Filed: 1980-02-27
Abstract: PURPOSE:To increase the degree of color saturation, by making the first one horizontal scanning for index signal detection with the beam of a given low level in case of the reception of color signal and with the beam of noncolor video signal in case of the reception of black-and-white signal. CONSTITUTION:In case of n (where n is an integer of two or more) times of horizontal scannings with a selector switch control circit 23, switches 20, 21 are connected to terminal (a). When the signal during reception is a color signal, the switch 25 is connected to the terminal (a) with the output of a signal discrimination circuit 24, a given level of signal EDC is fed to an index tube 1, and the output of a photoelectric conversion element 16 is input to the switch 20 as the index signal without cross modulation. Taking n as 2, and when the circuit 23 is operated every one horizontal period, dark signal and color signal are alternately displayed every one horizontal period on the screen of the tube 1, but since the signal EDC can suppress the illumination of fluorescent substance up to the minimum level in which the index signal can be detected, the color saturation can be increased.
