Abstract
When first and second region-processing sections (510, 520) calculate in parallel backlight luminances required for an input image halved by a regional image division section (505) included in an area-active drive processing section (5) of a liquid crystal display device, LED data (Db1, Db2) are exchanged for each other, allowing reference to backlight luminances not calculated for one region but calculated for the other region. As a result, when an area is illuminated by surrounding backlight sources, the actual display luminance can be calculated correctly. Thus, pixel display can be provided with correct display tones across the entire screen, thereby preventing a reduction in display quality.
