Technical Examples
- A digital camera further includes a compression/multiplex section for providing compressed motion picture data by compressing the respective frames constituting a motion picture in a predetermined operation mode, a communication interface for outputting the compressed motion picture data in an appropriate format, and a picture selection unit which permits a user to select a picture. When the user selects a picture, the compression/multiplex section outputs the selected picture instead of compressed motion picture data.
- Method and apparatus for uniquely identifying a copy of a motion picture disposed on a media. The method includes the steps of selecting two or more motion picture scenes. Each of the motion picture scenes is an identifiable portion of the motion picture distinct from every other portion of the motion picture. Once the scenes have been identified, two or more sequences can be defined within each of the motion picture scenes such that each sequence includes two or more frames. For example, the motion picture can have three scenes, each divided into twenty eight sequences, with each of the sequences containing 12 frames. Once the scenes and sequences have been selected, at least one of the sequences from each scene is marked to define a uniquely identifiable marking pattern on the media.
- A moving picture editing method is disclosed, in which if one or two reference frames utilized for motion compensation of P or B frame, constituting a part of moving picture before editing and not deleted in edition so as to constitute moving picture after editing, is subject to error generation in processing although not subject to lack in edition, motion vectors in a range centered on each motion vector V before editing of the P or B frame, are searched for the motion vector V' after editing corresponding to the minimum value of the difference between the motion compensated picture MC (X, V) before edition and motion compensated picture MC (X', V') after editing.
- An apparatus for compressing an uncompressed motion picture to generate compressed motion picture data, and also for generating and including rate correction data to be used by another apparatus to change the bit rate of the compressed motion picture data without decoding all of the encoded packets in the compressed motion picture data.
- A moving picture coding apparatus 1 includes a counter unit 102 which counts the number of pictures following an intra coded picture; and a motion estimation unit 101 which compares respectively only reference pictures which are the intra coded picture or the following pictures, selected from among a reference picture Ref1, a reference picture Ref2 and a reference picture Ref3 stored in memories 408~410, with a picture signal Vin, and determines the reference picture whose inter picture differential value is smallest.
