Mode for the Invention [20] Hereinafter, an apparatus for selecting song according to the present invention will be explained in more detail with reference to the attached drawings. [21] As shown in FIGS. 1, 2 and 3, the apparatus 100 for selecting song according to the present invention comprises a data recognition unit 110, and a sound source generation signal unit 120. [22] The data recognition unit 110 is a device for recognizing digital data indicating one of the sound sources printed in a printed material 10 printed with a sound sources list 11 and digital data respectively indicating the respective sound sources.

[23] The data recognition unit 110 includes an image acquiring device 111 such as a scanner for acquiring an image, a digital camera and a infrared ray camera, and a data processing unit 112 for recognizing digital data in the image acquired by the image acquiring device 111.

[24] The image acquiring device 111 is constructed to recognize an image in the printed material 10 printed with a sound sources list 11 such as a song book, preferably to recognize an image data printed by ink including carbon which may react with the light radiated by the infrared ray LED. Herein, the image acquiring device 111 may be further provided with an infrared ray LED, etc. which may radiate infrared ray to the image data.

[25] The data processing unit 112 analyzes the image acquired by the image acquiring device, and decodes the digital data referring to the predefined rule such as a position of dot group, etc. as shown in FIGS. 7 to 12.

[26] Herein in case that the image may be deviated or rotated according to the recognition direction, the data processing unit 112 may recognize the image region CS referring to the reference dot group 101 when the image deviated, and after the process of revising the image when the image rotated.

[27] Particularly, when the image is in a rotated state, the image may be recognized by matching with pre-stored image data, the image data corresponding to the dot groups 101, 102 rotated by 1° withing a certain angular range of 1°~45° in order to enhancing the recognition rate.

[28] Meanwhile, the sound source generation signal unit 120 transfers a signal to generate a sound source corresponding to the digital data recognized by data recognition unit 110 to a sound generating device 200.

[29] The sound source generation signal unit 120 may transfer the signal by a various method such as by a cable or by wireless.

[30] The sound generating device 200 is a device for generating a sound source corresponding to the signal transferred from the sound source generation signal unit 120, may be implemented as an one body or a separate construction, or the similar existing facilities of Noraebang. Herein, the sound generating device 200 may be further provided with a communication unit 210 for communicating with the sound source generation signal unit 120.

[31] In addition, the sound generating device 200 may include a sound generating unit

220 such as a speaker, and a image display unit 230 for generating an image such as a monitor in order to simultaneously generating an image together with a sound source.

[32] The apparatus 100 for selecting song may be implemented as a sound generating device 200 generating at least a part of the sound source corresponding to the digital data recognized by the data recognition unit 110 in order to select a song after a user hear a sound source in advance, or further provided with an additional auxiliary sound generating device.

[33] In addition, the sound generating device 200 may display information of the sound source corresponding to the digital data recognized by the data recognition unit 110.

[34] In addition, the apparatus 100 may include a handling unit 130 for controlling the sound source generation signal unit 120 to generate and transfer a control signal to the sound generating device 200 by a user's handling so that a user may control whether to generate a sound source.

[35] Meanwhile, the digital data corresponding to the respective sound source recognized by the apparatus for selecting song according to the present invention may be formed and printed on the printed material 10 by the following method.

[36] Generally, a printed material is printed by combining dots in 3-color ink such as R,

G, B, 4-color ink such as C, M, Y, K, or single color ink with a resolution of 600 DPI, 1200 DPI, or 3000 DPI. Here, the DPI indicates the number of dots printed per inch. In the case of the 1200 DPI, one dot generally has a size of approximately 0.02mmx0.02mm.

[37] In order to display digital data by using the minute dots, required is image data that can represent a large amount of data and make the data as information regardless of the size or the number of printed materials.

[38] Here, the dot may have various shapes such as circle, diamond, and hexagon according to manufacturing companies for a printing device. However, with consideration of the size of a very small sized dot, the shape of the dot does not greatly matter.

[39] When forming image data by combining a plurality of minute dots, a certain image data has to be configured to occupy the least area as possible so as be invisible. It is more important to non-consecutively and evenly distribute each image data without overlapping each other.

[40] If one printing dot is used, a printing device (a machine for manufacturing a original printing plate) displays a printing dot by laser. Here, one printing dot may be printed with ink particles not be well-represented due to its too small size. Therefore, the present invention provides a method for forming image data including digital data by forming one dot group by consecutively arranging dots in two or more such as 2-4 dots, etc.

