Patent ID: 8019227

Claim:
An information transmitting system comprising light emitting apparatuses for modulating information into a temporal luminance change to emit light and an information decoding apparatus for continuously in time picking up an image of the light emitted from the light emitting apparatuses, thereby receiving the light, and for decoding information from the luminance change of the received light, wherein the information decoding apparatus comprises: a storage section which stores plural sets of (i) decoded information and (ii) a light receiving position in a field angle of the picked-up image of the light having the temporal luminance change of light, emitted from the light emitting apparatuses, wherein the decoded information and the light receiving position are associated with each other; a judging section which judges whether or not common information, which is common respectively to at least two light receiving positions corresponding to the light of the light emitting apparatuses, is included in plurality pieces of the decoded information stored in the storage section; and a displaying/outputting section which, when the judging section determines that the common information is included, displays and outputs a portion area including the at least two light receiving positions corresponding to the light of the light emitting apparatuses together with the field angle of the picked-up image in a distinguishable manner from an area including another light receiving position.
