Abstract

The present invention discloses an image processing method and apparatus. According to one embodiment of the present invention, the method includes the following steps that: whether an image to be processed requires pseudo color correction processing is determined; if it is determined that the image to be processed requires the pseudo color correction processing, the characteristics of each pixel in the image to be processed are determined according to the color component values of each pixel in the image to be processed, and pixels to be subjected to pseudo-color correction and pixels which do not require pseudo-color correction are determined according to the characteristics of each pixel in the image to be processed; and the pixels to be subjected to pseudo-color correction are corrected according to the characteristics of the pixels to be subjected to pseudo-color correction, so that a corrected image of the image to be processed can be obtained. According to the image processing method and apparatus provided by the embodiments of the invention, the pixels to be subjected to the pseudo-color processing are corrected, a pseudo-color phenomenon can be eliminated or alleviated under the premise that the definition and color of the image are not affected, and the subjective feelings of the eyes of people can be improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method and device. Background technique [0002] The image captured by the camera often has "purple fringing". "Purple fringing" is a relatively common "false color" phenomenon, and sometimes it also appears in other colors such as "red" and "blue". It is also more sensitive than other colors, so "purple fringe" is used to refer to this kind of "false color" phenomenon. [0003] There are many causes of "purple fringing". A typical camera system is composed of lens, photoelectric sensor, post-processing chip, etc. Every part of the camera system may cause "purple fringing". Aspects of causes: [0004] 1. Light source: There is a certain amount of ultraviolet rays in natural light, especially in cloudy and strong sunshine weather, there will be a lot of ultraviolet rays and stray light in the air. As a common light source, fluorescent lamps ...
