Title:
DATA COMPRESSION METHOD, APPARATUS THEREOF, AND PROGRAM THEREOF
Document Type and Number:
WIPO Patent Application WO/2015/037265
Kind Code:
A1
Abstract:
A computer (1) determines, on the basis of a run length number in a case where image data are to be run-length encoded, a number of bits constituting the notation part in a run length notation variable header. The notation part of the run length number notation variable header has been made variable, so that when the run length number is small, the notation part is shortened and when the run length number is large, the notation part is expanded. The data to be processed are stored on the basis of a storage system using the run length number notation variable header. The length of sequence numbers of the data following the notation part of the run length number can be suppressed, so that a high compression rate can be achieved. Moreover, the run length number that can be described in the notation part can be enlarged and the number of headers can be suppressed, so that a high compression rate can be achieved.
