    • A moving image reproducer includes a generation section, a calculation section, a determination section, a correction section and a control section. The generation section generates an interpolation frame image interpolating between two adjacent frame images among a plurality of frame images. The calculation section sequentially calculates a progress level of a predetermined musical piece between the two adjacent frame images reproduced in synchronization with the predetermined musical piece. The determination section determines whether the progress level has varied along with a change in a tempo of the predetermined musical piece defined in the tempo information. The correction section corrects the progress level so as to reduce the variation in the progress level along with the change in the tempo if the progress level is determined to have varied. The control section controls the generation section to generate an interpolation frame image corresponding to the corrected progress level.
    • 运动图像再现器包括生成部分,计算部分,确定部分,校正部分和控制部分。 生成部生成在多个帧图像之间的两个相邻帧图像之间插值的内插帧图像。 计算部分依次计算与预定乐曲同步地再现的两个相邻帧图像之间的预定乐曲的进行水平。 确定部分确定进度水平是否随着节奏信息中定义的预定乐曲的速度的变化而变化。 校正部分校正进度水平,以便如果进度水平被确定为变化,则减少进度水平的变化以及节奏的变化。 控制部控制生成部,生成与校正后的进度对应的内插帧图像。
