The present invention relates to code reading, and more particularly, to a method and apparatus for reading a code incorporating code information according to an image.

Recently, information management and information connection services using various types of one-dimensional and two-dimensional barcodes have been provided. In particular, the use of two-dimensional barcodes that are easier to recognize and accommodate a greater amount of information than one-dimensional barcodes has been expanded.

1 is a view showing the configuration of a two-dimensional bar code according to the prior art.

Referring to FIG. 1, a commonly used two-dimensional bar code 10 is composed of a finder pattern 12 and a data pattern 14. The data pattern 14 is embedded with code information, and the finder pattern 12 recognizes the data pattern 14 and recognizes the position and inclination of the two-dimensional barcode 10 by using the finder pattern 12. In addition, the width, height, and the like of the data pattern 14 can be recognized. In addition, one side of the finder pattern may include a parity pattern for determining whether the data pattern 14 is properly represented.

The code information can be read in the two-dimensional barcode 10 by the contrast difference of the data pattern 14 displayed in black and white. For example, the white portion of data pattern 14 may be read as "0" and the black portion as "1". That is, since each cell of the data pattern 14 according to the two-dimensional barcode 10 may have only two values, there is a limit to the variety of code information.

Accordingly, a method of increasing the variety of code information by using various colors such as red and blue in the data pattern 14 and using different values according to the colors is attempted. For example, red can be set to 00, blue to 01, yellow to 10, and green to 11 to represent four values in one cell.

However, the two-dimensional bar code 10 is excellent in terms of providing information, but the image shown to the user has a strong feeling of code, and thus the user familiarity is low. In recent years, design elements have been added to the code itself to improve visual user friendliness. However, there are limitations in providing various images with codes read by contrast and color discrimination.

Accordingly, an object of the present invention is to provide a code that can increase the amount of information that can be displayed, and a method and a device for reading the code thereof.

Another object of the present invention is to provide a code using an image of a circle, an ellipse, a polygon, and the like, and a method and apparatus for reading the code.

It is still another object of the present invention to provide a code, a method of reading a code, and a device for attaching a background image.

Other objects of the present invention will become more apparent through the preferred embodiments described below.

According to an aspect of the present invention for achieving the above object, an apparatus for reading a code formed to read a predetermined information, comprising: an imaging module for imaging the code; And a code information reading module for recognizing the code in an image captured by the imaging module and reading code information of the code, wherein the code includes at least one data image having a data value and the code information. The reading module is provided with a code reading device, which reads the code information by analyzing at least one of the area, shape, and color of each data image.

Here, the code information reading module analyzes any one of the area, shape, and color by using at least one of a comparison reference information cell of the code, a reference cell including a reference image, and a binding cell that performs a binding pattern function. It may be determined whether to read the code information.

The data image may be formed in at least one of a circle, an ellipse, and a polygon.

The code information reading module may read the code information by comparing the area of the reference image and the data image.

The code information reading module may read the code information by comparing at least one of the total area of the code and the area of the cell of the code with the area of the data image.

The memory device may further include a memory configured to store information necessary for the code information reading module to read code information of the code, wherein the memory includes an image table in which data values are set according to the shape of the data image. The information reading module may read the code information by comparing the shape of the image table with the analyzed data image.

In addition, the code information reading module may perform analysis of each data image in an order according to a preset direction.

According to another aspect of the present invention, there is provided a method of reading a code configured to read predetermined information in a code reading device, the method comprising: (a) recognizing the code through a binding pattern of the code; (b) analyzing at least one of an area, a shape, and a color of at least one data image having a data value of the code; And (c) reading code information using at least one of an area, a shape, and a color of the analyzed data image, and a recording medium having recorded thereon a program for executing the method.

The step (b) may include: determining a comparison criterion using at least one of a comparison reference information cell of the code, a reference cell including a reference image, and a finding cell that performs a binding pattern function; And determining which of the code information is read by analyzing the area, shape, and color according to the comparison criteria.

When analyzing the area of the data image, the code information may be read by comparing the area of the reference image of the code, the entire code, the cell of the code with the area of the data image.

In addition, when analyzing the shape of the data image, the code information may be read by comparing the shape of the data table and the analyzed data image with preset data values according to the shape of the data image.

The method may further include displaying the read code information.

The method may further include acquiring additional information corresponding to the code information through a network.

Hereinafter, a code incorporating code information according to an image according to an exemplary embodiment of the present invention, a method and a device for reading the code thereof will be described in detail with reference to the accompanying drawings.

