An image capturing device includes: an image capturing element having a first image capturing region that captures an image of a photographic subject and outputs a first signal, and a second image capturing region that captures an image of the photographic subject and outputs a second signal; a setting unit that sets an image capture condition for the first image capturing region to an image capture condition that is different from an image capture condition for the second image capturing region; a correction unit that performs correction upon the second signal, for employment in interpolation of the first signal; and a generation unit that generates an image of the photographic subject that has been captured by the first image capturing region by employing a signal generated by interpolating the first signal according to the second signal as corrected by the correction unit.
