Abstract: A system for monitoring the motion of objects is configured to identify objects meeting predetermined criteria appearing in a scene and to track the motion of identified objects across the scene. In a particular embodiment the system is configured to compile statistical data for multiple points or regions to indicate one or both of: the frequency with which objects are initialised at that region or point; and the frequency with which initialised objects cross the region or point. The initialisation data will indicate the areas in the scene where objects are most frequently initialised. If the statistical data shows an area of the scene in which objects are never initialised this might indicate that there is an obstruction between objects that need to be tracked and the detector. The path data will indicate the paths most frequently followed by objects.

After a static time tuning (STT) table and a run time tuning (RTT) table have been established, the apparatus converts an output clock signal to generate a current RTT value at every predefined time and then compares the current RTT value with a reference RTT value generated in response to a STT value of the STT table, or with an interpolated result generated in response to the reference RTT value to generate a deviation value. Thus, through the deviation value, the output clock signal may be calibrated to address the target frequency without the assistance of external reference clock unit or locked loop unit after the STT table and the RTT table are established.
