At this time, when the display effect "diagonal slide" is executed, the flow of FIG. 28 is executed. First, the display effect time (0 to 960 frames) and the display mode (horizontal 1920 x vertical 1035, horizontal 1280 x vertical 1024,
According to (horizontal 1600 × vertical 1200), the setting range of the attribute memory unit set for each frame, the moving range of the display start position set for each frame, and the slanted slide range are calculated. For example, assuming that the slidable slide is performed from the upper left to the upper right, the display effect time is “3 frames”, the display mode is “horizontal 1920 × vertical 1035”, the slant slide start position is “horizontal −200 × vertical −300”, and the diagonal slide size is "Width 200 x length 300". The movement range of the attribute memory setting is calculated as ((horizontal 1920 + horizontal 200) / 3 frames) in the horizontal direction by calculation of “horizontal 707” and vertical ((vertical 1035 + vertical 300) / 3 frames).
It becomes "horizontal 445".

Next, writing is performed to the attribute memory means and the display start position setting means until the display effect time becomes 0 frame. The starting point of the partial slide of the first frame is "Horizontal 507
Then, the start point of the partial slide of the second frame is moved to “horizontal 1214 × vertical 590”.

As shown in the upper diagram of FIG. 27, in the first frame, the image obtained by rolling 1/3 of P02 is output.
The image memories 1 and 2 are selected and output 11 and P12. In P21, the image of P12 is output in the slidable slide range, and the image of P11 is output in the other ranges. In P22, the image of P11 in the diagonal slide range, and P1 in other
Two images are output. The coefficient register means (1
In step 40), 100% of P21 is output and displayed.

Similarly, in the lower part of FIG. 27, in the second frame, the image of P12 is displayed in the oblique slide range, and the image of P11 is displayed in the other range.

The display screen is as shown in FIG.

As a premise, as shown in the upper part of FIG. 13 and the current state of FIG.
Image data A, B, C, and D are stored in (115), respectively. As the current state, the display start position setting means (125) for the entire screen is in the state of the origin (0, 0), and the data of the image memories 1, 2, 3, 4 are stored in P01, P02, P03, P04. It is output as is. The plane selection means (130) selects the image memories 1 and 2, and P
The image A is output to 11 and the image B is output to P12. The attribute memory means (135) sets 0 for all pixels, and the image A is output to P21 and the image B is output to P22. 0 is set in the coefficient register means (140), 100% of the input of P21 is output to P3, and the image A is displayed as it is.

At this time, when the display effect "window movement" is executed, the flow of FIG. 30 is executed. First, the display effect time (0 to 960 frames) and display mode (horizontal 1
920 x length 1035, width 1280 x length 1024, width 16
00x length 1200), the moving range of the attribute memory means set for each frame is calculated, and the image in which the position of the image memory 2 is changed is set as the image in the window. For example, if the window is moved from left to right, the display effect time will be "3.
Frame ", display mode is" horizontal 1920 x vertical 103 "
5 ”, the window movement start position is“ vertical 500 ”, and the window movement size is“ horizontal 200 × vertical 300 ”. The moving range of the attribute memory setting is “horizontal 707” by calculating ((horizontal 1920 + horizontal 200) / 3 frames). Next, writing to the attribute memory means is performed until the display effect time becomes 0 frame. The start point of the window movement of the first frame is "horizontal 507 x vertical 5"
00 ”and the start point of the window movement of the second frame is“ horizontal 1
414x500 ".

As shown in the upper part of FIG. 29, in the first frame, the image B is output to the window at P21 and the image A is output to the windows other than the window. The image A is output to the window on P22, and the image B is output to the windows other than the window. This is displayed by outputting 100% of P21 by the coefficient register means (140).

Similarly in the lower part of FIG. 29, the image B is output to the window in the second frame, and the image A is displayed outside the window.
