Display control device, a display device and a display control program

Display device (1), the light control unit for changing the light transmittance or reflectance for each pixel (10), the light control unit and a plurality of light sources for emitting light to (10) (11), stored in advance based on the light emission pattern data (32) of each light source, and light emission distribution calculating unit in which each light source (11) calculates the light emission distribution when illuminated with light emission intensities are set to respectively, calculated by light emission distribution calculating section was provided with the light emission distribution luminance, and a luminance comparing unit that compares the brightness of the image to be displayed, and an adjustment amount determining unit that determines an adjustment amount of the emission intensity of each light source based on the comparison result of the luminance comparing unit. According to this embodiment, the light emission distribution obtained by combining the light emission pattern of each light source is compared with the image to be displayed, so it was decided to determine the emission intensity of each light source, a relatively small number of light sources emitting pattern even in an inexpensive display device being arranged to overlap, the supply amount of light to the black parts of the image dynamically lowered, thereby improving the contrast.
