    • 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。

    • Feature points are extracted from an image of a plurality of frames. A blurring direction component of a previous frame image is judged from motion vectors of the next frame image acquired with reference to feature points of the extracted previous frame image. Images of the same blurring direction are selected and grouped from the image of a plurality of frames based on that judgment result. After performing position compensation, an additive composite of a grouped composite image is created for each group so that feature points conform to grouped images. Subsequently, inverse transform filter processing is applied to the grouped composite image data and hand shake compensation by group is accomplished which compensates the blurring direction component matched to a group. Upon position compensation, an additive composite is generated of a hand shake compensated image so that feature points of each grouped composite image conform to hand shake compensation.
    • 从多个帧的图像中提取特征点。 从参考所提取的前一帧图像的特征点获取的下一帧图像的运动矢量来判断先前帧图像的模糊方向分量。 基于该判断结果,从多个帧的图像中选择并分组相同模糊方向的图像。 在执行位置补偿之后,为每个组创建分组合成图像的添加组合,使得特征点符合分组图像。 随后,将逆变换滤波处理应用于分组的合成图像数据,并且通过组完成手抖动补偿,其补偿与组匹配的模糊方向分量。 在位置补偿时,产生手抖补偿图像的添加复合物,使得每个分组合成图像的特征点符合手抖动补偿。
