To adjust cycles of respective changes in a plurality of moving images obtained by photographing periodic movements of a subject by a constitution which is more simple than before.SOLUTION: A medical image management device includes: first moving image acquisition means for acquiring a first moving image； second image acquisition means for acquiring a second moving image obtained by photographing separately from the first moving image； first characteristic extraction means for extracting a first characteristic which is a characteristic of a periodic change in the acquired first moving image； second characteristic extraction means for extracting a second characteristic which is a characteristic of a periodic change in the acquired second moving image； image adjusting means for adjusting at least one of the first moving image and the second moving image in a manner that the cycle of the change approximates the cycle of the change in the other moving image based on the extracted first characteristic and second characteristic； and output means for outputting the acquired first moving image or the adjusted first moving image and the acquired second moving image or the adjusted second moving image.SELECTED DRAWING: Figure 3【課題】被検者の周期的な動作を撮影して得られる複数の動画におけるそれぞれの変化の周期を、従来よりも簡素な構成で調整できるようにする。【解決手段】第一動画を取得する第一動画取得手段と、第一動画の撮影とは別に撮影して得られた第二動画を取得する第二画像取得手段と、取得した第一動画における周期的な変化の特徴である第一特徴を抽出する第一特徴抽出手段と、取得した第二動画における周期的な変化の特徴である第二特徴を抽出する第二特徴抽出手段と、抽出した第一特徴及び第二特徴に基づいて、第一動画と第二動画のうちの少なくとも一方の動画を、その変化の周期が他方の動画における変化の周期に近づくように調整する画像調整手段と、取得した第一動画又は調整した第一動画と、取得した第二動画又は調整した第二動画と、を出力する出力手段と、を備える。【選択図】図３
