Abstract:
To control water discharge without affecting the designability of a water discharge unit.SOLUTION: A water discharge control device 1, on the basis of the image information about a photographed image obtained by capturing an imaging object region 40 including a water discharge unit 10 from the upper side by an imaging unit 20, extracts information about the water discharge unit 10 by a first detection unit 31, a first coordinate extraction unit 33 and a first size extraction unit 35 (first information extraction unit), and extracts information about a hand H by a second detection unit 32, a second coordinate extraction unit 34 and a second size extraction unit 36 (second information extraction unit). A matching detection unit 37 and a ratio operation unit 38 (determination unit) determine whether or not the hand H is in a prescribed region with respect to the water discharge unit 10 on the basis of each extraction information, and determine whether or not the ratio of the size of the hand H to the size of the water discharge unit 10 in the photographed image is within a prescribed range. A control signal output unit 39 (control unit) controls water discharge and water stop of the water discharge unit 10 on the basis of each determination result of the matching detection unit 37 and the ratio operation unit 38.SELECTED DRAWING: Figure 1
