Abstract
In an image processing device, for each of one or two or more picture elements among a plurality of picture elements, the one or two or more picture elements having an input grayscale value included in the input image data being equal to or less than a first predetermined value, the second panel data correction unit corrects the second aperture ratio of each of at least one pixel among the plurality of pixels, the at least one pixel facing the one or two or more picture elements, so that an actual transmittance gets closer to a theoretical transmittance, and the first panel data generation unit generates the first aperture ratio for each of the plurality of picture elements by dividing a normalized input grayscale value included in the input image data by a normalized luminance included in the panel luminance distribution data.
