Camera terminal and imaged area adjusting device

A sensor terminal constituting a detection zone adjusting apparatus that adjusts a detection zone using multiple sensor terminals, the sensor terminal, comprising:

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

An imaging zone adjusting method in a camera terminal constituting an imaging zone adjusting apparatus that adjusts an imaging zone using multiple camera terminals, the camera terminal including a camera that images 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, and a communication unit configured to send and receive hypothetical imaging zone information indicating the hypothetical imaging zone, the imaging zone adjusting method, comprising:

• adjusting 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 and the hypothetical imaging zones of the other camera terminals indicated by the hypothetical imaging zone information received by the communication unit so that a combined zone of the hypothetical imaging zones of the multiple camera terminals completely covers a specific imaging target zone;
• and
• adjusting 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.
