According to one embodiment, a transmission system includes a transmitter and a receiver. The transmitter includes a modulator configured to modulate transmission data at a chip rate to generate a modulation signal, and one or a plurality of light sources configured to emit visible light according to the modulation signal. The receiver includes a light receiver having one or more lines of light receiving elements to receive light in a first range including the visible light; and a demodulator configured to demodulate image data generated according to the light received by the light receiver to generate reception data corresponding to the transmission data. A following equation is satisfied ff<fm where fm is the chip rate, and ff is a frame rate of the light receiver.
