The procedure until the medium 5 is obtained will be described with reference to the flowchart of FIG.

First, in step S101, the customer 2
Brings the undeveloped negative film 2a photographed with a film camera to an order store 3 such as a convenience store. The image data is not limited to a photographic image captured by a camera, but may be image data obtained via a communication network such as the Internet or image data processed by the customer 2 using image processing software. May be. Further, in this embodiment, the image data reproduced by the slide show program is not limited to the one stored in the information recording medium 5, but may be the one stored in the hard disk of the computer terminal which reproduces the program. Need not provide undeveloped negative film 2a or image data.

Next, in step S102, the customer 2
Requests the information recording medium 5 to be created at the counter 3a,
Information or the like for identifying the customer 2 is entered on the order form 2b in a predetermined format. Here, when the customer 2 brings in the undeveloped negative film 2a, normally all of the photographs recorded on the undeveloped negative film 2a are written on the information recording medium 5, but the developed negative film and the information recording. When carrying the medium, only a part of the recorded photograph can be used. Therefore, when the customer 2 selects image data in step S103, the image data to be used in the slide show is selected in step S104 by designating the frame number of the developed negative film and the file name of the information recording medium. To do.

Next, in step S105, the customer 2
Determines whether to select music voice data to be played as BGM of the slide show. In this embodiment, the music voice data is stored in the storage means 4d of the laboratory 4, and when selecting the music voice data, the counter 3a of the order store 3 is provided with a list of music corresponding to the music voice data. In step S106, the customer 2 specifies a desired song from the list.

It is not always necessary to select the music voice data, and predetermined music voice data may be used. Further, the music voice data is not limited to that stored in the lab 4, and the customer 2 may bring and provide the music voice data of a predetermined format, such as the music voice data created by the customer 2 or It is also possible to use the music voice data acquired by the customer 2 from a music CD or the like, the music voice data acquired via a communication network such as the Internet, etc. as the BGM. Further, in this embodiment, the music sound data reproduced by the slide show program is the information recording medium 5.
The program is not limited to the one stored in the computer, but may be stored in the hard disk or the like of the computer terminal that reproduces the program.

Then, in step S107, the order store 3 sends the undeveloped negative film 2a brought in by the customer 2, the designation information of the music (when the music is selected) and the order slip 2b to the laboratory 4. In the lab 4, when the image data is received as the undeveloped negative film 2a (step S10)
In step 8109, the developing means 4a is used for development in step S109, and the negative film is converted into digital data using the reading means 4b such as a scanner.

After that, in step S111, the laboratory 4 sends the information recording medium 5 recording the image data, the music audio data, and the slide show program and the developed negative film 2c to the order store 3, and in step S112 the order store 3 is sent. To customer 2.

Next, the installation support method, which is a feature of this embodiment, will be described with reference to FIG.

Normally, an application such as an image display program or a slide show program is installed in a hard disk of a computer terminal and used. However, when a new function is added to the application and the version is upgraded, the installed application is also updated. Need to up. Even with the slide show program recorded on the information recording medium 5 of the present embodiment, when the information recording medium 5 is obtained for the first time, it is confirmed whether the same slide show program is installed in the computer terminal, and the installation is performed.
After that, when the information recording medium 5 is obtained again, it is necessary to confirm whether the version has changed and upgrade if the version is new.

However, it is troublesome for the customer 2 to check whether the program is installed in the hard disk of the computer terminal and how many versions of the installed program are. It is difficult for an unfamiliar customer to perform such installation and version upgrade work by himself.

Therefore, in this embodiment, the slide show program is acquired by the computer by a means for determining whether or not the same slide show program is already installed in the hard disk, and by referring to the version description file, the version of the installed slide show program is acquired. The slide show program of the optimum version can always be used by functioning as a means for comparing with the version of the program in the information recording medium 5 and a means for displaying the installation confirmation screen and the upgrade confirmation screen to execute the installation. .

The information recording medium 5 has a data structure as shown in FIG. 3, for example. Specifically, the automatic installer startup file (Autorun.inf), the image data storage folder (DCIM), the slide show application (Photoviewer), the application that executes the installation (SoundPicDiscIns.Exe), and the application version description file ( SoundPicDiscIns.In
i), a folder (BGM) for storing music sound data to be played as BGM of a slide show, and other executable files and applications. The image data storage folder stores image data for each lot (each photographic film). Folders are provided, and image data and thumbnail data for index display are recorded in each folder.

On the other hand, when the slide show program of this embodiment is installed in the computer terminal, a folder (SoundPicDisc) of the slide show program is created in "Program Files" in the hard disk,
An application (SoundPicDisc.Exe) for executing a slide show and an application version description file (SoundPicver.txt) are created therein.

