Patent ID: 8842109

Claim:
An image display device for displaying an image that includes a plurality of frames in a display panel that includes color filters of a plurality of colors by respectively controlling emission ratios of a plurality of light sources that emit light of colors respectively corresponding to the color filters, comprising: a detecting unit that detects, for the respective frames of the image, halo phenomenon caused in the display panel due to a light leakage from the light source of the color other than the color corresponding to the color filter; a detection restricting unit that restricts detection performed by the detecting unit to detection of the halo phenomenon in a part of the display panel; and a control unit that controls the emission ratios of the light sources and makes color of the light to be closer to white by lowering chroma of the light, wherein the light corresponds to mixed light from the plurality of light sources and to be made incident upon the color filters, when the detecting unit detects the halo phenomenon in a plurality of continuous frames.
