Jing technology

Two-dimensional code, can encode a plurality of types of characters, and a this having an error correction function has been utilized in the fields such as distribution and product management, two-dimensional code in various forms have been developed .

Conventional two-dimensional code, Tsuteori Todoma for use in applications to replace the one-dimensional barcode one de, as information Therefore, associated with for example the management code and this, the request specification of the small capacity It was sufficient if you can store the information. In recent years, to support the independence of the various disabilities, it is high or one opportunity to actively promote the social participation. Among such movement, the inventors have, In developing sentence reading-up system for the audio-visual disability were investigated the use of two-dimensional code. As a specification of the utility aspect Karaso, 1 page text information, specifically, can be stored in 8 0 0 of about characters for example 2 cm 2 symbols in Japanese, and printed in evening commercial laser purine can it has been requested.

However, when you'll realize the above requirement specifications in the conventional two-dimensional code is not sufficient reading rate is obtained if printed with the desired density, this one, the size when printing at a density readable becomes too large, that Problem has occurred.

As the cause of such a problem, in part, to a conventional two-dimensional code is not designed to store large amounts of information described above, over the print area data cell other than increasing the capacity to the head resulting in larger summer, and the like may be referred to. Further, the read rate problem is that the accuracy of positioning can not be sufficiently ensured when sampling the data cell. Conventionally, as a method of indicating the print pitch data cells, it was also tried to arrange the light-dark pattern of the same size as the data cells are alternately every cell. However, in this method, current high density printing result in laser purine evening, or the toner particles Hisan', blurred like, it is difficult to improve the accuracy by the printer-specific characteristics. The other hand, lever can be run with sufficient accuracy positioning, the reading of Isseki de, even if there is some toner scattering and blur in printing, by the image processing or error one correction code processing, can be sufficiently complexed There was found.

Further, conventionally, as the symbol information device, for example as described in JP-A-7- 2 1 4 9 3 9 JP, allowed to record the pre-stored information to the host device, recording a one-dimensional bar first cord made to have the role of calling function, the storage information and system for output by voice, as described in JP-a 7-1 8 2 3 7 9 discloses the data read from the barcode one de the voice to send Te mobile terminal device has been known.

Further, as described in JP-A 7-1 7 5 8 8 3 JP, is read by the matrix equation two-dimensional code, the apparatus and method for converting a data symbol in the text document data has been known . However, in a single apparatus main body, and decoding by reading a dot matrix type two-dimensional code, together with the to the audio output from the internal speaker via the speech synthesis by rule processing unit, to output together data for braille purine evening until ivy or a can.

Conventionally, as a two-dimensional code voice apparatus and two-dimensional code voice method, and printing and two-dimensional code of a text document, the output from the voice synthesizing apparatus decodes the two-dimensional co-once symbols by the reading equipment how to have been tried many. Also, it has been issued to many market-to-speech software text documents, in these software, the first to set the sound quality element of the entire document, at a constant sound quality elements from the first text document until the last It had been voiced.

Therefore, even if a conventional two-dimensional code voice apparatus and two-dimensional code voice methods odor, it is difficult to contain a plurality of sound elements in one of the text document, a single sound elements set pre Me It had been voiced by.

However, the entire text document is vocalized by a single sound elements, is very monotonous, there is a problem that bored a listener. In particular, in the case of multiple sentences of a document has been described as a premise the presence of a plurality of different speakers, status quo to-speech in the same sound quality elements such text document from beginning to end, not there is a problem of poor is a natural change.

In addition, conventional, computer Braille transcription is carried out with reference to a reluctant Japanese analysis process the dictionary for the kanji and kana sentence, was to output the braille data.

In the other hand, as a text speech synthesizer, for example, as described in JP-A 1 1 3 3 8 6 7 3 JP, have rows Japanese analysis processing on kanji and kana, speech synthesis parameters It had outputs speech synthesis to convert the intermediate language added with Isseki. That is, the conventional text-to-speech synthesizer, the intermediate language has been used only for voice de Isseki output.

However, if one sentence Braille and a selectively should also this is if is output by voice, the Braille text - converts Braille conversion, this one, for the speech text - to convert speech conversion synthesizing that, there was a need to use a method of two ways. For this reason, it is necessary to Japanese analysis of two times, efficiency is poor. Disclosure of the Invention

Hereinafter, will be described with reference to the drawings some embodiments of the present invention. (1) First Embodiment of the two-dimensional co one de

Figure 1, as shown in c figure is a schematic diagram showing a first embodiment of a two-dimensional co-one de according to the present invention, the two-dimensional code 1 of the present embodiment, binarized data is dark the matrix data unit 2 stored in the cell in the form of a square, and arranged square to surround the matrix data evening portion 2, by a solid line and it it vertically extending from each side Al~d 1 of this quadrangle heading line (protrusion) R 11~: R 14, R91~R 93, R31~R33, R51 ~ R53, and a R71~R73. Rectangles and heading line R. 11 to: R93 is a pattern in the present embodiment, thereby, the data density information and positioning information is provided by using a reading method which will be described later. Four square and width of each heading line is the same as the length of one side of the data cell.

