PROBLEM TO BE SOLVED: To provide a three-dimensional(3D) optical camera capable of obtaining a group of photographing images having short depth of field. SOLUTION: Since the 3D optical camera is provided with a scanning mechanism part 30 for scanning a subject so as to photograph it while relatively moving a photographing camera part 40 for photographing the subject and the subject and a reverse projection processing part 53 for carrying out image reconstitution for generating a 3D subject image by reversely projecting photographing data photographed in respective scanning positions to respective grating points of a 3D grating group virtually set in a subject area, a group of photographing images constituting the 3D subject image and having short depth of field, i.e., a group of photographing images arranged in the Z axis direction of the subject which is the depth direction of the subject and having short depth of field, can be obtained. |
