Classification: CPC G | IPC G

Claim 1:
2. The image processing device according to claim 1,
the display panel unit further including a backlight facing the second liquid crystal panel and having a plurality of light-emitting regions,
the image processing device further comprising:
a backlight data generation unit configured to generate backlight data for controlling each of a plurality of normalized luminances of the plurality of light-emitting regions based on the input image data;
a backlight data correction unit configured to correct the backlight data; and
a backlight luminance distribution generation unit configured to generate backlight luminance distribution data of the backlight based on the backlight data after correction,
wherein the second panel luminance distribution generation unit generates the panel luminance distribution data based on the second panel data after correction and backlight luminance distribution data, and
for each of one or two or more light-emitting regions among the plurality of light-emitting regions, the backlight data correction unit corrects the normalized luminance included in the backlight data to set the normalized luminance included in the backlight luminance distribution data to be greater than the normalized input grayscale value included in the input image data.
