Abstract
A small portable “pocket pen size” 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 mirror display array provides a 1024×768 line projection display. An on-axis 512×384 color CCD imager 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-dimensional imagery.
