Background technology
Along with the continuous development of IT technology, the price of computer peripherals such as scanner and all-in-one multifunctional machine constantly reduces, and is more and more universal in the personal user.The personal user is after having bought the said equipment, and the papery photo that mostly has hope to take before will be own is imported computer by scan mode, deposits, appreciates, processes with the calculating organizational security then or send to other people.
For using flat bed scanner or having the user of the all-in-one multifunctional machine of flat-bed scanning unit, when the scanning multiple pictures, in order to raise the efficiency, usually multiple pictures is placed on the flat board of scanning device simultaneously, is same image file with scanning software with all photo scannings, uses then such as image editing software, as PHOTOSHOP etc., photo content in the original picture file is sheared out one by one, save as the independently image file of single photo content at last.
This process has many shortcomings: as require the user must learn to use image editing softwares such as PHOTOSHOP; From the original picture file that comprises all photos unique file is sheared out and saved as to every photos one by one, this repetitive operation is very loaded down with trivial details; The user is difficult to put photo horizontal vertically flatly on smooth scanning flat board, can increase the operation of rotary fine adjustment like this when the successive image editor, and this operation is also very loaded down with trivial details; When the user puts photo on the scanning flat board, differ each time and put the photo of maximum quantity surely, thereby reduced the efficient of scan operation.
Just because of above reason, there is considerable user to be unwilling to adopt the method for single pass multiple pictures, but would rather scan one by one, and photo of every like this scanning all to open scanner cover plate, put photo, cover cover plate, start preview function, choose image border, formally scan, open cover plate, change photo, its operation is equally very loaded down with trivial details, and efficient is very low.
In United States Patent (USP) 5483325, once mentioned a kind of convenient annex framework that uses photocopier to duplicate (or scan with flat bed scanner) multiple name cards.But this invention only can make things convenient for the user to put business card, do not mention the size and the positional information of additional empty frame on template, the problem of plurality of pictures being divided out automatically from original scanning result with the dedicated program that has the empty frame size positions of template information when also not mentioning scanning, the user still needs own each image content of dividing from original picture.This framework is adsorbed on the photocopier glass plate with electrostatic film in addition, need make hypotenuse at the edge of hollow out frame, makes complicated; This invention is not mentioned and how to be made things convenient for the user to pick and place the method for template; The problem that optimizes the arrangement of of frame is not proposed yet.
In United States Patent (USP) 6177982, once mentioned a kind of dentist of convenience and used flat bed scanner to carry out the template of dentistry X-ray film scanning.The method of plurality of pictures being divided out from original scanning result with the Automatic Program that has the empty frame size positions of template information when but scanning is not mentioned in this invention, the user still needs own each image content of dividing from original picture.In addition, do not mention the problem that optimizes the arrangement of of frame yet; Do not mention and make things convenient for the user to pick and place the design of template.
In United States Patent (USP) 6292596, once mentioned a kind of method of utilizing dedicated templates scanning small-size film and scanning result being made digitized processing.But the method for plurality of pictures being divided out from original scanning result with the Automatic Program that has the empty frame size positions of template information when this patent is not mentioned scanning, the user still needs own each image content of dividing from original picture.
Present some scanner lays claim to the photo scanning pattern on the market, under this pattern, the user can be scanned dull and stereotyped enterprising line scanning to multiple pictures with arbitrarily angled being placed in, software comes out each photo boundary demarcation automatically and adjusts angle, and the user can obtain adjusting the independently image file of angle.But this mode has following three shortcomings: the first, and requiring must have enough spacings between the photo, otherwise software can't distinguish them.This requirement can reduce the efficient that photo is put.For example, the maximum scan zone of ordinary flat scanning device is 216 * 297mm (8.5 * 11.7 inches) at present, for 88.9 the most general * 127mm of present application (3.5 * 5 inches) photo, between each photo spacing is arranged if require, in above-mentioned zone, can only put 3 at most; And if continuously apart from put and photo between not overlapping, in above-mentioned area, can put 5.The second, the software programming complexity.Said method requires software to carry out automatic recognition image border and adjusts the complicated calculations of visual angle automatically, for the scanning software developer, has increased the difficulty of work undoubtedly.The 3rd, amount of calculation is big, the speed of influence scanning.

