Abstract

The present invention proposes an exposure control method, device, and electronic equipment, wherein the method includes: performing photometry on preset points in the preview image to obtain the scene brightness, and performing a combination of preset initial exposure EV levels according to the scene brightness Adjust to obtain the target EV level combination, perform exposure control according to the target EV level combination, adjust the preset exposure level combination based on the detected scene brightness of the current environment, and realize the dynamic adjustment of the exposure level according to different night scene brightness The combination enables higher imaging quality to be obtained under different brightness night scene modes, and solves the technical problem in related technologies that using a fixed EV level combination cannot meet the imaging requirements of different night scene brightness, resulting in lower image quality.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to an exposure control method, device and electronic equipment. Background technique [0002] With the continuous advancement of mobile terminal technology, users have higher and higher requirements for the effect of mobile terminal photography, especially for night scenes. Even in night scenes with large changes in light and dark distribution, it is necessary to obtain Clear imaging. [0003] At present, in the night scene shooting mode, a fixed exposure value (EV) setting is used for image acquisition, and this method cannot be applied to all night scene environments, resulting in poor image quality. Contents of the invention [0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. [0005] To this end, the present invention proposes an exposure control method, which adjusts the preset exposure...
