Patent ID: 7986353

Claim:
An image sensing apparatus comprising a pixel array including a light-shielded area where light-shielded pixels are arranged, and an effective area where non-light-shielded pixels are arranged, each of the light-shielded pixels including a first photoelectric conversion unit, a first charge-voltage converter which converts charges generated in the first photoelectric conversion unit into a voltage, and a first amplification transistor functioning as a MOS transistor which receives, at a gate, the voltage converted by the first charge-voltage converter, and each of the non-light-shielded pixels including a second photoelectric conversion unit, a second charge-voltage converter which converts charges generated in the second photoelectric conversion unit into a voltage, and a second amplification transistor functioning as a MOS transistor which receives, at a gate, the voltage converted by the second charge-voltage converter, wherein a gate capacitance of the first amplification transistor is larger than a gate capacitance of the second amplification transistor.
