The present invention prints digital coordinates on the printing surface on a two-dimensional plane by printing the half-point coordinates, which are not visible in a general view, so that no traces remain in the prototype printed on the two-dimensional plane. The present invention relates to a method of printing and inputting digital code of position information which can be made possible.

In addition, the present invention includes a multimedia (sound, video) function in the digital code of the printed matter using a portable device equipped with a camera to recognize the coordinates and converts the information corresponding to the recognized coordinate values into a three-dimensional sound The present invention relates to a printed matter to which a character position information digital code is input and a recognition device for recognizing the same, so as to simultaneously achieve a reading effect that can be heard by the ear.

The recent invention of computers and the continuous development of technology have made the world more convenient by promoting the invention of means to reproduce each information or expression that people see, hear and speak. Among them, the transfer of knowledge and information through print media has led to the invention of paper books through the invention of electronic books using computers.

However, the method of converting the information of the texts and pictures recognized on the plane into a higher level of words and sounds without using a computer has been tried many times, but it is not very effective in terms of production cost and practicality.

For example, braille books (recognized by tactile sense) and scanning methods (recognized by predetermined schedule rules (e.g., barcodes)) are widely used, but they are not widely used due to their high production cost and their ease of use. I can't.

In the case of the scanning method, when printing a special code or printing a character, a special code or dot that is not necessary, with restrictions on the size of the printed character (should not exceed the scanning range of the scanner) or the shape (handwriting or flowing letters) There is a hassle such as printing, and the scanner has a disadvantage in that it is inconvenient to use because it can be recognized by accurately scanning.

In the case of the coded image e-book disclosed in Utility Model Registration No. 036146, it is impossible to recognize it by printing a code using a special printing ink or overlapping with other colors when printing the code. Because of the need for an auxiliary device, it is difficult to use because it is not universal or easy to carry, and there is a limitation of the print media (not being recognized depending on the size and geology of the print).

Accordingly, the present invention is to solve the above-described conventional problems, the present invention is not only to read the printed matter, such as a character or a picture printed on a two-dimensional plane, It aims to provide three functions of reading, listening, and reading at the same time.

The technical problem to be achieved by the present invention is to allow the expression of coordinates to be free, and to be manufactured at a relatively low cost by using a general printing ink that is generally used by anyone, so as not to overlap with other colors.

Also, since the printing of coordinates is not visualized so as not to affect other printing colors or shapes, the range of coordinates generated without being bound by the thickness or geology of the print media is set to the maximum range that can be maximized by the printing technique. .

In addition, by matching the coordinate information with the Unicode (universal common character array information) used for the digitization of the character is to be independent of the color or printing method.

In addition, the present invention is a recognition device for recognizing the coordinates to reproduce the sound is also simple in structure and easy to carry, the recognition device camera can freely vary the focal length and distance to the recognition medium, in addition to the reproduced sound In the case of a video, it can be reproduced as a wirelessly connected (Bluetooth) video (PC monitor or TV, etc.).

In order to achieve the above object, the present invention prints halftone coordinates consisting of 64 points within a horizontal and vertical 0.1mm2 for generating position information of a target object on a two-dimensional plane. It provides a method of printing the character position information digital code of a printed material, characterized in that the printing of carbon black general ink at a print density of 5 to 3%, which is not visible, so as not to affect.

In addition, the present invention converts the data-related file information object of the page on which the character position information digital code printed by the above printing method into a PDF image file, and the resolution capable of realizing the PDF image file on a computer screen Converting to a BMP image file according to (75dpi), and setting an area according to the position of the BMP image file and assigning a number to each area sequentially to generate a coordinate code file matching the object included in the page.

According to the present invention, there is provided a digital code printing method for character position information of a printed matter, a digital code production method for converting character position information of a printed matter into sound information, a printed matter produced by the method, and a digital code for converting character position information to sound information. Provided is a digital code recognition device for recognizing an input printed matter.

First, a method for manufacturing coordinates according to the present invention will be described.

The present invention provides a sound through a separate recognition device for a picture or text to be made or other information inputted on a plane made of any printable material other than the object or paper such as a printed poster or booklet, or an object such as a picture or a video. In order to reproduce the video, it is necessary to create location information where the information is located.

The above position information may be determined in advance in specific coordinates. The necessary information may be divided into half-point coordinates, page information, and other necessary information for generating position information of a target.

Also, considerations when creating (creating) the necessary coordinates should be set in advance so that there are no errors or mistakes when recognizing the size of the coordinates, the shape, the arrangement of the information, etc., and it should be distinguishable from the general printing information. .

In determining the coordinate size, considering the camera size, focal length, and recognition range of the input unit of the recognition device, the size of the dot when using the most versatile density in general printing is considered.

As shown in FIG. 2, the printable point size is 8 to 24 μm (1 μ: 1/1000 mm), but the size that can be identified with our eyes is about 0.1 mm. do.

