Abstract

A wearable camera includes: a storage section that stores therein video data of captured moving image; and a controller that adds a bookmark signal to the video data when an event included in the video data is detected, in which the bookmark signal indicates a location at which playback of the video data starts when the video data is played back.

First claim

The invention claimed is:

1. A wearable camera, comprising:
a camera that initiates capturing of a moving image;
a memory that stores therein a video data file of the moving image; and
a controller that automatically adds a bookmark signal to the video data file each time a predetermined event is detected after initiating the capturing of the moving image by the camera, wherein
the controller is configured to add a plurality of bookmark signals to the video data file, each of the plurality of bookmark signals corresponding to one of a plurality of event types,
the plurality of event types including at least a special sound event type and an action event type,
each of the plurality of bookmark signals indicates a location at which playback of a corresponding portion of the video data file starts, and
the captured moving image is continuously recorded while the plurality of bookmark signals is added to the video data file.

2. The wearable camera according to claim 1 , wherein the controller includes, in the bookmark signal, time at which the predetermined event is detected, a place, and a classification indicating an event type.

3. The wearable camera according to claim 1 , wherein the controller detects the predetermined event from an action of a user wearing the wearable camera, living body information of the user, or a sound around the wearable camera.

4. The wearable camera according to claim 3 , wherein the action of the user comprises any one of a dash of the user, a fall of the user, or a fight of the user with another person.

5. The wearable camera according to claim 3 , wherein the sound comprises either one of a gunshot or an explosion sound.

6. The wearable camera according to claim 1 , wherein the controller adds the bookmark signal to the video data file when at least one of a person, a vehicle, an edged tool, a gun, or a crowd is detected.

7. The wearable camera according to claim 1 , wherein, when a face is included in the video data file the controller includes location information indicating a location of the face on an image in the bookmark signal.

8. The wearable camera according to claim 1 , wherein, when a number plate is included in the video data file, the controller includes location information indicating a location of the number plate of a vehicle on an image in the bookmark signal.

9. A video playback system, comprising:
a wearable camera that initiates capturing of a moving image; and
a display apparatus that plays back a video data file of a moving image acquired by the wearable camera, wherein:
the wearable camera, comprises:
a memory that stores therein the video data file of the captured moving image; and
a controller that automatically adds a bookmark signal to the video data file each time a predetermined event is detected after initiating the capturing of the moving image by the camera, wherein

the controller is configured to add a plurality of bookmark signals to the video data file, each of the plurality of bookmark signals corresponding to one of a plurality of event types,
the plurality of event types including at least a special sound event type and an action event type,
each of the plurality of bookmark signal indicates a location at which playback of a corresponding portion of the video data file starts; and
the display apparatus starts playback of the video data file from a location on the video data file indicated by a corresponding bookmark signal among the plurality of bookmark signals,
wherein
the captured moving image is continuously recorded while the plurality of bookmark signals is added to the video data file.

10. The video playback system according to claim 9 , wherein:
the display apparatus displays a plurality of bookmarks corresponding to the plurality of bookmark signals on a list, and starts playback of a portion of the video data file from a location indicated by a bookmark signal among the plurality of bookmark signals that corresponds to a bookmark selected among the plurality of bookmarks displayed.

11. The video playback system according to claim 9 , wherein the display apparatus simultaneously displays a list of the plurality of bookmarks and a video image of the video data file.

12. A video playback method for a video playback system including a wearable camera and a display apparatus that plays back a video data file of a moving image acquired by the wearable camera,
the video playback method comprising:
initiating, by the wearable camera, capturing of a moving image;
storing, by the wearable camera, a video data file of the captured moving image;
automatically adding, by the wearable camera, a bookmark signal to the video data file each time a predetermined event is detected after initiating the capturing of the moving image by the wearable camera, the bookmark signal indicating a location at which playback of the video data file starts, when the video data file is played back; and
starting, by the display apparatus, playback of a portion of the video data file from a location on the video data file indicated by the bookmark signal,
wherein
a plurality of bookmark signals is added to the video data file, each of the plurality of bookmark signals corresponding to one of a plurality of event types,
the plurality of event types including at least a special sound event type and an action event type,
the captured moving image is continuously recorded while the plurality of bookmark signals is added to the video data file.

13. The wearable camera according to claim 1 , further comprising a sensor that detects a movement.

14. The wearable camera according to claim 1 , further comprising a microphone that detects a sound.

15. The wearable camera according to claim 1 , wherein the bookmark signal automatically indicates an event type for the event detected.
