Abstract
A method and apparatus are provided to capture images using a laser projection display (LPD). In a full color LPD camera, three lasers (red, blue, and green) are deployed to scan an image and receive reflected laser light therefrom. The reflected laser light may be analyzed and assembled into a picture. The LPD may also be used to display the picture, to operate as a viewfinder, to print the picture, to operate as a range finder, and the like.
