2. Description of the Related Art In a conventional electronic file system, when displaying a plurality of pages of document (image information) on a display, a method of displaying each page on the display is generally used. And when you want to see other pages, you can use the so-called page turning function to "previous page".
Or, an instruction such as "back page" is given to sequentially switch the display forward or backward one page at a time or continuously, for example, at intervals of 1 second.

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 or descending order. It was 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, in response to the demand to compare multiple pages in one document at the same time, the conventional function is to compare them at the same time if the page intervals that can be displayed by one page turning operation are not small. Can't
There is a problem.

As described above, it has 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. An image display device of an electronic file system, that is, an image display device connected to an electronic file system having such a function is conventionally known. However, when the user wants to compare multiple pages in one document at the same time when searching, the conventional function is:
The page interval that can be displayed with one page turning operation is
There is an inconvenience that the operability at the time of search is deteriorated because it is not possible to compare them at the same time unless they are small.

[0006]

SUMMARY OF THE INVENTION The present invention solves such inconveniences in the conventional image display device of the electronic file system, and is desirable when it is desired to simultaneously compare a plurality of pages in one document at the time of retrieval. Provides an image display device with improved operability during search by copying a page image to an empty area of the image display area and continuing to display the page even if a page turning instruction is given after that. The purpose is to do.