Embodiment
In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention is further described below in conjunction with the drawings and specific embodiments.
Specific embodiment 1:
In order to realize method of the present invention, can the scanner of scanned photograph be improved, promptly on the scanning flat board of scanner, add the photo sign.Referring to Fig. 1, Fig. 1 is a dull and stereotyped schematic diagram of scanning with scanner of two kinds of sizes (88.9 * 127mm (3.5 * 5 inches)/101.6 * 152.4mm (4 * 6 inches)) photo sign.As can be seen from Figure 1, on the frame 1 of scanning flat board, indicate following sign: former dot mark 10, put the used group mark 51,52,53,54,55,56 of 88.9 * 127mm (3.5 * 5 inches) photo, and put the used group mark 61,62,63,64 of 101.6 * 152.4mm (4 * 6 inches) photo.Wherein the position distribution of each group mark has satisfied not overlapping requirement of putting photo as much as possible on the scanning flat board, and guarantees that photo has at least a limit to abut against the requirement that scans on the dull and stereotyped frame.
Fig. 2 has illustrated the arrangement method when use the present invention scans 88.9 * 127mm (3.5 * 5 inches) photo, as shown in the figure, puts the photo of five 88.9 * 127mm (3.5 * 5 inches) respectively according to sign 51,52,53,54,55,56; Fig. 3 has illustrated the arrangement method when use the present invention scans 101.6 * 152.4mm (4 * 6 inches) photo, as shown in the figure, puts the photo of three 101.6 * 152.4mm (4 * 6 inches) respectively according to sign 61,62,63,64.
Below in conjunction with Fig. 2, Fig. 3 and Fig. 4, be example to scan 101.6 * 152.4mm (4 * 6 inches) photo, describe the method for scanned photograph of the present invention in detail.Fig. 4 is the method according to the scanned photograph of the embodiment of the invention 1, and as can be seen from Figure 4, this method comprises the steps:
Step 401: the positional information that the different size photo of being determined by each group mark on the scanning flat board that prestores in scanning software is put every photo of pattern correspondence.
The pattern of putting with 101.6 * 152.4mm (4 * 6 inches) photo is an example, as can be seen from Figure 3, and when the user puts photo according to sign, by coordinate points 611 (0,0), 612 (4,0), 613 (0,6), the rectangular area of 614 (4,6) formation is photo 61 regions; The rectangular area that is made of coordinate points 621 (4,0), 622 (8,0), 623 (4,6), 624 (8,6) is photo 62 regions; The rectangular area that is made of coordinate points 631 (0,6), 632 (6,6), 633 (0,10), 634 (6,10) is photo 63 regions, and coordinate unit is an inch in the present embodiment.As characteristic point, its geometric coordinate is pre-stored in the scanning software with above each coordinate points, as the foundation of automatic division 101.6 * 152.4mm (4 * 6 inches) photo.
Step 402: the user puts photo 61,62,63 by method shown in Figure 3.
Step 403: start scanning software, the prompting user selects whether to use " scanning multiple pictures pattern ", if user's selection is then to forward step 404 to; Otherwise enter the conventional sweep flow process, promptly at first start prescan, scanning area and the sweep parameter of selecting according to the user scans and obtains single image file then, preserves this single image file at last.
Step 404: the prompting user selects the size of scanned photograph.
If the user selects 88.9 * 127mm (3.5 * 5 inches) photo size, then 88.9 * 127mm (3.5 * 5 inches) photo of prestoring of invocation step 401 is put the pattern corresponding position information; If the user selects 101.6 * 152.4mm (4 * 6 inches) photo size, then 101.6 * 152.4mm (4 * 6 inches) photo of prestoring of invocation step 401 is put the pattern corresponding position information.
