Description:
BACKGROUND 
       [0001]    The present invention relates to a balance adjustment control method for sound/illumination devices and, more specifically, to a balance adjustment control method for sound/illumination devices to automatically adjust balance among devices by using a control terminal which adjusts output levels of sound or illumination in a performance area including a plurality of sound output devices or a plurality of illumination deices. 
         [0002]    In general, a stage control device serves to control various lighting and sound equipment, event equipment, or stage equipment installed on the stage of performance facilities and most of them have been controlled the stage equipment by using a console listed and installed by a large number switch devices. 
         [0003]    In the conventional stage control device, one control module is connected to a plurality of stage equipment so as to analyze the control data transmitted from the control module, so that it selects the stage device capable of controlling through the IP address etc. to be controlled. 
         [0004]    In such a stage control device, a sound technician or a lighting technician manually sets the balance value according to the stage status, so that the control module adjusts the balance of sound or lighting etc. or adjusts the balance of sound or lighting through a pre-set program. 
         [0005]    Thus, there is a problem in that it requires the technicians and high-priced programs related to the sound effect or the lighting effect in order that the audiences feel the three-dimensional sound or the lighting effect. 
         [0006]    In addition, the conventional stage control device has a problem in that it cannot adjust the balance between the stage devices through the existing program stored in the control module in consideration of the characteristics of the stage devices or the characteristics of the output result between each device. 
         [0007]    Since such a stage control device uses the high-prices equipment and programs for applying to the directing area having a karaoke accompaniment device or a home theater, there is a problem that it cannot be actually applied to the small directing area. 
         [0008]    Currently, with the development of a digital video system and a digital sound system, a home theater system is increasingly commercialized by the user&#39;s need to enjoy the three-dimensional surround sound, which is capable of experiencing at the theater, at home 
         [0009]    When it plays the stereo music, it is important to realize a three-dimensional effect of the sound. Besides, in the case of the home theater system, the viewer recognizes that the sound is generated from the image screen, so that the viewer can be immersed in the images. Accordingly, the localization for the image should be formed by controlling the location and the output of the speaker. In other words, it requires a combination of the sound of each speaker according to the images. 
         [0010]    In order to satisfy the condition of this home theater systems, a variety of speaker systems have been developed. Presently, a DOLBY-PRO-LOGIC system manufactured by a DOLBY Laboratories is generally commercialized. 
         [0011]    Various audio systems including the home theater systems are equipped with a center channel speaker, a woofer speaker, left/right speakers, and front left/right speakers so as to generate the surround sound effect. Thus, the balance of the intensity of the sound volume outputted from the left and right speakers is accurately adjusted around the listener, so that it can maximize the sound effects. 
         [0012]    However, in the balance adjustment method of the audio system according to the conventional art, the listener manually adjusts the sound volume output level of the left and right speakers by using his hearing. Accordingly, there is a problem in that the general listeners wanting in professional skills cannot finely adjust the sound balance. In particular, there is a problem in that the sound balance of the audio equipment cannot be exactly adjusted around the video equipment in the audio/video system. 
       SUMMARY OF THE INVENTION 
       [0013]    The present invention has been made in an effort to solve the problems of the conceptual description of the conventional art as described above, and an object of the present invention is to provide a balance adjustment control method for sound/illumination devices in that sample sound data or sample illumination data is transmitted to a performance area including various kinds of sound devices, sound output devices, and illumination devices, and then output data obtained by measuring output characteristics output from the devices is compared with the sample sound data or sample illumination data, to automatically adjust balance of each device. 
         [0014]    According to one aspect of the present invention so as to accomplish these objects, there is provided to a balance adjustment control method for sound/illumination devices, which is performed by a control terminal performing a sound or illumination adjustment function with respect to a performance area where sound/illumination devices including at least one device of a plurality of sound devices, a plurality of sound output devices, a plurality of sound input devices, and a plurality of illumination devices are installed, the method including the steps of: extracting at least one sample sound data or sample illumination data corresponding to the performance area on the basis of basic data related to the performance area, and transmitting the extracted sample sound data or sample illumination data to a control device which controls operations of the sound/illumination devices; performing, by the control terminal, at least one manner of a manner of inputting output sound output from a plurality of the sound output devices when the sample sound data is output through a plurality of the sound output devices by the control device, or a manner of inputting input illumination data obtained by measuring illumination output states of the illumination devices when the sample illumination data is output through a plurality of the illumination devices by the control device, such that input sound data for the output sound or input illumination data for the illumination output states is input; and performing, by the control terminal, at least one manner of a manner of comparing the input sound data with the sample sound data to generate a sound balance adjustment signal for each of the sound output devices and then transmitting the sound balance adjustment signal to the control device, or a manner of comparing the input illumination data with the sample illumination data to generate an illumination balance adjustment signal for each of the illumination devices and then transmitting the illumination balance adjustment signal to the control device.

