Embodiment Construction

[0100] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0101] In the related art, in the process of actually taking pictures, distortion will occur at a position farther from the center of the camera, especially when the distortion occurs at the position of a human face, it is easier to be perceived. However, the method of distortion correction in the related art usually corrects the whole image, and this method will change the background,...

Abstract

The present disclosure relates to an image correction method and device, and a storage medium; the method includes: determining the correction offset of each correction unit in the image; determining at least one target area in the image; determining the target area according to the target area The image weight coefficient of each correction unit in the image; according to the image weight coefficient and the correction offset, determine the final offset of each correction unit in the image; according to the final offset to the image Each correction unit in the correction is carried out. Through the technical solution of the present disclosure, by setting image weight coefficients, different regions of the image can be corrected to different degrees according to requirements.

Description

technical field [0001] The present disclosure relates to image processing technologies, and in particular to an image correction method and device, and a storage medium. Background technique [0002] In the related art, since the lens of the camera is composed of optical lenses, when the camera is used to take pictures, distortion or image deformation is likely to occur, which is called image distortion. Image distortion includes pincushion distortion, barrel distortion, and linear distortion. It is impossible to completely eliminate image distortion, and it is also difficult to avoid it during the shooting process. The only way to correct the image distortion is to process the photos that have been taken to reduce the impact of distortion as much as possible. The existing image distortion correction methods are relatively simple, usually the whole image correction, without considering the particularity of the target area in the image. [0003] For example, when taking a p...
