First Claim
Patent Images
1. A television frame image detecting apparatus for detecting television signals representative of a predetermined frame image, said apparatus comprising:
- a memory means storing television signals with respect to a predetermined frame image at a representation point in each of divided areas of a screen for image;
a sampling means for sampling television signals of each frame image applied thereto in real time at said representation point in each of said divided areas of said screen;
an arithmetic correlation means for calculating correlation quantity between sampled television signals of each frame image and television signals of the predetermined frame image stored in said memory means; and
a control means for generating a control signal to be used for controlling at least one of recording start and recording stop in a video recorder when the correlation quantity calculated by said arithmetic correlation means exceeds a predetermined value.

Abstract
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.
