| Title: |
Audience Scanning Laser Display Projector and Associated Methods |
| Abstract: |
An apparatus and method for an audience scanning laser display projector
includes a laser projector capable of generating a laser beam output
having a predetermined beam path, scan area and beam wavelength. A beam
position sensor is associated with said laser projector. A camera capable
of capturing an image of the audience using light of a wavelength other
than the beam wavelength, is disposed relative to said laser projector so
that the captured image includes the area scanned by the laser beam. A
processor is operably connected with said laser projector, said beam
position sensor and said camera, said processor generating a table
corresponding to the camera image of the audience, and containing
software capable of identifying location of faces in the audience image
and comparing face locations with beam position so as to signal said
laser projector to attenuate the beam when scanning over a face location.
