RASTER SCANNING FOR DEPTH DETECTION
First Claim
1. A method comprising:
- raster scanning light over an object in a field of view of a camera;
receiving a reflected image of the light from the object at a detector;
determining a distance to the object based on the reflected image; and
dynamically modifying the field of view by varying a range over which the raster scanning is performed based on whether the object has been fully scanned.

Abstract
Techniques are provided for determining distance to an object in a depth camera'"'"'s field of view. The techniques may include raster scanning light over the object and detecting reflected light from the object. One or more distances to the object may be determined based on the reflected image. A 3D mapping of the object may be generated. The distance(s) to the object may be determined based on times-of-flight between transmitting the light from a light source in the camera to receiving the reflected image from the object. Raster scanning the light may include raster scanning a pattern into the field of view. Determining the distance(s) to the object may include determining spatial differences between a reflected image of the pattern that is received at the camera and a reference pattern.

9. A depth camera, comprising:
-
a light source that emits light; a scanning element in optical communication with the light source; logic that controls the scanning element to scan the light from the light source over a field of view of the depth camera; a light detector that receives a reflected image of the scanned light from an object within the field of view; and logic that determines a distance to the object based on spatial properties of the reflected image. - View Dependent Claims (10, 11, 12, 13, 14)

15. A method of scanning to determine depth information, the method comprising:
-
transmitting light from a light source in a camera; controlling a scanning element while transmitting the light to scan the light in a field of view of the camera; receiving a reflected image from an object in the field of view of the camera while controlling the scanning element; analyzing spatial properties of the received image; and determining a distance to the object based on the analyzing spatial properties of the received image. - View Dependent Claims (16, 17, 18, 19, 20)
