Problems solved by technology

[0002] At present, in the case of uneven lighting, the facial area of ​​the person in the captured image is prone to blocky highlight areas, which makes the captured image unnatural and affects the aesthetics and naturalness of the image.
[0003] In the related technology, the beauty algorithm is used to reduce the size and degree of the highlight area, and directly perform high-intensity filtering to smooth the image, resulting in serious loss of relevant details in the image, resulting in a very unnatural processing result for the highlight area.

Embodiment Construction

[0028] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0029] The following describes the image processing method, device, and terminal device according to the embodiments of the present invention with reference to the accompanying drawings.

[0030] Based on the above analysis, it can be seen that in the prior art, the highlight area of ​​the image is processed in a relatively "simple and rough" way, and the highlight is extracted by directly performing high-intensity filtering on the image, resulting in serious loss of relevant details in the image. For example, for For portrait im...

Abstract

The invention proposes an image processing method and device and terminal equipment. The method includes obtaining an area of interest from an image; extracting a highlight subarea from the area of interest; obtaining the mean value of R, G and B channels in a first subarea in the area of interest and the mean value of R, G and B channels in the highlight subarea; wherein the first subarea is an area in the area of interest except the highlight subarea; adjusting the area of interest according to the two mean values of R, G and B channels to obtain the adjusted area of interest; fusing the area of interest and the adjusted area of interest to obtain a target area of interest; and utilizing the target area of interest to replace the area of interest in the original image to obtain a target image. Thus, on the premise of keeping details in the original image, the highlight area in the image is effectively removed, so that a processed image is more natural.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method, device and terminal equipment. Background technique [0002] At present, in the case of uneven illumination, blocky highlight areas tend to appear in the face area of ​​the person in the captured image, which makes the captured image unnatural and affects the aesthetics and naturalness of the image. [0003] In the related technology, the beauty algorithm is used to reduce the size and degree of the highlight area, and directly perform high-intensity filtering to smooth the image, resulting in serious loss of relevant details in the image, resulting in a very unnatural processing result for the highlight area. Contents of the invention [0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. [0005] Therefore, the first object of the present invention is to propose ...
