Abstract
In a method for processing an image, statistical information is obtained by performing histogram statistics on an image frame included in a video sequence. An overall compression ratio of the image frame and mid luminance information of the image frame are obtained based on the statistical information. A compression curve is obtained based on the overall compression ratio and the mid luminance information. Dynamic range compression is performed on the image frame by adjusting a shape of the compression curve based on the overall compression ratio, the mid luminance information and adjustment ratios.
