Abstract

A circuit device includes a luminance analysis circuit and a dimmer circuit. The luminance analysis circuit performs luminance analysis on image data of an input image to output luminance information. The dimmer circuit determines light source luminance information indicating light-emission luminance of each of light source elements according to the luminance information. The dimmer circuit determines the light-emission luminance of the light source element from the luminance information of a pixel by using a weight corresponding to a distance between the pixel and the light source element. The dimmer circuit sets an attenuation degree of the weight with respect to the distance to a first attenuation degree when a global dimming parameter is a first value. The dimmer circuit sets the attenuation degree to a second attenuation degree higher than the first attenuation degree when the global dimming parameter is a second value smaller than the first value.
