Abstract
【解決手段】 外観検査装置は、基板等の被検査対象から得られる被検査画像を用いる。外観検査装置は、検査項目毎に、主検査処理部60a〜68aと救済検査処理部60b〜68bを有する。主検査処理部60a〜68aは、被検査対象の良否に応じて異なるロジック検査用パラメータを被検査画像から抽出して、抽出されたロジック検査用パラメータが良品基準を満たすか否かを判定するロジック検査処理を行う。救済査処理部60b〜68bは、主検査処理部60a〜68bで被検査対象が不良であると判定されたとき、被検査画像を予め登録された良品画像と比較するイメージマッチングによって被検査対象が良品として救済可能か否かを判定する。
