  • Method of correcting saturated pixel data and method of processing image data using the same
    Patent number: 9294688
    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.

  • Method and device for processing an image to remove color fringe
    Patent number: 9047679
    Abstract: In image processing, a color fringe is removed. The processing includes selecting a maximum gradient magnitude among gradient magnitudes for each of color components in an image, calculating a boundary of a dilated near-saturation region in the image, detecting a transition region in the image according to the maximum gradient magnitude and the dilated near-saturation region, and removing a color fringe from the transition region.
