[embodiment]
Basic thought of the present invention is: when mobile terminal received the request of Client-initiated Image Display, the second definition according to the second picture data of the first definition of the first image data to be shown and current demonstration, generated the definition running parameter; Described mobile terminal sends to server by described definition running parameter; The described server of described mobile terminal reception from complete image data, extracting pixel, utilizes the 3rd image data of the pixel generation of extracting according to described definition running parameter; The 3rd image data that described mobile terminal will be received and described second picture data merge, and generate described the first picture number.
In order to make the purpose, technical solutions and advantages of the present invention clearer, describe the present invention below in conjunction with the drawings and specific embodiments.
The invention provides a kind of picture transmission method, it is the processing method that the present invention realizes mobile terminal side in picture transmission method, Fig. 1 is the schematic flow sheet that the present invention realizes the preferred embodiment one of picture transmission method, and as shown in Figure 1, the preferred embodiment comprises the following steps:
Step S101, when mobile terminal receives the request of Client-initiated Image Display, the second definition according to the second picture data of the first definition of the first image data to be shown and current demonstration, generate the definition running parameter, and described definition running parameter sent to server.
Concrete, when the user enters the interface Showed Picture of mobile terminal first, in interface, Show Picture, mobile terminal is to receive for the first time the Image Display request, after as the user, entering into the interface Showed Picture, while clicking picture shown in interface, mean that the user asks to obtain the image data higher than the definition of the image data of current demonstration, mobile terminal is received the Image Display request for this image data at every turn; The image data shown can be the picture in news, streetscape picture in map or the picture in Search Results etc.
When mobile terminal was received the Image Display request for certain image data, the second definition according to the second picture data of the first definition of the first image data to be shown and current demonstration, generated definition running parameter R, described definition running parameter
The definition running parameter equals the difference of the second definition of the second picture data of the first definition of the first image data to be shown and current demonstration, namely
Wherein, described the first definition
Described the second definition
Therefore according to the second definition of the second picture data of current demonstration, can determine k
n, can set in advance step value, k
N+1Equal k
nAdd step value, k
N+1Span be to be greater than k
nAnd be less than or equal to the arbitrary integer in the k scope; Wherein, 1≤k≤min (M, N).For example, M equals 10, N and equals 11, min (M, N)=10, and k can get any one numerical value in 1 to 10, and for example k equals 5.
Generally, while receiving for the first time the Image Display request, can be to the lower image data of server request definition, namely when to server, sending the definition running parameter for the first time, the second definition of the second picture data of current demonstration
The definition of image data that means current demonstration is minimum, wherein, and k
1Value can set in advance default value, make k
1Have initial value f, wherein, the value of k need to set in advance, and the value of k is repeatedly immobilizing in picture transmission request.
In the present invention, the definition running parameter R sent to server is decimal data, this decimal data can be converted into binary data, namely by binary data, mean the readability of the picture of asking, as 00 ... 00 binary data means that definition is minimum, and the pixel of the image data of request is 12 of complete image data
M+N-2k11 ... 11 binary data means that definition is the highest, and the image data of request is complete image data, 00 ... 1 ... the l position of 00 binary data is 1, other are all 0, and the pixel of the image data of asking so is 12 of complete image data
k-l, the definition R=(2 of the image data of request
L+1-2
l, k), the k in definition running parameter R means to transform the data amount check in the binary data obtained; And, mobile terminal is to the server request image data time, need to be according to order request from low to high, namely first ask the image data that definition is low, ask again the image data that definition is high, for example, first ask binary data 000 ... 00111 ... 11100 ... the namely front j of 0(position is 0, middle i position is 1, rear k-j-i position is 0) image data of represented readability, ask again binary data 11 ... 11000 ... 000(namely before the j position be 1, rear k-j position is 0) image data of represented readability.
Mobile terminal, after generating the definition running parameter, sends picture transmission request to server, wherein carries the definition running parameter of generation and the sign of request image data.
Step S102, the described server of described mobile terminal reception from complete image data, extracting pixel, utilize the 3rd image data of the pixel generation of extracting according to described definition running parameter.
The 3rd image data that step S103, described mobile terminal will receive and described second picture data merge, and generate described the first image data.
Concrete, mobile terminal is after receiving that from server the definition running parameter is the 3rd image data of R, mobile terminal merges the 3rd image data and second picture data, generates the first image data to be shown, by the method for the 3rd image data and the merging of second picture data is:
Mobile terminal, when from server, obtaining image data for the first time, just creates one 2
M* 2
Nmatrix M t, matrix M t has had previously obtd image data, mobile terminal is filled into the image data of this acquisition the relevant position of this matrix, filling process is exactly the inverse process that server extracts pixel, namely according to the definition running parameter R in this picture transmission request, obtain binary data, then according to low level, to high-order order, binary data is traveled through, the l bit data traversed is 0 o'clock, continue traversal, the l bit data traversed is 1 o'clock, need to be to filler pixels in matrix M t, during filler pixels, first take the 0th position in matrix M t is starting point, with 2
k-lfor interval, determine the abscissa of the position need filler pixels, then take the 0th position in matrix M t and be starting point, with 2
k-lfor interval, determine the ordinate of the position that needs filler pixels, thereby determine the position of pixel in matrix M t, by that analogy, obtain the position of all pixels in matrix M t, then, by the pixel filling in the 3rd image data to these positions in matrix M t, during filler pixels, first from first pixel the pixel of receiving, start to extract successively pixel, the pixel filling that then will extract according to default processes pixel order is to relevant position, after all being filled into all pixels of receiving in matrix M t, remove the part be not filled in matrix M t, utilize the pixel of the part be filled to form image data.
Mobile terminal need to show the first image data obtained after merging, if the user has higher requirement to the definition of the first image data, can continue to click picture, in order to mobile terminal, to initiate the demonstration request of picture, after mobile terminal receives this Image Display request, the definition r that needs judgement the first image data, if the definition r=(2 of this first image data
k-1, k), the definition that means the first image data equals the definition of complete image data, has namely reached the peak of definition; If the definition of the first image data is less than r=(2
k-1, k), mean to also have the higher image data of definition, therefore, execution step S101, mobile terminal continue to send picture transmission request to server, in order to the higher image data of server request definition, to meet consumers' demand; For example, if the definition of the first image data is r=(11111,5), be converted into decimal data by 11111, obtain r=(2
5-1,5), namely the definition of the first picture equals the definition of complete image data, and the user clicks the first image data again and can not triggering mobile terminals obtain image data more clearly from server.
For example, when mobile terminal obtains definition, be 000 ... 00111 ... 11100 ... the j position is 0 before 0(, and middle i is for being 1, and finally the k-j-i position is 0) image data I
2The time, by image data I
2With the definition of receiving before be 111 ... 11000 ... the j position is 1 before 000(, and rear k-j position is 0) image data I
1Merge, generating definition is 111 ... 111 ... 11100 ... the j+i position is 1 before 0(, and rear k-j-i position is 0) image data I
3The merging method is: according to the binary data 111 of the definition running parameter generated for the first time ... 11000 ... 000, obtain image data I
1In the position of all pixels in matrix M t, then by image data I
1In all pixel fillings in matrix M t; Again according to the binary data 000 of the definition running parameter generated for the second time ... 00111 ... 11100 ... 0, obtain image data I
2In the position of all pixels in matrix M t, by image data I
2In all pixel fillings in matrix M t, finally remove the part be not filled in matrix M t, utilize the pixel generating pictures data I of the part filled
3.
