Abstract
An object extracting method of extracting a position of an object in a to-be-inspected region through an image processing, includes the steps of obtaining a plurality of density values of brightness from the to-be-inspected region, converting the density value which is larger or smaller than a preset threshold value into a specified value, integrating the density values at an X or Y coordinate on a Y or X axis, projecting the integrated density values at the X or Y axis, and extracting the position of the object present in the to-be-inspected region based on change of the integrated density values.
