First embodiment

With reference to Fig. 2, the information transmitting apparatus module diagram that Fig. 2 is provided for first embodiment of the invention.

Information transmitting apparatus in the present embodiment include：

Generation module 21, for generating view data, described image data include N number of Frame, in N number of Frame At least one Frame be target frame, the target frame includes information to be transmitted；

Transport module 22, for by described image data output to display module；

The display module 23, for showing described image data with default refresh rate, the refresh rate is more than people's outlook Other refresh rate so that the display of the target frame is not identified by the human eye.

The information transmitting apparatus of the present embodiment can be the electronic equipment with hardware such as display module, processors, including But it is not limited to mobile phone terminal, panel computer, desktop computer, intelligent watch.Terminal unit in information transmitting apparatus are Fig. 1 When, generation module 21 can be realized by the controller 170 in Fig. 1, and transport module 22 is by Fig. 1 between device interior each unit Coffret realizes that display module is realized by the display unit in Fig. 1.

Frame is actually picture one by one, so target frame is also a frame picture, usually utilizes in picture Pattern transmission information on picture, so the information to be transmitted in the present embodiment can be deposited in a pattern in target frame Similar to pattern in 2 D code transmission information.Wherein, target frame can be the figure being directly made according to information waiting for transmission Piece, or information to be transmitted is loaded into the picture that obtains in the initial data frame for generating data.The no matter life of target frame Into mode for any, final result is ensured in target frame comprising information to be transmitted.

In the present embodiment, when information to be transmitted is simpler, only just can completely carry all of with a frame data frame Information to be transmitted；When the content that information to be transmitted includes is more, only with a frame data frame, the pattern on Frame may compare Complexity, is unfavorable for obtaining correct identification of the equipment of information to be transmitted to information to be transmitted in the Frame.At this point it is possible to by one Part information to be transmitted merotomizes, and each section is carried on respectively on a frame data frame, relative, recognizes the transmission information Equipment needs all to identify each section information to be transmitted can just obtain complete information to be transmitted.

In the present embodiment, for position of the target frame in view data does not limit, in theory for, target frame can With at an arbitrary position, because information receiver can obtain all Frames in view data in the way of with shooting.But This require information reception device is opened time of shooting and is shown with default refresh rate earlier than (typically earlier than) information transmitting apparatus The time started of view data, hence it is evident that, can be to use information dispensing device and the user of information receiver in practical application Bring certain restriction.In the epoch of this service is above everything else, only more excellent service, more users could be attracted.In order to drop Low above-mentioned restriction, generation module can select to repeat to show the corresponding data of a information to be transmitted when Frame is generated The mode of frame (frame or multiframe), the number of times for repeating can be arranged according to practical situation.

So the composition of N number of Frame of generation module generation at least includes 4 kinds of following situations：

1st, a information to be transmitted is only carried on a frame data frame, and the Frame does not repeat as target frame, only in figure As occurring once in data；Wherein, in order to improve the success rate that information receiver reads the target frame, while also reducing reading Target frame can be arranged on the time that target frame needs, generation module 21 centre position of N number of Frame, or centre is rearward Position.

2nd, a information to be transmitted merotomizes, and each section is carried on a frame data frame, carries each several part transmission The Frame of information does not repeat as target frame per portion target frame；Wherein, dress is received by information in order to increase information to be transmitted The probability of complete reading is put, target frame can be arranged on generation module 21 centre position of N number of Frame, or centre is leaned on Position afterwards.

3rd, a information to be transmitted is only carried on a frame as on the Frame of target frame, but, wrap in N number of Frame Multiple target frames are included, i.e., multiple target frames of repetition are set in N number of Frame, a letter to be transmitted is carried in a target frame Breath, the target frame for repeating is arranged on can greatly improve the acquisition success rate of target frame in N number of Frame, and reduce obtaining Required time.Wherein, the target frame for repeating can be than more uniform distribution in N number of Frame.

4th, a information to be transmitted merotomizes, and each section is carried on a frame data frame, carries each several part transmission Used as target frame, the corresponding target frame of a information to be transmitted repeats (to repeat time the Frame of information in N number of Frame Number is with being actually needed settings), substantially increase the probability that information to be transmitted is completely obtained, it is to avoid message part to be transmitted is scarce Lose.

It is apparent that latter two is more more advantageous than first two, so, generation module 21 when view data is generated, wherein Target frame can be repeated according to practical situation.