2A to 2E are diagrams showing the configuration of a code according to preferred embodiments of the present invention.

Referring to FIG. 2A, a code according to the present invention includes a reference cell 210 in which a reference image (see FIG. 3) is displayed and one or more data cells 220 in which a data image is displayed.

The reference image of the reference cell 210 is a reference that is compared with each data image of the data cell 220, and the data according to the comparison of at least one of the shape, area, color, and combination thereof between the reference image and the data image. Information in cell 220 can be read. For example, when the area is compared, assuming that the area of the reference image is 1, and a data image of four levels (1/4 or less, 1/2 or less, 3/4 or less, 1 or less) is set. Assume that the code reading device (see Fig. 7) compares the area of the reference image with the area of the data image of each cell, and thus the four values of each cell (00, 01, 10, 11) by the difference in area. Is read).

The reference image and the data image (hereinafter collectively referred to as "cell image") can be differentiated from areas other than the cell image in the cell and contrast (or color) so that they can be recognized by the code reading apparatus. That is, the code reading apparatus may recognize the cell image by distinguishing between the contrast and the color in the cell.

In addition, the reference cell 210 may function as a finding pattern for recognizing the location of the code. In other words, the code reading device recognizes the code by the reference cell 210. The cell image will be described later with reference to related drawings.

Referring to FIG. 2B, the data cell 220 of the code may be divided into one or more information cells 222 and parity cells 224 representing code information. The information cell 222 is a cell in which code information of a code is set, and the parity cell 224 is for determining whether the information cells 222 are properly represented. The parity cell 224 vertical to the right side of the code may be referred to as a row parity cell, and the parity cell 224 horizontal to the bottom of the code may be referred to as a column parity cell. Since the use of the parity cell 224 will be apparent to those skilled in the art, a detailed description thereof will be omitted.

In another embodiment, the code according to FIG. 2C further includes a separate finding cell 230 that performs only a function of displaying a reference image and functions as a finding pattern. That is, the code reading device may recognize the position and inclination of the code by using the finding cell 230 and may also recognize the width, height, and the like of the data cell. This distinguishes the binding cell 230 from the reference cell 215 as compared to the code according to FIG. 2A, thereby further increasing the code recognition rate and the clarity of the reference image of the reference cell 215. Although the drawing cell 230 is shown as two in the figure, the finding cell 230 may be formed of one or more than two. That is, the code reading device may recognize the code through at least one or more of the finding cells 230.

In another embodiment, the code according to FIG. 2D is composed of a finding cell 230, a parity cell 240, and an information cell 250 without a reference cell. The method of reading the code according to FIG. 2D does not compare the reference image and the data image. When the comparison reference is wide, the size of the entire code or each cell size (ie, width) and the size of the data image are compared. That is, the code reading device recognizes the code through the finding cell 230, recognizes the entire code size, or divides the entire code size by the total number of cells, and recognizes the cell size. By comparing the magnitudes, each value of the data cell can be read. Here, the total number of cells of the code may be set and fixed in advance, and when it is used variably, it may be recognized through the finding cell 230 and / or the parity cell 240. For example, the number of cell images of the horizontally located pinning cell 230 and the parity cell 240 is counted, and the number of the cell images of the vertically located pinning cell 230 and parity cell 240 at the left side of the code. Count the total number of cells.

If the comparison criterion is a shape, the code does not include the reference image separately, and the data value may be preset according to the shape of the data image. Therefore, the code reading apparatus may read data values corresponding to the shapes of the data images by using the image table in which the shape-specific data values are set.

Here, the code according to an exemplary embodiment of the present invention may further include a comparison reference information cell indicating information on a separate comparison criterion (hereinafter, “comparison reference information”) so that the code reading apparatus can determine the comparison criterion. It may be. In another embodiment, the code does not include the comparison reference information cell separately, and if the reference cell is included in the code, the comparison criterion is determined as' area ', and if the reference cell is not included in the code, the comparison criterion is' You can also judge the shape. Alternatively, the reference image or the finding cell 230 of the reference cell may be set to have comparison reference information. For example, when the reference image is circular, the width may be set as a comparison criterion, and in the case of the quadrangle, the shape may be set as the comparison criterion. As another example, a comparison criterion may be set according to an image shape of the finding cell 230 by attaching a separate image to the finding cell 230. It goes without saying that all methods other than the setting of the comparison criterion information by which the code reading apparatus can determine the comparison criterion of the code can be equally applied.