[41] Furthermore, each dot group is defined as bits represented in '0' or T, and the position of the dot group corresponds to data bits, thereby precisely representing information with an invisible state and without loss.

[42] Generally, digital data has its digitalized pattern be read by an image recognizing device such as a camera, in the unit of bits or bytes (one byte is 8 bits). With consideration of this, the number of dot groups is determined according to a required amount of digital data.

[43] In order to evenly distribute each unit information of displayed digital data with an invisible state, a ratio between a dot group on which printing ink is displayed for unit information, and a margin around the dot group where ink is not displayed has to be 1:1.5 or more. That is, the margin has to be configured to occupy a larger area than the dot group.

[44] A method for forming image data regarding the sound sources list including digital data corresponding to the respective sound sources comprises the steps of: dividing image data into a plurality of image regions according to a resolution of a printing device; dividing the image regions into nxm sub-regions by dividing the respective image regions at least n times (n: integer of two or more than) in a horizontal direction, and at least m times (m: integer of two or more than) in a vertical direction according to the resolution of the printing device; setting a dot group by connecting printing dots consecutive to one another based on one printing dot according to the resolution of the printing device, with having a margin in at least one direction of the horizontal and the vertical directions; and forming dot group in the corresponding sub-region according to digital data.

[45] Here, the image region and the sub-region may be formed in various manners such as polar coordinates as well as horizontal and vertical directions.

[46] According to another aspect of the present invention, a method for forming image data image data regarding the sound sources list including digital data corresponding to the respective sound sources, comprises the steps of: dividing image data into a plurality of image regions according to a resolution of a printing device; dividing the respective image regions into nxm sub-regions by dividing the respective image regions at least n times (n: integer of two or more than) in a horizontal direction, and at least m times (m: integer of two or more than) in a vertical direction according to the resolution of the printing device; setting a dot group by connecting printing dots consecutive to one another based on one printing dot according to the resolution of the printing device, with having a margin in at least one direction of the horizontal and the vertical directions; and forming dot group in the corresponding sub-region according to digital data.

[47] Here, the method for forming image data including digital data may be implemented as an executable computer program, and the computer program may be stored in a storage medium such as a compact disc (CD).

[48] Forming and Printing Image Data

[49] As shown in FIG. 4, image data including sound sources list is divided into a plurality of image regions (CS) according to a resolution (1200 DPI) of a printing device. Here, the image data may include image data having characters such as sound sources list, pictures, diagrams, and letters to be printed on a printed material, a song book and constituting background; and sub-image data not having characters such as sound sources list, pictures, diagrams, and letters to be printed, but having only a pattern of dot groups in correspondence to the size of the printed material.

[50] As shown in FIG. 5, at least one of the image regions CS is divided nxm sub- regions SS by dividing the respective image regions at least n times (n: integer of two or more than) in a horizontal direction, and at least m times (m: integer of two or more than) in a vertical direction according to the resolution of the printing device.

[51] FIGS. 5 and 6 show one image region among the sound sources list divided into respective five sub-regions in horizontal and vertical directions, in which FIG. 5 shows two reference dot groups, and FIG. 6 shows maximum dot groups.

[52] In the sub-regions SS, dot groups 101, 102 are set. Each of the dot groups is formed by connecting a plurality of printing dots consecutive to one another based on one printing dot according to a resolution of a printing device, with having a margin in at least one direction of horizontal and vertical directions.

[53] In order to print the dot groups 101, 102 with an invisible state, a ratio between the dot groups 101, 102 and the margin inside the sub-regions SS have to be 1:1.5 or more than. In FIGS. 5 and 6, two dot groups and four margins are implemented in a horizontal direction.

[54] That is, the dot groups 101, 102 are configured as two or more consecutive dots in at least one direction of horizontal and vertical directions, and the margin is configured as three or more consecutive dots in at least one direction of horizontal and vertical directions.

[55] The image region CS may be recognized separately from its adjacent image region

CS by placing a blank space between the image region CS and its adjacent image region CS.

[56] Accordingly, at least one of the dot groups 101, 102 may be set as a reference dot group 101. The reference dot group 101 may be configured to have a different shape from the other dot group 102.

[57] That is, the reference dot group 101 may be formed in upset 'L' shape, and the other dot group 102 may be formed in upright 'L' shape. The dot groups may be formed in various shapes so as to correspond digital data to their various shapes.

[58] The dot group may be formed in an outline manner according to a printing method, and may have its inside filled or empty.

