of individual exposure image data  8   a  depending on the desire of the customer  2 .  
      Next, in step S 203 , the customer  2  selects a process to be performed on the displayed image data group  8  and individual exposure image data  8   a,  and clicks a corresponding one of the switches  9  to  14  by a mouse. In the present embodiment, as processes to be performed on image data, although  6  processes, that is, image processing, storing, electronic mailing, printing, uploading, and slide show, are shown, the illustration in the figure is only examples, and other processes not described above may also be performed, as well as allowing omission of processes except the slide show. In the following description, the content of each process will be described in the order shown in the illustration. It will be described here on the case where, when the electronic album reproduction program starts, the menu screen  7  automatically starts, but the operation may be arranged such that the slide show execution program directly starts when the information-recording medium  5  is inserted, and a menu program starts when an arbitrary key or a designated key is pressed, or overall reproduction is terminated.  
      With some cameras for photographing on a film, photography is performed starting from the last exposure after the roll of film is wound up, and in the case of an image data group  8  having been produced by scanning of a negative film on which photography has been performed with such a camera, individual exposure image data  8   a  are displayed in the sequential order starting from the last photographed image. Since it is usually preferable that images are in the order starting form older ones in a time series, the order of displaying the images needs to be reversed. In this case, when a reverse order display icon  29  is pressed, the icon being an information input icon for reversing the order of displaying of images to be displayed in a slide displaying mode, the images are displayed again in a reversed order so that the images are displayed starting from the exposure having been photographed first in terms of time.  
      (Image Processing)  
      When, for example, an individual exposure image data  8   a  is selected from an image data group  8 , and thereafter “Image Processing” is selected in step S 203 , then image processing screen  15 , as shown in  FIG. 6 , is displayed in step S 204 . The image processing screen  15  displays, for example, an individual exposure image data display region  16  for an original sized or enlarged display of the selected individual exposure image data  8   a,  switches  17  to  21  for performing various image processing, a “Store” switch  22 , a “Print” switch  23 , and a “Cancel” switch  24  for returning to the menu screen  7 .  
      For example, in case of adjusting the brightness of the exposure image data Ba in step S 205 , when “Brightness Adjust” switch  17  is pressed, then brightness adjustment screen  17   a,  as shown in  FIG. 7 , is superimposed on the image processing screen  15 , and thus displayed. This brightness adjustment screen  17   a,  for example, displays a region to display original image data, a region to display image data having been adjusted, a brightness adjustment section, and a region to display the brightness degree of each pixel of the image data, in histogram form, wherein the customer  2  can adjust the image data to a desired brightness by operating the brightness adjustment section while confirming the image having been adjusted and the histogram (step S 206 ).  
      Further, in case of adjusting the color of the exposure image data  8   a  in step S 205 , when “Color Adjustment” switch  19  is pressed, color adjustment screen  19   a  as shown in  FIG. 8  is superimposed on the image processing screen  15 , and thus displayed. This color adjustment screen  19   a  displays, for example, a region to display the original image data, a region to display image data having been adjusted, and a color adjustment section of the respective colors RGB, wherein the customer  2  can adjust the image data to desired colors by operating the color adjustment section of the respective colors RGB while confirming the image which has been adjusted.  
      (Storing)  
      When an individual exposure image data  8   a  is selected from an image data group  8 , and thereafter “Storing” is selected in step S 203 , a screen (not shown) to select a directory to be a storage destination is displayed on the menu screen  7 , and when the customer  2  designates a storage destination of the image data, such as a hard disk, in step S 207 , then the selected image data is stored in the designated directory (step S 208 ).  
      (Electronic Mail)  
      When an individual exposure image data  8   a  is selected from an image data group  8 , and thereafter “Electronic Mail” is selected in step S 203 , image size designation screen  11   a,  as shown in  FIG. 9 , is displayed on the menu screen  7 . The image size designation screen  11   a  is arranged such that, for example, the size (for example, a VGA size or an original image size) of the image data to be attached to an electronic mail can be selected, and when the customer  2  designates a desired image size and presses “Next”, in step S 209 , electronic mail producing screen  11   b,  as shown in  FIG. 10 , is displayed on the menu screen  7 . This electronic mail producing screen lib displays, for example, a region to input the title, the address, broadcast mailing, etc. of the electronic mail, a region to input the text of the mail, and a region to indicate the file name of the attached individual exposure image data  8   a.  When an address, text, etc. are input in steps S 210  and S 211  and a “Mail Send” switch is pressed, the electronic mail attached with the selected image data is sent to the designated address (step S 212 ).  
