At this time, the image acquisition device 111 is configured to further include an infrared LED or the like that can irradiate the infrared to the image data.

The data processor 112 analyzes the image acquired by the image acquisition apparatus, and decodes the digital data according to a predetermined rule, such as the position of the halftone group, as shown in FIGS. 6A to 6F.

In this case, the data processor 112 may shift or rotate the image according to the recognition direction. If the image is misaligned, the data processor 112 recognizes the image area CS based on the reference network 101 and, if the image is rotated, the image. It will be recognized throughout the calibration process.

In particular, when the image is rotated, the group of dots 101 and 102 are matched with 45 pieces of image data rotated in a predetermined angle, that is, from 1 ° to 45 ° in 1 ° increments. The data can be recognized.

Meanwhile, the sound source generation signal unit 120 is configured to transmit a signal to the sound source playback device 200 so that the sound source playback device 200 reproduces the corresponding sound source according to the digital data recognized by the data recognition unit 110. .

The sound source generation signal unit 120 is possible by a variety of methods, such as wired or wireless, depending on the transmission method.

The sound source reproducing apparatus 200 is a device for generating a corresponding sound source according to the signal received from the sound source generation signal unit 120, may be configured integrally or separately, and may be configured in the same manner as the existing karaoke apparatus. At this time, of course, the sound source reproducing apparatus 200 further includes a communication unit 210 that can communicate with the sound source generation signal unit 120.

On the other hand, digital data corresponding to each sound source recognized by the song selection device according to the present invention is formed and printed in the printed matter 10 such as a songbook by the following method.

In general, the printed matter is printed by a combination of dots of three colors, such as R, G, and B, C, M, Y, and K, or monochromatic inks, 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.

When forming image data with a combination of such fine dot dots, it is necessary to configure the constant image data so as to occupy the smallest area possible so as not to be visualized. Since the image data are 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.

A method of forming image data relating to a sound source list including digital data corresponding to each sound source comprises: an image region dividing step of dividing the image data into a plurality of image regions based on a resolution of a printing apparatus; Sub-area division for 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 sub m integers of 2 or more in the vertical direction. Steps; A dot group designation step of designating continuous print dots as one dot group with a margin in at least one of a horizontal direction and a vertical direction in the sub area based on a printing dot 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.

In this case, the image area and the sub area may be formed by various methods such as polar coordinates as well as horizontal and vertical directions.

In addition, a method of forming image data relating to a sound source list including digital data corresponding to each sound source includes: an image region dividing step of dividing the image data into one or more image regions based on a resolution of a printing apparatus; A sub area dividing step of dividing the image area into a plurality of sub areas based on the resolution of the printing apparatus; A dot group designation step of designating a plurality of print dots as one dot group based on printing dots according to the resolution of the printing apparatus while having a margin in the sub area; The dot group is formed by forming a dot group in each of the sub-regions according to the digital data.

Meanwhile, as described above, the method of forming image data including digital data corresponding to each sound source may be implemented by an executable computer program, and the computer program may be stored in a storage medium such as a CD.

Image data formation and printing

First, the image data including the sound source list is divided into a plurality of image areas CS based on the resolution 1200DPI of the printing apparatus. Here, the image data does not include the underlying image data including patterns of sound source lists, pictures, figures, and letters to be printed on the printed material of the songbook, and the patterns of sound source lists, pictures, shapes, and letters to be printed on the same printed material. It can be composed of image data having only a pattern formed of a group of dots corresponding to the printed matter.

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. 4. At the same time, the data is divided into n x m sub-regions SS.

4 and 5 are divided into five sub-areas each vertically and horizontally in one image area of the sound source list, FIG. 4 shows only two reference network groups, and FIG. 5 shows the maximum network of groups. It is 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 4 and 5 the dot group is composed of two in the transverse direction, four margins.

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.

On the other hand, the image area CS may be divided with a margin so as to 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.

4 and 5, subregions NCS for displaying such as NULL in digital data may be additionally formed at the leftmost and lowermost portions of the image region CS.

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

6A to 6E illustrate an example of forming subregions SS in which positions of the halftone groups are displayed corresponding to each bit of each digital data.

In other words, Fig. 6A shows 00000000 as binary data, Fig. 6B shows 00000001, Fig. 6C shows 00000010, Fig. 6D shows 00000011, Fig. 6E shows 00000100, and Fig. 6F shows NULL.

On the other hand, the image area (CS) having the digital data corresponding to each sound source as described above is repeated in a predetermined area on the printed matter (1) to facilitate the recognition by the song selection apparatus 100, as shown in FIG. In this case, the sub area SS in each image area CS is recognized by the reference network 101. In particular, as illustrated in FIG. 3, digital data corresponding to each sound source may be printed in the sound source list, such as overlapping with each sound source or in a neighboring area.

In FIG. 7, the grid indicated by a dotted line is actually a non-printed 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.

As shown in FIG. 7, the image data including digital data used when printing the sound source list 11 may be printed on the printed material 10 on which the sound source list 11 is printed. Sub-image data consisting of a pattern formed of a dot group corresponding to the size of the printed matter 10 without including image data that forms the background including patterns such as a pattern, image data to be printed, or patterns such as pictures, figures, and characters to be printed. It can be configured as.

In this case, the sub image data including the digital data may be combined with the image data including the pattern and then printed together, or the image data including the pattern may be printed first and then separately printed. At this time, the synthesis method of the image data can be synthesized in various formats such as PDF file, 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 perform printing 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.

As described above, when the ink used for printing the dot group is carbon, it can be accurately recognized using an infrared LED.
