An imaging apparatus comprising: a subject recognition section for recognizing a subject image at rest on an imaging surface and a subject image moving on the imaging surface, an image shift-amount detection section for detecting a positional shift on the imaging surface, and an image composition section for executing composition processing by additive composition of the respective image data if the subject recognition section recognizes the subject image as the subject image at rest on the imaging surface and for correcting the positional shift of the moving subject image detected by the image shift-amount detection section if the subject recognition section recognizes the subject image as the subject image moving on the imaging surface and then, for executing the composition processing by relatively bright composition or additionally averaged composition of the respective corrected image data so as to generate taken image data with multiple exposure.
