Abstract
An image processing device includes an equation establishing unit, a calculating unit, a determining unit, a color space transformation unit, a first adjusting unit, a 3D LUT establishing unit, and a compensating unit. By the color space transformation equation plus a compensation value in advance for compensating color temperature of each gray level of the display screen, thus variation of the color temperature between low gray level and high gray level is significantly reduced and the display quality is highly promoted. Furthermore, the 3D LUT obtained by the compensated color space transformation equation can be used to compensate image parameters of pixels of a display panel so as to optimize the image performance of the display panel.
