Abstract: An imaging device includes a camera unit and a control unit. The camera unit includes an image sensor. The control unit includes a voltage measurement circuit and a voltage adjustment circuit. A first power source voltage is transferred from the control unit to the camera unit by a power source line and is input to the camera unit as a second power source voltage. A video signal or the second power source voltage is output to a video signal line. The voltage measurement circuit is configured to measure a voltage value of the second power source voltage. The voltage adjustment circuit is configured to adjust a value of the first power source voltage based on the value of the second power source voltage.
