Abstract
A position detection system which performs rough detection processing of detecting a rough position of an approximate position of a check object in a check range based on the comparison result of comparison processing of comparing images provided by compressing the check image and a correct solution image subjected to the detection displacement operation of displacing by rough detection displacement amount at a time in the check image, then performs precise detection processing of detecting a more precise position of the check object in the check range in the proximity of the rough position based on the comparison result of comparison processing of comparing images provided by compressing the check image and the correct solution image subjected to the detection displacement operation of displacing by rough detection displacement amount at a time in the check image at a compression rate more moderate than the previous compression rate, and detects the position of the check object in the check range in multiple steps, wherein the compression processing is average compression processing.