Generation module 21 is generated after the view data comprising N number of Frame, and transport module generates generation module 21 View data is exported to display module 23.It is well known that display module 23 is to refresh the picture frame for showing with certain refresh rate, The refresh rate is the number of times of image appearance each second on display module 23, and its unit is hertz (Hz).

At present, the highest refresh rate of the display device on mobile terminal is that 120HZ, i.e., one minute refresh 120 images.Its In.The refresh rate of eye recognition is 60HZ, i.e., when less than 60HZ, the image human eye of each frame can be recognized, in order to protect life Information to be transmitted in the target frame generated into module 21 so as to be not identified by the human eye, what display module 23 was used when showing Default refresh rate needs the condition for meeting the refresh rate (generally 60HZ) more than eye recognition.

Wherein, refresh rate is higher, and display module epigraph flickering is less, and stability is also higher, in other words to regarding The protection of power is also better.It is reported that, eyes of people when general, it is not easy to discover the flickering that more than 75Hz refreshing frequencys are brought, The refreshing frequency for reaching more than 80Hz is just completely eliminated image flicker and shake sense, and eyes also will not be too easily tired.It is based on Discussed above, can arrange rational refresh rate, and such as 120HZ is used for display module 23.

For display module 23, display effect may a still image, the Dynamic Graph of GIF forms, or a section regard Frequently, the present embodiment is not limited this.

For the situation for being shown as still image, generation module 21 can obtain a static state when view data is generated Picture is replicated, and target data frame forms together view data.For the situation for being shown as Dynamic Graph or video, can obtain Take with Dynamic Graph, or video is original material, and target frame is generated or in original material with the Frame in original material The mode of insertion target frame generates view data.

From the description above, can obtain, human eye typically at most recognizes the refresh rate of 60HZ, and the part more than 60HZ is Human eye None- identified, so the target frame of the present embodiment is hidden in the part more than 60HZ, human eye None- identified is effectively hidden Data to be transmitted has been hidden, the transmission security of data to be transmitted has been improve.

Simultaneously for the data to be transmitted of the present embodiment, only information receiver could be obtained using photographic head, enter one Step improves the safety of data to be transmitted.

The present embodiment provides a kind of information transmitting apparatus, and generation module can be by Information hiding to be transmitted in view data It is to refresh display image data to exceed the refresh rate of human eye refresh rate during display module display image data in target frame, it is right In target frame, the probability of eye recognition is substantially absent from, it is often more important that, for the target frame of the present embodiment, acquisition Mode is to refresh to obtain with the frequency for exceeding default refresh rate using photographic head, and information to be transmitted reaches the mistake of information acquisition device Cheng Wuxu networks are participated in, it is ensured that data to be transmitted will not be kidnapped by network, improve demand of the specific communication information to safety.

Fourth embodiment

Referring to Fig. 5, the present embodiment proposes a kind of method for sending information, addition can be hidden in the Frame of view data The target frame of information to be transmitted, during display image data, the refresh rate of Frame looked into the refresh rate of eye recognition, substantially On prevented the probability of eye recognition.Wherein, the method for sending information of the present embodiment need not use network, corresponding reception Method is again without using network, it is ensured that data message will not be kidnapped by network, with higher safety, be particularly suited for The higher communication information is required to transmission security.

The method for sending information of the present embodiment includes：

S501, generation view data, view data includes that at least one of N number of Frame, N number of Frame Frame is Target frame, target frame includes information to be transmitted；

S502, view data is exported to display module；

S503, display module are with default refresh rate display image data, refresh rate of the refresh rate more than eye recognition so that The display of target frame is not identified by the human eye.

Above-mentioned step can realize by electronic equipments such as terminals, for example mobile phone, smart phone, notebook computer, Digit broadcasting receiver, PDA (personal digital assistant), PAD (panel computer), PMP (portable media player), navigation dress The mobile terminal put etc. and the such as fixed terminal of numeral TV, desk computer etc..Display module is by the display in Fig. 1 Unit 151 is realized.

It is well known that display module is to refresh the picture frame for showing with certain refresh rate, the refresh rate is display module On the number of times that occurs image each second, its unit is hertz (Hz).

