Abstract
Systems, methods, and devices for applying lens shading correction to image data captured by an image sensor are provided. In one embodiment, multiple lens shading adaptation functions, each modeled based on the response of a color channel to a reference illuminant, are provided. An image frame from the image data may be analyzed to select a lens shading adaptation function corresponding to a reference illuminant that most closely matches a current illuminant. The selected lens shading function may then be used to adjust a set of lens shading parameters.
