Patent ID: 8654218

Claim:
An imaging object used for an image processing system which includes: an imaging unit which images a sheet of memo paper having positioning symbols and serving as the imaging object; an image acquisition unit which detects the positioning symbols from original image data imaged by the imaging unit, recognizes a predetermined area calculated based on the positioning symbols as a first range, extracts only image data existing in the first range to acquire this image data as extracted image data, and corrects the extracted image data based on the distance between the positioning symbols; and an image data storage unit which stores the extracted image data acquired by the image acquisition unit, detects a predetermined area based on the relative positional relationship between the positioning symbols, recognizes this range as a second range, and stores, as information related to image data read from the first range, predetermined information contained in an image handwritten in the second range, the imaging object comprising: a rectangular paper main portion; and the positioning symbols which are disposed in at least two locations out of areas near four corners of the paper main portion, and are created as symbol codes constituted by multi-valued graphics, wherein each of the positioning symbols has an emerging portion having a color value that is different from a ground color of the paper main portion and a non-emerging portion having the ground color of the paper main portion, the emerging portion includes a frame-shaped emerging portion having two straight line portions respectively parallel with two sides extending from a corner of the paper main portion and a corner portion where edges of the two straight line portions contact each other, and the non-emerging portion of the positioning symbol is an area having the ground color which is surrounded by the frame-shaped emerging portion, and the second range is located such that at least a portion of the second range is in contact with an outer perimeter of a virtual rectangle having opposing corners formed by one positioning symbol and an other positioning symbol disposed on the paper main portion, and has line segments disposed thereon to form a plurality of squares.
