Problems solved by technology

When the mobile terminal performs image processing, it directly performs image enhancement on the scene in the entire image. Using this method, the target area in the image can be enhanced, but the background area in the image is clearly bright and dark under this shooting condition. Therefore, using this method The enhancement algorithm will overexpose the background area and cannot improve the shooting effect

Abstract

The invention discloses an image enhancement method. The method comprises steps: the mobile terminal acquires multiple images via a multi-view vision platform, and according to the multiple images, a depth image and position information of an object in a shooting scene is acquired; according to the position information and the depth image pixel information, image segmentation processing is carried out on the depth image to acquire a target area; and local enhancement processing is carried out on the target area. The invention also discloses a mobile terminal for the image enhancement. Accurate segmentation is carried out on the target area in the image acquired by the multi-view vision platform according to the position information of the object in the shooting scene, the target area is then subjected to local enhancement, and image shooting effects in a backlighting environment can be improved.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to an image enhancement method and a mobile terminal. Background technique [0002] In the process of capturing images by mobile terminals and performing 2D plane processing on the images, if the images captured by the mobile terminals encounter a backlight environment, the target area in the image will become dark due to the backlight, making the background of the entire screen too bright. Highlighted, the light and dark effects of the target area are suppressed. When the mobile terminal performs image processing, it directly performs image enhancement on the scene in the entire image. Using this method, the target area in the image can be enhanced, but the background area in the image is clearly bright and dark under this shooting condition. Therefore, using this method The enhancement algorithm will overexpose the background area and fail to improve the shot. ...
