Abstract: <P>PROBLEM TO BE SOLVED: To improve an afterimage reduction effect when there is a motion of an image with a little luminance difference or when there is a motion of an image with an indistinct contour.  <P>SOLUTION: An image signal V<SB>-1</SB>' of a preceding field is subtracted from an image signal V<SB>0</SB>of a current field by a subtractor 403 to obtain a subtracted signal including noise and motion components. A signal SL of a low frequency band and a signal SH of a high frequency band are extracted from the subtracted signal. Absolute values of the signals SL and SH are taken and the absolute values equal with or greater than a predetermined value are limited to obtain motion quantity detecting signals MDL and MDH. The signals MDL and MDH are supplied to extension circuits 407 and 412 to extend the signals horizontally or vertically at least. By the extension, even when the signals MDL and MDH are small in a motion starting part, they can be enlarged.