If the application (SoundPicDisc.Exe) does not exist in the predetermined folder of "Program Files" in the hard disk of the computer terminal, it is determined that this slide show program is not installed, and the slide show program exists. Application version description file (Soun
dPicDiscIns.Ini and SoundPicver.txt) are compared to determine whether or not a version upgrade is necessary.

As described above, when the version description file is written in the information recording medium 5 and the slide show program is installed in the hard disk of the computer terminal, a folder with a predetermined name is created in a predetermined storage location, and the folder is stored in the folder. When the slide show program and the version description file are written in and the information recording medium 5 is set, a folder with a predetermined name in the hard disk is automatically searched, and if the slide show program exists, it is determined that the slide show program is installed and the application is installed. Since the version description files are compared, the installation confirmation screen and the upgrade confirmation screen are displayed, and the installation is executed, the optimum version of the slide show program can be installed by a simple operation.

The functions and operations of the slide show program of this embodiment will be described below with reference to FIGS. 4 to 7.

As shown in FIG. 4, the slide show program according to the present embodiment searches the computer for a folder or program in the hard disk to check whether the slide show program is installed or not. Version information comparison means 6b for checking the version difference by referring to the version description file in the medium 5 and the version description file in the hard disk, and installation execution means 6c for displaying the installation confirmation screen and the upgrade confirmation screen and executing the installation. An index display unit 6d for reducing image data and displaying an index, a slide show display unit 6e for simultaneously slidingly displaying image data and music audio data, and a slide show for setting slide show conditions. An image for selecting the music sound data that matches the image data by the condition setting means 6f, the music sound data analyzing means 6g that analyzes the music sound data and adjusts the display timing of the image data, and analyzes the image data to extract the characteristics. It can function as the data analysis means 6h.

The program of the present invention does not require the computer to function as all of these means, and at least functions as the installation state determination means 6a, the version information comparison means 6b, and the installation execution means 6c. It is also possible to add a known means other than the above to make it function.

The operation of the slide show program will be described with reference to the flowchart of FIG. 5 and the screen configuration examples of FIGS. 6 and 7. The slide show program can be a program dedicated to displaying the slide show, but the computer can also function as a means for processing and saving images, printing, e-mail, etc. in association with the display of the slide show. In the following description, it will be described as having the above functions.

First, in step S201, the customer 2
When the information recording medium 5 of the present embodiment is inserted into a computer terminal such as a personal computer, the slide show program is automatically activated, and the installation state determination means 6a investigates the folder in the hard disk of the computer terminal to show the slide show of the present invention. The existence of the program is investigated.

If it is not installed, the process proceeds to step S204. If it is already installed, at step S202, the version description file in the folder in which the slide show program is stored by using the version information comparing means 6b. (For example, "So
undPicver.txt ”) and the version description file written in the information recording medium 5 (for example,“ SoundPicDi.
scIns.Ini ”), if the versions are the same, a menu screen is displayed in step S206, and if the versions are different, a version upgrade confirmation screen is displayed to the customer 2 in step S203.

If the program is not installed in step S201 and the version is updated in step S203, in step S204,
The installation method, that is, whether to perform a full installation or a differential installation is determined, and in step S205, after displaying the installation confirmation screen, the installation execution means 6c (for example, "SoundPicDiscIns.
Exe ”) to newly record or overwrite the slide show program on the hard disk of the computer terminal. There is also a method of installing only the specified function as an installation method, and when such a custom installation can also be selected In step S204, the installation method selection screen may be displayed to allow the customer 2 to make a selection.

If the installation is completed, or the version is the same in step S202, or if the upgrade is not selected in step S203, the menu screen 7 as shown in FIG. 6 is displayed in step S206. . The menu screen 7 displays switches 9 to 14 for selecting processing to be performed on the image data.

After that, in step S207, when the customer 2 clicks the switches 9 to 14 corresponding to the desired processing with the mouse, the screens corresponding to the respective processings are displayed. For example, when “List” is selected, the image data in which the predetermined association information is recorded in the header area or the image data associated with the definition file is extracted, and the image data group in which the frame image data is displayed as an index is displayed. It is displayed for each photographic film, and when "image processing" is selected, brightness adjustment and color adjustment can be performed, and when "save" is selected, the selected image data is saved in the designated directory. Also, if you select "Email", the size of the image data to be attached to the email will be specified, the email input screen will be displayed, and the email with the selected image data will be sent to the specified address. If you select "Print order", you will be connected to the homepage of the lab that accepts print orders online, and high-quality printing of image data is possible.

