Description
Technical field：
The present invention relates to a kind of dynamic reading device of machine character read code and read method.
Background technology：
Multimedia resource is made up of video, image, sound and word, and wherein sound, the digitized record of image are all kinds of
Digital recorder, digital camera and digital video recording equipment are probably already existed, and have become multimedia core.But real meaning
Record and record that digitized word equipment development is delayed in justice, be currently being widely used duplicator, the word of scanner processing
Word for analog form processing is that nature word processing result is picture format, and third party is needed if translated into text information
Identification software is supported, and duplicator, scanner device volume are big, and processing is mostly static paper material, and processing speed is slow,
Dynamic text information can not be handled.Although hand-held scanner provides light equipment, same sweep speed recognizes mistake slowly
It is poor big（Medium there are certain requirements）It is not alphanumeric processing truly.Although bar code and Quick Response Code are several
Word mode, but contained content has certain limitations on character quantity, is more suitable for the application in static field.Quick Response Code is in TV domain
It has been applied that, but without the dynamic characteristic for playing TV.Expansion 2 D code information content will be further increased image in 2 D code and exist
Display area and make recognition time slack-off and influence picture material.
With the Dynamic Announce of a large amount of text informations on a display screen, to the digitized record of this segment word increasingly
Seem important.The current real-time record to word also rests on keyboard with processing（Uniquely）Or the mode of pen and paper.On software
Existing one-dimensional bar code scans content is mostly numeral and the no Chinese character information of letter, has length requirement to bar code and has difference
Specification limit is, it is necessary to special-purpose software identification and processing, general difference.Probe is using dynamic Laser scanning irradiation striped on hardware
Code, the principle that light-sensitive element reads reflected light is the static bar code fashion of the photosensitive element scan of dynamic, the more complicated cost of structure
It is higher.
