The present invention relates to a semi-period of the song, and more particularly, to a semi-period for selecting a song title by forming a code pattern in a song list of a song book and recognizing the code pattern of a wireless microphone.

In general, karaoke devices that are frequently used, the user selects a desired song from the memory pack and plays it back, while watching the lyrics displayed through the screen and sings along with the accompaniment sound heard through the speaker. Many people use it because they can easily practice the song by mixing it with the sound.

However, due to the hassle of many users, the karaoke device inputs the accompaniment of many songs into the memory, and if there is a selection of songs from the outside, the accompaniment of the corresponding song is output through the microphone. Wired and wireless microphones have been proposed and used to mix the input songs and output them to an external audio device wirelessly.

In addition, the karaoke device or the wired or wireless microphone should store information including accompaniment of as many songs as possible in order to make it widely available to a wide variety of people.

In addition, the built-in video song half-cycle allows users to sing along with the accompaniment sound while watching the screen on the TV by embedding lyrics data and background video signals in the wired and wireless microphones that contain accompaniment of many songs. .

In the conventional video song half-cycle, there is an inconvenient problem that a key operation is performed by finding a song number of a song book in which a song title is listed and inputting a number input from a keypad for numeric input provided for selection.

Accordingly, an object of the present invention is to provide a karaoke cycle capable of song selection using code recognition to select the song title by recognizing the code pattern formed in the song book to solve the above problems.

To achieve the above object, a song selection cycle using a code pattern of a song booklet in which a song title, a song number, a singer name, and a code pattern is formed for each song to achieve the above object includes a camera equipped with a lens, and the camera. A light source for irradiating a predetermined light toward the front of the light source, a control unit for recognizing a correct music piece through a code pattern photographed by the lens, a zoom control unit controlling a zoom function of the lens under control of the control unit, and And a code recognition unit for recognizing a code pattern corresponding to a song title formed in the song booklet, and a code pattern corresponding to a plurality of song songs, A memory for storing song songs and code pattern data recognized from the code recognition unit, and stored in the memory; Compared to the code pattern read out by the singing music piece data it is characterized in that it comprises a controller which controls to store the music piece selection of music for the songs.

FIG. 2 is a detailed configuration diagram of the code recognition unit 24 of FIG. 1.

The cord recognition unit 24 is installed at the end of the singing cycle period 100, the camera 11 equipped with a lens 17, and the light source 15 for irradiating predetermined light toward the front of the camera 11. ), A control unit 13 for recognizing the correct piece of music through the imaging information (code pattern) photographed by the lens 17, and a zoom control unit for controlling the zoom function of the lens under the control of the control unit 13 ( 14) and a light source controller 16 for turning on or off the light source under the control of the controller.

3 is an exemplary view of a song book 10 formed with a code pattern according to an embodiment of the present invention.

Song sequence number (No), song name, song number, singer name, chord pattern are formed.

4 is a control flowchart for selecting a piece of music according to an embodiment of the present invention.

1 to 4 will be described in detail the operation of the preferred embodiment of the present invention.

The user turns on the power to use the song cycle and selects the accompaniment function mode, and then searches for a song booklet 10 having a form as shown in FIG. 3 by using the numeric keys of the key input unit 22 for the desired song. Alternatively, the chord pattern formed on the song book 10 may be selected by bringing the chord recognition unit 24 into close proximity. The code recognition unit 24 includes a camera 11 having a lens 17, a light source control unit 16 for controlling the light source 15, and a signal processing unit 12 for processing code patterns captured by the camera 11. A control unit for controlling the zoom function of the lens 17 mounted on the camera 10, the light source control unit 16, the zoom control unit 14, and the signal processor 12. 13) a code pattern can be recognized. The code recognition unit 24 may recognize a code pattern by using the dot pattern reading unit disclosed in Korean Patent Laid-Open Publication No. 10-2004-0047819, and also the code by the code reading apparatus disclosed in Korean Patent Publication No. 1995-0020241. Recognize patterns.

When power is supplied, the controller 13 controls the light source controller 16 to turn on the light source 15. When the user selects a desired song song from the list of songs recorded in the song booklet 10 and brings the code recognition unit 24 closer to the code pattern formed in the song booklet 10, the camera 11 through the lens 17. ) Images the code patterns and applies them to the signal processor 12. The signal processor 12 converts the photographed code pattern into a digital signal and applies it to the controller 28 through the interface 26. At this time, the controller 28 receives the digital signal corresponding to the code pattern and compares it with the data stored in the code pattern stored in the memory 30 and stores information corresponding to the selected music piece in the music selection memory. When selecting several pieces of music, the above-described operation is repeatedly performed to select a piece of music.

An operation of selecting a piece of music formed in the song booklet by the above-described code pattern will be described in detail with reference to FIG. 4.

First, the user selects the accompaniment function mode through the key input unit 22 of the song accompaniment 100 having a song accompaniment function. Then, in step 101, the controller 28 checks whether the accompaniment function mode is selected and proceeds to step 102 if the accompaniment function mode is selected. In step 102, it is checked whether a numeric key is input from the key input unit 22. If the numeric key is input, the flow proceeds to step 105. In step 105, the controller 28 temporarily stores the input number and proceeds to step 106. In step 106, the controller 28 checks whether a reservation key is input from the key input unit 22, and returns to step 102 when the reservation key is not input, and proceeds to step 107 when the reservation key is input. In step 107, the controller 28 stores the music piece corresponding to the reserved number in the music selection memory area of the memory 30.

However, if the numeric key is not input in step 102, the controller 28 proceeds to step 103 and the controller 28 checks whether the code pattern recognition data is input from the code recognition unit 24, and then proceeds to step 104 when the code pattern recognition data is input. In step 104, the controller 28 reads the input code pattern and stores the song song corresponding to the code pattern in the music selection memory area of the memory 30.

In the case of selecting several pieces of music, when the user approaches the code recognition unit 24 to the code pattern of the desired piece of the song booklet 10 as shown in FIG. 3, the user repeatedly stores the desired pieces of music by repeatedly performing the above-described operation. .

In the present invention, one code pattern has been described as an example, but various modifications may be made by those skilled in the art without departing from the scope of the present invention by using various codes without departing from the scope of the present invention. And modifications are possible.

As described above, in the present invention, a code pattern corresponding to a song number is indicated on a song booklet in which a list of songs to be accompanied in a song cycle period is marked so that a song song is selected by recognizing a code pattern through a code recognition unit. There is an advantage that you can conveniently select a song song without pressing a button.
