Problems solved by technology

For images with both brighter and darker images (such as waterfalls or lights), if the exposure time is not used or the exposure time is too short to shoot, the photos taken in the darker images will be unclear due to underexposure. If you use long exposure to shoot, it will make the photo taken in the brighter picture appear overexposed due to the long exposure time, reducing the picture quality

Abstract

The invention discloses an image processing method. The method comprises: obtaining a first exposure time set by a user; determining a second exposure time, wherein the second exposure time is less than the first exposure time, and the first exposure time is a moment when a photographing target begin to occur an overexposure phenomenon; obtaining N pictures of the photographing target within the second exposure time, wherein N is an integer greater than 1; and carrying out gain compensation processing on the N pictures, and integrating the N pictures after the gain compensation processing to obtain a target picture. The embodiments of the invention further provide a mobile terminal. By adopting the image processing method disclosed by the embodiments of the invention, picture fuzziness caused by insufficient exposure and the overexposure phenomenon caused by too long exposure can be avoided to improve the picture quality.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method and a mobile terminal. Background technique [0002] The long exposure can be achieved by using a shooting device (such as a mobile terminal or a camera with a shooting function), which can satisfy long exposure shooting in a dark environment. For images with both brighter and darker images (such as waterfalls or lights), if the exposure time is not used or the exposure time is too short to shoot, the photos taken in the darker images will be unclear due to underexposure. If you use long exposure to shoot, it will make the captured photo overexposed due to the long exposure time in the brighter picture, which will reduce the picture quality. Contents of the invention [0003] Embodiments of the present invention provide an image processing method and a mobile terminal, which are used to avoid unclear picture quality due to underexpos...
