PURPOSE:To improve a resolution, to minimize the generation of a moire and to increase a sensitivity by transmitting all color lights with a first color filter, transmitting the color light only of the specified spectrum area with a second color filter and transmitting the color light and other color light to transmit the second color filter with a third color filter. CONSTITUTION:The W filter of a mosaic color filter 1a of a solid-state image pickup element 2 transmits a red light component, a green light component and a blue light component, a Ye filter transmits the red light component and the green light component and a G filter transmits the green light component only. A picture element signal read from signal lines S1 and S2 of the element 2 and a picture element signal to pass through 1H delaying signals 3 and 4 to delay the signal only for one horizontal scanning time are inputted respectively through computing elements 6, 7 and 8 to modulators 12 and 13 and an adder 14. By an encoder 16, a 2B signal from the adder 14, a 2R signal from a computing element 13 and a 2G+1.5R+0.5B signal from an LPF 11 are processed and outputted from an output terminal 17 as the video signal of the prescribed form.
