Patent number: 6825849Abstract: In an information presentation apparatus, a documents parser reads out and analyzes desired document data from a documents storage unit to obtain attributes data of the document data, which is stored in a document attributes storage uni. A displaying attributes setting unit uses the document attribute information, or attributes data, stored in the document attributes storage unit to retrieve data from tables of document attributes and displaying attributes, and, based on the retrieval result, sets a displaying attribute for the relevant document data. A displaying data generator determines a displaying manner of the document data according to the displaying attribute thus set, and the document data is displayed on a displaying unit in the determined manner. Accordingly, a user can quickly estimate a document attribute suggested by the content of the document data, not by reading the document data, but only at a glance of the manner in which the document data is being displayed.Type: GrantFiled: September 5, 2000Date of Patent: November 30, 2004Assignee: Sharp Kabushiki KaishaInventors: Mitsuru Minakuchi, Azusa Umemoto
