Abstract
A motion-adaptive scanning-line conversion circuit which converts part or the entirety of a first video signal into a second video signal. The circuit includes a data reducing circuit, such as a low pass filter and a decimator, which lowers the sampling frequency of the first video signal to reduce the amount of data in the first video signal. The conversion circuit can also include a detection circuit which detects the vertical edge of a stationary part of a picture represented by the reduced first video signal, and a motion detection circuit which determines the amount of motion of the pixels in the reduced first video signal. Based upon the detection of a vertical edge, a selection circuit selects between an output of an inter-field scanning-line conversion circuit and an intra-field scanning-line conversion circuit operating on the reduced first video signal and the first video signal, respectively.
