Abstract
A line generator (31) for receiving fields of pixel data sampled from a video input signal and for generating additional lines of pixel data so that the display frames will have more lines than the fields. The line generator (31) has a motion detector (31a) that determines, on a pixel by pixel basis, whether some part of the current field is in motion. A motion signal from the motion detector (31a) is used to select between outputs of two or more pixel generators (31b, 31c). One of the pixel generators (31b) provides pixel values that are better suited for display when the image is not in motion. The other pixel generator (31c) provides pixel values that are better suited for display when the image is in motion.
