Abstract
This paper proposed a novel RGB‐to‐RGBW mapping algorithm with minimized color distortion. This algorithm ensures that the color distortion of RGBW display is minimized by keeping the color coordinate remain unchanged from the original color. The proposed method primarily consists of three procedures. Step 1: Calculate the CIE chromaticity coordinates (x, y) and luminance (Y) of the input signal in the RGB display system. Step 2: Calculate the value of W0 based on the distance between the target color and the white point. Step 3: According to the color coordinate of the target color (x, y) and the color conversion model of multi‐primary‐color system, calculate the RGBW signal value of the target color in the RGBW display system. The comparison of test images shows that the algorithm is more effective than the traditional method in maintaining the saturation and hue of the original image.
