    摘要： The stereoscopic CG image generating apparatus and a stereoscopic TV apparatus, has a projection transformation section which, based on three-dimensional structural information describing a three-dimensional shape of an object, generates a plurality of two-dimensional projection models as viewed from a plurality of viewpoints, a distance information extraction section which generates a camera-to-object distance information used for calculations in the projection transformation section, and a camera parameter determining section which, based on the output of the distance information extraction section, the screen size of a stereoscopic image display device for displaying finally generated two-dimensional projection models, and a viewer's viewing distance, determines camera parameters so that stereoscopic CG images will be brought within the viewer's binocular fusional range. According to the thus constructed stereoscopic CG image generating apparatus and stereoscopic TV apparatus, proper camera parameters (focal length or field of view, camera spacing, and converging point) are determined based on the camera-to-object distance information, the magnitude of parallax of the generated stereoscopic CG images on the display device (or in a window on the display screen), and the viewing distance, so that easy-to-view stereoscopic CG images are automatically generated regardless of the display size, and by horizontally translating left-eye and right-eye images, binocular parallax of displayed images is automatically brought within the viewer's binocular fusional range regardless of the size of a stereoscopic display used.

    摘要： A camera for taking a state behind a vehicle is installed in a position laterally shifted from the rear center of the vehicle. An image processing unit generates a rear image from a camera image by shifting merely a rectangular area of the camera image so that a vertical center line thereof can substantially accord with the center line along the lengthwise direction of the vehicle. Furthermore, processing for correcting lens distortion may be performed. As a result, when the vehicle is moved straight backward, an object present on the center line of the vehicle moves vertically in substantially the center of the screen, so that a user can be prevented from having an odd feeling to see the image.

    摘要： In the vehicle surroundings display device of the invention, an image processor generates an image showing the situation around a vehicle. When an obstacle is detected by an obstacle detection means, the image processor determines an image missing region using the position of the border of the obstacle on the vehicle side detected by an obstacle position detection means and fills the image missing region with substitute image data. This eliminates unnaturalness of a display image the user may feel and enables the user to accurately recognize the position of a neighboring obstacle that is important in driving operation.

    摘要翻译： 在本发明的车辆周边显示装置中，图像处理器生成表示车辆周围的情况的图像。 当障碍物检测装置检测到障碍物时，图像处理器使用由障碍物位置检测装置检测到的车辆侧的障碍物的边界的位置来确定图像丢失区域，并用替代图像数据填充图像丢失区域。 这消除了用户可能感觉到的显示图像的不自然，并且使用户能够准确地识别在驾驶操作中重要的相邻障碍物的位置。
