Claim 15:
16. A visual sensor adapted to be capped with a cap comprising a reflector located on a side of the cap facing a lens of a visual sensor when the cap is on, the visual sensor comprising:
a radiating element configured to radiate in a predetermined wavelength range;
a light sensitive element comprising pixels sensitive only to the specific wavelength range and pixels sensitive to a different wavelength range, the light sensitive element outputting a first pixel map from the pixels sensitive only to the specific wavelength range and a second pixel map from the pixels sensitive to the different wavelength range; and
a processor for:
subject to the first pixel map corresponding to the second pixel map, determining that the visual sensor is not capped by the cap,
subject to the first pixel map not corresponding to the second pixel map, determining that the visual sensor is capped by the cap, and
taking an action, dependent on whether the visual sensor is capped or not capped, in accordance with a setting.
