Abstract
A subframe data generation unitgenerates brightness data Ew, Er, Eg, Eb of four colors by obtaining distributed brightness with regard to each pixel based on brightness data Dr, Dg, Db of three colors, the distributed brightness being brightness of a white subframe, and obtaining brightness of red, green, and blue subframes with regard to each pixel based on the brightness data Dr, Dg, Db of three colors and the distributed brightness. The subframe data generation unitobtains the distributed brightness by setting an initial value of the distributed brightness to a maximum value that the distributed brightness can take, and then performing adjustment processing for reducing a difference between the distributed brightness of adjacent pixels. With this, a flicker phenomenon occurring at an edge portion of a display image is suppressed.
