The event detection unit 130 detects, as an event, the acceleration detected by the acceleration information acquisition unit 129 when the driving information acquisition unit 132 is acquiring information indicating that the vehicle is stopped, for example.

[Processing of vehicle recording control device]
Processing of the vehicle recording control device according to the first embodiment will be explained using FIG. 2. FIG. 2 is a flowchart showing an example of the process flow of the vehicle recording control device according to the first embodiment. The flowchart of FIG. 2 is initiated when the vehicle is stopped or parked. Alternatively, it is started when the vehicle recording device 1 operates the parking monitoring function.

The control unit 100 determines whether acceleration equal to or higher than a predetermined value is detected (step S10). Specifically, the event detection unit 130 determines whether or not an acceleration equal to or higher than a predetermined value is detected based on the acceleration information acquired by the acceleration information acquisition unit 129. Acceleration greater than a predetermined value is acceleration given to the vehicle by another vehicle or another person. Then, the process advances to step S11. If it is determined that an acceleration equal to or higher than the predetermined value has been detected (step S10; Yes), the process advances to step S11. On the other hand, if it is determined that acceleration greater than the predetermined value is not detected (step S10; No), the process proceeds to step S16.

If the determination in step S10 is Yes, the control unit 100 determines whether a registered person is present in the vehicle interior or near the vehicle (step S11). Specifically, the person determination unit 125 determines whether a registered person is present in the vehicle interior or near the vehicle based on the first photographic data or the second photographic data. If it is determined that a registered person is present in the vehicle or near the vehicle (step S11; Yes), the process advances to step S12. On the other hand, if it is determined that there is no registered person in the vehicle interior or near the vehicle (step S11; No), the process advances to step S14.

If the determination in step S11 is Yes, the control unit 100 determines whether another vehicle or other person is present (step S12). Specifically, the surrounding situation determination unit 126 determines whether or not there are other vehicles or other people around the vehicle based on the second photographic data. If it is determined that another vehicle or other person is present (step S12; Yes), the process advances to step S13. On the other hand, if it is determined that no other vehicle or person exists (step S12; No), the process advances to step S16.

If the determination in step S12 is Yes, the control unit 100 determines whether the other vehicle or the other person satisfies the event condition (step S13). Specifically, the event detection unit 130 determines whether the event condition is satisfied based on the situation of the other vehicle or the other person. The event detection unit 130 determines that the event condition is satisfied, for example, when there are other vehicles or other people around the vehicle. The event detection unit 130 determines that the event condition is satisfied, for example, when another vehicle or another person is close to the vehicle. The event detection unit 130 determines that the event condition is satisfied, for example, when the positions of other vehicles or other people around the vehicle are changing. If it is determined that the event condition is satisfied (step S13; Yes), the process advances to step S14. On the other hand, if it is determined that the event situation is not satisfied (step S13; No), the process advances to step S16.

If the determination in step S13 is Yes, the control unit 100 determines that an event has occurred based on the acceleration detected in step S10 that is equal to or higher than a predetermined value. In other words, the acceleration detected in step S10 is detected as an event (step S14). Specifically, the event detection unit 130 detects the event as an event if the determination is Yes in step S10, but detects it as an event if the determination is Yes in step S11 and the determination is No in the processing of steps S12 and S13. do not. Then, the process advances to step S15.

The control unit 100 stores the event record data (step S15). Specifically, the recording control unit 123 stores the second photographic data of the period corresponding to the detected event in the recording unit 30. Then, the process advances to step S16. The period corresponding to the detected event is, for example, a period of 60 seconds before and after the time when acceleration of a predetermined value or higher is detected in step S10. Saved as event record data. Further, the photographic data stored as event record data may be second photographic data and first photographic data of a period corresponding to the detected event.

The control unit 100 determines whether event detection has ended (step S16). Specifically, the event detection unit 130 determines that event detection has ended when the operation control unit 127 receives a signal from the operation unit indicating that event detection is to be ended. The end of event detection means, for example, the end of the parking monitoring function. If it is determined that the event detection has ended (step S16; Yes), the process in FIG. 2 ends. If it is determined that event detection has not been completed (step S16; No), the process advances to step S10.

