Abstract
On the basis of the image data obtained by the image data acquisition section, a target luminance calculation section calculates a target luminance, which is a target value for the luminance of emitted light for each segment region. An inverse filter acquisition section acquires an inverse filter of a light emission distribution function which represents light emission distribution characteristics of the light source for each segment region. A setting value calculation section calculates a setting value for the luminance of emitted light of the light source for each segment region by performing a convolution operation on the target luminance for each segment region with the inverse filter. On the basis of the setting value for each segment region calculated by the setting value calculation section, a light source control section controls the luminance of emitted light of the light source for each segment region.
