Embodiment Construction
[0068] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0069] see Figure 1a , Figure 1a Shown is a schematic diagram of an image with a grid pattern. The areas that should be connected in the image are divided into multiple grids by the grid pattern, which affects the visual effect of the image. In view of this, the embodiment of the present invention provides a method for weakening grid pattern of an image, which can be referred to figure 2 ,include:

The embodiment of the invention provides an image grid line weakening method and device and electronic equipment. The method comprises the steps that a plurality of pixel blocks are determined in a to-be-processed image, and pixel points in each pixel block belong to the same grid; edge detection is carried out according to the edge relation between the pixel blocks, and texture edges are determined; and sharpening processing is performed on the pixel points at the texture edge to obtain the to-be-processed image after the grid lines are weakened. According to the technical scheme, the image with the grid lines can be processed by taking the pixel blocks divided according to the grids as units, and the grid lines in the image are effectively weakened and the visual effect of the image is improved by fully utilizing the forming mechanism of the grid lines and the distribution characteristics of the pixels in the image caused by the grid lines.
Description
technical field [0001] The invention relates to the technical field of image processing, in particular to an image grid pattern weakening method, device and electronic equipment. Background technique [0002] In some application scenarios, limited by the acquisition conditions of optical signals, it may be possible to use an objective lens group composed of multiple objective lenses to jointly collect optical signals, and recombine the collected optical signals into a focused image at the imaging end. For example, a fiber endoscope uses a fiber optic array composed of multiple fiber optic surfaces to collect optical signals, and uses multiple light guide fibers to transmit the optical signals collected by each fiber optic surface to the imaging end. The end recombines these optical signals into a focused image. [0003] However, it may be difficult for the objective lenses in the objective lens group to completely cover all the image planes, and the optical signals emitted ...
