the second period is set to be a predetermined period of time, set in accordance with a state of a driver of the vehicle, or set in accordance with a condition at a time of driving of the vehicle,
the capture-data processing unit is further configured to generate, as the event record data, at least the capture data corresponding to the first period including a point in time of occurrence of the event, from the capture data recorded by the loop-recording.
2. The vehicular recording control device according to claim 1 , wherein
the capture-data acquisition unit further acquires third capture data captured by a second capturing unit that captures a range including a driver of the vehicle, and
the recording control unit saves, as the event record data, the third capture data captured by the second capturing unit and fourth capture data of the capture data captured by the first capturing unit both at least corresponding to a third period from the detection of the event by the event detection unit until the detection of the stop of the vehicle by the stop detection unit.
3. The vehicular recording control device according to claim 2 , wherein the recording control unit saves the first capture data corresponding to the first period, and the third capture data and the fourth capture data corresponding to the third period, as continuous event record data.
4. The vehicular recording control device according to claim 1 , further comprising a reproduction control unit, wherein, in the case where no stop of the vehicle is detected by the stop detection unit in the second period after the detection of the event, the reproduction control unit reproduces the event record data based on the capture data captured by the first capturing unit, in response to the stop of the vehicle after the second period elapses.
5. The vehicular recording control device according to claim 1 , further comprising a reproduction control unit, wherein, in the case where no stop of the vehicle is detected by the stop detection unit in the second period after the detection of the event, the reproduction control unit reproduces the event record data based on the first capture data of the capture data corresponding to the first period, in response to the stop of the vehicle after the second period elapses.
6. A vehicular capturing apparatus comprising:
the vehicular recording control device according to claim 1 ;
a first capturing unit configured to capture a vicinity of a vehicle; and
a display unit configured to display capture data captured by the first capturing unit.
7. A vehicular recording control method comprising:
a capture-data acquisition step of acquiring capture data captured by a first capturing unit that captures a vicinity of a vehicle;
an event detection step of detecting an event to the vehicle;
a stop detection step of detecting a stop of the vehicle after the event is detected in the event detection step;
a recording control step of recording the capture data as overwriting-allowed capture data by loop-recording in which old capture data is overwritten with new capture data and recorded, saving, in a case where the event is detected in the event detection step, as no-overwriting-allowed event record data, at least first capture data of the capture data corresponding to a first period resulting from the detection of the event, and saving, in a case where no stop of the vehicle is detected in the stop detection step in a second period after the detection of the event, as the event record data, second capture data of the capture data corresponding to a period until the stop of the vehicle is detected in the stop detection step, in addition to the first capture data corresponding to the first period; and
a generating step of generating the capture data of a certain period as a file from the capture data recorded by the loop-recording, wherein
the second period is set to be a predetermined period of time, set in accordance with a state of a driver of the vehicle, or set in accordance with a condition at a time of driving of the vehicle,
the generating further comprises generating, as the event record data, at least the capture data corresponding to the first period including a point in time of occurrence of the event, from the capture data recorded by the loop-recording.
8. A non-transitory computer readable recording medium storing therein a program for causing a computer that operates as a vehicular recording control device, to perform:
a capture-data acquisition step of acquiring capture data captured by a first capturing unit that captures a vicinity of a vehicle;
an event detection step of detecting an event to the vehicle;
a stop detection step of detecting a stop of the vehicle after the event is detected in the event detection step;
