Abstract

Abstract PURPOSE:To set an optimum representative point and a comparison area in response to number of picture elements of an image pickup element by providing a representative point memory control circuit and a representative point setting circuit setting the position of a representative point and using the representative point setting circuit so as to control a representative point memory circuit and an arithmetic memory circuit. CONSTITUTION:A representative point memory circuit 101 is controlled by a representative point memory control circuit 102 according to a setting data of a representative point setting circuit 103 to store a signal of the position of the representative point and to output the signal of the position of the representative point of a stored preceding field. Then an arithmetic circuit 104 obtains an absolute value signal of a difference signal between an input signal Vin and an output signal of the representative point memory circuit 101. Moreover, an arithmetic memory circuit 105 adds an output signal of the arithmetic circuit 104 at a comparison area in the same relation of position to each representative point by the control of an arithmetic memory control circuit 106. Then a minimum data required from an output signal of the arithmetic memory circuit 105 is obtained by a minimum arithmetic circuit 107.
