<p>PURPOSE:To facilitate the correct input of an aimed graphic by equipping a lattice point setting means to set discrete lattice points designated by coordinates having a prescribed regularity and an input lattice point determining means to obtain the lattice point of the nearest coordinates to the coordinates of the point obtained and indicated with a digitizing means. CONSTITUTION:Lattice points of the coordinates having the regularity expected or required concerning the coordinates of the graphic desired to be input are inputted to a lattice point setting means 2. When an operator indicates the point to be inputted on a picture, a digitizing means 1 reads the coordinates of the indicated point, and makes them into numeric values. An input lattice point setting means 3 obtains the lattice point of the coordinates nearest to the read coordinates. Even if the operator cannot correctly indicate the point having the above-mentioned regularity, when the operator designates the neighboring point to the aimed lattice point on the picture, a graphic recognizing device judges the designated point is the aimed lattice point, and the coordinates of the lattice point are inputted.</p> |
