<p>PURPOSE:To miniaturize a circuit scale concerning a correlation value accumulating circuit to operate and accumulate the correlation value of an image signal, etc. CONSTITUTION:The correlation value of the representative point digitized by an arithmetic circuit 38 to enter and an image signal after 1 field more than this is operated, the correlation value is supplied and accumulated to an accumulating memory circuit 58, and after one accumulation of the correlation value, the minimum value of the accumulated correlation value is detected by a minimum value detecting circuit 66, the detected minimum value is subtracted from the correlation value supplied successively from the correlation arithmetic circuit 38 by a subtracter 50, and the accumulating quantity in the accumulating memory circuit 58 is decreased.</p> |
