Description
technical field:
the present invention relates to a kind of dynamic reading device and read method of machine character read code.
background technology:
multimedia resource consists of video, image, sound and word, and wherein the digitized record of sound, image is that all kinds of digital recorders, digital camera and digital video recording equipment exist already, has become multimedia core.But truly recording and record digitized word equipment development lags behind, the word that current widely used duplicating machine, scanner are processed is that the word that analog form is processed is that natural character word processing result is picture format, need the support of third party's identification software if convert Word message to, and duplicating machine, scanner device volume are large, what process is mostly static paper material, processing speed is slow, can't process dynamic Word message.Although hand-held scanner provides light equipment, the same slow identification error of sweep velocity large (medium be there are certain requirements) is not alphanumeric processing truly.Although bar code and Quick Response Code are digital forms, contained content has certain limitation on character quantity, is more suitable for the application in static field.Quick Response Code is applied at TV domain, but does not bring into play the dynamic perfromance of TV.Enlarging 2 D code information content will further increase image in 2 D code at display area and make recognition time slack-off and affect picture material.
dynamic demonstration along with a large amount of Word messages on display screen, more and more seem important to the digitized record of this segment word.The current real time record to word with process the mode also rest on keyboard (unique) or pen and paper.On software, existing one-dimensional bar code scans content is mostly that numeral and letter do not have Chinese character information, and bar code is had length requirement and the different specification restriction is arranged, and needs special software identification and processes, general poor.On hardware, scanner head adopts dynamic Laser scanning to irradiate bar code, and it is that the dynamic optical photosensitive elements scans static bar code mode that light activated element reads catoptrical principle, and the complicated structure cost is higher.
