    • An information processing system automatically identifies the page of a book, notebook, flip chart, writing pad, or the like. The system uses an optical sensor to read an identification code printed on each page (and the cover) of the book and processes the code to determine identifying information (e.g., page number) for the page. The optical sensor and related components are adjacent to the book and operate unobtrusively, yet reliability, at a distance therefrom. The system, which uses ambient light and selectively activates its own light source, is capable of operating under variable lighting conditions and requires no manual intervention by the user. In addition, the system is reliable and robust in that it allows standard printing techniques to be used to print the identification code on each page of the book.
    • 信息处理系统自动识别书籍,笔记本,活动挂图,书写板等的页面。 该系统使用光学传感器来读取打印在书的每一页(和封面)上的识别码,并处理该代码以确定页面的识别信息(例如,页码)。 光学传感器和相关部件与本书相邻,在远离其距离的情况下运行起来非常显着,可靠。 使用环境光并选择性地激活自己的光源的系统能够在可变照明条件下操作,并且不需要用户的手动干预。 此外,该系统是可靠和坚固的,因为它允许使用标准打印技术在书的每一页上打印识别码。
