Patent ID: 7677816

Claim:
A camera terminal constituting an imaging zone adjusting apparatus that adjusts an imaging zone using multiple camera terminals, comprising: a camera configured to image a hypothetical imaging zone that is a hypothetical imaging zone including a sum of imaging zones obtained by changing a rotation angle of said camera or a position of said camera within a specific zone in a specific period of time; an adjusting unit configured to adjust the position of the hypothetical imaging zone by controlling said camera; and a communication unit configured to send and receive hypothetical imaging zone information indicating the hypothetical imaging zone, wherein said adjusting unit is configured to adjust the position of the hypothetical imaging zone to which the camera terminal belongs based on the hypothetical imaging zone to which the camera terminal belongs provided with said adjusting unit and hypothetical imaging zones of the other camera terminals indicated by the hypothetical imaging zone information received by said communication unit so that a combined zone of the hypothetical imaging zones of said multiple camera terminals completely covers a specific imaging target zone, and said adjusting unit is configured to adjust the position of the hypothetical imaging zone to which the camera terminal belongs so that the overlapping zone quantity that is the quantity of a zone where the hypothetical imaging zone to which the camera terminal belongs and a hypothetical imaging zone adjacent to said hypothetical imaging zone overlap converges on a target quantity that is a fixed quantity larger than 0.
