ABSTRACT:
Methods and apparatuses for vignetting correction of imager pixels signals. A polynomial correction surface is determined based on a pixel array center, height, and width, surface fitting parameters, and pixel coordinates. The pixel signal is then multiplied by the corresponding value from the polynomial correction surface to create a vignetting corrected signal.
