摘要:
A color resolution compensator for a color television receiver improves the resolution of a reproduced color picture by mixing a high frequency component of a luminance signal to a color difference signal to generate a signal to be fed to the color demodulators of the television receiver. Various portions of the luminance signal and the color difference signal may be optimally selected in dependence upon various predetermined design parameters.
摘要:
A system for improving color picture qualities in which in response to the output signal representative of whether the transient portion of the luminance signal Y and the color difference signal (C-Y), where C is R, G or B, is in the same direction or in the opposite directions, the high-frequency component in the luminance signal is so controlled as to provide the correction signal which serves to improve the contour lines of the images in the reproduced color picture.
