Projector-camera systems (pro-cam), also called camera-projector systems, [1] augment a local surface with a projected captured image of a remote surface, creating a shared workspace for remote collaboration and communication. Projector-camera systems may also be used for artistic and entertainment purposes. [2]
R-D1 was jointly developed by Seiko Epson and Cosina and manufactured by the latter, which also builds the current Voigtländer cameras. It uses Leica M-mount lenses or earlier Leica screw mount lenses with an adapter. An unusual feature to note on the R-D1 is that it is a digital camera that has a manually wound shutter with a rapid wind lever ...

These earlier types of projectors were mostly replaced with digital video projectors throughout the 1990s and early 2000s, [1] but old analog ...
Combining a pico projector with a webcam, a laser pointer, and image processing software enables full control of any computing system via the laser pointer. Pointer on/off actions, motion patterns (e.g., dwell, repetitive visit, circles, etc.) and more can all be mapped to events which generate standard mouse or keyboard events, or user ...
In 2004, Epson introduced their R-D1 (the first digital rangefinder camera on the market), which supports the Leica M mount and Leica M39 mount lenses with an adapter ring.
