In order to make the object, technical solutions and advantages of the present invention clearer, below in conjunction with the accompanying drawings with specific embodiment pair
The present invention is described in detail.
The present invention provides a kind of picture transmission method, is that the present invention realizes the processing method of terminal in picture transmission method,
Fig. 1 is the schematic flow sheet that the present invention realizes the preferred embodiment one of picture transmission method, as it is shown in figure 1, the preferred embodiment
Comprise the following steps:
Step S101, according to the picture size preset, it is thus achieved that at least two picture required parameter；By described at least two figure
Sheet required parameter is sent to server, so that described server obtains according to described picture required parameter by least two link
Obtain at least two image data.
Concrete, after user enters the interface of display picture of terminal, the picture shown by terminal will be browsed to, such as fruit dot
Hit this picture shown in interface, then it represents that user asks to obtain the picture of fine definition, and terminal will be received for currently
The picture display request of the image data of display；Wherein, the image data of display can be the picture in news, the street in map
Picture etc. in scape picture or Search Results.
When terminal is received for the picture display request of certain image data, according to the picture size preset, generate at least
Two picture required parameter R, described picture required parameter R=(2l,k)；Wherein, described picture size refers to currently displaying
The size of the image data of fine definition that image data is corresponding, described picture size is 2M×2NSquare, 1≤k≤
Min (M, N), wherein, picture size is equal to length width of picture and the width height of picture, wherein, length width etc.
In 2M, width height is equal to 2N, this M is equal to the numerical value of described power during the power table diagram leaf length with 2, and N is equal to the power table with 2
The numerical value of described power during diagram sheet width.Such as, M is equal to 10, and N is equal to 11, then min (M, N)=10, k can take in 1 to 10
Any one integer, such as k are equal to 5.
In this preferred embodiment, the value of k needs to pre-set, and for same image data, each picture request ginseng
In number R, the value of k is identical；Picture required parameter R=(2l, k) in, 0≤l≤k-1, and l is integer, therefore, generation is at least
Two picture required parameters include: R=(1, k), R=(2, k), R=(4, k) ..., R=(2k-2, k), R=(2k-1,k)；Terminal
The number of the picture required parameter generated is equal to k, and for same image data, l in k the picture required parameter that terminal generates
Value different, in each picture required parameter, the value of l is unique；Picture required parameter is for indicating in complete image data
The data of different piece, and the data of every part do not have overlap, to realize asking complete picture by multiple links simultaneously
The different piece of data rather than obtain the different portions in complete image data by the repeatedly request of same link
Point.
Terminal, after generating at least two picture required parameter R, needs the http setting up between at least two and server
Link, and linked by this at least two http, at least two picture required parameter R of generation is sent to server, is sending out
While sending picture required parameter R, in addition it is also necessary to send the mark of the image data asked.Wherein, each http link is only used
In sending a picture required parameter, the quantity of the http hence set up link is equal in k, the i.e. present invention, and the picture of generation please
The quantity asking the http link of the quantity of parameter R, foundation is equal to k.Wherein, receiving and sending picture by least two http chain please
The method seeking parameter is: terminal to server sends at least two request, and each request includes the URL address of server, picture
Required parameter and the mark of image data, the picture required parameter i.e. received and sent with the l+1 http chain is R=(2l,k)。
In the present invention, the picture required parameter R sent to server is decimal data, and this decimal data can convert
For binary data, i.e. represent asked image data, such as, 11 by binary data ... the binary data table of 11
Show complete image data, 00 ... 1 ... the l position of the binary data of 00 is 1, other are all 0 years old, then asked
The pixel of image data is the 1/2 of complete image datak-l, it may be assumed that for picture required parameter R=(2l, k), by 2lIt is converted into
After binary data, according to low level in binary data to high-order order, the value of l-1 position is 1, and the value of remaining is 0, its
In, in binary data, low level is to Far Left by the rightmost of data sequence to high-order order；In picture required parameter R
K represent 2lThe data amount check in the binary data obtained is converted by decimal data, if 2lConverted by decimal data and obtain
The number of the binary data obtained less than k, then utilizes 0 to fill a high position for binary data.
