Abstract:

An apparatus (10) for correcting for changes in the charge transfer efficiency of a charge coupled device (12) includes a light source (38) for providing synthetic reference images to a preselected portion (26) of the image array (16) of the charge coupled device (12). The initial synthetic reference image is compared with subsequent synthetic references images to determine the changes in the charge transfer efficiency of the charge coupled device (12). The changes are used to correct images form the image array (16).
