Abstract

The invention discloses an image noise reduction processing method, a mobile terminal, a device and a computer storage medium, and the method comprises the steps: obtaining a display image to be subjected to noise reduction processing, and carrying out the block processing of the display image based on a preset first block size, so as to obtain each first image block after the block processing; traversing each first image block in sequence, and judging whether a second image block exists in each first image block one by one; wherein the second image block is a first image block of which the regional light and shade degree is not matched with the size of the first block; and if the second image block exists in each first image block, updating the size of the first block, and performing block processing on the second image block again according to the updated size of the first block until the traversal of each first image block is completed, and performing noise reduction processing on each first image block after traversal is completed. The technical problem that in the prior art is solved. After image noise reduction processing is conducted on an image, images are not prone to distortion.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image noise reduction processing method, a mobile terminal, a device, and a computer storage medium. Background technique [0002] In the process of image noise reduction processing performed by the mobile terminal, in order to obtain a good image noise reduction processing effect, the image is usually divided into blocks to obtain each image block, and then each image block is processed. In different light scenes, the size of image blocks suitable for image noise reduction processing is different. In dark scenes, too small blocks will cause the processed image to be blurred, and in bright light scenes, too large blocks will lead to noise reduction. The effect is not good. For example, for photos taken in bright light scenes, it is more appropriate to divide them into blocks with a size of 32*32, but for photos taken in dark light scenes, it is more appropriat...
