Solid state image sensing device providing sub-sampling mode improving dynamic range and driving method thereof

The solid-state image sensor and its drive method for providing a sub-sampling mode, which improves the dynamic range is disclosed. The solid-state image pickup device using the vertical drive electrode receiving the vertical drive signal from the vertical CCD, and the image signal separated by a number proportional to the number of the row receiving each of the image signals of a plurality of rows that with the first row spacing The combined and vertical transfer. In the horizontal CCD using the horizontal drive electrode receiving a horizontal drive signal to the receiving and the combined image signal are combined in turn by the number of the multiple line again, and outputs the horizontal transfer of the combined line-by-line image signal.
