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 playback apparatus, comprising:

a moving picture storage unit for storing a plurality of moving picture;

a scene definition unit for defining a segment in the moving picture stored in the moving picture storage unit as a scene;

a scene information storage unit for storing scene information of the scene defined by the scene definition unit;

a typical frame storage unit for storing scene information of the scene defined by the scene definition unit;

a typical frame storage unit for storing a typical frame which represents the scene defined by the scene definition unit;

a typical frame determination unit for selecting the typical frame, which represents the scene, in the scene defined by the scene definition unit, reading the selected typical frame from the moving picture storage unit, and storing in the typical frame storage unit;

a command input unit for inputting an instruction from a user; and

a moving picture display unit for displaying the typical frame stored in the typical frame storage unit based on the instruction input by the command input unit;

wherein the moving picture display unit displays the typical frame from the typical frame storage unit if the frame to be displayed is the typical frame, and displays the closest typical frame before the typical frame to be displayed from the typical frame storage unit if the frame is to be displayed is not the typical frame.

2. The moving picture playback apparatus of claim 1, wherein the moving picture display unit displays the frame to be displayed from the moving picture storage unit if the frame to be displayed is not the typical frame when the instruction input from the command input unit is one of a stop, frame forward, and frame rewind.

3. The moving picture playback apparatus of claim 1, wherein the moving picture display unit displays the typical frame from the typical frame storage unit if the frame to be displayed is the typical frame when the instruction input from the command input unit is one of the stop, frame forward, and frame rewind.
