Abstract:
A lens shading correction circuit includes a gain generator configured to generate a first gain value for each pixel of an input image in response to a gain generation parameter, and an adjustment circuit configured to receive the first gain value and first YUV data, and to adjust at least one of U and V values of the first YUV data using at least one of the first gain value and a Y value of the first YUV data.
