Abstract: In a motion detection circuit, a difference signal between the video and one-frame delayed video signals is generated Edge signals are generated from the video and delayed video signals. Motion in a target pixel is judged from the interframe difference signal according to the edge signals. A motion judging circuit further includes an LPF and a selector for supplying an output of the LPF or the difference signal. The motion judging circuit includes a polarity deviation detecting circuit for judging the motion as moving in the presence of agreement of the polarities of all pixels at any of peripheral areas around the target pixel. The size of the peripheral areas are controlled.

Abstract: A counter counts the frame counts n of a video signal. A delay for generating a delayed video signal delayed by one frame. A motion detector detects a motion from the video and delayed video signals. A circular coefficient generator generates coefficients k and 1−k according to the detected motion. A first circuit generates a first circulation signal from the video signal according to n, k, and a pre-determined value N. A second circuit generates a second circulation signal from the delayed video signal according to k and n. A adder adds the first circulation signal to the second circulation signal. 0≦k≦1. In the first circuit, a first multiplier multiplies (1−k) by N which is a natural number more than one, a second multiplier multiplies an output of the first multiplier by the video signal, and a first switch outputs the video signal when n≦N and outputs an output of the second multiplier when n<N, to generate the first circulation signal.

Abstract: An interframe difference signal is generated from the video signal and its one-frame delayed video signal. A filter removes a carrier color signal from the interframe difference signal to output the interframe difference luminance signal. A first motion judging circuit judges a motion in the video signal at a target pixel from the interframe difference luminance signal to output a first motion judging result in accordance with a first edge detection signal. A second motion judging circuit judges a motion in the video signal at the target pixel from a luminance signal and the carrier signal in the interframe difference signal to output a second motion judging result in accordance with a second edge detection circuit. The first and second motion judging results are combined. A majority determining circuit determines majority of the combined result from adjacent Q pixels in accordance with a third edge detection signal.
