Claim Text:
1. An imaging apparatus comprising: an imaging element which images an object through a photographing lens to generate an image signal; a correction value calculating unit which 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; and a correction unit which corrects frequency characteristics of the plurality of frequency components in accordance with the correction values calculated, wherein the correction value calculating unit calculates the correction value for each of the frequency components from lens frequency characteristic information set in association with each of the aperture values for the photographing lens and pixel pitch information about the imaging element, and wherein the frequency components are a high-frequency component and a low-frequency component, and the correction value calculating unit calculates, for the high-frequency component, a correction value that decreases as the aperture value increases in a range above a value predetermined by the lens frequency characteristic information, and for the low-frequency component, a correction value that increases as the aperture value increases in the range above the value predetermined by the lens frequency characteristic information.
