<p>PURPOSE:To prevent the generation of distortion as to a display pattern, etc., by correcting Y coordinates or Y coordinates. CONSTITUTION:Digitalizer unit 1 consists of input board 2, stylus 3, and controller 4 and when a character is written on input board 2 with stylus 3, the character is inputted to Y-axis coordinate position correction processing unit 5 as X-axis and Y- axis coordinate position data under the control of controller 4. Processor 5 corrects the position of the Y-axis coordinate and inputs corrected coordinate position data to computer 6. Computer 6 converts the coordinate position data into data to be displayed on graphic display unit 7 and supplies display control data to unit 7. Furthr, Y-axial correction position y'n is determined by expression I. In expression I, yn-1 is the Y-directional coordinate one read period before and T0 is the measurement time period.</p> |
