Abstract
A figure digitizing system is described which reduces the operator's labor and enables even unskilled operators to digitize figures easily and accurately. The operator places a drawing to be read on an image information reader and points to characteristic points of the drawing by means of a cursor equipped with an image reader. A CPU operates in accordance with a program loaded from an external memory unit to determine the coordinates of the characteristic points and to display marks of the characteristic points on a display unit. The operator enters the drawing into the system while viewing the marks of characteristic points displayed on the display unit.

A figure digitizing system, comprising:
- pointing means for specifying an intended characteristic point of a figure, wherein the intended characteristic point is one of at least a corner point, a curve point and an end point;
- pointing means position determining means for determining nominal position coordinates of the intended characteristic point;
- reading means for reading image information from the figure at a plurality of positions near the intended characteristic point specified by the pointing means;
- reading means position determining means for determining relative position coordinates of the plurality of positions of the image information read by the reading means, relative position coordinates being relative to the nominal position coordinates of the intended characteristic point;
- characteristic point coordinate determining means for determining actual position coordinates of the intended characteristic point specified by the pointing means based on the relative position coordinates of the plurality of positions of the image information determined by the reading means position determining means and the nominal position coordinates of the intended characteristic point determined by the pointing means position determining means.
A figure digitizing method, comprising:
- specifying an intended characteristic point of a figure, wherein the intended characteristic point is one of at least a corner point, a curve point and an end point;
- reading image information at a plurality of positions near the intended characteristic point;
- determining coordinates of at least one of the plurality of positions of the read image information;
- and
- determining coordinates of the intended characteristic point based on the determined coordinates of the image information.
