Embodiment

In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.

The embodiment of the present invention contains territory by the minimum of obtaining delta data district in the graph area of source, calculate this minimum containing correspondence position and the size of territory in the targeted graphical district, wherein, the coordinate of the correspondence position in the described targeted graphical district calculated, wide and high are all accurate integers; And be processed in the targeted graphical district view data in corresponding domain and complete renewal containing the pixel data in territory minimum in the graph area of source.

Fig. 1 shows the flow process of the method that the embodiment of the present invention provides, and details are as follows.

In step S101, determine in the graph area of source more neofield of pixel;

Wherein, graphics system can be known the current data variation that whether has at any time automatically, and can define accurately in the graph area of source according to the situation of judgement pixel more neofield x, y, w, h}, x, y represents coordinate, w, h represents respectively width and height.The data variation of general source graph area is all that new graphic scene that the service application in graphics system triggers is drawn and caused, for example by the new scene of message trigger etc.Certainly, in graphics system, do not stop the figure demonstration changed, great majority are all that local data is changing.

In step S102, obtain the minimum in delta data district in the graph area of source containing territory.

As embodiments of the invention, the inventive method is defined as minimum containing territory: under targeted graphical district size and ratio condition restriction, complete in the graph area of source when pixel is upgraded area update and need minimum rectangular area to be processed.

Wherein, this minimum meets two characteristics containing territory: the one, the minimum starting point coordinate containing territory X, in the corresponding starting point coordinate that Y} calculates according to the condition in targeted graphical district respectively { X ', Y ' }, X ' and Y ' they are all accurate integers, in calculating, do not contain decimal place; The 2nd, the minimum wide W containing territory and the wide W ' of correspondence and the high H ' that high H calculates according to size and the ratio in targeted graphical district respectively are all accurate integers.Because minimum meets these characteristics containing territory on mathematics, when so each local data upgrades, border of each pixel in corresponding figure just in the targeted graphical district, the zone of calculating according to neighborhood, not there will be the pixel operation that contains decimal in renewal process.

In specific implementation process, the integral width of supposing the source graph area is ww, highly for hh; The integral width in note targeted graphical district is WW, be highly HH, pixel region of variation in calculating source graph area x, y, w, the minimum of h} contain territory X, Y, W, the step of H} is:

(1). calculate respectively the width (ww and WW) in source graph area and targeted graphical district and highest common factor Mw and the Mh of height (hh and HH); The highest common factor that the embodiment of the present invention adopts method of successive division to calculate two numerals can adopt.

Method of successive division asks the step of highest common factor of two numbers as follows: first by a little number except a large number, obtain first remainder; Remove a little number with first remainder again, obtain second remainder; Remove first remainder with second remainder again, obtain the 3rd remainder; So successively by a rear number, remove previous remainder, until remainder is 0.So, last divisor is exactly required highest common factor.Certainly, if last divisor is 1, two so original numbers are mutual prime rwmbers.

(2). respectively zoning x, y, w, minimum corresponding to h} containing territory X, Y, W, the item numerical value in H}, specific formula for calculation is:

Note Zw=ww/Mw; Zh=hh/Mh; INT is for rounding operation

X＝INT(x/Zw)*Zw；

Y＝INT(y/Zh)*Zh；

If Zw ≠ 1, W=INT ((w+ (x-X)+(Zw-1))/Zw) * Zw; Otherwise W=w;

If Zh ≠ 1, H=INT ((h+ (y-Y)+(Zh-1))/Zh) * Zh; Otherwise H=h;

In step S103, calculate in the figure of source minimum containing correspondence position and the size of territory in the targeted graphical district.

According to size and the ratio in targeted graphical district, calculate in the graph area of source minimum containing territory X, Y, W, H} is in Zhong corresponding region, targeted graphical district { X ', Y ', W ', H ' }.Specific formula for calculation is: X '=X*WW/ww; Y '=Y*HH/hh; W '=W*WW/ww; H '=H*HH/hh; The numerical value of the position that calculates the Geng new district by this step (X ', Y ') and wide height (W ', H ') is all accurate integers, meets like this physical characteristics requirement of pixel operation.

In step S104, pixel data in territory in the graph area of source is processed into to view data renewal in territory in the targeted graphical district.

Wherein, the source graph area W, be pixel data in the H} territory for X, Y, i.e. and a video data block, targeted graphical district { X ', Y ', W ', H ' } is also pixel data in territory, i.e. a video data block.Due to image block X, Y, W, H} and image block { X ', Y ', W ', H ' } vary in size, so need to image block X, Y, W, the pixel data in H} is processed into the view data that meets image block { X ', Y ', W ', H ' } size.

Then, in { X ', Y ', W ', H ' } territory, complete once and upgrade the result data of processing is actual is updated in the targeted graphical district.

Certainly, in specific implementation process, also can be directly by finally having carried out result data that convergent-divergent processes and be positioned over { X ', Y ', W ', H ' } in targeted graphical district, so just can reduce data Replica one time.

Refer to Fig. 2, the figure shows between graph area the scope that the minimum that upgrade when local data upgrades contains territory.

