Information processing device, mobile terminal, user terminal and information processing method

A mobile terminal comprising:

• a position obtainer configured to continuously obtain a terminal positional information for identifying a latest position of a mobile terminal;
• an image capturer configured to capture an image;
• a mobile receiver configured to receive an inquiry including a route identification information;
• a mobile determination unit configured to determine whether or not the latest position included in the terminal positional information obtained by the position obtainer satisfies a route condition which is a condition corresponding to a positional information identifying at least a part of the route identified by the route identification information from the terminal positional information paired with a latest time of each of the one or more mobile terminals in the terminal management table;
• and
• a mobile transmitter configured to transmit a latest image in real time when the mobile determination unit determines that the route condition is satisfied.

An information processing method implemented by a position receiver, an inquiry receiver, a terminal manager configured to continuously accumulate a terminal information received by the position receiver including a terminal positional information for identifying a latest position of each of one or more mobile terminals at each point of time from each of the one or more mobile terminals, a terminal determination unit, an obtainer and a transmitter, the method comprising:

• an inquiry receiving step of receiving, by the inquiry receiver, an inquiry including a route identification information for identifying a route from a user terminal;
• a position receiving step of receiving, by the position receiver, the terminal positional information from each of the one or more mobile terminals;
• a terminal determination process of determining, by the terminal determination unit, the one or more mobile terminals having the latest position located in at least a part of the route identified by the route identification information by referring to the terminal positional information accumulated in the terminal manager;
• an obtaining step of obtaining, by the obtainer, a first image corresponding to a first positional information for identifying a first partial route in the route identified by the route identification information from each of the one or more mobile terminals and obtain a second image corresponding to a second positional information for identifying a second partial route which is beyond the first partial route in the route identified by the route identification information from each of the one or more mobile terminals, the first image and the second image being captured by the one or more mobile terminals determined by the terminal determination unit;
• and
• a transmitting step of transmitting, by the transmitter, the first image and the second image, which are a latest image captured in real time, to the user terminal.

An information processing method implemented by a position obtainer, an image capturer, a mobile receiver, a mobile determination unit and a transmitter, the method comprising:

• a position obtaining step of continuously obtaining, by the position obtainer, a positional information for identifying a latest position of a mobile terminal;
• an image capturing step of capturing, by the image capturer, an image;
• a movement receiving step of receiving, by the mobile receiver, an inquiry including a route identification information;
• a movement determination step of determining, by the mobile determination unit, whether or not the latest position included in the positional information obtained in the position obtaining step satisfies a route condition which is a condition corresponding to the positional information identifying at least a part of the route identified by the route identification information from the terminal positional information paired with a latest time of each of the one or more mobile terminals in the terminal management table;
• and
• a transmitting step of transmitting, by the transmitter, a latest image in real time when the mobile determination unit determines that the route condition is satisfied in the movement determination step.
