<p>PURPOSE:To constitute the system so that a page in which desired contents are mentioned can be efficiently found out by extracting a designated area in a page of a document from each page and displaying it on the same screen. CONSTITUTION:When an extraction display area of each page of a document is designated by an extraction display area designating means B, a coordinate/ bit map width converting means C converts its coordinate to bit map width, and a display start position calculating means D calculates a display start position of each document data by each bit map width. In accordance with these bit map width and the display start position, a display data generating means E generates display data by document data extracted from each page of a document stored in a document file memory A, and displays it on one screen of a display means F. Accordingly, the contents of plural pages of the document can be looked at simultaneously without reducing them. In such a way, a page in which desired contents are mentioned can be retrieved efficiently.</p> |