      (Print)  
      When an individual exposure image data  8   a  is selected from an image data group  8 , and thereafter “Print” is selected in step S 203 , a screen (not shown) to select a printer for output is displayed on the menu screen  7 , and when the customer  2  designates a printer in step S 213 , the selected image data is printed out on the designated printer (step S 214 ).  
      (Uploading)  
      When an exposure image data  8   a  is selected from an image data group  8 , and thereafter “Upload” is selected in step S 203 , a screen (not shown) to select a server to be an upload destination is displayed on the menu screen  7 , and when the customer  2  designates a server to be the upload destination in step S 215 , the selected image data is uploaded to the designated server (step S 216 ).  
      (Slide Show)  
      When an image data group  8  or an individual exposure image data  8   a  from the image data group  8  is selected, and thereafter “Slide Show,” is selected in step S 203 , then musical piece selection screen  14   a,  as shown in  FIG. 11 , to select musical-and-vocal data to be played as BGM of a slide show is displayed on the menu screen  7 . This musical piece selection screen  14   a  displays, for example, switches (BGM  1  to  3  in the figure) that indicate musical-and-vocal data which the customer  2  has selected at the order shop in the retail store  3  or the like, or the customer  2  has provided, a switch that is used to download musical-and-vocal data through the Internet, and a switch that is used to select musical-and-vocal data which is stored in a PC by the customer  2 , while the customer  2  selects desired musical-and-vocal data from these in step S 217 .  
      When the customer  2  selects a piece of musical-and-vocal data and presses switch “Next”, the menu screen  7  displays slide effect setting screen  14   b,  as shown in  FIG. 12 , in step S 218 . This slide effect setting screen  14   b  displays, for example, an “Effect” column to set a method for display/erasure of image data, a “Display Size” column to set a display size of image data, a “Screen Switch” column to set a method of switching the screen, a “Background” column to set the background screen of a slide, and a “Frame” column to set a frame to be added to image data.  
      As “effects”, arbitrary known processes are included such as a fade-in/fade-out process that gradually displays/erases image data, a process to gradually enlarge/reduce image data, and a process to move image data up or down, and left or right on the screen, wherein a desired effect is selected from these effects. As for the means for setting an “effect”, setting an “effect” in a way more understandable to the customer  2  can be attained by performing a preview display for the effect of switching the slide of an image displayed in the slide displaying mode and thereafter setting an “effect” desired by the customer  2 . For example, the customer  2  may easily and practically confirm the effect of switching a slide by viewing a screen (for example, displaying in a size 400×300 instead of an actual screen size, for example, of 800×600) smaller than a screen for actual display in the slide displaying mode as a slide show; or the customer  2  may select a desired effect through actual display of a plurality of effects of switching a slide, as shown in  FIG. 23 . Further, as for “display size”, there are a mode for display on the entire screen and a mode for display with the size of image data as it is. Regarding “screen switching”, there are a mode for switching a screen with a customer&#39;s operation of a mouse, and a mode for automatic switching at a timing having been set with a musical-and-vocal data analysis means  6   i,  described later, from which an arbitrary mode is selected.  
      Further, it is also possible to set a background screen and provide decoration on the outer frame of image data, wherein the customer  2  selects a desired item from backgrounds and frames displayed on a pull-down menu. For example, when “Snow” is selected as a background, a screen with a snowy background screen of image data is displayed, and when “Ribbon” is selected as a frame, a screen is displayed, added with a ribbon on the outer frame of image data, by which effects of a slide show are enhanced. Incidentally, for slide effects herein, representative effects (for example, fade-in/fade-out for “Effect”, original image size for “Display Size”, automatic for “Screen Switching”, nothing for “Background” and “Frame”) are set as defaults, and the slide effect setting screen  14   b  may be displayed only in the case of changing an effect. These items are only examples, and any combination of the abovementioned items and combinations with other effects are allowed.  
