Patent number: 7734417Abstract: An image processing device and method for parking support that allows the driver to perceive the state surrounding the vehicle correctly in a simple operation even if plural cameras are carried on the vehicle. Plural images are acquired using plural cameras for image pickup in different directions surrounding the vehicle. These images are used to show the state surrounding the vehicle to the driver, preferably in the form of a bird's-eye view. The view seen by the driver can switch from the bird's-eye view to an image of a desired view. This view can be selected by the driver by, for example, touching the screen upon which the bird's-eye view is displayed.Type: GrantFiled: May 19, 2006Date of Patent: June 8, 2010Assignee: Nissan Motor., Ltd.Inventors: Satoshi Chinomi, Tatsumi Yanai

Patent number: 7046171Abstract: A vehicle surrounding area imaging system is configured to allow a driver to easily view and verify an image surrounding a peripheral side of the vehicle. The vehicle surrounding area imaging system basically has two cameras, a navigation system, a startup imaging determination unit and a monitor. The cameras take images of the areas to the sides of the vehicle to acquire images. The navigation system detects the current position of the vehicle. The startup imaging determination unit detects predetermined road regions that requires an image to be displayed from the periphery around the vehicle based on the current position detected by the navigation system as well as map information. The monitor selectively displays the images acquired by the cameras before the vehicle enters into one of the predetermined road region that requires an image display.Type: GrantFiled: March 25, 2004Date of Patent: May 16, 2006Assignee: Nissan Motor Co., Ltd.Inventor: Tatsumi Yanai
