Image display apparatus and image display method

摘要

An image display apparatus includes: a luminance modification unit configured to modify the luminance setting value so as to make a luminance difference between adjacent partial regions of a back light smaller; a luminance distribution calculation unit configured to calculate a predicted value of luminance distribution of light incident on a liquid crystal panel from the back light on the basis of the modified luminance setting value; a liquid crystal transmittance correction unit configured to correct an optical transmittance of the image signal at each pixel of the liquid crystal panel on the basis of the image signal and the luminance distribution; a back light control unit configured to control the back light on the basis of the modified luminance setting value; and a liquid crystal control unit configured to control the liquid crystal panel so that the transmittance of the image signal becomes the corrected optical transmittance.
