Three-dimensional video photographing lens
专利汇可以提供Three-dimensional video photographing lens专利检索，专利查询，专利分析的服务。并且PURPOSE: To obtain a video which is close to a natural view, by constituting a lens for photographing three-dimensional videos of two master lenses, two sets of field lenses, the 1st and 2nd projecting mechanisms, a relay lens, and a lens box which houses the above-mentioned lenses and mechanisms and projecting the two images from the master lenses on a film surface as an upper and lower images united in one picture.
CONSTITUTION: Images B and C of an object inputted from a right and left master lenses 12 and 13 are firstly passed through field lenses 14 and 15 and form aberration-free images B
1 and C
1 due to the excellent image forming forces of the field lenses. Then the projecting directions of the images B
1 and C
1 are changed by the 1st projecting mechanisms 16 and 17 composed of mirrors having hyperplane mirror surfaces and the images B
1 and C
1 are sent to a relay lens 20 by the 2nd projecting mechanisms 18 and 19 composed of similar mirrors as an aberration-free upper and lower images united in one image. Then aberration-free images B
2 and C
2 , whose brightness is doubled and light quantities lost by the field lenses and mirrors are supplemented by he relay lens 20, are formed on a film surface 7 as an upper and lower images united in one image. Therefore, a video which is close to a natural view is obtained.
