摘要： An HDTV signal (dot density: 2N dots/line) is converted into a luminance signal and a line sequential color signal, and the resulting signals are both subjected to vertical interpolation and vertical filtering to derive a sequential scanning luminance signal and a sequential scanning color signal. The resulting sequential scanning luminance signal and sequential scanning color signal are subjected to frame thinning to reduce the frequency thereof to a half. Then, subsampling is performed to reduce the dot density to N dots/line. Next, dot rearranging for distributing adjacent dots to adjacent lines is performed to double the number of frames, whereby the dot density of each frame is reduced to N/2 dots/line. These consequently derived frames are encoded for recording. In this manner, the frequency bandwidth required to a recording medium for recording HDTV signals can be reduced.
摘要翻译：将HDTV信号（点密度：2N点/线）转换为亮度信号和行顺序彩色信号，并且对所得到的信号进行垂直内插和垂直滤波以得到顺序扫描亮度信号和顺序扫描颜色信号。所得到的顺序扫描亮度信号和顺序扫描彩色信号经历帧间间隔以将其频率降低到一半。然后，进行子采样以将点密度降低到N点/线。接下来，执行用于将相邻点分布到相邻行的点重新排列以使帧的数量加倍，由此将每帧的点密度减小到N / 2个点/行。这些因此导出的帧被编码用于记录。以这种方式，可以减少用于记录HDTV信号的记录介质所需的频率带宽。

摘要： Frequency analysis is performed on an image signal on a pixel by pixel basis or on a block by block basis, each block including a plurality of pixels, for each frame of the image signal. Then, a motion level or blur level is calculated on a pixel by pixel basis or on a block by block basis in accordance with a result of the frequency analysis. After the calculated motion level or blur level is converted into a binary value, 2-dimensional continuous regions are detected and a large region is extracted from the detected regions. It is then determined whether the large region is a blocker part based on at least one of an area ratio, a shape, and a position of the large region.

摘要： In a recording apparatus, a high-speed camera continuously shoots a series of images at a high shutter speed. Next, an MV calculating unit calculates motion vectors, based on a sequential relationship of the series of images shot by the high-speed camera. Then, a recorder records the images shot by the high-speed camera, together with the motion vectors corresponding to the images. On the other hand, in a reproducing apparatus, the series of images recorded by the recorder are reproduced, with the motion vectors recorded by the recording apparatus added thereto.
