Abstract
A display apparatus includes: a display that displays an image; a receiver that receives input signals corresponding to an input image; a surrounding environmental data processor that determines a surrounding environmental light condition including information representing a brightness of surroundings of the display apparatus; a backlight illumination ratio determiner that determines, for each of a plurality of areas set on the display, an illumination ratio of a backlight of the display based on the input signals and the surrounding environmental light condition; and a display controller that causes the display to display the input image by illuminating the backlight of the display based on the illumination ratio, wherein the backlight illumination ratio determiner determines the illumination ratio so that areas corresponding to a high tone range are assigned an illumination ratio of greater than or equal to an illumination ratio threshold value, the high tone range including input signals having a signal value of greater than or equal to a first signal threshold value.
