ABSTRACT:
Methodology and circuitry for automatically effecting electronic camera movement to track and display the location of a moving object, such as a person presenting a talk to an audience. A fixed spotting camera is used to capture a field of view, and a moving tracking camera with pan/tilt/zoom/focus functions is driven to the present location of the moving object. Information for driving the tracking camera is obtained with reference to the pixel difference between a current image and a previous image within the field of view. A tracking algorithm computes the information necessary to drive the tracking camera from these pixel differences as well as data relative to the field of view of the spotting camera and the present tracking camera position.
