INTERLACED READOUT OF A CHARGE COUPLED ARRAY

摘要

Charges initially are stored in each half Ia and Ib of each stage of a charge coupled device (CCD) array. A first field is obtained from the charges stored during a first time period by combining the charges in the halves Ia and Ib of each stage. A second field which may be interlaced with the first is obtained from the charges stored during a second time period by combining the charge in the Ib half of each stage with the charge in the Ia half of the following stage. The combining of charges may be performed within the photosensing array to obtain vertical interlacing and within the system output register to obtain horizontal interlacing.