Such as, the k preset is equal to 5, and the http that terminal is set up between 5 with server links, and generates 5 picture request ginsengs
Number, wherein, the picture required parameter received and sent by the l+1 http chain is as shown in table 1:
Table 1
| 1st http link (l=0) | R=(20, 5)=(00001,5) |
| 2nd http link (l=1) | R=(21, 5)=(00010,5) |
| 3rd http link (l=2) | R=(22, 5)=(00100,5) |
| 4th http link (l=3) | R=(23, 5)=(01000,5) |
| 5th http link (l=4) | R=(24, 5)=(10000,5) |
Step S102, receives, by the link of described at least two, the described at least two picture number that described server sends
According to.
Step S103, merges described at least two image data, it is thus achieved that new image data.
Concrete, terminal receives at least two image data by least two link set up from server, and terminal will
The image data preferentially received is shown to user, and after receiving new image data, by this image data with have shown that
Image data merges, it is thus achieved that the higher image data of definition, and after receiving all of image data, terminal is by complete for display
Image data.
Owing to terminal first receives the image data of the pixel composition indicated by the picture required parameter that l value is minimum, work as end
When end receives the image data of the composition of the pixel indicated by picture required parameter of l=0 from the 1st link, create one 2M
×2NMatrix Mt, the image data that this is obtained by terminal is filled into the relevant position of this matrix, and filling process services exactly
Device extracts the inverse process of pixel, i.e. according to this picture required parameter R, it is thus achieved that binary data, then according to low level is to high-order
Order binary data is traveled through, when the l bit data traversed is 0, continue traversal, the l bit data traversed
When being 1, need filler pixels in matrix Mt, during filler pixels, first with the 0th position in matrix Mt as starting point, with 2k-lFor
Every determining the abscissa of the position needing filler pixels, then with the 0th position in matrix Mt as starting point, with 2k-lDetermine for interval
Need the vertical coordinate of the position of filler pixels, so that it is determined that the position that pixel is in matrix Mt, by that analogy, it is thus achieved that all pixels
Position in matrix Mt；When terminal receives what the pixel indicated by the picture required parameter of l=1 formed from the 2nd link
During image data, utilize above-mentioned identical filling process, this image data is filled into the relevant position of matrix, it is achieved will be from two
The merging treatment of the image data that individual chain receives；The definition of the new image data that merging treatment obtains is more than appointing of receiving
The definition that one image data is corresponding, the new image data that terminal demonstration obtains after merging.
Terminal often receives an image data and is just merged with the image data having shown that by this image data, it is thus achieved that clear
Spending higher image data, and show the image data of this acquisition, therefore the definition of the image data of terminal demonstration gradually increases
Add, until definition reaches maximum,
Such as, it is 000 when terminal obtains definition ... 00100 ... 0 (front j position is 0, and middle i-th bit is 1, last k-j-i
Position be 0) image data I2Time, by image data I2It is 000 with the definition received before ... 01000 ... 0 (front j position is 0, the
I-1 position is 1, and rear k-j-i+1 position is 0) image data I1Merging, generating definition is 000 ... 01100 ... 0 (front j position is 0,
The i-th-1 and i-th bit are 1, and rear k-j-i position is 0) image data I3；Merging method is: enter according to the two of picture required parameter
Data 000 processed ... 01000 ... 0, it is thus achieved that image data I1In all pixels position in matrix Mt, then by image data I1
In all pixel fillings in matrix Mt；Again according to the binary data 000 of picture required parameter ... 00100 ... 0, it is thus achieved that picture
Data I2In all pixels position in matrix Mt, by image data I2In all pixel fillings in matrix Mt, finally go
Fall the part not being filled in matrix Mt, utilize the pixel of the part having been filled with to generate image data I3。
The present invention also provides for a kind of picture transmission method, is that the present invention realizes the process side of server in picture transmission method
Method, Fig. 2 is the schematic flow sheet that the present invention realizes the preferred embodiment two of picture transmission method, as in figure 2 it is shown, this is preferable to carry out
Example comprises the following steps:
Step S201, receives at least two picture required parameter that terminal is received and sent by least two chain, each described
Picture required parameter is that described terminal obtains according to the picture size preset.
Step S202, obtains at least two image data according to described at least two picture required parameter.
