1. A method for generating a virtual view of a scene associated with a vehicle, the method comprising:
obtaining image data including a plurality of images of the scene captured by a plurality of cameras of the vehicle;
obtaining steering angle data captured by a sensor of the vehicle;
detecting, by a processor, a shadow in at least one image of the plurality of images based on solar position data;
determining, by the processor, auto-white balance data for each image of the plurality of images;
selectively combining, by the processor, the auto-white balance data of the images based on the detected shadow, and the steering angle data, wherein the selectively combining comprises:
prioritizing the images based on the detected shadow and the steering angle; and
assigning a weight to each image based on the priority; and computing a weighted average of the auto-white balance data based on the assigned weights; and
generating, by the processor, output image data to provide the virtual view of the scene on a display of the vehicle based on the combined auto-white balance data and the image data.
