Claim 0:
1. An image processing device causing a display panel unit to display an image, the display panel unit including a first liquid crystal panel including a plurality of picture elements and a second liquid crystal panel facing the first liquid crystal panel and including a plurality of pixels, the image processing device comprising:
a second panel data generation unit configured to generate second panel data for controlling a second aperture ratio of each of the plurality of pixels based on input image data;
a second panel data correction unit configured to correct the second panel data;
a second panel luminance distribution generation unit configured to generate panel luminance distribution data of the second liquid crystal panel based on the second panel data after correction; and
a first panel data generation unit configured to generate first panel data for controlling a first aperture ratio of each of the plurality of picture elements based on the input image data and the panel luminance distribution data of the second liquid crystal panel,
wherein, for each of one or two or more picture elements among the plurality of picture elements, the one or two or more picture elements having a normalized 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, to offset an amount of deviation of an actual transmittance of the picture elements from a theoretical transmittance of the picture elements, and
the first panel data generation unit generates the first aperture ratio for each of the plurality of picture elements by dividing the normalized input grayscale value included in the input image data by a normalized luminance included in the panel luminance distribution data.
