Abstract: A receiving method includes: setting a first exposure time for at least one exposure line of exposure lines in an image sensor, setting a second exposure time for a remainder of the exposure lines in the image sensor, and causing the image sensor to capture an image of a light transmitter, to obtain a normal image from the at least one exposure line with the first exposure time, and to obtain a bright line image from the remainder of the exposure lines with the second exposure time. The second exposure time is shorter than the first exposure time. The bright line image includes a plurality of bright lines, each of which corresponds to a different one of the remainder of the exposure lines in the image sensor.

Abstract: A computer-implemented method is provided, in which a plurality of luminance change frequencies of a light emitter is determined by coding one of a plurality of transmission information sources. The light emitter transmits a transmission information source by a change in luminance according to each of the plurality of luminance change frequencies. A signal, which controls the change in luminance of the light emitter according to each of the plurality of luminance change frequencies, is output to the light emitter. The plurality of luminance change frequencies include a first frequency and a second frequency. A signal of the first frequency and a signal of the second frequency respectively cause the light emitter to change in luminance according to the first frequency during a first time period and to change in luminance according to the second frequency during a second time period after the first time period has elapsed.
