Abstract

PURPOSE:To obtain a luminance signal with high resolution, by forming an absolute signal of sum and difference signals between a picture signal and a signal delaying this picture signal by 1H period and subtracting the absolute value signal from the sum signal. CONSTITUTION:A signal from a color solid-state image pickup element 1 provided with a color filter is branched; one is applied to gate circuits 5 and 6, and another is applied to a gate circuit 7 via one H delay line 3. A Y picture element signal component is picked up at the circuit 5 and applied to an LPF9. The circuits 6 and 7 pick up Y+R and Y+B signal components and apply them to LPFs 10 and 11 via a switching circuit 8. One of the signals from output lines 2 and 4 is added and given to an output line 12 and another is given to an output line 14 via an absolute circuit 13 after subtraction. The signal difference between the output lines 12 and 14 is outputted through a BPF6.
