<p>The present invention is to perform display with high color reproducibility by a display device that performs area active drive. An LED output value calculating unit (151) obtains LED data (33) representing the luminances upon light emission of LEDs provided for respective areas, based on an input image (31). A display luminance calculating unit (152) calculates a luminance image (41) including display luminances for the respective areas, based on the LED data (33) and a luminance spread filter (155). An LCD data calculating unit (154) determines temporary light transmittances of display elements of a liquid crystal panel based on an input image (42) delayed by a frame memory (153) and the luminance image (41), and obtains liquid crystal data (32) representing light transmittances such that, when a highest value of temporary light transmittances for respective colors exceeds 1, values obtained by dividing each of the temporary light transmittances by the highest value are used as light transmittances, and when the highest value does not exceed 1, the temporary light transmittances are used as light transmittances. By this, even if there is a color with insufficient luminance, since the ratio between the colors does not change, color reproducibility increases.</p> |
