摘要:
A RGB-to-RGBW color converting system includes: a linearization section for linearizing inputted RGB values; a comparing section for comparing the linearized RGB values to obtain maximum and minimum values; a binarization section for performing a brightness binarization on the linearized RGB values to obtain a brightness binarization value; a gain value determining section for comparing a percentage of number of pixels corresponding to the brightness binarization value to all number of pixels in an image with a preset percentage to obtain a gain value; an output value calculating section for calculating RGBW output values according to the linearized RGB values, the maximum value, the minimum value, the gain value and the preset percentage. Accordingly, the addition of W sub-pixel unit would not result in the decrease of RGB output values, so that the color saturation can be improved while the whole brightness of image is maintained.
