PROBLEM TO BE SOLVED: To provide a filter selection device capable of selecting a filter appropriate for a decoded signal of an encoded signal, which has been coded by an irreversible coding system, with a small amount of calculation.SOLUTION: A filter selection device includes: a determination unit for selecting a candidate filter group from among a plurality of filters with reference to a decoded signal of an irreversibly compressed signal; a filtering unit for applying each filter in the candidate filter group to a decoded signal; a comparison unit for selecting a filter within from candidate filter group by comparing each of decoded signals on which with each filter in the candidate filter group has been applied, and a signal before encoding; and an output unit for outputting information representing a filter selected by the comparison unit. |
