          Application No. 08/192,937                                                  


          overlap pixels when thresholding pixels in a processing                     
          channel near the extremities thereof;                                       
               said method also including the step of:                                
               (c) compressing the thresholded pixels in each of the                  
          processing channels in parallel along a direction which is                  
          perpendicular to said successive non-transposed scan lines of               
          pixels through using reference rows which are parallel to                   
          target rows of thresholded pixels, with each said target row                
          of thresholded pixels having only one pixel from each one of                
          said successive scan lines of pixels, with said splitting and               
          compressing steps, in addition to said thresholding step,                   
          being initiated after said first scan line of pixels is                     
          generated but before said last line of pixels is derived from               
          said scanning                                                               
          said document using the document scanner.
