Method for embedding projection capabilities into digital cameras

Disclosed is a method for embedding projection capabilities into digital cameras. Benefits include improved functionality and improved user satisfaction.

Description

              The disclosed method provides a bi-directional camera interface, a standard input device used for video capture/still pictures and a projection output for display. Implementation of the disclosed method would require development of a small form‐factor projection camera interface utilizing technology similar to that of projectors. Possible implementations may include a one lens version (see Figure 1) or a two lens version (see Figure 2).

              Conventional Digital PC cameras are limited to input only either by taking snapshots or short videos. An implementation of the disclosed method would provide these standard functions and not be limited to showing the video on a monitor or TV. The camera would enable the user to project images at a short range on a projection screen or white surface.

              Limitations may apply to the distance for projecting images on screen surfaces. As the unit is improved so that it draws less power, the camera may fit into a more compact projection unit.

Advantages

              Conventional Digital PC cameras are limited to input such as snapshots or short videos. By enabling this technology, the end‐user’s experience with digital cameras improves

exponentially. The disclosed method could be used for displaying slide shows, producing meeting prese...
