Abstract
PURPOSE: To make it possible to display a white balance if an object has a white part, by displaying the adjustment state of a white balance on a basis of the movement quantity of the position of a vertical line indicated on a 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. Meanwhile, video signals supplied to comparator 9 become gate pulses corresponding to the period of a part having a level higher than the set level determined by threshold determining element 8, and are outputted at every one vertical scanning period. The output of switch circuit 3 is supplied to switch circuit 5, and the output appears only during the period of the gate pulse above and is supplied to amplitude- pulse width modulator circuit 11. The output of modulator circuit 11 is supplied to differentiating and pusle shaping circuit 13, and obtained pulses are added to video signals, and they are displayed on the receiving tube screen.
