Filed: 2000-06-15
Abstract: PROBLEM TO BE SOLVED: To allow an operator to perform correction corresponding to the position of each selection point on a display screen by selecting a correction position and to easily perform the continuous correction. SOLUTION: When a touch panel 3 is touched with an input pen 31, a position to be corrected is inputted, and a deviation value at the position is inputted by a cursor key 4.
