Abstract

The invention provides an exposure control method and device and electronic equipment. The method comprises the steps that according to overexposure areas and non-overexposure areas in a preview image, a light ratio of the preview image is determined, according to the light ratio, a preset initial exposure quantity EV level combination is adjusted to obtain a target EV level combination, and according to the target EV level combination, exposure control is conducted. On the basis of the light ratio of the preview image, the preset exposure quantity level combination is adjusted, and the exposure quantity level combination is adjusted dynamically according to different night scene brightness, so that under modes of night scenes with different brightness, high imaging quantity can be obtained separately; the technical problems that in the prior art, a fixed EV level combination is adopted, and the imaging requirements with different night scene brightness cannot be met, so that the imaging quality is low are solved.

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] For this reason, the present invention proposes an exposure control method, which adjusts the preset expo...
