A correction process is realized by a simpler method. An imaging apparatus 1 includes an image acquisition unit 51, a template storage unit 62, an adaptive position specifying unit 53, and a distortion correction processing unit 55. The image acquisition unit 51 acquires an image including a predetermined subject. The template storage unit 62 stores a template including correction degrees of respective positions in a shape corresponding to a correction target region of the predetermined subject, the correction degrees being different at the respective positions. The adaptive position specifying unit 53 specifies coordinates adapting to a template in the image. The distortion correction processing unit 55 corrects the image on the basis of coordinates specified by the adaptive position specifying unit 53 and the correction degree included in the template.
