ABSTRACT:
A scene change monitor includes a camera (12) for monitoring a given scene. The camera (12) is operable to sequentially generate frames (18) of visual information, which frames are then divided up into pixels and the value of the pixels for each frame accumulated in an accumulator (25). The accumulator (25) provides on the output thereof a frame value for each frame (18) and stores this value in a register (22). A difference generator (24) is operable to generate the difference between select ones of the registers (22) for select ones of the frames (18) and generate a difference value for input to a comparator (26). The comparator (26) compares the difference value to a scene change threshold and, if it exceeds this value, a VCR activation signal is generated for turning a VCR (16) on to record the scene.
