1. An image binning method of an image sensing apparatus, the image binning method comprising:
receiving a raw image of a Bayer pattern from a pixel array;
outputting median values for each kernel based on performing an analog binning process on the raw image of a unit kernel having an asymmetrical arrangement with respect to different colors; and
outputting a binned image based on performing a digital binning process on at least one of the median values,
wherein the analog binning process further comprises summing a first pixel and a second pixel of a same color that are provided in a first diagonal direction to each other in a unit kernel and outputting a summed result as a median value, and
wherein the digital binning process further comprises summing and outputting the median value and a third pixel of the same color as the first pixel and the second pixel and as a pixel value of the binned image for the color of the first pixel, the second pixel, and the third pixel.
