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.

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).
