Problems solved by technology

In the prior art, when adjusting the brightness of an image, the brightness of the entire image is reduced or increased. When the brightness of the entire image is reduced, it is easy to darken the part with lower brightness in the image, resulting in this part The image quality is poor; when increasing the brightness of the entire image, it is easy to brighten the part with higher brightness in the image, resulting in poor image quality in this part
That is to say, at present, when reducing the brightness of the entire image or increasing the brightness of the entire image, the image quality of the local image area will be reduced, resulting in poor quality of the entire image

Abstract

The embodiment of the invention provides an image brightness adjusting method and device, electronic equipment and a medium. The method comprises the following steps: acquiring a to-be-adjusted first image; dividing the first image into a plurality of image parts; for a first image part in the plurality of image parts, determining a brightness adjustment strategy according to the brightness of the first image part, and performing brightness adjustment on the first image part according to the brightness adjustment strategy to obtain a second image part; and replacing the first image part with the second image part in the first image to obtain a second image. According to the embodiment of the invention, the brightness of the first image part is adjusted according to the brightness of the first image part in the image, the image quality of the first image part is improved, and the image quality of other image parts except the first image part in the image is ensured to be unchanged, so that the quality of the whole image is ensured, and the user experience is improved.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular, the present disclosure relates to a method, apparatus, electronic device and medium for adjusting the brightness of an image. Background technique [0002] With the continuous development of computer technology, more and more electronic devices have the function of acquiring images. Users can use electronic devices with shooting functions to take pictures anytime and anywhere to obtain the images the users want. Users can also obtain images from the Internet. Get the image the user wants. [0003] Usually, since the brightness distribution of the image is uneven, the brightness of some image areas is high, and the brightness of some image areas is low, and the user needs to adjust the image brightness of the acquired image. In the prior art, when the brightness of an image is adjusted, the brightness of the entire image is reduced or the brightness of the ent...
