Method for adjusting image noise, storage medium and electronic device

The embodiment of the invention provides a method for adjusting image noise, a storage medium and an electronic device, and the method comprises the steps: obtaining a target brightness value of each region of a target image, the target image is divided into a plurality of regions, each region comprises at least one pixel point, and the target image is an image obtained through carrying out the brightness adjustment of an original image; obtaining the noise size of each region obtained by performing i-th noise adjustment on the target image, i being an integer greater than or equal to 0; according to the target brightness value and the noise magnitude, determining an adjustment state parameter of each region, the adjustment state parameter being used for indicating whether each region needs the (i + 1) th noise adjustment; and under the condition that the adjustment state parameter of the target area indicates that the target area needs to be subjected to the (i + 1) th noise adjustment, the noise size of the
