摘要

A television receiver displays the picture information of an interlaced signal, such as a baseband NTSC signal, in a non-interlaced scanning format. The NTSC signal (130) is comb filtered in a line comb filter (15) to extract a luminance representative component signal (Yi). When no motion occurs in the picture scene, vertical detail (Yd) is added (33) and subtracted (39), respectively, from the luminance representative signal (Yi) to form first (Yb) and second (Ya) enhanced luminance signals, respectively. The first and second signals are time compressed (23) so that during each horizontal line interval (1H) of the baseband NTSC signal (130), both of the corresponding time compressed (Y2H) first and second signals can be displayed (43, 51) as consecutive non-interlaced scan lines, respectively, of the display (51). When motion is detected (37), vertical detail enhancement is diminished (41, 35) so that artifacts which may be more pronounced in the presence of motion, become less visible.