In addition, in FIG. 2A to FIG. 2D, the code has 5 * 5 cells (25 cells) as an example, and codes having cells of other sizes (3 * 3 or more) may be equally applicable. In addition, although only a rectangular code is described as an example, it will be apparent that the same or similar shape may be formed by including each of the above-described components in a triangle, circle, oval, and other forms.

In another embodiment, the code according to FIG. 2E includes a finding area 260, a parity area 270, and an information area 280. The information area 280 is an area where data images having code information are located, and the parity area 270 is an area where data images having parity information are located. In the code according to the present embodiment, a data image may be freely positioned within a code without cell boundaries. That is, after detecting the recognition range of the code through the binding pattern (finding area 260), the freely arranged data image is read. Here, when the comparison criterion is wide, it is preferable to include the reference image. Of course, the overall size of the code and the size of the data image can be compared, but since it is difficult to obtain an absolute comparison value, the comparison with the reference image is more preferable.

The order of reading each data image of the code according to this embodiment may vary depending on the starting criteria. For example, when the order is set from the top to the bottom, the data images are read in order from the top end of the data image in high order. As another example, when the order is set from left to right, the data images are sequentially read in the order in which the leftmost cross section of the data image is on the left. In other words, the first detected data image is read first according to the reading direction.

Accordingly, when the code according to FIG. 2E is used, data images may be freely disposed in the code, and thus, it is easy to express various images that are backgrounds in the code and further increase user friendliness. An example of using the code according to the present embodiment will be described later with reference to the accompanying drawings.

3 illustrates reference image and data images of a code according to a preferred embodiment of the present invention.

Referring to FIG. 3, the cell image (reference image and data image) may be set as a model of a rectangle, a triangle, a circle, an ellipse, a star, and the like. Since the code information of the code is read by a comparison of at least one of the shape, area, color, and a combination of the reference image and the data image, the reference image and the data image are selected according to the comparison criteria. It may be formed to have one.

For example, when the comparison reference is an area, all models having a certain amount of area are applicable to the reference image and the data image. In the above-described example, various values of the data image may be applied. For example, when the comparison criterion is wide, the width ratio of the reference image and the data image may be set in various ways such as four or five levels, and accordingly, a value of the data image may be variously set.

As another example, when the comparison criterion is a shape, two values of the same case and a different case may be provided according to a comparison of the shape of the reference image and the shape of the data image. That is, when the shape of the data image and the shape of the reference image are the same, the value of the corresponding cell is read as 0. When the shape of the data image and the shape of the reference image are different, the value of the corresponding cell is read as 1.

As another example, a data value of a data image according to each shape may be preset in advance without comparison with a separate base image, so that the data value may be read according to the shape of the data image. As described above, a data value corresponding to each shape of the data image may be read using the image table in which the shape-specific data values are set.

Therefore, since the shape of the data image can be variously formed, it is easy to express various background images serving as a background in the code. For example, if you want to represent an elephant image as a background image in your code, a portion of the elephant image will be displayed in each cell, thus forming a data image of each data cell to be linked to the elephant image, making it more natural to the code itself. I can express an elephant image.

In addition, it is natural that the reference image and / or data image may be set by a comparison method based on at least one of shape, color, area, and a combination thereof.

Hereinafter, an embodiment according to a code and a process of reading a code according to each comparison criterion will be described with reference to the drawings.

4 through 6 are diagrams illustrating respective codes according to preferred embodiments of the present invention.

In the code 400 of FIG. 4, a value of a data image is set by comparing an area of a reference image and a data image. In addition, the code 400 according to FIG. 4 has a configuration of the code according to FIG. 2B and includes a reference cell 420, a parity cell 440, and an information cell 460. A circular reference image is displayed in the reference cell 420, and a data image having four size areas of the same various shapes is displayed in the information cell and the parity cell. It is apparent that four or more data images having different areas may be set depending on the method for specifying the size of the recordable data image.

Reference numeral 480 is a table showing data values of the information cell set by the area ratio of the reference image and the data image. Since the ratio may have some error, the ratio is set closer. For example, if the ratio is 4/9, it is read as "01" because it is closest to 1/2. Here, as described above, the area of the code itself or the area of each cell and the area of the data image may be compared without including the reference image. In this case, the reference cell performs only the function of the finding pattern.

It is also possible to further increase the data value by comparing the colors. For example, when the color of the reference image is a blue index, it may be set to 0 if the color of the data image is blue, and 1 if the color of the data image is blue. Therefore, the data image can be set to a total of eight data values by comparing areas and distinguishing colors.

