FIGS. 3 and 4 are flowcharts for explaining the display operation according to the embodiment of the present invention, and FIG. 5 is a diagram for explaining the operation. Next, the operation of the embodiment of the present invention will be described with reference to FIGS.

In forming a window, step S1
In FIG. 1 (abbreviated as S1 in the figure), the working R is performed by, for example, reading data from the floppy disk 15 or inputting data from the keyboard 11.
Data is created on the AM 5 and stored as image data 71 in a previously partitioned area of the image memory 7. Subsequently, in step S2, a window W1 forming process is performed, and a window frame 711 is set.

Subsequently, in step S3, the ratio between the size of the image data 71 and the size of the window frame 711 is calculated. For example, as shown in FIG.
When the window frame 711 is positioned with respect to the display data 71, the ratio of the left-side remaining portion, the display portion, and the right-side remaining portion is a ratio of 11:12:13. Subsequently, step S4
In, the scroll bar patterns 72 and 73 as shown in FIG. 1 are formed in the image memory 7 by l1, l2 and l3. FIG. 5 about the scroll bar pattern 73
To explain with reference to (B), a blank portion 731 is formed at the center portion, and l1 + l3 are combined on both sides to form a hatching pattern portion 732.

The vertical scroll bar pattern 72 is formed in a similar manner. Scroll bar patterns 72 and 7
No. 3 is allocated so that the hatching pattern is not displayed at the corresponding ends of the windows W2 and W3 when the window frame 711 moves to the end of the image data 71.

Thereafter, in step S5, each image data is transferred to the video RAM 8, and only the data in the window is displayed. In step S6, the mouse 13
When a scroll operation is instructed by a key operation such as a key operation, a memory address is set in step S7, and corresponding image data is transferred to the video RAM 8.

Next, the above-described transfer operation and scroll operation will be described in detail.

In step S11, for example, N bytes of image data corresponding to the window W1 are sequentially read from the address pointer AP1 of the image memory 7, and the video R is read.
The data is transferred to the AM 8 and written starting from the start point VAP1. Subsequently, in step S12, for example, M-byte image data corresponding to the window W2 is sequentially read from the address pointer AP2 of the image memory 7, transferred to the video RAM 8, and written starting from the start point VAP2. Subsequently, in step S13, for example, P-byte image data corresponding to the window W3 is sequentially read from the address pointer AP3 of the image memory 7, transferred to the video RAM 8, and written starting from the start point VAP3. By the above processing, the CRT display 1
A window as shown in FIG.

By operating the mouse 13, the arrow pattern 90 is pointed, and the mouse 13 is moved to shift to scroll processing, and scrolling operations in the up, down, left, and right directions are performed. That is, when the start of the scroll interruption process is instructed in step S14, step S15
In, it is determined whether or not vertical scrolling is performed. If scrolling in the left-right direction, subsequently, in step S16, it is determined whether or not scrolling is in the left direction. If scrolling is performed in the vertical direction, step S21 is performed.
In, it is determined whether or not scrolling is upward.

If scrolling to the left, step S
In step S17, AP1-1 is set as the new AP1, and in step S18, AP3 + 1 is set as the new AP1.
3 is assumed. If scrolling to the right, step S1
At 9, AP1 + 1 is set as a new AP1, and subsequently,
In step S20, AP3-1 is set as a new AP3. If scrolling upward, in step S22, AP1-n (n is the number of horizontal data of the image data 71) is set as a new AP1, and in step S23, AP2 + m (m is the number of horizontal data of the image data 72). Is a new AP2. If scrolling downward, in step S24, AP1 + n is replaced with the new AP.
Then, in step S25, AP2-m is set as a new AP2.

As described above, the address pointer is updated, and after waiting for a predetermined time, the above-described steps S11 and S11 are performed.
By executing steps 12 and S13, windows W1, W2 and W3 are scrolled. That is,
If scrolling to the left, the data in window W1 is shifted to the right and new data is displayed at the leftmost end. Further, the scroll bar pattern in the window W3 is shifted in the direction opposite to that of the window W1, the hatched pattern portion indicating the remaining portion at the right end increases, and the hatched pattern portion at the left end decreases. If scrolling to the right,
The data in the window W1 is shifted to the left, and new data is displayed at the rightmost end. Further, the scroll bar pattern in the window W3 is shifted in the direction opposite to that of the window W1, so that the hatched pattern portion at the right end decreases and the hatched pattern portion at the left end increases.

In the case of scrolling upward, the data in the window W1 is shifted downward, and new data is displayed at the uppermost end. Also, the scroll bar pattern in the window W2 is shifted in the opposite direction to the window W1,
The hatching pattern at the lower end increases and the hatching pattern at the upper end decreases.

When scrolling downward, the data in the window W1 is shifted upward and new data is displayed at the lowermost position. Also, the scroll bar pattern in the window W2 is shifted in the opposite direction to the window W1,
The hatching pattern at the upper end increases and the hatching pattern at the lower end decreases.

If it is assumed that the data ratio of the windows W1, W2 and W3 is 1: 1: 1, the above-mentioned method may be used. However, since the image data 71 and the image data 72, 73 have different ratios in general, Preferably, each time the scroll processing of the window W1 is performed a plurality of times, the windows W2 and W3 are scrolled once. The scroll ratio may be determined by the ratio between the image data size and the window frame size.

[0031]

As described above, according to the display method of the present invention, the ratio between the display size of the data resource and the size of the display data in the window is calculated, and the scroll bar pattern based on the calculated ratio is generated. The scroll bar pattern is moved in the direction opposite to the moving direction in synchronization with the scroll instruction of the display data in the window. In particular, since the scroll bar pattern is moved and displayed only by changing the read position of the once generated scroll bar pattern, the load on the CPU is small and drawing can be performed in real time.