      Next, when the customer  2  presses the switch “Next” after setting a slide effect, insertion screen  14   c  for insertion of an image and message, as shown in  FIG. 13 , is displayed on the menu screen  7  in step S 219 . This image/message insertion screen  14   c  displays, for example, an “Image Insertion” column to select an image to insert, a column to input a message to insert, an “Insertion Mode” column to select a mode to insert a message, and an “Insertion Position” column to select a position to insert the message.  
      This image/message insertion screen  14   c  is provided also to enhance the effects of a slide show, and, for example, in the case of selecting the theme song of a movie or an animation as musical-and-vocal data, the names of characterized symbols or the like corresponding to the musical-and-vocal data are displayed on the pull-down menu in the “Image for Insertion” column, which makes it possible to display a characterized symbol together with image data in a slide show by selecting an image from them, creating a feeling of unity between the played musical piece and the display screen.  
      Further, by inputting a message in a message input column and setting an insertion mode and an insertion position, the input message can be displayed in a telop together with display of image data and at a designated position on the screen, which increases the variety of customization, thereby enabling production of an electronic album responding to desires of a customer. Further, by describing additional information such as a message at the time of ordering an electronic album in step S 102 , this message can be displayed in the message input column, and, in case of giving the information-recording medium  5  of the present embodiment to an acquaintance or a friend, it is allowed to display, in a slide show, a message to the person who receives the gift, thus adding a commodity value to the information-recording medium  5 .  
      With regard to insertion of an image or a message, no insertion of image/message can be set as a default value, allowing display of the image/message insertion screen  14   c  only in the case when insertion of an image or a message is desired. It is not always necessary to set a slide effect or insert an image/message, which allows it to start a slide show just after a selection of musical-vocal data, in a case where a slide show is selected in step S 203 .  
      When selection of musical-and-vocal data, selection of a slide effect, and setting of image/message are terminated, the image data group  8  or selected individual-exposure image data  8   a  are displayed in step S 220  in the slide displaying mode, and the selected musical-and-vocal data is played together as BGM.  
      The electronic album reproduction program, of the present embodiment, not only displays image data and plays musical-and-vocal data, but comprises a slide show execution program to let the timing of displaying image data and the timing of playing musical-and-vocal have the following predetermined relationship, thereby increasing the effects of a slide show.  
      Specifically, the slide show execution program can cause a computer function as musical-and-vocal data analysis means  6   i  that computes the play duration of musical-and-vocal data, extracts the tempo, phrases, vocal data, and silent bars of musical-and-vocal data, and sets display timing of image data, and as image data analysis means  6   j  that extracts specific shapes and colors from the image data, and selects musical-and vocal data suitable for the image data, referring to the characteristics of the image data.  
      Thus, for example, the play duration of musical-and-vocal data is extracted from the format, the size, and the header information of the musical-and-vocal data, computes display duration per single image data by dividing the play duration by the number of image data to be displayed so that display of the image data terminates simultaneously with the termination of play of the musical-and-vocal data, or display of image data terminates simultaneously with the termination of play of a plurality of musical-and-vocal data.  
      Further, it is also possible to extract the tempo of a musical-and-vocal data according to the dynamics, the frequencies, etc. of a musical-and-vocal data, and to set the duration of slide effects (for example, the duration of fade-in/fade-out) to be matched with the tempo of the musical-and-vocal data, wherein a slide effect is set with a short duration for a musical piece with a fast tempo, and with a long duration for a musical piece with a slow tempo, thereby enabling matching between the tempo of a musical piece and a slide effect.  
      Still further, it is also possible to extract vocal data and silent bars of a musical-and-vocal data according to the dynamics, frequencies, and the like of the musical-and-vocal data and divide the musical piece into individual phrases, allowing, for example, to set a slide show so that each individual image data is displayed for each individual phrase, thereby synchronizing a phrase of the musical-and-vocal data and the display of the image data, which creates a feeling of unity between the musical piece and the images and increases the effects of a slide show.  
