PHOTOGRAPHING SYSTEM FOR TRANSMITTING VIDEO SIGNALS, SUPPLYING POWER, AND CONTROLLING IMAGE PICK-UP DEVICES USING SINGLE LINE

摘要

PURPOSE: A photographing system capable of transmitting video signals, supplying power and controlling image pick-up devices using a single line is provided to reduce line installation cost by providing power to each image pick-up device, transmitting an image captured by each image pick-up device, and delivering a control signal of each image pick-up device using a single cable line. CONSTITUTION: A photographing system includes an image pick-up device(400), a display, and an image pick-up controller(200). The image pick-up device captures an image of an object and outputs a video signal corresponding to the captured image. The display receives the video signal and displays an image corresponding to the video signal. The image pick-up device controller transmits control signals for setting an environment and functions of the image pick-up device to the image pick-up device. The video signal and the control signals are transmitted through a single line.
