ABSTRACT:
An input/display integrated information processing device has: image display circuit for displaying document and image information; image input circuit through which information of an image such as a picture, a photograph, documents drawn or written on a sheet presented by the user can be an input; a visual coincidence structure for integrally combining a display screen of the image display circuit with an input screen of the image input circuit so as to establish visual coincidence of screens as viewed from the user; contact information detection circuit for, when a finger of the user, the sheet presented by the user, or the like makes contact with the contact information detection circuit, detecting information of a contact position, the contact information detection circuit being disposed on the whole of the input screen of the image input circuit or the display screen of the image display circuit; image extraction circuit for automatically extracting only a required portion from image information input through the image input circuit; image information storage circuit for storing the image information; image synthesize circuit for combining the image with an image which is already displayed and stored; and image information control circuit for controlling input/output operations of the image information.
