ABSTRACT:
The combination of an X-Y addressed array of charge injection devides (CIDs) and a charge transfer output register system. The array is read out a row at a time by first restoring charge to the columns of the array, then removing the excess charge from the columns to reset them to a reference potential, then causing the photo-induced charge carriers in a row to change the column potentials to extents dependent upon the photo-induced charge levels. This change in potential is employed to supply charge signals in parallel to the charge transfer stages of the output register system.
