Title: Method for processing handwritten data with ink data format
Inventor: SAWAMURA MASAYUKI
IPC: G06T3/00
Filed: 1998-12-24
Abstract: PROBLEM TO BE SOLVED: To provide smooth handwritten data without depending upon event intervals generated by a device by automatically compensating a point between points where distance is separated and making the distance between the points equal to or shorter than threshold. SOLUTION: The point sequence data interpolating part of a point sequence data synthesizing part interpolates point sequences, adds fine points 22 between rough points 21a and 21b, 21b and 21c, etc., and preliminarily sets an interval between two respective adjacent points to being equal to or less than threshold. When a handwriting inputting person performs an erasure operation of an range 23 for a line 20 by using an eraser, the erasure range deciding part of the point sequence synthesizing part changes the attributes of point sequences 21c and 22 within the erasure range 23 into non-display and erases the line with the range which is intended by the handwriting inputting person and is almost the same as the range 23. Thus, it is possible to produce smooth handwritten data without depending on an event interval generated by a device.
