Abstract
System and methods are provided for performing color lens shading correction. A plurality of mesh points are generated. Mesh gain parameters associated with the mesh points are determined. The mesh gain parameters are applied to an input image for color lens shading correction. A color entropy related to color distribution of the corrected input image is obtained. The mesh gain parameters are adjusted to reduce the color entropy.
