    • The present invention relates to a method and an apparatus for driving image pick-up tubes in, particular, a color television camera or the like having more than one image pick-up tube and in particular to a method and an apparatus for driving image pick-up tubes in which the potentials of the cathode electrodes of the respective image pick-up tubes are set to the same common potential, the potential of the target electrode of at least one of the image pick-up tubes is set substantially to earth potential, target drive potentials are individually applied to the target electrodes of the other image pick-up tubes, and the target potential of each image pick-up tube is set to a value near the earth potential, so that a high S/N ratio is obtained. The driving appartatus can be miniaturized and easily driven. According to the invention, a capacitor, such as a chip capcitor or the like, with a low withstanding voltage can be used in a first-stage amplifier to amplify the video signal from the target electrode. This first-stage amplifier can be arranged near a signal output electrode of the target. Thus, the stray capacitance can be reduced.
    • 本发明涉及一种用于驱动图像拾取管的方法和装置,特别是具有多于一个图像拾取管的彩色电视摄像机等,特别涉及一种用于驱动图像拾取的方法和装置 将各个图像拾取管的阴极的电位设定为相同的公共电位的至少一个摄像管的目标电极的电位基本上设定为接地电位的管 将目标驱动电位分别施加到其他摄像管的目标电极,并且将每个摄像管的目标电位设置为接近地电位的值,使得高S / N比为 获得。 驾驶舱可以小型化,易于驾驶。 根据本发明,可以在第一级放大器中使用诸如芯片电容器等具有低耐压的电容器来放大来自目标电极的视频信号。 该第一级放大器可以布置在目标的信号输出电极附近。 因此,可以减小杂散电容。
