Abstract
According to one embodiment, a visible-light communication apparatus includes an image input unit, a calculation unit, a preamble detection unit, a bit train detection unit, and a reception unit. The image input unit is configured to input image data generated by photographing a source of visible light carrying data. The calculation unit is configured to generate, from the image data, luminance data about an image at a designated position. The preamble detection unit is configured to detect a preamble at the head of the data, on the basis of the luminance data. The bit train detection unit is configured to detect the data bit train from the image data, in accordance with the preamble. The reception unit is configured to reproduce the data from the data bit train.
