摘要： An image display apparatus for displaying images based on signals of an input image is provided. A backlight emits light. A liquid crystal panel modulates light emitted from the backlight. A emission intensity calculating unit calculates an emission intensity of the backlight such that a center value of a lightness range displayable on the panel defined depending on the emission intensity of the backlight substantially agrees with a center value between maximum and minimum values of lightness of each signal of the input image. A backlight controlling unit controls light emission of the backlight such that the light is emitted with the emission intensity. A signal correcting unit corrects each signal of the input image in accordance with the emission intensity. A liquid crystal controlling unit controls modulation of the liquid crystal panel based upon the corrected signals.

摘要： The liquid crystal panel displays a video in a display area by modulating light from the backlight including a plurality of light sources. The luminance value calculator calculates light source luminance values of the light sources based on an input video signal including signal values of pixels. The luminance distribution calculator calculates luminance distribution of light in illumination areas obtained by tentatively dividing the display area if the light sources emit light according to the light source luminance values. The representative value calculator calculates, based on the input video signal, a representative luminance value in each of divided areas obtained by dividing the display area. The signal corrector corrects the input video signal based on the luminance distribution according to a difference between a maximum value of the representative luminance values and an average value of the representative luminance values.