         [0019]    In the step of generating the sound balance adjustment signal and the step of generating the illumination balance adjustment signal, the maximum output sound or the maximum output illumination intensity is restricted by reflecting restriction policy information about light pollution or noise pollution. 
         [0020]    In the step of generating the sound balance adjustment signal, noise in the performance area is measured in a state where there is no output of the sound/illumination devices, a type and magnitude of the measured noise are figured out, noise level information is calculated, and then the noise level information is reflected to generate the sound balance adjustment signal.

         [0029]    According to the balance adjustment control method of the present invention, the sample sound data or sample illumination data is transmitted to the performance area including various kinds of sound devices, sound output devices, and illumination devices by the control terminal, and then output data output from the devices is compared with the sample sound data or sample illumination data, so that it enables automatic execution of balance adjustment of each device, thereby making it unnecessary for a sound or illumination-related engineer to manually adjust the balance and enabling anyone to easily adjust the balance of sound or illumination using the control terminal. 
         [0030]    Moreover, according to the balance adjustment control method of the present invention, a plurality of control devices for controlling devices in a performance area is unnecessary and only one control device capable of communicating with the control terminal is used. Therefore, the present invention can lower the device failure rate and prevent overload.

         [0048]    The video output device  105  includes a home theater which outputs video or sound, a computer, a display device, and the like. A display screen of such a video output device  105  may be included in the illumination device, and a sound device including a speaker may be included in the sound output device. 
         [0049]    The control device  120  controls an operation of the sound/illumination device  100 , and includes communication means for performing communication with the control terminal  200 . Such a control device  120  allows sample sound data transmitted from the control terminal  200  to be output to the sound output device  102 , and allows the output level of the sound output device  102  or the illumination device  103  to be adjusted in accordance with a sound balance adjustment signal or an illumination balance adjustment signal transmitted from the control terminal  200 . 
         [0050]    Herein, the balance may mean characteristics which can be achieved by output delay time setting or magnitude setting of the output and input designated in consideration of correlation among devices in a plurality of sound input devices  104 , a plurality of sound output devices  102 , or a plurality of illumination devices  103 . In addition, the control device  120  can adjust output balance among a plurality of the sound output devices  102 , output balance among a plurality of the illumination devices  103 , and input balance among a plurality of the sound input devices  104 . 
         [0051]    In addition, the control device  120  may adjust the volume by correcting input sound levels of a plurality of the sound input devices  104  such as microphones in accordance with the balance adjustment signal of the control terminal  200 , or may adjust screen brightness or an output sound level of the video output device  105 . In addition, output times among devices may be adjusted by setting an output delay time of each device of the sound/illumination device  100 . 
         [0052]    The control terminal  200  can be connected to the control device  120  by wireless communication such as Wi-Fi and Ethernet. The control terminal  200  may be embodied by a mobile device, and may be a stage control device, a home theater, a karaoke accompaniment device, and a computer connected to a mobile device or other input devices by wire or wireless communication. 
         [0053]    The mobile device measures an output state of the illumination device  103  or the sound output device  102 , and transmits the measurement result to the control terminal  200 . If the mobile device is the control terminal  200  itself, the control terminal  200  generates an illumination balance adjustment signal or a sound balance adjustment signal on the basis of basic data for a performance area and may output the signal to the control device  120  or may output the signal to each illumination device  103  or sound output device  102 . 
         [0054]    In this case, the control terminal  200  can automatically perform a sound or illumination balance adjustment function by executing a balance adjustment program after installing the balance adjustment program providing a process to automatically perform the balance adjustment control of the sound/illumination device. The balance adjustment program may be updated periodically or temporarily with sample sound data or data necessary for the other balance adjustment by a program provider.

