摘要： A video signal processing circuit of motion adaptive type includes a circuit for identifying motion of a picture in a video signal on the basis of a difference signal between at least a line signal appearing in an M-th field and a corresponding line signal appearing in an (M-1)th field so that, when a scanning line produced on the basis of the video signal is interpolated between scanning lines of the video signal to improve the picture quality, a signal for interpolating said scanning line is produced in a different manner depending on whether a portion of the video signal to the displayed is a still picture or a moving picture. The motion identifying circuit comprises a horizontal filter spreading the difference signal in the horizontal direction, a circuit delaying the output signal of the horizontal filter by one field after attenuation, a line memory delaying the output signal of the attenuating and delaying circuit by one line, and an output circuit generating a signal identifying the motion of the picture on the basis of the output signals of the horizontal filter, attenuating and delaying circuit and line memory.

摘要： A motion detector for a chrominance signal which is used with a TV receiver equipped with a video signal motion detector. This motion detector for a chrominance signal has a delay element for delaying the chrominance signal of a video signal by 1 frame period, a subtracter for subtracting the output signal of the delay element from the input signal thereof, an absolute value conversion circuit to which the output signal from the subtracter is inputted, and a smoother circuit to which the output signal from the absolute value conversion circuit is supplied. If the chrominance signal of video signals on two consecutive frames are the same, the output signal of the subtracter becomes zero. If the chrominance signals of video signals on two consecutive frames are different, the output signal of the subtracter takes a positive or negative value. The negative value signal is converted into a positive value signal by the absolute value conversion circuit. A signal is outputted from the smoother circuit only when the chrominance signals of video signals on two consecutive frames are different. This outputted signal is a chrominance signal motion detection signal.The luminance signal contained in a video signal is removed from the video signal using a comb-type filter.

A signal is outputted from the smoother circuit only when the chrominance signals of video signals on two consecutive frames are different.
