<p><P>PROBLEM TO BE SOLVED: To provide a data converter and a program for the same, for rotating encoded image data by 180 degrees with a light processing load. <P>SOLUTION: The data converter: applies to a first data string which include a plurality of continuous data, differential code string processing in which the first head code in the first data string is used as the head and differential values between the two continuous data in the first data string are used as a plurality of second codes and thereby obtains differential code string; uses the differential code string to calculate a data value at the end of first data string; takes out each of the plurality of second codes included in the differential code string; converts the taken-out plurality of second codes into a plurality of third codes indicating a differential value between the consecutive two data in order of the direction from an end to the head in the first data string; and generates a conversion data string including the calculated data value at the end of the first data string as the head and the plurality of third codes obtained by conversion from the next to the head to the end continuously. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
