Abstract

The invention discloses an exposure method and device. The method comprises that the light intensity within a first viewing scope of a first camera is detected to obtain first light information, the light intensity within a second viewing scope of a second camera is detected to obtain second light information, and first and second exposure values are determined according to the first and second exposure information respectively; and the first and second cameras are controlled to collect images of a shooting object according to the first and second exposure values respectively.

Description

technical field [0001] The invention relates to electronic technology, in particular to an exposure method and device. Background technique [0002] At present, when a mobile terminal uses dual cameras to capture images or find a view, controlling the cameras to perform reasonable exposure according to appropriate exposure compensation is a crucial condition for obtaining high-quality images. Most of the current terminals support manual exposure adjustment. Manual exposure adjustment can be done in the following ways: the user triggers the mobile terminal to display the exposure bar on the screen by clicking the setting button, and the user slides the cursor in the exposure bar to adjust the exposure when the image is taken. Exposure compensation is set to achieve the purpose of adjusting the exposure effect. [0003] At present, when a mobile terminal performs exposure processing on an image, it performs the same exposure compensation processing on the images of the two ca...
