ABSTRACT:
There is provided a correlation between adjustment of luminance of a LCD and adjustment of luminance of a backlight. Luminance average value “Iave” is determined from display data. Luminance maximum value “I1max” in a macro area is determined from the display data. Luminance is adjusted with reference to luminance-transformed luminance. In luminance transformation, slope average “r1” in a range of 0≦I<Iave, slope average “r2” in a range of Iave≦I<I1max, and slope average “r3” in a range of I≧I1max establish a relationship of r1≧r2>r3in an area defined by a horizontal axis showing luminance “I” and a vertical axis showing luminance-transformed luminance “I#”.
