PROBLEM TO BE SOLVED: To provide a three-dimensional image photographing method by which a three-dimensional image observed by naked eyes is easily taken. SOLUTION: In this three-dimensional image photographing method in which the three-dimensional image is obtained by changing a focusing position on an object image in accordance with an object distance and performing photographing several times, photographing is performed to satisfy a condition x2>=Af<2> (x1-b)/ Af<2> -R(x1-b)}+b when it is assumed that a distance from the front of a photographic lens 1 to the focusing position where the object distance is shorter is x1, a distance from the front of the lens 1 to the focusing position where the object distance is longer is x2, the focal distance of the lens 1 is (f), a distance from the front side focus of the lens 1 to the front of the lens 1 is (b), the radius of the minimum circle of confusion of the lens 1 is R and a larger value out of the emitting side numerical apertures of two photographic images in the lens 1 is A in the case of performing photographing twice in photographing performed several times. |
