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.
