A display apparatus comprising: a display unit adapted to display an image corresponding to input image data on a display surface; an acquisition unit adapted to acquire a brightness of the image displayed on the display surface by said display unit; and a controller adapted to control said display unit so as to reduce a difference between the input image data and the image displayed on the display surface by said display unit, based on the image data input to said display unit, and the image acquired by said acquisition unit, wherein said controller estimates a ratio of an amount of light which forms the image displayed on the display surface by said display unit, is reflected by an object different from the display surface, and enters the display surface again, to a total amount of light which forms the image, based on an average of brightness values exhibited by the image data input to said display unit, and a brightness of the image displayed on the display surface, and wherein said controller controls said display unit to display the image after correcting the input image data, based on the estimated ratio.
