    • A vehicle environment recognition apparatus includes stereo-image taking means for outputting a reference image of the surroundings of a subject vehicle, stereo matching means for correlating a parallax with each pixel block in the reference image by stereo matching, preceding-vehicle detecting means for detecting a preceding vehicle from the reference image on the basis of the parallax or the like, and smear determining means for searching a pixel column vertically extending in the reference image for brightnesses of pixels, the pixel column including a pixel block having a parallax less than or equal to a long-distance parallax threshold value corresponding to the long distance including infinity, and determining that a smear occurs when a ratio of the number of pixels having brightnesses more than or equal to a predetermined brightness to the total number of pixels in the pixel column is more than or equal to a predetermined ratio.
    • 车辆环境识别装置包括立体图像摄取装置,用于输出本车辆的周围环境的参考图像,用于通过立体匹配将视差与参考图像中的每个像素块相关联的立体匹配装置,用于检测的前车检测装置 基于视差等的参考图像的前车,以及用于搜索在参考图像中垂直延伸的像素列用于像素亮度的拖尾确定装置,该像素列包括具有小于或等于视差的视差的像素块, 等于与包括无穷远的长距离相对应的长距离视差阈值,并且当具有大于或等于预定亮度的亮度的像素的数量与像素中的像素总数的比率时,确定拖尾发生 列大于或等于预定比例。

    • A feature video image vdt and a thumbnail picture sdt read from a receiving section C10 are recorded onto a mass storage medium M1, and meta information mdt is recorded into a high-speed storage unit C12. Semantic browser means C1 extracts a partial video image from the feature video image on the basis of the meta information mdt so as to organize a preview video image, and also displays a semantic graph and a current position on the screen on the basis of the meta information and replays the feature video image or the preview video image from that position when there is a position designation input. Furthermore, when there is a browsing instruction input, the semantic browser means C1 carries out browsing between the feature video image and the preview video image, or browsing within the feature video image or within the preview video image. An accounting section C18 carries out accounting processing.
    • 将从接收部分C 10读取的特征视频图像vdt和缩略图像sdt记录在大容量存储介质M 1上,并将元信息mdt记录到高速存储单元C12中。语义浏览器装置C 1提取 基于元信息mdt从特征视频图像的部分视频图像,以便组织预览视频图像,并且还基于元信息在屏幕上显示语义图和当前位置,并且重播特征视频 当有位置指定输入​​时,该图像或来自该位置的预览视频图像。 此外,当存在浏览指示输入时,语义浏览器装置C1执行特征视频图像和预览视频图像之间的浏览,或者在特征视频图像内或在预览视频图像内浏览。 会计科C 18执行会计处理。
