1. An image sensing device comprising:
a pixel array configured to output a pixel signal;
a comparator configured to output a comparison result signal by comparing a reference signal and the pixel signal;
a counter configured to output a count result signal having m bits by counting the comparison result signal; and
an image signal processor configured to output an image signal having n bits by correcting the count result signal,
wherein m and n are integers, and m is greater than n,
wherein the image signal processor is configured to generate the image signal by deleting first bits of the count result signal, when a value of the count result signal is greater than a first threshold value, and
wherein the image signal processor is configured to generate the image signal by deleting second bits of the count result signal, when the value of the count result signal is not greater than the first threshold value.
