LINE SHAPE PROCESSING DEVICE, LINE SHAPE PROCESSING METHOD, INFORMATION RECORDING MEDIUM, AND PROGRAM

摘要

In order to detect a feature of the end part of a line shape, in a line shape processing device (201), a coordinate storage section (203) associates a first coordinate value of a point on a line inputted by the user with a second coordinate value of the point with respect to the shape of the line and a detecting section (207) determines whether the shape of the end part of the line inputted by the user is (a) a pennant shape in which the vibration width narrows while vibrating, (b) a flag shape vibrating with a substantially constant vibration width, or (c) a normal shape other than (a) and (b) from the stored first and second coordinate values of the point in the shape of the line on the basis of the distribution of the extreme value of the second coordinate value.
