摘要： An image of an inspection object is picked up by an image pickup unit, and a characteristics quantity of an image of a defect part extracted by a defect extracting unit is extracted and digitized by a characteristics extracting unit. A database preparing unit regroups defects having similar characteristics by a defect classification unit on the basis of the characteristics information digitized by the characteristics extracting unit with respect to defects belonging to a defect group selected and designated by an operator via a display/input unit, and prepares on a database memory a database in which the defects of the inspection object are hierarchically classified. A classification executing unit hierarchically classifies the defects of the inspection object with reference to the database provided by the database preparing unit on the basis of the digitized characteristics information extracted by the characteristics extracting unit from the image of the defect part of the inspection object extracted by the defect extracting unit. Thus, a defect classification/inspection system having high classification accuracy is provided.

摘要： The present invention provides a position detection apparatus capable of suppressing a crosstalk between a scale signal and an origin signal and detecting a position with a high accuracy. A recording medium 12 of a round bar shape has a magnetic signal alternately reversing the polarity at a predetermined recording wavelength .lambda..sub.1 and recorded as a scale signal in the longitudinal direction of the recording medium 12. This scale signal is recorded over the entire outer circumferential surface of the recording medium 12 and almost over the entire length of the recording medium 12. Moreover, the recording medium 12 has a one-wavelength origin signal of recording wavelength .lambda..sub.2 recorded at least at one position over the scale signal. The recording wavelength .lambda..sub.2 of this origin signal is longer than the recording wavelength .lambda..sub.1 of the scale signal. The origin signal is recorded at a part of the outer circumference. An origin signal detection head is arranged to face the origin signal whereas a scale signal detection head is arranged opposite to the origin signal detection head so as to sandwich the recording medium 12.
