Abstract: An image processing device includes a guided image filtering circuit and an image summation circuit. The guided image filtering circuit is configured to receive an input image including a green channel, a red channel and a blue channel, and to generate a corrected red channel and a corrected blue channel by applying a guided filter with respect to the red channel and the blue channel based on the green channel. The image summation circuit is configured to generate an output image by summing the green channel, the corrected red channel, and the corrected blue channel.

Abstract: In an image processing device, a color transformation circuit is configured to generate a color difference based on a first image of normal exposure and a second image of under exposure. A color fringe detection circuit is configured to detect color fringe in the first image, and to generate color fringe detection information based on the detected color fringe. A weight map formation circuit is configured to generate a weight map based on the color fringe detection information and the color difference. An image fusion circuit is configured to generate a third image, in which the detected color fringe is suppressed, based on the color difference and the weight map.