In the present embodiment, the user selects 101.6 * 152.4mm (4 * 6 inches) photo size, then calls 101.6 * 152.4mm (4 * 6 inches) photo and puts the pattern corresponding position information.
Step 405: the prompting user selects to scan required resolution and scanning figure place.
The unit of resolution is DPI (Dots Per Inch), and what promptly per inch comprised counts, and a point is a pixel, so the number of picture elements that resolution is per inch to be comprised.For example, 300DPI represents that per inch comprises 300 number of picture elements.
The scanning figure place is that each pixel takies figure place.For example, if the scanning figure place is 24 colours, then each pixel takies 24, i.e. 3 bytes.
Step 406: scanner scans whole scanning area according to the resolution and the scanning figure place of user's input, obtains single image file.
It at first is single image file distribute data buffer area.
Each pixel of scanning gained is stored in the data buffer area of distributing into single image file, the storage of this single image file is to begin to store line by line pixel from scan origin, that is to say, in data buffer area, store the first row pixel earlier, store the second row pixel then, by that analogy, until having stored last column pixel.When the pixel of the every row of storage, this row of storage is stored the pixel of this row on secondary series then at first pixel that lists earlier, by that analogy, and until having stored this row pixel that lists in the end.
For example, the dull and stereotyped scanning area of known scanning is 8.5 * 11.7 inches, if resolution is 300DPI, the scanning figure place is 24 chromoscans, the dull and stereotyped transverse width of scanning is 8.5 inches, so every row has 300 * 8.5=2550 pixel, the dull and stereotyped vertical width of scanning is 11.7 inches, so every row have 300 * 11.7=3510 pixel.Because each pixel is 24, i.e. 3 bytes, so per 2550 * 3=7650 byte is a data line in the single image file, per 3510 * 3=10530 byte is a columns certificate.
Step 407: the image file that obtains according to size, resolution and the scanning figure place partiting step 406 of the scanned photograph of user input.
Disposing way with 101.6 * 152.4mm shown in Figure 3 (4 * 6 inches) photo is an example, if resolution is 300DPI, the scanning figure place is 24 chromoscans, divides every photo as follows:
At first be respectively each photo 61,62 and 63 data buffer area of distributing image file.
For photo 61, be coordinate with the pixel, coordinate points 611 (300 * 0,300 * 0) then, 612 (300 * 4,300 * 0), the position of photo 61 is determined in 613 (300 * 0,300 * 6) and 614 (300 * 4,300 * 6).With the transverse width is X-axis, is Y-axis, then ((Y with vertical width
611+ i) * 2550+X
611+ 1) to ((Y
611+ i) * 2550+X
612) individual pixel is the pixel of photo 61, wherein i is to (Y from-1
613-Y
611-1) integer.So, the 1st to 1200 the 1st line data that pixel is a photo 61 in the single image file; (2550+1) to (2550+1200) individual pixel is the 2nd line data of photo 61, and by that analogy, (2550 * (1800-1)+1) to (2550 * (1800-1)+1200) individual pixel is last column data of photo 61.Because each pixel takies 3 bytes, the 1st to 3600 byte in the then single image file is the 1st line data of photo 61; (7650+1) to (7560+3600) byte is the 2nd line data of photo 61, and by that analogy, (7650 * (1800-1)+1) to (7650 * (1800-1)+3600) byte is last column data of photo 61.
