  • Patent number: 10789502
    Abstract: An extraneous-matter detecting apparatus according to an embodiment includes a first extraction unit, a second extraction unit, and a detection unit. The first extraction extracts a first pixel group of first pixels included in a captured image captured by an image capturing device. Each of the first pixels has a luminance gradient directed outward from a predetermined center region. The second extraction unit extracts a second pixel group of second pixels included in the captured image. Each of the second pixels has a luminance gradient directed inward toward the predetermined center region. The detection unit combines the first pixel group, extracted by the first extraction unit, and the second pixel group, extracted by the second extraction unit, with each other so as to detect an extraneous matter adhered to the image capturing device.

  • Patent number: 10748028
    Abstract: An extraneous-matter detecting apparatus including a dividing unit that divides a captured image into a plurality of regions. The captured image is output from an image capturing device; a computing unit detecting luminance values of pixels included in each of the regions divided by the dividing unit, and computes, for each of target regions, an average value or a standard deviation of luminance values of the detected luminance values. The corresponding target region corresponds to the one or more regions; and a detection unit that extracts the target regions having the average values or the standard deviations of the luminance values computed by the computing unit, which are within a predetermined range, and detects, when the extracted target regions are adjacent to each other, the adjacent target regions as an extraneous-matter region. The extraneous-matter region is a region of the image capturing device to which an extraneous matter is adhered.

  • Publication number: 20200219280
    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.
