Abstract
A FIG. 1 is taken by a camera having optical/electrical elements arrayed in matrix, signals of pixels of the picture taken by the camera 2 are converted into binary data in a binary circuit 11, and the binary data is temporarily stored in a binary data storage device 12. The reference point 0 is determined on the edge of the figure, and plural coaxial circle scanning lines A, B about the reference point 0 which differs from each other in radius are set. In arithmetic circuit 15, coordinate data of pixels on the circle scanning lines A, B is operated. In the detector 16, binary data of the pixels on the circle scanning lines A, B is detected. In the decision circuit 17, the vectors from the reference point 0 to the detected pixels on the circle scanning lines A, N, and the vector angle between the obtained vectors is operated. A speed signal according to the vector angle is generated for driving the first and second drive 7, 8.
