Patent ID: 8532380

Claim:
A processor-implemented method of correcting lateral chromatic aberrations in digital images within a digital image acquisition device, comprising: acquiring a digital image; calculating corrected values for red (R) and blue (B) color channels as follows: R′=R+(G−R)×corR; B′=B+(G−B)×corB; where corR and corB are selected correction ratios for the red and blue color channels, respectively; and outputting, storing, displaying, projecting, or transmitting a corrected digital image which has been corrected for lateral chromatic aberrations, or a further processed version of the digital image, or combinations thereof, and wherein the selected correction ratios corR and corB comprise: CorR={CR= 0.1×clamp([ R ( x,y )− RC ( x,y )],10)}× CRB ; and CorB={CB= 0.1×clamp([ B ( x,y )− BC ( x,y )],10)}× CRB; where clamp (.,.) returns second term when first term exceeds it; and CRB= 1+cos [abs( Rc ( x,y )− Bc ( x,y ))π/200], when abs( Rc ( x,y )− Bc ( x,y ))<200; and CRB= 0 when abs( Rc ( x,y )− Bc ( x,y ))<200.
