ABSTRACT:
An image processing method for a liquid crystal display device includes: calculating first difference gradation, which is a difference between predicted attainment gradation and input gradation, the predicted attainment gradation being a predicted value of gradation which respective pixels of the liquid crystal display attain after one frame period after the respective pixels are driven to display a first frame, and the predicted attainment gradation being stored in a storage unit which stores the predicted attainment gradation, and the input gradation being gradation of a second frame which is displayed after the first frame; multiplying the first difference gradation by an enhancement coefficient; calculating enhanced gradation which is a sum of the first difference gradation multiplied by the enhancement coefficient and the predicted attainment gradation; calculating second difference gradation which is a difference between the enhanced gradation and the predicted attainment gradation; multiplying the second difference gradation by a correction coefficient; and updating the value of the predicted attainment gradation stored in the storage unit based on a sum of the second difference gradation multiplied by the correction coefficient and the predicted attainment gradation.