      Yet further, it is also possible to extract specific shapes and colors from image data by performing image processing on the image data, thus guess the scene of photography, and select musical-and-voice data, matching with the scene, from musical-and-vocal data recorded in advance, thereby allowing enjoyment of a slide show in which a suitable musical piece is played as BGM even if the customer  2  does not make selection of musical-and-vocal data.  
      As has been described, the slide show execution program of the present embodiment, not only displays image data and simultaneously plays musical-and-vocal data, but also sets display duration of image data and the duration of slide effects in synchronization with play duration, tempos, and phrases of musical pieces, and thus the effects of a slide show are greatly enhanced, compared with conventional slide shows. Further, in the information-recording medium  5  of the present embodiment, not only image data and musical-and-vocal data to be used for a slide show, but also an electronic album reproduction program are written in a computer readable state, and thus the customer  2  can easily view the electronic album and enjoy a slide show, just by inserting the information-recording medium  5  into a terminal such as a PC.  
      Further, with the information-recording medium  5  of the present embodiment, messages that the customer  2  described at the time of ordering an electronic album and characterized symbols that were registered corresponding to musical-and-vocal data, as necessary, are reproduced along with image data, which further increases the feeling of unity between the image data and the musical-and-vocal data, and the value in offering the information-recording medium  5  of the present embodiment as a gift is increased by being able to display a message addressed to a specific person.  
     Embodiment 2  
      Next, an information-recording medium, in which an electronic album according to a second embodiment of the invention is recorded, will be described, referring to FIGS.  14  to  16 .  FIG. 14  is a diagram showing a structure of an electronic album ordering system according to a second embodiment of the invention;  FIG. 15  is a flowchart showing an ordering procedure of the electronic album; and  FIGS. 16A and 16B  are diagrams showing display examples of an information-recording medium and a jacket produced by a system of the present embodiment.  
      In the first embodiment described above, only image data, musical-and-vocal data, and a computer program for reproducing and ordering them are written in the information-recording medium  5 , but the present embodiment is characterized in that, in order to increase the value of the information-recording medium  5  itself and indicate recorded image data and musical-and-vocal data, predetermined printing is performed on the surface of the information-recording medium  5  or the jacket of a storage case for containing the information-recording medium  5 .  
      In description of the present system, referring to  FIG. 14 , an electronic album order system  1  of the present embodiment comprises customer  2  who provides image data, an order shop, in retail store  3  or the like, which exhibits information-recording media  5  having recorded in advance musical-and-vocal data and having been subjected to printing, on the surface of the medium or the jacket of a storage case thereof that allows to identify musical-and-vocal data, and laboratory  4  that receives, from the retail store  3 , the image data and the information-recording medium  5 , and writes, computer readably, the image data and an electronic album reproduction program on the information-recording medium  5 . The retail store  3  is provided with counter  3   a  that receives the image data from the customer  2 , receives an order for an electronic album, and returns developed negative film  2   c  to the customer, and also exhibition rack  3   b  that exhibits the information-recording media  5  in which musical-and-audio data is recorded, while the laboratory  4  is provided with developing device  4   a  that develops undeveloped negative film  2   a  provided by the customer  2 , reading device  4   b  that reads the developed photographs and converts them into digital data, writing device  4   c  that writes data and computer programs to the information-recording medium  5 , and printing device  4   d  that performs printing to allow identifying each image data. The respective devices stated above may be arranged separately, and it is also allowed to make an integral arrangement of a pair of the developing device  4   a  and the reading device  4   b,  a pair of the reading device  4   b  and the writing device  4   c,  a set of the developing device  4   a,  the reading device  4   b,  and the writing device  4   c,  or a set of the developing device  4   a,  the reading device  4   b,  the writing device  4   c,  and the printing device  4   d.  Further, an arbitrary printer that makes common prints based on image data read by the reading device  4   b  may be provided, including an inkjet type, an electrophotographic type, a silver halide type, and others.  
