Abstract

The invention provides an image processing method and device, a terminal and a readable storage medium. The image processing method comprises the following steps: step 1, acquiring an initial image which comprises a plurality of blocks with the same size, wherein each block comprises at least one pixel point; step 2, using any one of the blocks as a target block, obtaining weight values of a plurality of adjacent blocks around the target block according to gain data corresponding to the target block in the expansion graph and a noise level of the target block, the adjacent blocks being blocks surrounding and connected to the target block, wherein the size of the expansion image is the same as that of the initial image; and step 3, performing noise reduction processing on the target block according to the plurality of weight values, and traversing all blocks in the initial image, taking each block as a primary target block, and repeatedly executing the second step and the third step to obtain a noise reduction image.

Description

technical field [0001] The present application relates to the field of electronic technology, and more specifically, to an image processing method, an image processing device, a terminal, and a non-volatile computer-readable storage medium. Background technique [0002] In the image signal processing (Image Signal Process, ISP) system, because the light gathering ability of the central area of ​​the convex lens is much greater than that of its edge area, the light in the central area of ​​the sensor is stronger than that of the edge area, so in the ISP system, there is a lens shadow The Lens Shading Correction (LSC) module is used to increase the brightness of the corners of the image, so that the brightness of the whole image is nearly consistent. However, after the corner area is brightened by the LSC module, the noise will be more obvious. [0003] The current optimization method for corner noise is to adjust the pixel noise reduction intensity by calculating the distanc...
