Abstract
Each of image data sorted so as to correspond to divided areas respectively is stored in an in-area image memory. A maximum luminance extracting section extracts the maximum luminance value therefrom and records it onto the maximum luminance storage section. In accordance with the maximum luminance value that is thus stored in the maximum luminance storage section and that each of the areas has, a BL candidate value calculating section and a BL luminance difference adjusting section determine an emitted-light luminance in a target area such that a difference between the backlight luminance in the target area and the backlight luminance in its adjacent area is not more than a tolerance value.
