PROBLEM TO BE SOLVED: To conduct processing with respect to distortion aberration correction of an imaging signal at a high-speed and eliminate unnaturalness of the image as a whole. SOLUTION: The signal processing unit corrects distortion aberrations of an imaging optical system, with respect to an image signal of an object optical image made incident via the imaging optical system and corrects the distortion aberration in a second direction different from a first direction, on the basis of the distortion aberration in the first direction. |
