摘要： PURPOSE:To detect a position of a moving part independently of the shape by applying left and right end detection of each line passing through an extracted contour, obtaining its intermediate point, obtaining the X coordinate of the moving part based on the coordinate of the midpoint and obtaining the Y coordinate of the moving part based on the position of an optional line or line group. CONSTITUTION:A left end detection circuit 8 and a right end detection circuit 10 detect the left end and the right end of the moving part of a video image as to each line. A center X coordinate detection circuit reads a coordinate x1 from a register 9 and a coordinate x2 from a register 11 synchronously with a horizontal synchronizing signal to obtain a center x-coordinate. Moreover, a y-coordinate detection circuit 8 counts number of horizontal synchronizing signal based on a vertical synchronizing signal and when the left end detection circuit 8 detects the moving area picture element, the y-coordinate of the picture element when an output of a comparator 6 is logical 1 from the count of the horizontal synchronizing signal. Then the coordinates X, Y obtained in average are used as coordinates representing the position of the moving part.
