PURPOSE: A power supply method of a vehicle antenna equipped with a camera and an image transmitting and controlling device are provided to increase efficiency by using a single camera instead of two cameras. CONSTITUTION: A power supply method(400) of a vehicle antenna equipped with a camera comprises a bias tee circuit(402), an image signal distribution unit(404), and an image switch unit(406). The bias tee circuit amplifies RF(Radio Frequency) transferred from an antenna and outputs RF signals to an image display unit(420). The image signal distribution unit transfers image signals from the camera to an image recorder. The image switch unit transfers or blocks the signals transferred from the image signal distribution unit.