[59] Referring to FIGS. 7 and 8, the lowest and the left side of the image region CS may be further provided with a sub-region NCS for displaying NULL in digital data. [60] The image data forms dot groups 102 in corresponding sub-regions SS among the sub-regions SS of the image region CS according to digital data to be included.

[61] FIGS. 7 to 11 respectively show one example for forming dot groups in sub-regions

(CS) according to each bit of digital data.

[62] More concretely, FIG. 7 displays digital data of OOOOOOOO', FIG. 8 displays digital data of ¹OOOOOOOl¹, FIG. 9 displays digital data of OOOOOOlO', FIG. 10 displays digital data of OOOOOOl 1', FIG. 11 displays digital data of OOOOOlOO', and FIG. 12 displays 'NULL', each represented in '0' or T.

[63] As shown in FIG. 13, the image region CS having digital data corresponding to the sound source may be repeatedly formed on a certain region of a printed material 1 so as to be easily recognized by the apparatus 100 for selecting song. Here, the sub- regions SS inside each image region CS are recognized by the reference dot group 101. Particularly, as shown in FIG. 4, the digital data corresponding to the respective sound sources may be overlapped and printed on the respective sound source in the sound sources list or on the adjacent region, etc.

[64] In FIG. 13, a dotted- line grid is a line shown just for convenience, but is not substantially printed. However, the grid may be printed for a reference about each dot group. In other Figures rather than FIG. 10, the dotted-line shown just for convenience may be printed for a reference about each dot group.

[65] As shown in FIG. 13, image data including digital data used when printing sound sources list 11 may include image data having characters such as pictures, diagrams, and letters to be printed on a printed material 10 printed with the sound sources list 11 and constituting background; and sub-image data not having image to be printed, characters such as pictures, diagrams, and letters to be printed, but having only a pattern of dot groups in correspondence to the size of the printed material 10.

[66] Here, the sub-image data including digital data may be synthesized with the image data having characters thus to be together outputted, and may be individually outputted after the image data having characters is firstly outputted. Here, the sub-image data may be synthesized with the image data in various formats such as PDF file, BMP file, etc. Regardless of the kind of formats, the sub-image data has to be printed with using carbon-contained printing ink among generally used printing ink.

[67] In the case of general printing ink having basic four colors,red, blue, and yellow ink do not contain carbon, but only black ink contains carbon.

[68] Once the red, blue, and yellow are mixed to one another with the same ratio, black is implemented. In the present invention, the image data and the sub-image data may be separately printed from each other by utilizing the characteristic of the colors.

[69] When a plurality of colors are to be printed, each ink has to be printed in a certain order. Firstly, black obtained by mixing red, blue, and yellow colors and not containing carbon is used. Lastly, carbon-contained black is used to print the sub-image data having a pattern of dot groups combined to one another.

[70] It is most preferable to print the sub-image data with 4% of concentration. When a printing concentration is higher (more than 5%), other colors may be influenced. On the contrary, when the printing concentration is lower (less than 3%), ink is not evenly distributed resulting that the sub-image data may not be well recognized by an image recognizing device.

[71] When carbon-contained printing ink is used, the image may be precisely recognized by using an infrared Light Emitting Device(LED).

[72] Selecting a song

[73] A user selects a desired sound source in the sound sources list 11 printed in the printed material 10, a song book.

[74] Herein, the user uses the apparatus 100 according to the present invention, selects one of the sound source in the sound sources list 11 printed in the printed material 10 and positions the apparatus 100 on the selected sound source.

[75] Here, the image acquiring device 111 composing the apparatus 100, using a camera, positions the camera on the selected sound source, and acquires an image regarding the digital data printed together with the sound source automatically or by a user's handling of the handling unit 130. Herein, the position of the apparatus 100 may differ according to the position of the digital indicating sound source printed in the song book.

[76] Meanwhile, since the digital data corresponding to the respective sound sources together with the sound sources list 11, the data processing unit 112 analyzes and decodes the image acquired by the image acquiring device 111.

[77] Meanwhile, the decoded digital data by the processing unit 112 is transferred to the sound source generation signal unit 120, the sound source generation signal unit 120 generates a signal to generate a sound source indicating the digital data to the sound generating device 200. Here the digital data is transferred to the sound generating device 200 through the various data processing procedures such as a number indicating the sound source.

[78] In addition, the sound generating device 200 may be implemented to automatically generate at least a part of the selected sound source when the apparatus 100 is positioned on each sound source in the sound sources list 11, and may be provided with additional auxiliary sound generating device generating a part of a starting part of the sound source, which make the user select a desired song by generating at least a part of the selected sound source.

[79] It will also be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention cover modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
