Abstract
An electronic imaging system is provided that records both motion and still video images. In a motion mode of operation, the electronic imaging system records NTSC resolution images at a standard thirty frame per second rate. In a still mode of operation, the electronic imaging system records megapixel resolution still images at a much lower frame rate. The electronic imaging system utilizes an electronic image sensor that incorporates column selective "charge clearing" structures and column selective "charge parking" structures. The charge clearing structures are used to selectively discard the signal charge from certain color pixels. The charge parking structures are used to sum the charge from multiple vertical pixels. The architecture of the electronic image sensor also allows different image aspect ratios to be provided for the motion and still modes described above.
