PURPOSE:To obtain a video which is close to a natural view, by constituting a three- dimensional video photographing camera of the 2nd projecting mechanisms composed of mirrors which project images from the 1st projecting mechanisms as an upper and lower imaged united in one image, a relay lens which receives images from the 2nd projecting mechanisms, and a lens box which houses the mechanisms and lens. CONSTITUTION:On the image side of a camera box 6 the lens box 11 of a lens section 33 is mounted and on the object side of the box 6 a pair of right and left master lenses 12 and 13 are provided in such a way that their central positions are set conformably to the eye intervals of human beings in the right-left direction and shifted at an appropriate interval in accordance with the size of a film in the vertical direction. Images B1 and C1 are changed in projecting direction by the 1st projecting mechanisms 16 and 17 composed of mirrors having hyperplane mirror surfaces and sent to a relay lens 20 as an aberration-free upper and lower images united in one body by the 2nd projecting mechanisms 18 and 19. Then images B2 and C2, whose brightness is doubled and light quantities lost by field lenses and mirrors are supplemented by the relay lens 20, are formed on a film placing surface 7 as an upper and lower images united in one image. Therefore, a video which is close to a natural view is obtained.
