Patent ID: 8723848

Claim:
An image display apparatus, comprising: a displaying unit that includes plural display elements; plural light sources that emit light for a predetermined display element among the plural display elements; a color filter that blocks predetermined light among light emitted by the plural light sources from being emitted to the predetermined display element; a controlling unit that controls an image displayed on the displaying unit in accordance with a gradient of an input image data; a detecting unit that detects a luminance heterogeneity or a color heterogeneity caused by a light leak of a light source other than a light source corresponding to the color filter on the image displayed on the displaying unit, the detection of luminance heterogeneity or color heterogeneity including determining a luminous efficiency at adjacent light sources of the display element; determining a light leak amount for the adjacent light sources based on the determined luminous efficiencies, and determining whether the light leak amount is larger than a permissible value of light leak amount; and an identifying unit that identifies a display element, among the plural display elements, in which the luminance heterogeneity or color heterogeneity detected by the detecting unit occurs, wherein the controlling unit performs a control that makes a mixture of light from the plural light sources that emit light to the display element identified by the identifying unit substantially become white.
