Abstract

PURPOSE: To make it possible to adjust a video circuit in a simple process with requiring only brightness adjustment of a video signal amplifier circuit without requiring contrast adjustment by using only DC components as video signals.
CONSTITUTION: A DC voltage higher than the AGC voltage is applied to AGC circuit 18 from the second rectifier circuit 14 to set video intermediate frequency amplifier circuit 3 to a saturation state. Thus, even if any signal is inputted to video intermediate frequency amplifier circuit 3, no signal components are inputted to video detection circuit 4, and only fixed DC components are outputted as video detection output. Therefore, DC components as detection output are amplified by video signal amplifier circuit 5 as they are, and only DC components are outputted as an output signal. As a result, only DC components are applied to voltmeter 16 at an adjustment time, and indication is stabilized.
