Embodiment Construction

[0094] 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.

[0095] In the related art, some captured images are distorted, mostly because the shooting lens is circular while the image is rectangular. Distortion causes image distortion and affects image quality. Therefore, the image can be distorted to solve this problem. However, there may be watermarks in the image, such as watermarks indicating when and where the image was taken, etc. The ...

Abstract

The invention relates to an image processing method and a device, wherein the distortion of a watermark in an image is reduced during the image processing operation and the image quality is therefore improved. The method comprises the following steps of for each pixel point in a to-be-processed distortion image, acquiring one pixel point of the to-be-processed distortion image; judging whether the coordinate of the pixel point belongs to a known watermark area or not; when the coordinate of the pixel point belongs to the preset watermark area, keeping the coordinate of the pixel point to be unchanged; when the coordinate of the pixel point does not belong to the preset watermark area, subjecting the pixel point to distortion treatment.

Description

technical field [0001] The present disclosure relates to the fields of communication and computer processing, and in particular to a method and device for image processing. Background technique [0002] With the development of electronic technology, devices such as mobile terminals and digital cameras have been widely used. People have higher and higher requirements for photography quality. In order to meet the needs of users, photography equipment such as mobile terminals and digital cameras can be equipped with lenses with higher shooting performance such as wide-angle lenses. However, the picture taken by the wide-angle lens has distortion at the edge, which affects the picture quality. Images can be distorted to improve image quality. However, if the image contains a watermark, the watermark will be deformed during distortion processing, which will affect the image quality instead. Contents of the invention [0003] In order to overcome the problems existing in rela...
