Smart tracking system

摘要

A smart tracking system includes a digital processor for selectively processing error signals representing the angular error between a tracked subject and the orientation of the tracking device/camera. In one embodiment, the user selects a set of data values representating the operating parameters of the system in a specific operational mode. The processor uses the selected variables to perform a series of computations which selectively modify the angular error signals in a manner that will produce a video picture which is visually and aesthetically pleasing to human viewers. In a second embodiment, the set of data values characterizing the operational mode of the system automatically are selected by the processor based on the past history of the subject's motion and the current operation mode of the system.
