摘要： A motion-vector-setting section (31) sets a motion vector in units of pixel in a target image. Based on the motion vector, a target-pixel-setting section (35) sets a target pixel for each image in plural images to be processed. A motion-blur-amount-setting section (33) sets a motion blur amount in units of pixel based on the motion vector and the exposure-time ratio set in units of image in the exposure-time-ratio-setting section (32). A processing-region-setting section (36) sets processing regions corresponding to the target pixel for each of the plural images based on the motion blur amount. A processing-coefficient-setting section (37) sets processing coefficients based on the motion blur amount. A pixel-value-generating section (38) generates motion-blur-removed pixel values that correspond to the target pixel by linear combination of pixel values corresponding to pixels in the processing region and the processing coefficients, so that they can be output from an integration section (39) as one pixel value. By utilizing any time-directional information significantly, motion-blur-removing processing can be accurately performed.

摘要翻译： 运动矢量设定部（31）以目标图像中的像素为单位设定运动矢量。 基于运动矢量，目标像素设定部（35）将待处理的多个图像中的各图像的目标像素设定。 运动模糊量设定部（33）基于在曝光时间比设定部（32）中以图像为单位设定的运动矢量和曝光时间比率，以像素为单位设定运动模糊量， 。 处理区域设置部分（36）基于运动模糊量设置与多个图像中的每一个对应的目标像素的处理区域。 处理系数设定部（37）基于运动模糊量来设定处理系数。 像素值生成部（38）通过与处理区域中的像素对应的像素值和处理系数的线性组合，生成与目标像素对应的运动模糊去除像素值，从而可以从 积分部分（39）作为一个像素值。 通过显着地利用任何时间方向信息，可以精确地执行移动模糊消除处理。
