INFORMATION PROCESSING APPARATUS AD METHOD, RECORDING MEDIUM, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To enhance communication accuracy in data communication utilizing an optical beacon and an ID recognition camera.

SOLUTION: A light receiving section 141 receives an optical signal emitted from a transmitter for emitting light in a prescribed blinking pattern on the basis of Manchester-encoded data. A storage section 161 stores the optical signal received by the light receiving section 141 in a frequency being N times the prescribed blinking pattern and in the units of frames. A comparison section 162 calculates the information of the amount of received light for a plurality of frames by each of N frames among the information denoting the amount of received light between the frames stored in the storage section 161 in a prescribed form, and compares the arithmetic result with a prescribed threshold. An ID decode processing section 144 decodes the data subjected to Manchester encoding on the basis of the result of the comparison.
