Claim One:
1. A method of correcting scan-produced artifacts in an interline CCD having an array of pixel cells arranged into x columns and y rows, each pixel cell comprising a photodiode portion and a charge transfer portion covered by a mask, the method comprising the steps of: exposing the CCD to light to create an image; wherein a portion of the light leaks past the mask into the charge transfer portion of a first pixel cell having a first row and first column position; transferring y rows of x stored charges to an output structure of the CCD to read out said image, wherein during said transferring stored charges in said first column include charge resulting from said leaked light at said first pixel cell; transferring at least one additional row of said stored charges to said output structure; subtracting said additional row from each row of said image to produce a corrected image.
