Distortion correction with different correction accuracy is performed on images acquired in accordance with an image pick-up mode for a 3D moving image, a 3D still image, and the like, and an image cut-out process corresponding to an optical axis deviation amount of each of right and left photographing optical systems is also performed thereon, whereby optical axis deviation is corrected. In this case, an optical axis deviation amount corresponding to a current image pick-up mode is read out from among optical axis deviation amounts after distortion correction, the optical axis deviation amounts being stored in advance into an EEPROM at the time of adjustment before shipment and corresponding to respective image pick-up modes. Distortion correction corresponding to the current image pick-up mode is performed on right and left images acquired in accordance with the current image pick-up mode. Then, a cut-out process of images for stereoscopic display from the images with a full angle of view after the distortion correction is also performed on the basis of the read-out optical axis deviation amount.
