摘要

The method involves positioning a digital camera i.e. web cam, before a numerator, and recording a tally counter with interesting information. Text recognition/image analysis is executed when processing of recognized numerator data is necessary. The digital camera is integrated or coordinated with a mini-computer or miniaturized computer. Frames are received by the web cam at predetermined time intervals. The numerator data is transmitted through a cable and a wireless local area network (WLAN) or via Internet.
