Abstract

Based on the event detected by event detection unit 3, scene definition unit 4 defines the segment from the frame which is one screen of the moving picture corresponding to the event to the end of the next event as the scene The scene information of the defined scene is stored in scene information storage unit 5, and moving picture display unit 9 reads and displays the moving picture stored in moving picture storage unit 2 based on the scene information stored in scene information storage unit 5.

Claims

1. A moving picture collection apparatus, comprising:

an event detection unit for detecting an event of one of a change in a shooting subject, the change in a shooting device, and an operation of a user during shooting with a shooting device; and

a frame number obtainment unit for obtaining a frame number of a frame which is one screen of the moving picture corresponding to the event; and

an event information storage unit for storing event information which corresponds to the event detected by the event detection unit and the frame number;

wherein the event detection unit detects, as the event, one of the change in a position of the shooting device, the change in a direction of the shooting device, the change in a lens condition, an operation of a recording start of a user and an operation of a recording end of the user, and

wherein the event detection unit detects, as the event, an approach of the shooting device toward a preset shooting subject.

2. The moving picture collection apparatus of claim 1, wherein the event information storage unit obtains an image data of a frame in the moving picture corresponding to the event, and obtains the change in the position of the shooting device corresponding to the event, direction of the shooting device and the change of the lens condition corresponding to the event, and stores as the event information.

3. The moving picture collection apparatus of claim 1, wherein the event detection unit detects, as the event, one of an entering, and a coming out of the shooting device to/of a preset shooting area.

4. The moving picture collection apparatus of claim 1, further comprising a shooting device control unit for sending an order to the shooting device to change its direction toward the shooting subject corresponding to the event of approaching of the shooting device toward the preset shooting subject corresponding to the event detected by the event detection unit.

5. The moving picture collection apparatus of claim 4, wherein the shooting device control unit sends an order of one of a recording start and a recording end corresponding to the event of one of entering and coming out of the shooting device to/of the preset shooting area.

6. The moving picture collection apparatus of claim 1, further comprising an event information display unit for displaying the event information, a command input unit for inputting an instruction from a user based on the displayed event information, and a moving picture playback instruction unit for selecting the event based on the instruction input by the command input unit, and specifying the frame number of the frame in the moving picture corresponding to the selected event, and instructing a playback of the moving picture from the frame specified by the frame number.
