ABSTRACT:
A controlling method for a charge-coupled device according to the present invention decreases the amount of ineffectual electric charges by applying a photo shield film over photo sensing elements or a semiconductor substrate with a certain voltage level, then accumulating effectual electric charges in the presence of an optical radiation into the photo sensing elements in applying a different voltage level to the photo shield film for promoting the production of the effectual electric charges while the reduced ineffectual electric charges are swept into the overflow drain, then transferring the effectual electric charges to the multiple-stage horizontal shift register.
