Abstract: Methods of correcting saturated pixel data in an image sensor are provided. A method of correcting saturated pixel data in an image sensor includes determining a weight function. The weight function indicates a correlation between color values of saturated pixels and color values of neighboring pixels. The saturated pixels are among a plurality of pixels which have a color value greater than a saturation threshold value. The neighboring pixels are among the plurality of pixels that are proximate to each of the saturated pixels. The method includes determining weight values of a neighboring pixels that are proximate to a first saturated pixel using the weight function. The method includes determining a weighted average value of the color values of each of the neighboring pixels using the weight values. The method includes correcting the color value of the first saturated pixel to the weighted average value.
