The accuracy and authenticity of breath.
Fig. 1 shows the flow chart of a preferred embodiment of the method for video addition watermark of the present invention.As shown in figure 1, should
Method comprises the following steps：；
S1, the data initial address for obtaining current frame image.Preferably, step S1 further comprises, in hardware abstraction layer
（HAL layers）Data stream buffer queue in obtain current frame image data initial address.The effect of hardware abstraction layer include pair
The access of device register, the equipment addressing of bus independence, interrupt processing and reset, DMA transfer（Be one kind without CPU and
Directly from the data exchange mode of memory access data）, timer and real-time clock control, the spin lock of bottom（Spin
Lock）Synchronous, BIOS interfaces and CMOS with multiprocessor（Complementary metal oxide semiconductor）Configure internal memory.Directly by regarding
Data stream buffer queue of the frequency evidence in HAL layers, obtains the data initial address of current frame image, and real time information is implemented to adjust
Take, it is accurate, quick.
S2, the width and height for obtaining the current frame image.Video capture device can be gathered and regarded according to configuration information
Frequently, the configuration information includes resolution ratio, aperture size, time for exposure, focal length etc., transfers the current resolution in configuration information
Rate, can be to obtain the width of the current frame image（width）And height（height）, and with width（width）For transverse axis,
Highly（height）For the longitudinal axis, the coordinate plane of current frame image is set.
S3, determine watermark position to be added on current frame image.Watermark can be added in any of current frame image
Position.In one embodiment, the watermark information that adds of the present invention is visual information, for the main part of not shielded image, one
As addition the lower right corner is disposed in four corners of image, such as when watermark information be temporal information, watermark information is to set
The upper left corner is disposed at during standby model, watermark information is arranged on upper left corner etc. when being photography people's name or numbering.Certainly, this
Setting is all only illustrative rather than restricted a bit, and watermark can be arranged on to any position of image by same mode
Put.Therefore need by default setting or the artificial default position for determining to add watermark, and converted before watermark is added
For the coordinate in current frame image, set original position of the watermark information on current frame image as（StartX, startY）,
Obviously, original position（StartX, startY）With the width of the current frame image（width）And height（height）With straight
Meet relation, startX≤width, startY≤height.
S4, according to the data initial address of current frame image, the width of current frame image and height and watermark current
Position to be added obtains the data address to be stored of watermark on two field picture.The data that comprehensive foregoing three steps obtain, are obtained
The data address to be stored of watermark, the data address to be stored of watermark is set as (ppY, ppU, ppV), wherein,
ppY=pStart+width*startY+startX；
ppU=pStart+width*height+startX+startY*width/2；
ppV=ppU+1。
Here, it is important to note that the sampled data form of current frame image is YUV4 in above-mentioned steps:1:1, tool
As shown in Fig. 2 the increment each put is the width of single point character, the address of each U values and V values sets 0 row 0 row and opened body
Begin, increase 2 when even number line and even column.Each point preserves a brightness value (namely Y value), and every 4 points preserve a U jointly
Value and V values, Y0, Y1, Y8, Y9 are the Y value address of point 0,1,8,9 in Fig. 2, and U0, V8 are U values address and the V values of point 0,1,8,9
Location；Y2, Y3, Y10, Y11 are the Y value address of point 2,3,10,11, and U2, V10 are the U values address and V values address of point 2,3,10,11.
Others by that analogy, do not illustrate one by one.Sensation of such a mode image in naked eyes will not play too big change, for example, former
To use RGB (R, G, B are 8bitunsigned) model, 1 point needs 8x3=24bits,（After fully sampled, YUV is still respectively accounted for
8bit）.By 4:1:After 1 sampling, and averagely only need 8+ (8/4)+(8/4)=12bits now（4 points, 8*4（Y）+8(U)+8
(V)=48bits）, averagely each point accounts for 12bits.The thus half the data compression of image.
Except above-mentioned YUV4:1:Outside 1 sample format, sample format primarily now also includes YUV4:2:0、YUV4:2:2
And YUV4:4:4, according to its each sample format the characteristics of obtain data address to be stored, due to obtaining data address side to be stored
Formula is essentially identical with aforesaid way, will not be repeated here.
S5, the lattice information for obtaining watermark.As it was previously stated, the content of watermark for it is a variety of, it is necessary to by default setting or
The artificial default form for determining addition watermark, for example, watermark information sets it to " 2013-12-2711 when being temporal information:
22:33 ", be specially " during year-month-day-point-second ", form selectes " No. tetra- word black of Times New Roman "；Watermark information
" NIKON D100 ", it is specially " unit type " that form selectes " No. five word bluenesss of the Song typeface " to be set it to during unit type.
Preferably, above-mentioned form includes but is not limited to font, size, color, other format contents such as word space, overstriking
Etc. the part addition that can also be form.Can specifically it be adjusted as needed for the content of watermark, it is numerous to list herein.
After the content set form of watermark is turned into the character string of above-mentioned form, the lattice information of the character string, the dot matrix are determined
The determination of information can be searched directly in system character library, or be point by the character string maps by carrying Program Generating
Battle array information.
Because above-mentioned video data uses yuv format, the general format of lattice information is rgb format, when both forms not
Need to do format conversion when unified, specifically,
Y=0.299*R+0.587*G+0.114*B；
U=-0.1687*R-0.3313*G+0.5*B+128；
V=0.5*R-0.4187*G-0.0813*B+128。
S6, the video data changed with the lattice information of the watermark in the data address to be stored.According to acquisition
Lattice information, the video data changed in the data address to be stored, is most preferably changed one by one according to dot matrix order.It is foregoing
Original position of the middle watermark information on current frame image be（StartX, startY）, the dot image information is（Y,U,V）It is corresponding

The watermark added through the above way, it is possible to achieve addition watermark function of taking pictures and record a video, and can ensure to clap
According to or each two field picture of video recording on watermark information accuracy and authenticity, for example, when watermark information is temporal information, video
The time of collection can directly be transferred from video capture device, pass through the method for heretofore described addition watermark, time
Watermark is added on video data in real time, and the time change of each second is recorded in time watermark and turned into and regards
A part for frequency evidence, the time recorded in time watermark is shooting time.Because the time can change at any time, time watermark exists
Even each millisecond of each second can change, but other watermark informations can be not required to the so frequent of change, for example, photography
The name or numbering of people, it is only necessary to start one section it is new take pictures and record a video when, the information of typing needs, to determine that the section is taken pictures
Completed with video recording by the people of typing information.
