Abstract:
Techniques for correcting image data in a lens shading correction circuit include accessing numerical constants associated with channels of a captured image represented by a pixel array from a memory. The techniques further include calculating lens shading correction factors for the captured image for each pixel of a channel in the pixel array according to the x-y pixel position of the pixel based on a lens shading correction formula and the numerical constants. For the channel in the pixel array, the correction formula applies different subsets of the numerical constants to different radial portions of the pixel array. The techniques also includes performing lens shading correction for the captured image based on the calculated lens shading correction factors to produce corrected image data, and storing the corrected image data in a non-transitory computer-readable medium.

Claim (Index 7):
The method of  claim 1 ,\n wherein the channel of the pixel array is one of a plurality of channels of the pixel array, the method further comprising calculating lens shading correction factors for each pixel in the pixel array based on different subsets of the numerical constants for at least three of the plurality of channels of the pixel array.
