    Abstract: A decision part decides a representative edge direction using a predetermined angle range as a unit for each pixel area of a plurality of pixel areas of a photographic image photographed by a camera based on an edge angle of each pixel contained in the pixel area. An extractor extracts two of the pixel areas that are adjacent to each other as a pair area among the pixel areas of the photographic image, when the two pixel areas that are adjacent to each other have opposite representative edge directions. A determination part determines whether or not there is an attachable matter on a lens of the camera based on at least one of (1) a number of the pair areas extracted by the extractor and (2) a total sum of edge intensities of the pixel areas contained in the pair areas.

  • Publication number: 20200210740
    Abstract: An attachable matter detection apparatus includes a controller configured to function as an extractor and a detector. The extractor extracts edge information of each pixel contained in a photographic image photographed by an imaging device. The detector detects a candidate area estimated to have a water droplet out of the photographic image based on a matching result between (i) each of the pixels converted into a predetermined data format based on the edge information extracted by the extractor and (ii) a template representing a water droplet and having the data format. The detector calculates a matching frequency with the template for a predetermined area along a contour of the candidate area, and excludes the candidate area when the candidate area satisfies a predetermined exclusion condition based on the matching frequency.
