Abstract

PURPOSE:To detect only a target signal by a target detector by separating a signal responsive to a target from noise intrinsic for a CCD. CONSTITUTION:A video signal from a CCD is applied to a binary encoder 6 which produces ''1'' when the signal is higher than predetermined level and ''0'' when the signal is lower than predetermined level. The output signal from the encoder 6 is applied through a delay circuit 7 having predetermined time delay to one input of an AND gate 8. The output of the encoder 6 is applied directly to the other input of the AND gate 8. The AND gate 8 thus produces a signal responsive to a target signal only.
