Abstract

A method includes generating luminance setting data, luminance estimation data, maximum luminance data, and gradation setting data, and controlling a backlight panel and a liquid crystal panel based on the luminance setting data and the gradation setting data, respectively. The luminance setting data sets a luminance value for each light-emitting region of the backlight panel and is generated based on an input image. The luminance estimation data indicates an estimated luminance value of backlight for the input image with respect to each pixel of the liquid crystal panel and is generated based on the luminance setting data and luminance profile data. The maximum luminance data is generated based on the luminance estimation data. The gradation setting data sets a gradation value of each pixel of the liquid crystal panel for the input image, and is generated based on the input image, the luminance estimation data, and the maximum luminance data.
