Abstract
An optical communication apparatus includes: a reception unit that receives, from a transmission apparatus which transmits a light signal including predetermined information, the transmitted light signal; a multipath removal unit that recognizes, when detecting a plurality of images having the same optical information in the received light signal, the light signal due to a reflection wave based on at least one of a luminance of the light signal, a size of an image corresponding to the light signal when receiving at the reception unit, and a propagation distance of the light signal and removes the light signal due to the reflection wave; and an control unit that acquires, from the light signal received by the reception unit, information based on the light signal obtained by removing the light signal due to the reflection wave by the multipath removal unit.
