Abstract
A computer-implemented method for utilizing a camera device to track an object is presented. As part of the method, a region of interest is determined within an overall image sensing area. A point light source is then tracked within the region of interest. In a particular arrangement, the camera device incorporates CMOS image sensor technology and the point light source is an IR LED. Other embodiments pertain to manipulations of the region of interest to accommodate changes to the status of the point light source.

12. A computer vision-based object tracking system, the system comprising:
-
an object; a point light source that is associated with the object such that the point light source moves when the object moves; and a camera device configured to track the object by tracking the point light source, the camera device being further configured to track the point light source within a region of interest that is less than an overall image sensing area. - View Dependent Claims (13, 14, 15)