      Referring to the flowchart in  FIG. 15 , described will be the procedure, on the electronic album ordering system  1  arranged as above, from the time the customer  2  provides image data to the time the customer  2  obtains information-recording medium  5  in which an electronic album is recorded. Although, in the following description, it is assumed that musical-and-vocal data is recorded in advance in the information-recording medium  5  exhibited in the retail store  3 , it is also allowed that only printing is performed with the information-recording medium  5  and recording of musical-and-vocal data is carried out in the laboratory  4 . The same as in the first embodiment stated above, the image data may be provided with a developed negative film or an information-recording medium instead of providing it with undeveloped negative film  2   a.    
      First, the same as in the first embodiment, in step S 301 , the customer  2  brings an undeveloped negative film  2   a  having been photographed with a film camera into an order shop in a retail store  3  or the like. In step S 302 , the customer  2  places an order of an electronic album having been brought in by the customer  2 , and writes, on order sheet  2   b  in a predetermined format, information that identifies the customer  2  as well as additional information such as a message to be displayed together with the image data. Further, the customer  2  may add a message to be printed on the information-recording medium  5  or on a jacket and/or information that identifies the customer to be provided with the information-recording medium  5 , and the like. Next, in the case of selecting image data in step S 303 , the customer  2  selects image data to be used for the electronic album, designating exposure numbers of a developed negative film or file names in the information-recording medium in step S 304 .  
      Next, in step S 305 , the customer  2  selects musical-and-vocal data to be played, as BGM of the electronic album, wherein, in the present embodiment, information-recording media  5  in which only musical-and-vocal data is written are exhibited on the exhibition rack  3   b  in the retail store  3 , and the customer  2  selects a desired information-recording medium  5  from among them. Incidentally, as shown in  FIGS. 16   a  and  16   b,  the information-recording medium  5  is preferably printed with music titles/artist names  22  on the surface thereof opposite the data writing surface or on the jacket of a storage case in the case of a CD-R for example, to indicate contained musical-and-vocal data therein. In this situation, in addition to the classification of the musical-and-vocal data (the names of musical pieces and artists), designs that increase commodity value may also be printed.  
      Then, in step S 306 , the retail store  3  sends the undeveloped negative film  2   a  the customer  2  has brought in, the information-recording medium  5  having been selected by the customer, and the order sheet  2   b,  to the laboratory  4 . In case the customer  2  has provided the image data in the form of digital data, the retail store  3  may write the image data onto the information-recording medium  5  that the customer  2  has selected.  
      Then, the laboratory  4  which has received the undeveloped negative film  2   a,  the information-recording medium  5  in which musical-and-vocal data is recorded, and the order sheet  2   b,  produces an electronic album provided with an electronic album reproduction program that contains a slide show execution program described in the first embodiment. In this occasion, when the image data is received as an undeveloped negative film  2   a  in step S 307 , the developing device  4   a  is used to develop the negative film, and the negative film is converted into digital data, using the reading device  4   b  such as a scanner or the like. When the image data is received as a developed negative film, the negative film is converted into digital data, using the reading device  4   b.    
      Then, in step S 308 , the image data read by the reading device  4   b  or the image data recorded in the information-recording medium, and the electronic album reproduction program are written onto the information-recording medium  5  selected by the customer  2  in a computer readable state to produce the electric album. If the customer  2  adds a message to be displayed together with the image data, the additional information is also written in the information-recording medium  5 .  
      Next, in step S 310 , as shown in  FIGS. 16   a  and  16   b,  the laboratory  4  prints, for example, an image row  23  of representative image data or image data selected by the customer  2 , on the surface of the information-recording medium  5  or on jacket  20  of a storage case so that the undeveloped negative film  2   a  is identifiable. In this situation, the name (not shown) of the ordering customer  2 , message  21 , date information  27 , memorandum column  26  in which the customer  2  himself/herself can write a note using a pen or the like, and other information, may be printed together.  
