Method for determining restored scanning position

Abstract

A method for position restoration. By comparing the graphic data and the restored graphic data, the graphic data closest to the restored graphic data is selected. Therefore, the graphic data scanned subsequently is correctly connected to the restored graphic data to avoid the missing line or repetition of graphic data.

         7 . A method, comprising: 
 moving a scanning head in a first direction to obtain first image data;    designating a portion of the first image data as connecting image data;    moving the scanning head in the first direction to obtain second image data, the second image data including at least a portion of said connecting image data; and    combining at least a portion of the first and second image data based, at least in part, on a comparison of the connecting image data included in said first image data with the connecting image data included in said second image data.    
     
     
         8 . The method of  claim 7 , further comprising moving the scanning head in a second direction opposite said first direction prior to obtaining said second image data.  
     
     
         9 . The method of  claim 8 , wherein at least a portion of the second image data includes image data that is also included in said first image data.  
     
     
         10 . The method of  claim 7 , and further comprising determining said comparison by combining the connecting data of said first image data with the connecting data of said second image data.  
     
     
         11 . The method of  claim 10 , wherein the combined first and second image data comprises third image data.  
     
     
         12 . The method of  claim 11 , wherein the third image data comprises a complete image of the document.  
     
     
         13 . The method of  claim 7 , wherein the first image data comprises a first plurality of pixel values, and the second image data comprises a second plurality of pixel values, and wherein comparing comprises comparing a portion of the second plurality of pixel values to a portion of the first plurality of pixel values.  
     
     
         14 . The method of  claim 7 , wherein the connecting data comprises image data obtained near a stopping point of the scanning head.  
     
     
         15 . A method, comprising: 
 performing a first scan of a document to obtain first image data for a portion of the document;    designating a portion of the first image data as connecting data;    performing a second scan of the document to obtain second image data for a portion of the document, at least a portion of the second image data including the same image data as obtained from said first scan; and    combining the first and second image data by use of the connecting data to form a third image.    
     
     
         16 . The method of  claim 15 , wherein said combining comprises combining the first image data with the portion of the second image data not including the same image data as obtained from said first scan.  
     
     
         17 . The method of  claim 15 , wherein the third image comprises a complete image of the document.  
     
     
         18 . The method of  claim 15 , wherein the connecting data comprises image data obtained near a stopping point of a scanning head after the first scan.  
     
     
         19 . An article comprising: a storage medium having stored thereon instructions that, when executed, result in: 
 moving a scanning head along a first direction to obtain first image data;    stopping the scanning head at a stopping point, and designating a portion of the obtained image data as connecting image data;    moving the scanning head along the first direction to obtain second image data, the second image data including at least a portion of said connecting image data;    comparing the connecting image data included in said first image data with the connecting image data included in said second image data; and    combining at least a portion of the first and second image data based on the comparing.    
     
     
         20 . The article of  claim 19 , wherein the instructions, when executed, further result in: moving the scanning head a second direction opposite said first direction prior to obtaining said second image data.  
     
     
         21 . The article of  claim 19 , wherein the instructions, when executed, further result in: 
 combining the connecting data of said first image data with the connecting data of said second image data.    
     
     
         22 . The article of  claim 19 , wherein the combined first and second image data comprises third image data.  
     
     
         23 . The article of  claim 22 , wherein the third image data comprises a complete image of the document.  
     
     
         24 . The article of  claim 19 , wherein the first image data comprises a first plurality of pixel values, and the second image data comprises a second plurality of pixel values, and wherein the instructions, when further executed, further result in: 
 comparing a portion of the second plurality of pixel values to a portion of the first plurality of pixel values.    
     
     
         25 . The article of  claim 19 , wherein the connecting data comprises image data obtained near the stopping point.  
     
     
         26 . An article comprising: a storage medium, having stored thereon instructions, that, when executed, result in: 
 performing a first scan of a document to obtain first image data for a portion of the document;    designating a portion of the first image data as connecting data;    performing a second scan of the document to obtain second image data for a portion of the document, at least a portion of the second image data including the same image data as obtained from said first scan; and    combining the first and second image data by use of the connecting data to form a third image.    
     
     
         27 . The article of  claim 26 , wherein the instructions, when further executed, further results in: 
 combining the first image data with the portion of the second image data not including the same image data as obtained from said first scan.    
     
     
         28 . The article of  claim 26 , wherein the third image comprises a complete image of the document.  
     
     
         29 . The article of  claim 26 , wherein the connecting data comprises image data obtained near the stopping point.
