i(i=1,2,3...n), wherein n is the number of pages of described pending data image.
S22, open described scan-data image G
i(i=1,2,3...n), wherein n is the number of pages of described pending data image.
S23, successively scan-data image G described in reading current page
ithe RGB information of each display point position on effective coverage, and by described second transformation rule, the RGB information of described display point position is converted to binary-coded character.
Wherein, data image G is determined
ieffective coverage has been come by the mode reading location pattern.
In this embodiment, second transformation rule is specially: judge interval if the rgb value of described display point position is positioned at described first pigment point, then judge to scan the first pigment point, produce character 1 to export, if the rgb value of described display point position is positioned at described second pigment and judges interval, then judge to scan the second pigment point, produce character 0 to export, if the rgb value of described display point position is positioned at described 3rd pigment point and judges interval, then judge to scan the 3rd pigment point, represent and scan end mark.
If S24 described scan-data image G
ithe RGB information of each display point position converts, and does not read described end mark, then open scan-data image G described in lower one page
i+1, and repeat step S23;
If S25 reads end mark, then end data image recognition transfer process exiting.
Wherein, Fig. 4 is that in the present embodiment, data image second identifies transfer process schematic diagram, and as can be known from Fig. 4, this data image identification transfer process can also realize in mode synchronous below:
S21, obtain by the image capture device of described second terminal the data image that the screen of described first terminal shows after, generate scan-data image G
i(i=1,2,3...n), wherein n is the number of pages of described pending data image.
S22, open described scan-data image G
i(i=1,2,3...n), wherein n is the number of pages of described pending data image.
S221, simultaneously scan-data image G described in reading current page
ithe RGB information of each display point position on effective coverage, and by described second transformation rule, the RGB information showing some positions described in each is converted to binary-coded character simultaneously.
Wherein, data image G is determined
iwith data image first, effective coverage mode identifies that the related notion in transfer process is identical with the second transformation rule, described in before specifically seeing.
If S222 does not read described end mark, then open scan-data image G described in lower one page
i+1, and repeat step S221.
If S223 reads end mark, then end data image recognition transfer process exiting.
