Abstract: Provided are an image processing circuit, a system-on-chip including the same, and a method of improving quality of a first image. The image processing circuit includes a tuning circuit configured to receive a segmentation map including pixel-by-pixel class inference information of the first image and a confidence map including confidence of the class inference information, determine classes of respective pixels of the first image, correction effects for each pixel of the image, and correction values indicating intensity of the correction effects based on the segmentation map and the confidence map, and generate a correction map based on the classes and the correction values of the respective pixels; and at least one correcting circuit configured to generate an enhanced image by applying correction effects according to the correction values to the respective pixels of the first image based on the correction map.

Abstract: A processor-implemented method with super resolution includes: determining a direction type of an input image based on a gradient of the input image; acquiring a first intermediate image that is a super-resolution image corresponding to the input image based on a residual look-up table (LUT) corresponding to a kernel set mapped to the determined direction type; determining a LUT strength map of the input image based on the gradient of the input image and a preset tuning parameter; and generating an output image that is a super-resolution image of the input image based on the LUT strength map and the first intermediate image.

Abstract: An image signal processor includes a down-scaling circuit that generates a first image signal by down-scaling an input image signal, an image processing engine including a first recomposition circuit that generates a target image signal based on the first image signal, a first up-scaling circuit that generates a third image signal based on a second image signal generated by the image processing engine, a second recomposition circuit that generates an output image signal based on the third image signal, a second up-scaling circuit that generates a fourth image signal by up-scaling the first image signal, and a correction information generation circuit that generates an image information signal by extracting, from the input image signal and the fourth image signal, information about an image quality loss of the first image signal, and transmits the image information signal to the first or the second recomposition circuit depending on a mode.
