Abstract
PURPOSE: To realize a high-speed processing and miniaturization through the hardware process for the device which tracks the centroid via the digital picture of the target subject.
CONSTITUTION: The signals given from coordinate signal generator circuit 3a and 3b pass through gate 5a and 5b controlled by the binary-coded picture signal 4 and then added at circuit 6a and 6b to be then supplied to circuit 10a and 10b. While signal 4 is supplied to circuit 8 after counted by counter 7. At circuit 8 the integer-foldvalue of the value of counter 7 are produced in sequence by the clock signals of circuit 9 and then compared at circuit 10a and 10b with each output value of circuit 6a and 6b in the bits of the same digit to each other in parallel. When the both become equal each other or either one side becomes larger than the other, the stop pulses are generated from circuit 10a and 10b to stop the operation of counter 11a and 11b counting the clocks of circuit 9. And the value at this moment shows each coordinate of the centroid.
