Title: Contour compensating circuit
Inventor: IKETANI KOHEI
IPC: H04N5/208
Filed: 1990-04-25
Abstract: PURPOSE:To execute suitable contour compensation over an entire screen by enlarging the contour compensation amount of the contour compensating circuit for a video camera or the like at the end part of the screen rather than at a central part. CONSTITUTION:In a horizontal contour compensating circuit 13, an input luminance signal is inputted from an LPF 12 through the non-inverted input terminal of a differential amplifier 3 and a delay circuit DL2 to the inverted in terminal. The output of the amplifier 3 becomes a signal for compensating the contour and is supplied through a voltage controlled amplifier VCA 4 to an adder 17. On the other hand, the control signal of the VCA 4 is generated by an address counter 5, ROM 6 and D/A 7. Every time a horizontal synchronizing signal is inputted, the counter 5 is reset and repeatedly counts clocks. Thus, a position signal in the direction of a horizontal scanning line is generated. The counted value is inputted to a ROM 6 and the ROM 6 outputs a control signal at a level corresponding to the counted value. This signal is set so as to be large at the end part of the horizontal scanning line and to be small at the central part.
