Abstract
Methods are disclosed for correcting vertical line streaks in an interline or full-frame CCD. The method includes the step of subtracting an overscan row from each row of a previous image or from each row of a next image, such that each row of the final image contains the same readout smear effect and such that readout overscan rows contain the same smear information as each row of the final image. The method is also described for use with frame transfer CCDs.