         [0058]      FIG. 2  is a block diagram illustrating a configuration of the control terminal illustrated in  FIG. 1 . 
         [0059]    Referring to  FIG. 2 , when the mobile device is embodied as the control terminal  200 , the control terminal  200  includes a key input unit  210 , a speaker  220 , a microphone  230 , a communication unit  240 , an illumination sensor  250 , a camera  260 , a position sensor  270 , a control unit  280 , and a storage unit  290 . 
         [0060]    To the key input unit  210 , basic data including size information of a performance area, opening information for inside/outside, device information, and audience information can be input. In this case, the performance area may be an indoor or outdoor stage, a home, a karaoke, and may be a place where various sound-related devices are installed. 
         [0061]    The speaker  220  outputs various kinds of sounds including sample sound data, and various kinds of sounds including output sound output from the sound output device  102  and the like can be input to the microphone  230 . 
         [0062]    The communication unit  240  can transmit and receive various signals through to and from the control device  120  by wireless communication. 
         [0063]    The illumination sensor  250  measures illumination intensity, and can measure a visual effect degree including the illumination intensity by using the camera  260  when the control terminal  200  is not provided with the illumination sensor. 
         [0064]    The position sensor  270  measures a distance from the illumination device  103 , the sound output device  102 , or the video output device  105 , and may use an ultrasonic sensor, an infrared sensor, or the like. 
         [0065]    The control unit  280  controls each of the speaker  220 , the microphone  230 , the communication unit  240 , the illumination sensor  250 , the camera  260 , the position sensor  270 , and the storage unit  290 , to perform a sample sound data search function, a balance adjustment signal generation and transmission function, a position or direction calculation function, a position control signal generation and transmission function, and the like. 
         [0066]    The storage unit  290  stores sample sound data about the sound device  101  including various instruments or human voice for each of man, woman, old, and young in a lookup table form, stores sample illumination data about each of various illumination devices in a lookup table form, stores basic data about the performance area, and stores various kinds of data necessary for balance adjustment. 
         [0067]      FIG. 3  is a flow chart illustrating the balance adjustment control method for sound/illumination devices according to an embodiment of the invention. 
         [0068]    Referring to  FIG. 3 , according to the balance adjustment control method for sound/illumination devices, when the control terminal  200  is embodied by a mobile device, the control terminal  200  installs a balance adjustment program providing a process to automatically perform a balance adjustment control of the sound/illumination device  100 , stores a lookup table for the sample sound data about human voice and the sound device  101  in the storage unit  290  by the balance adjustment program, and stores a lookup table for the sample illumination data for each of various illumination devices  103 . 
         [0069]    A user inputs basic data about the performance area such as a room in which a home theater is installed, a performance stage, and a karaoke, to the control terminal  200 . The control terminal  200  searches at least one sample sound data and sample illumination data suitable for the performance area in the lookup table considering the sound/illumination device  100  disposed in the performance area, the size of the performance area, an opening/closing degree of the performance area, the number of audiences, available power magnitude, stage regulation, and the like on the basis of the basic data. 
         [0070]    First, the control terminal  200  transmits the searched sample sound data to the control device  120 , and the control device  120  allows the sample sound data to be output from the sound device  101  such as the electronic instrument and the speaker or the sound output device  102 . In a case of transmitting a plurality of sample sound data to the control device  120 , the control terminal  200  sequentially transmits the sample sound data at a predetermined time interval, thereby adjusting balance in a state where a mixing phenomenon or a noise phenomenon among the data is minimized. In addition, it is possible to adjust the balance considering mutual output characteristics among devices by transmitting the sample sound data together. 
         [0071]    The control terminal  200  repeatedly performs the sound balance adjustment function for each sound output device  102  to adjust the optimal output balance among the sound output devices  102 . 
         [0072]    The control terminal  200  receives the output sound output from the sound device  101  or the sound output device  102 , through the microphone  230  of the control terminal  200 , compares the input sound data for the output sound input in such a manner with the sample sound data to generate a sound balance adjustment signal to which a difference between output sound and standard sound is reflected, and transmits the signal to the control device  120  or transmits the signal to each sound device  101  or each sound output device  102 . 