For photo 62, be coordinate with the pixel, then the position of photo 62 is determined in coordinate points 621 (300 * 4,300 * 0), 622 (300 * 8,300 * 0), 623 (300 * 4,300 * 6), 624 (300 * 8,300 * 6).With the transverse width is X-axis, is Y-axis, then ((Y with vertical width
621+ i) * 2550+X
621+ 1) to ((Y
621+ i) * 2550+X
622) individual pixel is the pixel of photo 62, wherein i is to (Y from-1
623-Y
621-1) integer.So (1200+1) to (1200+1200) the individual pixel in the single image file is the 1st line data of photo 62; (2550+1200+1) to (2550+1200+1200) individual pixel is the 2nd line data of photo 62, and by that analogy, (2550 * (1800-1)+1200+1) to (2550 * (1800-1)+1200+1200) individual pixels are last column data of photo 62.Because each pixel takies 3 bytes, (3600+1) to (3600+3600) byte in the then single image file is the 1st line data of photo 62; (7560+3600+1) to (7560+3600+3600) byte is the 2nd line data of photo 62, and by that analogy, (7650 * (1800-1)+3600+1) to (7650 * (1800-1)+3600+3600) bytes are last column data of photo 62.
For photo 63, be coordinate with the pixel, then the position of photo 63 is determined in coordinate points 631 (300 * 0,300 * 6), 632 (300 * 6,300 * 6), 633 (300 * 0,300 * 10), 634 (300 * 6,300 * 10).With the transverse width is X-axis, is Y-axis, then ((Y with vertical width
631+ i) * 2550+X
631+ 1) to ((Y
631+ i) * 2550+X
632) individual pixel is the pixel of photo 63, wherein i is to (Y from-1
633-Y
631-1) integer.So (2550 * 1800+1) to (2550 * 1800+1800) individual pixels are the 1st line data of photo 63 for in the single image file; (2550 * (1800+1)+1) to (2550 * (1800+1)+1800) individual pixel is the 2nd line data of photo 63, by that analogy, (2550 * (1800+1200-1)+1) to (2550 * (1800+1200-1)+1800) individual pixel is last column data of photo 63.Because each pixel takies 3 bytes, (7650 * 1800+1) to (7650 * 1800+5400) bytes are the 1st line data of photo 63 for in the then single image file; (7560 * (1800+1)+1) to (7560+ (1800+1)+5400) byte is the 2nd line data of photo 63, by that analogy, (7650 * (1800+1200-1)+1) to (7650 * (1800+1200-1)+5400) byte is last column data of photo 63.
The data of photo 61,62 and 63 correspondences are copied to respectively in the data buffer area of image file separately.
Step 408: step 407 is divided each image file that comes out discern, surpass the number of picture elements proportion threshold value of setting if judge the ratio of quantity and image pixel sum of the pixel of the pixel threshold value that is lower than setting in the image file, illustrate that then this image file does not have content; Otherwise illustrate that this image file is meaningful.
Each pixel of image file has pixel value separately, the pixel value of a little higher than scanning background of setting of pixel threshold value, if the number of picture elements ratio of setting is 90%,, represent that then this image file does not have content if the pixel value of the pixel more than 90% of an image file is lower than the pixel threshold value so.
Step 409: the image file that will not have content is given up.
Step 410: prompting user-in file name and storage directory, and filename and the storage directory imported according to the user save image file.
Above embodiment is that the disposing way with 101.6 * 152.4mm shown in Figure 3 (4 * 6 inches) photo is an example, in practice, can carry out photo scanning at different situations with same thinking, for example, change the aligning method of photo and the position of sign thereof, perhaps, put efficient for raising the different size photo is mixed placement.

Below in conjunction with Fig. 6 and Fig. 7, be example to scan 127 * 177.8mm (5 * 7 inches) photo, describe the method for scanned photograph of the present invention in detail.Fig. 7 is the method according to the scanned photograph of the embodiment of the invention 2, and as can be seen from Figure 7, this method comprises the steps:
Step 701: positional information, the positional information of template model distinguishing mark and the color of recognition template sign of every photo determining by each group mark on the scan templates that in scanning software, prestores.
