Abstract

PURPOSE: To enable to eliminate false signal, by arranging the sampling frequencies of each chroma signal from green to blue, and making agreement in the transfer function to horizontal direction.
CONSTITUTION: The green signal G and the red and blue dot sequential signal R/B from the optical low pass filter 2 taking 1/2Px (where: Px is the arrangement pitch of horizontal video element) as the cut off frequency, and pick up elements 3G and 3RG, are the dot sequential differential signal R-GR (greeen signal to red signal) and B-GB (green signal to blue signal) from the subtractor 4. Those signals are fed to the carrier chrominance signal forming circuit 10 to form the carrier chrominance signal Sc. On the other hand, at the luminance signal forming circuit 20, high band component of green signal G is used to obtain the high band component YH, and the low band component YL is obtained through the use of the low band component of each chroma signal G to B so that it can be the same as the low band component as the luminance signal in NTSC system, and the signals YH and YL are synthesized 28 to obtain the luminance signal SY. Further, the carrier chrominance signal SC and the laminance signal SY are synthesized 29 to obtain the synthesized color video signal SO.
