Embodiment
Below in conjunction with accompanying drawing 1, provide preferred embodiment of the present invention, in order to describe technical scheme of the present invention in detail, but protection scope of the present invention is not limited to subordinate's embodiment.The present invention, by technical scheme realization once, comprises the steps:
Step 1, image capturing system gathers the picture that subsystem output occurs at display control program interface, and as requested picture is processed accordingly.
The output picture that subsystem occurs at each described display control program interface can comprise the picture that EFIS is exported; Engine and unit warning system picture; Picture of map topography system output etc., or the picture of above system further can also be segmented, as EFIS being further subdivided into the picture of day earth, the picture of altimeter etc. the picture after these segmentations is gathered respectively.
The collection of these pictures can be gathered by the interface that uses operating system to provide, the windows(of Microsoft form for example) operating system provide for capturing desktop assigned address and specifying the interface function of big or small picture, the Xlib built-in function under linux system provides similar function equally.
Also can adopt image pick-up card directly from the output of picture, to gather.The picture of said system generally can output to VGA(video graphics array), DVI(digital visual interface) etc. interface, use special-purpose image pick-up card directly image to be gathered from interfaces such as these VGA, DVI.
Gathered picture is carried out to corresponding processing and can comprise the adjusting to the size of gathered picture, i.e. image scaling; Part or integral color are regulated; Image is carried out to cutting; Image is carried out to position to be adjusted as revolving light; Or add some symbols, lines, frame etc. to picture; Can also carry out contrast adjustment to picture and carry out the operation that the images such as figure image intensifying, pseudo color interpolation are processed.
As shown in Figure 1, there is subsystem and be used for generating required display interface in each interface of display control program, but the interface that these subsystems generate may be to need to revise and regulate.The picture that image acquisition subsystem, to each interface, subsystem output occurs gathers, and the collection of these pictures can be gathered by the interface that uses operating system to provide, and also can adopt image pick-up card directly from the output of picture, to gather.Each image acquisition subsystem can gather according to its operational capability the picture of one or more subsystem outputs, carrys out the number of concrete decision image capturing system according to the disposal ability of resolution, frame per second and the acquisition system of subsystem output picture.Figure 1 shows that each interface generates the situation of the corresponding image acquisition subsystem of subsystem.When gathering image, image is carried out to needed adjusting, these adjustings can comprise: the adjusting of the size of picture, i.e. image scaling; Part or integral color are regulated; Image is carried out to cutting; Image is carried out to position to be adjusted as revolving light; Or add some symbols, lines, frame etc. to picture; Can also carry out contrast adjustment to picture and carry out the operation that the images such as figure image intensifying, pseudo color interpolation are processed.
Step 2 sends each picture of processing in step 1 after overcompression by network.
If each picture after processing in step 1 directly sends by network, because picture is numerous, may cause blocking up of network, therefore need to before transmission, to picture, compress, for example, can adopt JPEG(joint photographic experts group) compressed format (being applicable to compress terrain graph) or GIF(graphics interchange format) compressed format (being suitable for compressometer surface and interface etc.).After image compression, adopt suitable procotol, as ICP/IP protocol sends to the image synthesis computer in step 3 by the image after compression.
