1. An imaging device connected to a control unit by both a power source line that transfers a first power source voltage and a video signal line that transfers a video signal, the first power source voltage transferred from the control unit by the power source line being input to the imaging device as a second power source voltage, the imaging device comprising:
an image sensor configured to generate the video signal by using the second power source voltage;
a voltage generation circuit configured to generate a first voltage by using the second power source voltage in a first period and generate a second voltage different from the first voltage by using the second power source voltage in a second period different from the first period;
a reference voltage generation circuit configured to generate a reference voltage; and
an output circuit configured to output a first signal indicating the first voltage and the reference voltage to the video signal line and output a second signal indicating the second voltage and the reference voltage to the video signal line, and
wherein an amount of current consumption in the imaging device in the first period is less than an amount of current consumption in the imaging device in the second period.
