6 . The tracking support apparatus according to claim 1 , wherein the tracker selecting section is configured to select the takeover tracker instructed to track the tracking target, using the position information of the plurality of terminals and the calculated position of the tracking target, if the interval time has passed after selecting the selected tracker.
7 . The tracking support apparatus according to claim 1 , wherein the interval time is randomly determined if the selected tracker is selected.
8 . The tracking support apparatus according to claim 1 , wherein the interval time is determined to be a predetermined interval plus a randomly determined time interval if the selected tracker is selected.
9 . The tracking support apparatus according to claim 1 , wherein the interval time is determined using an attribute of the tracking target.
10 . The tracking support apparatus according to claim 1 , wherein the interval time is determined using a situation in a tracking area.
11 . The tracking support apparatus according to claim 10 , wherein the situation relates to at least one of a time zone, a climate condition or a congestion degree.
12 . The tracking support apparatus according to claim 1 , wherein the information transmitting section is configured to transmit information of a distance between the tracking target and a terminal of the selected tracker during tracking of the tracking target to the terminal of the selected tracker.
13 . The tracking support apparatus according to claim 1 , further comprising a receiver configured to receive position information of a plurality of terminals, each one of the plurality of terminals being carried by a tracker.
14 . The tracking support apparatus according to claim 13 , wherein the receiver is configured to:
receive, from the terminal, a notification of a monitoring failure; and
receive, from the terminal, a notification that the tracker requests takeover of the tracking of the tracking target to a new tracker, independently from notification of the monitoring failure.
15 . A non-transitory computer readable medium storing a program which causes a computer configuring a tracking support apparatus that is connected with a plurality of cameras arranged in a predetermined monitoring area to transmit video images imaged by the plurality of cameras, and is configured to transmit an instruction to a tracker carrying a terminal using information received from the plurality of cameras and terminals respectively carried by a plurality of trackers, to execute:
processing of calculating a position of a tracking target using video images received from the plurality of cameras;
processing of selecting a tracker tracking the tracking target, using position information of the terminal received from the terminal and the calculated position of the tracking target; and
processing of transmitting information of an instruction to track the tracking target to a takeover terminal of a takeover tracker other than the selected tracker if an interval time has passed after selecting the selected tracker,
wherein the processing of selecting a tracker includes:
selecting the takeover tracker using inconspicuousness of the takeover tracker in a tracking area.
16 . The medium according to claim 15 , wherein the processing of selecting a tracker selects the takeover tracker different from the selected tracker in at least one of clothes or sexuality.
17 . The medium according to claim 15 , wherein the processing of selecting a tracker selects the takeover tracker using a moving speed of the tracking target.
18 . The medium according to claim 15 , wherein the processing of selecting a tracker selects the takeover tracker, using at least one of outer appearance, a skill and status information of the selected tracker and the takeover tracker.
19 . A tracking support method by a tracking support apparatus that is connected with a plurality of cameras arranged in a predetermined monitoring area to transmit video images imaged by the plurality of cameras, and is configured to transmit an instruction to a tracker carrying a terminal using information received from the plurality of cameras and terminals respectively carried by a plurality of trackers, the method comprising:
calculating a position of a tracking target using video images received from the plurality of cameras;
selecting a tracker instructed to track the tracking target using position information of a terminal received from the terminal and the calculated position of the tracking target; and
transmitting information of instruction to track the tracking target to a takeover terminal of a takeover tracker other than the selected tracker if an interval time has passed after selecting the selected tracker,
wherein the selecting a tracker includes:
selecting the takeover tracker using inconspicuousness of the takeover tracker in a tracking area.
