Description

QR code that can be produced in various designs {QR CODE THAT CAN BE PRODUCED IN VARIOUS DESIGNS}

The present invention relates to a QR code that can be manufactured in various designs that can be combined with designs of various shapes to increase aesthetics and advertising effectiveness.

QR CODE is a two-dimensional barcode that overcomes the capacity limitations of the previously widely used one-dimensional barcode and expands its format and content, and can store character data in addition to numbers by containing vertical and horizontal information. These QR CODEs are usually read and utilized with a digital camera, dedicated scanner, or smartphone.

Initially, QR CODE was widely used for product management, such as automobile parts production management, and was later printed on various print media, etc. as an advertising tool that allowed users to search for product information, Internet information, etc. through QR CODE. developed into

For example, if a QR CODE is printed and inserted into a magazine advertisement, and people who see it recognize it by taking a photo of the QR CODE using their smartphone, etc., the web stored in the QR CODE It is being developed as an advertising tool by linking to sites and providing more detailed information. For this purpose, most smartphones support an application that allows you to capture and recognize the QR code.

Figure 1 is a diagram showing a conventional QR code.

Referring to Figure 1, the conventional QR CODE has a square shape. QR CODE consists of three location detection patterns 10 and data patterns 130 and 20 arranged between the location detection patterns 10.

The location detection pattern 10 defines the size, direction, or rotation angle of the QR CODE. For example, in the QR CODE of FIG. 1, two position detection patterns 10 are arranged at the top and one position detection pattern 10 is arranged at the bottom. Accordingly, even if the user photographs the QR Code from various angles, the part where the two position detection patterns 10 are arranged is recognized as the upper part of the QR Code.

The data pattern 130 (20) includes a plurality of black data cells 21 and white data cells 22. Each of the black data cells 21 and white data cells 22 has a rectangular shape, and predetermined information data is recorded and stored in each cell.

The conventional QR CODE described above increases the capacity of data that can be stored compared to the existing barcode, and thus companies, etc. use the QR CODE to provide various information to a large number of people, such as corporate products. Advertising information, etc. will be provided. However, the conventional QR CODE is composed of multiple data cells 21 and 22 arranged in a two-dimensional barcode form, so it is difficult to recognize or predict the information contained in the QR CODE from human perspective. It was impossible to do.

In other words, the conventional QR CODE cannot predict what information it contains by itself. Therefore, people must perform the process of recognizing the QR Code by taking a photo of it using a device such as a smartphone. This causes the QR Code recognition process to be cumbersome and inconvenient. The effectiveness of advertising using QR CODE decreased.

Therefore, the conventional QR CODE was proposed to be a QR code combined with an image to give an aesthetic feeling, but since most of the QR codes are formed in a square shape by the multiple position detection patterns 10 placed at the corners, the QR code is This was done by inserting an image into the space secured within.

However, the QR code with the image inserted like this was implemented only in a monotonous rectangular shape, making it difficult to combine with more diverse designs. In other words, the conventional QR code with an image inserted had a clear limitation in its effectiveness due to disadvantages due to the unique shape of the QR code.

The present invention was created to solve the above-described conventional problems. The purpose of the present invention is to provide a QR code that can be combined with various types of images to enhance aesthetics.

The present invention may include the following examples to achieve the above object.

An embodiment of the present invention includes a data pattern including a plurality of data cells in which a plurality of codes based on externally provided information data are recorded, a reference pattern indicating the extraction start point of the data cell, and a closed curve shape extending to determine the location of the data pattern. It provides QR code that can be produced in various designs including a code frame that specifies.

The present invention aligns the data cells and their extraction starting points in an irregular linear manner through a frame and arranges them according to the external shape of the inserted image, allowing designs and combinations of various shapes to be used for individuals, companies, or their products. Advertising effectiveness can be improved.

In this specification and claims, terms including ordinal numbers such as 'first', 'second', etc. may be used to distinguish between components. These ordinal numbers are used to distinguish identical or similar components from each other, and the meaning of the term should not be interpreted limitedly due to the use of these ordinal numbers. For example, components combined with these ordinal numbers should not be interpreted as having a limited order of use or arrangement based on the number. If necessary, each ordinal number may be used interchangeably.

In addition, the closed curve described in the specification of the present invention means that one line is connected and extended and interconnected to demarcate a specific area, and does not define a specific shape. In addition, the outlines on both sides of the code frame 110 are the same closed curve and are interconnected, but are defined as lines located in different directions from the viewpoint of the data cell or data pattern 130.

Hereinafter, preferred embodiments of QR codes that can be manufactured in various designs according to the present invention will be described in detail with reference to the attached drawings.

