Abstract:
1. A recording apparatus comprising: input means for inputting an image signal stream and genre information of the image signal stream; recording means for recording the image signal stream input by said input means on a storage device; storing means for storing a plurality of procedure information, each of the plurality of procedure information including (a) predetermined extraction timings and (b) predetermined extraction periods respectively corresponding to the predetermined extraction timings, to extract parts of image signals, the predetermined extraction timings defining a respective plurality of percentage values, and the plurality of procedure information being preliminarily generated and the plurality of procedure information being respectively associated with a plurality of genre information different from each other; selection means for selecting procedure information from the plurality of procedure information, based on the genre information of the image signal stream, for use when generating a digest image of the image signal stream input by said input means; and extraction means for extracting a part of image signals from the image signal stream to be recorded on the storage device, in accordance with the procedure information selected by said selection means, wherein each of the plurality of predetermined extraction timings is defined by a percentage value, and wherein said extraction means calculates actual extraction timings based on (a) a total time of the image signal stream from which the digest image is generated and (b) the procedure information selected by said selection means, and extracts, at each of the actual extraction timings, a part of image signals from the image signal stream, which part has a predetermined extraction period corresponding to a respective one of the predetermined extraction timings.
