Description

  The present invention relates to generation of a two-dimensional code, and particularly relates to a two-dimensional code generation system and a two-dimensional code generation program for regenerating a two-dimensional code and transferring data to a printing apparatus.

  In recent years, barcodes have been widely used in the world. Among them, the use of two-dimensional codes is widespread due to the large amount of information that can be expressed (see Patent Documents 1 and 2). For example, by converting the description of a paper document into a two-dimensional code and adding the two-dimensional code to the margin of the paper document, when the paper document is scanned, the barcode is recognized and decoded. Then, it is possible to acquire the description content of the document as electronic data without using OCR or the like.

  Here, the two-dimensional code has a larger amount of information that can be expressed than the one-dimensional code (barcode), but the amount of information is still limited. When a large amount of information is represented by barcodes, there is a way to divide the information into multiple barcodes (see JIS-X-0510, p22, 5.3.2.7, concatenation mode).

(Generate multiple QRs and place them on one page)
Hereinafter, the invention will be described by taking a QR code as a representative example of a two-dimensional code as an example. That is, in the QR code connection mode, a plurality of QR codes are generated, and at this time, a plurality of QR codes having the same model number are generated. At this time, since the QR code has the same model number, it is usually generated with the same size QR code.

  In addition, when decoding a plurality of QR codes in the connection mode, since it is necessary to read all the plurality of QR codes, the plurality of QR codes are arranged and output on one sheet of paper.

(QR generation output made on PC)
These QR code generation environments may be used for outputting forms from the core host, but recently, QR codes are often generated easily on a PC. A QR code can be easily created by generating QR code with an application on a PC and placing (pasting) it on the page of an electronic document created by the document creation software. .

(Procedure for detecting multiple QRs)
Then, the paper on which the plurality of QR codes are arranged is scanned, each QR code is recognized and decoded, and connected to return the result.

  Hereinafter, a process when detecting and decoding a plurality of QR codes will be described. There are three position element patterns in the QR code. To detect a QR code from an image, first, the entire image is scanned to detect a position element pattern, and all center coordinates of the position element pattern are calculated (see JIS-X-0510, p65 to p66). . For example, if there is one QR code, the center coordinates of the position element pattern are calculated as three, and if there are four QR codes, the center coordinates of the position element pattern are calculated as 3 × 4 = 12.

  As shown in FIG. 14, the position element pattern includes a position detection pattern # 0 in the upper left, a position detection pattern # 1 in the upper right, and a position detection pattern # 2 in the lower left. Then, a right-angled isosceles triangle having the centers of these position element patterns # 0, # 1, and # 2 as vertices is formed, and the vertical position and rotation of the two-dimensional code are detected.

JP-A-6-12515 Japanese Patent No. 2938338

(Unnecessary right isosceles triangle)
However, when a plurality of QR codes exist, if a right isosceles triangle is detected from the position detection pattern as a condition for detecting the QR code, a right isosceles triangle is found at an unnecessary position (see FIG. 15). That is, a right isosceles triangle that is misrecognized appears.

  At this time, even if an unnecessary right isosceles triangle is found, it is possible to exclude the unnecessary triangle from the whole triangle combination. For example, in the overall configuration including unnecessary triangles, it is possible to eliminate it by utilizing the fact that there are excess points. However, in this process, the calculation is repeated endlessly until the optimum combination is obtained. As a result, the amount of calculation increases, and the processing speed becomes slow.

  In addition, since an unnecessary right isosceles triangle is determined to be a QR code, there is a problem that erroneous recognition of the QR code occurs.

  Furthermore, when a QR code is pasted on an electronic document created on a personal computer and printed on paper, the QR code pasted on the personal computer may be fine and not accurately reproduced on paper. In this case, the QR code is not normally decoded even if this paper is scanned.

  In addition, when a QR code is pasted on an electronic document on a personal computer, the QR code image may be pasted in an enlarged or reduced manner in order to improve the appearance of the electronic document. A QR code image needs high black and white binary contrast, but the contrast is lowered due to the enlargement or reduction of the QR code image, and the black and white binary image is blurred by enlargement / reduction image edge interpolation processing. There is. In this case, there is a problem that the QR code is not normally decoded even if the paper is printed in this state and the paper is scanned.

