  • Patent number: 4090221
    Abstract: An input video signal is coupled to one input of a summing amplifier, to the input of a low-pass filter, and to one input of a movement detector. The output signal from the apparatus is delayed by one frame interval, and this delayed output signal is coupled to a second input of the summing amplifier and to a second input of the movement detector. The movement detector is of a type which generates a control signal to indicate movement in response to a plurality of frame-to-frame differences for adjacent picture elements. This control signal is utilized to selectively gate either the output from the summing amplifier or the output of the low-pass filter through to an output terminal.
