Line width measuring device, line width measuring method, image processing apparatus, image processing system, and computer readable medium

摘要

A line width measuring device includes an acquisition unit, an extraction unit, and a generation unit. The acquisition unit that acquires a binary image that is obtained by reading a medium having a line width sample printed thereon with an image reading device, the line width sample representing output characteristics regarding a line width of an image forming device. The extraction unit that extracts a displacement amount of steps that are repeatedly generated in an image corresponding to the line width sample in the binary image by reading the medium with the image reading device in an orientation such that the line width sample has an angle θ (0°θ90°) with respect to a main scanning direction of image reading. The generation unit that generates line width information regarding a width of the line width sample by using the displacement amount extracted by the extraction unit.