  The present invention has been made to solve such problems. That is, according to the present invention, when transferring a file with a two-dimensional code to a printing apparatus, an acquisition unit that acquires drawing data of the two-dimensional code, and a decoding of the two-dimensional code based on the drawing data acquired by the acquisition unit. A decoding unit for performing, a two-dimensional code generating unit for generating a new two-dimensional code according to the resolution of the printing apparatus from information obtained by decoding by the decoding unit, and a new one for generating the drawing data by the two-dimensional code generating unit This is a two-dimensional code generation system comprising drawing data generation means for replacing the drawing data of a two-dimensional code.

  In the present invention, when transferring a file with a two-dimensional code to a printing apparatus, decoding from the drawing data of the two-dimensional code, generating a new two-dimensional code according to the resolution of the printing apparatus, Since the portion corresponding to the two-dimensional code of the original drawing data is replaced with the drawing data of the new two-dimensional code, the two-dimensional code can be regenerated in a form that is easy to detect according to the resolution of the printing apparatus.

  Further, the present invention provides an acquisition unit that acquires drawing data of a plurality of two-dimensional codes and a plurality of two-dimensional codes acquired by the acquisition unit when transferring a file with a plurality of two-dimensional codes to the printing apparatus. A two-dimensional code comprising drawing data generation means for generating new drawing data for dividing a plurality of two-dimensional codes for drawing data, and transfer means for transferring the new drawing data generated by the drawing data generation means to the printing apparatus Generation system.

  In the present invention, when transferring a file with a plurality of two-dimensional codes to a printing apparatus, the two-dimensional code is regenerated in a form that can clearly distinguish the plurality of two-dimensional codes. Even when a plurality of two-dimensional codes are attached to the medium printed in (1), these can be accurately distinguished and detected.

  In addition, by realizing the above two-dimensional code generation method by program processing, it can be applied to a program (for example, a printer driver) having various functions for transferring a two-dimensional code to a printing apparatus and various electronic devices (printer controllers). Become. Here, examples of the two-dimensional code include QR code, PDF417, maxi code (Maxi Code), and data matrix (Data Matrix), and characteristics of the two-dimensional code (for example, the QR code is a minimum pixel unit). By performing noise removal according to the module size), it is possible to realize noise removal that does not affect the drawing contents of the two-dimensional code.

  Therefore, according to the present invention, it is possible to shorten the detection processing time of the two-dimensional code and improve the detection accuracy of the two-dimensional code.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the present embodiment, a QR code is taken as an example of a two-dimensional code. FIG. 1 is a block diagram illustrating a configuration of a two-dimensional code generation system according to the present embodiment. That is, the two-dimensional code generation system is realized by a printer driver or a printer controller. The acquisition unit 1, the two-dimensional code decoding unit 2, the two-dimensional code generation unit 3, the drawing data generation unit 4, and the transfer unit 5 are provided. I have.

  The acquisition unit 1 performs processing for acquiring drawing data of a two-dimensional code from a file created by application software. The two-dimensional code decoding unit 2 decodes the two-dimensional code based on the drawing data acquired by the acquisition unit 1. The two-dimensional code generation means 3 performs a process of generating a new two-dimensional code corresponding to the resolution of the printing apparatus from the information obtained by decoding. The drawing data generation unit 4 replaces the corresponding portion of the original drawing data with the new two-dimensional code generated by the two-dimensional code generation unit 3, and the acquisition unit 1 generates a plurality of two-dimensional codes. When drawing data is acquired, a process for generating new drawing data for dividing a plurality of two-dimensional codes is performed. The transfer unit 5 performs a process of transferring new drawing data generated by the drawing data generation unit 4 to the printing apparatus.

  Next, the process by the two-dimensional code generation system will be specifically described as an embodiment.

