An image sensor according to the present invention includes a charge forming portion forming charges by photoelectric conversion and a charge transfer region including a charge increasing region for increasing the amount of charges. The image sensor is so formed as to increase dark current generated in at least part of the charge forming portion and the charge transfer region in the charge increasing region for calculating an increasing ratio for the charges on the basis of an output value resulting from a charge signal of the increased dark current. |