2 to 4 are diagrams showing one embodiment of the present invention. Among them, Figure 2 is a diagram showing the QR code by the code frame 110 having a circular closed curve shape, Figure 3 shows the inverted shape of the QR code of Figure 2, and Figure 3 is a closed curve in a bent form. This is a diagram showing the QR code using a code frame 110 composed of.

Referring to Figures 2 to 4, the present invention includes a code frame 110 in the form of a closed curve, a data pattern 130, and a reference pattern 120 indicating a start point of data recognition.

The code frame 110 can configure a layout such as the shape or size of the QR code 100. Specifically, the code frame 110 is a closed curve, and the location of the data pattern can be specified by dividing the area inside which the data pattern 130 is formed.

More specifically, the process of specifying the location of a data pattern involves detecting the outline of each data cell existing inside after detecting a code frame, and calculating the center point of each outline to obtain the position of each data cell. .

The code frame 110 may be formed to follow the shape of the image area 140 or an image inserted into the image area 140 by extending and changing the direction of the image area 140 along the outline. That is, the code frame 110 may have the shape of a closed curve that can be extended according to the shape of the image area 140, as shown in FIG. 2.

Alternatively, the code frame 110 may be configured with the inverted colors of FIG. 2 as shown in FIG. 3. That is, the code frame 110 may be expressed as a second color on a background of the first color, or may be expressed as a first color on a background of the second color.

Additionally, the code frame 110 can be implemented as a closed curve extending in the shape of an inverted 'L' shape, as shown in FIG. 4. At this time, the image area 140 may be formed inside the code frame 110 that is bent in an 'L' shape.

In summary, the code frame 110 according to the present invention specifies the position of the data pattern 130 and is extended in the shape of a closed curve to facilitate its detection and is inserted into the image area 140 or the image area 140. It can be defined as a closed curve that can be extended to bend according to the shape of the image or desired design.

The reference pattern 120 indicates a starting point from which data can be extracted from the data pattern 130. For example, a scanning terminal (not shown) photographs a QR code to which the present invention is applied, and sequentially extracts the value of the data pattern 130 in the direction set from the reference pattern 120 from the photographed image.

Here, the reference pattern 120 may be displayed directly in a demarcated area in the code frame 110 or in the code frame 110. At this time, the shape and color of the reference pattern 120 can be selectively applied among shapes, symbols, and images.

In addition, the reference pattern 120 can be manufactured in a shape and numerical range that have a different discriminability from the shape or numerical value of the data cell, preferably in a shape or numerical range (depending on the type of data cell or the starting point of data detection). For example, the length and thickness of the outline) can be set.

To explain more specifically, in addition to indicating the starting point, the standard pattern includes the format (symbol, image, QR, or any other specific format) of the data pattern to follow depending on its shape, and the setting value expression method (even if the same 'dot' symbol is used as the data pattern). It has meaning as a HEADER that determines the distance between cells, angle, or any other specific feature) and data processing method (general purpose/special purpose processing).

For example, if the reference pattern is one oval, the format of the data pattern is a symbol. At this time, the setting value expression method is linear if it is elongated parallel to the direction of progress of the data pattern (see FIG. 2), double-row type if it is vertically elongated (see FIG. 6), dispersed type if it is vertical but short (see FIG. 7), and if it is empty, it is in a row type (see FIG. 6). It is determined by data of 16 bit symbol type (see (a) in Figure 8), and if QR is included, it is typed into image type (see (b) in Figure 8) or QR type (see (c) in Figure 8) depending on the value. ) or other formats.

Data processing method, for example, even if it is the same image type, if the QR value in the reference pattern is 123, it can be used for general purpose, and if it is 124, it can be used to provide a service in a specific event app. For example, in an event app that provides coins upon NFT image recognition, it is necessary to select and process only QRs printed for the purpose of the event (QRs whose standard pattern has a value of 124).

The data pattern 130 includes a plurality of data cells sequentially arranged in the area of the code frame 110. Data patterns may be arranged sequentially within the area defined by the outline of the code frame and thus arranged in the image area 140 or along the outline of the image.

That is, one embodiment of the present invention includes a code frame 110 implemented as a closed curve extending according to the shape of the image or image area 140, making it easier to detect the position of the data pattern 130.

In addition, the present invention is characterized by more clearly displaying the starting point among data cells whose positions are specified by the code frame 110 through the above-described reference pattern 120. An example of such data extraction will be described with reference to FIG. 5.

Figure 5 is a diagram illustrating an example of data extraction according to an embodiment.

Referring to FIG. 5, the present invention sequentially sorts a plurality of data cells in a code frame 110 consisting of a closed curve according to set conditions. At this time, each data cell expresses bit data of '1' and '0' set according to the gap with other adjacent data cells.

