PROBLEM TO BE SOLVED: To reduce degradation of a parallel processing capability.SOLUTION: In an animation decoding process device, the information of a plurality of first and second frames are supplied to first and second decoding process parts 20, 21 respectively from a decoding control part 10. For the purpose of decoding as far as an end point from a halfway point of a second preceding frame P1 of the second decoding part 21 in a third period T2, an end signal PEN0 prohibits use of a process result of the first decoding part 20 in the third period T2, and permits use of the process result of a first preceding frame I0 of the first decoding part 20 in a second period T1. By reaching to a halfway point of decoding of the second preceding frame P1 of the second decoding part 21 in the second period T1, the information to a halfway point from a start point of a first following frame P2 that is contained in the plurality of first frames in the third period T2 is decoded by the first decoding part 20. 【課題】並列処理能力の低下を軽減すること。【解決手段】動画像復号処理装置で、復号制御部１０から第１と第２の複数のフレームの情報が第１と第２の復号処理部２０、２１にそれぞれ供給される。第３期間Ｔ２の第２復号部２１の第２の先行フレームＰ１の途中点から終了点の復号のために、終了信号ＰＥＮ０により第３期間Ｔ２の第１復号部２０の処理結果の使用が禁止され、第２期間Ｔ１の第１復号部２０の第１の先行フレームＩ０の処理結果の使用が許可される。第２期間Ｔ１の第２復号部２１の第２の先行フレームＰ１の復号の途中点の到達により、第３期間Ｔ２で第１の複数のフレームに含まれた第１の後続フレームＰ２の開始点から途中点の情報が第１復号部２０によって復号される。【選択図】図１
