Embodiment
The present invention realizes the transfer of data between mobile terminal, need staggered relatively for two mobile terminal screens, the data encoding that mobile terminal will transmit is displayable form, shown successively by the screen of mobile terminal, and gather the content shown by distant terminal screen by front-facing camera, carry out the data that decoding acquisition the other side is transmitted.Mobile terminal can be the terminal that mobile phone, PAD etc. have front-facing camera and screen.
Data transmission method between mobile terminal provided by the present invention, is described to transmit data instance between two mobile phones.In advance, by staggered relatively for two mobile phone screens, preferably, as shown in Fig. 1 (B), can be staggered relatively from beginning to end, namely front-facing camera and mobile phone screen are oppositely arranged.See the flow chart shown in Fig. 2, data transmission method of the present invention comprises the following steps:
Step S1: when a user setup data sends instruction, its mobile phone shows specific announcement information by its display screen, to notify the corresponding initialization procedure of the other side's handset starting, such as, shield in vain by showing twice successively, blank screen as described announcement information, or adopts special audio information as described announcement information.
Step S2: the other side's mobile phone, by after its camera collection to described announcement information, shows same information, as feedback information by its display screen.
After step S3: two mobile phones all receive above-mentioned announcement information, then confirm to transmit data, now, two mobile phones can show the specific image of certain resolution, are gathered by the other side.When identifying, enter step S6, namely carry out coded data transmission according to respective image.
If None-identified image, then perform step S4.This step has as follows:
Described specific image represents a specific code encoding/decoding mode, collect the mobile phone of the described image of the other side's display, when correctly can identify this image, (image recognition technology is prior art, therefore repeat no more), then can feed back to the other side by an announcement information, to notify that the other side can adopt code encoding/decoding mode corresponding to this image to be shown by the image that code and decode is correspondence.
Step S4: when data acquisition side's mobile phone can not identify described image, it notifies the other side by another announcement information (as shown three screen, blank screens in vain successively), transmit leg mobile phone then uses the specific image after reducing resolution to show again, according to the method, each specific image of different resolution several times on probation from high to low, until after data acquisition side can correctly identify, notify the other side by corresponding information again, namely determine that the other side can adopt the coded system corresponding to specific image of corresponding resolution to carry out the coding display of data.If when data display side is reduced to lowest resolution, recipient still can not identify and then perform step S5.
In this step, due to different resolution image entrained by pixel quantity different, therefore, the size of the portable data volume of a sub-picture after the size corresponding data coding of resolution, the i.e. height of encoding rate.
By this step, the coded system of data receiver can be determined, and can correctly identify on the basis of image guarantee recipient, data receiver is made to adopt the image of high-resolution as much as possible, namely coding is adopted to make image carry as far as possible multidata coded system, i.e. comparatively high code-rate.Simple example, the i.e. portable information of 1024*768 pixel (use black, white expression 0,1 information as the most simply, and data can correspond to 0,1 different information), must be more than the portable information of 800*600 pixel.Specifically how to be encoded to image (as being encoded to image in 2 D code, bar code image), be known technology, also non-invention paid close attention to, and repeats no more.
It should be noted that, transmit leg can be different from the coded system of recipient, as long as the coded system of transmit leg is corresponding with the decoding process of recipient.Such as, the pixel that two mobile phone cameras are supported is different, or screen resolution is different, thus, a mobile phone may be formed and use high-definition picture exhibiting data information, and another mobile phone uses low-resolution image exhibiting data information.
Wherein, it is suitable that step S3 to step S4 friendship is applicable to two mobile phone distance, front-facing camera can normally be focused the image after the data encoding gathering the other side screen shows, to realize based on can in focusing situation, data encoding is adopted to be the transfer of data of image, this mode, because every sub-picture all can carry a lot of data, therefore transfer of data is fast.
Step S5: when data receiver determines to collect suitable images, it notifies the other side by another announcement information (as shown four screen, blank screens in vain successively), after transmit leg mobile phone receives this announcement information, adopt lightness, black and white replaces, vitta rolling etc. does not need data receiver's camera focusing and collectable mode coded data, and shown accordingly by screen, received by data receiver.
Step S6: carry out coded data transmission according to respective image.
Wherein, only when data receiver can correctly identify, notify the other side by corresponding announcement information, determine adopted coded system to make data receiver mobile phone.
This step is excessively near corresponding to two mobile phone distance, and front-facing camera cannot normally be focused, and cannot collect image clearly, or hypertelorism, also cannot collect transfer of data when enough images clearly.
Concrete data how to correspond to lightness, black and white alternately, vitta rolling etc., also non-invention focal point, repeats no more.
