Abstract

The embodiment of the invention discloses a multi-camera brightness synchronization method. The method comprises the following steps: determining a statistical information area, wherein the statistical information area is located in an image acquired by the multi-camera module; uniformly dividing the statistical information area into a plurality of statistical blocks according to the size of the statistical information area; obtaining a brightness value of each statistical block; and acquiring a brightness synchronization parameter according to the acquired brightness value of each statisticalblock. According to the invention, the efficiency and accuracy of brightness synchronization of the multi-camera module can be improved.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to a multi-camera brightness synchronization method, equipment, device and storage medium. Background technique [0002] With the popularity of smart devices, the shooting mode of smart devices has developed from a single-camera form to a multi-camera module form. A multi-camera module is composed of multiple cameras that cooperate with each other, and the imaging brightness of each camera is required to be consistent. Currently, in the single-shot mode, the smart device uses an automatic exposure algorithm to adjust the brightness of the captured image to make the captured image suitable for human eyes. In the multi-camera mode, the brightness of each camera is affected by the environment and cannot be consistent. If the brightness of each camera cannot be balanced, the shooting effect will be reduced and the user experience will be affected. Contents of the invention ...
