Patent ID: 7468508

Claim:
A system for projecting an image and adjusting a data frequency of a video signal during image projection, comprising: a) a laser assembly for generating a laser beam; b) a scanner, including a scan mirror oscillatable at a scan frequency about a scan axis, for sweeping the laser beam as a pattern of scan lines during oscillation of the scan mirror, each scan line having a number of pixels; c) a detector for detecting the scan frequency of the scan mirror; d) a controller operatively connected to the laser assembly, the scanner and the detector, for causing selected pixels along the scan lines to be illuminated, and rendered visible, by the laser beam to produce the image, and for automatically determining in real time an optimal value for the data frequency based on the scan frequency detected by the detector; and e) a host directly connected over a bi-directional control channel to the controller, for adjusting the data frequency to the optimal value under direct control of the controller over the bi-directional control channel, and for supplying the video signal with the data frequency at the optimal value.
