`
`1. Field of the Invention
`The present invention relates to a system and method in a
`mobile communication terminal for recording audio and
`Video. In particular, a mobile terminal having a camera that
`records video and directs a microphone for recording a cor
`responding audio from its source is disclosed.
`2. Description of the Related Art
`A mobile communication system such as a mobile terminal
`is mounted with a camera, multimedia player, or the like to
`implement a variety of functions such as a multimedia com
`25
`munication, Voice communication, or short message service.
`A conventional mobile terminal has either an internally
`mounted camera or an externally mounted camera. The
`mobile terminal not only takes still images using the camera,
`but the terminal records video and audio as well.
`Referring to FIG. 1, a conventional mobile communication
`terminal is illustrated including a main body unit 10, keypad
`11, a microphone 12, a camera 14, a folder unit 15, a display
`unit 16, and a speaker 17. The main body unit 10 connects to
`a keypad 11 for inputting user commands. The microphone 12
`is mounted on the main body unit 10. The folder unit 15 is
`coupled to one end of the main body unit 10 utilizing a hinge
`unit 13. The folder unit 15 rotates, using the hinge unit 13,
`about the main body unit 17. The display unit 16 and the
`speaker 17 mount to the folder unit 15. The folder unit 15
`when opened has a keypad 11 facing a rear direction of the
`mobile terminal.
`The camera14 is mounted or disposed within the hinge unit
`13. An image, for example, of a person or an object may be
`recorded by the camera 14 in a front direction and a rear
`direction of the mobile terminal. The front direction of the
`mobile terminal is an opposite direction from that of the rear
`direction.
`The camera 14 rotates about the hinge unit 13 to face an
`object in a front direction of the mobile terminal. The mobile
`terminal records and outputs to the display unit 16 animage of
`the object located in a front direction of the mobile terminal.
`The image is not inverted.
`In another example, a user rotates the camera 14 about the
`hinge unit 13 directing the camera 14 toward an object posi
`tioned to a rear direction of the mobile terminal. The user
`records the image of the object. The image is outputted to the
`display unit 16. The image is vertically flipped. The user may
`flip the image from top to bottom to create a non-inverted
`image using a key or a keypad on the main body unit.
`When an object and an audio input for recording are
`located in a front direction of the mobile terminal, a volume of
`the audio input recorded through the microphone 12 located
`in the rear direction of the mobile terminal is undesirably low.
`A user may rotate the camera 14 in the direction of the
`microphone 12, which rotation results in the display unit 16
`

`
`40
`
`45
`

`facing the object. In this position, a user cannot observe the
`image of the object being recorded because the display unit 16
`faces the object.
`Other conventional mobile terminals have a display unit
`that rotates vertically as well as horizontally. However, these
`conventional mobile terminals have an spatially large hinge
`connection. This connection undesirably increases the size of
`the mobile terminal. Additionally users of the conventional
`mobile terminals having this large hinge connection have
`difficulty manipulating a keypad for inputting Volume selec
`tion, lightness control, and color control. This difficulty is
`caused by the keypad facing away from a user and toward an
`object, even though the display unit is rotated.
`Therefore, there is a need for a system that overcomes the
`above problems and provides advantages over other systems.
`

`
`DETAILED DESCRIPTION OF THE PREFERRED
`EMBODIMENTS
`
`The present invention relates to a system and method for
`positioning a microphone while recording video in a mobile
`communication system. The invention relates to positioning a
`microphone Substantially along the same direction as the
`Source of audio while recording video of objects or persons.
`Although the invention is illustrated with respect to a
`mobile terminal for recording audio corresponding to a video,
`it is contemplated that the invention may be utilized anywhere
`it is desired for transmitting, receiving, or processing audio
`and/or video signals from one location to another location.
`Reference will now be made in detail to the preferred embodi
`ments of the present invention, examples of which are illus
`trated in the accompanying drawings.
`Referring to FIG. 2A, a mobile terminal includes a body
`unit Such as a main body unit 20 rotationally connected to a
`folder unit 25. The rotational connection, in this example, is a
`hinge 23. The main body unit 20 includes a keypad 21 for
`inputting a user's command and a first microphone 22, for
`example a body microphone, for inputting a user's voice or
`output from an audio source.
`The folder unit 25 includes a display unit 26, a speaker 27
`and a second microphone unit 28, Such as a folder micro
`phone. The display unit 26 and the speaker 27, in this
`example, are mounted to the main body unit 20. The second
`microphone 28 is disposed or mounted to a surface opposite
`to that of the display unit 26 and the speaker 27. A side-key 29
`attaches to a side of the main body unit 20 for flipping from
`top to bottom an image outputted to the display unit 26.
`The second microphone receives an audio signal from an
`audio source positioned at a front of the mobile terminal.
`When recording a video, the first microphone 22 and/or the
`second microphone 28 are selectively driven corresponding
`to a direction that the camera 24 faces. A digital Switching unit

