Abstract

In order to provide a high-speed, inexpensive inspection system that has a short development period, that is flexible, and that allow algorithms to be easily changed, a PC equipped with an image input feature is used to capture an image detected by a line image sensor, this detected image is transferred to a plurality of PCs connected by a LAN, and defects are detected using software processing on the plurality of PCs.
