   Summary:筆者らは，記録映像(連続した2次元画像)から無形の伝統芸能(踊り動作)をコンピュータグラフィクスで再現する事を目標としている．本稿では，2次元画像内の対象者の動作を抽出し，この抽出した動作をアニメーションで表現するため，キーフレーム法を用いて踊り動作を補間する手法について検討をおこなった．本手法により，記録映像内の動作を表現することができ，アニメーションで表現する可能性を示した． Recently, the researches of digital archive that preserves and reproduces the traditional performing arts by the dance researcher of the humanities and the researcher of the informatics have been widely carried out. Most intangible traditional performing arts were preserved as recorded images. It is important to preserve the recorded images as a digital archives. There has been no study that tried to preserve intangible traditional performing arts in digital information. It is difficult to reproduce the dance of object person from recorded image. On our studies, we have focused on traditional performing arts recorded in images. In this study, we aim to reproduce dance motion of recorded images. Then, this paper was examined about an interpolation method in the reproduction of the dance motion. To reproduce the dance motion, we define the word of "Rhythm Points" or the time of the start and the end of the motion. We introduced new terms for these variables in the formula of the splines and we designed our spline curve for the change of the angle of the knee to interpolate frames. As a result, we got good result compared to spline before. However, we have carried out the examination for the control point. Our studies need to examine the interpolation method in the continued motion. Then, we added the condition of the period spline, and it was examined again. We also got a good result on this technique. Our studies found the possibility of digital saving of the traditional performing arts preserved as recorded image.
