Refering to Fig. 1-5, to meet the schematic flow sheet in one embodiment of the present invention, this method includes：
Step 101：A picture is read, the picture is converted into predetermined storage format from currently stored form, obtains institute
State the watermark Adding Area of picture；
In one embodiment of the present of invention, the process of watermark is added on specified picture：
Generate the watermark prestored：Mainly by the way that the picture of watermark is converted into depositing with yuv data form
The character types of storage.
For yuv format has two major classes：Planar and packed.
For planar yuv format, the Y of first Coutinuous store all pixels point, and then storage all pixels point U,
It is followed by the V of all pixels point.
For packed yuv format, the Y of each pixel, U, V are continuous friendship * storages.
The yuv data form of the present embodiment is specially：(preceding 8 bytes storage picture size, intermediate storage pictorial information,
Alpha value information is deposited below).
Similar with BITMAP, YUV is also a kind of colour coding method, is mainly used in television system and analog video neck
Domain, it separates monochrome information (Y) with color information (UV), and no UV information can equally show complete image, only
It is black and white, such design solves the compatibling problem of colour television set and black-and-white television well.Also, YUV unlike
BITMAP requires three independent vision signal simultaneous transmissions like that, and few frequency range is taken so being transmitted with YUV modes.
Specifically, and then to character types obscured with being split, each section of character types is finally mapped as one
Section code is used for representing each watermark, is stored in the storage of smart machine or a webserver.
Because the picture of file format also needs to the efficiency of transformer effect watermarking, therefore directly carry out table using YUV characters
Diagram piece, caused YUV pictures are referred to as " sketch ".Mainly by using conversion program software to designated pictures in the present embodiment
Different types of YUV pictures are produced into, while the size of YUV pictures can be changed by changing some parameters.Therefore operating
During be the size that can control sketch, but be again converted to artwork to not influence to the addition of the sketch after watermark
When picture quality etc., it is preferable that select not changing the size of sketch i.e. artwork in varied situations.
By the way that each section of sketch is mapped into one section of code, then code is added to original application software code
In, pass through an algorithm application program for realizing addition watermark.This method describes each section using one-dimension array, uses
Each element (a such as byte) describes a character in this part in array.
The mode that the storage format of YUV code streams samples with it in fact is closely related, and the sample mode of main flow has three kinds,
YUV4：4：4, YUV4：2：2, YUV4：2：0, its principle is that each pixel is reduced from code stream according to its sample format
YUV values, because only that correctly reducing the YUV values of each pixel, it could be extracted by YUV and BITMAP conversion formula
Go out the BITMAP values of each pixel, then show.
But so array may be very big, search and positioning sketch in each pixel when can consume longer
Between.Therefore, the sketch can be now divided into a part for picture one by one, then the picture of this each section is used into more numbers
Group describes, and reuses a data structure to preserve the relation between these arrays, this improves conversion picture and is referring to
The efficiency of addition watermark is put in positioning.
In the present embodiment, the storage mode of YUV code streams, and with the YUV for sampling each pixel behind storage mode
The method of data, wherein, Cb, Cr implication are equal to U, V.
Using YV12, YU12 forms (belong to YUV420)
YU12 and YV12 belongs to YUV420 forms, and a kind of Plane patterns, and Y, U, V component are packed respectively, deposited successively
Storage.The yuv data extraction of each of which pixel follows the extracting mode of YUV420 forms, i.e. 4 Y-components share one group of UV.
In YUV420, a pixel a corresponding Y, a 4X4 corresponding U and V of blockage.For all
YUV420 images, their Y value arrangement is identical, because only that Y image is exactly gray level image.YUV420sp with
Their the UV arrangements of YUV420p data format are entirely different in principle.420p it be after first U has been deposited, then to deposit
Put V, that is to say, that UV they be continuous.And 420sp it be UV, UV so alternately deposit.
Step 102：Watermark to be added is obtained, according to the positional information of the watermark Adding Area, by the water to be added
Print is added to the watermark Adding Area；
Add a watermark in designated pictures：
By during the code insertion of above-mentioned watermark to application program, it is necessary to ensure that all watermark codes can be performed,
Otherwise the watermark that can not be extracted in internal memory is compared.The present embodiment devises an insertion method based on event, this method
Ensure the execution route of operation by obtaining one, and watermark code is inserted into the path.
It is determined that the position that watermark is added in needing to add the picture i.e. sketch of watermark is specified by a smart machine
Incoming event adds the positional information of watermark to obtain in designated pictures, and the incoming event can include：Click on the figure specified
One position of piece, then after having responded the event, application program obtains phase of the position of the addition watermark in the designated pictures
To positional information, its position coordinates will be obtained in the content of the corresponding yuv data form of positional information, by the location point
Yuv data fmt chunk up and down chooses the basic block being only performed once as basic block, in the content of the basic block with
The machine transplanting of rice enters the yuv data form of watermark.In practice, the position can not necessarily be accurate to each pixel, due to
The picture size opened in smart machine is limited, therefore the watermark location can only be a substantially accurate position.Due to specifying
The storage format of picture and the storage format of watermark be all yuv data form, its realize principle be also in specified picture
Yuv data form data structure in find addition watermark position corresponding to yuv data form, then opened from the position
One group of yuv data form is substituted for the yuv data form of watermark by the beginning, and certain the present embodiment also supports user to add simultaneously
Enter customized information, the addition of corresponding watermark is realized using application program.Compared with program is added in existing watermark, intelligence
Energy appliance applications are more by event-driven.A system of the present embodiment according to defined completion in the application program of smart machine
Row sequence of events obtains corresponding addition information, corresponding watermark information then is added into designated pictures according to input as input
Information in.
