Abstract

PURPOSE:To prevent production of color distortion based on an error relatively produced by sampling phase, by separately modulating the 2nd and 3rd color signals equal to the 1st color signal in the sampling phase. CONSTITUTION:Red R and Blue B signals from a CCD2 are converted into digital signals at an A/D converter 3 and fed to filters 6, after processing at processing circuits 4, and digital luminance signals YR, YB are picked up with red and blus signals CR, CB. After these signals CR, CB are processed digitally, the digital modulated chroma signal CRB is delayed for a given time, and it is synthesized with the digital luminance signal and also synthesized with the burst signal SB and composite synchronizing signal SYNC at the synthesizer 25. The green signal G output from the CCD1 is similarly synthesized with the digital video signal DVS2 at the synchesizer 103 to from analog standard television signal TVS.
