Abstract
A method of image enhancement in a video, comprises acquiring a luminance statistics of an image; determining a boosting curve according to a target brightness and a brightness of the image; determining an enhancing curve according to a saliency distribution of a pixel brightness derived from the luminance statistics, to the target brightness and a noise level of the image; blending the boosting curve and the enhancing curve based on an enhance level to generate a control curve; and enhancing the image based on the control curve; wherein the control curve enhances the brightness and a contrast of the image.
