Abstract
A real picked-up image containing an image of a position detection mark is picked up by an image pickup unit and the real picked-up image is stored in image memory through an interface section . A pseudo image on which change in an image pickup conditions is reflected is generated from the stored real picked-up image by a CPU . When the pseudo image is moved, an image of the object is detected using a predetermined image processing parameter at each move position, and a position detection error of the image of the object relative to the move distance of the pseudo image is calculated.
