PROBLEM TO BE SOLVED: To reduce the disorder of a half-tone display as to even a moving picture which is high in moving speed and to improve the moving picture false contour of video by selecting a predetermined light emission block for luminance adjustment, and adding or subtracting the selected light emission block for luminance adjustment to or from a source signal of successive pixels. SOLUTION: The state of an illumination block in a frame or field of two pixels positioned across successive pixels is detected, and the predetermined light emission block for luminance adjustment is selected according to the number of the successive pixels, the state of the two pixels positioned across the successive pixels, and the state of variation between frames or fields of the illumination pattern. Then display data 210 is supplied to a display device 100 through a luminance adjusting light emission block inserting means 200. Here, the inserting means 200 outputs the signal 220 generated by adding or subtracting the light emission block for luminance adjustment to or from the source signal according to whether or not there is variation of the source signal between frames. |
