Abstract

A target (3, 207) is monitored using an image sensor (5, 201) for producing a signal indicative of an image received by the sensor, and processing the image signal. The image signal is processed using a comparator (105) for determining the amplitude of the image signal and for identifying any part or parts of the signal having an amplitude greater than a predetermined threshold (VTR). Location coordinates of the part or parts of the signal having an amplitude greater than the predetermined threshold are then determined.
