Abstract: A display apparatus includes a local dimmer, an image compensator, a display panel and a light source. The local dimmer is configured to generate a dimming signal representing a degree of dimming for a light source block based on input image data. The image compensator is configured to determine a grayscale gain based on input grayscale value of the input image data and the dimming signal and to compensate luminance of the input image data based on the grayscale gain. The display panel is configured to display an image based on the compensated input image data. The light source is configured to provide light to the display panel based on the dimming signal.

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 translation: 一种图像处理方法包括：接收RGB数据，根据HSV数据的色相数据，将RGB数据转换成HSV数据，HSV数据被配置为包括HSV数据的色相，饱和度和值补偿，并且将经补偿的HSV数据 到补偿的RGB数据。 HSV数据的补偿包括从查找表读出与色调数据对应的补偿数据，并使用补偿数据补偿HSV数据。 基于HSV颜色空间中的色调补偿数据，并且保持饱和度和值，因此可以防止像皮肤颜色的图像，例如存储器颜色变形。
