Abstract

The invention provides a method and a device for synchronizing multiple cameras. By obtaining the white balance gain of a main camera to obtain the color temperature of the ambient light source, Then,the white balance gain and color correction matrix of each sub-camera are calculated by using the color temperature of the environmental light source, so that the color temperature of the environmental light source of the main camera and each sub-camera is always consistent, the white balance synchronization and the color synchronization are carried out, the visual difference caused by the colorinconsistency is improved, and the composite effect of the images is improved.

Description

technical field [0001] The present invention relates to the technical field of camera synchronization, in particular to a multi-camera synchronization method and device. Background technique [0002] In modern life, the camera is one of the main tools for recording people's activities and memories. In order to improve the image quality, binocular camera output images can be used for binocular synthesis, and it has been successfully applied in mobile terminals. With the popularization of the binocular camera system, in the binocular camera system, how to synchronize the white balance gain and color of each camera has become an urgent problem to be solved. In the existing binocular camera system, the synchronization method of the binocular camera Usually: the binocular cameras calculate their respective white balance gains to achieve white balance synchronization, and then calculate the current ambient light source color temperature respectively, and use the calculated ambient...
