Abstract
To provide an image processing device able to accurately discriminate a specified image in an input image data, the input image is converted to binary based on black and red color extraction blocks 6and 6in binary processing unit 1. These binary data are consolidated by an OR circuit and stored in storage device 2. Mark location detection unit 3 extracts a square mark from the image data stored in device 2. Pattern shape extraction unit 4 extracts another mark which is inside the square mark. Pattern matching unit 5 obtains and outputs the goodness of fit between the extracted marks and previously established marks.
