Abstract:
An image processor comprising:(a) an image-signal-differential outputting unit which includes a group of receiving optics,for inputting an input image composed of an identifying-object image, which is made by taking an image of an identifying-object, and a background image, in which no identifying-object image is shown, by using the group of receiving optics, andfor outputting an image-signal-differential between a standard receiving optic which is specifically defined and a receiving optic designated one after another in the group of receiving optics, with respect to each of the receiving optic designated one after another;(b) a binary digit unit for inputting the image-signal-differential from the image-signal-differential outputting unit, converting the image-signal-differential to a value out of two values in binary digit indicating the identifying-object image and the background image, and outputting the value in the binary digit; and(c) an identification unit for recognizing the identifying-object taken as the identifying-object image in the input image, based on the value in the binary digit from the binary digit unit.
