A display apparatus to receive a picture signal containing information of a picture and to process the picture signal using at least an area distinguishing the picture from another picture includes a motion detector to detect whether there is a motion in the area of the picture signal, a hysteresis generator to output hysteresis information on each area according to a detected result of the motion detector from a previous frame up to a current frame, a moving picture detector to detect whether the picture signal is a moving picture signal or a still picture signal in the area on the basis of the hysteresis information, and a gradation level converter to convert the picture signal corresponding to the area into either a group of gradation levels for a moving picture to display the moving picture signal or a group of gradation levels for a still picture to display the still picture signal according to a detecting result of the moving picture detector. With this configuration, a false contour of a moving picture signal can be attenuated, thereby minimizing a flicker.