To explain more specifically, if the data pattern 130 stores bit data of '0011...', a plurality of data cells are sequentially recorded in the direction set in the reference pattern 120, but the first data cell 131 The distance between the reference pattern 120 and the second data cell 132 and the first data cell 131 are expressed as '0' by making them less than the standard distance, and the distance between the second data cell 132 and the first data cell 131 is expressed as '0'. The distance to the 3rd data cell 133 is set to be greater than the standard distance and expressed as '1', and the distance between the 3rd data cell 133 and the 4th data cell 134 is set to be greater than the standard distance and expressed as '1'. do.

That is, in the present invention, the data patterns 130 are sequentially aligned in one direction based on the reference pattern 120, and the data values (e.g., bit data of '0' and '1') are divided through the interval of each data cell. ) can be expressed.

Additionally, in another embodiment of the present invention, the data pattern 130 can be arranged as multiple rows. This is explained with reference to FIGS. 6 and 7.

Figure 6 is a diagram showing another embodiment with data patterns arranged in multiple columns. Figure 7 is a diagram showing an example of extraction of data patterns arranged in a distributed manner.

Referring to FIG. 6, another embodiment of the present invention expands the width of the code frame 110 so that data cells can be arranged in two or more rows in the inner area, and can be configured to be arranged in a zigzag shape as shown in FIG. 7. there is.

In a multi-column data pattern, see FIG. 6, recognition of the data may begin horizontally along the lower column and proceed to the upper column.

That is, in the present invention, data cells can be arranged in one or two or more rows in the code frame 110 extending as a closed curve.

As previously explained, the data cell may express a value (for example, bit data) set according to the interval between data cells or the adjacent outline of the data cell and the outlines 111 and 112 on both sides.

Here, the outlines 111 and 112 refer to lines extending from both sides of the data pattern 130 to demarcate the area, and the outlines 111 and 112 on both sides form closed curves and are thus interconnected.

For example, the bit data of '01100...' refers to the first data cell 131 close to the reference pattern 120 as the second outline 112, and the second data cell 132 as the first outline 111. , the third data cell 133 was placed close to the first outline 111, and the fourth data cell 134 was placed close to the second outline 112 to express bit data of '0110'.

In addition, in another embodiment of the present invention, when data cells are arranged in two or more rows, in addition to the bit data expression method according to the distance between the outlines 111 and 112 on both sides of the code frame 110 described above, the data cells It is also possible to arrange bit data in a zigzag manner and express bit data according to the arrangement angle between data cells.

In addition, since the main point of the present invention is to specify the position and starting point of the data pattern 130 through the code frame 110 and the reference pattern 120, the data pattern and reference pattern are composed of images or symbols in addition to shapes. possible.

This is explained with reference to FIG. 8. Figure 8 is a diagram showing still other embodiments of the present invention.

Referring to FIG. 8, in another embodiment of the present invention, data patterns 130 are arranged to be aligned in one direction in a code frame 110 that has a predetermined width and length and extends in one direction. Here, the data pattern 130 can be of various shapes.

That is, the data pattern 130 is a symbol pattern 130' for expressing hexadecimal data (e.g., 062B3C254) as shown in (a) of FIG. 8, and a combination of color and image as shown in (b) of FIG. 8. It may include either an image pattern 130'' or a QR pattern 130''' composed of a QR image as shown in (c) of FIG. 8. In addition, various types of images, such as barcode patterns, can be patterned, and are not limited to the above examples.

The reference pattern 120 can represent the starting point of the above symbol pattern 130', image pattern 130'', and QR pattern 130'''. The reference pattern 120 may be manufactured to have a shape fused with the data patterns 130', 130'', and 130'''.

In addition, the reference pattern 120 has a shape that is fused with the above patterns (130', 130'', 130''') and has other patterns as shown in (b) and (c) of Figure 8 to increase discrimination. A display means 121 that can be identified is provided. Here, the display means has a data pattern, such as the length or shape of the outline, and a shape or numerical value that has identification.

That is, in the present invention, the reference pattern 120 and the data pattern 130 can be implemented as shapes, symbols, and images.

As described above, the present invention configures a code frame 110 to specify the position of the data pattern 130, but the code frame 110 can be extended in a straight line, curved line, or irregular line and freely transformed into a shape that matches the image. do. An example of a specific product is as shown in Figure 9.

Figure 9 is a diagram showing an example of an actual product to which the present invention is applied.

Referring to FIG. 9, the QR code to which the present invention is applied may be provided with an image included in an area adjacent to the code frame 110 in which the code frame 110 is formed to extend irregularly linearly so as to extend along the outer edge of the image. That is, the present invention may or may not include a separate image area.