As described above, in the first embodiment, it is determined whether the event condition is satisfied, and only when the event condition is satisfied, the photographed data is saved as event record data. Thereby, the first embodiment can appropriately store photographic data related to an event.

In the first embodiment, acceleration applied by a vehicle owner during vehicle maintenance or the like is not detected as an event, but only acceleration applied due to an accident or the like is detected as an event. In other words, in the first embodiment, even if an acceleration of a predetermined value or more is applied to the vehicle, the photographed data is an event if the acceleration is intentionally generated by the person using the vehicle, such as the owner of the vehicle. Acceleration that occurs unintentionally by the vehicle owner or vehicle user, that is, photographed data that is likely to cause an accident with another vehicle or trouble with another person, is not saved as recorded data, but is recorded as event recording data. Record. This can prevent the storage capacity of the recording unit from being overwhelmed by unnecessary event recording data with a low possibility of an accident.

In the first embodiment, an event is detected and event record data is stored based on first photographic data photographing the interior of the vehicle and second photographic data photographing the surroundings of the vehicle. Thereby, the first embodiment can appropriately store event record data caused by an accident or trouble caused by a third party including another vehicle or another person.

[Second embodiment]
A vehicle storage device according to a second embodiment will be described using FIG. 3. FIG. 3 is a block diagram showing an example of the configuration of a vehicle storage device according to the second embodiment.

As shown in FIG. 3, the vehicle recording device 1A is different from the vehicle recording device 1 shown in FIG.

The motion determination unit 133 determines the motion of the person. The motion determination unit 133 determines the relationship between the acceleration applied to the vehicle and the motion of the person. The motion determination section 133 determines, for example, the relationship between the acceleration of a predetermined value or more acquired by the acceleration information acquisition section 129 and the motion of a pre-registered person existing inside or around the vehicle. Specifically, the motion determination unit 133 determines whether the acceleration acquired by the acceleration information acquisition unit 129 is caused by a motion of a person registered in advance.

The motion determining section 133 determines that when the arms and legs of a registered person move in the vicinity of the vehicle among the motions of a pre-registered person existing inside or around the vehicle, the acceleration information acquisition section 129 determines that the acceleration information acquisition section 129 If acceleration is detected, it is determined that the acceleration and the motion of the registered person are related, in other words, it is determined that the acceleration is caused by the motion of the registered person.

Processing of the vehicle recording control device according to the second embodiment will be explained using FIG. 4. FIG. 4 is a flowchart showing an example of the process flow of the vehicle recording control device.

The processing from step S20 to step S23 shown in FIG. 4 is the same as the processing from step S10 to step S13 shown in FIG. 2, respectively, so the explanation will be omitted.

If the determination in step S23 is Yes, the control unit 100A determines whether the acceleration applied to the vehicle is due to the motion of the registered person (step S24). Specifically, the motion determination unit 133 analyzes the motion of the registered person included in the first photographic data, and determines whether the acceleration applied to the vehicle is caused by the motion of the registered person. If it is determined that the acceleration is caused by the motion of the registered person (step S24; Yes), the process advances to step S27. On the other hand, if it is determined that the acceleration is not caused by the motion of the registered person (step S24; No), the process advances to step S25.

The processing from step S25 to step S27 shown in FIG. 4 is the same as the processing from step S14 to step S16 shown in FIG. 2, respectively, so the explanation will be omitted.

As described above, in the second embodiment, even if another vehicle or another person satisfies the event condition, it is determined whether the acceleration applied to the vehicle is due to the action of the registered person, and the acceleration is registered. Only accelerations that are not caused by human movements are detected as events. In other words, in the second embodiment, only accelerations caused by other persons and other vehicles that are not registered in the vehicle recording device 1A are detected as events. Thereby, photographic data caused by an event can be stored more appropriately.

[Third embodiment]
Next, a third embodiment will be described. The configuration of the vehicle recording device according to the third embodiment is the same configuration as the vehicle recording device 1 shown in FIG. 1, so the description thereof will be omitted.

