ABSTRACT:
A solid-state image pickup device includes photoelectric converters in row-column matrix configuration, VCCDs, one for each column, a color filter disposed above each converter to form a color filter array including layouts each including n rows, and a drive circuit for conducting readout treating (m*n) rows as one set, and selecting from the sets a plurality of units symmetrically distributed. Electric charge is read from the plural units. A first readout operation reads electric charge from a first group of rows having asymmetric distribution. A j-row transfer operation transfers the electric charge for j rows. A second readout operation reads electric charge from a second group of rows having asymmetric distribution at positions to which the electric charges are transferred by the j-row transfer operation. The electric charges are added in the VCCDs.
