A digital camera includes: an image sensor that captures an image of a subject and outputs an image signal; and a control device that engages the image sensor to capture an image at an exposure value having been set, makes a decision as to whether or not an overflow or an underflow deviating from a dynamic range of the image sensor manifests, calculates an exposure correction quantity with which the exposure value having been set is to be corrected in order to reduce the overflow or the underflow based upon results of the decision and engages the image sensor to capture a new image at an exposure value having been corrected in correspondence to the exposure correction quantity.
