Abstract
An image processing apparatus which uses morphology is provided. A masked image is provided to a morphological processing section of the image processing apparatus. The morphological processing section calculates the opening gap of the masked image, calculates the minimum number N of iterations of dilations required for filling the opening gap and, after performing N dilations, executes N erosions to remove a mesh pattern. Then, an edge detecting section detects the edges of a wiring pattern in the image and a measuring section calculates the distance between the edges, which is the width of the wiring.
