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

The invention relates to an image adjusting method and device, a chip, a display device and an electronic device. The adjusting method comprises the steps of obtaining 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 a plurality of preset gray scales in each to-be-processed sub-image, determining a dynamic contrast corresponding to each preset gray scale; determining a statistical feature corresponding to each to-be-processed sub-image and a gray scale space distribution feature corresponding to each to-be-processed sub-image; according to the statistical characteristic corresponding to each to-be-processed sub-image, the gray scale space distribution characteristic corresponding to each to-be-processed sub-image and the dynamic contrast ratio corresponding to each preset gray scale in each to-be-processed sub-image, calculating the corresponding to-be-processed sub-image according to the statistical characteristic corres
