Abstract
A circuit device includes a luminance processing circuit and a color correction circuit. The luminance processing circuit computes lighting luminance information indicating luminance at which a target pixel of a display panel is illuminated by a plurality of light source elements, based on light source luminance information indicating luminance of light emitted by each of the plurality of light source elements and attenuation rate distribution information indicating an attenuation rate distribution of light with respect to a distance between each of the light source elements and each of pixels. The color correction circuit performs color correction on input image data based on the lighting luminance information. The luminance processing circuit computes the lighting luminance information by disabling light source luminance information of virtual light source positions where the plurality of light source elements are not arranged in a computing grid used for computation of the lighting luminance information.
