    • A registration adjusting apparatus for a color television camera having a plurality of image pick-up tubes in which an effective image area is divided into segmented image areas and the registration adjustment is effected for every one of the segmented image areas, changes the registration control data sequentially at predetermined intervals and calculates the registration error in every segmented image area over the entire image area from the values of the centering control data produced at the time points when the registration errors of the respective segmented image areas are inverted in polarity, thereby to reduce the time necessary for performing registration adjustment. The registration error data is produced using a test chart of vertical and horizontal stripes over the segmented image area and by interpolation or extrapolation, the registration error data at the centers of the respective segmented image areas can be obtained.
    • 一种用于彩色电视摄像机的配准调整装置,其具有多个摄像管,其中有效图像区域被划分成分割图像区域,并且对于每个分割图像区域进行配准调整,改变注册控制数据 按照预定间隔依次按照在分割图像区域的登记误差极性反转的时间点产生的居中控制数据的值,计算整个图像区域中的每个分割图像区域中的登记误差,从而减少 执行注册调整所需的时间。 使用分割图像区域上的垂直和水平条纹的测试图并通过插值或外推来生成登记错误数据,可以获得各分割图像区域的中心处的登记错误数据。
