Description
Technical field
The invention belongs to digital video image treatment and display technology field, it is related to a kind of OSD (OnScreen
Display, screen display) realization method and system.
Background technology
In the utilization of multimedia digital image processing techniques, video detection system is often the emphasis of concern.Conventional
Video and graph compound method has two kinds：
1) it is overlapped using chip superposed
2) pixel is calculated using counter to be overlapped
Both approaches may be only available for being superimposed simple characters, it is difficult to complex figure is supported, therefore the information content that OSD is included
It is few.And character can be completely covered the information of original video image when imaging importing is carried out, the regulation of transparency is not supported, no
Can be adapted to according to the change of video additive fusion scene.Other both approaches need the complicated periphery of configuration when in use
Circuit, such as character font dot matrix memory.Hardware circuit design is more complicated, in-convenience in use, stability it is poor and most
OSD can not be edited.Each character used in OSD is also required to carry out dot matrix description in advance and additional space is stored,
Maintenance management high cost.
The present invention is merged using the pixel-level image data investigation of ARGB color spaces, can solve problem above.Form
For the color of the single pixel of the video image of ARGB is 32 place values：Alpha, red, green and blueness are each 8.Storage exists
Alpha value in Alpha passages indicates the transparency of color, represents the mixability of color and background colour.I.e. one pixel
Transparency can be considered as the stochastic variable of interval [0,255], wherein 0 represents fully transparent color, 255 represent completely impermeable
Bright color.Data operation directly is carried out to the pixel in image, the imaging importing fusion of Pixel-level is realized.Given source color
Three components (red, green and blue) all mix with the respective component of background color according to below equation：
Show Color=source color × alpha/255+ background colors × (255-alpha)/255
The content of the invention
The present invention provides a kind of adjustable video and graph compound method and system of transparency based on OMAP chips, it is intended to solve
Certainly existing OSD implementation methods editor very flexible and development cost problem high, it includes following:
User's operation module, acquisition module, memory module, ARM control modules, DSP operation module and display module.User
Select to want the picture and its transparence value of Overlapping display by the interactive interface of user's operation module, by the pretreatment of OSD pictures
The buffering area of memory module is write afterwards, and OMAP chip ARM control modules acquisition module obtains the real time video data of specific format,
Real time video data and image data are carried out OMAP chip DSP operation modules the weighting of Pixel-level according to the transparence value of setting
Calculate, display module shows final additive fusion effect by LCD screen.Wherein totally 256 grades of mixed transparent angle value support 0~255
Regulation.
Specifically, acquisition module uses CCD camera and TVP5146M2 decoding chips, in the form of frame buffering queue
Obtain the video data of yuv format.
Specifically, ARM control modules and DSP operation module are communicated by DSPlink, share SDRAM data buffer zones.
The present invention by the operational capability of DSP, the characteristics of it takes full advantage of spatial domain treatment and calculates simple, it is to avoid frequency
The complex process of domain treatment, is superimposed the whole additive process and picture selected by user of transparent OSD on real-time video
Complexity is unrelated, supports the real time modifying of mixed transparent degree, improves flexibility and the convenience of OSD.

Fig. 2 is test OSD pictures omap.rgb；
Fig. 3 is the video image of a frame Real-time Collection；
Fig. 4 is the effect 1 of video image and test pictures additive fusion；

Specific embodiment
The present invention is further described with example below in conjunction with the accompanying drawings
The OSD pictures that user is superimposed needed for being selected under the current directory of program by interactive interface, and set overall mixed
Transparence value parameter alpha is closed, wherein number range is (0~255), totally 256 grades.Selected OSD image datas can be added
Be downloaded to OSD windows, and recordable picture width parameter i and height parameter j.
Wherein real time video data transparence value is alpha, and OSD pictures transparency is 255-alpha.Reference can be made to Fig. 2, one
It is the test pictures of 400x272 to magnify small, for real time video image additive fusion, can therefrom find out that OSD test pictures are
Complete nontransparent picture, transparence value is defaulted as 255.
The performance parameter of camera device is obtained, the standard of collection video image is read and is recorded the yuv video figure of collection
The specific storage format of picture, picture traverse parameter m and picture altitude parameter n.Core is decoded by CCD camera and TVP5146M2
Piece obtains real time video data, reference can be made to Fig. 3 is when not being overlapped fusion, the frame video image taken by camera,
Its size is 720x576, and the transparence value of the image is defaulted as 255, i.e., nontransparent.
The frame buffering queue of OMAP chip ARM control modules control real time video data collection, the yuv format reality for collecting
When video data can be transferred to DSP operation module.
Specific storage format (such as 4 of the DSO computing modules according to yuv video data:4:4 or 4:2:2 etc.), select different
Single frame video data are transformed into ARGB color spaces by DSP algorithm, and video data is loaded into video window.Wherein solid color
The result of calculation value of passage if more than 255 when if be set to 255, if result of calculation value be less than 0 if be set to 0.Wherein according to journey
The alpha value that sequence is input into when starting, all pixels point to single frame video image carries out transparence value setting.
So that YUV422 is converted to ARGB as an example:
ARGB (m, n)=alpha (m, n)+R (m, n)+G (m, n)+B (m, n)
Wherein ARGB (m, n) is m rows in a frame ARGB images, the pixel value of the n-th row
Alpha (m, n) is m rows in a frame ARGB images, the transparence value of the n-th row
1) conversion of R Color Channels
R (m, n)=[1192* [YUV (m, n) -16]+1634* [YUV (m, n+3) -128]]>>10
2) conversion of G Color Channels
G (m, n)=[1192* [YUV (m, n) -16] -833* [YUV (m, n+3) -128] -400* [YUV (m, n+1) -128]
>>10
3) conversion of B color channel
B (m, n)=[1192* [YUV (m, n) -16]+2066* [YUV (m, n+1) -128]]>>10
Last OSD windows and video window are overlapped display, are connected with LCD screen by DVI output interfaces, can be direct
Observation additive fusion effect, after having shown a frame video image, is reentered into rear of queue, and take from queue heads by current frame buffer
Go out new frame buffering, carry out the Overlapping display of next frame video image, until stopping collection image.The wherein pixel of overlap-add region
Point value can be weighted mixing according to video image and the respective transparence value of picture, and non-superimposed region then directly displays original
Video image.Single pixel after to additive fusion is calculated as follows:
Display data=video data × alpha/255+OSD pictures × (255-alpha)/255
Additive fusion region:
Non-superimposed integration region:
Fig. 4, Fig. 5, Fig. 6 are the treatment effects of this algorithm under different alpha input values, it can be seen that after fusion superposition
Image it is fine while remain the image information of video image and test pictures, do not cause image fault or fuzzy.
Technical characteristic of the present invention without description can be realized by or using prior art, will not be repeated here.Certainly
Described above is not limitation of the present invention, and the present invention is also not limited to the example above, the ordinary skill people of the art
Change, addition that member is made in essential scope of the invention, should also belong to protection scope of the present invention.