      Incidentally, the date information herein indicates the date, the time, and the season of photography, and includes the date of production of the image data, the date designated by the customer  2 , and the date of writing image data of the customer  2  and the computer program on the information-recording medium  5 . Further, in the case where a plurality of image data are recorded taking more than one day, the representative date (the most frequent photographing date), month, or the season may be indicated. By performing such printing on the surface of the information-recording medium  5  or on the jacket  20  of a storage case, the information-recording medium  5  can be customized, increasing the commodity value.  
      Further, for management, undeveloped negative film  2   a  or order sheet  2   b  received by the order shop in retail store  3  or the like is often given a unique number, possibly including symbols, such as a receipt number so that the film can be assuredly returned to the customer  2  later, wherein it is convenient for management to record the same number on the surface of information-recording medium  5  and on the jacket  20  of the storage case. If recorded in a form such as barcode  28  herein, the number can be easily read using a machine such as a barcode reader. Incidentally, a receipt number is adopted here, but the type of number is not limited to this, and any number convenient for production management in the laboratory  4  can be adopted.  
      Thereafter, in step S 311 , the information-recording media  5  in which the image data, the musical-and-vocal data, and the electronic album reproduction program are recorded, as well as the developed negative film  2 , are sent to the retail store  3 , and then provided by the retail store  3  to the customer  2  in step S 312 .  
      Then, the same as in the abovementioned first embodiment, the customer having received the information-recording medium  5  inserts the information-recording media  5  into a PC or the like, and executes the electronic album reproduction program and the slide show execution program to enjoy the electronic album and the slide show.  
      As described above, the information-recording media  5  in which the electronic album of the present embodiment is recorded is printed with music titles and artist names, and representative image data so that each vocal data and each image data are identifiable from all others, and further, the name of the customer, a message, etc. are printed as necessary, thereby allowing the customer to obtain an electronic album unique to the customer, which increases the commodity value to the information-recording media  5 .  
      In the above embodiment, although the customer  2  selects, in the retail store  3 , information-recording medium  5  having been subjected to printing that identifies each musical-and-vocal data, it is also possible to perform printing, all in the laboratory  4 , which makes the musical-and-vocal data and the image data identifiable. In this case, a list of musical-and-vocal data and designs for printing is provided in the retail store  3 , and the customer  2  designates desired pieces of music on the list. Further, although it has been described that the image data is written in the laboratory, in the case where the customer  2  provides the image data in an information-recording medium, it is possible that the retail store  3  writes the image data onto the information-recording medium  5 , and the laboratory  4  writes only the electronic album reproduction program. Still further, in the first embodiment, printing which makes each musical-and-vocal data and image data identifiable may be performed in the laboratory  4 .  
      In each embodiment described above, an electronic album produced by the laboratory  4  is sent to the retail store  3 , and the customer  2  receives the electronic album there. However, the electronic album in the present embodiment can be reproduced only with the information-recording media  5 , and since a message addressed to a specific customer is displayed or printed on the surface of the information-recording medium  5  or on the jacket of a storage case, the commodity value of the information-recording medium  5  itself is high, making it possible to use the information-recording medium  5  as a gift for an acquaintance or a friend. In this case, by giving the address, name, etc. of an acquaintance or a friend who receives the information-recording medium  5 , at the time of ordering, the information-recording medium  5  can be mailed directly from the laboratory  4  or the retail store  3 .  
     Embodiment 3  
      Next, described will be an information-recording medium in which an electronic album according to a third embodiment is recorded, referring to FIGS.  17  to  22 . FIGS.  17  to  22  are diagrams showing examples of screens displayed at the time of execution of an electronic album reproduction program according to the third embodiment.  
      In the aforesaid first embodiment, it was mainly described on functions and operations of the electronic album reproduction program and the slide show execution program. However, a screen which is displayed during execution of the electronic album reproduction program or the slide show execution program, particularly a display screen of image data group  8  and individual exposure image data  8   a,  is displayed in such a manner that customer  2  can easily select image data, more details of which will be described below.  
      Likewise, as shown in the first embodiment, when the customer  2  has inserted information-recording medium  5  in which a computer program of the invention is recorded into a computer terminal such as a PC, menu screen  7  as shown in  FIG. 5  is displayed. On this menu screen  7 , a plurality of image data groups  8  each of which is arranged by a set of individual exposure image data  8   a  are displayed, wherein display of each image data group  8  is possible.  
