Abstract:
1. A liquid crystal display device for displaying video data, comprising: a detection circuit for detecting a histogram of gradations for each of divided regions based on video data which is inputted, each divided region including a plurality of gradations; a determination circuit for determining at least one of a plurality of divided regions of higher generation frequency of gradation on the histogram than that of other divided regions based on the histogram; a correction circuit for correcting the video data so as to make a luminance characteristic of the at least one of the plurality of divided regions of higher generation frequency of gradation on the histogram more abrupt than a luminance characteristic of the other divided regions; and a liquid crystal display panel for displaying the corrected video data; wherein a width of the divided region becomes narrower as a light transmittance of a liquid crystal of the liquid crystal display device becomes greater.
