Abstract
The invention relates to an audio-frequencizing image capture device that uses image capturer and processor to digitalize the image signal, then change the digital image data into audio signal. Thus, the audio terminator of mobile phone can be used as the input port, when the audio signal is demodulated the mobile phone can gain the image data and display on the screen. Moreover, the mobile phone with audio image data can transmit the signal to any long-distance mobile phone by any mobile communication system. Thus, the function of using the wire or wireless audio channel to transmit digital image data is realized.
Description
Technical field
The present invention is a kind of audio frequency image capture unit, refer to especially a kind of can be with the signal of video signal audio frequencyization, and must see through wired or wireless voice channel and be sent to image capture unit in the mobile phone.
Background technology
In the recent period mobile phone by the 2nd generation, the 2.5th generation go so far as the 3rd generation communication system, and just stride forward towards the 4th generation at present.
Wherein communication system all adds the transmission of digital package the 3rd generation of the 2.5th generation in the wireless telecommunication system that conversation originally only is provided, only, the 3rd generation communication system technology comparatively ripe.For in the 3rd generation communication system comparatively the digital package transmission technology known of common people be WAP/GPRS.
In fact,, therefore, can develop the digital communication platform under it separately, and cause and each other communication system and incompatible because each tame system dealer respectively has its communications protocol of following.Letter says to have only the function of using the identical systems dealer that interior biography mutually of net or network download just can be provided at present, releases the action description project that is established in the GPRS agreement as domestic TWM.
Owing to transmit the required frequency range of numerical data much larger than voice signal, so can take frequency range bigger in the system.Therefore, the digital delivery service that just present each tame communication system operator provides, its expense of asking for is higher than call rate concerning the mobile phone holder.
As shown in the above description, if want between two mobile phones in real time to passing data as digital photo, then certainly will see through the Mobile Communications system just can reach, or reprint to world-wide web, see through world-wide web and be sent to remote terminal, could show after the terminal downloads that connects world-wide web by remote handset again.That is can not reach the purpose that real-time transmission shows, simultaneously owing to necessary digital channel by the wireless telecommunications dealer, so necessary defrayment, and then the trouble and time-consuming that seems.
Summary of the invention
For this reason, the present invention provides a kind of audio frequency image capture unit, make mobile phone receive the audio frequency signal of video signal of exporting by the audio frequency image capture unit by voice channel, and in addition after the demodulation show image on screen, again, reception has the mobile phone of audio frequency signal of video signal can be by dialing remote handset, the audio frequency signal of video signal is directly seen through radio speech channel be sent to remote handset, make the holder of this mobile phone need not to apply for digital transmission channel to the dealer of system, transmit expense and can save data channel, so be a quite practical invention creation.
Desiring to reach the employed major technique means of above-mentioned purpose, is to make the audio frequency image capture unit include:
