ABSTRACT:
The columns in known frame transfer type charge coupled device (CCD) image sensing arrays generally are spaced, center-to-center, a distance equal to the length of a stage in the C register. In the present array the center-to-center spacing of the columns is considerably reduced to obtain improved resolution in the row direction. The spacing is only 1
'th of the length of each such C register stage, where n is the number of phases employed to operate the C register. The array is read out to the C register via a special electrode structure, 1
'th of a row at a time, and the C register is read out in such a way that the row is reconstructed while being read from the C register. The special electrode structure temporarily stores a row of information and permits the 1
'th of the row to be removed at a time. It also provides a potential barrier to isolate the C register during the time the C register is being read out.
