Patent ID: 8119965

Claim:
An image sensor provided with: a substrate; a first light receiving element provided for each of pixels obtained by dividing a substrate into a plurality of areas, provided on the substrate, receiving light incident upon one principal surface of the substrate, and generating a charge in accordance with an amount of light received; a second light receiving element provided for each of the pixels, provided at a position in behind side of the first light receiving element, receiving light incident upon the one principal surface and passing through at least one of the first light receiving element and the substrate, and generating a charge in accordance with the amount of light received; and a corrector configured so as to increase a signal level of a first electric signal based on the charge generated at the first light receiving element of a pixel, so that the higher a signal level of a second electric signal based on the charge generated at the second light receiving element of the same pixel is, the larger the increase amount is, the corrector thereby correcting the signal level of the first electric signal.
