Abstract
An image display method includes generating luminance data, applying a special filter to the luminance data, generating luminance setting data, generating gradation setting data, and controlling a backlight based on the luminance setting data and a liquid crystal panel based on the gradation setting data. The luminance data indicates a luminance value for each of light-emitting regions of the backlight based on a maximum gradation value among gradation values of image pixels of an input image that correspond to the light-emitting region. The special filter is applied such that, with respect to each light-emitting region, a difference of the luminance value thereof from the luminance values of neighboring light-emitting regions decreases, and the luminance setting data is generated therefrom. The gradation setting data sets a gradation value of each pixel of the liquid crystal panel, and is generated based on the input image and the luminance setting data.
