Abstract: An image processing sensor includes an image registering unit configured to register a non-defective product image, a defective product image, and a background image, a differential-image generating unit configured to generate a first differential image from the non-defective product image and the background image and generate a second differential image from the defective product image and the background image; a matching-degree calculating unit configured to calculate a matching degree indicating a degree of feature matching of the second differential image with respect to a model image corresponding to the first differential image, and a threshold calculating unit configured to calculate, on the basis of the matching degree, a threshold used in an operation mode.

Abstract: An image processing sensor includes a threshold calculating unit configured to calculate a threshold with respect to a matching degree indicating a degree of feature matching of a first image including an inspection target object that should be distinguished as a non-defective product and a second image not including the inspection target object that should be distinguished as the non-defective product and a display control unit configured to cause a display unit to display the first image and the second image as images used for the calculation of the threshold by the threshold calculating unit. The display control unit causes the display unit to display, on a first registration screen, as a live image, the one image acquired by the imaging unit, and causes the display unit to display, on a second registration screen, as the live image, the other image acquired by the imaging unit and, as a still image, the already registered one image.

Abstract: Provided is an image processing apparatus which is capable of easily selecting an optimum focus position for an inspection object even when a plurality of candidate focus positions are present. The image processing apparatus according to the invention includes: an imaging unit for imaging a region including an inspection object; a display unit for displaying an image; a focus adjusting unit for adjusting a focus position with respect to the inspection object; and an image processing unit for executing image processing on image data. A plurality of positions where part of the imaged region comes into a focused state are extracted as candidate focus positions, while the focus position with respect to the inspection object is changed, and candidate focus position information is displayed in the display unit. Selection of a focus position is accepted among the plurality of displayed candidate focus positions.
