- step S107 the image data (including still image data, moving image data, and data including image information) recorded in the digital camera 7, media 8, and server 11 is written to the recording medium 9 in step S107. Select the image data to perform.
- the permitted capacity setting means 17 reads the data size of the selected image data, such as header information, and determines the data size of the permitted capacity power image data (recording schedule). Calculate the capacity (recordable capacity) minus (capacity). The relationship between the permitted capacity, the scheduled recording capacity, and the recordable capacity is shown schematically in Fig. 9 (b). When the permitted capacity is X and the scheduled recording capacity is Y, the recordable capacity is X — Y.
- the display control means 18 can cause the display means 5 to display an image selection screen 20 as shown in FIG. 13 (b).
- the image selection screen 20 displays, for example, a list of images based on the image data.
- the recordable capacity is displayed by subtracting the capacity of the selected image data from the permitted capacity.
- step S109 If the recordable capacity remains in step S109, the process returns to step S107 to select the next image data, and this step is repeated to select image data that fits within the permitted capacity. When the recordable capacity is exhausted, the selection of the image data is finished, and the image data selected in step S110 is read from the medium 8 or the like.

- the moving image data may be generated by adding the difference data based on the slide effect set by the slide show program to the still image data.
- step S113 the data for the image reproducing device, the associated file and the like (hereinafter collectively referred to as an image reproducing device data group) generated as necessary are recorded on the recording medium.
- step SI 14 the original image data, reduced image data, information files, music data, etc. (hereinafter collectively referred to as a computer device data group) are stored in the recording medium 9 in step SI 14. Write and finish the process.
- step S107 When writing data, if only the image data (original image data) selected in step S107 is written to the recording medium 9, the image data will not be written exceeding the permitted capacity. However, when other data is written in addition to the original image data, there is a risk that these data will be written exceeding the permitted capacity. In such a case, for example, as shown in FIG. 10, a spare area is provided at an arbitrary position (preferably the innermost circumference) of the recording medium 9, and the original image data is written in the area of the permitted capacity. However, if other data such as reduced image data, image reproduction device data, and applications are written in the spare area, the above-described problems can be avoided.

- the information specifically the information in the program memory area and the guidance given at the time of CD-R molding.
- the specific configuration of the identification information is arbitrary, and guide grooves other than those described above Modulation (ATIP) lead-in start time, maximum lead-out start time, etc. can also be set as appropriate so that they can be used as identification information, making it easy and reliable whether or not the recording medium is properly created. Can be identified.
- step S204 the control program causes the recording device 1 to function as the permitted quantity setting means 21, and the permitted quantity setting means 21 permits writing based on the read identification information. Specify the quantity of image data to be used.
- this permitted quantity can also be set arbitrarily.
- the power image data can be set to 60 frames, Z120 frames, Z24, 0 frames, etc.
- image data When image data is included, it must be set so that it does not exceed the free space of recording medium 9.
- information associated with this permitted quantity is added to an arbitrary position of the identification information so that the permitted quantity can be specified from the identification information. For example, if the identification information is YYMDyyyXXXXXXAAB, the last B is divided into xZyZz corresponding to 60 frames, Z120 frames, and Z240 frames. And write it on the recording medium 9.
- step S205 the control program causes the recording apparatus 1 to function as the display control means 18, and the display control means 18 displays on the display means 5 in step S204, for example, as shown in FIG.
- the display screen 19 is displayed, and the set permitted quantity is displayed.
- step S206 the medium 8 is loaded into the media loading unit 2 of the recording apparatus 1, or the digital camera 7 or the mobile phone 7a with a camera is connected to the device connection unit 3, or the network connection unit is connected to the communication network.
- step S207 image data to be written to the recording medium 9 is selected from the image data recorded on the digital camera 7 and the medium 8 and the image data recorded on the server 11.
- the permitted quantity setting means 21 calculates the quantity (recordable quantity) obtained by subtracting the quantity of the selected quantity of image data.
- the display control means 18 causes the display means 5 to display an image selection screen 20 as shown in FIG.
- the recordable quantity calculated according to the quantity of the selected image data can also be displayed.
- step S209 If the recordable quantity remains in step S209, the process returns to step S207 to select the next image data! ⁇ ⁇ ⁇ ⁇ Repeat this step to select the image data for the permitted quantity.
- the image data selected in step S210 is read.
- the image data instead of the user selecting image data one by one, the image data may be automatically selected in a predetermined order (for example, descending order of file names)! Therefore, the selected image data may be read each time image data is selected.
- control program causes the recording device 1 to function as the data generation unit 13, and the data generation unit 13 reduces the data size of the read image data in step S211 as necessary. Reduced image data such as data and screen nail image data is created.
- step S213 the image reproducing device data and the image reproducing device data group such as the association file generated as necessary are written in the recording medium 9, and in step S214, the original image data and the necessary data are recorded.
- the computer device data group such as reduced image data, information file, and music data is written in the recording medium 9 and the process is terminated. At that time, when writing other data in addition to the original image data, the total number of data may exceed the permitted quantity. If the authorized quantity is the quantity of the original image data, there is no problem! /.
- the identification information for specifying the type of the recording medium 9 that is associated with the quantity of writable image data outside the logical address area The control program recorded on the recording device 1 or the recording medium 9 reads the identification information from outside the logical address area of the recording medium 9, and writes the identification information based on the identification information.
- the quantity of image data permitted to be included is specified, and the quantity is displayed on the display means.
- the user can select and purchase a recording medium 9 having a price corresponding to the quantity of image data to be written, so even if the quantity of image data to be written is small, the image data can be written at an appropriate price.
- the use of a service for writing image data to the recording medium 9 can be promoted.
- the reason is that identification information for identifying the type of the recording medium associated with the writable capacity and quantity is recorded outside the logical address area of the recording medium. External force of the logical address area of the recording medium This identification information is read, and with reference to the read identification information, the capacity of the recording medium that is less than the actual free capacity or the image data that is permitted to be written The user selects the type of recording medium that matches the capacity or quantity of the image data to be written, in order to perform control to display the permitted capacity or the quantity of permitted image data on the display means. Thus, the image data can be written on the recording medium.