At present, the highest refresh rate of the display device on mobile terminal is that 120HZ, i.e., one minute refresh 120 images.Its In, the refresh rate of eye recognition is 60HZ, i.e., when less than 60HZ, the image human eye of each frame can be recognized, in order to protect mesh Information to be transmitted in mark frame so as to be not identified by the human eye, the default refresh rate that display module is used when showing needs to meet More than the condition of the refresh rate (generally 60HZ) of eye recognition.During the Frame of the refresh rate for being higher by eye recognition human eye institute not Can recognize, so, the transmission objectives frame in the refresh rate for be higher by eye recognition, human eye can not be recognized.

Wherein, refresh rate is higher, and display module epigraph flickering is less, and stability is also higher, in other words to regarding The protection of power is also better.It is reported that, eyes of people when general, it is not easy to discover the flickering that more than 75Hz refreshing frequencys are brought, The refreshing frequency for reaching more than 80Hz is just completely eliminated image flicker and shake sense, and eyes also will not be too easily tired.Refresh Rate can rationally be arranged according to mentioned above principle.

In practice, generating the mode of the target frame in view data includes, number to be transmitted is loaded in initial data frame According to, or target frame is generated according to data to be transmitted, as the Frame of view data.View data is generated in S501 Mode includes but is not limited to following two kinds：

First kind of way：Raw image data is obtained, raw image data includes N number of initial data frame, in N number of original number According to information to be transmitted is added at least one of frame initial data frame, the initial data frame of data to be transmitted is added with as mesh Mark frame.

Wherein, raw image data is the view data for being not added with information to be transmitted, and the view data includes N number of original Frame, selects at least one to make target frame from N number of Frame.Information to be transmitted can completely be passed by a frame data frame It is defeated, at this point it is possible to directly information to be transmitted is added in a frame data frame form a frame target frame.Information receiver passes through The target frame can obtain complete information to be transmitted.

Further, it is also possible to information to be transmitted is divided into into several parts, each section is added in a frame data frame, forms multiframe Target frame.Information receiver can obtain complete information to be transmitted by the identification to multiframe target frame.

Either complete information to be transmitted is transmitted using a frame target frame or multiframe target frame, filled for information is received Target frame all must be completely obtained for putting, for the ease of information receiver target frame is obtained, the position of target frame can set It is placed in the centre position or middle rearward position of N number of Frame.Wherein, mesh is obtained in order to further improve information receiver The success rate of mark frame, can replicate a complete corresponding target frame of information to be transmitted (frame or multiframe), specific multiple Quantity processed is arranged with demand；Or, when target frame is generated, directly generate many parts of information to be transmitted of multiframe data frame transfer.Its In, multiframe target frame period can be made to be present in N number of Frame, further, target frame is uniformly distributed in a data frame.

The second way：X target frame is generated, target frame includes information to be transmitted, and obtains raw image data, it is former Beginning view data includes N-X initial data frame, and X target frame and N-X initial data frame are combined into into view data.

Wherein, the mode for generating target frame is to generate picture as target frame according to information to be transmitted, and generating mode can be with With reference to the generating mode of Quick Response Code.A complete information to be transmitted can generate a frame target frame (X is 1), it is also possible to will treat Transmission information is divided into several parts, and each section generates a frame target frame (X is the positive number more than 1).A kind of either that generation side Formula, the information to be transmitted transmitted in target frame all only portions, for the ease of information receiver successfully target frame is obtained, can be with Position target frame being arranged in the middle of Frame.It is possible to further generate the multiframe target comprising many parts of information to be transmitted Frame, and each target frame is distributed in N number of Frame, further, target frame is uniformly distributed in a data frame.

For the target frame of the present embodiment, information receiver is only shown using the frequency collection figure more than refresh rate Show the picture data that module shows, target frame could be obtained, largely prevent the probability of eye recognition, in order to further Protect information to be transmitted not reveal, the present embodiment can with generate target frame before, treat transmission information according to default encryption Agreement is encrypted.Hereafter information to be transmitted is the information after encryption, and the mode of encryption has various, and for example, the information of transmission is 123456, it is replaced with ABCDEF etc..

For display module is with the display effect of default refresh rate display image data, according to the content on N number of Frame, Possibly still image, it is also possible to which Dynamic Graph or video, the present embodiment is not limited this.

It is contemplated that, when the information after information to be transmitted is encryption, information receiver needs to adopt and cryptographic protocol Corresponding decryption protocol could be decrypted after information to be transmitted, this require information reception device learns decryption protocol, for example, For example, the information of transmission is 123456, and to be replaced with ABCDEF, manner of decryption is to replace with ABCDEF to cipher mode 123456.Wherein, the decryption protocol can be after information receiver obtains target frame, notification reception device, it is also possible to The notification reception device before information receiver obtains target frame, it is contemplated that after the display content of scanning display module, reason Solution parses information to be transmitted and can bring user preferably to be experienced, typically, before display image data, with information receiver It is decrypted the confirmation of agreement.

