ABSTRACT:
A solid-state image pickup apparatus of a charge transfer type includes a solid-state imaging device having an array of photosensitive cells with charge divider paths provided for sequentially receiving charges generated in the cells of a horizontal line to divide the charges into two groups for each pixel. For one of the two fields subjected to interlace scanning, charges generated in the cells of odd-numbered lines are transferred to its output port, and one of the two groups of charges for even-numbered horizontal lines adjacent to odd-numbered horizontal lines are discharged. Then, the output port effects addition with weight on the charges from the cells of the odd- and even-numbered lines to produce video signals of the odd-numbered lines. For the other field, on the other hand, charges generated in the cells of even-numbered lines are transferred to the output port, and one of the two groups of charges for odd-numbered horizontal lines are discharged. The output port in turn effects addition with weight on the charges from the cells of the even-numbered lines thus obtained to those of odd-numbered lines previously received to produce video signals of the even-numbered lines. Field flickering is adequately reduced and horizontal resolution of a picture is improved.
