An imaging system includes a body, a first processing circuit provided at the body, a gimbal carried by the body, an image collection circuit carried by the gimbal, a second processing circuit provided at the gimbal, a third processing circuit provided at the body, and a signal transmission line. One end of the signal transmission line is connected to the second processing circuit, and another end of the signal transmission line is connected to the third processing circuit. The second processing circuit is configured to encode a multi-channel first signal output by the image collection circuit to output a second signal. The third processing circuit is configured to receive the second signal through the signal transmission line, decode the second signal to obtain a decoded second signal, and transmit the decoded second signal to the first processing circuit.
