Kind Code:
A1
Abstract:
Provided are an image brightness processing method and apparatus, and an image processing method and apparatus. The image brightness processing method comprises: dividing an image to be processed into a plurality of sub-regions, and acquiring brightness adjustment information of each of the sub-regions; according to the brightness adjustment information, determining a brightness adjustment parameter of each of the sub-regions; and performing brightness adjustment on each pixel in the image according to at least one of the following objects, so as to perform image brightness processing: a first brightness adjustment parameter of a first sub-region, and a second brightness adjustment parameter of a second sub-region, wherein the first sub-region is a sub-region where the pixel is located, and the second sub-region is one or more sub-regions adjacent to the first sub-region. According to the embodiments of the present invention, the problem in the related art of the poor imaging quality of a terminal due to the fact that the terminal is limited by its hardware performance or loss during a photographing process is solved, thereby achieving the effect of improving terminal imaging.
