1. An image sensing system comprising:
an image sensor suitable for generating first actual brightness values corresponding to a captured image; and
an image processor suitable for sorting the first actual brightness values for each brightness period, generating a result signal corresponding to the sorted result, and compensating for the first actual brightness values for each brightness period based on the result signal and compensation information corresponding to a linearity error, wherein the compensation information represents a slope difference for each brightness period between an actual slope and a reference slope.