Below, then with a concrete example, said method of the present invention is described further: as shown in Fig. 1 (A), Fig. 3, when carrying out transfer of data, the mobile terminal of data receiver, by image acquisition units 20, as camera, gathers the image shown by another mobile terminal.In image acquisition process, two mobile terminals are placed upside down as shown in Fig. 1 (B), gather image shown by another mobile terminal screen 70 to make image acquisition units 20.
When two mobile terminals by distance detecting unit 10 detect its distance be therebetween less than 50mm time, image acquisition units 20 cannot realize accurate focusing, only can the strong and weak and color of sensing light change.Or, when the distance between two mobile terminals is greater than 100mm, the imaging although image acquisition units 20 can accurately be focused, due to hypertelorism, the too small None-identified of image of collection, but can sensing light power and color change.As shown in Figure 4, the image gathered comprises the one direction light intensity gradual change of being irradiated generation in Fig. 4 (A) by single light source, and the image that light intensity spreads or light intensity is shunk being irradiated generation by multiple light courcess that Fig. 4 (B) illustrates.In addition, as shown in Figure 5, the image gathered comprises the color consecutive variations that Fig. 5 (A) illustrates, and the color interval change that Fig. 5 (B) illustrates, inserts blank screen as interval between different colours.
When distance between two mobile terminals is greater than 50mm and is less than 100mm, image acquisition units 20 just can accurately be focused imaging.The image gathered comprises figure, word and Quick Response Code.Described figure comprises the combination of rectangle, circle, triangle, trapezoidal and above-mentioned image, and described word comprises 52 upper and lower case letters and 10 numerals.
The image information that mobile terminal is gathered by its image identification unit 30 recognition image collecting unit 20.Specifically, when image acquisition units 20 gather as black and white image time, then every 6 is one group by image identification unit 30, adopts binary expression character.Such as " 0 " represents white, and " 1 " represents black, then 000001=A, 000010=B, by that analogy.
When image acquisition units 20 gather as coloured image time, then every 3 is one group by image identification unit 30, the quaternary is adopted to express a character, such as " 0 " represents red, and " 1 " represents yellow, and " 2 " represent blue, " 3 " represent green, then red Huang=001=A, red blue Huang=021=B, red greenish-yellow=031=C, by that analogy, repeat no more.
Such as, or can be also one group by every 2, adopt octal system to express a character, " 0 " represents red, " 1 " represents yellow, and " 2 " represent blue, and " 3 " represent green, and " 4 " represent orange, then reddish yellow=01=A, blood orange=04=B, Blue Curacao=24=C, by that analogy, repeat no more.The color that current color/graphics can show is more than 65536 kinds.And the discernible color of image identification unit 30 is also more than 65536 kinds.So select 8 kinds of colors to carry out applying there is not technical problem under the prerequisite ensureing Absorbable organic halogens difference different colours.
When image identification unit 30 carries out colour recognition, realize, such as, by comprising the circuit realiration that model is SPCA563B chip by colour recognition chip.SPCA563B chip provides 8 cmos image sensor interfaces of 320 × 320, there is Automatic white balance and obtain state modulator function, there is color of image correct and image Gamma calibration function, there are 7 kinds of color filtering functions, there is good noise decrease and filter, size and the position of at least 21 target objects can be detected in piece image, and its result is deposited in the RAM embedding its chip internal.In addition, the image identification function of image identification unit 30 is also that TCS230D colour recognition chip realizes by model, and concrete mode repeats no more.
In addition, for graph image, alphanumeric images and image in 2 D code, its different images expresses different information, and image identification unit 30 is by identifying that above-mentioned image completes acquisition of information.For example, identification for image in 2 D code realizes by Quick Response Code decoding chip, and realizes by image recognition chip the identification of graph image and alphanumeric images, and above-mentioned technology is prior art, realize by existing chip circuit, repeat no more.
The data encoding that the main control unit 40 of mobile terminal may be used for sending be the picture format that can show to be shown by screen, and carry out the adaptive coding of resolution.
In addition, in data transmission procedure, except the announcement information adopting different screen to represent each stage can be adopted in said method, other modes can also be adopted, such as, control mobile terminal loud speaker 60 and play specific audio frequency to point out the other side.Specifically, before information interaction and after terminating alternately, whether what control loudspeaker 60 was play has or starts alternately without feeding back; And in reciprocal process, the process that alternative sounds represents transmission play by control loudspeaker 60.
Further, mobile terminal is also by loud speaker 60 and sound collection unit (not shown) transmit audio information mutually between two, and described audio-frequency information obtains by microphone 80 collection, or is pre-stored in the memory cell (not shown) of mobile terminal.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.In other words, in the scope not departing from purport spirit of the present invention, suitable change can be carried out to above-mentioned execution mode.
