Patent ID: 8760384

Claim:
An image display apparatus for displaying images based on an input image, comprising: a backlight configured to emit light; a liquid crystal panel configured to modulate light emitted from said backlight to make an image display; a backlight luminance calculating unit configured to calculate a light-emission luminance of said backlight such that a center value of a luminance range displayable on said liquid crystal panel defined depending on the light-emission luminance of said backlight substantially agrees with a center value of luminances of each pixel forming the input image; a backlight controlling unit configured to control light emission of said backlight so that the light is emitted with the calculated light-emission luminance; a luminance correcting unit configured to correct the luminances of each pixel in the input image in accordance with said calculated light-emission luminance; and a liquid crystal controlling unit configured to control modulation of said liquid crystal panel based upon the corrected input image, wherein said backlight luminance calculating unit multiplies a center value of the luminances of said each pixel by a square root of a display dynamic range of said liquid crystal panel to obtain the light-emission luminance of said backlight.
