Embodiment
Closing aforementioned and other technology contents, characteristics and effect of the present invention, in the following detailed description that cooperates with reference to a graphic preferred embodiment, can clearly understand.
Consult Fig. 1, the present invention is that (Remote I/O, RIO) technology is reached in the utilization far-end I/O based on UPnP that Intel Company developed in this preferred embodiment that the low resolution display device presents the method for high image quality web data and application thereof.That is, can utilize the framework of conversion multiplying arrangement 2 of the RIO servomechanism 8 of a server-side and a client and technology of the present invention to reach the high image quality web data is presented in purpose on the low resolution display device 1.
As know this skill person and all know, the picture of desiring high resolving power (as 800 * 600) the digital network page data that presents among the present invention on this low resolution display device 1 is to be made of a plurality of pixels.As for, 1 of this display device comprises that one has the display panel 11 of a plurality of unit 111.
This conversion multiplying arrangement 2 for example can be a set top box (Set Top Box, STB), or a PDA main body.If this conversion multiplying arrangement 2 is a set top box, then this display device 1 is traditional low resolution cathode ray tube television receiver, and this input block 23 is the telepilot of set top box.Perhaps, if this conversion multiplying arrangement 2 is the PDA main body, then this display device 1 PDA screen that is low resolution, and this PDA comprises that more one covers the Trackpad of this display panel 11, and this input block 23 is one to send the writing pencil that this chooses instruction in order to touch this Trackpad.
Except that this input block 23, this conversion multiplying arrangement 2 more comprises a housing 20 and is located at a compressing and converting unit 21, a graphics processing unit 22 and an input port 24 in this housing 20.This compressing and converting unit 21 supplies to convert a web data to an image file, and compresses this image file, and the pixel that causes this compressed image file is the number of unit corresponding to this display panel.This graphics processing unit 22 for the image file after will compressing according to the screen unit position of this pixel correspondence respectively, be divided into a plurality of frames, and accept to choose instruction from one of this input block 23, define one and be selected frame, make a described new viewing area that is selected the included pixel amplification of frame corresponding to this display panel with a predetermined multiplying power, and the pixel location data of compensation shortcoming data, for exporting this new viewing area to.This input port 24 is in order to receiving the webpage web data, and is electrically connected to this compressing and converting unit 21.
Consult Fig. 1 to Fig. 3, the present invention comprises following steps in the method that the low resolution display device presents the high image quality web data.At first, shown in step 91, obtain the image file of a network data earlier, wherein this web data is to be downloaded from world-wide web by RIO servomechanism 8, be built in web browser control interface (the web browser controlinterface of the browser in the RIO servomechanism 8 in then utilizing, the Iweb Browser/Iwdb Browser2 interface that is provided by Microsoft company for example, it is to comprise Microsoft Visual C high level language for the main interface that is given in Microsoft Web browser Active X control and it) web page files is converted to as Portable network graphic (Portable Network Graphics, PNG) the equal resolution image file of form, and see through this input port 24 this image file is sent to this compressing and converting unit 21.For example, if the resolution of the original web page of downloading from world-wide web is 800 * 600, then the resolution via the converted PNG image file of the browser in this RIO servomechanism 8 still is 800 * 600.
Then, shown in step 92, utilize this compressing and converting unit 21 these image files of compression, make the pixel of this compressed image file corresponding to the number of the unit 111 of display panel 11.For example, if the cell resolution of the display panel 11 of display device 1 is 320 * 240, then this compressing and converting unit 21 can further compress 800 * 600 PNG image file, makes its resolution be reduced to the resolution 320 * 240 identical with display panel 11.
Then, shown in step 93, utilize this graphics processing unit 22 with after compression low-resolution image file in the above-mentioned steps 92 according to the screen unit position of this pixel correspondence respectively, be divided into a plurality of frames.For example, can be as shown in Figure 3, the picture of display device 1 is distinguished into nine frames such as first frame 121 to the 9th frames, 129 grades.
Then, shown in step 94, the user utilizes input block 23 to assign and chooses instruction, and after this graphics processing unit 22 receives this and choose instruction, is selected frame just can define one.For example, these first frame, 121 to the 9th frames 129 can correspond to No. 1 to No. 9 numerical key of telepilot respectively.So when the user pushed a certain numerical key on the telepilot, the pairing frame of this numerical key that is pressed can be defined as and be selected frame.For example, when the user pushed No. 5 numerical keys on the telepilot, pairing the 5th frame 125 of these No. 5 numerical keys can become the state of being selected.
Then, shown in step 95, this graphics processing unit 22 can make an above-mentioned new viewing area that is selected the included pixel amplification of frame corresponding to this display device 1 with a predetermined multiplying power.For example, with Fig. 3, if should predetermined multiplying power be 3 times, the then former web data that is shown in all pixels in the 5th frame 125 can amplify corresponding to full screen zone (320 * 240) through after the rerunning of graphics processing unit 22.
Yet, in above-mentioned steps 95, when being selected the included pixel of frame and amplifying corresponding to new viewing area, the cell resolution that new viewing area is contained must be greater than being selected the included pixel resolution of frame originally, therefore the technology that must handle with known image is that the unit that has more in the new viewing area defines suitable image information respectively, promptly according to the data of this neighbor respectively, computing replenishes the pixel location data of shortcoming data, and output is presented in this new viewing area, and wherein the technology handled of this known image for example can be bilinear interpolation method (Bilinear Interpolation).
Conclude above-mentioned, the present invention presents the method for high image quality web data and amplifies conversion equipment and domestic system can be in order to being presented in web data on the low resolution display device 1 with high image quality in the low resolution display device, and is not required to be the webpage of low resolution display device 1 other customized low-definition version.
The above person of thought, it only is preferred embodiment of the present invention, when not limiting scope of the invention process with this, promptly the simple equivalent of being done according to claim of the present invention and description of the invention content generally changes and modifies, and all should still belong in the scope that patent of the present invention contains.
