Abstract
Official abstract text for this publication.
In a light communication system, a data embedding unit arranged between a transmitter-side communication data processing unit and a light emitting device driver embeds a communication processed data at a spatial domain of an original image according to a modulation scheme, and gets multiple RGB values for a communication data embedded image. A receiving apparatus detects a transmitter-side communication data embedded image, generates a receiver-side communication data embedded image, compensate a deformation of the receiver-side communication data embedded image, outputs a warped communication data embedded image, and extracts a communication processed data from the warped communication data embedded image.
