Abstract

PURPOSE: To make it possible to display a clear pattern with easy discriminations of a pattern on a screen and its shape in case of the use of either color or black-and- white cathode-ray tube, by varying the level of a luminance signal corresponding to various color signals.
CONSTITUTION: On the basis of a reference signal for obtaining various color signals and a luminance signal from decoder 16, color signals are obtained by mixer 31 and then mixed by mixer 32 with the luminance signal and synchronizing signal 33 to obtain a video signal. The luminance-signal level of this video signal is varied differentially by luminance-level adjustment circuit 15 corresponding to various color signals.
