Abstract

A method of editing an image with the aid of a computer while watching moving image information displayed on a screen includes a step of selecting still images representing a plurality of video scenes or a plurality of video cuts constituting the moving image information, a step of determining a hierarchical structure among a plurality of scenes and a plurality of cuts represented by still images, a step of designating static images related to an optional hierarchical structure portion in the hierarchical structure, and a step of displaying the hierarchical portion including designated still images on a screen with such an arrangement that shows the hierarchical structure. An apparatus for editing a moving image for editing an image with the aid of a computer while watching moving image information displayed on a screen includes a recording apparatus for recording moving image information, a change point detection segment for comparing adjacent frame images with each other, and recognizing that, when information is changed exceeding a predetermined quantity between adjacent frame images, the adjacent frame images are frame images belonging to different cuts, reduced images obtained from frame images constituting respective cuts and information for identifying the cuts being recorded in the recording apparatus, a control segment for generating information for identifying scene images by putting a plurality of predetermined cuts together as scene images, generating information for identifying a motion picture by collecting a plurality of predetermined scenes as a motion picture, and determining a hierarchical structure among the scenes and cuts represented by said reduced images in accordance with the selection of reduced images representing a plurality of video scenes or a plurality of video cuts constituting moving image information, a designation segment for designating reduced images related to a predetermined hierarchical structure portion in the hierarchical structure, and a display monitor for showing a hierarchical portion including designated reduced images with such an arrangement as to show the hierarchical structure.
