Patent ID: 8705068

Claim:
An image processing system, comprising: an imaging object having positioning symbols which are disposed in predetermined locations that forms four corners of a square; an image acquisition unit which detects the positioning symbols from original image data imaged by the imaging unit, recognizing a predetermined area calculated based on the positioning symbols as a first range, and extracting only image data existing in the first range to acquire this image data as the extracted image data; and image data storage unit which stores the extracted image data acquired by the image acquisition unit wherein the positioning symbols are formed in at least two kinds of shapes and are created as symbols constituted by multi-valued graphics, each of the positioning symbols has an emerging portion having a color value that is different from a ground color of the imaging object and a non-emerging portion having the color close to the ground color of the imaging object, the emerging portion of a first positioning symbol includes two L-shaped emerging portions, and the non-emerging portion of the first positioning symbol is an area having the color close to the ground color of imaging object which is surrounded by the two L-shaped emerging portions, and the emerging portion of a second positioning symbol at least includes a L-shaped emerging portion, and a rectangular emerging portion which is located inside the L-shaped emerging portion, and the non-emerging portion of the second positioning symbol is an area between the L-shaped emerging portion and the rectangular emerging portion.
