Abstract

The embodiment of the invention relates to the field of electronic technology, and discloses an image processing method and a mobile terminal. The method comprises steps: when a brightness value of the current environment is detected to be smaller than a preset brightness threshold, the mobile terminal increases current sensitivity of a camera to target sensitivity, the camera is controlled to use the target sensitivity to carry out image acquisition on a shooting object in a preset shooting view angle, a first image is obtained, saturation of the first image is reduced, a second image is thus obtained, and the second image is outputted on an image preview interface. Through the embodiment of the invention, the mobile terminal automatically increases the sensitivity of the camera in a dark environment, when the increased sensitivity is used for acquiring the image, brightness of color noise points in the image is reduced through reducing the saturation of the image, the color noise points can be effectively reduced, the image is more distinct, and visibility of the image is enhanced.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to an image processing method and a mobile terminal. Background technique [0002] Present mobile terminals such as smart phones, tablet computers, etc. are all equipped with cameras, and users can take pictures or video through the cameras. After the camera captures the image, it will display and process the captured image according to a specific saturation, and then display it in the image preview interface. Usually, if the user uses the camera to shoot in a dark environment, due to the weak light in the shooting environment, the brightness of the image collected by the camera is low, and the visual performance is blurred. In the prior art, in order to increase the brightness of an image collected in a dark environment, the mobile terminal generally automatically increases the sensitivity ISO of the camera. However, as the light sensitivity of the camera increases, t...
