Abstract

A method and an apparatus for using the trajectory of an object to access video contents, for example, to specify and display a specific video image scene. Such a video contents access method comprises the steps of: extracting objects from video contents; displaying movements of the objects as trajectories on a specific projection screen; specifying locations on the trajectories; and accessing a desired scene of the video contents. An apparatus is so designed that it performs the above method.
