METHOD OF CORRECTING SATURATED PIXEL DATA AND METHOD OF PROCESSING IMAGE DATA USING THE SAME

摘要

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.

1. A method of correcting saturated pixel data in an image sensor, the method comprising:
determining a weight function, the weight function indicating a correlation between color values of saturated pixels and color values of neighboring pixels, the saturated pixels being among a plurality of pixels which have a color value greater than a saturation threshold value, the neighboring pixels being among the plurality of pixels that are proximate to each of the saturated pixels; determining, using the weight function, a weight value for each of the neighboring pixels which are proximate to a first one of the saturated pixels; determining, using the weight value of each of the neighboring pixels, a weighted average value of the color values of the neighboring pixels; and correcting the color value of the first saturated pixel to the weighted average value.
