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 apparatus includes a display panel, a gate driver, and a gate driving control circuit. The gate driver is connected to the display panel, and generates gate signals for driving the display panel using a gate clock signal. The gate driving control circuit generates the gate clock signal using a gate on voltage and a gate off voltage, determines whether an operation environment is an abnormal temperature environment by comparing a first feedback gate signal with a second feedback gate signal, and adjusts a voltage level of the gate clock signal in the abnormal temperature environment. The first feedback gate signal is retrieved from the display panel while a first frame image is displayed on the display panel. The second feedback gate signal is retrieved from the display panel while a second frame image subsequent to the first frame image is displayed on the display panel.