In general, the most common print density ranges from 1,200 DPI (DPI: Density of 1200 dots per 1 inch to 1 inch), up to 3,000 DPI, and between 120 and 180 LPI (1 inch per inch). Although the number of lines to be taken) is used, the present invention uses the example of generating coordinates based on the most widely used 1,200 DPI and 150 LPI.

For example, assuming a print density of 1,200 DPI, four dots can be printed at 0.1 mm, and in the case of 0.4 mm 2, 16 dots can be expressed in two lines.
In the present invention, since 32BIT information is sufficient when considering the maximum possible number of coordinates to be printed, the size of the minimum recognizable coordinate is set to 0.4 mm2 and the DATA is processed as 32BIT.

In addition, it is most preferable that the information is formed in a circular or rhombic shape in order to accurately read all the information according to the tilting or recognition direction of the recognition device camera, and special information is needed to distinguish the beginning and the end of the information. This can affect the amount of, so we make a triangular group of information and arrange the actual utility information on the right and bottom sides so that the correct information can be recognized no matter which direction is read. Coordinate information actually generated here is as shown in FIG.

In this way, the same 9 pieces of information can be arranged in 1.2mm2, and when reading this information with the recognition device, if the circle of the shape of the recognition device is formed in the shape of 1.2mm2, one correct information can be recognized in any position or direction. You can do it.

On the other hand, in the production method of the coordinates in the printed matter, as shown in Figs. 4 and 5, after editing the data edited in the book (printed material printed on the two-dimensional plane) to the image file (PDF), the file is converted into a computer screen. Convert to bmp file by lowering to 75dpi resolution. At this time, the area of the object data is set in the converted bmp file, and each area is numbered sequentially.
Coordinate formation in the object uses the page, horizontal, and vertical information in order and uses the coordinates directly. For example, in FIG. 4, the letter part 'CAR' sets the number information as the first 1 of page 1, and the car image part sets the sequential number information as shown in the second of page 1, and if it is coded immediately, the coordinate code is (E.g. 001001, 001002,…)

The reason why the data edited in a book is not converted into an image file but converted into a PDF file and then converted into an image file is used according to the editing program used to directly convert the edited book data into an image. Because fonts and images may be changed, it is necessary to go through one more process to obtain the most accurate image file.

The bmp file image thus created is stored by inputting CODE (eg, 001001) to each word, sentence, or picture in the page using a code program. At this time, the assigned code file is collected sequentially to generate a file for outputting coordinates which is applied when printing the relevant sentences and figures. (See FIG. 6).

Another method here is to use the (Unicode) character digital information of the character itself to match the coordinate value, so that the coordinate information alone can be replaced by the Unicode information itself without additional coordinate information. In this case, it is possible to achieve the object of the present invention by separating the character information even with a general printed matter without adding additional coordinate information printing information.

Referring to the coordinate printing method according to the invention as follows.

The characteristics of general printing inks printed on a two-dimensional plane include inks that contain carbon in their components by color. The coordinates are printed by selecting the order of mixing and printing well utilizing the characteristics of these inks.

For example, if you print the coordinates in white with carbon content, you have to print for the first time in order not to affect other colors.

And when printing the coordinates using the black ink containing the carbon component should be distinguished from the commonly used black ink. The black ink for printing the coordinates and the black ink used for the general color use the separated ink so as not to overlap, and the black ink used for the general printing uses the ink containing no carbon component.

The black ink containing no carbon is obtained by combining the three primary colors of ordinary ink. The sum of the three primary colors uses the principle of black.

In order to avoid affecting other colors due to the printing of the coordinates, it is preferable to print the density less than 5%. However, if the printing technique is less than 3%, the printing quality may be affected and the ink may not be printed evenly on the entire paper to be printed. In some cases, it is desirable that the print density be maintained at a concentration of 5% to 3%, and the print order may be printed at the end so that the recognition rate shows the best quality.

Referring to the voice and video data production method according to the present invention.

As shown in Fig. 6, the audio or video data is cut to match the CODE given to make the position coordinates as described above, and each file is given a file name (for example, 0001.wav), and these are combined to generate one file. The file is made into digital data using a specific program (sound forge / 2003 Sony company), and then compressed into a memory device to be used and put in the memory device. At this time, it should be noted that a lot of compression has the advantage of reducing the amount of data, but it is easy to become a mechanical sound by losing the original sound component. You should find and use the best compression ratio for your original sound.

In the present invention, when compressing a sound, the compressed information is applied by applying the most suitable ratio in accordance with the amount of sound information and the capacity of the memory device, without using a specific ratio.

The printed matter to which the digital code is input is converted to sound information through a separate recognition device for recognizing the digital code and output.

