It can be seen from the Table 2 that the encoding compression rate using the adaptive scanning based on the intra prediction mode according to the present invention is superior to the encoding compression rate using the H.264 zigzag scanning.

Meanwhile, a video compression standard to be developed following the H.264 standard is expected to use only the vertical, horizontal, DC, and diagonal prediction modes, because the existing 9-directional intra prediction mode requires a considerable complexity. Therefore, the encoding method using the adaptive scanning of the present embodiment provides even more improvement in the compression rate to thereby save bits about 3%.

Meanwhile, the moving picture encoding/decoding method described above may be authored in the form of a computer program. The codes and code segments that form the program may be easily inferred by computer programmers of the art to which the present invention pertains. Also, the program is stored in a computer-readable recording medium and it can be read and executed by a computer to realize the moving picture encoding/decoding method. The data storage media include magnetic recording media, optical recording media, and carrier wave media.

While the present invention has been described with respect to certain preferred embodiments, it will be apparent to those skilled in the art that various changes and modifications may be made without departing from the scope of the invention as defined in the following claims.
