Claim 13:
14. The data compression device according to claim 13, wherein the processing unit comprises a comparing unit, a preprocessing unit and an encoding unit, wherein
the comparing unit is configured to compare the respective occurrence probabilities obtained by the obtaining unit with a predetermined threshold, to determine, from the plurality of values obtained from the obtaining unit, a first set of values with the respective occurrence probabilities less than the predetermined threshold and a second set of values with the respective occurrence probabilities greater than or equal to the predetermined threshold;
the preprocessing unit is configured to obtain respective original encoded codewords of the first set of values by performing quantized encoding on the plurality of values; and
the encoding unit is configured to encode the second set of values obtained from the comparing unit and the first set of values preprocessed by the preprocessing unit.
