    • A video signal recording/reproducing apparatus in which video tracks continuously arranged on a magnetic tape are sequentially and periodically classified into first to fourth tracks. A video signal is recorded on the first track such that its phase is alternately inverted for every other horizontal scanning period. A video signal is recorded on the second track such that its phase is kept noninverted. A video signal is recorded on the third track such that its phase is alternately inverted for every other horizontal scanning period in the order opposite to that in the first track. A video signal is recorded on the fourth track such that its phase is inverted. In the reproduction mode, the phases of the reproduction signals are aligned. The reproduction signal is processed together with a corresponding 1H delay signal.
    • 其中连续布置在磁带上的视频轨迹的视频信号记录/再现装置被顺序地和周期地分类为第一至第四磁道。 视频信号被记录在第一轨道上,使得其相位在每隔一个水平扫描周期中交替反转。 视频信号被记录在第二磁道上,使得其相位保持不变。 视频信号被记录在第三磁道上,使得其相位以与第一磁道相反的顺序的每隔一个水平扫描周期交替地反相。 视频信号被记录在第四磁道上,使得其相位被反转。 在再现模式中,再现信号的相位被对准。 再生信号与相应的1H延迟信号一起处理。

    • A picking-up apparatus such as a color television camera for converting an image of an object to be picked-up into an electrical picture signal comprises a lens system such as an objective lens system for forming the image of the object on an image plane, a scanner comprising a swingable plane mirror for optically scanning the image of the object in a first direction, i.e. a vertical direction of a television raster scan, at least one linear image sensor array of self-scanning type arranged in said image plane in a second direction which is perpendicular to the first direction; i.e. a horizontal direction of the television raster scan, and a control and process circuit for driving the scanner and linear image sensor array in synchronism with each other.
