Zusammenfassung:A camera adapted for taking pictures of a moving scene is disclosed. The camera includes an imaging array, a plurality of charge-coupled device (CCD) shift registers, and a controller. The imaging array includes a plurality of CMOS pixel sensors organized as a plurality of columns and rows. The image moves in the column direction. One CCD shift register corresponds to each of the columns. Each CMOS pixel sensor includes a first transfer gate that transfers charge accumulated in the pixel sensor to a corresponding cell in the CCD shift register. The controller controls the CCD shift registers such that charge stored in a first cell in a CCD shift register is moved to a second cell in the CCD shift register where the charge is combined with charge accumulated by the pixel sensor that is connected to the second cell, the combined charge being generated from the same image pixel.
