Image adjusting method and device, chip, display equipment and electronic equipment

The invention relates to an image adjusting method and device, a chip, display equipment and electronic equipment. The adjusting method comprises the following steps: acquiring a to-be-processed image; dividing the to-be-processed image into a plurality of to-be-processed sub-images; for each preset gray scale in the plurality of preset gray scales in each to-be-processed sub-image, determining a dynamic contrast ratio; determining statistical characteristics corresponding to each to-be-processed sub-image, and determining a first brightness value of each preset gray scale according to the statistical characteristics and the dynamic contrast; determining a gray scale space distribution feature corresponding to each to-be-processed sub-image, and determining a second brightness value of each preset gray scale according to the gray scale space distribution feature and the first brightness value corresponding to each preset gray scale in each to-be-processed sub-image; and determining a brightness value correspo