Heading line R 11, R 12 is arranged to extend it which edges b 1, a 1 from point D. The heading line R 13 is placed from the point B to extend the sides d 1, further heading line R 14 is located from the point C to extend the edges c 1. These headings lines Rl 1 ~ R14 correspond to projections of the fifth to eighth in which it present embodiment. Of each corner A~D square, only 1 Chikarasho of point A (you corresponding to a fourth end point), is not provided heading line. Thus, as will be described later, the point A can be utilized as the origin of the two-dimensional code in the image processing for specifying the position coordinates of each cell.

Heading line R 91~R93, R31~R33, R51 ~ R 53, R71~R73 refers to it row or column direction of the position of its particular de Isseki cell. Heading line R 91~R 93, R 51~R 53, it it a square of sides a 1, c 1 are arranged at a pitch P 1 of predetermined length, and a first protrusion in which it present embodiment corresponding to the third collision force thereof. The heading line R 31~R33, R71~R73 is first that it rectangle sides bl, are arranged at a pitch P 2 of a certain length d 1, and the second protrusion in which it exemplary type condition equivalent to 4 of the projection. Pitch P l, it its Re length of P 2 is a known constant, the same value in the present embodiment.

Heading line R 91~: R 93, R 31~R 33 is disposed therefrom it sides a 1, b 1 two to extend outward of the four square. The other hand, heading line R51~R5 3, R71~R73 is arranged to extend inwardly facing square from two sides c 1, d 1 to other adjacent. Although all in the present embodiment the length of each heading line is the same, heading line R 51~R 53, R71 ~ R73 of inward a matrix de - as not to overlap the evening portion 2, the side c 1, dl It is spaced apart from the peripheral edge of the matrix data section 2. The number of headlines lines, horizontal direction by the number of data matrix de Isseki unit can be increased or decreased independently in each direction in the vertical direction. Therefore, it is possible to construct a two-dimensional code of various sizes and shapes depending upon the application site, such as the capacity of the data or printing. Thus, in the two-dimensional code 1 of the present embodiment, since there is no special printing pattern for such cut and positioned within the matrix de Isseki part 2, more and more minute small area of ​​its de it can be mounted Isseki. Furthermore, to increase the data capacity, it is possible to perform positioning and cutting out a single pattern surrounding the matrix data section 2, the area occupied by the entire two-dimensional code is proportional to the de Isseki capacity increase much smaller than the size. As a result, the two-dimensional code to store a high density a large amount of information is provided.

(2) the first embodiment of the method for reading two-dimensional code

Next, it described as a first embodiment of the two-dimensional code reading method according to the present invention how to read the two-dimensional code shown in FIG. Here, only the steps reading specific to the two-dimensional co-one de, description of the detailed procedures and adjustments to be on generally required reading process will be omitted.

Figure 2 is an explanatory view of a reading method of this embodiment, also, FIG. 3 is a flowchart showing a schematic procedure of shows to reading method in Fig.

1) First, capturing digital image data of the 2D code 1 using the imaging element such as a CCD (Step S 1).

2) Next, examine the distribution of the dark cell exists aspect of the image data (histogram), as shown in FIG. 2, to define a rectangular area AR 1 surrounding the two-dimensional code 1

(Step S 2).

3) Next, find a point in contact with each side of the peripheral edge of the rectangular area AR 1 (Step S 3). In the case of FIG. 2, the point A, E, F, H is obtained.

4) Subsequently, these points A, E, F, examines the segment on Dots connecting to each other adjacent points of H, correspond to any segment of a dark solid line rectangle sides Al~d 1 or a to determine constant (step S 4). The case shown in FIG. 2, line AE and the segment AF each four rectangular sides dl, may correspond to the solid line c 1 is determined. The other hand, there is no solid line corresponding to the line segment EH and the line segment FH. The intersection A between the line segment AE and the segment AF is selected as the origin of the secondary source code 1 (step S 5).

5) Next, examine the segments are substantially identical parallel to and length and the line segment AF from point A toward the point E, to identify a line segment BH identifying the points B and H from the end point . Similarly, examined segment CG is substantially identical parallel to the line segment AE and length toward the point A to the point F, will now determine the points C and G, further line BH and the line segment CG identifying an intersection D with (step S 6).

