The image capturing apparatus includes an image sensor that is provided with a first photoelectric conversion characteristic, a second photoelectric conversion characteristic being different from the first photoelectric conversion characteristic and a third photoelectric conversion characteristic being a transient characteristic between the first photoelectric conversion characteristic and the second photoelectric conversion characteristic; and a characteristic converting section to convert the first photoelectric conversion characteristic, the second photoelectric conversion characteristic and the third photoelectric conversion characteristic to a reference photoelectric conversion characteristic. The first photoelectric conversion characteristic is a linear characteristic, the second photoelectric conversion characteristic is a logarithmic characteristic and the reference photoelectric conversion characteristic is either a linear or a logarithmic characteristic.