Step 103：The picture is reduced to the currently stored form and preserved；
After watermark addition is completed, specified picture is re-converted into original form, i.e. the form before addition.Should
Process can be realized by an existing mode, for example, yuv forms are converted into jpeg format using FFmpeg instruments.
Describe to realize the mobile terminal of each embodiment of the present invention referring now to accompanying drawing.In follow-up description, use
For represent element such as " module ", " part " or " unit " suffix only for be advantageous to the present invention explanation, itself
Not specific meaning.Therefore, " module " can be used mixedly with " part ".
Refering to Fig. 6, to meet the adding set of picture watermark of the present invention, can be realized by an adding set 10, at this
In adding set, including：10- adding sets, 20- read modules, 30- modular converters, 40- add modules
Read module 20：
In one embodiment of the invention, its will be read and specific believed after specified picture and the loading of watermark picture
Breath.Specifically, the pixel value of each picture region in multiple picture regions is obtained.Obtain each picture region in multiple picture regions
The gray value of each pixel in domain.Obtain in Target Photo in multiple picture regions the pixel value of each picture region and every
The gray value of individual pixel, in order to calculate the average of the gray value of each picture region in multiple picture regions.
After the pictorial information specified of above-mentioned acquisition, the piecemeal to specified picture is mainly carried out by pixel value
Processing.It is pre- according to the pixel value of specified picture and first when the pixel value of specified picture is more than the first presetted pixel value
, accordingly, will when above-mentioned difference is more than a second presetted pixel value if the difference of pixel value carries out the division of picture region
The second above-mentioned quantity multiplies 1, i.e., picture is divided into the block of the 3rd quantity, wherein second number of the value of the 3rd quantity equal to one times
Amount.When above-mentioned difference is more than two the second presetted pixel values, accordingly, the second above-mentioned quantity is multiplied 2, i.e., is divided into picture
The block of 3rd quantity, wherein the value of the 3rd quantity is equal to twice of the second quantity.By that analogy, the pixel value for the picture specified is got over
Greatly, the picture region for the picture division specified is more.Specified picture is divided into multiple picture regions to be advantageous to calculate respectively
The variance of the gray value of multiple picture regions, the color stability in each region in multiple picture regions can be preferably analyzed,
And then the Adding Area of watermark is caused not impact the influence of user's viewing effect to target image.
Modular converter 30：
In one embodiment of the invention, specified picture is changed to the picture of a yuv data form, obscures and divides
The picture of the yuv data form is cut, the picture of each section data format of segmentation is mapped as one section of storage format, by every section
A fragment of the storage format as picture, form picture code.Meanwhile store a series of watermark figures that can be used for addition
Piece, the watermark picture are also stored using the yuv data form.The yuv data form of the present embodiment is specially：(preceding 8 bytes
Deposit picture size, intermediate storage pictorial information, behind deposit alpha value information).The watermark of the present embodiment uses picture,
But need to be changed picture unprocessed form, that is, the picture profile of a yuv data form is produced, and in order that obtain watermark
Effect is more preferable, also needs to merotomize profile, and different piece will share some redundancies.In this way so that should
Watermark is difficult to be changed, even if a part of watermark is altered, still may determine that watermark in application program whether with user
What is provided is identical.In addition, this method can automatically generate the pattern of some storage formats, conversion lattice are dynamically arranged in internal memory
Picture after formula, if representing watermark using multiple profiles, each section in the profile both corresponds to the one of storage format
Individual fragment.
Add module 40：
The incoming event specified by a smart machine adds the positional information of watermark to obtain in designated pictures, and this is defeated
Incoming event can include：The position of picture specified is clicked on, then after having responded the event, application program obtains the addition water
Relative position information of the position of print in the designated pictures, by the content of the corresponding yuv data form of positional information
Its position coordinates is obtained, using the yuv data fmt chunk up and down of the location point as basic block, chooses what is be only performed once
Basic block, the yuv data form of the radom insertion watermark in the content of the basic block.In practice, the position is not one
Each pixel is surely accurate to, because the picture size opened in smart machine is limited, therefore the watermark location can only be
One substantially accurate position.Because the storage format of specified picture and the storage format of watermark are all yuv data forms, its
The principle of realization is also to be found in the data structure of the yuv data form of specified picture corresponding to the position of addition watermark
Yuv data form, then one group of yuv data form is substituted for the yuv data form of watermark since the position, this certain reality
Applying example also supports user to add customized information simultaneously, and the addition of corresponding watermark is realized using application program.
Compared with program is added in existing watermark, smart machine application program is more by event-driven.The present embodiment is according to smart machine
The sequence of events sequence of defined completion in application program obtains corresponding addition information, then according to defeated as input
Enter and add corresponding watermark information in the information of designated pictures.
The present embodiment can also verify whether watermark is identical by startup optimization smart machine application program, and scanning intelligence is set
The storage device of standby application program, and watermark is positioned from storage device, then extract the relevant information of watermark and carry out checking watermark
Yuv data form.When needing to verify the watermark of application program, extracted first from application program, then scan internal memory
And obtain watermark.After watermark is extracted, itself and the watermark that user provides are compared, if identical, certifying software be by
Restructuring.It should be added that do not need two watermarks identical in the present embodiment.Therefore, though picture some
Part is damaged, and compare instrument by human eye or text is compared to YUV similitudes, and then identifies watermark, to protect user
Identification information.
After watermark addition is completed, specified picture is re-converted into original form, i.e. the form before addition.Should
Process can be realized by an existing mode, for example, yuv forms are converted into jpeg format using FFmpeg instruments.
