Abstract

PURPOSE:To set up synchronous relation based upon errors and trial by providing this synchronous editing device with an event relation link direct setting means for setting up an event relation link from an optional event up to the start or end event of the time axis of an optional event. CONSTITUTION:When a user forms an event on an optional frame in the time axis of video data by a direct coordinate specifying means 102, an event display means 105 displays the event on the time axis. When the user specifies the setting of the event relation link from the event concerned up to the start or end event of the time axis of an optional object by using the means 102, the event relation link direct setting means 107 directly sets up relation between both events, so that the event relation link is displayed on a tool panel by an event relation link display means 106. Thus, synchronous relation based upon errors and trail can be set up.

The events 207 and 208 displayed on the time axis 205 of the video data are collected by the event display means 1.
Event-related links 211 and 212 are displayed, respectively, indicating that the events 209 and 210 displayed on the time axis of the object 203 are excited by 05. To explain this using an example where you want to hide an object, first play back the video data and search for the scene in which you want the event to occur. When the target scene is played back, the playback speed changing means 109 is used to play back a still image in that scene. The currently played frame 2 is displayed by the currently played frame display means.
14 is displayed. The tool panel in this state is shown at 301 in FIG.

Now, when the user specifies the intersection point 302 between the time axis 205 of the video data and the current playback frame 214 with the pointer 213, the event display means 105 displays an event on the intersection point 302, and the event of the excitation partner is in an undetermined state. Event related link display means 1
06 is displayed. The tool panel at this time is shown in 303.

In the tool panel 303, 304 is an event on the video data time axis, 305 is an event-related link whose excitation destination event is undetermined, and the pointer 213 is used to specify the destination coordinates 306 of the arrow of this event-related link 305. Now, if you move the tip of the arrow to the coordinates 307 of the display end event 210 on the object time axis 206, the coordinates will be acquired by the direct coordinate specifying means, and the event-related link direct setting means will move to the desired excitation destination event. Sent to 109
Event-related link direct setting means 109 GA recognizes the excitation destination of the event-related link from its coordinates and transmits that information to the event-related link display means 106a.As a result, the event-related link 308 is displayed and editing of the synchronization relationship can be completed. As described above, according to this embodiment, the direct coordinate specifying means 102, the video data time axis display means 102, the object time axis display means 103, the event display means 105, and the event-related link display means 1