For picture location information, as shown in Figure 6, the rectangular area of 4 formations of 311-314 of template 1 is photo 31 regions, and the rectangular area of 4 formations of 321-324 is photo 32 regions.If with summit, the scanner lower left corner 21 is the origin of coordinates, the coordinate of each coordinate points is so: 311 (19.1,297), 312 (19.1,170), 313 (196.9,170), 314 (196.9,297); 321 (19.1,148.5), 322 (19.1,21.5), 323 (196.9,21.5), 324 (196.9,148.5), here, coordinate unit is a millimeter.More than each coordinate points as the characteristic point of picture location, its geometric coordinate is pre-stored in the scanning software.
For the positional information of template model distinguishing mark, by the size of template model distinguishing mark and position as can be known, the zone that coordinate points (0,20), (0,30), (10,30), (10,20) constitute is template model distinguishing mark 121 regions; The zone that coordinate points (0,10), (0,20), (10,20), (10,10) constitute is template model distinguishing mark 122 regions; The zone that coordinate points (0,0), (0,10), (10,10), (10,0) constitute is template model distinguishing mark 123 regions, and here, coordinate unit is a millimeter.More than each coordinate points as the characteristic point of template model distinguishing mark, its geometric coordinate is pre-stored in the scanning software.
The color combination of the template model distinguishing mark of template 1 is: 121-is black, 122-is white, 123-is white.
Step 702: the user at first will be placed on template on the scanning flat board, note having one of sign to face down, placing direction when placing direction will be with coordinates computed is consistent, and template will lie in the dull and stereotyped frame of scanning, and the user is placed on photo 31 and 32 in the frame 111 and 112 of template 1 then.
Step 703: start scanning software, the prompting user selects whether to use " scanning multiple pictures pattern ", if user's selection is then to forward step 704 to; Otherwise enter the conventional sweep flow process.
Step 704: the prompting user selects to scan required resolution and scanning figure place.
Step 705: scanner scans whole scanning area according to the resolution and the scanning figure place of user's input, obtains single image file.
It at first is single image file distribute data buffer area.
Each pixel of scanning gained is stored in the data buffer area of distributing into single image file, the storage of this single image file is to begin to store line by line pixel from scan origin, that is to say, in data buffer area, store the first row pixel earlier, store the second row pixel then, by that analogy, until having stored last column pixel.When the pixel of the every row of storage, this row of storage is stored the pixel of this row on secondary series then at first pixel that lists earlier, by that analogy, and until having stored this row pixel that lists in the end.
For example, the dull and stereotyped scanning area of known scanning is 8.5 * 11.7 inches, if resolution is 300DPI, the scanning figure place is 24 chromoscans, the dull and stereotyped transverse width of scanning is 8.5 inches, so every row has 300 * 8.5=2550 pixel, the dull and stereotyped vertical width of scanning is 11.7 inches, so every row have 300 * 11.7=3510 pixel.Because each pixel is 24, i.e. 3 bytes, so per 2550 * 3=7650 byte is a data line in the single image file, per 3510 * 3=10530 byte is a columns certificate.
Step 706: judge the result that corresponding position is discerned in single image file of template model distinguishing mark 121,122 and 123 in the single image,, then forward step 710 to if unidentifiedly go out sign; Otherwise, determine the template model according to the color combination of the template model distinguishing mark that identifies.
In the present embodiment, the zone at template model distinguishing mark 121 places is a black, and the zone at template model distinguishing mark 122 and 123 places is a white, can determine that then this template is the template of 127 * 177.8mm (5 * 7 inches) photo, be template 1, the positional information of every photo determining of the template that prestores of invocation step 701 1 then.
Step 707: the image file that the scanning resolution of the template model that identifies according to step 706, user's input and scanning figure place partiting step 705 obtain.
Disposing way with 127 * 177.8mm shown in Figure 6 (5 * 7 inches) photo is an example, if resolution is 300DPI, the scanning figure place is 24 chromoscans, divides every photo as follows:
