  • Patent number: 11877064
    Abstract: This patent provides a novel stereoscopic imaging system. In the preferred embodiment, the improved stereoscopic imaging system would be incorporated onto a smart phone, which is called the stereoscopic smart phone (SSP). The SSP would work in conjunction with one or more stereoscopic head display units (SHDUs). Once this system is operational, it will allow significant improvements to obtaining stereoscopic imagery. One novel aspect of this patent comprises wherein the stereoscopic cameras on the SSP can move in position to alter stereo separation distance and change the convergence to optimally image a scene.

  • Patent number: 9152014
    Abstract: Example stereoscopic image photographing apparatuses and methods are disclosed. A disclosed example stereoscopic image photographing apparatus includes a shutter unit including a first region and a second region that are defined based on a gravity direction as an absolute basis regardless of an arrangement of the stereoscopic image photographing apparatus. A first image signal is generated by converting a first optical signal input through a first region of the shutter unit, and a second image signal is generated by converting a second optical signal input through the second region. In addition, a stereoscopic image is generated using the first image signal and the second image signal. Thus, a stereoscopic image with a difference between right and left views may be generated regardless of an orientation of the stereoscopic image photographing apparatus.

  • Patent number: 6259865
    Abstract: An adapter enables three-dimensional motion photography by means of a single camera, video or film, that includes a single lens system and image pickup. The adapter is engageable to a conventional camera. An optical system within the adapter includes a mirror for detecting a second, distinct perspective of a field-of-view. The two perspective views are orthogonally polarized and applied to a single switchable liquid crystal polarization rotator that is driven by a periodic SYNC signal derived from the camera. A polarization filter receives the output of the rotator which alternately passes perspective views unaltered and rotated by ninety degrees in polarization, providing alternating frames of one or another perspective view to the camera. The stream of alternating perspectives provides a three-dimensional viewing effect when processed by conventional video and film systems.

The printer uses a monitor for sequentially displaying 2D images. A projection lens is used to project the displayed 2D images onto the print material. A tilting mechanism is used to tilt the print material for changing the projection angles. In order to correct for the distortion of images projected on the print material due to tilting, the 2D images are geometrically transformed according to the tilting angles. The same printer can be used to make 2D prints on regular photographic paper. The printer can be equipped with a plurality of projection lenses with different focal lengths so that pictures of different magnification factors can be made.
