    Abstract: A camera device includes image capturing device, a lens cleaning device, an adhesion state assessment unit and a controller. The image capturing device is installed on a vehicle and has a lens for forming an image of the vehicle surroundings. The lens cleaning device cleans the lens by spraying a cleaning fluid on the lens in accordance with a predetermined lens cleaning step, in which at least a supply time for supplying cleaning fluid to the lens surface is predetermined. The adhesion state assessment unit is programmed to assess an adhesion state of contamination from a distribution of pixels corresponding to foreign matter adhered to the lens based on a captured image. The controller is programmed to extend the time until a time to start supplying the cleaning fluid in the lens cleaning step as the number of pixels corresponding to foreign matter adhered to the lens increases.

  • Patent number: 8421863
    Abstract: Provided is an in-vehicle image display device capable of providing, from among images of the peripheral area of a vehicle that can change in accordance with the driving state, an image of a part needed by the driver at an appropriate timing so that the driver can recognize the positional relationship between the vehicle and the peripheral area of the vehicle. Images captured with in-vehicle cameras are acquired, and a vehicle periphery image is generated from such images. Then, a collision-warned part of the vehicle that has a possibility of hitting a nearby object is selected based on the vehicle driving state, and the acquired image is processed to generate an enlarged image of the peripheral area of the collision-warned part of the vehicle selected by the collision-warned part selection part. Then, a composite display image, in which the positions of the enlarged image and the vehicle periphery image are displayed in a correlated manner, is generated and displayed.

  • Patent number: 8289391
    Abstract: There is provided apparatus for vehicle surroundings monitorings that assists so as to make it possible for a driver to check the periphery of the vehicle with ease. Plural images are obtained by capturing the periphery of the vehicle with mutually differing exposure. A process of image recognition is then performed for a target within the thus obtained images. The images are then compared, and images for which the accuracy of image recognition of the target is favorable are selected from among the images. The selected images are joined and composited to generate a host vehicle periphery composite image. Thus, an image with a wide dynamic range and high visibility is generated, thereby making it easier for the driver to check the periphery of the vehicle.
