Abstract
A 'Concurrent Projector-Camera' uses an image projection device in combination with one or more cameras to enable various techniques that provide visually flicker-free projection of images or video, while real-time image or video capture is occurring in that same space. The Concurrent Projector-Camera provides this projection in a manner that eliminates video feedback into the real-time image or video capture. More specifically, the Concurrent Projector-Camera dynamically synchronizes a combination of projector lighting (or light-control points) on-state temporal compression in combination with on-state temporal shifting during each image frame projection to open a 'capture time slot' for image capture during which no image is being projected. This capture time slot represents a tradeoff between image capture time and decreased brightness of the projected image. Examples of image projection devices include LED-LCD based projection devices, DLP-based projection devices using LED or laser illumination in combination with micromirror arrays, etc.