In the third embodiment, the recording control unit 123 records photographic data in the recording unit 30 as event recording data according to the priority of overwriting. For example, if the acceleration information acquisition unit 129 has not acquired an acceleration of a predetermined value or more, the recording control unit 123 records the photographic data in the recording unit 30 in an overwritable state. For example, when the event detection unit 130 detects an acceleration of a predetermined value or more acquired by the acceleration information acquisition unit 129 as an event, the recording control unit 123 gives priority to overwriting, such as prohibiting overwriting, of the photographed data of the period corresponding to the event. The data is stored in the recording unit 30 as first event record data with a low degree of occurrence. For example, when the event detection unit 130 does not detect an acceleration of a predetermined value or higher acquired by the acceleration information acquisition unit 129 as an event, the recording control unit 123 records the photographic data of the period corresponding to the time point at which the acceleration was acquired as a first event. The event recording data is recorded in the recording unit 30 as second event recording data having a higher overwriting priority than the recording data. In other words, in the third embodiment, when the acceleration information acquisition unit 129 acquires an acceleration of a predetermined value or more, the recording control unit 123 records information about the acceleration information obtained by a third party other than the pre-registered person, such as another vehicle or another person. If the acceleration is caused by an event, the photographic data for the period corresponding to the event is stored in the recording unit 30 as first event record data with a low overwrite priority such as overwrite prohibition. In addition, if the acceleration is caused by a pre-registered person, the shooting data for the period corresponding to the time when the acceleration was acquired will be overwritten with the second event record data that has a higher priority than the first event record data. It is recorded in the recording unit 30 as follows.

The overwrite priority set by the recording control unit 123 is such that, for example, the first event record data is saved as data that is prohibited from being overwritten, and the second event record data is saved as data that will not be overwritten until, for example, the second overwrite. . As another example, the first event record data is saved as data that is prohibited from being overwritten, and the second event record data is saved as data that cannot be overwritten for a period of, for example, two days.

The recording control unit 123 may change the data capacity of the event record data depending on the overwriting priority. The recording control unit 123 may record the second event record data in the recording unit 30 by making the data capacity smaller than the first event record data. For example, when recording the second event record data in the recording unit 30, the recording control unit 123 may record the second event record data with lower image quality than the first event record data, or may record the second event record data with a shorter recording time. good. For example, when recording with reduced image quality, the recording control unit 123 may reduce the frame rate of the second event recording data and record it in the recording unit 30.

[Processing of third embodiment]
The processing of the recording control device according to the third embodiment will be explained using FIG. 5. FIG. 5 is a flowchart showing an example of the processing flow of the recording control device according to the third embodiment.

The processes from step S30 to step S34 and step S37 shown in FIG. 5 are the same as the processes from step S10 to step S34 and step S16 shown in FIG. 2, respectively, so the explanation will be omitted.

After step S34, the control unit 100 stores the first event record data (step S35). Specifically, the recording control unit 123 stores the second photographic data of the period corresponding to the detected event in the recording unit 30 as first event recording data with a low overwriting priority such as overwriting prohibited. Then, the process advances to step S37.

If the determination is No in step S32 and No in step S33, the control unit 100 stores the second event record data (step S36). Specifically, the recording control unit 123 stores the second photographic data of the period corresponding to the period in which acceleration is detected in the recording unit 30 as second event record data having a higher overwriting priority than the first event record data. Record. Then, the process advances to step S37.

As described above, in the third embodiment, in addition to photographic data in which an event has been detected, photographic data in which an event has not been detected is also saved when an acceleration of a predetermined value or higher is detected. Thereby, the third embodiment can more appropriately store photographic data related to an event.

In the third embodiment, photographic data in which an event has been detected is recorded in the recording unit 30 with a lower overwriting priority than photographic data in which an event has not been detected. In other words, in the third embodiment, the event detection unit 130 preferentially overwrites the photographed data for which no event has been detected. Thereby, the third embodiment can more appropriately store photographic data related to an event.

In the third embodiment, the data volume of photographic data that is not detected as an event is reduced and saved. Thereby, it is possible to further prevent the recording capacity of the recording unit 30 from being overwhelmed by photographic data of low importance.