  FIG. 2 is a flowchart illustrating the first embodiment. The first embodiment is characterized in that when a file with a two-dimensional code is transferred to a printing apparatus, a QR code is recreated (regenerated) according to the printer resolution so that it can be easily detected.

  First, drawing data is acquired from application software executed on a personal computer or the like (step S11), and the drawing data is rasterized in accordance with the resolution of the printer (step S12). Next, a QR code decoding process is performed on the raster image (step S13).

  Next, in consideration of the decoding result and the resolution of the printer, the QR code is encoded again (step S14), and the corresponding portion of the two-dimensional code of the original raster image is replaced with a newly generated QR code image (step S15). ). Then, the raster image with the new QR code is transferred to the printer, and a print instruction is given (step S16).

  The processing in each of the above steps is executed by the printer driver, but may be executed by a printer controller inside the printer. FIG. 3 is a flowchart for explaining processing in the printer controller.

  First, page description language data is acquired from a personal computer as a client (step S21), and the page description language data is rasterized (step S22). Next, a QR code decoding process is performed on the raster image (step S23).

  Next, the QR code is encoded again in accordance with the decoding result and the printer characteristics such as the printer resolution (step S24), and the two-dimensional code corresponding part of the original raster image is replaced with the newly generated QR code image (step S25). ). Then, print output is performed using the raster image to which the new QR code is attached (step S26).

  Here, as a specific QR code regeneration, the lower the printer resolution, the larger the original QR code module size (configuration unit), or the lower the printer resolution, the larger the original two-dimensional code size. It is possible to enlarge it. If the resolution of the printer is low, reproducibility deteriorates with a small module size. Therefore, even if the QR code is printed out with a low resolution printer by using a large module size or increasing the area of the two-dimensional code itself, it is sufficient. Can be detected.

  Also, the original QR code is decoded, and the module size may be smaller than necessary depending on the amount of the decoded information. In such a case, if a new QR code is generated by changing to a necessary and sufficient module size according to the amount of decoded information, even a QR code printed out by a low resolution printer can be detected sufficiently. Become.

  Next, a second embodiment will be described. The second embodiment is characterized in that when a plurality of QR codes are arranged, a boundary line is added between the QR codes and rearranged so as to be easily detected. FIG. 4 is a schematic diagram illustrating an example in which a boundary line is inserted between a plurality of QR codes. That is, as shown in FIG. 4A, when, for example, two QR codes are arranged as an original document, drawing data of these QR codes is acquired, and a boundary line between the two QR codes in the drawing data is obtained. To generate new drawing data. FIG. 4B shows an example in which a black border is added between two QR codes.

  In this way, by adding a boundary line between two QR codes, when the QR code is decoded by reading the printed medium, the two QR codes are reliably separated by detecting the boundary line. Can be read. In FIG. 4B, a black boundary line is added. However, the boundary line may be configured with a color that is difficult to be seen by human eyes and can be read by a scanner. The example shown in FIG. 4C is an example in which a yellow boundary line is added. In addition, in FIG.4 (c), the yellow boundary line is shown with the broken line. As a result, the two QR codes can be reliably divided without deteriorating the appearance of the print output.

  FIG. 5 is a flowchart illustrating a process for detecting a plurality of QR codes having boundary lines. This detection process is executed by an electronic device that reads an image of a QR code and decodes the image.

  First, boundary line conditions (for example, color and minimum length) are specified (step S301), and boundary lines are extracted from the read image (step S302). This boundary line extraction uses a general line segment extraction technique of image processing.

  Next, the center coordinates of the QR code position detection pattern are detected from the read image (step S303). This detection method uses the method described in JIS-X-0510, p65-p66, which shows the detection method of the center coordinates of the position detection pattern arranged at the corner of the QR code.

  Subsequently, a coordinate list of position detection patterns is created (step S304), and three are selected from the list of position detection patterns (step S305). Then, it is determined whether or not there is a boundary line between the three selected position detection patterns (step S306). If there is a boundary line, the process returns to step S305 because it is not a position detection pattern within the same QR pattern. Select 3 of these.

