PROBLEM TO BE SOLVED: To enable compensating pseudo contour having no feeling of incompatibility even if the line of sight of an observer does not follow movement of a picture and to improve picture quality for animation by adding or subtracting a pseudo contour compensation signal to/from a picture signal only for fast movement. SOLUTION: A value of centroid is obtained with a pixel unit from picture signals of field memories 103, 104 with, a value of difference of centroid between a preceding field and a succeeding field is compared with the reference signal by a comparing circuit 109, when magnitude of difference of centroid is larger than the reference signal, a pseudo contour compensation signal generating circuit 110 is operated. When it is smaller, a value of 0 is outputted from the pseudo contour compensation signal generating circuit 110. A compensation signal is added or subtracted to/from a picture signal from a field memory 104 being a picture signal of the succeeding field by an adding/subtracting circuit 112, stored in a field memory 113, read out by a read-out circuit 114 with timing being adjusted to a display time of a display device, and sent to a display device 117 as a picture signal output 115. |
