Abstract:
1. An image processing method, comprising: converting an image signal to an original luminance value, an original first chroma value and an original second chroma value; adjusting the original luminance value to a adjusted luminance value, wherein the adjusted luminance value is larger than the original luminance value as the original luminance value is larger than a threshold, and the adjusted luminance value is less than the original luminance value as the original luminance value is less than the threshold; linearly adjusting the original first chroma value and the original second chroma value to a adjusted first chroma value and a adjusted second chroma value according to an original vector between the original first chroma value and the original second chroma value and a white point in a color gamut; and reconverting the adjusted luminance value, the adjusted first chroma value and the adjusted second chroma value to a adjusted image signal, and outputting the adjusted image signal.