As shown in FIGS. 8 and 9, the character position information digital code recognition device 10 is formed of a precise CMOS optical lens connected to an IC circuit, and configured to adjust a focal length to recognize a target coordinate. ) And three LEDs 24 arranged in a triangular shape around the camera 22 to recognize only the carbon component printed on the position coordinates of the object and reflect it to the camera 22. An input unit 20 for obtaining a;

Memory and video corresponding to the data file of the position coordinate are compressed digital sound data and inputted in advance, and the information obtained through the input unit 20 and the information of the storage device 32 are compared and matched with each other. Central processing unit 31 for transmitting information to the recognition device 10, consisting of a plurality of control buttons external input device 35 for controlling the central processing unit 31, a built-in battery or a power connection connected to an external power source A control unit 30 including a terminal 34 and a power switch 33 for controlling to supply power required for each unit;

Speaker or earphone jack for reproducing digital information as a sound according to the processing signal of the central processing unit 31, Wireless video transmitting device for transmitting video information to a display device of a separate computer or TV using a radio frequency An output unit 40;

The recognition device having the above-described configuration allows the data related file information such as a word, a sentence, or a picture printed on a corresponding page of the printed matter with position information digital code to be recognized through the camera 22 of the input unit 20, By comparing the recognized coordinate values stored in the storage device, the corresponding sound or video may be output to the outside through the output unit 40.

The input unit 20 of the recognition device 10 should be well adjusted to match the size of the LED and the intensity of the light and the focal length of the camera, and the LED light is wrapped around its outer circumference to protect other lights from being affected. When you select the area where the coordinates are printed, if the light shines through the input part LED, only the carbon component is reflected to read only the coordinate information from the camera lens.

In this case, be careful to use three LEDs in triangle composition to read accurate information in the center even if the light is driven in any direction so that the input part can recognize the information accurately through the LED reflecting the carbon component. So that the three lights are centered in the center so that they can read the correct data from the center.

Otherwise, if only two LEDs are used on the left and right side, the center data should be correctly recognized and tilted up and down only when the printed information is perpendicular to the printed information and when the left and right slopes. In this case, the focus is not centered on the point, and thus accurate information cannot be read.

As shown in FIG. 12A, the left and right tilts do not affect the camera recognition range of the input unit, but when tilted up and down, the recognition range is blurred and cannot be correctly recognized.

As shown in FIG. 12B, even when the camera of the input unit is tilted up, down, left, and right, accurate coordinates can be read without change in the central recognition range.

On the other hand, the recognition device 10 includes an input unit capable of reading coordinates, and compresses a voice or a video using a pre-stored memory device for reproducing digital sound data, a speaker for reproducing digital information as a sound, an earphone jack, or a radio frequency. The ability to send video information to a separate computer or TV screen is integrated into a single device, all integrated into a single device, making it easier to carry and use.

The external input terminal 35 connected to the control unit 30 of the recognition device 10 and controlling the same may additionally use various functions by using a plurality of on / off operation switches that can be separately operated from the outside.

The operation switch of the external input terminal 35 adds a repeating function button for continuously outputting the once output information, and a pair of symmetric voice information (English → Korean or Korean → English) when the voice information is inserted into the memory device. If the function switch is operated, it can be distinguished by the translation function button to find and transmit the memory symmetrically to the corresponding address, and the whole listening function button to send all the voice information contained in the memory from the beginning to the end. .

As such, the present invention prints the dot coordinates so that the digital code is not visible in a general view so that no trace remains in the prototype of the printed matter printed on the two-dimensional plane. Can be read through.

It also prints code coordinates separated by sound or video data with multimedia (sound, video) function on paper or other printable two-dimensional plane, and uses coordinates using a portable recognition device equipped with a camera. And the information corresponding to the recognized coordinate value is converted to the three-dimensional sound by using the recognition device to achieve the reading function that can be listened to the ear at the same time. The user can be simultaneously provided with three functions of viewing, listening, and reading, and the recognition device can reproduce sound and video in real time in association with a separate speaker and a display device.

As such, the present invention is not limited to simply transferring to a digital medium for permanent preservation of the contents contained in paper prints, and not only the existing paper but also the originals of all prints without being damaged, while maintaining the multimedia (sound, video) function. There is an advantage in that it is possible to digitize the general paper (paper) media to be delivered.

In addition, conventionally, a method of providing a sound service through a multimedia device capable of scanning and recognizing a barcode and outputting the digital information to an external device, while the present invention provides a digital code invisible to all existing prints / publications. By printing halftone dots, it is possible to produce the original prints in the same way as normal prints without leaving any marks, so that editing data and master sound published in the shortest time can be edited. Output is required, and the printing cost is low because only 1 degree of spot color printing cost and sound processing cost are additionally added.

In addition, a recognition device that prints an additional 1 degree on a two-dimensional plane, converts it into a digital code, and inputs it to recognize a digital code provides sound text information through a speaker or headphones built in according to the processing instruction. Equipped with scan function, multimedia (sound) service function, translation key and repetition key, the printed material is visually read and the contents are serviced by voice in real time, so that not only learning effect but also visual impairment due to visually impaired people, illiterate people and elderly people They can also read through hearing and have a great effect on communication between people who speak different languages.