Referring to FIG. 4, referring to a method of reading code information of a code, four information cells according to reference numeral 410 indicated by dotted lines among the information cells have values of 10, 11, 10, and 00 from the left, respectively. Thus, the information cells 410 can be read with a value of 10111000.

Here, although each data image is shown as being located at the center of the cell, it can be located anywhere in the cell. In addition, although the data images are formed only in the same shape (circular shape) in the drawings, it will be apparent that the shapes of the reference image and / or the data image may be formed differently from each other because the comparison is based on the area of the data image. .

According to another exemplary embodiment of the present invention, a code according to a case of setting a comparison reference between a reference image and a data image into a shape will be described with reference to FIG. 5.

Referring to FIG. 5, a data image table 550 in which data values are preset according to the shape of a data image is illustrated.

The code 500 according to the present embodiment may be formed of only data images without requiring a reference image. Of course, the code 500 may include a binding cell and a parity cell. Thus, data cells according to reference numeral 510 of code 500 are read with a data value of 1101010010.

Since the code 500 according to the present embodiment may use various data images in the code itself, it is easy to display a background image.

In the code according to FIGS. 4 and 5, a data image is formed in each data cell to have a data value. However, a specific data value (for example, 00) may be set in a cell without the data image. have. Therefore, four data values can be set in three types of data images (width and shape).

According to FIG. 6 it is shown that a data image is formed in the code of the format according to FIG. 2E. The data value of the data image can be read according to the comparison of the width with the reference image, and each data image can be read from top to bottom. Therefore, each data image can be read out in the order of the numbers as shown in the figure. As shown in the lower part of the figure, each data image is read out with each data value so as to correspond to the area of the area in the order by a predetermined rule. Here, low parity 3 is used as a parity value for the data image according to the order 1, 2, low parity 8 according to the order, 4, 5, 6, 7, low parity 11 for the data image according to 9, 10 Can be used as a parity value.

Column parity 11 is used as a parity value for data images according to 1 and 5, and column parity 11 is used as an order of reading a data image from left to right in the same manner. As a parity value for the data image according to 10, 7, 4, and 12, the column parity 15 may be used as a parity value for the data image according to 6, 2, 13, and 9.

Therefore, each data image of the information area and the parity area in the code can be freely formed without cell division, so that the effect of easily setting the code in harmony with the background image can be obtained.

Hereinafter, an example in which the code 400 according to FIG. 4 is applied to an arbitrary background image will be described with reference to FIG. 7.

7 is a diagram illustrating a code displaying a background image according to an exemplary embodiment of the present invention.

The code 700 according to FIG. 7 is formed on a background image 710 serving as a background. Although each cell image (reference image and data image) of the code 700 is shown as having a circular border only in the drawing, it may be formed in a color similar to the background image 710 in a range that can be recognized by the code reading apparatus. Can be. Therefore, the background image 710 may not be greatly deteriorated by the naked eye by the cell image of the code 700, and thus the user may feel the intimacy and specific information ("advertisement" through the background image) through the background image 710. Information).

Here, it is obvious that the outer dotted line of the code 700 as shown in the figure may be removed to increase the clarity of the background image 710.

8 is a functional block diagram showing the configuration according to the function of the code reading apparatus for reading the code information of the code according to an embodiment of the present invention, Figure 9 is a code reading apparatus according to an embodiment of the present invention This is a flowchart showing a process of reading a code.

Referring to FIG. 8, the code reading device 50 reads out an imaging module 51 for imaging a code, a code information reading module 53 for recognizing the picked-up code, and reading code information. And a memory 55 for storing necessary information.

The imaging module 51 uses an image corresponding to the code by using light inputted by external light (or light emitted from an internal light emitting module (not shown)) reflected on the code (or an object to which the code is printed or attached). Create

The code information reading module 53 reads code information of the code through the image generated by the imaging module 51. That is, the code information reading module 53 reads code information by analyzing and comparing at least one of a reference image of the code, a model, an area, and a color of the data image to recognize a data value of the corresponding data image. Here, the comparison criteria may be set in advance, or as described above, the comparison criteria may be determined using at least one of a comparison reference information cell, a reference cell, and a finding cell. Alternatively, the comparison method may be determined according to whether the shape of the base image and the data image are the same, whether the areas are the same, whether the colors are the same. For example, when the base image and the data image have the same shape and there is a data image having a different area from the base image, it may be determined by a comparison method according to the area. As another example, if there is a data image having a different area and shape from the base image and the area is different, it is determined by a comparison method combining the area and the shape. In addition to the above examples, corresponding comparison methods may be determined according to the base image and the data image.

