Abstract

PURPOSE:To obtain a color signal generator which is small-sized and easy to operate, by switching a digital color control signal for controlling the lightness and chroma by some relation, and a signal for controlling the hue, by a signal showing the sample color phase, so that a color to be generated is varied. CONSTITUTION:A digital signal from a variable resistor VR1, etc. for controlling the lightness and chroma, and a signal from a variable resistor VR2, etc. for controlling the hue are inputted to an ROM203, and a signal of 8 bits of a 4 continuous sampling point portion. A clock of 4 times of a chrominance subcarrier from a terminal 204 is frequency-divided into 1/4 by a counter 205, becomes a signal for a sample hue, is supplied to a switching device 206, and 4 groups of signals are selected circularly from the ROM203. After that, a color video signal is outputted through a blanking gate circuit 208. As a result, the array of lightness and chroma saturation of the ROM203 is interlocked and varied in such a waveform as C0... C31. In this way, an area occupied by a control on the apparatus is reduced, also the workability is improved, and a digital video color signal is always set within the range where it allowed as a video signal.
