Abstract: An image processing sensor includes an image-group acquiring unit configured to acquire a plurality of non-defective product candidate images and a plurality of background candidate images, a differential-image generating unit configured to generate a non-defective product-background differential candidate image from a non-defective candidate image and a background candidate image acquired under the same brightness condition candidate among the plurality of brightness condition candidates, a matching-degree calculating unit configured to respectively calculate matching degrees of the background candidate image with respect to pattern models corresponding to non-defective product-background differential candidate images generated for each of the plurality of brightness condition candidates, and a brightness-condition selecting unit configured to select one brightness condition out of the plurality of brightness condition candidates according to a selection condition on the basis of the matching degrees calcula

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.
