    • First and second images are separated into luminance and chrominance components to generate a first signal, in which the luminance components of the two images are sequentially located in the 1 H period and a second signal in which the chrominance components of the two images are located in the same. The second signal is delayed by (1/2) H period. The first signal and the delayed second signal are used to generate a third signal in which the luminance and chrominance components of the first image are sequentially located in the 1 H period and a fourth signal in which the luminance and chrominance components of the second image are located in the same. The third and fourth signals are vertically expanded with arbitrary expansion ratios. Then, the expanded signals are synthesized to generate a fifth signal in which the luminance components of the first and second images are sequentially located in the 1 H period and a sixth signal in which the chrominance components of the first and second images are located in the same. The fifth signal is delayed by (1/2) H period. The sixth signal and the delayed fifth signal are interpolated to make uniform the intervals among the scanning lines.
    • 将第一和第二图像分离为亮度和色度分量,以产生第一信号,其中两个图像的亮度分量依次位于1H周期中,而第二信号中两个图像的色度分量位于 一样。 第二个信号延迟(+ E,fra 1/2 + EE)H周期。 第一信号和延迟的第二信号用于产生其中第一图像的亮度和色度分量顺序地位于1HH周期的第三信号和其中第二图像的亮度和色度分量为 位于同一个 第三和第四信号以任意的扩展比垂直展开。 然后,扩展信号被合成以产生其中第一和第二图像的亮度分量依次位于1HH周期中的第五信号和第一和第二图像的色度分量位于第一信号中的第六信号 相同。 第五个信号延迟(+ E,fra 1/2 + EE)H周期。 内插第六信号和延迟的第五信号以使扫描线之间的间隔一致。
