Claim:
1. An automatic water faucet comprising: a water faucet; an imaging unit provided in a water discharge port of the water faucet and that images light reflected from a measure-distance target; a distance measurement unit that measures distance from the imaging unit to the measure-distance target, based on image data captured by the imaging unit; a threshold setting unit that sets a threshold for distance; a detection unit that detects the measure-distance target as a detection object if the distance that the distance measurement unit measures is shorter than the threshold set by the threshold setting unit; and a water supply control unit that causes the water faucet to discharge water in response to the detection unit detecting a detection object, and causes the water faucet to stop supplying water in response to the detection unit not detecting a detection object; wherein the threshold setting unit increases the threshold setting in response to the detection unit detecting a detection object.
