Abstract
PURPOSE: To make it possible to solve the problem that a contrast and color saturation run counter to each other, by controlling the greatest value of an electron beam in accordance with the color saturation of a transmitted color TV signal.
CONSTITUTION: A chrominance signal is applied to input terminal 10, color saturation detection circuit 12 detects color saturation, and a signal shown in Fig. (b) is applied to level regulator circuit 13. As a result, a driving signal shown in Fig. (c) appears at output terminal 14. This driving signal drives a cathode-ray tube at a level high enough to obtain sufficiently-bright white or to fix an electron beam diameter large enough to obtain sufficient saturation. The level of this driving signal is varied according to the saturation to control greatest value of an electron beam, so that the problem that the contrast and color saturation run counter to each other can be solved.