  On the other hand, if there is no boundary line between the three selected position detection patterns, the position detection pattern is within the same QR code, and therefore the positional relationship between the three position detection patterns is a right isosceles triangle. (Step S307), and if it is not a right isosceles triangle, another three are selected (step S305). In the case of a right isosceles triangle, these three position detection patterns constitute a QR code (step S308), and the coordinates of the three position detection patterns are held and deleted from the list (step S309). .

  Next, it is determined whether or not three or more coordinates of the position detection pattern remain in the list (step S310). If they remain, the process returns to step S305. If not, the QR code is detected based on the three position detection patterns constituting the QR code (step S311), and the detected QR code is decoded (step S312). Here, the method described in JIS-X-0510 and p65-p66 is used to detect the QR code from the three position detection patterns, and the method described in JIS-X-0510 is used to decode the QR code. Is used.

  As described above, since there is a boundary line between two QR codes, the three position detection patterns constituting the same QR code can be reliably and quickly found, and the QR code is accurately detected and decoded. Can be performed.

  Next, a third embodiment will be described. The third embodiment is characterized in that when a plurality of QR codes are arranged, the module size is changed and rearranged so as to be easily detected. FIG. 6 is a schematic diagram illustrating an example in which a difference in module size is provided for a plurality of QR codes. That is, as shown in FIG. 6A, for example, when two QR codes are arranged as an original document, drawing data of these QR codes is acquired, and the module size is changed for the two QR codes in the drawing data. Then, new drawing data is generated. FIG. 6B shows an example in which the module size of the left QR code is reduced to a level that is difficult to visually discern, and the module size of the right QR code is increased to a level that is difficult to visually discriminate.

  Thus, by providing a difference between the module sizes of the two QR codes, when the QR code is decoded by reading the printed medium, the two QR codes are surely divided and read according to the difference in the module size. It becomes possible. In changing the module size, as shown in FIG. 6C, the area occupied by the QR code may be the same or may be changed to a different QR code. Even in this case, the internal information is the same. As a result, the two QR codes can be reliably divided without deteriorating the appearance of the print output.

  FIG. 7 is a flowchart illustrating a process for detecting a plurality of QR codes having different module sizes. This detection process is executed by an electronic device that reads an image of a QR code and decodes the image.

  First, the center coordinates of the QR code position detection pattern are detected (step S401). This detection method uses the method described in JIS-X-0510, p65-p66, which shows the detection method of the center coordinates of the position detection pattern arranged at the corner of the QR code.

  Subsequently, the number of pixels of the width and height of the position detection pattern is acquired (step S402), and the module size of the position detection pattern is obtained by (width + height) / (7 × 2) (step S403). Thereafter, the center coordinates of the position detection pattern and the module size thereof are listed as a set (step S404).

  Next, three are selected from the list of position detection patterns (step S405). Then, it is determined whether or not the module sizes of the three selected position detection patterns are equal (including substantially equal) (step S406). If they are not equal, it is determined that they are not position detection patterns within the same QR pattern. Returning to S405, another three are selected.

  On the other hand, if the module sizes of the three selected position detection patterns are equal, they are position detection patterns within the same QR code, and therefore the positional relationship between the three position detection patterns is a right-angled isosceles triangle. (Step S407), and if it is not a right isosceles triangle, another three are selected (step S405). In the case of a right isosceles triangle, these three position detection patterns form a QR code (step S408), and the coordinates of the three position detection patterns are held and deleted from the list (step S409). .

  Next, it is determined whether or not three or more coordinates of the position detection pattern remain in the list (step S410), and if left, the process returns to step S405. If not, the QR code is detected based on the three position detection patterns constituting the QR code (step S411), and the detected QR code is decoded (step S412). Here, the method described in JIS-X-0510 and p65-p66 is used to detect the QR code from the three position detection patterns, and the method described in JIS-X-0510 is used to decode the QR code. Is used.

  In this way, the difference in the module sizes of the two QR codes enables the three position detection patterns constituting the same QR code to be found reliably and in a short time, and the QR code is accurately detected and decoded. Can be performed.

