Abstract
Light is divided into transmitted light and reflected light by a half mirror 3. The transmitted light is photographed by a first imaging system and the reflected light is photographed by a second imaging system. In this case, a very-small binocular parallax is realized by parallax producing means 7S and 7K.
Claims9
A video comprising:
- light dividing means for dividing the light incoming from only one imaging window and emitted from an object, into transmitted light and reflected light;
- a first imaging system having at least an objective lens and an imaging device for imaging the transmitted light;
- and
- a second imaging system having at least an objective lens and an imaging device for imaging the reflected light, wherein:
- image inverting means for returning a mirror image formed by the reflected light to an orthoscopic image is provided for the second imaging system;
- and
- parallax producing means for producing a parallax for three-dimensionally viewing an image formed by the first and second imaging systems.
A videoscope, comprising:
- light dividing means for dividing the light incoming from an imaging window and emitted from an object, into transmitted light and reflected light;
- a first imaging system having at least an objective lens and an imaging device for imaging the transmitted light;
- and
- a second imaging system having at least an objective lens and an imaging device for imaging the reflected light;
- wherein image inverting means for returning a mirror image formed by the reflected light to an orthoscopic image is provided for the second imaging system;
- parallax producing means for producing a parallax for three-dimensionally viewing an image formed by the first and second imaging systems;
- and
- the image inverting means includes a mirror plane of a half mirror and is formed into an optical multilayer provided with a reflection characteristic by using a metallic film and a dielectric film.

- and
- image-capturing means for simultaneously capturing video-signal outputs into a frame memory, generated by the first and second imaging systems.
A display unit, comprising image synthesizing means for producing images for one frame by deleting predetermined areas of a first video signal and a second video signal which are provided with a parallax for three-dimensional viewing so as to leave central portions and arranging video signals of central portions to right and left and outputting the images for one frame as video signals;
- and
- image-capturing means for capturing a video-signal output supplied from the image synthesizing means into a frame memory.
