摘要：A registration adjusting apparatus for a color television camera having aplurality 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 thesegmented image areas, changes the registration control data sequentially at
predetermined intervals and calculates the registration error in every segmented imagearea over the entire image area from the values of the centering control data producedat the time points when the registration errors of the respective segmented image areasare inverted in polarity, thereby to reduce the time necessary for performing registrationadjustment. The registration error data is produced using a test chart of vertical andhorizontal stripes over the segmented image area and by interpolation or extrapolation,the registration error data at the centers of the respective segmented image areas canbe obtained.
