ABSTRACT:
A display apparatus that displays a picture based on a video signal, including a moving picture determiner that determines whether the video signal is used for displaying a moving picture; a moving picture gradation level table that stores information about a moving picture gradation level group for displaying the moving picture; a still picture gradation level table storing information about a still picture gradation level group including a predetermined number of gradation levels in consideration of a gradation level difference between the gradation levels of adjacent gradation levels in the case where the gradation level difference between the adjacent gradation levels of the moving picture gradation level group is larger than a predetermined reference gradation level difference; and a gradation level converter that converts the video signal to have the gradation level of the moving picture gradation level group or the still picture gradation level group according to results of the determination. With this configuration, a false contour is attenuated and a flicker is avoided in a moving picture.
