Patent ID: 7515317

Claim:
A method, comprising: scanning an image with a staggered charge-coupled device (CCD) including a primary scanning line and a secondary scanning line for each color of the CCD, wherein the primary scanning line and the secondary scanning line are separated by a pitch of one or more lines; identifying a leading edge reference line of the image comprised of a number of pixels including a primitive pixel; and determining a compensation value for the image, wherein the compensation value is determined in part according to a mathematical operation comprising a pixel value associated with the primitive pixel and a pixel value associated with one or more pixels located on a scan line of the image, wherein the one or more pixels located on the scan line are separated from the number of pixels of the leading edge reference line by the pitch, and wherein the compensation value compensates for a zipper effect caused by a reflection of light between the primary scanning line and the secondary scanning line of the staggered CCD when the leading edge reference line and the scan line are scanned.