Wherein, in Fig. 2, a figure has illustrated the target area district that calculate from mathematical meaning in the data variation territory in the figure of source, physical characteristics due to pixel data, in fact zone with decimal can not realize, and the result after fractions omitted and objective result have very large accumulative total difference, think that directly more the new data actual uplink is obstructed;

In Fig. 2, b figure and c figure have illustrated in the figure of source minimum that two different data variation territories calculate containing territory, and it is just the solution of a figure that b schemes.Wherein, in b figure, the black dotted lines district is more new district of the pixel calculated on mathematics, and the solid black lines frame adjacent with this black dotted lines district is more new district, i.e. minimum neighborhood of actual pixel; B figure black dotted lines district is more new district of the pixel calculated on mathematics, with this black dotted lines district next-door neighbour's little solid black lines district be more new district, i.e. minimum neighborhood of actual pixel.

As can be seen from Figure 2 the minimum in a zone all has relation containing position and the wide height at Yu Qi place, territory, and what calculate contains the condition in territory containing position, territory and wide height in horizontal and vertical all satisfied minimums, so just guaranteed just in time to be dropped on the border of each pixel by the target area in the targeted graphical district of calculating containing territory.

Due to the embodiment of the present invention by the graph area of source more the minimum of neofield upgrade processing, new image data more containing territory, this is than the data bulk treatment by whole graph area and upgrade whole updating method once, has greatly reduced the pixel data amount to be processed that needs.Particularly in the graph area of source, only have a few pixels upgrade or among a small circle in data while changing, minimum contain territory can be more much smaller than whole source graph area.

And, because having greatly reduced, the embodiment of the present invention needs pixel data amount to be processed, while upgrading, naturally also just greatly reduced the calculated amount of image processing process at every turn, greatly reduced system consumption, and greatly improved the efficiency of graph area Data Update.

The idiographic flow of graphic processing method provided by the invention below is described with concrete example.

The GUI figure arranged in the Set Top Box graphics system on probation the realization is drawn by the pal mode standard, draws district 720 * 576.During by the PAL display mode, viewing area is 720 * 576; During by the NTSC display mode, viewing area is 720 * 480; During by the high definition display mode, viewing area is 1344 * 756.

The figure that in Set Top Box, the pal mode standard is drawn shows under the high definition display mode.

At first determine in the graph area of source more neofield { x, y, w, h} of pixel;

In current drafting district x=101, and y=101, w=100, the h=100} area data needs to upgrade.According to the computing method in literary composition, various data initial values should be respectively: ww=720, hh=576; WW=1344, HH=756.

Secondly, in the graph area of source, find x, y, w, the minimum of h} pixel domain containing territory X, Y, W, H}, the steps include:

(1). calculate respectively the width (ww and WW) in source graph area and targeted graphical district and highest common factor Mw and the Mh of height (hh and HH).Calculate the maximum approximate number algorithm of two numbers according to above-described method of successive division, calculate several: the Mw=48 of ww and WW, the Mh=36 of hh and HH;

(2). respectively zoning x, y, w, minimum corresponding to h} containing territory X, Y, W, the item numerical value in H}, concrete calculating:

Zw＝ww/Mw＝720/48＝15；

Zh＝hh/Mh＝576/36＝16；

X＝INT(x/Zw)*Zw＝INT(101/15)*15＝90；

Y＝INT(y/Zh)*Zh?INT(101/16)*16＝96；

Because Zw ≠ 1,

So W=INT ((w+ (x-X)+(Zw-1))/Zw) * Zw=INT ((100+ (101-90)+(15-1))/15) * 15=120;

Because Zh ≠ 1,

So H=INT ((h+ (y-Y)+(Zh-1))/Zh) * Zh=INT ((100+ (101-96)+(16-1))/16) * 16=112;

After completing above step, final calculating acquisition x=101, and y=101, w=100, the minimum of h=100} pixel domain is { X=90, Y=96, W=120, H=112} containing territory.

Then, calculate in the graph area of source minimum containing territory { X, Y, W, the corresponding domain of H} in the targeted graphical district { X ', Y ', W ', H ' };

Described according to above, concrete calculating:

X’＝X*WW/ww＝90*1344/720＝168；

Y’＝Y*HH/hh＝96*756/576＝126；

W’＝W*WW/ww＝120*1344/720＝224；

H’＝H*HH/hh＝112*756/576＝147；

Obviously, the more neofield finally obtained X '=168, Y '=126, W '=224, the numerical value of the position of H '=147} (X ', Y ') and wide height (W ', H ') is all accurate integers, there is no error in all computation process, everything all provides the technical guarantee of mathematics aspect for the accurate renewal of final pixel data.

By in the graph area of source X, Y, W, in the H} territory, pixel data is processed in the targeted graphical district view data in { X ', Y ', W ', H ' } territory, wherein, this processing procedure can be for zooming in or out.

Because be processes to take the graph data that pixel is unit in graph area.X, and Y, W, the data essence in H} territory and { X ', Y ', W ', H ' } territory is complete one by one image block, also can be regarded as the figure data bitmap of a frame frame.Take these data as the view data body of fundamental construction one-tenth based in internal memory, then according to current { X, Y, W, the H} territory and X ', Y ', W ', H ' } the territory magnitude relationship, the method that adopts image to process is carried out image block integral body and is zoomed in or out, be about to image block { X=90, Y=96, W=120, the H=112} pixel data be processed into the target image piece X '=168, Y '=126, W '=224, H '=147}.

Finally, in { X ', Y ', W ', H ' } territory, complete once and upgrade the result data of processing is actual is updated in the targeted graphical district.

Due to image block be just in time according to target graph area X '=168, Y '=126, W '=224, the image size at H '=147} place and form are processed, so directly the result images piece is covered X '=168, Y '=126, W '=224, H '=147} gets final product.