In consideration of it, the present embodiment can be before S503, and the confirmation that information receiver is decrypted agreement, specifically , decryption protocol can be sent to by information receiver by wireless communication unit (Fig. 1).Or, can be by decryption protocol Picture is made, for example, makes Quick Response Code, shown using display module, information receiver obtains decryption association by scanned picture View.

It is contemplated that, when a information to be transmitted is divided into several parts, and each several part is carried respectively by a frame target frame, information Reception device need by carry each several part information target frame all identify, can just acquire complete letter to be transmitted Breath.For the ease of identification of the information receiver to target frame, in the present embodiment, in addition it is also necessary to carry out target with information receiver The negotiation of frame recognition method, so that information receiver identifies a complete corresponding target frame of information to be transmitted.Target The negotiation of frame recognition method can be before or after S503.Optionally, when the confirmation of agreement is decrypted with information receiver, It is also carried out the negotiation of target frame recognition method.

Wherein, for the ease of the identification to target frame, can (frame be more in the corresponding target frame of per part of information to be transmitted Frame) addition identification information, for example, a information to be transmitted is divided into the transmission of 3 frame target frames, and this 3 frame target frame is according to each transmission Sequencing of the information content in information to be transmitted enter rower sequence.Solved with information receiver in information transmitting apparatus During the confirmation of close agreement, can be by the corresponding all target frames of information regular and a to be transmitted of the mark sequence of target frame Sequence number notification reception device.Additionally, the present embodiment can also by the way of other are feasible help information reception device pair Completely the corresponding target frame of information to be transmitted is identified portion, and the present embodiment is not limited this.

It is well known that for human eye, after the bright thing of comparison is seen, dark object is difficult to cause the note of people Meaning.In order to be further ensured that target frame is not recognized by the user, the setting that can pass through display parameters causes the display effect of target frame Fruit is less than the display effect of non-targeted frame, after non-targeted frame is seen, the target frame poor for display effect, and the sensitivity of human eye It is very low, further prevent the probability that target frame is identified by the human eye.

Based on above-mentioned consideration, in S503, display module is included with default refresh rate display image data：

For the understanding for replacing display image data according to the first display parameters and the second display parameters, it is thus understood that according to First display parameters and the second display parameters replace the N number of Frame in display image data, and such as the first frame data frame is with the One display parameters show that the second frame data frame shows that the 3rd pin Frame is shown with the first display parameters with the second display parameters, 4th frame data frame shows with the second display parameters, by that analogy.Wherein, the second display ginseng is shown as target frame Number, then illustrate that non-targeted frame and target frame in Frame are to be spaced apart, and is target frame between two frame non-targeted frames.

Wherein, display parameters include brightness, color (tone, saturation).It is simplest, brightness ginseng in the second display parameters Number is lower than the luminance parameter in the first display parameters.The display effect for reaching is that non-target frame is bright picture, and target frame is dark figure Piece, because human eye can decline in certain hour after light stimulation to the sensitivity of half-light, so the brightness of target frame is dark having Help it to hide, further, by the color parameter for arranging target frame, target frame can be gray-scale maps (or artwork master).

When display module is with 120HZ refresh rate display image datas, view data light and dark interval shows, dark picture For the target frame in the present embodiment, because the refresh rate of eye recognition is 60HZ, the interval between bright picture is exactly 60HZ, human eye The simply bright picture of 60 frames that can be recognized, for dark picture, shows, human eye can hardly experience dark figure after brightness piece The presence of piece.

A kind of method for sending information is present embodiments provided, the view data comprising N number of Frame, N number of number can be generated It is used for transmitting information to be transmitted according at least one target frame in frame；Display module with default refresh rate display image data, Refresh rate of the refresh rate more than eye recognition so that the display of target frame is not identified by the human eye, it is often more important that, for the present invention Target frame, the mode of acquisition is to refresh to obtain with the frequency for being not less than default refresh rate using photographic head, and information to be transmitted is passed Without using communication network in defeated process, it is ensured that data to be transmitted will not be kidnapped by network, specific communication information pair is improved The demand of safety.
