Claim 6:
7. A visual sensor adapted to be capped with a cap including at least one light-transmitting part comprising a section transparent only to a specific wavelength range, the visual sensor comprising:
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 pixel map corresponding to the predetermined pattern, 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.
