摘要 PROBLEM TO BE SOLVED: To correct automatically an error of a stop position caused by a delay in camera control resulting from a transmission delay or the like, by returning time information added to desired video information to a memory section of a camera side. SOLUTION: Upon the receipt of control start information from a room A, a camera control section 30 in a main control section 10 controlling a universal head 12 and a lens 16 in a room B controls the universal head 12 and the lens 16 and sends control information of the time based on control start information from a control side. A time generating section 42 samples timewise control information from the camera control section 30 and sends the time information to a CODEC section 18. Furthermore, an information storage section 44 of a memory section 40 stores position information timewise sampled. Position information at the same time stored in an information storage section 44 based on the time information added to control stop information from the control side is extracted as correction information and given to the camera control section 30.