         [0073]    For example, the control terminal  200  detect a output sound level output from the speaker in the performance area through the microphone  230 , and can generate and output the sound balance adjustment signal to adjust the volume of the speaker to the optimal state while comparing such a detected output sound level with the standard sound level. When a plurality of speakers are disposed in the performance area, the sound balance adjustment signal may perform adjustment of raising overall the output sound level by turning on at least one speaker or lowering overall the output sound level by turning off at least one speaker. 
         [0074]    In this case, when the control terminal  200  transmits the sound balance adjustment signal to each sound device  101  or each sound output device  102 , each sound device  101  or each sound output device  102  includes a communication function. 
         [0075]    For example, when the performance area is an indoor concert stage, and when the size of the indoor concert stage, the number of acceptable audiences, device information, singer information, and the like are input, the control terminal  200  searches sample sound data for each device, and searches sample sound data of human voice considering sex, age, and the like of the singer. 
         [0076]    Herein, the device information stored in the control terminal  200  includes at least one piece of information of a plurality of the sound output devices  102  and a plurality of the sound input devices  103 . The device information stored in the control terminal  200  can advantageously act in performing more precise balance adjustment by the control terminal  200  as detailed information such as the number of devices, input and output characteristics, and information about position is further accompanied. 
         [0077]    In addition, the device information may include information such as the kind and number of speakers, the kind and number of microphones, and the kind and number of accompaniment devices. 
         [0078]    The control terminal  200  sequentially transmits the searched sample sound data to the control device  120 , and the control device  120  allows each speaker or accompaniment device to output the sample sound data. The control terminal  200  inputs the output sound output from each speaker or accompaniment device, and then compares the output sound with the sample sound data to generate a sound balance adjustment signal. 
         [0079]    In other words, the control terminal  200  generates the sound balance adjustment signal to lower the sound level when the output sound is larger than the sample sound data, and generates the sound balance adjustment signal to raise the sound level when the output sound is smaller than the sample sound data. 
         [0080]    If a plurality of speakers is disposed in the performance area, the control terminal  200  generates the sound balance adjustment signal for each speaker to perform individual balance adjustment of each speaker. 
         [0081]    In addition, the control terminal  200  acquires a measurement time of the output sound after transmitting the sample sound, compares a difference of measurement times of the output sound among the sound output devices  102 , and designates an output delay time of each sound output device  102 , thereby performing the balance adjustment. 
         [0082]    Meanwhile, the control terminal  200  can restrict the maximum output sound by reflecting restriction policy information about noise pollution. In addition, the control terminal  200  measures noise in the performance area in a state where there is no output of all the sound device  101  and sound output device  102  in the performance area, figures out the type and magnitude of the measured noise, calculates noise level information, and can generate the sound balance adjustment signal by reflecting the noise level information. 
         [0083]    In addition, the control terminal  200  measures an interference degree according to the sound output among a plurality of the sound output devices  102 , and can generate the sound balance adjustment signal for adjusting the output sound level of each sound output device  102  by reflecting the measured interference information. 
         [0084]    Overall, the control terminal  200  sums the noise level information and the interference information to the output sound for the sample sound data of the sound output device  102 , compares the sum with the sample sound data, and can generate the optimal sound balance adjustment signal within the restriction information of the maximum output sound. 
         [0085]    Meanwhile, the control terminal  200  finds the sample illumination data suitable for the illumination device in the performance area on the basis of the basic data, and transmits the sample illumination data to the control device  120 , and the control device  120  controls the illumination device  103  to output the illumination state corresponding to the sample illumination data. 
         [0086]    Herein, the device information stored in the control terminal  200  includes information about a plurality of the illumination devices  103 . The device information stored in the control terminal  200  can advantageously act in performing more precise balance adjustment by the control terminal  200  as detailed information such as the number of illumination devices  103 , illumination output characteristics, and information about position is further accompanied. 
         [0087]    The control terminal  200  measures an illumination output state of the illumination device  103  by using the illumination sensor  250  or the camera  260 , compares the sample illumination data with the input illumination data in the measured illumination output state, generates an illumination balance adjustment signal to adjust the output level of each illumination device  103  to be raised or lowered in accordance with a difference value between two illumination intensities, and transmits the illumination balance adjustment signal to the control device  120  or each illumination device  103 . 
