Abstract

The invention provides a double-camera color synchronization method and device, and a terminal. The method comprises the steps that the double cameras obtain Bayer images; the white balance gain parameters of the Bayer images are calculated, and current environment light source color temperature is obtained; a color synchronization coefficient is obtained by employing the calculated color temperature according to a color synchronization coefficient mapping table; a digital signal processor applies the color synchronization coefficient to a next Bayer image photographed by a non-reference camera. According to the method, the device and the terminal, the image data is based on the Bayer image data; compared with 8-bit images processed by an image signal processor ISP, 10-bit Bayer images have richer data information, and therefore, the effect of an image synthesized by employing the Bayer images is better. According to the method, the device and the terminal, the original data color consistency of the double cameras is calibrated, the vision difference resulting from color inconsistency is improved, the synthesizing effect of the double cameras is improved, and the user experience is improved.

Description

technical field [0001] Embodiments of the present invention relate to camera color synchronization, and in particular to a dual camera color synchronization method, device and terminal. Background technique [0002] At present, binocular synthesis of images output by binocular cameras to improve image quality has been successfully applied in mobile terminals. The image synthesis of the image processed by the camera through the image signal processing chip (ISP) can achieve a relatively stable effect. However, in order to achieve a better synthesis effect, image synthesis is performed on raw data (RAW) domain image data generated by the image sensor and transmitted from the image sensor to obtain a better imaging effect. If the RAW image data that has not been processed by the basic ISP of the terminal platform is directly synthesized, there will be a visual difference between the overlapping area of ​​the synthesized image and the non-overlapping area, and even cause the sy...
