Classification: CPC H  G | IPC G  H

Claim 10:
11. The method of claim 8, wherein generating the offset color pixel values includes:
when the target pixel is the blue pixel, generating the offset color pixel values including an offset red pixel value, an offset green pixel value and an offset blue pixel value by following expression

R′=R+OFSbr

G′=G+OFSbg

B′=B 

OFSbr=Bm−Rm 

OFSbg=Bm−Gm 

wherein R, G and B indicate the red pixel value, the green pixel value and the blue pixel value respectively, R′, G′ and B′ indicate the offset red pixel value, the offset green pixel value and the offset blue pixel value respectively, Rm, Gm and Bm indicate the local red average value, the local green average value and the local blue average value respectively, OFSbr and OFSbg indicate a red offset value and a green offset value respectively.
