An image data forming method for forming image data having digital data so that the image data can be transferred to a moving image, an image data printing method for printing image data having a digital code, and image data recognition for recognizing an image in the printed matter as described above. It is about a method.

Whatever the printed matter, the printed matter is formed by the printing of figures, letters, pictures and the like on a printing medium such as paper by a printing apparatus or the like. At this time, the printing apparatus generally combines the color inks such as C (red), M (blue), Y (yellow), K (black) (or R, G, B, black, etc.) in the unit of dots to print the pattern. Will print to

Meanwhile, the pattern printed on the printed matter may be recognized by an image recognition device such as a barcode, and may be implemented to include digital data such as a price and an address.

As a method of printing so that the pattern printed on the printed material to display the specific data as described above, there is a method of printing overlaid with other patterns using the ink of a special component in addition to the method of printing with a bar code so far.

However, the barcode does not overlap with other patterns, and thus has to be printed after a predetermined area is designated on the printed matter, thereby deteriorating the appearance.

In addition, the method of overlapping with other patterns may affect other patterns such as darkening the color of the printed patterns or changing colors, and may damage the appearance, and use expensive printing costs by using a printing ink having a special ingredient. Difficulties must be followed. In addition, there is a problem that an area that does not recognize data due to the influence of other patterns occurs.

An object of the present invention is to provide an image data forming method having digital data capable of forming image data having digital data without damaging the underlying image image at all.

Another object of the present invention is to provide a printing method capable of printing to include image data having digital data without damaging the pattern to be printed together.

Still another object of the present invention is to provide an image data recognition method capable of accurately recognizing image data printed by being patterned according to the resolution of a printing apparatus.

The present invention was created to achieve the above object of the present invention, the present invention comprises: an image region dividing step of dividing into a plurality of image regions based on the resolution of the printing apparatus; A subarea dividing step of dividing the image area into n or more integers of 2 or more in the horizontal direction based on the resolution of the printing apparatus, and dividing the image area into m or more of integers of 2 or more in the vertical direction and dividing the image area into n × m subareas; ; A network group designation step of designating one network group by connecting successive printing meshes based on the printing meshes according to the resolution of the printing apparatus while having a margin in at least one of a horizontal direction and a vertical direction in the sub area; Disclosed is an image data forming method having digital data including a dot group forming step of forming a dot group in each sub-area corresponding to digital data.

After the halftone group forming step may be configured to further include an image combining step combined with the image data.

At least one of the halftone groups may be a reference halftone group capable of recognizing the image area, and the reference halftone group may be configured differently from the shapes of other halftone groups. In addition, the dot group may be formed by an outline.

The resolution of the printing apparatus may be configured to 1200 DPI.

Hereinafter, an image data forming method, an image data printing method, and an image data recognition method according to the present invention will be described in detail with reference to the accompanying drawings.

In general, the printed matter is printed by a combination of dots of three primary colors such as R, G, and B, or four colors or monochromatic inks such as C, M, Y, and K at a resolution of 600 DPI, 1200 DPI, 3000 DPI, or the like. Here, DPI refers to the number of dots printed per inch. The size of one dot is about 0.02mm × 0.02mm at 1200DPI.

In order to display digital data using such fine dot dots, a sufficient amount of data can be represented so as not to be limited by the size of the printing surface or the number of pages, and image data capable of informing the information can be created.

At this time, the shape of the halftone is different depending on the manufacturer of the printing device, that is, circular, diamond, hexagon, etc., but considering the extremely fine size of the halftone does not significantly affect the shape of the halftone.

Note that when forming image data with a combination of such fine dot dots, it is necessary to configure the image data to occupy the smallest area possible so as not to be visualized. Since the image data is a combination of dots, it is important to distribute the image data evenly without overlapping and continuous.

Therefore, in the present invention, when the printing halftone is used alone, the printing halftone is displayed by a laser in a printing apparatus (a machine for manufacturing the original plate for printing). Since there is a possibility that it may not be well expressed, it is necessary to form one dot group by attaching two or more dots in succession, such as two to four, to form image data.

