Description
Technical field
The present invention relates to a kind of display device and picture adjusting method thereof and a kind of video information wall, particularly relate to picture adjusting method that is applied to the video information wall numeric display unit and video information wall (APPARATUS ADAPTIVE FOR A DISPLAY WALL with this display device, IMAGE ADJUSTMENT METHOD, AND A DISPLAY WALL THEREWITH).
Background technology
In recent years, video information wall has been widely used in the occasion of large-scale demonstration, video information wall is to merge with several display device to arrange, wherein indivedual display device are chosen parts of images that should the position according to the position of its arrangement, be amplified to the full frame size of this display device, all display device merge the common complete picture that shows an input picture in back.
See also shown in Figure 1ly, it is the synoptic diagram of 1 video information wall forming of 3 * 3 display device.As shown in Figure 1,100 is a display source signal, and 111,112,113,121,122,123,131,132 and 133 is that nine display device are lined up a video information wall with 3 * 3 frameworks.The image display signal of display source signal 100 is connected to each display device respectively in regular turn by signal wire 140,141,142,143,144,145,146,147 and 148, is connected in series the images display signal to all display device via signal connecting line in regular turn.The display device of these serial connections is chosen corresponding a part of picture material according to its arrangement position and is amplified demonstration, merges the back and forms an original image that amplifies.
Because numeral (Digital) display technique has clear sharp keen compared to traditional simulation (Analog) display technique, transmit characteristics such as undistorted, therefore digital display element spare (for example LCD, PDP, DMD) replaces traditional analog display elements gradually in recent years, and is applied to the display device of a new generation.Can control the size and the position of output image by the deflection circuit of adjustment level and vertical direction based on the display device of CRT.And the numeric display unit of a new generation, its inner one video signal convergent-divergent wafer (Scaler) of configuration usually is as the usefulness of image zoom and turnover rate conversion.The adjustment of the big or small display position of image can be reached with picture demonstration reference position and size by the magnification of control video signal convergent-divergent wafer.
Existing known display technique of amplifying about numeral, provide one group of default amplification mode and (as be amplified to the full frame of display device, keep Aspect Ratio and amplify, keep former resolution sizes) supply the user to select the magnification of amplification mode setting display device wherein.The default amplification mode of this kind and being not suitable for is applied to the image adjustment of indivedual display device of video information wall.Because in the application of video information wall, wherein indivedual display device must be finely tuned its magnification and position sometimes and could risk a continuous and complete image when merging according to its position difference.
In order to make the image between display device and the display device can be continuous, in the past when adjusting the picture position, general all is the position of adjusting input picture, and this way has a shortcoming, and the degree of accuracy that is exactly the output image adjustment will be relevant with the multiplying power that image amplifies.
For example, a level is exaggerated 2 times image, and 1 point (pixel) of mobile input picture signal then will be exaggerated into 2 points (pixel) at the horizontal signal of output image.Therefore, this adjustment mode can not make that the image that is shown is continuous between the display device of adjacent position, and its topmost image is discontinuous to be because contain the problem that the image signal of radix point multiple amplifies.Video information wall with 3 * 3 frameworks is an example, if the picture that will amplify XGA (Extended Graphics Array) (just 1024 * 768) resolution is when having the video information wall of .3 * 3 display device, then if each level input signal of average computation should be cut into 1024/3=341.3, but the least unit of input signal is 1pixel, therefore if go to amplify the information that then can lack some display image again with 341, then there is partial image will repeat again if do amplification, will makes that the image between each adjacent display device of video information wall can't be continuous with 342.
Existing knownly amplify the application that shows about numeral and mostly be several groups of default amplification modes, for example be amplified to display device full frame (Fill All), keep Aspect Ratio and amplify (Fill AspectRatio) and keep former resolution sizes (Native-Resolution) or the like.Understand for convenience, below illustrate, see also Fig. 3 A to shown in the 3D.Picture 310 among Fig. 3 A is that a resolution is 720 * 400 acquisition picture, and the resolution of the display device of desire output is 1024 * 768, if amplification mode is the full frame (Fill All) that is amplified to display device, then shown in the display frame 320 of Fig. 3 B, it amplifies the back picture and fills up whole display device its output picture.But, because therefore the ratio difference that the picture length and width are amplified can cause the distortion of image Aspect Ratio.If amplification mode amplifies (Fill Aspect Ratio) for keeping Aspect Ratio, then shown in the display frame 330 of Fig. 3 C, the Aspect Ratio of original picture is constant for its output picture, but the up and down edge of display frame stays each white space of 1024 * 100 approximately.And if amplification mode is for keeping former resolution sizes (Native-Resolution), its output picture shown in the display frame 340 of Fig. 3 D, screen resolution constant (720 * 400), however stay white space around the viewing area.The user can select an above-described amplification mode according to behaviour in service or use habit, yet the default amplification mode of this kind but can't apply to the framework of video information wall.When a plurality of display device merged picture of demonstration, magnification must be finely tuned with the degree of accuracy of a point of level or a vertical line sometimes, just can intactly risk the full frame viewing area.
This shows that above-mentioned prior art obviously still has inconvenience and defective, and demands urgently further being improved.In order to solve problems of the prior art, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but does not see always that for a long time suitable design finished by development, and this obviously is the problem that the anxious desire of relevant dealer solves.
Because above-described shortcoming, the present invention proposes a kind of amplification method of adjustment that is applied to display device, and particularly about being applied to the amplification method of adjustment of video information wall, it is characterized in that the magnification adjustment for picture, its degree of accuracy is to finely tune with the degree of accuracy of a point of level or a vertical line.
