Abstract:
1. An image processing device comprising: an obtaining unit for obtaining rough profile vector data composed of a point sequence representing a figure as a sequence of straight lines; a functional approximation interval configuring unit for configuring multiple functional approximation intervals for the obtained rough profile vector data by setting dividing points for dividing the point sequence of the obtained rough profile vector data; a functional approximation unit for functionally approximating each of the configured multiple functional approximation intervals; a calculation unit for calculating an approximation error value for each of the multiple functional approximation intervals; an identification unit for identifying a functional approximation interval having a maximum approximation error value from among the multiple functional approximation intervals based on the calculated approximation error values; an interval dividing unit for setting further multiple functional approximation intervals in the functional approximation interval having the maximum approximation error value identified by said identifying unit; and a determining unit for performing at least one of: wherein the image-processing device repeats the following processes until it is determined by said determining unit that the current amount reaches the pre-defined data amount or the elapsed time exceeds the pre-defined time:
