Abstract
An imaging system according to the present disclosure has a camera unit and a control unit that are connected via a transmission cable having a power signal line and a video signal line. The camera unit includes an imaging element and a selector circuit. The control unit includes a supply voltage control circuit, a feedback value measurement circuit, and an arithmetic circuit that calculates a resistance value R3 related to a resistance value R1 of the video signal line and a resistance value R2 of the power signal line from the supply voltage Vctrl, the feedback voltage Vfb and the feedback current Ifb, and calculates a drive voltage Vcis based on the resistance value R2, the supply current Ictrl, and the supply voltage Vctrl.
