Abstract
PURPOSE: To ensure an easy and accurate white control through a simple operation by giving individual energizing control to more than one unit of the electronic gun in accordance with the primary colors as well as giving the energized control to the deflecting device according to the output of the vertical deflecting output circuit.
CONSTITUTION: Video gain varying circuit 3 varies the gain of the video signal which received the image detection, and the primary color signals are led out based on the output of circuit 3 and the video detection output. Then the vertical synchronous pulse sent from vertical oscillator circuit 10 is applied to vertical deflecting output circuit 11. And the energizing control is given to more than one unit of the electronic gun of the color picture tube individually in accordance with the primary color signals, and at the same time the deflecting device receives the energizing control according to the deflecting output given from circuit 11. Here, for a clip circuit 13 sets forcedly the vertical deflecting output signal to the DC level fixed period in response to the operation of switch 12 and also sets the gain of circuit 3 to zero. In this way, am easy and accurate white control is ensured a simple operation.
