The present invention discloses a method of splicing polarized films. Initially, the area of a N\xd7M pixel CCD sensor array is subdivided into two regions, a large region having pixels in each column for outputting large-amplitude signals with low noise and a smaller region having a pixels in each column for outputting small-amplitude signals with improved dynamic range. Superscript n represents a number between zero and m1, superscript m represents the number of registers, T represents a 01 or 10 pair and G represents a 11 pair.
