M42 may be accessed, and high-speed processing can be realized.

As described above, the patterns and characters on the screen are stored in the image memory 31 in an area different from the luminance data and the chroma data of the photographed video. This will be described in detail below.

As the image memory 31, as shown in FIG. 4, a 4 Mbyte video RAM is used. That is, this video RAM has 512 bits in the horizontal direction, 512 bits in the vertical direction, and 16 bits in the depth direction. Therefore, the capacity of the image memory 31 is 512 × 512 × 16 = 4, 194, 304 bits.

This corresponds to the number of effective pixels of one screen of the NTSC system. In this case, the number of samples in one screen is 640 × 480 = 307,200 pixels.

Assuming that the luminance signal is quantized by 8 bits, the capacity required for the luminance signal data is 640 × 480 × 8 = 2,457,600 bits as shown in FIG. 6A. Since a video RAM having a depth of 16 bits is used as the image memory 16, when this is allocated on a video RAM having a depth of 16 bits, the area required as the area Y of the luminance signal data is as shown in FIG. 6B. Then, an area of 320 in the horizontal direction and 480 in the vertical direction becomes 320 × 480 × 16 = 2,457,600 bits. In FIG. 3, an area consisting of (320 × 480) is assigned as an area Y of luminance signal data.

The character data area CG is an area of 32 bits in the horizontal direction, 256 bits in the vertical direction, and 16 bits in the depth direction.

That is, one screen for character display has 512 pixels in the horizontal direction and 480 pixels in the vertical direction as shown in FIG. 8A. In character display, four samples in the horizontal and vertical directions are treated as one sample, and are represented by two bits. In this case, the required capacity is (512/2) × (480/2) × 2 = 122,880 as shown in FIG. 8B.

In one embodiment of the present invention, as described above, when reproducing an image data file and an audio data file, a plurality of (for example, two) types of narration data files correspond to one image data file. (NRA0000.PMA), (NRB00000.PMA).
PMA). As an example,
One narration data file (NRA0000
0. PMA) is used for after recording after creating a plurality of image files. The other narration data file (NRB00000.PMA)
Is used to record environmental sounds and the like when the image file was created. The user can select the narration when reproducing the still image and the narration. FIG. 15 is a flowchart showing a process of selecting audio data at the time of reproduction in one embodiment of the present invention. FIG. 15 shows processing in the case of reproducing an electronic still album.

First, when the disc is loaded into the drive in step ST1, the file management data is reproduced, stored in the DRAM 42, and further stored in the RAM 26 of the CPU (step ST1).
2). The file management data includes U-TOC and directory information. It is checked from the file management data whether the mounted disc is of the Picture MD standard.

In step ST3, the directory (PIC) is read from the read file management data. MD) is checked. If the directory does not exist, the process ends. If there is a directory, a list of albums is displayed (step ST4). The album is
Up to 30 books can be stored in one disc. A cover image (index image) is set for each album. The cover image of the recorded album is divided and displayed on the screen of the liquid crystal display 3. For example, 15 cover images can be divided and displayed on the screen.

The user looks at the album list display and selects a desired album. In step ST5, it is determined whether an album selection input has been made. When an album is selected and input, a list of photos in the album is displayed (step ST6). Similarly to the album list display, for example, 15 pictures are divided and displayed on the screen. A photo is selected by a process such as clicking a photo switching button or clicking a desired photo (step ST7). The image of the selected photo is displayed on the screen. In this manner, operations such as execution of a menu and selection operation are performed using the GUI including the key input 29, the display 3, and the memory controller 28.

When the picture is displayed, the narration button is pressed, and a voice reproduction is instructed (step ST9).
For example, as shown in FIG. 17A, “narration playback” displayed on the screen displaying the selected photo
The cursor is moved to the narration button K1 by the cursor feed key, and clicking this button K1 (or another button for determination) instructs voice reproduction. The buttons K2 and K3 are used to switch the displayed photo.

When the narration button K1 is pressed, the presence or absence of a narration A file (corresponding to the narration data file (NRA0000.PMA)) is checked (step ST10). If there is a narration A file, it is checked whether there is a narration B file (corresponding to the narration data file (NRB0000.PMA)) (step ST1).
1).

If there are narration A and narration B files, a narration file selection display is performed in step ST12. In FIG. 17B, K4 is a narration file selection display. In the selection display K4, the user can select a narration by moving the cursor to the narration on the side to be selected and clicking this display (or another button for determination).

In step ST13, it is checked whether or not there is a narration A selection input. If narration A is selected, narration A is reproduced (step ST14). As shown in FIG. 17B, in the selection display K4, a bar is added to the display on the side of the selected narration, indicating that narration A has been selected.
Of course, the display indicating this selected item is inverted,
Blink etc. can be used.

If only the file of the narration A exists, the step ST is performed without selection display.
The process proceeds from step 11 to step ST14, and narration A
Is played. Also, when the narration B is selected and input (step ST16) while the selection display (step ST12) is performed, the narration B is reproduced.

The file of narration A is stored in step ST
If it is determined in step 10 that there is no narration B file, the presence or absence of a file of narration B is checked (step ST15).
If there is a file of narration B, narration B is reproduced (step ST17). If there are no files for narrations A and B, the process ends. In this case, "No narration" is displayed on the screen to notify the user that there is no voice data. Not only the display but also a buzzer or the like may be used.

As described above, in one embodiment of the present invention, it is possible to have a plurality of, for example, two pieces of audio data for one still image. When only one audio data file exists without playing back the audio data file, the audio data file is automatically reproduced, and the audio data is selected only when there are two audio data files. . Therefore, the operation for reproducing the audio data can be simplified.

[0121]

According to the present invention, each still image data can have a plurality of audio data. When reproducing the selected still image, only when there are a plurality of audio data, the audio data is selectively displayed. If there is only one audio data, the audio data is automatically reproduced. Further, when there is no voice data, a message to that effect is displayed. Therefore, even if the user does not know the presence or absence of the audio data accompanying the still image data to be reproduced, or the number of the audio data, effective audio reproduction can be performed by a simple operation.