Accordingly, the code information reading module 53 recognizes at least one of the area, shape, and color of the reference image and the data image, and compares each other to read data values of the data image according to a comparison method. do. As described above, when the reference image does not exist, the entire code area or the area of the cell may be compared with the area of the data image. In addition, when the comparison reference is a shape, the data value of the data image is read using a previously stored image table (a table including data values set according to the shape of each data image). Here, since the shape of the data image and its set data value may be changed, the image table may receive information about the changed contents from time to time or at a specific time from a predetermined server. Therefore, a communication module (not shown) for communication through the communication network with the specific server described above may be further included. Of course, it can be upgraded by wire from a device such as a PC without receiving through a communication network. In addition, the code reading device 50 may obtain additional search information corresponding to the code information read using the communication module from the search information providing server (not shown) coupled through the communication network. In addition, when the code information is connection information of a specific server such as URL, it may be connected to the corresponding server using a communication module.

The memory 55 performs a function of storing information necessary for the imaging module 51 and the code information reading module 53 to perform a function of imaging a code and reading code information. It also performs a function of temporarily storing an image of the captured code. In particular, the memory 55 includes a table as shown by reference numeral 480 of FIG. 4 (data values according to the ratio) so that the code information reading module 53 can read the data value according to the comparison between the reference image and the data image. The set table) and / or the above-described image table. In addition, even when the code information reading module 53 analyzes the area of the cell image, the memory 55 stores information about the shape of the cell image so that the cell images of various shapes can be easily recognized.

Here, the code reading device 50 may be a mobile terminal such as a mobile phone, a PCS, or a PDA equipped with a camera module. That is, the camera module of the mobile terminal performs the same function as the imaging module 51, and the code information reading module 53 and the memory 55 may be provided inside the mobile terminal. Therefore, the mobile terminal capable of performing the code reading function can obtain additional information corresponding to the code information through the network by using the code information read by reading the code according to the present invention.

For example, when the code information is a URL of a specific server, the mobile terminal reading the code connects to a web server corresponding to the URL. As another example, when the read code information is movie title information “Well Come to Dongmakgol”, the mobile terminal may be provided with search information corresponding to the movie through a specific server.

In summary, the mobile terminal, which is one of the code reading devices 50, may read a code according to the present invention and perform various functions such as searching, connecting to a web server, and outputting the read information using the read code information.

Hereinafter, as a code reading apparatus 50, a process of reading code information of a code including a reference image by using a mobile terminal as an example will be described.

Referring to FIG. 9, in step 910, the mobile terminal recognizes the existence and location of a code through a finding cell of the code. Here, it will be apparent from the foregoing that the reference cell may perform the function of the finding cell.

In step 920, a comparison criterion is determined. As described above, the method of determining the comparison criterion may be determined from at least one of a comparison reference information cell, a reference cell, and a finding cell, and may also be determined by comparing areas, colors, and models of the reference image and the data image. It may be. For example, a comparison criterion may be determined by analyzing and comparing a model, an area, and a color of a reference image and at least one data image (two or more are preferable for accuracy of judgment). In this case, when the comparison criterion is preset as one, it is natural that step 820 may be omitted.

In operation 930, the data image of the data image is read by comparing the reference image with the data image of each data cell so as to correspond to the comparison criteria. Of course, the step of analyzing at least one of a model, an area, a color, and a combination of the reference image and the data image according to the comparison criteria is preceded, and the data value of the data image is read out according to the comparison of the analyzed values. Analysis directions for reading data values of each data image may vary in a horizontal forward / reverse direction, a vertical forward / reverse direction, a zigzag forward / reverse direction, and the like.

In operation 940, an error of the data value of the information cell is determined using the data value of the parity cell among the data cells (including the information cell and the parity cell).

If there is no error in step 950, the data value of the read information cell is processed according to a preset method. For example, in case of general information, the display information is displayed through a display module (not shown), or in case of UAL, the web server is connected. In addition, the read code information may be transmitted to the search information providing server through a communication network to receive and output additional search information corresponding to the code information from the search information providing server.

If an error is detected as a result of the determination in step 940, an error message is displayed through the display module in step 855.

It will be apparent from the foregoing descriptions that a process of reading a code not including the reference image other than the code including the above-described reference image may proceed similarly.

The method of the present invention as described above may be implemented in a program and stored in a computer-readable recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.).
