Claim Text:
1. A three-dimensional image capture apparatus, comprising: a single lens module; a first light guiding pipe, the lens module located in the first light guiding pipe, the first light guiding pipe extending parallel to an optical axis of the lens module; a second light guiding pipe, one end of the second light guiding pipe perpendicularly connected to one end of the first light guiding pipe and in communication with the first light guiding pipe, the second light guiding pipe extending perpendicularly to the first light guiding pipe; a first mirror located at a first intersection of the first light guiding pipe and the second light guiding pipe, the first intersection comprising a first slanted inner surface, the first mirror contacting the first slanted inner surface; an X-cube beam-splitting prism comprising a first transflective surface and a second transflective obliquely intersecting the first transflective surface, the first transflective surface being configured for reflecting light from a first viewing angle of an object through the lens module toward a first direction, the second transflective surface being configured for reflecting light from a second viewing angle of an object through the lens module to toward an opposite second direction; two image sensors for respectively detecting the light reflected by the first and second transflective surfaces, and generating parallax image signals; and a parallax processor for processing the parallax image signals from the image sensors to generate a 3D image; wherein the first mirror has a reflective surface inclined about 45 degrees with respect to the extension axes of the first light guiding pipe and the second light guiding pipe for reflecting the light from the first light guiding pipe to the second light guiding pipe, the beam-splitting prism is located at an end of the second light guiding pipe away from the first mirror, the first and second transflective surfaces being inclined a same angle with respect to the extension axis of the second light guiding pipe, the apparatus further comprises two third light guiding pipes, the two third light guiding pipes extend perpendicularly to and are in communication with the second light guiding pipe, the two third light guiding pipes extend opposite to each other from the end of the second light guiding pipe, the beam-splitting prism is located in a boundary among the second light guiding pipe and the two third light guiding pipes, the third light guiding pipes respectively guide the light reflected by the first and second transflective surfaces, the two third light guiding pipes are not parallel to the first light guiding pipe; and wherein the apparatus further comprises two fourth light guiding pipes and two second mirrors, the fourth light guiding pipes are respectively perpendicularly connected to the third light guiding pipes and in communication with the third light guiding pipes, each of the second mirrors being located at a second intersection of the corresponding third light guiding pipe and the corresponding fourth light guiding pipe for reflecting the light from the corresponding third light guiding pipe to the corresponding fourth light guiding pipe.
