Abstract
An apparatus includes a plurality of camera units where each camera unit has a lens, a sensor that can detect at least three colors, and camera unit calibration data for each camera unit is stored in non-volatile, non-transitory memory. The apparatus also includes multi-camera auto white balance synchronization logic that is operatively coupled to each camera unit. The multi-camera auto white balance synchronization logic is operative to determine common white balance results based on the camera unit white balance results per frame and the camera calibration data. The common white balance results are provided to image signal processing pipelines such that a merged frame can be obtained by combining the frames of each camera after performing white balance and color correction using the common white balance results.
