DETAILED DESCRIPTION OF PREFERRED EMBODIMENT Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.
FIG.
1 is a flow chart for developing the database used in a video story browser.
Generally, such a data is formed by setting a plurality of relations between objects and a places in a video story such as a movie or a drama.
As shown in FIG.
1, characters and places necessary to develop events in a story are set as main objects and main places, respectively (step 101).
Subordinate classes to main objects and main places may also be defined.
For example, if the main place is set to a "hospital," scenes may be subdivided as subordinate classes into a corridor, a ward, a surgery room, a lobby, and a hospital garden.
However, if representing the main place simply as a "hospital" would better represent the overall outline of the video story, the subordinate classes are combined to form simply one main place, namely the "hospital.
" After setting the main objects and main places, relationships of the main objects to the main places are set (step 102).
For example, if character A, character B, and character C are set as the main objects; and if a hospital, an indoor, and an outdoor are set as the main place, the relations of the objects and places may be set as follows: places where character A appears are the hospitals and the indoor; places where character B appears are the indoor and the outdoor; and a place where character C appears is the outdoor.
The set relationships reflect the sections of the video story in which objects actually appear in the video story.
Accordingly, the sections in which objects appear with respect to places are defined and indexed using the set relationships.
A section may signify a frame in which an object actually appears or may signify an interval of frames in which an object generally appears.
For example, characters A and B may alternately appear in a section where characters A and B are carrying on a conversation