Concrete, at least two picture required parameter received from terminal, server is according to each picture request ginseng
Number obtains the image data that this picture required parameter is corresponding, it is thus achieved that the method for image data is:
Firstly, since terminal is in order to reduce the flow that picture required parameter is consumed, the picture required parameter R of transmission is ten
Binary data, therefore, server is converted into binary data firstly the need of by picture required parameter R；Such as, picture required parameter
R=(4,5), server obtains R=(00100,5) after R=(4,5) is converted to binary data.
Then, server obtains the complete picture number of correspondence in data base according to the mark of the image data received
According to, described complete image data refers to the image data of the definition maximum that in data base, this mark of preservation is corresponding；Institute
State image data and refer to the pixel of picture.
Then, the binary data obtained according to picture required parameter R, according to low level to high-order order, is entered by server
Row traversal, if the l bit data traversed is 0, then continues traversal；If the l bit data traversed is 1, then need from
Obtain extraction pixel in complete image data, before extracting pixel, need first to determine the abscissa set of pixel, it may be assumed that
Abscissa set X={x}, wherein, x=2k-l× T, T=0,1,2 ..., J, 2M-1＜ 2k-l× J ＜ 2M-1；Represent:
Numerical value x in abscissa set X is to start to take from 0, and each value is spaced apart 2k-l, and span is less than or equal to complete
The width of image data.
Determine the vertical coordinate set of pixel again, it may be assumed that
Vertical coordinate set Y={y}, wherein, y=2k-l× T, T=0,1,2 ..., J, 2N-1＜ 2k-l× J ＜ 2N-1；Represent:
Numerical value y in vertical coordinate set Y is to start to take from 0, and each value is spaced apart 2k-l, and span is less than or equal to complete
The height of image data.
According to the abscissa set X={x} that determines and vertical coordinate set Y={y}, it is thus achieved that and the coordinate of pixel (x, y), its
In, x ∈ X and y ∈ Y, represent that the coordinate of described pixel is all combined result of x and y；The coordinate of the pixel of described acquisition is entered
Row filter, removing x can be by 2k-l+1Divide exactly and y can be by 2k-l+1The coordinate divided exactly.
Finally, server is after traveling through binary data, and the coordinate of the pixel that foundation determines is at complete picture
Data retain the pixel of these coordinate positions, the pixel of other positions is taken out, obtain photo current according to the pixel retained
Image data corresponding to required parameter R.
The two or more image data obtained according to two or more picture required parameter R is sent to terminal by server；This
In, can all configure pixel processing order at server and terminal in advance, so, server can be according to default processes pixel
The order pixel to extracting is queued up, and the pixel obtained after queuing up is sent to terminal, and so, terminal can be according to identical pixel
Processing sequence by pixel filling to specify position；Such as, pixel processing order can be to queue up according to the sequencing of traversal, right
Different pixels under same traversal order, can rank according to the order that abscissa is ascending, for abscissa
Identical pixel, can rank according to the order that vertical coordinate is ascending.
It should be noted that the binary system obtained for indicating picture required parameter to convert due to l in picture required parameter R
In data, numerical value is the data bit of 1, will be after picture required parameter is converted into binary data, according to low level to high-order suitable
Sequence, in this binary data, the value of l-1 position is 1, and therefore the value of l is the biggest, represents 2k-lValue the least, then the pixel extracted is more
Many, thus the pixel of the server image data that is sent to terminal is the most, therefore causes terminal to receive the speed of image data
The slowest, so generally, terminal preferentially receives what server sent, is obtained according to the picture required parameter R that l is minimum
Image data, therefore the order of the image data that terminal receives according to l in picture required parameter R corresponding to image data by little to
Big order, thus ensure that terminal can be according to the image data received, the image data that display resolution is the highest.
Step S203, by described at least two image data, is sent to described terminal by the link of described at least two.
Concrete, after server at least two picture required parameter, for the most each picture required parameter, all can obtain
This image data indicated by picture required parameter, the image data that then will obtain, by sending the chain of picture required parameter
Connecing, be sent to terminal, therefore, server at least obtains two image datas, and is sent to terminal, often by least two link
The image data that individual chain receives and sends, is based on the image data obtained from the picture required parameter that this link receives；This is the most real
Executing in example, this server process each picture required parameter is independent, and therefore, each between terminal with server links
Being all separate, the mark of corresponding each image data, a link is served only for transmitting a picture required parameter and depending on
The image data obtained according to this picture required parameter.
