US 2006/0222337 A1 · Digest reproducing apparatus and digest reproducing apparatus control method

Abstract

A digest reproducing apparatus which creates and shows a digest which gives an overview of a whole motion video content regardless of the number of scenes included in an original content. To achieve the above technique, for example, we need to record data on plural still images obtained by encoding plural consecutive still images in time order, detect a scene change in a motion video obtained by reproducing the still image data in time order, calculate an index value indicating the significance level of each still image in the motion video from the still image data, rank scenes in the motion video based on index values indicating the significance levels of still images, and reproduces digest still images included in a specified number of scenes selected according to the ranking.

Dependent claims

A digest reproducing apparatus comprising:

a data recording part that records data, as motion video data, on a plurality of still images obtained by encoding a plurality of consecutive still images in time order;
a scene change detecting part that detects a scene change in a motion video obtained by reproducing the still image data in time order, based on the still image data;
a significance level calculating part that calculates an index value indicating the significance level of each still image in the motion video from the still image data;
a scene ranking part that ranks scenes in the motion video based on index values indicating the significance levels of still images included in each scene of the motion video;
and
a digest reproducing part that reproduces as a digest, in time order, still images included in a specified number of scenes selected according to the ranking.
