Abstract
In an adaptive probability estimation method, an index referring to coding parameters is determined according to occurrence probabilities of symbols from estimated occurrence counts of symbols, thresholds for probability values that determine the probability intervals corresponding to the indexes are set to values that are examined with small operational load, and an index referring to the corresponding occurrence probability is selected without division, using the probability intervals determined by the thresholds for probability values.
