Abstract
According to one exemplary embodiment, a light communication system comprises a transmitting apparatus and a receiving apparatus. The transmitting apparatus generates one or more patterns of light to decide at least one reference area, and transmits signals by emitting light in the at least one reference area decided by the one or more patterns. The receiving apparatus takes measurements fewer than a total amount of pixels over a sensed image to detect the one or more patterns of light, and decides at least one ROI according to one or more detected one or more patterns; then takes all signals of light in the at least one ROI for processing of the light communication, and takes measurements fewer than a total amount of pixels over at least one tracking area for tracking the one or more patterns of light emitted by the transmitting apparatus.
