Abstract

The embodiment of the invention provides a photographing method and device, a storage medium and a terminal. The method comprises: when an ambient brightness value is less than a preset threshold, a light sensitivity value of a camera is determined according to the ambient brightness value; a plurality of frames of images shot by the camera on the light sensitivity condition are obtained; at least two frames of images are selected from the plurality of frames of images to carry out synthesis, thereby obtaining a first image; and according to a preset adjusting parameter, the brightness of the first image is adjusted, so that a second image is obtained. According to the invention, when the terminal is in a dark environment, the light sensitivity value is determined based on the ambient brightness value, so that noisy points in a image can be reduced wile image shooting is carried out; after the synthesis of the shot images, the brightness of the first image is adjusted to enhance the brightness of the first image, so that the image brightness can be guaranteed and the noisy points in the image can be reduced and thus the image quality can be improved.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular to a photographing method, device, storage medium and terminal. Background technique [0002] Currently, the photographing function of mobile terminals such as smart phones is becoming more and more perfect. The mobile terminal can be carried around, and the mobile terminal can be used to take pictures anytime and anywhere, thereby bringing great convenience to the life of the user. [0003] However, when using a mobile terminal to take pictures, in some scenes with relatively low brightness, it is necessary to use a higher sensitivity to take pictures to meet the exposure requirements during shooting. However, taking a photo with a higher sensitivity will result in a lot of noise (unexpected pixels in the photo) in the photo. The presence of these noises seriously affects the quality of the photo.
