Title:
COLOR VIDEO SIGNAL PROCESSOR
Document Type and Number:
Japanese Patent JPH02179187
Kind Code:
A
Abstract:
PURPOSE:To constitute the title processor of a small number of pins at the time of forming IC and to facilitate the miniaturization and the rationalization by providing a switch circuit means for selectively outputting the output of a first vertical filter and the output of a second vertical filter by a control signal. CONSTITUTION:For instance, a selecting signal of a control terminal 20 of a signal switching circuit 19 is selected, and a Y signal and a C signal are inputted to a first input terminal 1 and a second input terminal 10, respectively so that in a test point 21, a high frequency component of a vertical space frequency of a Y signal and a high frequency component of a vertical space frequency of a C signal can be fetched at the time of recording and at the time of reproducting, respectively. That is, the level is adjusted by switching outputs of each vertical filter of the Y signal and the C signal and outputting them to the test point. In such a way, the IC formation can be attained by a small number of pins, and the miniaturization and the rationalization are facilitated.
