Abstract:
1. A display device comprising: a plurality of light sources that are aligned in an array direction such that areas irradiated by the light sources overlap with each other; an image display area that includes a plurality of pixels being aligned in a second perpendicular direction being perpendicular to the array direction; a separating unit that separates the image display area into a plurality of sub-areas with respect to a direction parallel to the array direction; a comparing unit that compares luminance of each of the plurality of pixels being aligned in the perpendicular direction with respect to each of the sub-areas made by the separating unit and selects a pixel, from each of the sub-areas, having a greatest luminance from among the plurality of pixels compared to create line information; and a control unit that creates line information for the sub-areas based on the pixel selected for each respective sub-area, the line information indicating a luminance distribution by aligning the pixels selected in the array direction, the control unit creating a synthesized light distribution of the light sources by using light radiation patterns of the light sources, the control unit controlling an amount of light from each of the light sources in accordance with a comparison result of the luminance distribution of the created line information and the synthesized light distribution of the light sources.
