PURPOSE:To display plural images of different degrees of display magnification on a single screen. CONSTITUTION:The document information including plural degrees of display magnification and a 1st address are stored in a document information store part 1. The frame information including the frame types and in index are stored in a frame (medium area) information store part 2. Then the address information including a 2nd address, the frame image data offset, and a frame image data area address are stored in an address information store part 3 respectively. When the document information and the display magnification are designated through a keyboard 7, a display part 3 reads the corresponding frame image data out of an image data store part 4 based on the corresponding address information designated by the corresponding document information. Then the image related to the corresponding frame is displayed in the designated display magnification. Therefore plural images of different degrees of display magnification are displayed on a single screen when plural degrees of display magnification are designated by an operator. |