`controls the first microphone 22 and/or the second micro
`phone 28 depending on received signals defined by the loca
`tion of audio Sound.
`In one example, a Subject and an audio Source are posi
`tioned in a front direction of the mobile terminal. A user
`rotates the camera 24 about the hinge 23. The camera 24
`rotates to face the Subject. The camera 24 records and outputs
`an image (A) to the display unit 26. The display unit 26
`outputs the image (A). The image (A) is a non-inverted image
`substantially identical to that of the subject. A video function
`of the mobile terminal is set for operating, in this state, the
`camera 24, and the second microphone 28.
`Referring to FIG. 2B, a subject and an audio source are
`positioned in a rear direction of the mobile terminal corre
`sponding to that which the keypad 21 faces. The camera 24
`rotates to face the Subject. The camera 24 records and outputs
`an image (B) to the display unit 26. The display unit 26
`outputs an image (B) Substantially identical to an inverted
`image or a flipped image of the Subject. The flipped image is
`changed into the normal image by a userpressing the side-key
`29. A video function of the mobile terminal is set for output
`ting the video of the Subject through the camera 24, and
`operating the first microphone 22.
`In other words, a mobile terminal is switched to video
`mode and a video of a subject is recorded. The microphone
`positioned in a front direction of the mobile terminal initially
`receives an audio input. If a mobile terminal is switched to
`video mode, the second microphone 28 positioned at the front
`of the mobile communication terminal is operated, and the
`image outputted to the display unit 26.
`Referring to FIG. 3, a block diagram illustrates a camera
`unit 10, a digital switching unit 40, a control unit 20, and the
`microphone units 31, 32 of the present invention. The camera
`unit 10 is provided inputs for directional information of the
`camera. The control unit 20 outputs control signals for select
`ing the microphone units 31, 32 according to the directional
`information of the camera unit 10. The digital switching unit
`40 selectively connects to the first microphone unit 31 and the
`second microphone unit 32 in accordance with a control
`signal.
`The digital Switching unit 40 at one end connects to an
`inner Switch which operates a microphone output terminal
`(Mic +and Mic -) of the control unit 20. The digital switch
`ing unit 40 at the other end connects to the first microphone
`unit 31 and/or the second microphone unit 32. An inner
`switch is controlled, for example, by a General Purpose Input
`Output terminal (GPIO 0 and GPIO 1).
`Directional information, associated with controlling an
`image is received from the camera 24 and/or instructions to
`modify the image are received through the side-key 29 of a
`mobile terminal. Alternately, a pre-determined menu pre
`sented on the display unit 26 is used to control the images
`received from the camera 24. The image is displayed on the
`display unit 26. The control unit 20 outputs a control signal
`for controlling the digital switching unit 40. The control unit
`20 uses information from the camera unit 10 and the direc
`tional information associated with the camera.
`In one example, the control unit 20 detects the direction of
`the camera 24 being rotated to the rear and the side-key 29
`being pressed to change top and bottom of the image output
`ted to the display unit 26. The control unit 20 outputs a control
`signal connecting the inner Switch of a digital Switching unit
`40 to the first microphone 31. The digital switching unit 40
`operates the first microphone 22.
`If the direction of the camera 24 is rotated to record a video
`in a rear direction of a mobile terminal, and the side-key 29 is
`
`7
`
`

`

`5
`manipulated, the second microphone 28 installed at the folder
`unit 25 is automatically operated according to the basic set
`ting of the video mode.
`In another embodiment of the present invention, the
`method for selecting a microphone for receiving audio from
`Video comprises inputting directional information of a cam
`era 10 to a control unit 20, and outputting a control signal
`from a control unit 20 for selecting a first microphone unit 31
`and/or second microphone unit 32. The control signal
`includes the directional information provide by the camera
`unit 10.
`The method further comprises connecting selectively a
`digital switching unit 40 to the first microphone unit 31 or the
`second microphone unit 32 according to the control signal. In
`one alternative, the digital switching unit 40 selects both the
`first microphone unit 31 and second microphone unit 32.
`Software mounted at the control unit can include a method
`that the user can select the operation of the microphones by
`the hand according to circumstances as well as the method
`that recording of a Voice is optimized by automatically coor
`dinating the direction for recording video by the camera with
`the direction of the chosen microphone.
`This system provides a user pressing the side-key for flip
`ping from top to bottom the displayed image, a first micro
`phone or a second microphone along a direction correspond
`ing to the position of the Subject and the audio Source. Input
`commands to a keypad or a camera choose which microphone
`records audio corresponding to video. This keypad or camera
`provides the mobile terminal ability to control the micro
`phones positioned near to the audio Source receiving the
`audio.
`The mobile terminal provides a solution by mounting at
`least one microphone on an outer surface of the folder unit for
`having the microphones selectively operated corresponding
`to the direction of the camera.
`The mobile terminal of the present invention provides a
`solution for optimizing the volume received for a video
`through recording an audio using a microphone at a position
`corresponding to the direction of the camera and/or direction
`of the audio source.
