  • Patent number: 10635923
    Abstract: An image processing apparatus includes a detector, an estimator and a determiner. The detector detects a candidate region of a captured image captured by a camera, the candidate region serving as a candidate for a water drop region affected by a water drop on the lens of the camera, based on an edge strength of each pixel in the captured image. The estimator estimates, based on the candidate region, a circle that includes the candidate region. The determiner determines whether or not the candidate region is part of the water drop region based on the edge strength of some of the pixels in the circle.

  • Patent number: 10227062
    Abstract: A water-droplet detecting apparatus according to an embodiment includes a setting unit, a first extraction unit, a second extraction unit, and a determination unit. The setting unit sets concentric circles having a center at arbitrary one point of a captured image of an image capturing unit. The first extraction unit extracts candidate pixels based on gradients of pixels on a circumference of each of the concentric circles. The candidate pixels are candidates for pixels that are estimated to indicate a water droplet adhered to the image capturing unit. The second extraction unit extracts one or more candidate circles based on the candidate pixels extracted by the first extraction unit. The one or more candidate circles are candidates for circles that indicate a shape of the water droplet. The determination unit determines whether or not the water droplet is adhered based on an extraction result of the second extraction unit.

  • Patent number: 9965959
    Abstract: A lane departure warning apparatus that issues a warning for a lane departure of a vehicle monitors a change amount of a location of the vehicle relative to a division line that defines a travelling lane, in a case where the lane departure warning apparatus has detected the lane departure of the vehicle from the travelling lane. The lane departure warning apparatus is issues the warning to an output device in at least one of cases in which (i) the change amount monitoring part determines that the change amount of the location of the vehicle is equal to or greater than a first threshold value and (ii) the change amount monitoring part determines that the change amount per a unit of time is equal to or greater than a second threshold value.
