Abstract: An image processing circuit, an image signal processor including the same, and an image processing method are disclosed. The image processing circuit may include a contents-aware circuit configured to receive histograms of a current image and a previous image, classify content for each pixel of the current image, and generate a shifting value representing a color shifting effect for each pixel of the current image, a color shifting circuit configured to generate an enhanced image by applying color shifting depending on the shifting value to each pixel of the current image, based on the shifting value, and a histogram generator configured to generate a histogram of the current image based on the classified content of the current image, wherein the generated histogram of the current image is used to generate a shifting value of a subsequent image.
