Abstract:
1. A stereoscopic image pick-up apparatus, comprising: a plurality of image pick-up units each including: a photographing optical system; and an image pick-up element which subjects a subject image formed via the photographing optical system to photoelectric conversion, the plurality of image pick-up units picking up a plurality of images having a parallax between the plurality of image pick-up units; a first storage unit which stores therein a distortion correction formula which is set for each of a plurality of image pick-up modes, the distortion correction formula having correction accuracy which is different for each of the plurality of image pick-up modes; a distortion correction formula acquisition unit which acquires a distortion correction formula corresponding to a current image pick-up mode from among the distortion correction formulae stored in the first storage unit; a second storage unit which stores therein a previously detected optical axis deviation amount of each photographing optical system included in the plurality of image pick-up units, the optical axis deviation amount having been subjected to distortion correction using the distortion correction formula which is set for each of the plurality of image pick-up modes; an optical axis deviation amount acquisition unit which acquires an optical axis deviation amount corresponding to the current image pick-up mode, on the basis of: the optical axis deviation amount of each photographing optical system stored in the second storage unit; and the current image pick-up mode; an image pick-up control unit which acquires the plurality of images from the plurality of image pick-up units in accordance with the current image pick-up mode; a distortion correction unit which performs distortion correction on the plurality of images acquired by the image pick-up control unit, on the basis of the distortion correction formula which is acquired by the distortion correction formula acquisition unit correspondingly to the current image pick-up mode; and an image cut-out unit which performs a cut-out process of images for stereoscopic display on the plurality of images acquired by the image pick-up control unit, on the basis of the optical axis deviation amount acquired by the optical axis deviation amount acquisition unit correspondingly to the current image pick-up mode, wherein the photographing optical systems are adjusted so that optical axes of the photographing optical systems coincide with each other.
