摘要： An information transmission system includes a transmission apparatus and a reception apparatus and uses visible lights as transmission media. The transmission apparatus includes a generating unit and a first replace unit. The generating unit generates a multi-value symbol stream. The first replace unit replaces the multi-value symbol stream generated by the generating unit to a discontinuous symbol stream. The discontinuous symbol stream is a symbol stream without a sequence of identical symbol values. The number of identical symbol values in the sequence is equal to or greater than a predetermined number. The reception apparatus includes an acquiring unit and a second replace unit. The acquiring unit acquires the discontinuous symbol stream. The second replace unit replaces the discontinuous symbol stream acquired by the acquiring unit to the multi-value symbol stream according to a predetermined rule.

摘要： Moving-objects movable in a workspace, each includes an imaging unit with a two-dimensional light receiving surface; and a decoding processing unit. If light received by an imaging surface of the imaging unit is brightness-modulated information, the decoding processing unit decodes the received light to the information. If the information decoded by the decoding processing unit contains spatial position information of moving-objects other than a self-moving-object, the self-moving-object receives the light from light sources, has the decoding processing unit decode the light to acquire pieces of position information of the other moving-objects, thereby acquiring position information of the self-moving-object in the workspace from these pieces of position information.

摘要： A light receiver of a communication apparatus receives light from an LED that emits light based on a light-emission pattern defined by an ID. An ID acquirer specifies the light-emission pattern from light received by the light receiver and acquires the ID. A transceiver transmits the acquired ID to a service server that stores an ID/URL table associating together the ID and a URL of information relating to equipment equipped with the LED, and receives a corresponding URL. An information acquirer acquires the information relating to the equipment based on the URL received by the transceiver.

摘要： A transmission-side information terminal displays a marker whose wavelength changes with time on the basis of a tag ID acquired from a management server. A receiving-side information terminal takes an image to acquire the tag ID, and transmits storage instruction information to a distribution server, the storage instruction information including the tag ID, an area number indicating a position of the receiving-side information terminal and image data acquired by taking an image. The image distribution server stores the tag ID, the area number and the image data in the storage instruction information in association with one another. The transmission-side information terminal transmits query information including the tag ID acquired from the management server and the area number indicating its own position to the image distribution server, thereby acquiring image data associated with the tag ID and the area number from the image distribution server.