6) Then, to set virtual dashed (heading dashed line) is identical and the length parallel to the line segment AF, scan starting from the point A toward the point E bd 1, bd 2 ... a Ri, slide into exploring the heading line R 31 R73, R32 and R72, R33 and R71 (step S 7). Procedure At this time, since the distance from Heading dashed bd 1 ​​connecting the heading line R 31 and R73 to the point A, the length and pitch of each heading line is a known constant size of a data cell as a unit, as described above in location and length of each heading line it can be predicted on the basis of already positional relationship between the points a ~ D identified. Similarly, to set a virtual dashed line is identical and the length parallel to the line segment AE, ac starting from the point A toward the point F l, by scanning ac 2 ... and a heading line R93 R53, searching for a R 9 2 and R52, R91 and R51 (step S 7). Here, extending perpendicular line from AC (4 square edges c 1) the number of which extend perpendicularly inwardly from the recognized heading line and the line segment BD (4 square sides a 1) to the outside the number of ones and the same of the number of recognized the saw out and line, Similarly, the line segment AB (4 square sides dl) which extend perpendicularly inwardly from the recognized heading line and if the number of line segments CD (4 square sides bl) or al recognized heading line perpendicular to and extending outwardly identical, it can be confirmed that the normal search of each saw out lines were made. Further, as described above, the number of heading lines horizontal direction according to the number of data matrix de Isseki unit 2, since it is determined independently in each direction in the vertical direction, is recognized by the line segments (sides) depending on the number of headline line, to determine the capacity of the matrix data.

7) Then, as shown in broken lines in FIG. 2, a line segment bd l~bd 3 constituting the lattice shape by connecting together a point on the line of the recognized heading line at two sides it to its parallel quadrangle sequentially , assuming the ac l~ac 3 again, the intersection n 11~ of these line segments! It calculates coordinates of the iota 33 (Step S 8). These coordinates correspond to those extracted coordinates de Isseki cells in the matrix data section 2 at regular intervals.

8) Further, from the intersection coordinates obtained in the above 7), we obtain the coordinate values ​​of each cell by the cell number between known headings line, a data bit string by sampling the value of the binary of each cell (step S 9).

9) Finally, since the bit string data of the two-dimensional code 1 is pre error correction code adding performs error correction by using this. Thus, the original de Isseki is restored (step S 10).

Thus, according to the method of reading two-dimensional code of the present embodiment, by a simple image processing, together with the Isseki de stored in a matrix de Isseki unit 2 can be restored with high precision, the volume of data quickly it is possible to get to.

(3) Second Embodiment of the two-dimensional code

Figure 4 is a schematic diagram showing a second embodiment of a two-dimensional co-one de according to the present invention. As shown in the figure, two-dimensional code 3 of this embodiment includes a matrix de Isseki unit 2 which is stored in the binarized data is a cell of light and dark squares form, so as to surround the matrix data section 2 line LN 11~LS 14 that arranged (first line), LS 31 ~: LS34 (third segment), LS51~: LS54 (fifth line segment), LS71~LS 74 (7 and a line segment), heading line and extending from a substantially central portion that it perpendicularly of these line segments R 21~R24 (second line), R41 to R44 (fourth line), R 61 ~R64 (sixth line segment) comprises R81~R84 the (eighth line segment), and a graphic LC L-shaped with both ends continuous to the end portion of the LS5 4 and LS 74.

Matrix de Isseki unit 1 is composed of it it three in both X-direction and the y direction (L = M = 3) 9 subregions ordered adjacent (see FIG. 5). The small region, it it the N in both X-direction and the y-direction (N is a natural number) constructed are arranged next to each other are data cells. In the present embodiment, the number of the small region is the same in both X-direction and the y direction, the number of the small region is not limited to this, and can be changed independently of each other in the X direction and the y-direction.

Above line constitutes the first figure in this embodiment, also, the graphic LC constitutes a second graphic in the present embodiment. These rotation angle of a matrix de Isseki unit data density information (print pitch) is provided with a reading how to be described later. The width of each segment is the same as the length of one side of the data cell and the length of each line segment is determined the length of one side of the data cell as a basic unit.

Line LS 11 ~ LS 14, it is then placed in along the side a 2 square to form a peripheral edge of the matrix de Isseki unit 2 pitch to match the size of the small region. Similarly, the line segments LS 31 ~ LS 34, it is then placed in a pin Uz blood along the sides b 2 to match the size of the small region. The other hand, the line segment LS. 51 to: LS 54, it is then placed at a pitch along a line parallel to the side c 2 are spaced sides c 2 to match the size of the small region. Similarly, it is it arranged in line LS71~ 374 also matches the spaced apart from the side (line parallel to the 12 in the sides (12 Saizu Yan connexion the small area pitch.

