The image data processing unit 1 can also take in the image data stored in the image data storage unit 2, subject it to image processing, and store it again in the image data storage unit 2.

The image data storage unit 2 stores the image data processed by the image data processing unit 1. That is, the image data storage unit 2
In terms of its function, the locus storage unit 21 for storing the scroll locus image data image-processed by the locus image data processing unit 11 for a scroll locus and the scroll image data image-processed by the scroll image data processing unit 12 It has a scroll storage unit 22 for storing for scrolling, and a whole storage unit 23 for storing whole image data image-processed by the whole image data processing unit 13 for whole screen display. In addition, each storage unit 21-23
The image data is stored in parallel with.

The scroll instructing section 4 is for instructing retrieval of the image data displayed on the display section 3 by the scroll function.

The image coordinate analysis unit 5 includes a scroll instruction unit 4
The command is to analyze the image coordinates of the scrolled image and output coordinate data, which is a series of image coordinate analysis data indicating which part of the entire drawing information is scrolled by what kind of trajectory.

The multi-window processing unit 6 receives the image data stored in the image data storage unit 2, displays the scroll image data on a part of the display unit 3, and displays the scroll locus image data on the rest of the display unit 3 as a whole. The multi-window display, which is superimposed on the image data and displayed, is selectively performed. The multi-window processing unit 6 has, as its functions, an enlargement scroll display instruction unit 61 for enlarging and displaying a part of the drawing information, and a whole window or drawing information by using a multi-window on a specific area of the display unit 3. A whole / trajectory display instruction unit 62 for overlappingly displaying a scroll locus indicating how a part of the above is scrolled. Instead of the multi-window processing unit 6,
The image data processing unit 1 may previously perform image processing for displaying the entire drawing information in a specific area of the screen by a multi-window based on the image data.

Next, the operation of the display processing device configured as described above will be described.

Now, it is assumed that desired image data is stored in the overall storage section 23 of the image data storage unit 2. The image data processing unit 1 reads out this desired image data from the image data storage unit 2, and the scroll image data processing unit 12 scrolls a part of the drawing information to be enlarged (doubled here) for display. Image processing for generating image data is performed. At the same time, the whole image data processing unit 13 performs image processing as whole image data for displaying the whole drawing information. The image-processed scroll image data is stored in the scroll storage unit 22, and the whole image data is stored in the whole storage unit 23.

The multi-window processing unit 6 receives the scroll image data and the whole image data, and the enlarged scroll display instructing unit 61 doubles the entire display screen based on the scroll image data as shown in FIG. The enlarged image is displayed as an image for scroll display.

On the other hand, the whole / trajectory display instructing section 62 displays an image of the entire drawing information in a multi-window display in the trajectory display area A1 set at the upper left of the screen of the display section 3 based on the whole image data. Further, of the entire drawing information displayed in the trajectory display area A1, the image portion currently displayed is surrounded by a rectangular frame and displayed as an area A11.

In this state, when a scroll instruction is given in the scroll instruction section 4 with a mouse or a scroll key (not shown) in order to search for image data, the image coordinates of the scroll instruction are converted into the image coordinate analysis section 5. Is analyzed and the coordinate data is output. Thus, when the scroll of the scroll image data is executed, the scroll locus is obtained, and the locus is displayed in the locus display area A1 as shown in FIG. That is, the route scrolled from the area A11 to the area A22 is indicated by the solid line L1.

Next, in the display state as shown in FIG. 3, after further scrolling, scrolling to the area A12, the state in which the enlargement magnification is changed from 2 times to 4 times and scrolled is shown in FIG. Show.

In this process, the scroll image data is subjected to image processing for magnifying four times and stored in the scroll storage unit 22, and the scroll trajectory image data for scroll trajectory display is generated and subjected to the image processing.
