2. Description of the Related Art In the conventional electronic filing system,
When displaying a document (image information) of a plurality of pages on a display, a method of displaying each page on the display is generally used. Then, when the user wants to see another page, a so-called page turning function is used to give an instruction such as "previous page" or "back page" to forward / backward one page at a time or continuously, for example, at 1 second intervals.
The display was switched in the backward direction. However, such a conventional page turning method has many inconveniences such as difficulty in grasping the context of pages in a document, complicated operation, and difficulty in determining ascending order or descending order. As one method for solving such inconvenience, it is necessary to set a plurality of overlapping display areas for displaying a plurality of documents (image information) and change the position of the image display area for displaying the image information. A display method of sequentially displaying has been proposed (JP-A-2-183869).

According to this display method, it becomes easier for the user to search for image information that the user wants to see, as compared with the conventional page turning function. However, even if the page you want to see slowly is displayed during the page turning operation, unless the page is the last page of the pages that can be displayed at one time, when the next page is displayed in due time, the page below the page is displayed. There is a problem in that it is hidden by (the prior art corresponding to the invention of claim 1).

Secondly, since it is a method of displaying a plurality of pages on one screen, the display area for one page is small, and compared with a normal display method for displaying only one image information for one page. However, there is an inconvenience that the image is difficult to see (the prior art corresponding to the invention of claim 2). Third,
When a plurality of pages are displayed, one page is an image to be viewed in a reduced size and another page is an image to be viewed in an enlarged size, such a request cannot be satisfied ( (Prior art corresponding to the invention of claim 3).

Fourth, the display magnification of all pages can be changed by the above display method as well, but when the portion to be viewed is hidden under another page, that portion is displayed. Since it is not performed, it cannot be dealt with only by changing the magnification (conventional technology corresponding to the invention of claim 4). As described above, an electronic filing system having a function of setting a plurality of overlapping display areas for displaying image information on the display means and sequentially displaying the image information when the position of the image display area for displaying the image information is changed 2. Description of the Related Art Image display devices, that is, image display devices connected to an electronic filing system having such a function are conventionally known. However, when the page that the user wants to see at the time of search is hidden under another page, or when the display magnification is small, it is not possible to deal with it sufficiently, and the operability at the time of search is reduced. there were.

In the next step # 24, the image data is expanded. This processing is performed in order to restore the original image data because the image data stored on the optical disk 10a in FIG. 1 is compressed by a compression method such as HM, MR, MMR. In step # 25, the scaling processing of the image data is performed.

Proceeding to step # 26, the parameter of the upper left coordinate (Xs, Ys) is acquired from the matrix 2 shown in FIG. In the next step # 27, the image data storage address ADDR is set in the matrix 2. At step # 28, the image data is copied to the VRAM 8 of FIG.

By the processing of these steps # 26 to # 28, the partial image data of the page displayed on the display is stored in the memory 2, and its address is set in the storage address ADDR of the matrix 2 to perform the display operation. Will be possible. Next, in step # 29, it is checked whether the number of display pages reaches the number MAX of image display areas.

If the number of display pages does not reach the number MAX of image display areas, D = D in step # 30.
Set to +1. In step # 31, timer processing is performed.
This processing is performed in order to display each page at a constant time such as an interval of 1 second. The timer 7 of FIG. 1 performs this process.

Then, the process returns to the previous step # 22,
The same processing is performed thereafter. In addition, as a result of the determination in step # 29, the display page is the number MAX of image display areas.
