System and camera for controlling depth of field in three-dimensional photography

摘要

In the exemplary embodiments of the invention disclosed, a system especially adapted for producing stereoscopic pictures in general photography includes a camera having a plurality of lenses aligned in a row with the optical axes substantially in parallel and the endmost lenses spaced apart by a distance that is productive of a three-dimensional depth of field in the system which matches or exceeds the two-dimensional depth of field of the camera lenses at least under average photographic conditions. Such matching of the two and three-dimensional depths of field, where the limits of the two-dimensional depth of field are based on the lenticule width w of the stereoscopic picture, provide sharply focused, solid stereoscopic images of all objects within the two-dimensional capabilities of the camera lens.
