Abstract
According to one embodiment, a transmission system includes a transmitter, and a receiver. The transmitter includes one or a plurality of light sources, a modulator, a first driver, a display, and a second driver. The one or a plurality of light sources is configured to emit a visible light whose light amount corresponds to a first drive signal. The modulator is 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. The first driver is configured to generate the first drive signal based on the second luminance signal. 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.
