Title: Remote audio recording camera system

Description:
CROSS-REFERENCE TO RELATED APPLICATION(S) 
     This application claims priority from Korean Patent Application No. 10-2013-0110445, filed on Sep. 13, 2013, in the Korean Intellectual Property Office, the entire disclosure of which is incorporated herein by reference for all purposes. 
     BACKGROUND 
     1. Field 
     The following description relates to a camera system that provides remote audio recording by synthesizing speech data of users who are wearing Bluetooth headsets, and then transmitting the synthesized speech data to a Bluetooth camera to store the data in the camera. 
     2. Description of the Related Art 
     Generally, a camera is used to take photographs of a subject, but recently, beyond the function of taking still photographs, the camera includes various multimedia functions to film and store videos. 
     Photographs are usually taken by a user holding a camera in their hands, such that in a case where a user is at a distance from a subject while filming a video, a voice of the subject may not reach the camera, thus failing to be recorded. 
     In order to solve the problem, a Bluetooth camera with a Bluetooth module has been developed to receive and store speech from a subject wearing a Bluetooth microphone. However, in a conventional Bluetooth camera, speech of a subject is merely received and stored, but speech of a person filming a video is not transmitted to the subject, thereby leading to a difficulty in communication between a person filming a video and a subject to be filmed. Further, in a case where there is a plurality of subjects, there is a problem in that these subjects may not be able to communicate with each other. 
     SUMMARY 
     The present disclosure provides a remote audio recording camera system, in which users may communicate with each other even when they are at a distance from each other, and speech data of users may be synthesized to be stored in a Bluetooth camera. 
     In one general aspect, there is provided a remote audio recording camera system, which includes: at least one first Bluetooth headset configured to be worn by a first user; a second Bluetooth headset configured to be worn by a second user that communicates with the first user, and to synthesize speech data of the first user received by the first Bluetooth headset and speech data input from the second user by using a speech synthesizer to transmit the synthesized speech data; and a Bluetooth camera configured to include a speech storage that stores the synthesized speech data received from the second Bluetooth headset, and an image storage that stores captured images.

       FIG. 1  is a block diagram illustrating an example of a remote audio recording camera system according to an exemplary embodiment. The remote audio recording camera system  100  according to the exemplary embodiment enables users to communicate with each other even when they are far from each other, and synthesizes speech data of users to store the synthesized speech data in a camera. 
     As illustrated in  FIG. 1 , the remote audio recording camera system  100  includes a first Bluetooth headset  110 , a second Bluetooth headset  120 , and a Bluetooth camera  130 . 
     A first Bluetooth headset  110  is worn by a first user, and there may be one or more first Bluetooth headsets  110 . The first user wearing the first Bluetooth headset  110  may be a subject to be filmed. 
     A second Bluetooth headset  120  is worn by a second user that communicates with the first user, and synthesizes speech data of the first user received by the first Bluetooth headset  110  and speech data input from the second user by using a speech synthesizer  121  to transmit the synthesized speech data. 
     The second user wearing the second Bluetooth headset  120  may be a person holding the Bluetooth camera  130 , or may be a subject to be filmed. That is, the second user wearing the second Bluetooth headset  120  holds the Bluetooth camera  130  to film the first user, or may support the Bluetooth camera  130  on a support, such as a tripod, to remotely control the Bluetooth camera  140  through the second Bluetooth headset  120 , to be filmed along with the first user. 
     The second Bluetooth headset  120  includes a data transmitter that remotely controls operations of the Bluetooth camera  130 , so that the Bluetooth camera  130  may be operated remotely through the data transmitter even when users are far from the Bluetooth camera  130 . 
     The speech synthesizer  121  may include a digital signal processor (DSP). 
     The DSP is a microprocessor that not only removes unnecessary sounds but also corrects sound distortions, and synthesizes necessary information by performing processes, such as filtering, Fourier conversion, or the like. The DSP has a processing speed that is  40  times faster than a normal microprocessor. 
     The Bluetooth camera  130  includes a speech storage  131  that stores synthesized speech data received by the second Bluetooth headset  120 , and an image storage  132  that stores captured images. The Bluetooth camera  130  may be operated manually by the second user holding the camera and communicating with the first user, or may be supported on a support, such as a tripod, to be remotely controlled through the data transmitter built in the second Bluetooth headset  120 . 
     Once speech data transmitted and received between the first user and the second user are synthesized by the speech synthesizer  121  of the second Bluetooth headset  120 , to be transmitted to the Bluetooth camera  130 , the Bluetooth camera  130  stores the speech data synthesized by the speech synthesizer  121  in the speech storage  131 , so that the stored speech data may be played after filming to enable speech data of the first user and the second user to be checked afterwards. 
     As the Bluetooth camera  130  includes the image storage  132  that stores captured images, by operating the image storage  132  and the speech storage  131  together, filmed videos and speech data of the first user and the second user may be played together. 
       FIG. 2  is a block diagram illustrating a second Bluetooth headset in  FIG. 1 . 
     By referring to  FIGS. 1 and 2 , operations of the remote audio recording camera system  100  will be described below. 
     Once the second Bluetooth headset  120  receives speech data of the first user through a Bluetooth module, a controller receives speech data of the second user that has been received from a microphone to transmit speech data of the first user and speech data of the second user to the speech synthesizer  121 . Then, the speech synthesizer  121  synthesizes speech data of the first user and speech data of the second user through a digital signal processor, to transmit the synthesized speech data to the controller. 
