Abstract

PURPOSE:To increase the color resolution with a simple circuit constitution, by picking up profile component of color from a color difference signal applied to a band limit filter and synthesizing it to a luminance signal. CONSTITUTION:An output of a color image pickup device 1 is inputted to a low pass filter 5 and a band pass filter 6 via a preamplifier 4. The luminance signal from the low pass filter 5 is inputted to a synthesizer 8 via a luminance process circuit 7. Red and blue difference signals are introduced at synchronizing detection circuits 13, 14 from the output of the band pass filter 6. Each color difference signal is inputted to a color encoder 18 via low pass filters 16, 17. The red difference signal is applied to a pickup circuit 19 to pick up the color profile component and inputted to a synthesizer 8. The profile component of color and luminance signal are synthesized at the synthesizer 8 and the carrier chrominance signal from the color encoder 18 is synthesized at the synthesizer 20.
