摘要： A display device separates a size-reduced image into a plurality of sub-areas in such a manner that a sub-area farther away from the light sources becomes wider than a sub-area closer to the light sources; compares, in each of the sub-areas, the luminance values of each pixel in a direction perpendicular to the array direction; and selects a pixel having the greatest luminance value, thereby creating line information. The display device then compares a light distribution that is a synthesis of light radiation patterns of the light sources with a luminance distribution indicated by each line information and then adjusts the emission intensity of each of the light sources.

摘要： An image correction apparatus calculates a feature value indicative of an average brightness of an input image from the pixel values of the input image and determines a pixel value at a boundary for correcting each pixel of the input image to make it brighter or darker by using the calculated feature value of the input image. The image correction apparatus calculates, with respect to the pixel value of each pixel of the input image, an area for determining a contrast correction amount for a pixel value smaller than the pixel value at the determined boundary such that a pixel is to be made darker and calculates an area for determining a contrast correction amount for a pixel value larger than the pixel value at the determined boundary such that a pixel is to be made brighter, thereby correcting the contrast of the input image by using the calculated areas.