     Subsequently, the controller transmits the synthesized speech data to the Bluetooth module, and the Bluetooth module transmits the data to the Bluetooth camera  130 . As the Bluetooth module includes a speech transmitter, speech data of the first user may be received to be heard through a speaker, and the synthesized speech data may be transmitted to the Bluetooth camera  130 . 
     Accordingly, the Bluetooth camera  130  may receive the synthesized speech data to store the data in the speech storage  131 , and by operating the image storage  132  and the speech storage  1431  together, the Bluetooth camera  130  may play a filmed video along with speech data of users. 
     As described above, the remote audio recording camera system  100  enables users to communicate with each other through Bluetooth headsets even when they are far from each other, thereby facilitating communication between users while filming. 
     In a conventional camera system, there is a problem in that speech of users may not be recorded in a camera. However, in the present disclosure, speech of users may be synthesized by the speech synthesizer  121  to be stored in the Bluetooth camera  130 , such that speech of users may be recorded remotely. 
     Further, the second Bluetooth headset  120  includes a data transmitter to remotely control the Bluetooth camera  130 , such that the Bluetooth camera  130  may be operated remotely through the data transmitter even when users are far from the Bluetooth camera  130  when filming. 
       FIG. 3  is a block diagram illustrating another example of the remote audio recording camera system in  FIG. 1 . 
     As illustrated in  FIG. 3 , a remote audio recording camera system  200  further includes a third Bluetooth headset  140  to be worn by a third user that communicates with the second user, and the second Bluetooth headset  120  synthesizes speech data of the third user received by the third Bluetooth headset  140  and the synthesized speech data described above by using a speech synthesizer, and transmits the data to the Bluetooth camera  130 . 
     The Bluetooth camera  130  receives and stores the synthesized speech data from the second Bluetooth headset  120 , such that speech data of all the first, second, and third users may be checked through the Bluetooth camera  130 . 
     As the third Bluetooth headset  140  that communicates with the second Bluetooth headset  120  is further included, direct communicate may be enabled between the second user and a plurality of users. That is, the second user may hear speech of the first user and the third user and may respond to them, thereby facilitating communication while filming. The second user wearing the second Bluetooth headset  120  may be a person that films a video, and the first user and the third user wearing the first Bluetooth headset  110  and the third Bluetooth headset  140  respectively may be subjects to be filmed. 
       FIG. 4  is a block diagram illustrating another example of the remote audio recording camera system in  FIG. 3 . 
     As illustrated in  FIG. 4 , a remote audio recording camera system  300  enables the first user wearing the first Bluetooth headset  110  and the third user wearing the third Bluetooth headset  140  to communicate with each other. 
     Speech data of the first user received by the first Bluetooth headset  110 , speech data of the third user received by the third Bluetooth headset  140 , and speech data input from the second user are synthesized by the speech synthesizer  121 , to be stored in the speech storage  131  of the Bluetooth camera  130 , thereby enabling speech data transmitted and received between the users to be checked after filming. 
     As described above, the first user and the third user may directly communicate with each other, such that there is no need for the second user to relay communications between the first user and the third user. 
       FIG. 5  is a block diagram illustrating another example of the remote audio recording camera system in  FIG. 4 . 
     As illustrated in  FIG. 5 , a remote audio recording camera system  400  may further include a speech synthesizer  141  of the third Bluetooth headset  140 , and a fourth Bluetooth headset  150  worn by a fourth user that communicates with the third user. 
     The third Bluetooth headset  130  synthesizes speech data of the fourth user received by the fourth Bluetooth headset  150  and speech data input from the third user by using the speech synthesizer  141 , and transmits the synthesized speech data to the second Bluetooth headset  120 . 
     Subsequently, the second Bluetooth headset  120  synthesizes speech data of the first user received from the first Bluetooth headset  110 , speech data input from the second user, and synthesized speech data of the third and fourth users received from the third Bluetooth headset  140  by using the speech synthesizer  121 , and transmits the synthesized speech data to the 
     Bluetooth camera  130 . 
     As the remote audio recording camera system  400  includes the speech synthesizer  141  and the fourth Bluetooth headset  150 , a greater number of users may communicate with each other, and their communications may be recorded and stored in the Bluetooth camera  130 , thereby enabling speech data to be checked after filming. 
     According to the present disclosure, even when users are far from each other, they may communicate with each other through a Bluetooth headset, thereby facilitating communication between users when filming. 
     Further, in a conventional camera system, there is a problem in that speech of users may not be recorded in a camera when the users are at a distance from the camera. However, the present disclosure synthesizes speech of users through a speech synthesizer, stores the synthesized speech in a speech storage of a Bluetooth camera, such that speech of users may be recorded remotely. 
     In addition, a third Bluetooth headset is further provided to enable a second user as a person who films videos to communicate with a first and a third users, thereby enabling direct communication between a person who is filming with a plurality of subjects to be filmed. 
     Moreover, a second Bluetooth headset is further provided with a data transmitter to remotely control operations of a Bluetooth camera, such that a Bluetooth camera may be operated remotely through the data transmitter even when the camera is at a distance from users while filming. 
     A number of examples have been described above. Nevertheless, it should be understood that various modifications may be made. For example, suitable results may be achieved if the described techniques are performed in a different order and/or if components in a described system, architecture, device, or circuit are combined in a different manner and/or replaced or supplemented by other components or their equivalents. Accordingly, other implementations are within the scope of the following claims.
