Problems solved by technology

[0003] In some special scenes, such as in low-light scenes, the amount of light entering is small when shooting, which is greatly affected by noise, and the image quality is low. For example, in backlit scenes, the captured object is darker than the surrounding environment. Highly affected by noise
At present, although some user terminals have both image processing functions and are better at processing images taken in normal environments, for special scenarios like the ones listed above, if the image processing method in normal environments is still used The captured image is processed, which may cause serious blurring of the processed image

Abstract

An image processing method and a user terminal, wherein the image processing method includes: when receiving an activation command for the camera of the user terminal, displaying a preview image in the shooting area of ​​the camera; if the preview image contains a human face element, obtaining The environmental parameters of the preview image, the environmental parameters include: sensitivity ISO value and / or brightness contrast value; set image processing coefficients for the preview image according to the environmental parameters; use the image processing coefficients to process the preview The image is processed. The technical solutions of the embodiments of the present invention are beneficial to improving the flexibility of image processing.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method and a user terminal. Background technique [0002] With the popularization and development of user terminals with cameras, such as mobile phones and tablet computers, taking pictures has gradually become an important way to record travel, life and other aspects. People can take pictures through user terminals, and send them to personal platforms such as Weibo and WeChat through the network to share with friends and family. In order to make the visual effect of the captured image better, the user can set corresponding parameters through the graphics processing software to process the currently captured image. [0003] In some special scenes, such as in low-light scenes, the amount of light entering is small when shooting, which is greatly affected by noise, and the image quality is low. For example, in backlit scenes, the captured objec...
