PURPOSE:To discriminate a pattern in desired sequence with a simple constitution without using the complicated timing circuit by storing a camera and the selecting sequence of control information to a memory group and reading a contents by the prescribed signal such as a discriminating starting signal. CONSTITUTION:Plural object patterns 1a-1n are photographed by TV cameras 2a-2n, the image pick-up signal of the cameras 2a-2n is changed over successively by a camera selecting circuit 3 under the control of a control circuit 5, and made binary by a binary circuit 2. The circumference of the pattern of the image pick-up screen is detected by a position correcting circuit 8, the correcting quantity from the prescribed reference point is obtained, and by the correcting quantity, the window area is formed at a window generating circuit 9. To a control information memory 14, the control information of the cameras 2a-2n and a memory control circuit 13 is set by a panel setting part 4. By the discrimination starting signal from the control part 5, the contents are read, circuits 6, 8 and 9 are controlled, and the pattern can be easily discriminated at a discriminating circuit 12 without using the timing circuit. |
