    • An apparatus for photographing a moving body. A video memory including a plurality of frame memories is used in order to store frame images obtained by a plurality of photographing operations. The frame images obtained by photographing are sequentially stored in any of frame memories. Any of a plurality of frame memories is selected in accordance with a detection of a front edge or a rear edge of a vehicle, and a frame image in a selected frame memory is used. A speed of a vehicle is used for this selection. In another case, apparatuses for photographing, such as TV cameras or storage devices such as video memories are provided in a plurality of systems, and a frame relating to either of the systems is selected in accordance with the speed. The high speed processing is enabled without image processings such as clipping of characters on a license plate.
    • 一种拍摄移动体的装置。 使用包括多个帧存储器的视频存储器来存储通过多次拍摄操作获得的帧图像。 通过拍摄获得的帧图像被顺序地存储在任何帧存储器中。 根据车辆的前边缘或后边缘的检测来选择多个帧存储器中的任何一个,并且使用所选择的帧存储器中的帧图像。 车辆的速度用于此选择。 在另一种情况下,在多个系统中提供诸如TV摄像机或诸如视频存储器的存储设备的拍摄设备,并且根据速度选择与任一系统有关的帧。 无需进行图像处理,如削减车牌上的字符,就可以进行高速处理。
