Abstract

An information processing apparatus comprising: a first recording controlling element for recording moving images; a first detecting element for detecting scene changes in the moving images recorded by the first recording controlling element; a second recording controlling element which, if scene changes are detected from the moving images by the first detecting element, then records still images corresponding to the detected scene changes together with time stamps pertaining to the recorded still images; a third recording controlling element which, if no still image is recorded by the second recording controlling element over a predetermined time period, then records still images at predetermined intervals based on the moving images together with time stamps pertaining to the recorded still images; a first playback controlling element for playing back the moving images recorded by the first recording controlling element; and a second playback controlling element for playing back the recorded still images in a display window at relative distances to one another proportional to differentials between the time stamps.