In addition, the above-described groups of dots are defined as a bit concept of binary numbers used for digital data and correspond to the positions of the dots and the data bits, so that accurate information can be expressed, but there is no risk of loss and it is not visible.

On the other hand, digital data is required by considering that data is processed in the most basic bit or byte (8-bit) unit when digital data is read by an image recognition device such as a camera and the digital data is recognized. Considering this, select the number of halftone groups.

In order to uniformly distribute the unit information of the displayed digital data and prevent it from being visible, the ratio of the halftone group where the printing ink displaying the unit information is displayed and the margin around which the ink is not displayed is about 1: 1.5 or more. Make sure that the space occupied by the margin is larger than that occupied by the halftone group.

According to the present invention, there is provided a method of forming image data including digital data, comprising: an image region dividing step of dividing the image data into a plurality of image regions based on a resolution of a printing apparatus; The image area is divided into n or more integers of 2 or more in the horizontal direction based on the resolution of the printing apparatus, and divided into n or more integers of 2 or more in the vertical direction and divided into n × m sub areas. Wow; A half point group designation step of designating adjacent halftones as one halftone group in the sub-area, having a margin in at least one of a horizontal direction and a vertical direction, the printing halftone according to the resolution of the printing apparatus; The dot group is formed by forming a dot group in each of the sub-regions according to the digital data.

Hereinafter, an embodiment will be described with reference to a method for forming image data including digital data according to the present invention.

Example

Image data formation

First, as illustrated in FIG. 1, the image data is divided into a plurality of image areas CS based on the resolution 1200DPI of the printing apparatus. In this case, the image data is formed of a group of dots corresponding to the printed material without including the pattern of the image, the figure, the letters, etc. to be printed on the same printed material and the image data that includes the patterns of the pictures, figures, and letters to be printed on the printed material. It may be composed of image data having only a pattern.

At least a part of the image area CS is divided into n or more integers of 2 or more in the horizontal direction based on the resolution of the printing apparatus, and divided into m or more of integers of 2 or more in the vertical direction, as shown in FIG. To be divided into n x m sub-regions SS.

2 and 3 are divided into five sub-areas SS in each of the image area CS horizontally and vertically, FIG. 2 shows only two reference network groups, and FIG. The counties are shown.

In the sub area SS, one half point group 101 and 102 has a margin in at least one of a horizontal direction and a vertical direction, and connects a plurality of continuous half points based on a half point according to the resolution of the printing apparatus. To be specified.

In this case, in order not to be visible when the halftone groups 101 and 102 are printed, it is preferable that the ratio of the margin and the halftone groups 101 and 102 in the sub area CS is 1.5 or more. In the case of Figures 2 and 3 the dot group is composed of two in the horizontal direction, the margin is four.

That is, the group of dots 101, 102 is composed of two or more dots in succession in at least one direction in the horizontal and longitudinal direction, the margin is three or more dots in succession in at least one direction in the horizontal and longitudinal direction. It can be configured as.

The image area CS may be recognized separately from the neighboring image area CS. Accordingly, at least one of the halftone groups 101 and 102 may be a reference halftone group 101 capable of recognizing an image area CS, and the reference halftone group 101 may be different from the shape of another halftone group 102. can do.

That is, the reference point group 101 may be formed in a 'b' shape, the other group of dots 102 may be formed in a 'b' shape, and the data of the halftone groups 102 may be configured in various ways. It may be to correspond to each shape.

The dot group may be formed by an outline method according to a printing method, and the inside thereof may be filled or emptied.

Also, in FIGS. 2 and 3, a sub-area NCS for displaying such as NULL in digital data may be additionally formed at the left and bottom of the image area CS.

The dot group 102 is formed in a corresponding subregion SS among the subregions SS forming the image region CS according to the digital data to be included.

4A to 4E illustrate an example of forming sub-regions CS in which the positions of the halftone groups are displayed corresponding to each bit of each digital data.

