In order further to explain the present invention, below enumerate two preferred embodiments.First preferred embodiment
Please refer to Fig. 3, Fig. 3 is provided by the schematic diagram of the video wall that provides according to a preferred embodiment of the present invention.Please be simultaneously with reference to Fig. 1, mother picture data 300 representatives be to form the required every data of mother picture 100, can comprise pixel data, horizontal synchronization data, vertical synchronization data and clock pulse signal etc.At first, mother picture data 300 are added in the middle of the digital display 351,353,355 and 357.Digital display 351,353,355 and 357 is after receiving mother picture data 300, can be from the mother picture data 300 central required sub-image data (not shown)s of extraction itself, and with the sub-image data obtained with full screen display, then, display 351,353,355 and 357 screen just can show sprite 131,133,135 and 137, these 4 shown pictures of display are pieced together meeting form a combined picture 130, hereinafter, will elaborate at the practice that digital display extracts sprite.
Make digital display 351,353,355 and 357 can be the ratio processor of establishing in the digital display from the key of the required sub-image data of extraction in the middle of the mother picture data 300 itself.Because digital display (comprises LCD LCD, plasma scope PDP etc.) Shi Ji resolution is fixed, therefore when the signal resolution degree of input is different from actual resolution, digital display can use the ratio processor (scale IC) of a numeral that input picture is scaled to the size identical with the actual resolved degree, just image is delivered to the output device of digital display afterwards, and the ratio processor is except the size that can adjust input picture, the picture data that also can extract certain specific region in input picture is as image output, therefore as long as original function of correct proportion of utilization processor just can replace video and audio frequency separator in the conventional practice.
Please refer to Fig. 4, the schematic diagram of the picture data conversion of display 351 inside in Fig. 4 presentation graphs 3.As shown in the figure, after mother picture data 300 added the ratio processor of establishing in the displays 351 410, ratio processor 410 can be done relevant computing at the every data in the mother picture data 300, required sub-image data 331 when extracting video picture.
Discuss with the present practice, comprise in the ratio processor 410 and carry out the required all kinds of algorithms of computing, with the proportional algorithm is example, the user can be by means of the setting of parameters in the proportional algorithm, specify and mother picture will be cut out how many ratios, how many ratios of displacement and be out of shape how many ratios, and then from mother picture, extract the part of wanting and be put into suitable position and shown, to form sprite.With regard to the present practice, proportional algorithm need be set each relevant parameter when carrying out, and just can extract the pairing sub-image data of each sprite.For instance, comprise the required parameter A of computing, B parameter and parameters C in the proportional algorithm, if the user is set at a1 with parameter A, B parameter is set at b1, parameters C is set at c1, and then proportional algorithm can extract sub-image data 331 through after the computing in mother picture data 300, then, digital display 351 only needs to be shown according to sub-image data 331, can demonstrate sprite 131.
According to above-mentioned example, when digital display 351 will demonstrate sprite 131, only need the parameter A of proportional algorithm in the ratio processor 410 is set at a1, B parameter is set at b1, being set at c1 with parameters C gets final product, so can be with a1, b1 and c1 are defined as and form the required boundary parameter of sub-image data 331, in like manner, if the parameter A of ratio processor in the digital display 353 is set at a2, B parameter is set at b2, and when parameters C is set at c2, can in mother picture data 300, extract suitable sub-image data to show sprite 133, then definable a2, b2 and c2 are for forming the required boundary parameter of sprite 133.Similarly, the user also can be defined as a3, b3 and c3 and form the required boundary parameter of sprite 135, and a4, b4 and c4 be defined as form the required boundary parameter of sprite 137.Because each boundary parameter and each available sprite have man-to-man corresponding relation, for example, sprite A is corresponding with boundary parameter A, and sprite B is corresponding with boundary parameter B.After providing a border parameter to proportional algorithm, proportional algorithm will be made the sub-image data that computing will be extracted with the preset proportion processor to this boundary function.For example, after providing boundary parameter A to proportional algorithm, proportional algorithm promptly can the preset proportion processor removes to extract the sub-image data of sprite A, in like manner, after providing boundary parameter B to proportional algorithm, proportional algorithm promptly can the preset proportion processor removes to extract the sub-image data of sprite B.
Show (on screen display on the so-called screen, OSD) be to assist boundary parameter in user's preset proportion processor by the alternative option of screen display, making the user can easily set this digital display is that regional picture that will show in the mother picture.Basically, can decide which OSD option, and the user can choose suitable OSD option according to the needs of itself according to the number and the arrangement of display.
Please refer to Fig. 5, Fig. 5 represents to use the OSD option of the video wall that 4 digital display group become.As shown in the figure, 501 expressions of OSD option show whole mother picture, and when the user selected OSD option 501, digital display promptly can receive and the pairing boundary parameter of mother picture, and then mother picture is presented on the screen.In like manner, the regional picture in the mother picture upper left corner is chosen in 502 expressions of OSD option, when the user selects OSD option 502, digital display promptly can receive the boundary parameter with the regional picture correspondence in the mother picture upper left corner, for example be parameter a2, b2 and c2, and then zoom into the sprite that is extracted full frame.And the regional picture in the mother picture upper right corner is chosen in 503 expressions of OSD option, when the user selects OSD option 503, digital display promptly can receive the boundary parameter with the regional picture correspondence in the mother picture upper right corner, and then zooms into the sprite that is extracted full frame.The regional picture in the mother picture lower left corner is chosen in OSD option 504 expression, and when the user selected OSD option 504, digital display promptly can receive the boundary parameter with the regional picture correspondence in the mother picture lower left corner, and then zooms into the sprite that is extracted full frame.The regional picture in the mother picture lower right corner is chosen in OSD option 505 expression, and when the user selected OSD option 505, digital display promptly can receive the boundary parameter with the regional picture correspondence in the mother picture lower right corner, and then zooms into the sprite that is extracted full frame.
