    • According to one embodiment, an interpolation frame generation apparatus generates an interpolation frame image to be inserted between continuous frame images. The interpolation frame generation apparatus includes a motion vector detection module and a generation module. The motion vector detection module is configured to execute block matching processing in each of a plurality of blocks included in the continuous frame images and specify one motion vector on an interpolation frame. The generation module is configured to, for an interpolation block in which the motion vector detection module specifies one motion vector, generate an interpolation frame image based on the motion vector, and for an interpolation block in which the motion vector detection module does not specify one motion vector, generate an interpolation frame image based on the frame image containing no motion vector component.
    • 根据一个实施例,插值帧生成装置生成要插入连续帧图像之间的插值帧图像。 内插帧生成装置包括运动矢量检测模块和生成模块。 运动矢量检测模块被配置为在连续帧图像中包括的多个块中的每一个块中执行块匹配处理,并且在内插帧上指定一个运动矢量。 生成模块被配置为对于其中运动矢量检测模块指定一个运动矢量的内插块,基于运动矢量生成内插帧图像,并且对于其中运动矢量检测模块未指定一个的内插块 运动矢量,基于不包含运动矢量分量的帧图像生成插值帧图像。