In other words, Fig. 4A shows 00000000 as binary data, Fig. 4B shows 00000001, Fig. 4C shows 00000010, Fig. 4D shows 00000011, Fig. 4E shows 00000100, and Fig. 4F shows NULL.

Meanwhile, as shown in FIG. 5, the image area CS having the digital data as described above may be repeatedly formed in a predetermined area on the printed matter 1 so as to be easily recognized by the image recognition device. The sub area SS in the image area CS is recognized by the reference network 101. In FIG. 5, the grid indicated by the dotted line is actually an unprinted line and a line drawn for convenience of description. However, it can of course be printed to set the standard for each dot group. Grid lines shown in the other drawings may also be printed for convenience of description, or to set the standard of each dot group.

Image data print

As shown in FIG. 5, the image data including digital data as described above includes image data that forms a background including a pattern such as a figure, a figure, and a character to be printed on the printed matter 1, and a figure, a figure, and a character to be printed. It may be composed of sub-image data consisting of a pattern formed of a group of dots in correspondence with the size of the printed matter 1 without the pattern of the back.

In this case, the sub image data including the digital data may be printed together after being combined with the image data including the pattern, or may be separately printed after the image data including the pattern is first printed. At this time, the synthesis method of the image data may be synthesized in various formats such as a PDF file, a BMP file. Regardless of the printing method, when printing sub-image data, carbon-based printing ink should be used among general printing ink.

If you look at the components of a normal printing ink, you can see that the four basic color inks, red, blue, and yellow, do not contain carbon but only black.

And if you combine the sum of the three colors: red, blue, and yellow in the same proportions, you get black. The present invention can print by dividing image data and sub image data by using the component characteristics of the printing ink.

In addition, the printing ink used when printing several colors should be printed in a certain order. First of all, black ink containing no carbon components blended with the three primary colors should be used, and lastly, sub-image data having a pattern composed of halftone groups in black containing carbon components should be printed.

In addition, it is most preferable to adjust the print density to 4% in the last sub-image data used at this time. If the print density is higher (more than 5%), it affects other colors. If the print density is lower (less than 3%), the image recognition device may not recognize the ink because the ink is not evenly printed during printing.

Image data recognition

When the print group containing the carbon element is used as the dot group group ink, the image recognition device may accurately recognize the digital data regardless of the basic background image printed using the infrared LED.

After acquiring an image by an image recognition device such as a scanner from the printed matter including the digital data as described above, the acquired image is analyzed to decode the digital data according to a predetermined rule as shown in FIGS. 4A to 4F. do.

In this case, the image recognition device may shift or rotate the image according to the recognition direction. If the image is misaligned, the image recognition device recognizes the image area CS based on the reference network 101 and corrects the image if the image is rotated. It is recognized through the process.

In particular, when the image is rotated, the dot group 101 and 102 store image data rotated by a predetermined angle, that is, from 1 ° to 45 ° in 1 ° increments, to match the data. Digital data can be recognized.

Meanwhile, the printed matter may be applied to various fields such as language guides for language guidance, teaching aids for early childhood education, etc. At this time, the printed matter including the digital data may be recognized by an auxiliary device having an image recognition device. Can be.

In this case, the auxiliary device may be configured as an audio device for reproducing an English expression corresponding to the printed Korean expression of the printed matter according to the recognized digital data.

That is, as shown in FIG. 5, the user recognizes digital data printed in each specific area by using an acoustic device having an image recognition device, and different sounds are reproduced according to the recognized digital data.

The present invention has the advantage that the digital data printed at a resolution that cannot be identified with the naked eye is printed together with the pattern, thereby forming or printing the image data including the digital data without damaging the appearance of the printed matter.

The present invention has the advantage that can display a large amount of digital data in the state of overlapping the pattern of the printed matter.

The present invention has the advantage that digital data can be recognized without being affected by the printing state of the printed matter.

Although the preferred embodiments of the present invention have been described above by way of example, the scope of the present invention is not limited to these specific embodiments, and may be appropriately changed within the scope described in the claims.
