Classification: CPC H | IPC H

Claim 11:
12. An image sensing circuit comprising:
a pixel generating an image signal; and
a read-out circuit connected to the pixel, wherein:
the pixel includes:
a photoelectric conversion layer configured to convert incident light into first and second electric charges that are different from each other, and
a capacitor configured to receive the second electric charge from the photoelectric conversion layer and store the second electric charge, and the read-out circuit includes:
a transfer transistor which is disposed adjacent to the photoelectric conversion layer and configured to receive the first electric charge from the photoelectric conversion layer,
a floating diffusion which is connected to the transfer transistor and the capacitor and configured to receive the first and second electric charges,
the first electric charge passes through the transfer transistor as it flows from the photoelectric conversion layer to the floating diffusion and the second electric charge does not pass through the transfer transistor as it flows from the photoelectric conversion layer to the floating diffusion.
