<p>PROBLEM TO BE SOLVED: To improve convenience by improving the degree of freedom to tablet parallax correction. SOLUTION: A pen is moved toward a pen display position P at the time of performing table parallax collection. When tablet parallax correction is performed by using voltage values (Vx and Vy) at a point coinciding with the approaching pen display position P and pen display coordinates (Px and Py), the value of a moving coefficient (k) is automatically changed between '-1' and '-0.5' in accordance with the decrease of between '>=50 mm/second' and '<=10 mm/second' of the moving speed of a pen input position. Thus, in a rough adjustment mode in the case deviation quantity is large between the pen input position and the pen display position P, the coefficient (k) is defined as -1 to quickly make the pen input position and the pen display position P close to each other, and meanwhile, in fine adjustment mode when the deviation quantity is small, the coefficient (k) is defined to be smaller than -1 to easily perform fine adjustment. Namely, high operability is obtained in both fine adjustment and rough adjustment in response to operator intention.</p> |
