Method and apparatus for controlling television image processing based upon television program detection

摘要

A television image processing apparatus has a memory for storing television signals with respect to a predetermined frame image. The apparatus also has an arithmetic correlation circuit for calculating correlation quantity between television signals of each frame image applied thereto in real time and television signals of the frame image stored in the memory, and a control circuit for generating a control signal when the correlation quantity calculated by the arithmetic correlation circuit exceeds a predetermined value.
