Abstract

PURPOSE:To provide a constitution in which an LPF in chrominance signal frequency band or a division circuit is not necessary and to make the constitution inexpensive by multiplying outputs from color separation circuits with coefficients that satisfy specific conditions, and adding them with each other for weighting. CONSTITUTION:The data of the image of an object which is spatially modulated by color filters is converted to electrical signals by an image pickup element 111, subjected to a pre-amplifier 112, then W and G lines are synchronized by a one-H delay line 113 as well as Cy and Ye lines similarly. The color separation circuit 114 performs a W-Cy-arithmetic operation and outputs a result. Color separation circuits 115-117 executes similar operation. A coefficient computing element 118 holds Cy level and Ye-level at the time of photographing the object in achromatic color, and executes prescribed operation based on said levels, to output coefficients rK1, rK2, bK1, bK2. These coefficients are inputted to multipliers 119-122, then to adders 123, 124 in respective pairs, and thus an R-signal and a B-signal generated. A G-signal is obtained by a sample-hold circuit 128 by selectively sample-holding G-picture elements.
