Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Embodiment one
The present embodiment discloses a kind of information transferring method, and the method is applied to transmitting terminal, and with reference to Fig. 1, the method can
With the following steps are included:
S101: target carrying information to be transmitted, and the original image for carrying the target carrying information are obtained.
The purpose of the application is to be designed by way of showing display end and sending visual image, realizes information
Insertion and implicit information transmission based on image visible light signal, at the same avoid insertion due to additional information and to user's
Image visual effect has an impact.
This step obtains target carrying information to be transmitted, and the original image for carrying the information first.To need
It to be inserted into the information hidden to human eye vision in the video pictures of television advertising, realizes the visible light signal for utilizing television image
For the transmission push for carrying out carrying information, it is assumed that, need to be at this when the advertisement video of certain product is played to a certain image frame
Some product informations are embedded in image frame, such as the information such as detail parameters, website or Shopping directery that can be product,
It then needs in advance before image frame broadcasting, the information to be transmitted that acquisition need to be embedded in this screen, wherein information to be transmitted can
To be expressed as string number information sequence, such as can specifically be indicated with a string of ' 0 ', ' 1 ' bit sequences.
S102: the original image is mapped as N number of subgraph, the subimage sequence of N number of subgraph composition is used for
Indicate the target carrying information to be transmitted；Wherein, the image superposition result of N number of subgraph is the original image,
The N is the natural number greater than 1.
This step is by carrying out carrying of the image procossing realization to information to be transmitted to original image, specifically, with reference to figure
2, original image A can be mapped as N number of subgraph A according to preset mapping ruler1, A2... ... AN, wherein it is described to reflect
The corresponding relationship that rule is used to indicate between carrying information and mapping result is penetrated, thus after original image is mapped as N number of subgraph
The insertion of information to be transmitted can be achieved.It should be noted that being reflected in order to not influence the normal viewing effect of display end output image
N number of subgraph A after penetrating1, A2... ... AN, i.e. A equivalent with the visual effect of original image A after time domain superposition need to be met1+A2
+ ... AN=A.
By taking intensification modulation as an example, information to be transmitted need to be specifically carried in the brightness of visible light signal by intensification modulation, base
In this, mapping obtained N number of subgraph, which can be used, in the brightness sequence of corresponding pixel area indicates information bit sequence to be transmitted
Bit value in column, for example, the brightness sequence of one group of identical numerical value, which specifically can be used, indicates bit ' 0 ', on the contrary, bright using one group
Angle value, which replaces a certain proportion of brightness sequence of increase/decrease, indicates bit ' 1 '.
To be mapped to original image if bit ' 0 ' need to be carried using the luminance information of certain pixel region
It when processing, is not required to be modulated the brightness of the pixel region, resulting N number of subgraph is mapped, corresponding to the pixel region
Brightness L1, L2... ... LNIt does not change, i.e. L1=A2=... LN=L, wherein L indicates original image in the bright of the pixel region
Degree；On the contrary, carrying out mapping processing to original image if bit ' 1 ' need to be carried using the luminance information of the pixel region
When, each subgraph need to be modulated in the brightness of the pixel region, each subgraph is made alternately to increase plus/minus in the brightness of the pixel region
Weak certain proportion, it is assumed that increase/decrease brightness ratio is 50%, then the L after intensification modulation1=0.5L, L2=1.5L, L3=
0.5L, L4=1.5L ..., to guarantee no matter send bit ' 0 ' or bit ' 1 ', the average brightness of picture, which does not change, (to be adopted
When showing each subgraph with high frame rate, human eye can not differentiate brightness flicker when sending bit ' 1 ', and it is folded can only to experience multiframe
Average brightness after adding).
Based on this, for a string of ' 0 ', ' 1 ' bit sequences corresponding to information to be transmitted, it is assumed that include in the bit sequence
Number of bits be P, then can be by the way that original image to be orderly divided into P pixel region, and successively to the bright of P pixel region
Degree is modulated, and information to be transmitted can be respectively indicated by the brightness sequence of each pixel region by making to map resulting each subgraph
0 ', ' 1 ' bit value in bit sequence, to realize the carrying to information to be transmitted.
S103: showing N number of subgraph using target frame speed, pushes the target carrying letter to realize to transmit to user
Breath；Wherein, the target frame speed supports the subimage sequence during displaying, each subgraph by after time domain superposition with it is described
The visual effect of original image is equivalent.
In foundation mapping ruler, after original image is mapped as the N number of subgraph that can carry information to be transmitted, in order to make
Communication process is not readily perceptible by the human eye, it is ensured that the normal viewing effect for not influencing display end output image is showing each subgraph
When, the duration of each subgraph need to be shortened, i.e., need to improve display end on the basis of video image primitive frame is fast and show N
The frame speed of a subgraph, it is ensured that visually equivalent with original image after the sub-image signals of each high frame rate are by time domain superposition.
And the video image for being not required to carrying additional information, then it is still shown using its primitive frame speed.
In the present embodiment, when carrying out high frame rate display to each subgraph, used frame speed numerical value is specially original graph
As N times of primitive frame speed, thus, for each original image, its achievable mapped in its corresponding display time interval
The high frame rate Overlapping display of each subgraph, by improving the display refresher rate of subgraph, using one group of subgraph at one
The high frame rate of period is sent, the display effect of equivalent corresponding period original image.
The application utilizes the persistence of vision of human eye, and practical visual effect is the time domain superposition of multiple frames in high speed, and human eye can not
Tell single high speed image frame, it is seen that superimposed image frame be original image, to realize communication process to vision
It hides.
As it can be seen from the above scheme the application method is obtaining target carrying information to be transmitted, and for carrying the mesh
After the original image of mark carrying information, image procossing is carried out to original image, stack result is mapped as and is equal to the original
N number of subgraph of beginning image, and the subimage sequence of N number of subgraph composition can indicate the target carrying to be transmitted
Information；And on this basis, use can support the subimage sequence during displaying, after each subgraph is by time domain superposition
It is shown with the equivalent high frame rate of the visual effect of original image and sends the N number of subgraph of mapped, realized and be based on implicitly may be used
