Abstract

PURPOSE:To omit the adjusting operation for variance compensation, by applying an primary color signals of red, green and blue to a multiplexer, making dot sequencial processing, and simultaneously processing the dot-sequentialized signal at every primary signal. CONSTITUTION:Primary signals R, G, B synchronized at a matrix circuit 4 are applied to a multiplexer 10 and are again converted into R, G, B point-sequential signal Sx, and this signal Sx is applied to a white balance adjusting circuit 5. A control circuit 20 outputs control signals PR-PB to make gain control for the adjusting circuit 5 in time division. The signal Sx adjusted with white balance is applied to a process amplifier 6 to process the signal Sx, i.e., dot-sequential primary color signal R-B commonly, and the output is applied to a simultaneously processing circuit 30 to be converted into a simultaneous signal. After the conversion, it is applied to a matrix circuit 7 to form a luminance signal and a pair of color difference signals, and they are applied to an encoder 8 to form a video signal.
