    • The digital image recording system of the present invention comprises event storage unit for storing, on occurrence of an event, the order of such occurrence, importance level storage unit for storing the importance level of the event, and image acquisition unit for sequentially importing the image information from a plurality of image taking unit connection with each event and recording it in accordance with the information stored in these storage unit. On generation of an alarm, the image acquisition unit also stores, by multiprocessing, alarm image information provided from corresponding image taking unit. On occurrence of an event, the event storage unit stores the channel number for the corresponding image taking unit in the order of event occurrence, but does not additionally store such channel if the event storage unit already contains the same channel number as the one for the image taking unit in connection with the event occurrence.
    • 本发明的数字图像记录系统包括:事件存储单元,用于在发生事件时存储该事件的顺序,用于存储事件的重要性级别的重要度级别存储单元,以及用于顺序导入图像的图像获取单元 来自与每个事件的多个摄像单元连接的信息,并根据存储在这些存储单元中的信息进行记录。 在产生警报时,图像获取单元还通过多处理存储从相应的摄像单元提供的警报图像信息。 在事件发生时,事件存储单元以事件发生的顺序存储对应的摄像单元的频道号,但是如果事件存储单元已经包含与用于 图像拍摄单元与事件发生有关。

    • System, method and computer program product for searching through multiple databases based on a search expression. Distribution of records corresponding to search keys in the database is defined. The search expression is divided into multiple search expressions based in part on the defined distribution of records. Respective, target search ranges are determined for the multiple search expressions such that a number of records to be searched with each of the multiple search expressions is approximately constant. The multiple search expressions are executed in their respective, target search ranges. The search ranges can also be determined for the multiple search expressions based in part on search rates through respective search ranges.
    • 基于搜索表达式搜索多个数据库的系统,方法和计算机程序产品。 定义与数据库中的搜索键相对应的记录的分发。 搜索表达式分为部分基于定义的记录分布的多个搜索表达式。 针对多个搜索表达式确定目标搜索范围,使得要与多个搜索表达中的每一个搜索的记录的数量大致恒定。 多个搜索表达式在其各自的目标搜索范围内执行。 也可以通过相应的搜索范围部分地基于搜索率来确定多个搜索表达式的搜索范围。