For example, the present invention can form a separate image area 140 in an area in contact with the code frame 110.

Alternatively, it may be manufactured solely in the shape of the code frame 110 of the present invention and provided to be attached to an existing image or an empty space adjacent to the image. .

At this time, the code frame 110 is aligned with a reference pattern 120 that indicates a starting point when extracting data, and a plurality of data cells sequentially arranged from the reference pattern 120.

Therefore, the scanning terminal (not shown) captures the QR code, checks the reference pattern 120 in the captured image, sequentially checks data cells aligned in a set direction based on the reference pattern 120, and generates bit data. It can be extracted.

Therefore, in the present invention, even if distortion occurs in an image captured by a scanning terminal (not shown), data recognition errors do not occur as data cells are sequentially detected in a direction set based on the reference pattern 120.

In addition, in the present invention, in addition to the above-described embodiment, the data pattern 130 is not arranged in the inner area of the code frame 110, but rather the data pattern 130 is extended or protrudes from the outline dividing the code frame 110. Another embodiment forming may be provided.

10 to 12 are diagrams showing another embodiment of the present invention.

Referring to FIGS. 10 to 12, another embodiment of the present invention is characterized in that a code frame 110 extending in a closed curve shape, a reference pattern 120, and a data pattern 130 are formed as one body.

Referring to Figures 10 (a) and (b) among the drawings, the code frame 110 is colored and extends as a closed curve with a predetermined width, and the reference pattern 120 and data pattern 130 are codes. It may be expressed as a shape extending or protruding outward from the outline of the frame 110.

Here, the code frame 110 may be filled with a predetermined color in the space between the interconnected outlines as shown in (a) of FIG. 10, and may be implemented in an inverted shape of (a) in FIG. 10 as shown in (b) of FIG. It can be.

The reference pattern 120 has distinctiveness because the length extending along the code frame 110 is different from the data pattern 130.

The data pattern 130 is a plurality of data cells and has a shape in which a plurality protrudes from one outline of the code frame 110. Data cells can express bit data according to their mutual spacing.

Additionally, the code frame 110 can be modified into various shapes as shown in FIGS. 11 and 12. Figure 11 shows an example where the code frame 110 is manufactured as a spherical closed curve, and Figure 12 shows an example of a 'U' shape.

Here, the reference pattern 120 and the data pattern 130 can be combined in various ways according to the shape of the code frame 110 to express data.

For example, the reference pattern 120 is configured to have length, color, thickness, and shape different from the data pattern 130 so that it can be identified from the data pattern 130, and extends from the outline of the code frame 110. Or, it is formed to protrude.

In addition, the data pattern 130 protrudes only on one of the outer lines 111 and 112 on both sides of the code frame 110 (see FIG. 11), protrudes on both outlines 111 and 112 (see FIG. 12), or protrudes on both sides. It may be formed to protrude from the side in a zigzag manner (not shown).

When data cells protrude from the outlines 111 and 112 on both sides of the code frame 110 as shown in FIG. 12, bit data can be determined according to the connected outlines.

Additionally, the present invention may include another embodiment that can simultaneously display the location of data and the data extraction start point through the reference pattern 120. This is explained with reference to FIG. 13.

Figure 13 is a diagram showing another embodiment of the present invention.

Referring to FIG. 13, another embodiment of the present invention may include a reference pattern 120, a data pattern 130 having a plurality of data cells, and an image area 140 in which an image is arranged.

The reference pattern 120 has a shape that can be identified from the data patterns 130 as one of a colored figure, symbol, or image.

The data pattern 130 is formed so that a plurality of data cells are aligned according to the reference pattern 120 and a set rule. Here, the data cell may be entirely of the same color or a combination of two or more colors, or may be composed of one or more selected from two or more shapes (e.g., circles, triangles, polygons), symbols, and/or images.

Additionally, in the drawing, data cells are shown arranged in a square shape, but this is based on a square image or image area 140 and is not limited thereto.

That is, in another embodiment of the present invention, data cells can be defined as being aligned along the outline of an image that extends irregularly.

Therefore, the embodiment according to the present invention can apply images of various shapes by arranging data cells according to the shape of the image inserted into the QR code. In other words, the conventional QR code had very limited applicable designs, but the present invention provides the location of data recorded in the QR code through the code frame 110 and/or the reference pattern 120 in the form of a closed curve as in the above-described embodiment. Since the starting point can be specified and the arrangement of data cells according to the shape of the image is easy, more diverse designs can be applied to QR code.

Above, an embodiment of the present invention has been described, but those skilled in the art can add, change, delete or add components without departing from the spirit of the present invention as set forth in the patent claims. The present invention may be modified and changed in various ways, and this will also be included within the scope of rights of the present invention.
