Abstract
A lens shading correction circuit includes an elliptical gain generation circuit configured to extract a position of a pixel and generate an elliptical gain value using elliptical gain parameters and the extracted position and a multiplier configured to output an output value by multiplying the elliptical gain value by a weight for the pixel. The lens shading correction circuit corrects the lens shading based on the first output value and a gain increment value.
