  • Patent number: 7218376
    Abstract: An adapter for a three-dimensional moving image photographing device includes a lens unit and a half-reflecting mirror. The lens unit comprises entrance and exit lens parts, each including release lenses disposed in the middle of the lens unit. The entrance and exit lens parts are ranged symmetrically to each other, The lens unit has an entrance pupil point formed outside the entrance lens part. The half-reflecting mirror is disposed on a light axis of a photographing lens between a first total reflecting minor and the lens unit while being inclined at a prescribed angle relative to the light axis for reflecting a moving image having been introduced along a second light axis and reflected by a second total reflecting minor, and transmitting a moving image having been introduced along a third light axis and reflected by a third total reflecting mirror and the first total reflecting mirror.
