摘要:
A projection capture system includes a camera to capture video of objects in a capture space, and a light emitting diode (LED) projector to illuminate the objects in the capture space and to project images captured by the camera into a display space. The projector includes a sequential display mode for sequentially displaying red, green, and blue light to project images captured by the camera into the display space, and a camera flash mode for simultaneously displaying red, green, and blue light to provide white light for illuminating the objects in the capture space during video capture.

A projector apparatus includes: a polarization beam splitter block assuming a shape of a rectangular parallelepiped that includes two end surfaces ranging orthogonally relative to a polarization beam splitting surface and four side surfaces perpendicular to the end surfaces; a light source disposed so as to face opposite one of the side surfaces of the polarization beam splitter block; an illumination optical system that is disposed between the light source and the polarization beam splitter block, and converts illuminating light emitted from the light source to substantially parallel light so as to direct the substantially parallel light to the polarization beam splitter block; a reflection-type liquid crystal display element that is disposed so as to face opposite an illuminating light output surface of the polarization beam splitter block, through which an illuminating light having undergone polarization separation at the polarization beam splitting surface is output, and includes a rectangular display area through which the illuminating light having undergone the polarization separation is modulated to modulated light and the modulated light is output to the polarization beam splitter block; and a projection optical system that forms a projection image with light obtained by subjecting the modulated light to polarization separation at the polarization beam splitting surface, wherein: the reflection-type liquid crystal display element is disposed so as to set shorter borders of the rectangular display area parallel to the end surfaces.

A compact optical projection apparatus. An apparatus for light projection includes at least one illumination device; a cover prism including a curved surface positioned to receive illumination light rays and a total internal reflection surface positioned to internally reflect the light rays towards an asymmetric reflector surface positioned opposite the total internal reflection surface, the asymmetric reflector surface configured to reflect the received light rays out of the cover prism at an emitter side of the cover prism; a spatial light modulating the illumination light rays with image data to form image light rays; a reverse total internal reflection (RTIR) prism positioned between the spatial light modulator and the emitter side of the cover prism and further comprising a total internal reflection surface configured to totally internally reflect the image light rays out of the RTIR prism into a light projection device. Additional apparatus are disclosed.

A projection display device includes: a light source unit including light sources emitting light in a plurality of colors, condenser lenses and a color combining optical element; a total reflection prism that totally reflects a combined light flux from the color combining optical element so as to be guided to an image forming means; and a projection lens. At least one of; an entry surface of the color combining optical element through which substantially parallel light fluxes from the condenser lenses enter, an exit surface of the color combining optical element through which the combined light flux exists, and an entry surface of the total reflection prism through which the combined light flux enters, is formed as a free curved surface where a shape of a section of the combined light flux is altered so as to be matched with a shape of an outline of the display area.
摘要:
Described are handheld devices with combined image capture and image projection functions. One embodiment includes modulating and capturing a light beam along the sam optic path. In another embodiment, the optical components are operable to switch between projection (122) and capture modes. In yet another embodiment, the optical components may be formed on the same semiconductor substrate thereby increasing functionality.

The electronic device includes a projector device that projects an image formed by an optical image formation element, an imaging device that captures an image of an object to be photographed so that an imaging range includes the range of projection by the projector device and outputs an image signal, an image change detection unit that detects change of the image signal after having excluded the projection range from the range photographed by the imaging device, and a command unit that issues a command related to operation of the projector device according to the region within the imaging range in which change has been detected by the image change detection unit.
摘要:
A small portable 'pocket pen size' (12) projector/image grabber device for allowing an individual to gather, share and exploit information in a projected format in real time, day or night, with other individuals on demand. An ultra high density MEMS (14) mirror display array provides a 1024 x 768 line projection display. An on axis 512 x 384 color CCD imager (28) is also included resulting in a digitally-aligned image capture and overlay display capability. A sequentially addressed three color chip laser and low cost plastic optics provides full color high resolution bright displays for group viewing. 3-D color imaging is also provided by a binocular attachment to the device which permits the capturing of three-dimentional imagery.
摘要:
A dual-mode display system (20), for applications such as viewfinders/displays in a digital still camera or video camcorder, may include a single spatial light modulator microdisplay (22) that can be used both to provide a virtual image at a viewing location, such as near-eye viewing port (28), ant to provide a real image that can be projected onto a surface such as a projection screen (34). The projection screen may be on an exterior surface of the camera, it may be extendable from the device such as with a camcorder, or it may be an external screen such as a on a wall, desk, piece of paper, or a traditional projection screen. The optical paths for the near-eye and projection modes may be entirely different, with only the SLM (22) in common, or they be largely or entirely common paths. Different light sources may be used for the two modes, or it may be the same light source. The display system may switch between the two modes by selecting one of two different light sources or by moving an optical element, such as a lens or reflective surface (24).
