1. A method of correcting scan-produced artifacts in an interline or full-frame CCD comprising the steps of: scanning the CCD to produce an image having exposed parts comprising rows, such that each row of said exposed part of said image which is read out contains a same readout smear effect; scanning at least one overscan row to produce a readout of said overscan row, which does not contain any part of said exposed part of said image in such a way that said overscan row contains the same readout smear effect as said rows of said exposed portion of said image; subtracting said readout of said overscan row from each row of said readout of said exposed portion of said image to produce a corrected image.
