The present invention relates to an information processing apparatus in which providing various information is made possible with a simple configuration. Light beacons 2-1 to 2-5 are arranged at predetermined positions in an area 1 and generate their respective identification numbers as optical signals. In a detection section 5, a video camera 4 within the area 1 receives an optical signal from each of the light beacons and detects the position of each light beacon and its own position based on the principle of triangulation. In an image captured by the video camera 4, information corresponding to the detected identification number is displayed. The present invention is applicable to the light beacons, and the detection section for detecting the positions of the light beacons and which is included in the video camera.