      Specifically, as shown in  FIGS. 17   a  and  17   b,  each image data group  8  is provided with an index image display region  25  for displaying individual exposure image data  8   a  in arrays, and tag  24  for identifying the image data group  8 , wherein, in the index image display region  25 , image data groups  8  corresponding to the respective tags  24  are displayed as if they were laminated sheets, and a sheet corresponding to a selected tag  24  is displayed as the front sheet. For example,  FIG. 17   a  shows the case where the upper tag  24  is selected from among the three tags  24 , and on the screen, individual exposure image data  8   a  corresponding to the upper tag  24  are displayed on the front sheet. When the middle tag  24  is selected, as shown in  FIG. 17   b,  individual exposure image data  8   a  corresponding to the middle tag  24  are displayed on the front sheet. In such a manner of display, the customer  2  can visually verify which image data group  8  the customer  2  is displaying.  
      This tag  24  indicates information to identify the image data groups  8  to allow easy selection of image data. Described with reference to  FIGS. 18   a  to  18   d  in which only the part of a tag  24  is enlarged, each tag  24  comprises a medium identifying section  24   a  that indicates classification of a photographic film or a medium (a memory card, an information-recording medium such as a CD-R, a digital camera, etc.) in which image data provided by the customer  2  is recorded, and an auxiliary identifying section  24   b  that indicates information to identify the image data recorded in the photographic film or the medium. For example, In  FIG. 8   a,  in order to identify an undeveloped negative film  2   a  provided by the customer  2 , the medium identifying section  24   a  indicates an illustrated image of the film, and further, in order to identify specific image data in the film, the auxiliary identifying section  24   b  indicates a date (Jul. 7, 2002) being the order date of the information-recording medium  5  of the invention, the photographing date, or the like, and a serial number (−001).  
      Likewise, in  FIG. 18   b,  an illustrated image of a memory card is shown, indicating that an information-recording medium such as a memory card was provided. In  FIG. 18   c,  an illustrated image of a CD is shown, indicating that an information-recording medium such as a CD-R was provided, while in  FIG. 18   d,  an illustrated image of a digital camera is shown, indicating that a digital camera or photographic images taken by a digital camera were provided. In such a manner, by indicating, on the medium identifying section  24   a,  an illustrated image of a provided photographic film or medium, the customer  2  can visually identify the type of a medium on which the photographic images of an image data group  8  are base on, which allows easy selection of an image data group  8 . Incidentally,  FIGS. 18   a  to  18   d  show only examples, and any other indication mode is allowed as long as the photographic film or medium provided by the customer  2  can be visually identified.  
      In  FIGS. 18   a  to  18   d,  the auxiliary section  24   b  shows a date such as the ordering date of the information-recording medium  5 , photographing date, or the like, and a sequential serial number. However, information that enables identifying of image data in a photographic film or a medium may be indicated instead of or along with a date. For example, as shown in  FIG. 19   a,  information (for example, the title of an entrance ceremony, school excursion, or wedding ceremony) showing the content of the image data may be described along with a date in the auxiliary identifying section  24   b,  and, as shown in  FIG. 19   b,  it is possible to indicate a typical exposure image data  8   a  included in the image data group  8  (for example, the individual exposure image data  8   a  at the start of a film, an individual exposure image data  9   a  selected by the customer  2 , the retail store  3 , or the laboratory  4 , etc.). With such an arrangement, the customer  2  can determine the content of image data included in an image data group  8  just by looking at a tag  24 , and thus the selectivity of image data is extremely improved.  
       FIGS. 19   a  and  19   b  shows only examples, and any content can be described in the auxiliary identifying section  24   b  as long as the content directly indicates information related to the image data or indirectly suggests it. A title or an individual exposure image data  8   a  to be indicated in the auxiliary section  24   b  can be designated at the time of ordering at an order shop.  
