PROBLEM TO BE SOLVED: To generate a digest by which a rough content of time series data can be grasped.SOLUTION: From each chapter obtained by segmenting time series data constituted by a plurality of time series data, a chapter segment extraction unit extracts a chapter segment that represents a predetermined chapter portion. Among each chapter obtained by segmenting the time serial data, a feature peak segment extraction unit extracts a feature segment. An effect addition unit combines the chapter segment with the feature segment in the order of time series, to generate a digest that reflects a rough content of the time series data. The present technique is applicable to a recorder for recording contents and the like. |