  Next, a fourth embodiment will be described. The fourth embodiment is characterized in that when a plurality of QR codes are arranged, the positions are shifted and rearranged. FIG. 8 is a schematic diagram illustrating an example in which the positions of a plurality of QR codes are shifted in the vertical direction. That is, as shown in FIG. 8A, when, for example, two QR codes are arranged as the original document, drawing data of these QR codes is acquired, and at least one arrangement of the two QR codes in the drawing data is obtained. New drawing data is generated by shifting the position. FIG. 8B shows an example in which the right QR code is shifted in the vertical direction and rearranged with respect to the left QR code.

  In this way, by shifting the positions of the two QR codes, when the QR code is decoded by reading the printed medium, the two QR codes can be reliably divided and read according to the difference in position. Become. Note that the direction of shifting the position may be a horizontal direction other than the vertical direction, a rotation angle (minute angle), or an angle in units of 90 degrees.

  FIG. 9 is a flowchart for explaining a process for detecting a plurality of QR codes arranged at different positions. This detection process is executed by an electronic device that reads an image of a QR code and decodes the image.

  First, the center coordinates of the QR code position detection pattern are detected (step S501). This detection method uses the method described in JIS-X-0510, p65-p66, which shows the detection method of the center coordinates of the position detection pattern arranged at the corner of the QR code.

  Subsequently, a list of center coordinates of the position detection pattern is created (step S502), and three are selected from the list of position detection patterns (step S503). Then, it is determined whether or not the positional relationship of the three selected position detection patterns is horizontal or vertical (step S504). If not, the process returns to step S503 as not being the position detection pattern in the same QR pattern, and another Select 3 of these.

  On the other hand, when the positional relationship between the three selected position detection patterns is horizontal or vertical, the position detection pattern is within the same QR code, so the positional relationship between the three position detection patterns is two-dimensional. It is determined whether or not it is an equilateral triangle (step S505). If it is not a right isosceles triangle, another three are selected (step S503). In the case of a right isosceles triangle, these three position detection patterns form a QR code (step S506), and the coordinates of the three position detection patterns are held and deleted from the list (step S507). .

  Next, it is determined whether or not three or more coordinates of the position detection pattern remain in the list (step S508), and if left, the process returns to step S503. If not, the QR code is detected based on the three position detection patterns constituting the QR code (step S509), and the detected QR code is decoded (step S510). Here, the method described in JIS-X-0510 and p65-p66 is used to detect the QR code from the three position detection patterns, and the method described in JIS-X-0510 is used to decode the QR code. Is used.

  As described above, since the positions of the two QR codes are shifted, the three position detection patterns constituting the same QR code can be found reliably and in a short time, and the QR code is accurately detected and decoded. Can be done.

  Next, a fifth embodiment will be described. The fifth embodiment is characterized in that when a plurality of QR codes are arranged, they are rearranged in different colors. FIG. 10 is a schematic diagram illustrating an example in which a plurality of QR codes are rearranged so that colors are different. That is, as shown in FIG. 10A, when two QR codes of the same color, for example, are arranged as the original document, drawing data of these QR codes is acquired, and one of the two QR codes in the drawing data is obtained. New drawing data is generated so that one color is different from the other color. FIG. 10B shows an example in which the left QR code is black while the right QR code is a color other than black.

  In this way, by changing the colors of the two QR codes, when the QR code is decoded by reading the printed medium, the two QR codes can be reliably divided and read by the difference in color. Become.

  FIG. 11 is a flowchart illustrating a process for detecting a plurality of QR codes having different colors. This detection process is executed by an electronic device that reads an image of a QR code and decodes the image.

  First, the color of the QR code to be detected is designated (step S601), and the center coordinates of the QR code position detection pattern are detected from the read image (step S602). This detection method uses the method described in JIS-X-0510, p65-p66, which shows the detection method of the center coordinates of the position detection pattern arranged at the corner of the QR code.

