In one embodiment, an image display apparatus is disclosed. The apparatus includes a liquid crystal panel, a backlight, a calculation unit, a reference unit, a multiplier unit, and a determination unit. The backlight includes light sources illuminating the liquid crystal panel unit. The calculation unit calculates a representative value of relative luminances of pixels in the each of small regions into which the display region is divided. The reference unit refers to prestored lighting pattern data items for the light sources. The multiplier unit multiplies, for each of the small regions, the referred lighting pattern data item by the representative value. The determination unit determines emission intensities of respective light sources based on multiplication results of the multiplier unit.
