Abstract: An image sensor is provided. The image sensor includes: pixel groups; a readout circuit configured to output full pixel values respectively corresponding to the pixel groups and sub pixel values respectively corresponding to the pixel groups, wherein a full pixel value is generated based on pixel signals of all pixels in a first pixel group, and a sub pixel value is generated based on some of the pixel signals in the first pixel group; and an image signal processor configured to: generate, based on the full pixel value indicating the first pixel group is a saturation pixel group, a color ratio of the saturation pixel group by using a target sub pixel value corresponding to the saturation pixel group; and compensate for the full pixel value of the saturation pixel group based on the color ratio of the saturation pixel group.

Abstract: An image sensor and an image processing system in which the image sensor includes a sensing unit configured to generate a plurality of images having different luminances with respect to a same object, a pre-processor configured to merge n images (n is a natural number equal to or greater than 2) except for at least one of the plurality of images to generate a merged image, and an interface circuit configured to output the at least one image and the merged image to an external processor.
