    • There is provided a distance measuring apparatus, which can attain a distance compensation of a high precision and can be stably operated by using a cheap circuit, without any arrival at a supersaturated state for a great reflected light intensity, while a gain of an amplifying circuit is made higher, in order to accurately detect even a weak reflected light. The apparatus comprises: a light source for outputting a pulsed measurement light towards a measurement target object; a light receiver for detecting the reflected light from the measurement target object; and a calculator for calculating the distance from the measurement target object on the basis of the delay time between the output timing of the measurement light and the detected timing of the reflected light by the light receiver, and a light receiver 5 is composed of a photodiode PD for photo-electrically converting the reflected light, a diode D that is connected in series to the photodiode PD and clamps the light current generated in the photodiode PD, and an amplifying circuit 50 for amplifying the output of the photodiode PD, and it contains an integration processor for integrating the output of the amplifying circuit 50 and a distance compensator for compensating the distance in accordance with the output of the integration processor.

    • A navigation apparatus includes a controller, an image data input unit adapted to acquire image data from a camera installed in a vehicle, and an image memory for storing the image data. The navigation apparatus also includes an image processing unit converting data extracted from the acquired image data to data simulating a virtual viewpoint. The image processing unit stores the converted data in the image memory in associated with position data indicating the position at which the image was taken by the camera. Using a plurality of sets of converted data, the image processing unit generates bird's eye view data representing a bird's-eye image of an area nearby the current vehicle position. When the controller determines that parking operation is stopped, the image processing unit displays the bird's eye view image together with a mark indicating the current vehicle position.
    • 导航装置包括控制器,适于从安装在车辆中的相机获取图像数据的图像数据输入单元和用于存储图像数据的图像存储器。 导航装置还包括将从获取的图像数据提取的数据转换成模拟虚拟视点的数据的图像处理单元。 图像处理单元将转换的数据存储在图像存储器中,该位置数据指示照相机拍摄图像的位置。 使用多组转换数据,图像处理单元生成表示当前车辆位置附近区域的鸟瞰图像的鸟瞰图数据。 当控制器确定停车操作停止时,图像处理单元与指示当前车辆位置的标记一起显示鸟瞰图图像。
