Abstract:
1. A transmission system comprising: a transmitter: and a receiver configured to receive a signal transmitted by the transmitter; wherein the transmitter comprises: one or a plurality of light sources configured to emit a visible light whose light amount corresponds to a first drive signal; a modulator configured to, according to transmission data to be transmitted from the transmitter to the receiver, modulate a first luminance signal indicative of an amount of the light the light source is configured to emit, to generate a second luminance signal; a first driver configured to generate the first drive signal based on the second luminance signal; a display on which a video depending on a second drive signal using the visible light emitted by the light source; and a second driver configured to generate the second drive signal based on an input video signal, wherein a mean of the second luminance signal during one frame in the input video signal is substantially equal to a value of the first luminance signal in the frame, and wherein the receiver comprises: a light receiver configured to receive the video displayed on the display; and a demodulator configured to demodulate the received video to reproduce the transmission data.
