ABSTRACT:
A picture signal processing device for processing picture signals for displaying e.g., an enlarged picture, a contracted picture or a still picture. The picture signal processing device includes a motion detection unit for comparing the picture signal level of a pixel under detection in a first field or a second field together making up a frame, the picture signal levels of pixels lying close to the pixel under detection and the value of a variably set motion detection coefficient to one another for detecting the possible presence of motion in the picture of the pixel under detection. The first field is formed by every two scanning lines and the second field is formed by the remaining scanning lines. The picture signal processing device also includes a field interpolation unit for effecting intra-field interpolation of the picture signals of the pixel under detection on detection of the motion in the picture of the pixel under detection by the motion detection unit, and a detection coefficient setting unit for variably setting the motion detection coefficient.
