Abstract: A human body detection sensor includes: a detection decision unit that decides whether a state is a detection state or a non-detection state of a detection target; a specular reflection decision unit that decides whether or not reflected light that is incident onto a line sensor is specularly-reflected light; and a continuation decision unit that decides whether or not a state in which the detection target exists is ongoing, wherein, when specularly-reflected light is detected while a determination is made indicating the detection state, the detection decision unit keeps the result of a determination indicating the detection state without change if the result of the decision by the continuation decision unit indicates that the state is ongoing and changes the determination to a determination indicating the non-detection state if the result of the decision shows any other states.

Abstract: An automatic water faucet includes: 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 a distance from the imaging unit to the measure-distance target based on image data; 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 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. The threshold setting unit increases the threshold setting in response to the detection unit detecting a detection object.

Abstract: A water spout control device has a target object detector configured to detect a position of a target object as a detection target in a regional image according to an image information of the regional image. The regional image being generated by capturing an imaging target region including a faucet spout. A faucet spout port detector may be configured to detect a position of a faucet spout port of the faucet spout in the regional image. A determiner may be configured to determine whether to discharge water according to the position of the target object detected by the target object detector and the position of the faucet spout port detected by the faucet spout port detector.

Abstract: An automatic water faucet includes a spout pipe; a spout port member having a spout port, the spout port member being housed at a leading end of the spout pipe such that the spout port member can be freely pulled out; and a sensor provided in the vicinity of the spout port for causing water to start being discharged upon detecting an object underneath the spout port. The spout port member is configured to be pulled out from a side behind the sensor in an axial direction of the spout pipe.

Abstract: A person-detecting sensor includes: a range-finding unit that decides whether distance to a detection object falls within a predetermined detection distance range; and a specular reflection decision unit that decides whether reflected light is specularly-reflected light. The specular reflection decision unit performs a threshold determination regarding the count of pixels or the proportion of pixels exhibiting a received-light quantity of a predetermined proportion or greater with respect to the maximum received-light quantity among received-light quantities from the reflected light and decides that the reflected light is specularly-reflected light when the count of the pixels or the proportion of the pixels is a predetermined threshold or less.

Abstract: A detachment sensor detects attachment and detachment of a water discharger to and from a retainer. An object sensor detects presence of an object. A controller causes water discharge triggered by detection of an object by the object sensor while the water discharger is attached to the retainer and suppresses water discharge triggered by detection of an object by the object sensor while the water discharger is detached from the retainer. The controller suppresses water discharge triggered by detection of an object by the object sensor after attachment of the water discharger to the retainer until a non-detection state of an object by the object sensor continues for a predetermined period of time.

Abstract: A person-detecting sensor includes: a range-finding unit that decides whether a distance to a detection object falls within a predetermined detection distance range; a received-light quantity decision unit that decides whether a received-light quantity is equal to or greater than a predetermined received-light quantity threshold; and a continuation decision unit that decides whether a state of the detection object being present is ongoing. In the received-light quantity decision unit, after water discharge is started upon the detection determination unit determining a detection object to be under detection state, for a period during which the continuation decision unit decides the state in which the detection object being present is ongoing, the received-light quantity threshold is set to be lower than prior to when the water discharge is started.
