- 1 - Abstract: A color television signal processing system converts a scanning signal sequentially scanned in the transmitter into an interlace-scanned television signal in order to obtain a high-quality color television picture. The system is arranged to detect information related to picture motion and concerning a spatio-temporal frequency characteristic, and to control the characteristic of a spatio-temporal filter for generating a luminance signal on the basis of this information and then to transmit the signal expressing this information multiplied with the color television signal. The arrangement achieves improved picture quality, especially for a moving image.