Heading line R 21~R24 refers to it row or column direction of the position of its particular de Isseki cell. Heading line R 21~R 24, it is then arranged to extend from the line segment LS 11~LS 14 outside facing Matrigel box data unit 2. Similarly, Heading line R41~R44, it is it arranged to extend from the line segment Ls31 ~ LS 34 outside side facing the matrix data section 2. The other hand, heading line R61~! 6 4 is placed it thereto to extend toward the line segment S51~LS54 to the matrix de Isseki unit 2. Similarly, the heading line R 81~R84, it is it positioned so as to extend toward the line segment LS71~LS 74 to the matrix de Isseki unit 2. Although all in the present embodiment the length of each heading line are the same, inward heading line R61~: R64, as R 81 ~ R 84 does not overlap the matrix data section 2, the line segment S 51~LS 54, the line segment L S71~LS74 is spaced apart from the peripheral edge of the matrix data section 2.

The number of headlines lines horizontal direction according to the number and arrangement of the small areas included in the matrix de Isseki unit 2, can be increased or decreased independently in each direction in the vertical direction. Therefore, it is possible to construct a two-dimensional code of various sizes and shapes depending on the application location such that the capacity or printing Isseki de.

L-shapes LC of, because it has a perpendicular portion that is continuous with the ends of the line segment LS 54 and the line segment LS 74, in the image processing at the time of reading, which will be described later, a rectangular area AR for by Uni cutout in contact with the corner A by setting 3, it is possible to obtain the rotation angle of the data cells, also corner a is utilized, as described below, as the origin of the two-dimensional code 3 to locate coordinates of each cell can do.

Thus, in the two-dimensional code 3 of the present embodiment, since a special printing pattern for such cut and positioned within the matrix de Isseki unit 2 is not present, more and more minute small area of ​​its data it can be mounted. Also, by increasing large data capacity, since only the first and second graphic surrounding the matrix data portion 2 can be positioned and cut, the area occupied by the entire two-dimensional code, the increase in data capacity much less than proportional to size. Thus, to print a laser purine evening generic, two-dimensional code to store a high density a large amount of information is provided ο

(4) Second Embodiment of the method for reading two-dimensional code

Next, described as a second embodiment of the two-dimensional code reading method according to the present invention for two-dimensional co-one de read method shown in FIG. Here, the two-dimensional co-one de according to the present invention show only specific reading procedure, description of the detailed procedures and adjustments to be on generally required reading process will be omitted.

Figure 5 is an explanatory view of a reading method of this embodiment, and FIG. 6 is a flowchart showing a schematic procedure of shows to reading method in Fig.

1) First, capturing digital image data of the two-dimensional code 3 by using an imaging element such as a CCD (step S 11).

2) Next, examine the distribution (histogram) of 喑 cells aspect of the image data exists, as shown in FIG. 5, to define a rectangular area AR 3 surrounding the two-dimensional code 3

(Step S 12).

3) Next, find a point in contact with each side of the peripheral edge of the rectangular area AR 3 (step S 13). In the case of FIG. 2, the point A, E, F, H is obtained.

4) Then, determine these points A, examined E, F, a straight line of dots connecting with each other adjacent points to each other H, is where the point that are configured corner dark line (step S 14). The case shown in FIG. 5, it can be seen that there is such a line segment intersection and its vicinity of the straight line AE and the straight line AF. This one, in a straight line EH and the straight line FH no dark portion constituting a corner. The intersection A between the straight line AE and the straight line AF is selected as the origin of the two-dimensional code 3 (step S 15). Thus, it is possible to obtain the rotation angle of each data cell by determining the angle S between the sides of the straight line AE and the rectangular Aria AR 3.

5) Next, examine the line segment LS 54 and the length of the parallel and linear AF and linear AF is substantially the same from the point A toward the point E, the end points to identify the line segment LS 14 identify the pressurized et point B, more particularly the point H on the extension of the line segment LS 14. Similarly, line segments LS 61 and the line segment L segments LS 74 and the line segment LS 71 and the length of the parallel and straight AE and the straight line AE toward the point A to the point F is it that substantially the same S31 examined, now seek the points C and G, further identifies the intersection D between the straight line BH and the straight line CG (step S 16).

6) Then, to set virtual dashed (heading dashed line) is identical and the length parallel to the line segment AF, scan starting from the point A toward the point E bd 1, bd 2 ... a Ri, heading line R44 and R84, R43 and R83, slide into exploring R 42 and R 82 (step S 17). At this time, since the distance from Heading dashed bd 1 ​​connecting the heading line R 44 and R 84 to the point A, the length and pitch of each heading line is a known constant size of a data cell as a unit, the above-described position of each heading line can be predicted on the basis of already positional relationship between the points A~D identified in step. Similarly, to set a virtual dashed line is identical and the length parallel to the line segment AE, ac starting from the point A toward the point F l, by scanning ac 2 ... and a heading line R24 R64, R23 and R 63, searches the R22 and R62 (step S 17). The number of this case, as the recognized heading line extending perpendicularly towards the line AC to the matrix de Isseki 2
