          Appeal No. 1997-1203                                                        
          Application 08/432,786                                                      





          obtained for the whole frame.  Then, for the sake of                        
          comparison, another difference data is calculated by                        
          subtraction of the DC                                                       
          (low frequency) component in the frame for use as the index                 
          indirectly indicating the quantity of generated data for                    
          intra-frame encoding.  This quantity is then compared with the              
          quantity of data for the inter-frame encoding and if the                    
          quantity of data for the inter-frame encoding is less than                  
          intra-frame encoding, the target frame is inter-frame encoded,              
          otherwise it is intra-frame encoded.  The sole claim 7 is                   
          reproduced as follows:                                                      
               7.   A motion picture encoding system for either intra-                
          frame encoding or inter-frame encoding a motion picture which               
          includes a sequence of frames, comprising:                                  
               a first encoding means for encoding at least a portion of              
          the motion picture by said intra-frame encoding;                            
               a second encoding means for encoding at least a portion                
          of the motion picture by said inter-frame encoding;                         
               means for subtracting a low-frequency component from an                
          intra-frame difference signal for a frame and producing a                   
          first absolute sum signal as a result of the subtracting;                   
               means for producing a second absolute sum signal of                    
                                         -3-
