Abstract: Aspects of the present disclosure are directed to a process for applying, in a distributed manner, Auto White Balance (AWB) correction techniques to images acquired at an imaging device. AWB is used to adjust the color balance of an image to make the image look more natural and appealing to the viewer. AWB can neutralize color casts that may be present in an image, such as those caused by the lighting conditions or the camera's sensors. The absence of AWB correction can cause an image to have incorrect colors, such as a green tint, while a failure in AWB can often be perceived as the image having an incorrect color tint. In examples, at least a portion of the computational complexity involved in performing AWB correction techniques can be offloaded to a companion computation device, such as a coprocessing device.