If "slide show" is selected in step S207, a slide show setting screen 15 as shown in FIG. 7 is displayed. On the slide show setting screen 15, for example, an area in which the above-mentioned image data group 8 and each frame image data 8a are displayed, and a slide effect setting area 15 such as a slide interval and a slide switching effect.
a, a BGM setting area 15b for selecting music audio data to be reproduced together with the image data, and a selected image display area 15c in which the frame image data 8a to be slide-displayed are arranged in the display order.
And are displayed.

Then, after selecting the frame image data 8a desired to be slide-displayed from the image data group 8 and operating the BGM setting area 15b to select the music voice data to be played as BGM, the slide effect setting area 15a is selected. Operate to set slide effects such as slide interval and slide switching effect. For example, as the slide display interval, select the time to display each slide from the pull-down menu or directly input it, and use the pull-down menu as the slide switching effect to gradually display / delete image data. A desired effect is selected from fade-in / fade-out, an effect of gradually enlarging / reducing image data, an effect of moving image data from the top, bottom, left, and right of the screen. Then, according to the above setting, the selected frame image data 8a is slide-displayed simultaneously with the selected BGM.

At the time of the slide show, not only the image data is displayed and the music voice data is played, but in order to enhance the effect of the slide show, the display timing of the image data and the performance timing of the music voice data are predetermined. It is preferable to have a relationship. As a slide show program having such a function, the program described in the applicant's prior application (Japanese Patent Application No. 2002-13789) is suitable. The program described in this earlier application is outlined below.

The slide show program described in the prior application is
A music sound data analysis unit 6f which causes a computer to perform a process of calculating a playing time of music sound data, a process of extracting tempo, phrase, sound data, and rest marks of music sound data, a process of setting display timing of image data, and the like.
Or the process of extracting a specific shape or color from image data,
Image data analysis means 6 for performing processing such as selecting music sound data suitable for image data by referring to the characteristics of the image data.
It can be made to function as g.

Then, for example, the playing time of the music audio data is extracted from the format and size of the music audio data, header information, etc., and the playing time is divided by the number of image data to be displayed to obtain the display time per image data. The slide show can be set so that the image data is displayed at the same time as the music music data is played, and the image data is displayed at the same time as the music data is played.

Further, the tempo of the music voice data is extracted from the strength and frequency of the music voice data, the frequency, etc., and the slide effect time (for example, fade-in / fade-out time) is set according to the tempo of the music voice data, and the tempo is set. It is also possible to make the slide effect faster in the case of a music piece having a fast tempo and, conversely, lengthen the time of the slide effect in the case of a music piece having a slow tempo so as to match the tempo of the music piece with the slide effect.

Also, voice data of music voice data and rest marks are extracted from the strength and frequency of the music voice data to divide the music into phrases, and for example, one image data is displayed for each phrase. A slide show can be set, and by synchronizing the phrase of the music audio data and the display of the image data, a sense of unity between the music and the image is created, and the effect of the slide show can be enhanced.

Further, the image data is subjected to image processing to extract a specific shape and a specific color to estimate a scene of photography, and music audio data matching the scene is recorded in the music audio data previously recorded. By selecting and playing from the above, the customer 2 can also enjoy a slide show in which an appropriate music is played as BGM without selecting music audio data.

As described above, when the information recording medium 5 is inserted into the computer terminal by using the image display program (slide show program) of this embodiment,
The presence or absence of the program in the computer terminal and the version are automatically checked, and the installation confirmation screen and the upgrade confirmation screen are displayed. Therefore, the customer 2 only has to select whether to install or upgrade according to the instructions on the screen. You can install the optimal version of the program.

[0058]

As described above, according to the image display program of the present invention and the information recording medium having the program recorded therein, the program is installed or upgraded according to the instructions on the screen without performing a complicated operation. By simply selecting or, if the image display program is not installed in the computer terminal, new installation can be performed, and if the version is different, upgrade can be performed.

The reason is that a file describing the version information of the image display program installed in the information recording medium is written, and the image display program and the file describing the version information are stored in the computer terminal when the installation is executed. A folder is created, and the image display program is installed in advance in the computer by referring to an installation state determination means for automatically determining the presence or absence of the image display program in the hard disk and a file describing version information. The version information comparison means for comparing the version of the image display program on the information recording medium with the version of the image display program on the information recording medium, the installation confirmation screen, and the upgrade confirmation screen are displayed to execute the installation. This is because it is possible to function as a.

Therefore, the customer can always install the optimum image display program simply by inserting the information recording medium into a computer terminal such as a personal computer.
