Abstract: Provided are an imaging apparatus, an image processing apparatus, an image processing method, and a non-transitory computer readable recording medium storing an image processing program capable of appropriately correcting both of focus breathing and distortion. Focus breathing is corrected by subjecting image data to magnification/reduction processing according to a magnification/reduction rate determined for each focus position. Distortion is corrected through image processing to the image data with focus breathing corrected. In correcting distortion, distortion appearing in image data after correction of focus breathing is corrected.
