An imaging device includes a camera unit and a control unit. A first power source voltage is transferred from the control unit to the camera unit by a power source line and is input into the camera unit as a second power source voltage. The camera unit is configured to output a video signal, a reference signal having a reference voltage, and a voltage signal in accordance with the second power source voltage to a video signal line. The control unit is configured to measure a voltage value of each of the reference signal and the voltage signal. The control unit is configured to calculate a control value of the first power source voltage by using the measured voltage value.

An image processing apparatus according to a first aspect of the present invention acquires a first image and a second image in a first image acquisition mode, or a second image acquisition mode in which a second image acquisition ratio is higher than in the first image acquisition mode, on the basis of a detection result of a specific target (whether or not a specific target has been detected, what type of specific target). For example, in accordance with whether or not a specific target has been detected and the type of specific target, the first image and the second image can be acquired in the first image acquisition mode in a case where the necessity for acquiring the second image is low, whereas the first image and the second image can be acquired in the second image acquisition mode, in which the second image acquisition ratio is high, in a case where the necessity for acquiring the second image is high.
