FIELD: physics.
SUBSTANCE: image display device includes the first light modulation device which includes a plurality of display pixels and modulates light based on the input first image information; a lighting unit which includes a plurality of light adjustment elements and emits an adjusted light to the first light modulation device; an illumination distribution storage unit storing an illumination range in which light emitted from the light adjustment elements illuminates the display pixels of the first light modulation device; and a decision unit for the light adjustment information which decides on the light adjustment information for controlling the light adjustment elements of the lighting unit based on the value of the first image information feature, corresponding to the display pixels of the illumination range stored in the illumination distribution storage unit.
EFFECT: increased brightness of the image.
