ABSTRACT:
According to one embodiment, a video display apparatus includes a liquid crystal panel configured to display a video on a display area and light sources, each configured to be controlled respectively and to light in an illumination area into which the display area is virtually divided according as arrangement of the light sources. The apparatus includes a first calculation unit configured to calculate a second emission intensity corresponding to a small-area based on a video signal in a small-area, wherein the small-area is segmented area of the display area and smaller than the illumination area. The apparatus includes a second calculation unit configured to calculate a first emission intensity to control the light source from the second emission intensities and a control unit configured to light the light sources at the first emission intensities.
