VIDEO SIGNAL PROCESSING APPARATUS

摘要

The apparatus comprises a delay circuit (3) for delaying an input signal by a predetermined time. An operational circuit (4) conducts an addition or substraction operation between an output signal of the delay circuit and an input video signal. A nonlinear processing circuit (9) receives an output signal of the operational circuit (4) and generates two output signals. One output signal has a gain that decreases with an increase of the absolute value of the level of the output signal and becomes zero when the absolute value exceeds a specified value. A further operational circuit (2) conducts an addition or subtraction operation between the output signal of the nonlinear processor (9) and the input video signal. The operation result is output to the delay circuit (3).
