Abstract
A method for processing an image includes inputting an image, generating a first mean luminance value and a second mean luminance value according to a plurality of pixels within a first luminance interval and a second luminance interval of the image, generating a first luminance threshold according to the first mean luminance value, setting a compensation parameter, generating a first compensation luminance value according to the first mean luminance value and the compensation parameter, generating a second compensation luminance value according to the first luminance threshold, the first mean luminance value, the second mean luminance value, and the compensation parameter, and adjusting luminance values of pixels within the a smaller compensation luminance value and a greater compensation luminance value according to the smaller compensation value and a comparison between the first compensation luminance value and the second compensation luminance value.
