FIG. 6 is a flowchart showing the intro flash mode, and FIGS. 7 and 8 are examples of corresponding display screens. FIG. 9 is a flowchart showing the interval flash mode. In FIGS. 6 and 9, steps having the same numbers as those in FIG. 1 have the same contents. If the intro flash mode is selected, the following processing is performed. First, M
The gate circuit 2 outputs the output data of the PEG image decoder 70
8. Supply to the video display processor (VDP2) 60 via the system control unit (SCU) 34. At this time, one image composed of the output data of the MPEG image decoder 70 is reduced to 1/9 the size of the screen of the television 20 and displayed on the upper left of the screen, that is, the raster (see FIG. 7A). ).

The mode of the multi-screen is the same as that of FIG.
There are two blocks. This intro flash mode automatically or manually reproduces the image and sound at the beginning of each track (song) one after another.
Every time a predetermined time elapses, in the case of manual operation, each time the 18 track skip button or the track reverse skip button is pressed, the currently displayed moving image is frozen, and the moving image of the next track is reproduced and displayed.

That is, in step S21 in FIG. 6, in order to capture (freeze) an image, it is determined whether a set time of, for example, about 5 seconds has elapsed (automatic increment), and a track skip button (forward) is set within this set time. (For direction) or track reverse skip button (for reverse direction)
It is determined whether or not is pressed (manual increment).
In other words, step S21 is YES when the track skip button or the track reverse skip button is pressed within the set time, or when these skip buttons are not pressed within the set time, when the set time has elapsed. Becomes Step S14A corresponds to step S1 in FIG.
In addition to 4, the display of the track number is performed. In step S22, the CD player 10 is controlled to jump to the next track.

In step S22, the track skip direction is changed depending on whether the track skip button or the track reverse skip button is pressed. FIG. 7 is a diagram showing the transition of the screen display in the intro flash mode from a to f in order of time. In the state a, the moving image (movie 1) of the first track (first song) is displayed at the upper left of the screen before 5 seconds have elapsed from the start of reproduction or before any of the skip buttons have been pressed. B indicates that 5 seconds have elapsed or the track skip button has been pressed once, and the moving image of the first song is frozen, and one still image (still 1) is displayed in the upper left block of the screen. This shows that the moving image of the second track is displayed in the next block. c and d show a state in which the track skip button is successively pressed and the still images (still 2 and still 3) are sequentially displayed in the upper left block of the screen from the left to the right. In the state of e, eight still images (still 1 to still 8) and one moving image (moving 9) are displayed. In this state, when the track skip button is further pressed to capture, the screen is displayed as shown in f. Circles, and the moving image (movie 10) of the latest track is displayed at the upper left of the screen.

FIG. 8 shows a display mode when the track skip button or the track reverse skip button of the control pad 18 is pressed during the display of the intro flash mode. 5 shows a case where the track reverse skip button is continuously pressed three times. By pressing the track skip button as shown in a, the display of the intro in the middle can be skipped, and by pressing the track reverse skip button as shown in b, the midway in the reverse direction can be skipped. A desired intro can be displayed by skipping the intro display.

Next, the interval flash mode shown in FIG. 9 will be described. If the interval flash mode is selected, the following processing is performed. First, the output data of the MPEG image decoder 70 is supplied only to the first work RAM 38 via the gate circuit 28 and the system control unit (SCU) 34, and is supplied to the video display processor (VDP2) 60 as in each mode described above. do not do. Therefore, the image constituted by the output data of the MPEG image decoder 70 is not displayed on the screen of the television 20. The mode of the multi-screen has nine blocks similar to FIG. In this interval flash mode, images are automatically and manually frozen at predetermined time intervals (automatic capture) or at an arbitrary timing (manual capture) to freeze and capture images one after another.
They are displayed sequentially. In the case of automatic, every predetermined time (interval) elapses, and in the case of manual, 18
Each time a predetermined capture button is pressed, the moving image is frozen and a still image is displayed sequentially from the upper left of the screen. In either case, the frames between the capture and the next capture are skipped and are not displayed.

That is, in step S21A of FIG. 9, in order to capture (freeze) an image, it is determined that a set time of, for example, about 5 seconds has elapsed (automatic increment), and the capture button is pressed within this set time. It is determined whether or not it has been performed (manual increment). In other words, step S21A becomes YES when the capture button is pressed within the set time or when the capture button is not pressed within the set time. In step S24, the image data is taken into the sprite buffer of the video display processor (VDP1) 58. In the next step S25, the display sets a sprite and switches the multi-screen display block to be displayed. With this series of operations, still images are sequentially displayed on each block of the multi-screen. TV 2
After all nine blocks up to the lower right of the screen 0 are displayed, the display returns to the upper left. The above-mentioned predetermined time (interval), which is the capturing interval in the automatic case, can be increased or decreased by the number of frames to be thinned out. That is, the display interval (interval) can be arbitrarily set in advance, for example, every two frames or every five frames.

Next, the zoom (enlargement / reduction) / scroll mode will be described with reference to FIGS. FIG. 10 is a block diagram functionally showing a part of the block diagram of FIG. The MPEG image decoder 70 has a decoder section 70A and an enlargement / reduction / scroll processing section 70B. By the function of the enlargement / reduction / scroll processing unit 70B, predetermined enlargement / reduction / scroll processing is performed by various commands from the control pad 18. FIG. 11 is a flowchart showing such processing.
FIG. 12 and FIG. 13 are diagrams showing a display mode of a screen in a zoom (enlargement, reduction) / scroll mode. The flowchart of FIG. 11 shows a procedure in which the second CPU 32 performs a process for zooming (enlargement, reduction) and scrolling according to a key input on the control pad 18. That is, the second CPU 32 sends the user's command to the enlargement / reduction / scroll processing unit 70B to process the image data.

In step S10 of FIG. 11, a command is read by a key operation input from the control pad 18. In step S32, it is determined whether or not a direction instruction key (up / down / left / right key) of the control pad 18 has been pressed. If YES, the coordinates indicating the display position are shifted according to the key pressed in step S33. The direction and distance of the shift are determined by the type of the pressed key, the pressed time, and the magnification at that time. here,
The coordinates are set in the first work RAM 38.
