Abstract

PURPOSE: To make it possible to discriminate whether a white balance is good or not if an object has a white part, by displaying the white balance adjustment state on a basis of the position for the reference line of an indication line indicated of the receiving tube screen.
CONSTITUTION: Color difference signals G-R signals and G-B signals are supplied to switch circuit 3 and are outputted alternately at every horizontal scanning period. The output of switch circuit 3 is supplied to switch circuit 5, and switch circuit 5 outputs the output during the period of pulses having the phase and the width in the vertical and horizontal scanning period corresponding to the center of the receiving tube screen and outputs a reference voltage in a period other than the period above. Amplitude-pulse width modulator circuit 8 outputs pulses which change the width according to the level of signals supplied from switch circuit 5. The output of modulator circuit 8 is supplied to differentiating and pulse shaping circuit 10, and obtained pulses are added to video signals, and they are displayed on the receiving tube screen.
