    • Embodiments of the present invention include a camera having two modes: a visible light imaging mode (day-mode) and an IR imaging mode (night-mode). In the visible light imaging mode, an IR filter is in line with the lens assembly. In the IR imaging mode, the IR filter is mechanically removed, and IR light is allowed to pass to the sensor. In one embodiment, in the IR imaging mode, IR lighting is provided by an IR LEDs on the camera to illuminate the scene. In one embodiment, the various components are chosen, balanced and optimized so that images captured using visible light and images captured using non-visible light are both in focus. In one embodiment, an algorithm determines when there sufficient visible light is present and when it is not, and thus determines when to switch the camera from one mode to another.
    • 本发明的实施例包括具有两种模式的相机:可见光成像模式(日模式)和IR成像模式(夜模式)。 在可见光成像模式下,IR滤光片与透镜组件一致。 在红外成像模式下,IR滤光片被机械去除,并允许红外光通过传感器。 在一个实施例中,在IR成像模式中,IR照明由相机上的IR LED提供以照亮场景。 在一个实施例中,选择,平衡和优化各种组件,使得使用可见光捕获的图像和使用不可见光捕获的图像都是焦点。 在一个实施例中,一种算法确定何时存在足够的可见光,何时不存在,并且因此确定何时将相机从一种模式切换到另一种模式。

    • A motion detection method of a video camera includes calculating differences for a sum of accumulated differences (ΔSAD) for corresponding macro blocks in successive frames of video. The method may include identifying motion-generative macroblocks and regions of connected macroblocks. Candidate-motion regions may be defined in a frame and a bounding box may be formed around each of the candidate-motion regions. If corresponding bounding boxes in a plurality of successive frames have substantially the same location, size, and shape in the plurality of successive frames, and if the plurality of successive frames are in a temporal window of successive frames, then the corresponding bounding boxes may indicate motion.
    • 视频摄像机的运动检测方法包括对连续的视频帧中的相应宏块计算累加差值(&Dgr; SAD)之和的差异。 该方法可以包括识别运动生成宏块和连接的宏块的区域。 可以在帧中定义候选运动区域,并且围绕每个候选运动区域形成边界框。 如果多个连续帧中的对应边界框具有在多个连续帧中具有基本相同的位置,大小和形状,并且如果多个连续帧处于连续帧的时间窗口中,则对应的边界框可以指示 运动。

    • A document management system enables multiple users to collaboratively contribute to the contents of a document via any suitable medium for transporting and storing documents, including email, shared drives, replicated work spaces and centralized storage systems. A tracking strategy is employed, in lieu of a central repository, that is based upon medium-independent versioning. Each version of a document that is created and saved by a user is given a unique identifier. The versions are submitted to a global service for ratification as the next authoritative version of a document. A submitted version that forms the next step in a linear sequence is ratified as the authoritative version of the document, whereas the version which does not meet this criterion becomes identified as a new document. Support is provided for users who create versions off-line, as well as users who are not subscribers to the system.
    • 文档管理系统使得多个用户可以通过任何适合的介质来协作地贡献文档的内容,用于传输和存储文档,包括电子邮件,共享驱动器,复制的工作空间和集中的存储系统。 采用跟踪策略,代替中央存储库,其基于中等独立的版本控制。 用户创建和保存的每个版本的文档都被赋予一个唯一的标识符。 这些版本被提交给全球服务部门批准,作为文件的下一个权威版本。 以线性顺序形成下一步的提交版本被批准为文档的权威版本,而不符合该标准的版本被识别为新文档。 为离线创建版本的用户以及不是系统订阅者的用户提供支持。
