Abstract
The present disclosure relates to a method and apparatus for image processing, comprising: transforming RGB luminance input values of each of pixels in an image into coordinate values in a uniform color space; moving the coordinates of each of pixels in the uniform color space a setting distance based on luminous efficiencies of RGBW and a replacement ratio of W; the setting distance being set so as to satisfy that a color difference between RGB luminance values transformed from the moved coordinate values in the uniform color space and the respective RGB luminance input values of each of pixels is less than a preset value, in order to maintain image quality; and the setting distance being set so as to satisfy that the minimum of the transformed RGB luminance values is greater than the minimum of the RGB luminance input values. In this way, power consumption is reduced.
