    Abstract: An image signal processor is provided. The image signal processor includes a white balancing block which performs white balancing on a raw RGB image of a Bayer pattern received from an image sensor on a kernel basis or in a kernel unit, a green generation block which performs cross-binning on white-balanced G pixel to generate a first green pixel, and adds a high-frequency component to which a preset weight is applied to generate a binned green pixel, a red-blue generation block which generates a U pixel and a V pixel indicating directionality, on the basis of the binned green pixel, a white-balanced R pixel, and a white-balanced B pixel, and merges the binned green pixel to each of the U pixel and the V pixel to generate a binned red pixel and a binned blue pixel and an inverse white balancing block which performs an inverse white balancing on the binned red pixel, the binned green pixel, and the binned blue pixel to output a final binning image.

    Abstract: A method of operating an image sensor, the image sensor including a pixel array of a plurality of red pixels, a plurality of green pixels, a plurality of blue pixels, and a plurality of white pixels, includes selecting a first green pixel and a second green pixel arranged on a first axis parallel to a first diagonal direction, selecting a third green pixel and a fourth green pixel arranged on a second axis parallel to a second diagonal direction, generating a first green binning pixel by performing a first diagonal binning operation on the first green pixel and the second green pixel, generating a second green binning pixel by performing a second diagonal binning operation on the third green pixel and the fourth green pixel, and generating image data corresponding to the first green binning pixel and the second green binning pixel.
