Example Embodiment

[0023] The application will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described here are only used to explain the application, but not to limit the application. In addition, it should be noted that, for ease of description, the drawings only show a part of the structure related to the present application instead of all of the structure.

[0024] Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowchart describes the steps as sequential processing, many of the steps can be implemented in parallel, concurrently, or simultaneously. In addition, the order of the steps can be rearranged. The processing may be terminated when its operation is completed, but may also have additional steps not included in the drawings. The processing may correspond to m...

Abstract

The embodiments of the invention disclose portrait face adjustment methods and device, a memory medium and a terminal. A method comprises the steps of determining a face reflection excessive area in atarget image based on a brightness distribution state; determining a reference adjustment area adjacent to the face reflection excessive area according to a geometrical shape of the face reflection excessive area; and adjusting an image attribute of each pixel in the face reflection excessive area based on an image attribute mapping relationship between the reference adjustment area and the facereflection excessive area. Through adoption of the technical scheme, image attribute information such as brightness and saturability is extracted from the adjacent reference adjustment area of the face reflection excessive area and the image attributes of the pixels in the face reflection excessive area are adjusted, so the face reflection excessive problems resulting from face shine or glasses reflection are effectively improved, and image definition is improved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of terminals, and in particular, to a portrait face adjustment method, device, storage medium, and terminal. Background technique [0002] With the rapid development of terminal technology, electronic devices such as mobile phones and tablet computers have image acquisition functions, and users have higher and higher requirements for the quality of images collected by terminals. [0003] At present, when shooting a portrait, the face area is easily affected by external ambient light, so that some areas of the face appear overly bright, resulting in a poor photo effect. In response to this problem, related technologies provide a solution to eliminate excessively reflective areas by using the average brightness value of the face area. This method may lead to an obvious deviation in the brightness of the adjusted excessively reflective area and the adjacent area, so that the face pr...
