[0003] An appropriate amount of highlights can reflect the unevenness of the object being photographed, so that the captured image has a three-dimensional effect, but if the highlights cover the original shape, color, texture and other characteristics of the object, it will affect the recognition and image quality of the object being photographed in the image. affect the shooting effect of
For example, if there is a high-light area in the captured face image, it will cause the face to look unnatural and seriously affect the visual effect of the image.

The invention discloses a processing method and device for a highlight area in an image and terminal equipment. The method comprises the steps that a to-be-processed image is preprocessed, and the highlight area and a non-highlight area contained in the to-be-processed image are determined; and correction processing is performed on a second three-primary-color value corresponding to the highlight area according to a first three-primary-color value corresponding to the non-highlight area. In this way, correction processing on the highlight area in the to-be-processed image is realized, the influence of the highlight area on the image is lowered, the visual effect of the image is improved, and the quality of the image is improved.
Description
technical field [0001] The present invention relates to the technical field of image processing, in particular to an image highlight area processing method, device and terminal equipment. Background technique [0002] Usually, when a user takes a photo under a certain lighting condition, due to the difference in the surface material of the object or the uneven lighting, a local highlight area often appears in the captured image. [0003] An appropriate amount of highlights can reflect the unevenness of the object being photographed, so that the captured image has a three-dimensional effect, but if the highlights cover the original shape, color, texture and other characteristics of the object, it will affect the recognition and image quality of the object being photographed in the image. affect the shooting effect. For example, if there is a highlight area in the captured face image, the face will look unnatural, which seriously affects the visual effect of the image. [00...
