PROBLEM TO BE SOLVED: To provide a compression encoding method etc. to remedy drawbacks in known data compression techniques.SOLUTION: A compression encoding technique receives a series of data values each represented by a constant number of bits, divides them into groups, and for each group, determines a minimum number of bits that is sufficiently large to encode each of the data values without a loss in data, based on a property of the data values that is common within the group. The technique encodes the data values into encoded data values each represented by the determined minimum number of bits. The technique also appends to each encoded group a data descriptor indicating the determined number of bits used to encode the data values of the group. |
