<p>PURPOSE:To input many distributed coordinate points with one operation of a pen or the like to prevent the lowering of the quality of an input pattern, by reading out contents of a deviation memory successively when a coordinate value is inputted from the pen or the like and calculating a coordinate value of the sum or the difference between the coordinate value and the deviation value. CONSTITUTION:A position on a tablet 105 is indicated by a pen 107 or the like, and a coordinate value corresponding to a deviation value for the coordinate value corresponding to the position of the pen 107 or the like is stored in a deviation value memory 116 by opening a memory gate 117. When the coordinate value is inputted from the pen 107 or the like, contents of the memory 116 are read out successively to X and Y adders 124 and 125 and a discriminating circuit 133. A coordinate value of the sum or the difference between coordinate values from X and Y registers 114 and 115 and the deviation value from the memory 116 is calculated in adders 124 and 125, and the calculated coordinate value is applied to a picture memory 130 together with the discrimination result of the circuit 133, and they are stored while preventing the lowering of the quality of the input pattern.</p> |