         [0088]    In the illumination device  103 , illumination output states such as a signal value of illumination, an intensity value, an output signal form, an operation time difference, a color, and blinking can be adjusted by the illumination balance adjustment signal. 
         [0089]    Meanwhile, the control terminal  200  can restrict the maximum output illumination intensity by reflecting restriction policy information about light pollution, measures ambient indirect illumination or brightness information in a state where the illumination devices  103  in the performance area are turned off, and the measured indirect illumination or brightness information is reflected, and can generate an illumination balance adjustment signal for adjusting the output level of each illumination device  103 . 
         [0090]    A balance adjustment control method for sound/illumination devices according to another embodiment of the invention can perform an operation of correcting input sound for a plurality of sound input devices  104  such as microphones in the control terminal  200 . 
         [0091]    In other words, the control terminal  200  transmits a sound source input signal to the control device  120  in order to receive a sound source of the sound input device  104 , and the control device  120  receives the sound source input signal and allows the sound source to be output for each sound input device  104 . In this case, the sound source input signal may be sample sound data, and specific sound data. 
         [0092]    The control terminal  200  inputs the sound source output for each sound input device  104 , compares difference between the sound source input signal and the sound, then generates an input sound correction signal for lowering or raising the input sound level of the sound input device  104 , and transmits the input sound correction signal to the control device  120 . 
         [0093]    Referring to  FIG. 1  again, in the balance adjustment control method for sound/illumination devices according to another embodiment of the invention, the sound output device  102  is provided with first rotation means  111 , and the illumination device  103  is provided with second rotation means  112 . The first rotation means  111  and the second rotation means  112  may be configured by step motors or the like, and rotate the sound output device  102  and the illumination device  103  within a predetermined angle range. 
         [0094]    In this case, the sound output device  102  may be a speaker, and the first rotation means  111  is installed for each speaker. In addition, the illumination device  103  may be a stage lighting fixture, a LED lamp, or the like, and the second rotation means  112  is installed in a frame fixing each lighting fixture and the like. 
         [0095]    The control terminal  200  calculates distance and direction information of the sound output device  102  and the illumination device  103  through the position sensor  270 . The control terminal  200  generates a position control signal considering a sound orientation angle on the basis of the distance and direction information of each sound output device  102  and the sound balance adjustment signal, and transmits the position control signal to the control device  120 . 
         [0096]    The control device  120  receives the position control signal, analyzes the position control signal to calculate a rotation direction and a rotation angle of each sound output device  102 , then generates a rotation control signal including the rotation direction and rotation angle information, and transmits the rotation angle control signal to the first rotation means  111 . Then, the first rotation means  111  rotates the sound output device  102  in accordance with the set rotation direction and rotation angle. 
         [0097]    In addition, the control terminal  200  generates a position control signal considering directionality of illumination on the basis of the distance and direction information of each illumination device  103  and the illumination balance adjustment signal, and transmits the position control signal to the control device  120 . 
         [0098]    The control device  120  receives the position control signal, analyzes the position control signal to calculate a rotation direction and a rotation angle of each illumination device  103 , then generates a rotation angle control signal including the rotation direction and rotation angle information, and transmits the rotation angle control signal to the second rotation means  112 , and the second rotation means  112  rotates the illumination device  103  in accordance with the set rotation direction and rotation angle. 
         [0099]    The balance adjustment control method for sound/illumination devices according to the embodiment of the invention can perform the sound balance or illumination balance adjustment function and similarly a balance adjustment function for the visual effect or sound effect of the video output device  105 , and a user can direct sound, illumination, or special effects in accordance with scenario stored in advance. 
         [0100]    The control terminal  200  is embodied by a mobile device, performs a function of adjusting the balance of the sound/illumination device  100 , and thus a separate input device is not necessary between the control terminal  200  and the control device  120 . However, when the control terminal  200  is any one device of the sound/illumination devices  100  or is embodied by a separated device, a mobile device or an input device capable of processing data about output sound or illumination output states is necessary between the control terminal  200  and the control device  120 . 
         [0101]    It is preferable that the control terminal  200  repeatedly performs the balance adjustment process for each device in order to achieve overall balance adjustment for a plurality of devices as targets of balance adjustment. 
         [0102]    While the present invention has been described with respect to the specific embodiments, it will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the present invention as defined in the following claims.
