20080231702VEHICLE OUTSIDE DISPLAY SYSTEM AND DISPLAY CONTROL APPARATUS - When any of obstacle sensors detects an obstacle, a distance to the obstacle may be shorter than a reference distance. In such a case a vehicle outside display system clips a detection area corresponding to the obstacle sensor used for the detection from a photographed image supplied from a camera. The system superimposes a detection position of the obstacle on the clipped image and displays the superimposed image without performing viewpoint transformation. When the distance to the obstacle becomes shorter than the reference distance, the system clips a detection area corresponding to the obstacle sensor used for the detection from the photographed image supplied from the camera. The system applies bird's-eye view transformation to the clipped image. The system superimposes a detection position of the obstacle on the clipped image and displays the superimposed image.09-25-2008
20090073263VEHICLE PERIPHERY MONITORING SYSTEM - A vehicle periphery monitoring system takes a view image of a vehicle rear periphery, which is in a predetermined area from the vehicle. This view image is converted into a bird's-eye view image and the bird's-eye view image is displayed in a vehicle compartment to assist rearward movement of a vehicle. As the vehicle approaches an obstacle, the bird's-eye view image is formed by increasing an angle of depression of the bird's-eye view image. A masking section is synthesized with the bird's-eye view image to mask a part of the bird's-eye view image not to be viewed. This masking section is increased as the depression angle increases thereby masking the distorted part of the view image.03-19-2009
