          Appeal No. 95-2827                                                          
          Application 07/983,211                                                      

          nearest previously generated output pixel in the manner                     
          generally referred to in each independent claim on appeal.                  
               After due consideration of the issues as developed by the              
          examiner and appellant, and the disclosed invention as well as              
          the teachings and suggestions of the prior art relied on, it                
          is clear to us that the examiner has misapplied the meaning                 
          of the word “density” as taught by Itoh.  We begin with the                 
          consideration of some basic teachings in Eschbach.                          
               At column 1, lines 10 to 18, it is indicated in the                    
          background portion of this reference that image information                 
          commonly generated in a bitmap format comprises “a plurality                
          of gray level pixels, i.e. pixels that are defined by digital               
          values, each value representing a gray level among a number of              
          gray levels.  Thus, in an 8 bit system, 256 levels of gray are              
          present, where each level represents an increment of gray                   
          between black and white.”  Eschbach goes on to discuss gray                 
          level pixel                                                                 
          values being converted to binary level pixel values,                        
          indicating at column 3, lines 39 to 42 “each pixel                          
          representing an optical density of the image at a location
