          Application No. 09/359,523                                                   

          an image sensor may need to be manipulated to adjust a white                 
          color balance in the image or to compensate for other effects                
          introduced by the camera or the data such as stray lighting                  
          effects, lens flare effects and the nonlinearity of the image                
          sensor (specification, page 1).  Appellants use a look-up table              
          for modifying raw pixel data wherein the values of the table may             
          be updated in an iterative calibration process instead of                    
          establishing the values of the table (specification, page 3).  An            
          understanding of the invention can be further derived from a                 
          reading of exemplary independent claim 1, which is reproduced                
          below:                                                                       
                    1.   A method comprising:                                          
               capturing an optical image to form raw data indicative of               
          the optical image;                                                           
               using values in a look-up table to transform the raw data               
          into transformed data indicative of a second image;                          
               computing a white color balance of the second image; and                
               modifying the values in the look-up table based on the                  
          computed white color balance and the values.                                 
               The Examiner relies on the following references in rejecting            
          the claims:
