Abstract:
A local failure of display video is suppressed. An LED data calculating portion that generates an approximate curve obtained by approximating the distribution of values of an input image, the approximate curve whose amount of change is less than or equal to a predetermined value, and calculates LED data based on the generated approximate curve and a liquid crystal transmittance calculating portion that calculates the liquid crystal transmittance based on the input image and the approximate curve generated by the LED data calculating portion are provided.
