The system comprises at least one image sensor 100 for imaging an indicium; an illuminator 102 for illuminating the indicium; and a processor 104 adapted to receive images of the indicium from the sensor and process the image to determine the indicium. The illuminator is adapted to emit a series of light pulses of varying intensity. The pulses may consist of high- or low-power pulses, which may be interspersed. The system may find application in identifying vehicle registration or license plates. The system may also comprise a means of detecting a moving object, and this can be used to trigger the illuminator. A proximity detector 112 could also be included so that the illumination is stopped when a human head is detected in the field of view. The system may be powered by a renewable energy source 106 such as solar or wind energy, and may also comprise a GPS device.
