Imaging Region Adjustment Device

An imaging region adjusting method for adjusting an imaging region using camera terminals which images virtual imaging regions obtained while changing a position of an imaging region within a specific region in a specific period of time, said imaging region adjusting method comprising:

• an adjusting step of adjusting a position of the virtual imaging region of each camera terminal so that a combined region of the virtual imaging regions of the camera terminals completely covers a specific imaging target region;
• and
• a region dividing step of dividing, into N regions, a region containing virtual imaging regions of N (≧2) camera terminals among the camera terminals and allocating the respective divided regions to the N camera terminals,
• wherein, in said adjusting step, the adjusting is executed regarding the region allocated in said region dividing step as a new virtual imaging region.

A camera terminal constituting an imaging region adjustment device which adjusts an imaging region using camera terminals, said camera terminal comprising:

• a camera which images a virtual imaging region obtained while changing a position of an imaging region within a specific region in a specific period of time;
• a communication unit operable to send and receive virtual imaging region information indicating the virtual imaging region;
• and
• an adjusting unit operable to adjust a position of the virtual imaging region of one's own camera terminal so that a combined region of the virtual imaging regions of said camera terminals completely covers a specific imaging target region, based on the virtual imaging region of one's own camera terminal and virtual imaging regions of the other camera terminals indicated by the virtual imaging region information received by said communication unit,
• wherein said adjusting unit is further operable to divide, into N regions, a region containing the virtual imaging regions of N (≧2) camera terminals among said camera terminals, allocate the respective N divided regions to said N camera terminals, and execute the adjustment of the region allocated to own camera terminal, regarding the allocated region as a new virtual imaging region.

An imaging region adjusting method executed by a camera terminal constituting an imaging region adjustment device which adjusts an imaging region using camera terminals, said imaging region adjusting method comprising:

• an imaging step of imaging virtual imaging regions obtained while changing a position of an imaging region within a specific region in a specific period of time;
• a communication step of sending and receiving virtual imaging region information indicating the virtual imaging region;
• and
• an adjusting step of adjusting a position of the virtual imaging region of one's own camera terminal so that a combined region of the virtual imaging regions of the camera terminals completely covers a specific imaging target region, based on the virtual imaging region of one's own camera terminal and virtual imaging regions of the other camera terminals indicated by the virtual imaging region information received in said communication step,
• wherein, in said adjusting step, a region containing virtual imaging regions of N (≧2) camera terminals among the camera terminals are divided into N regions, the respective divided N regions are allocated to the N camera terminals, and the adjusting is executed, regarding the allocated region as a new virtual imaging region.

• wherein each of said sensor terminals includes:
• a sensor which detects a virtual detecting region obtained while changing a position of a detecting region within a specific region in a specific period of time;
• a communication unit operable to send and receive virtual detecting region information indicating the virtual detecting region;
• and
• an adjusting unit operable to adjust a position of the virtual detecting region of one's own sensor terminal so that a combined region of the virtual detecting regions of said sensor terminals completely covers a specific detecting target region, based on the virtual detecting region of one's own sensor terminal and virtual detecting regions of the other sensor terminals indicated by the virtual detecting region information received by said communication unit,
• wherein said detecting region adjustment device further comprises
• a region dividing unit operable to divide, into N regions, a region containing virtual detecting regions of N (≧2) sensor terminals among said sensor terminals and allocate the respective divided regions to said N sensor terminals, and
• said adjusting unit is operable to execute the adjustment of the region allocated to said sensor terminal by said region dividing unit, regarding the allocated region as a new virtual detecting region.
