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.

Description

technical field [0001] The present invention relates generally to electronic displays and, more particularly, to laser projection displays and their use as image acquisition devices. Background technique [0002] Electronic cameras have historically had many disadvantages, including high cost, lack of persistence, size, weight, limited flexibility, and more. Also, conventional cameras typically rely on a flash unit to provide proper illumination. These flash units are generally very battery draining, which tends to shorten the camera's battery life and make it less useful. Also, photographers often have to wait for the battery to charge the flash unit before taking each picture. Furthermore, the use of flash units produces a number of unwanted side effects, including photographically distorting and disruptive reflections. [0003] Additionally, electronic cameras typically employ one or more display screens for viewing images or as a viewfinder. These screens add to the ...
