Classification: CPC G  H | IPC G  H

Claim 8:
9. The image sensing device according to claim 1, wherein the second pixel includes:
a photoelectric conversion element configured to generate and accumulate photocharges by performing photoelectric conversion of incident light reflected from the target object;
a plurality of circulation gates disposed in regions corresponding to four sides of a rectangular ring shape surrounding the photoelectric conversion element, and configured to induce movement of the photocharges by partially generating an electric field in different regions of the photoelectric conversion element based on circulation control voltages; and
a plurality of transfer gates disposed in regions corresponding to vertex points of the rectangular ring shape, and configured to transmit the photocharges to a corresponding floating diffusion (FD) region based on transfer control signals.
