Video signal processing apparatus for an improved definition television receiver

摘要

Extracting circuit for extracting the reinforcement signal from the received broadcasting signal; an input unit for inputting the video signal of the main picture portion and the extracted reinforcement signal; vertical filtering processing circuit (22) for smoothing a continuity in the vertical direction of the video signal; memory (25) for storing the video signal; and controller for controlling the memory in a rule such that in a camera mode, the reinforcement signal is stored into said storage means together with said video signal and a scanning line interpolating process using the reinforcement signal is executed and, in a film mode, the inputted video signal is delayed by a predetermined period of time.
