Abstract
An imaging apparatus includes an imaging element, a correction value calculating unit, and a correction unit. The imaging element images an object through a photographing lens to generate an image signal. The correction value calculating unit calculates correction values for a plurality of frequency components of the image signal, the correction values corresponding to an aperture value acquired when the object is imaged through the photographing lens. The correction unit corrects frequency characteristics of the plurality of frequency components in accordance with the correction values calculated.
