Patent ID: 8116008

Claim:
A method for cost and performance optimization in a lens assembly, having a plurality of lens elements, said method comprising: designing a lens assembly, wherein cost and performance optimization is achieved by simplifying the lens assembly by relaxing constraints designed for optically correcting lateral chromatic aberration (LCA) and distortion; obtaining input image data, having a number of color components, through a plurality of geometry correction units, such that each of said plurality of geometry correction units corresponds to one color component of the number of color components; electronically warping the input image data, using the geometry correction units, that utilize surface functions to represent grid transformation data mapping, independently for each color component of the number of color components to pre-compensate for the LCA and the distortion, and form an output image data which is pre-compensated for the LCA and the distortion; and projecting the output image data onto the lens assembly for further optical processing.
