Patent ID: 7302174

Claim:
An image capture and projection arrangement, comprising: a) a laser source for generating a laser beam; b) a scanner for sweeping the laser beam to form a scan line having a number of pixels arranged along a first direction, and for sweeping the scan line along a second direction generally orthogonal to the first direction to form a raster pattern of scan lines; c) a detector for receiving light from the scan lines scattered off a target; and d) a controller for controlling the laser source to illuminate selected pixels on the scan lines to project an image on a projection surface during a display mode of operation, and for controlling the detector to receive the light from the scan lines scattered off the target, each pixel of the scan lines being serially received in its turn, to capture an image of the target during a camera mode of operation, the controller being operative for detecting the number of pixels in at least one of the scan lines occupied by the target in the camera mode, and for changing a size of the target image in response to the detection.
