Abstract:
Systems and methods to improve the white balance of a high dynamic range image are disclosed. In a particular embodiment, an imaging device includes a camera sensor and a processor, the processor configured to capture a lighter image and a darker image of a scene. The processor is then configured to white balance the lighter image based on the lighter regions of the image, and to white balance the darker image based on the darker regions of the image. The two images can then be combined to produce a final image.
