Filed: 1985-11-20
Abstract: PURPOSE:To control automatically an image to have picture quality easy to see against the change of an APL by providing a series circuit consisting of a diode and a resistor between the picture quality control input terminal of a video signal process IC and an ABL voltage generating terminal. CONSTITUTION:It is assumed that a picture quality adjusting volume 6 is set at an intermediate point. When an average picture level (APL) is high, a potential at point A (ABL potential) is lowered with the increase of a current at a fly-back transformer 1, and an automatic picture quality adjusting diode 5 is turned off. As a result, the potential inputted to the picture quality control input terminal (1) of the video signal process IC7 is decided with the picture quality adjusting volume 6. On the other hand, when the APL is lowered, the potential at point A rises, and the diode 5 is turned on. As a result, since the potential at the control terminal (1) of the video signal process IC7, a picture quality circuit within the IC7 is controlled to a sharp side.