  Subsequently, a coordinate list of position detection patterns is created (step S603), and position detection patterns other than the color designated in step S601 are deleted from the list (step S604).

  Next, three are selected from the list of position detection patterns (step S605). Then, it is determined whether or not the positional relationship of the selected three position detection patterns is a right isosceles triangle (step S606). If it is not a right isosceles triangle, another three is selected (step S605). . In the case of a right isosceles triangle, these three position detection patterns constitute a QR code (step S607), and the coordinates of the three position detection patterns are held and deleted from the list (step S608). .

  Next, it is determined whether or not three or more coordinates of the position detection pattern remain in the list (step S609). If left, the process returns to step S605. If not, the QR code is detected based on the three position detection patterns constituting the QR code (step S610), and the detected QR code is decoded (step S611). Here, the method described in JIS-X-0510 and p65-p66 is used to detect the QR code from the three position detection patterns, and the method described in JIS-X-0510 is used to decode the QR code. Is used.

  As described above, since the colors of the two QR codes are different, the three position detection patterns constituting the same QR code can be found reliably and in a short time, and the QR code is accurately detected and decoded. It becomes possible.

  Next, a sixth embodiment will be described. The sixth embodiment is characterized in that, when a plurality of QR codes are arranged, markers are rearranged with inconspicuous colors near each QR code. FIG. 12 is a schematic diagram for explaining an example of rearranging each of a plurality of QR codes with a marker. That is, as shown in FIG. 12A, for example, when two QR codes are arranged as an original document, drawing data of these QR codes is acquired, and yellow or the like is adjacent to the two QR codes in the drawing data. New drawing data to which a marker of a color that is difficult to be seen by a person is added. FIG. 12B shows an example in which a cross marker M is added near the upper left of each QR code.

  As described above, by providing the marker M in the vicinity of each QR code, when the QR code is decoded by reading the printed medium, the two QR codes are reliably divided and read by detecting the marker M. Is possible.

  FIG. 13 is a flowchart illustrating a process for detecting a plurality of QR codes with markers. This detection process is executed by an electronic device that reads an image of a QR code and decodes the image.

  First, the center coordinates of the QR code position detection pattern are detected (step S701). This detection method uses the method described in JIS-X-0510, p65-p66, which shows the detection method of the center coordinates of the position detection pattern arranged at the corner of the QR code.

  Subsequently, after creating a list of center coordinates of the position detection pattern (step S702), the marker is detected from the read image to detect the reference coordinates of the marker (step S703). As a marker detection method, a general pattern matching method may be used. After detecting the marker, a list of marker coordinates is created (step S704).

  Next, one marker coordinate is selected from the marker list (step S705), and three position detection patterns close to the marker coordinate are detected from the position detection pattern list (step S706). Then, it is determined whether or not the positional relationship of the detected three position detection patterns is a right isosceles triangle (step S707). If it is not a right isosceles triangle, another three are detected (step S706). . In the case of a right isosceles triangle, these three position detection patterns constitute a QR code (step S708), and the coordinates of the three position detection patterns are held and deleted from the list (step S709). . Further, the coordinates of the selected marker are deleted from the list (step S710).

  Next, it is determined whether or not three or more coordinates of the position detection pattern remain in the list (step S711), and if left, the process returns to step S705. If not, the QR code is detected based on the three position detection patterns constituting the QR code (step S712), and the detected QR code is decoded (step S713). Here, the method described in JIS-X-0510 and p65-p66 is used to detect the QR code from the three position detection patterns, and the method described in JIS-X-0510 is used to decode the QR code. Is used.

  In this way, since the markers are attached in the vicinity of each QR code, the three position detection patterns constituting the same QR code can be found reliably and in a short time, and the QR code can be detected accurately. Decoding can be performed.

  In the embodiment described above, the QR code is taken as an example of the two-dimensional code. However, the present invention is not limited to this, and various two-dimensional codes (for example, PDF417, Maxi Code, Data Matrix) Applicable to)). Further, the two-dimensional code generation program of the present invention can be stored and distributed in a predetermined storage medium, or distributed via a network.
