Abstract

The invention provides a double-camera white balance synchronization method, a double-camera white balance synchronization device and a terminal. The double-camera white balance synchronization method comprises the steps of acquiring one Bayer image by each of the double cameras; respectively calculating the white balance gain of respective color channel of each of the double cameras; and applying the calculated white balance gain on a next image frame for realizing white balance synchronization. The image data in the double-camera white balance synchronization method are based on the Bayer image data. Compared with a 8bit image which is processed by an image signal processing chip (ISP), a 10bit Bayer image has an advantage of more abundant data information, and therefore higher image effect in Bayer image synthesis is realized. The double-camera white balance synchronization method, the double-camera white balance synchronization device and the terminal have advantages of improving double-camera image data synthesis effect, realizing better imaging effect and improving user experience.

Description

technical field [0001] Embodiments of the present invention relate to camera white balance synchronization, and in particular to a dual camera white balance synchronization method, device and terminal. Background technique [0002] In modern life, the camera is one of the main tools to record people's activities and memories. However, the photos taken by commonly used cameras often have distortion or discoloration. White balance is one of the key factors. Patent No. CN201510970897 proposes an automatic white balance synchronization method for multi-camera units, which synchronizes the white balance differences of multiple cameras after processing by an image signal processing chip (ISP). The method uses the white balance result obtained by each camera unit as the first confidence level, and then obtains the public white balance result according to the calibration data. [0003] In the field of mobile terminals, the synthesis of dual-camera raw data (RAW) domain image data...
