ABSTRACT:
Chroma-signal processing system is disclosed wherein a color television signal is sampled at a frequency equal to a sub-carrier frequency multiplied by an integer, and chroma-components of the sampled signals are sequentially stored in a plurality of storage means for each of the sample points, and the chroma-signals are retrieved from the storage means while omitting portions of the chroma signals whereby accomplishing the chroma-signal processing with a fewer number of storage means. The system can be used to reduce the size of a displayed color image without introducing phase discontinuities into the chrominance subcarrier. The reduced image may then be inset into another color image displayed on a CRT. The system may also be used to reduce the subcarrier frequency of a chrominance signal.
