PROBLEM TO BE SOLVED: To provide a contact detection system that detects both input from an input device and input using a part of a human body, and does not prevent smooth input using the input device.SOLUTION: One or more object detection apparatuses provided on the periphery of a display apparatus to detect contact of an object include light emitting means for emitting light to an object; a device detection apparatus detecting radiation light radiated from a tip to detect contact of an input device to the display apparatus includes imaging means for photographing radiation light radiated from the input device or emission light emitted from the light emitting means; an information processing apparatus includes image acquisition means for acquiring a photographed image photographed by the imaging means, and control means for controlling the light emitting means when the photographed image of the radiation light, of the photographed images including the photographed radiation light and emission light acquired by the image acquisition means, has an area having higher luminance value, so as to control the device detection apparatus to wait for the detection of contact of the input device to the display apparatus.SELECTED DRAWING: Figure 1 |
