Provided is a transmission/reception system that can implement miniaturization and a reduced number of wires for transmitting a signal between a sensor device and a reception device. The sensor device includes a data transmitting unit configured to transmit imaging data synchronized with a first clock signal to the reception device through a first signal transmission path, a clock signal transmitting unit configured to transmit a second clock signal with a lower frequency than the first clock signal to the reception device through a second signal transmission path, and a control signal communicating unit configured to communicate a control signal necessary for control of the first clock signal with the reception device through the second signal transmission path. The reception device includes a signal generating unit configured to generate the control signal on the basis of a comparison result of a comparison between a reference clock signal and any one of the second clock signal based on the first clock signal and the second clock signal transmitted from the sensor device through the second signal transmission path, and a control signal communicating unit configured to communicate the control signal with the sensor device through the second signal transmission path.
