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.

Abstract: An image sensor in which a shading phenomenon is decreased and the quality is increased includes a substrate comprising a first face on which light is incident, and a second face opposite to the first face and a plurality of unit pixels. Each of the plurality of unit pixels includes a photoelectric conversion layer in the substrate. The image sensor further includes a pixel separation pattern which separates unit pixels from the plurality of the unit pixels from each other, a plurality of color filters disposed on the first face of the substrate and arranged in a Bayer pattern, and a grid pattern disposed on the first face of the substrate and interposed within the plurality of color filters. A light-receiving area of the red color filter and a light-receiving area of the blue color filter are smaller than a light-receiving area of the green color filter.
