A video signal processing apparatus has an input terminal for receiving an input video signal and a delay line for delaying the input video signal. A first transmission circuit processes the video signal which has been delayed by the delay line and a first timer reversal circuit reverses the time sequence of the input video signal during a predetermined time period. A second transmission circuit processes the time reversed signal from the first time reversal circuit and a second time reversal circuit reverses the time sequence of the signal processed by the second transmission circuit. An adder circuit adds the signal processed by the first transmission circuit and the time reversed signal from the second time reversed circuit. A control pulse generator produces a control pulse sequence which inverts its level every predetermined period so as to control the first and second time reversal circuits. The output of the adder circuit serves as the output signal processing apparatus.
