Abstract:
A method of resolving photoelectron coupling that results from an operation of a staggered charge-coupled device inside a scanner, wherein the staggered charge-coupled device at least includes an optical sensor group comprising of an optical sensor array and a neighboring optical sensor array for scanning pixels, the method comprising the steps of:recording the quantity of photoelectrons transferred between a first quantity of photoelectrons captured by the optical sensor array and a second quantity of photoelectrons captured by the neighboring optical sensor array during a scanning time interval t; and subtracting the quantity of transferred photoelectrons from the first quantity of photoelectrons captured by the optical sensor array to obtain the correct quantity of photoelectrons captured by the optical sensor array during the scanning time interval t so that correct brightness value for pixels scanned by the optical sensor array is obtained.
