The composite color television signal is divided into a plurality of picture element signals by sampling it, and the luminance and chrominance signals frequency-multiplexed in each of the plurality of picture element signals are separated. An arbitrary one of the plurality of picture element signals is extracted as a remark picture element. A plurality of picture element signals whose chrominance signal frequency multiplexed therein is of the same phase as that of the chrominance signal frequency multiplexed in said remark picture element signal is extracted as first reference picture element signals. A plurality of picture element signals whose chrominance signal frequency multiplexed therein is in opposite phase to that of the chrominance signal multiplexed in the remark picture element signal is extracted as second reference picture element signals. Plural kinds of computed picture element signals are formed by using the remark element signals and a part of the plurality of second picture element signals. A plurality of correlation state signals are formed by computing the remark picture element signal, a part of the plurality of first reference picture element signals and part of the plurality of second reference picture element signals. A part of the plurality of computed picture element signals is selected on the basis of the plurality of correlation state signals.
