Abstract
Image-capturing device includes: an image sensor that includes a first pixel and a second pixel, each having a filter unit that can be switched to a light-shielding state in which light is blocked or to a transmissive state in which light is transmitted, a photoelectric conversion unit that generates an electric charge through photoelectric conversion of light transmitted through the filter unit and an output unit that outputs a signal based upon electric charge generated at the photoelectric conversion unit, and; a correction unit that corrects a signal output from the output unit of the first pixel while the filter unit of the first pixel is in a transmissive state, based upon a signal output from the output unit of the first pixel with the filter unit of the first pixel set in a light-shielding state and with the filter unit of the second pixel set in a transmissive state.
