An electronic device detects a discontinuous figure in an old-new connection portion between old and new data and performs shape correction so as to restore the continuous figure. In this case, only the old data is corrected. Particular shape correction methods are as follows: (a) only the old-data side shape point P1 in the old-new connection portion is moved to match the new-data side shape point SP1; (b) other shape points P2 to P5 are moved in parallel by the same amount as that of movement of the shape point P1 in the old-new connection portion; and (c) among the old-data side shape points P1 to P5, the farthest shape point P5 from the shape point P1 in the old-new connection portion is not moved as a reference, and the other shape points P1 to P4 are moved in accordance with distance from the farthest shape point P5.
