Abstract:
1. A method of generating inspection logic used in board inspection, the board inspection determining whether a surface-mounted state of a new component is acceptable or defective by checking a color of a focused region in an inspection image of the board surface-mounted new component, the method comprising: storing a reference image of each of a plurality of previously inspected components in a storage device of an information processing apparatus; computing color distribution trend data which indicates a color distribution trend of a focused region in each of the reference images of the previously inspected components; obtaining the image of the new component; computing color distribution trend data which indicates the color distribution trend of the focused region in the inspection image of the new component; selecting the previously inspected component having the color distribution trend similar to that of the new component by comparing the color distribution trend data concerning the new component and the color distribution trend data concerning the previously inspected component; reading the image of the selected previously inspected component from the storage device; and generating the inspection logic of the new component using the inspection image of the new component and the reference image of the read previously inspected component as teaching data; wherein the color distribution trend data is computed based on a distribution on a color space of a color characteristic amount value obtained from a pixel of the focused region, and wherein the method is performed by the information processing apparatus.
