Abstract

PURPOSE:To execute an object graphic form recognition processing by a single hardware constitution, and to shorten the processing time, by generating a read-out address of a memory in the direction to the center axis from a graphic form frame containing a recognition object graphic form, and in the direction to the graphic form frame from the center axis. CONSTITUTION:A recognition object graphic form which is symmetrical to the X axis and the Y axis is stored on a picture memory 8, a video information of the graphic form is read from the memory 8, is inputted to an XY projection extracting part 1, and the information is projected onto the X axis and the Y axis of the extracting part 1. By this projection, coordinates of the center point are derived from a graphic form frame of coordinates where an object symbol exists. Based on said coordinates, the number of picture elements along the X axis and the Y axis in the graphic form frame is counted by address generation counter parts 2, 3, and its count value is inputted to address generation parts 4-7. Subsequently, addresses along the X axis and the Y axis are generated in the direction to the center axis from the graphic form frame, and in the direction to the graphic form frame from the center axis, respectively, contents of the memory 8 are read out by said addresses, and the graphic form is recognized by a feature extracting part 9.
