Wearable camera system, and video recording control method for wearable camera system

1. A wearable camera system comprising:

a wearable camera that can be mounted on a user;

an in-car recorder in a vehicle in which the user rides; and

an in-car camera in the vehicle,

wherein the in-car camera includes a first imaging unit that captures video,

wherein the in-car recorder includes:

a first communicator that performs communication with the wearable camera; and

a first recorder that records first video data captured by the in-car camera,

wherein the wearable camera includes:

a second imaging unit that captures video;

a second communicator that performs communication with the in-car recorder;

a second recorder that records second video data captured by the wearable camera; and

a data storage that stores video recording starting factor information linked with the second video data, the video recording starting factor information being information indicating the video recording of second video data by the second recorder of the wearable camera started in response to receiving from the in-car recorder video recording starting information including information indicating that the first recorder has started video recording of an incident attended by the user of the wearable camera, the stored video recording starting factor information capable of indicating to a user of the recorded second video data that the recording of the second video data by the second recorder of the wearable camera started in response to receiving from the in-car recorder the video recording starting information indicating that the first recorder has started video recording of an incident attended by the user of the wearable camera, the user of the camera being a police officer or a security guard,

wherein the in-car recorder causes the first recorder to start recording of the first video data and the in-car recorder transmits the video recording starting information including information indicating that the first recorder has started video recording to the wearable camera via the first communicator, and

wherein the wearable camera causes the second recorder to start video recording in response to reception of the video recording starting information.

2. The wearable camera system of claim 1 ,

wherein the in-car recorder causes the first recorder to stop recording of the first video data and also transmits video recording stopping information including information indicating that the first recorder has stopped video recording to the wearable camera via the first communicator, and

wherein the wearable camera causes the second recorder to stop video recording in response to reception of the video recording stopping information.

3. The wearable camera system of claim 1 , wherein the wearable camera further comprises:

a display, which in operation, displays information indicating the wearable camera is recording second video data in response to the wearable camera receiving the video recording starting information from the in-car recorder.

4. The wearable camera system of claim 1 , further comprising at least one additional wearable camera that can be mounted on a user and the first communicator performs communication with the at least one additional wearable camera.

5. The wearable camera system of claim 1 , wherein the video recording starting factor information further includes information that the video recording of the second video data has been started by operating a switch of the wearable camera.

6. The wearable camera system of claim 1 wherein the data storage further stores meta information that includes at least video time information, car identification information or user of the wearable camera identification information.

7. The wearable camera system of claim 1 , wherein the user of the recorded second video data is a user responsible for investigating an incident.

8. A video recording control method for a wearable camera system including a wearable camera that can be mounted on a user; an in-car recorder that is in a vehicle in which the user rides; and an in-car camera which is in the vehicle, the method comprising:

causing the in-car camera to capture video;

causing the in-car recorder to record first video data captured by the in-car camera;

when the in-car recorder starts recording the first video data, causing the in-car recorder to transmit to the wearable camera video recording starting information including information indicating that video recording by the in-car recorder of an incident attended by the user of the wearable camera has been started, the user of the camera being a police officer or a security guard;

causing the wearable camera to start recording second video data in response to reception of the video recording starting information; and

storing in a data storage of the wearable camera video recording starting factor information linked with the second video data, the video recording starting factor information being information indicating recording second video data by the wearable camera started in response to receiving from the in-car recorder video recording starting information including information indicating video recording by the in-car recorder of an incident attended by the user of the wearable camera has been started, the stored video recording starting factor information capable of indicating to a user of the recorded second video data that recording the second video data by the second recorder of the wearable camera started in response to receiving from the in-car recorder the video recording starting information including information indicating that the first recorder has started video recording of an incident attended by the user of the wearable camera.

9. The method of claim 8 , further comprising displaying via the wearable camera information indicating the wearable camera is recording second video data in response to the wearable camera receiving the video recording starting information from the in-car recorder.

10. The method of claim 8 , further comprising the first communicator performing communication with at least one additional wearable camera.

11. The method of claim 8 wherein the video recording starting factor information further includes information that the video recording of the second video data has been started by operating a switch of the wearable camera.

12. The method of claim 8 , further comprising storing in the data storage, meta information that includes at least video time information, car identification information or user of the wearable camera identification information.

13. The method of claim 8 , wherein the user of the recorded second video data is a user responsible for investigating an incident.
