摘要

PPROBLEM TO BE SOLVED: To provide a data processing device which reduces data quantity in case that affiliated data of high-quality image are generated. PSOLUTION: An acute angle point-extracting part 31 extracts acute points, at which angles formed by adjacent line segments are at most a prescribed angle, from a line segment group obtained in a linear approximation part 21. A line segment group between acute angle points is regarded as a line segment group C, and a passing point computation part 32 computes a passing point which a third order Bezier curve, which approximates the line segment group C, is assumed to pass through. A control point computation part 33 solves dual linear simultaneous equations, which are obtained by the assumption that the third order Bezier curve, which approximates the line segment group C, passes through the passing point obtained by the computation by the passing point computation part 32, to compute two control points of the third order Bezier curve. A determination part 34 determines whether an error between the obtained third order Bezier curve and the line segment group C is at least a prescribed value. If the error is at least the prescribed value, a division part 35 divides the line segment group C into line segments to make each line segment group a line segment group C, and again finds a third order Bezier curve.

要解决的问题:提供一种在生成高质量图像的附属数据的情况下减少数据量的数据处理设备。

解决方案:锐角点提取部分31从在线性逼近部分21中获得的线段组中提取由相邻线段形成的角度至多为规定角度的锐点。将锐角点视为线段组C,通过点计算部32计算通过近似于该线段组C的三阶贝塞尔曲线的通过点。控制点计算部分33求解对偶线性联立方程,该对偶线性联立方程是通过假设近似线段组C的三阶贝塞尔曲线通过通过点计算部分32的计算获得的通过点而获得的,计算三阶贝塞尔曲线的两个控制点。判定部34判定所获得的三阶贝塞尔曲线与线段组C之间的误差是否至少为规定值。如果误差至少为规定值,则划分部35将线段组C划分为线段,以使每个线段组成为线段组C,并再次求出三阶贝塞尔曲线。