      Regarding the arrangement of tags  24  and the index image display region  25 , for example, as shown in  FIG. 20 , tags  24  may be provided above the index image display region  25 ; or as shown in  FIG. 21 , a plurality of sheets may be displayed with a smaller index image display region  25 ; or as shown in  FIG. 22 , tags  24  and the index image display region  25  may be displayed separately, having an image data group  8  corresponding to a selected tag  24  displayed in an index displaying mode. In addition to the abovementioned arrangements, in order to make a selected image data group  8  identifiable, the frame of a sheet and medium identifying sections  24   a  for displaying tags  24  may flash, the color of a sheet may change, or a sheet may be displayed in three dimensions to stand out.  
      As mentioned above, by displaying image data groups  8  and individual exposure image data  8   a  in a sheet comprised of index image display region  25  for displaying each exposure image data  8   a  in the index displaying mode, and tags  24  for indicating information on the type of a photographic film or a medium, and on the content of image data, even in the case of recording image data based on a plurality of photographic film or a plurality of media in the information-recording medium  5 , suitable image data can be visually selected, and thus, operationability in an electronic album display program and a slide show execution program can be greatly enhanced.  
      In all the above embodiments, in providing customer  2  with information-recording medium  5 , examples have been shown where musical-and-vocal information for emitting musical-and-vocal sounds in synchronization with display in a slide displaying mode is recorded in the information-recording medium  5  in advance. However, the invention is not limited to this, and it is also possible to provide the customer  2  with information-recording medium  5  in which information except this musical-and-vocal information is recorded, and the customer  2  can utilize musical-and-vocal information at the hand of the customer  2 , the musical-and-vocal information having been selected by the customer  2 . As a matter of course in this case, a computer program for correlation and/or synchronization between a slide show and the musical-and-vocal sounds may be recorded in the information-recording medium  5 . The customer  2  can enjoy a slide show similar to that in the abovementioned embodiment in which musical-and-vocal sounds are emitted based on musical-and-vocal information at the hand of the customer  2 .  
      As it has been described, an information-recording medium, in which an electronic album of the invention is recorded, and a slide show execution program have the following effects.  
      A first effect of the invention is that it is possible to view a slide show in which image data and musical-and-vocal data are synchronized with each other.  
      This is because the slide show execution program recorded in the information-recording medium can cause a computer to function as means for analyzing musical-and-vocal data and means for analyzing image data. For example, the play duration of musical-and-vocal data, and a tempo and phrases of a musical piece, are extracted. Based on this information, the display duration of image data and the duration of slide effect are automatically set; displaying of image data and playing of musical-and-vocal data are terminated simultaneously; and image data is displayed matching with the tempo. In such a manner, image data and musical-and-vocal data can be synchronized.  
      A second effect of the invention is that functions of the electronic album can be executed merely with the information-recording medium and without special software.  
      This is because in the information-recording medium of the invention, not only image data and musical-and-vocal data, but also an electronic album reproduction program, are recorded in a computer readable state, and thus, a customer only needs to insert the information-recording medium into a terminal of a PC or the like, after which the program starts and allows viewing the electronic album.  
      A third effect of the invention is that information-recording media can be identified, and thus the commodity value is increased.  
      This is because printing that enables identifying each musical-and-vocal data and each image data is performed on the surface of the information-recording medium of the invention or on the jacket of a storage case, and a design image, information specifying a customer, a message, etc. can be printed as desired.  
      A fourth effect of the invention is that even in the case where a plurality of photographic films or image data based on a plurality of media are recorded in the information-recording medium, it is easy to select an image data group and individual exposure image data.  
      This is because a sheet is displayed in displaying image data, wherein the sheet comprises an index image displaying region that displays pieces of exposure image data in the index display mode, and tags that indicate information on the type of a provided photographic film or medium and information on the content of image data. Thus, image data can be visually identified by a tag.  
      The information-recording medium of the invention can be used so that a customer who orders an electronic album, not only enjoys it, but can also use the information-recording medium as a gift. Further, the information-recording medium of the invention may be used so that the customer can give photographs of his/her child to his/her parents, distribute photographs taken at a wedding party to attendants, or distributes photographs of a trip to participants.
