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 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.

Claims

1. An input/display integrated information processing device, comprising:

image display means for displaying image information;

image input means for inputting two-dimensional image information from an item having a two-dimensional image when the item is placed upon said image input means, the two dimensional image having been present on the item prior to placing the item on said input means;

a visual coincidence structure for integrally combining a display screen of said image display means with an input screen of said image input means so as to establish visual coincidence of said screens as viewed by an user;

image extraction means for extracting a portion of the two-dimensional image information on said image input means;

image information storage means for storing two-dimensional image information extracted by said image extraction means; and

image information control means for controlling input/output operations of the two-dimensional image information;

wherein said image input means scans in the two-dimensional image information; and

wherein said image extraction means includes object image extraction means for extracting only image information in a portion corresponding to a surface of the item placed upon the image input means from the two-dimensional image information scanned by the image input means.

2. An input/display integrated information processing device according to claim 1, wherein said image extraction means includes required portion extraction means for, when the user previously draws a closed curve enclosing a required portion on the two-dimensional image, detecting said closed curve to extract only said required portion.

3. An input/display integrated information processing device comprising:

image display means for displaying image information;

image input means for inputting two-dimensional image information from an item having a two-dimensional image when the item is placed upon said image input means, the two dimensional image having been present on the item prior to placing the item on said input means;

a visual coincidence structure for integrally combining a display screen of said image display means with an input screen of said image input means so as to establish visual coincidence of said screens as viewed by an user;

image extraction means for extracting a portion of the two-dimensional image information on said image input means;

image information storage means for storing two-dimensional image information extracted by said image extraction means; and

image information control means for controlling input/output operations of the two-dimensional image information;

wherein said image input means scans in the two-dimensional image information; and

wherein said image extraction means includes required portion extraction means for, when the user previously draws a closed curve enclosing a required portion on the two-dimensional image on the item, detecting said closed curve to extract only image information in said required portion from the two-dimensional image information scanned by the image input means.

4. An input/display integrated information processing device according to claim 3, wherein said image extraction means includes enclosure addition means for, when the user previously draws a closed curve enclosing a required portion on the two-dimensional image, recognizing a shape of said closed curve, and for automatically adding a suitable enclosure to an extracted image to enhance appearance.

5. An input/display integrated information processing device comprising:

image display means for displaying image information;

image input means for inputting two-dimensional image information from an item having a two-dimensional image when the item is placed upon said image input means, the two dimensional image having been present on the item prior to placing the item on said input means;

a visual coincidence structure for integrally combining a display screen of said image display means with an input screen of said image input means so as to establish visual coincidence of said screens as viewed by an user;

image extraction means for extracting a portion of the two-dimensional image information on said image input means;

image information storage means for storing two-dimensional image information extracted by said image extraction means; and

image information control means for controlling input/output operations of the two-dimensional image information;

wherein said image input means scans in the two-dimensional image information; and

wherein said image extraction means includes enclosure addition means for, when the user previously draws a closed curve enclosing a required portion of the two-dimensional image on the item, recognizing a shape of said closed curve, and for automatically adding a suitable enclosure to an extracted image to enhance appearance, said enclosure addition means selecting said suitable enclosure based upon recognizing of said shape of said closed curve from a predetermined plurality of enclosures.
