Background technology
The real-time dynamic process technology of mobile terminal video signal, traditional processing mode is: the signal of gathering is deposited this locality earlier, add special efficacy on the ground or handle local signal at this again, output to display unit after finishing dealing with again.The shortcoming of above-mentioned processing mode is: the exchanges data of GPU module and internal memory is a very big expense, will allow GPU resume module timeliness promote greatly if can reduce the expense of this part on the whole.The reason that causes is: from the characteristics of GPU module execution, each thread all reads the data block of a block length alone from internal memory, write back to after encryption is finished in the internal memory, block length of every like this encryption all will be read and write internal memory one time, causes whole IO efficient low.
The utility model content
The technical problems to be solved in the utility model provides the real-time dynamic treatment device of a kind of mobile terminal video signal, solve all portable terminals in the past and can not handle the problem of acquired signal in real time, and utilization GPU module is carried out high-speed concurrent operation, simultaneously can load various special efficacys, ageing, the promptness of signal processing are promoted greatly, also fully call mobile terminal device and carried out computing, realized " physics acceleration ", be better than carrying out the conventional process mode of " soft acceleration " greatly with the CPU module.
For solving the problems of the technologies described above, the utility model is achieved through the following technical solutions: the real-time dynamic treatment device of a kind of mobile terminal video signal, comprise video acquisition device, CPU module, GPU module and display unit, the output of described video acquisition device is connected with the input of described CPU module and the first input end of described GPU module respectively, the output of described CPU module is connected with second input of described GPU module, and the output of described GPU module is connected with described display unit.
Further preferred version, described video acquisition device is the shooting unit.

Fig. 2 is the workflow diagram of the real-time dynamic treatment device of the utility model mobile terminal video signal;
Among the figure: 1-video acquisition device, 2-CPU module, 3-GPU module, 4-display unit.
Embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
As depicted in figs. 1 and 2, the real-time dynamic treatment device of a kind of mobile terminal video signal comprises video acquisition device 1, CPU module 2, GPU module 3 and display unit 4.Described video acquisition device 1 is the shooting unit, and described display unit 4 is a LCD display.The output of described video acquisition device 1 is connected with the input of described CPU module 2 and the first input end of described GPU module 3 respectively, the output of described CPU module 2 is connected with second input of described GPU module 3, and the output of described GPU module 3 is connected with described display unit 4.
After video acquisition device 1 of the present utility model is obtained acquired signal, this signal is written in the GPU module 3 in real time, here the portable terminal processing mode with traditional is different, traditional portable terminal directly gives CPU to carry out computing signal, can't promote it like this and carry out efficient, simultaneously can't load special efficacy dynamically, and the utmost point is not smooth yet to output to the display device picture effect yet.Therefore the utility model is written to signal in the GPU module 3 in real time, adopts the mode of GPU module 3 parallel computations that signal is carried out high-speed computation.The signal data that is written to GPU module 3 is when carrying out parallel computation, also load special efficacy (OpenGL writes), and have only carry out computing by GPU module 3 just can fast processing, if give CPU module 2 to carry out this processing, its ageing will reduction greatly, the picture signal that spreads out of is not smooth with the utmost point yet.
In the utility model, GPU module 3 is display card " hearts ", also just is equivalent to the effect of CPU in computer, and it has determined most of performance of calculating, also is the differentiation criterion of 2D display card and 3D display hardware simultaneously.The 2D display chip mainly relies on the disposal ability of CPU when handling 3D rendering and special efficacy, be called " soft acceleration ".The 3D display chip is that 3-D view and special effect processing function are concentrated in the display chip, also promptly so-called " hardware-accelerated " function.And the utility model is fully brought the efficient of " hardware-accelerated " into play exactly, carries out computing by GPU module 3, in the process of computing, just dynamically special efficacy is loaded on the signal, finishes the fusion treatment of signal and special efficacy, and process as shown in Figure 2.
Innovation key point of the present utility model has:
(1) the real-time acquisition process graph image of GPU: existing portable terminal is to collect this locality earlier to be handled to the processing of graph image again, and is not real-time, and the utility model promotes the ageing of image transmission to greatest extent.
(2) the GPU real-time Transmission shows: conventional art can't be realized real-time processes and displays, and it is very not smooth to load picture in real time, and the utility model can be handled and transmit in real time, and picture is very smooth.
The utility model mainly has following advantage:
(1) use the GPU dynamic acquisition to handle
The traditional mobile terminal video signal collective can't be realized dynamically, handle in real time, normally stores this locality earlier into, adds the effect of processing, and then transmission, and the utility model uses the GPU technology, does not need to store image into this locality, directly handles in the enterprising action attitude of the vision signal of gathering.
(2) use GPU real-time Transmission signal
Conventional art is to handle with CPU, and its real-time is poor, and the utility model is handled transmission signals by GPU, has promoted real-time greatly.
(3) the GPU concurrent operation promotes the picture smoothness
Traditional mobile terminal is if add special efficacy when showing acquired signal in real time, and picture effect will be very not smooth, can effectively address this problem by the utility model.
Need to prove at last; the above only is preferred embodiment of the present utility model; rather than to the qualification of technical solutions of the utility model, any the utility model technical characterictic being equal to of being done replaced or corresponding improvement, still within protection range of the present utility model.
