Patent ID: 8368781

Claim:
An imaging object used for an image processing system which includes: imaging unit which images an imaging object having positioning symbols; 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 a distance between the positioning symbols; and image data storage unit which stores the extracted image data acquired by the image acquisition unit, the imaging object comprising: a rectangular paper main portion; and the positioning symbols which are formed in at least two kinds of shapes and 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 of a first positioning symbol 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 first positioning symbol is an area having the ground color which is surrounded by the frame-shaped emerging portion, and the emerging portion of a second positioning symbol at least includes an 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 a rectangular emerging portion which is located inside the emerging portion having the two straight line portions and the corner portion, and the non-emerging portion of the second positioning symbol is an area between the emerging portion having the two straight line portions and the corner portion and the rectangular emerging portion.
