Abstract
A monitor is arranged on the opposite side of a surgery table to a main doctor so that an assistant is able to view a surgery area directly without being blocked by the monitor. A camera has a working distance of more than or equal to 60 cm and is therefore above a view field for the main doctor to view the monitor, so that the visibility of the monitor is not hindered. The working distance is not more than 100 cm so that the resolution of the camera is not lowered too much.
