Abstract

In an editing apparatus of audiovisual information including moving picture information, audiovisual information is stored in a hard disk drive or the like, and editing information is stored in a hard disk drive. After retrieve is started, pictures are extracted and displayed among the picture information from the current position to a destination position, and a picture at the retrieve destination is displayed thereafter. Thus, after a situation on the shift of the pictures is displayed during some time, an editor can recognize the completion of retrieve. The retrieve mode includes a constant time retrieve, a constant speed retrieve, and an accelerating and decelerating retrieve. A picture indicating a state under retrieve can be added to the pictures during retrieve.
