PURPOSE: To realize a Hough transformed picture processing in a real time by judging the number of related curves at X and Y coordinate points in the digitized window of picture data, and searching the maximum cross point. CONSTITUTION: This device is provided with an image pickup device 10, A/D converter 14, picture processor 40, and neuron Hough processor 36. Then, is subjected to Digitized picture data, arid the maximum cross point of binary edge data in a polar coordinate space is detected. That is, a picture element having a value indicating the edge data from the picture array of plural frames is transformed into the polar coordinate space, and the plural maximum cross points of a related curve group are identified by a neuron Hough transforming processing. Thus, a Hough transformed picture processor in which the plural maximum cross points of the curve group related with the picture element transformed into the polar coordinate space by the hardware processing of the neuron Hough transformation can be identified, and a real time processing can be attained to the picture identification having a typical digital picture data preparing speed can be realized.
