Abstract: An image processing method includes receiving an RGB data, converting the RGB data to an HSV data configured to include hue, saturation, and value compensating for the HSV data on a basis of a hue data of the HSV data, and converting the compensated HSV data to a compensated RGB data. The compensating of the HSV data includes reading out a compensation data corresponding to the hue data from a look-up table and compensating for the HSV data using the compensation data. The data are compensated on the basis of the hue in the HSV color space and the saturation and value are preserved, and thus the image, e.g., the memory color like the skin color, may be prevented from being distorted.

Abstract: A display panel is divided into multiple areas respectively driven by multiple drivers, and the multiple areas are adjacent to each other along a first direction. An object moves along the first direction between a first frame and a second frame and is displayed on the display panel. The moving speed of the object is compared with a reference speed. A main compensation frame is added between the first frame and the second frame. A first high speed compensation frame is added between the first frame and the main compensation frame when the moving speed is higher than or equal to the reference speed. A first low speed compensation frame is added between the first frame and the main compensation frame when the moving speed is lower than the reference speed, and the first low speed compensation frame is different from the first high speed compensation frame.
