  • Patent number: 11394926
    Abstract: In a periphery monitoring apparatus, a display processing unit displays, in a display apparatus that is provided in a vehicle, a plurality of captured images that are acquired by a plurality of cameras provided in a plurality of differing positions in the vehicle and have overlapping portions in which portions of imaging areas overlap each other, such that the overlapping portions remain. A determining unit determines whether a predetermined target object to be detected is present in each of the plurality of captured images. The display processing unit includes an enlargement processing unit that enlarges at least one captured image in which the target object is determined to be present, among the plurality of captured images, and displays the captured image in the display apparatus when the determining unit determines that the target object is present in at least one of the plurality of captured images.

  • Patent number: 10875452
    Abstract: A driving assistance device converts an image captured by an in-vehicle camera configured to image the periphery of a vehicle into an image viewed from a virtual viewpoint. The driving assistance device combines, as a higher-level layer, a vehicle image indicating the position and shape of the vehicle with a converted target image. The driving assistance device adjusts the opacity of the vehicle image such that the target image as a lower-level layer is visible at a superimposed portion of the vehicle image and the target image. At this point, the opacity of the vehicle image is variably set according to at least one of an own vehicle surrounding condition or a vehicle running condition. The driving assistance device outputs, as a driving assistance image, the target image combined with the adjusted vehicle image.

  • Patent number: 10873725
    Abstract: An image processing unit repeatedly acquires a captured bird's-eye image which is obtained by bird's-eye conversion of a captured image of the surroundings of a vehicle. An image processing unit acquires a history image that is a bird's-eye image corresponding to a predetermined area in front in the traveling direction at each timing determined according to a predetermined condition. The image processing unit acquires a history image at every predetermined first cycle if an unstable condition related to a behavior of the vehicle is not satisfied. If an unstable condition is satisfied, the history image is acquired at a later timing than the first cycle. The image processing unit creates a bird's-eye image for display by extracting an area corresponding to a non-imaging area of the latest captured bird's-eye image from among the accumulated history images, and combining the extracted area with the non-imaging area.
