Hereinafter, embodiments related to a control method that can be implemented in the mobile terminal 100 configured as above will be described with reference to the accompanying drawings. It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

2 is a flowchart illustrating a control method of the mobile terminal 100 according to the first embodiment of the present invention.

First, the mobile terminal 100 is turned on, and the camera 121 application is executed. In this case, the camera 121 application displayed on the touch screen 151 may be selected, or the camera 121 application may be executed by a predetermined user gesture.

When the camera 121 application is executed, a preview image, which is an image obtained through the camera 121, may be displayed on the touch screen 151 (S210). Also, a recording button may be displayed on the touch screen 151.

Accordingly, when the record button is selected, the control unit 180 may record the preview image displayed on the touch screen 151 from the time when the record button is selected and store the preview image in the storage unit 170. [ If the recording button is not selected, the control unit 180 can display the preview image acquired through the camera 121 on the touch screen 151. [

Also, when the application of the camera 121 is executed, the microphone 122 can sense the sound around the mobile terminal 100. Accordingly, when the record button is selected, the control unit 180 may store the sound received by the microphone 122 in the storage unit 170 from the point in time when the record button is selected. If the recording button is not selected, the control unit 180 may not store the sound sensed by the microphone 122 in the storage unit 170. [ In particular, a plurality of microphones may be embedded in the mobile terminal 100, and sound may be sensed by a plurality of microphones.

Thereafter, the microphone 122 can sense a new sound (S220). The new sound may be a sound generated by the object displayed on the touch screen 151. Also, the new sound may be a sound in which an object not displayed on the touch screen 151 is newly generated. Here, the position of an object generating a new sound can be sensed by a plurality of microphones, which will be described with reference to FIG.

If a new sound is sensed by the microphone 122 (S220_Y), a preset image may be displayed in the area corresponding to the object generating the new sound of the touch screen 151 (S230).

Specifically, in a state in which the preview image is displayed on the touch screen 151, a new sound can be sensed. In this case, the control unit 180 can sense the position of the sound newly generated by the plurality of microphones, that is, the position of the new object. In particular, the controller 180 can determine whether the position of the new object is up, down, left, or right relative to the preview image.

Accordingly, the control unit 180 can display a predetermined image in an area of the preview image corresponding to the position of the new object. The type of the preset image will be described in detail in Fig.

The user can then switch the shooting direction of the camera 121 to the side where the displayed image is located to include the new object in the preview image. Or if the displayed image is selected, the new object may be automatically zoomed out to be included in the preview image.

According to the operation of the mobile terminal 100, since the user can easily photograph the camera 121, the user's convenience can be improved.

Hereinafter, the operation of the mobile terminal 100 will be described in detail.

3 is a diagram for explaining a concept of sensing a distance to a sound source by two microphones. In this figure, a method of sensing or determining the position of an object generating a sound source, that is, a sound, by means of two microphones will be described.

Referring to FIG. 3, a sound is generated in the object " A ", which can be transmitted to the first microphone 122-1 and the second microphone 122-2 built in the mobile terminal 100. [ Here, the distance L1 between the "A" object and the first microphone 122-1 and the distance L2 between the "A" object and the second microphone 122-2 may be different from each other. The time at which the sound of the " A " object reaches the first microphone 122-1 and the time at which the sound of the " A " object arrive at the second microphone 122-2 may be different from each other. That is, the time when the new sound is sensed by the first microphone 122-1 may be different from the time when the new sound is sensed by the second microphone 122-2.

Accordingly, the controller 180 can determine that the distance L between the object A and the mobile terminal 100 is an average value of the first distance L1 and the second distance L2. In addition, the sound generated by the " A " object first arrives at the first microphone 122-1 as compared with the second microphone 122-2, It can be determined that the first microphone 122-1 is positioned in the direction in which the first microphone 122-1 is located.

On the other hand, even when an object other than the " A " object generates a new sound, the position of the object can be sensed by the method according to the above description.

4 is a diagram for explaining a layout of a microphone 122 built in the mobile terminal 100 according to the first embodiment of the present invention.

As shown in FIG. 4 (a), a plurality of microphones may be embedded in the upper side and the lower side of the mobile terminal 100, respectively. This arrangement is also a widely adopted approach.

However, the manner in which a plurality of microphones are arranged is not limited to FIG. 4 (a) and may be arranged as shown in FIG. 4 (b). That is, the first microphone 122-1 and the second microphone 122-2 are respectively installed on the upper side and the lower side of the mobile terminal 100, and the third microphone 122-3 and the fourth microphone 122-4, May be embedded in the left and right sides of the mobile terminal 100, respectively. According to this arrangement, it is possible to more accurately determine the position of the object generating the sound.

5 to 6 show an example of the operation of the mobile terminal 100 according to the first embodiment of the present invention. Hereinafter, the operation of the mobile terminal 100 according to the first embodiment will be described in detail, and a description of a part overlapping with the above description will be omitted.

5, the mobile terminal 100 executes the application of the camera 121, and the object obtained through the camera 121 on the touch screen 151 may be displayed as a preview image. Here, the first object A included in the preview image is generating sound, and the microphone 122 may sense the first sound generated by the first object A. Meanwhile, the first sound generated by the first object A may be sensed by one microphone 122, or may be sensed by a plurality of microphones.

6, the second object B, which is not included in the preview image, generates a new sound, and the microphone 122 senses a second sound that the second object B newly generates . Here, the second sound may be sensed by a plurality of microphones, and the controller 180 may determine the position of the second object B using a plurality of microphones as described above.

6, since the second object B that generates the second sound is not included in the preview image, the controller 180 controls the touch screen 151 corresponding to the position of the second object B The predetermined image 130 can be displayed in the area of the predetermined area.

Here, the preset image 130 may be various gradation, text, GUI (Graphic User Interface), etc. Hereinafter, the icon 130 will be used. However, the scope of the rights can not be reduced or limited by these terms, and may mean various images other than the icon 130.

The icon 130 is displayed in the area of the touch screen 151 corresponding to the position of the second object B so that the user can easily determine the position of the object generating the new sound. Therefore, the user can change the photographing direction of the camera 121 or adjust the photographing magnification so as to photograph an object generating a new sound. Details of this will be described in detail in FIG. 9 to FIG.

Therefore, according to the first embodiment of the present invention, the user's convenience in photographing can be improved.

7 to 8 are various examples of the icon 130 displayed on the mobile terminal 100 according to the first embodiment of the present invention. Hereinafter, various examples of the predetermined image 130 or icon 130 will be described.

Referring to FIG. 7 (a), a graphic object may be displayed in an area corresponding to a position of a second object B among the touch screen 151. In this case, the figure may be not only a polygon having various shapes such as a rectangle, a circle, an ellipse, a diamond, a trapezoid, but also a three-dimensional figure. Also, colors may be combined and displayed on the graphics as described above, and may be displayed in combination with various animation effects.

As shown in Fig. 7 (b), the gradation effect may be combined and displayed on the graphic as described above.

In addition, a text indicating that a new sound is generated may be displayed, and the text and the graphic may be combined and displayed as shown in FIG. 7 (c).

Meanwhile, the icon 130 may be displayed at the approximate position of the second object B as described above, but may be displayed at a more accurate position. 7 (d), the icon 130 may be displayed in the upper right area of the touch screen 151, thereby indicating that the second object B is located in the corresponding area.

Meanwhile, when the user changes the photographing direction of the camera 121 by referring to the icon 130 displayed on the touch screen 151, the icon 130 may be changed accordingly. Hereinafter, the icon 130 shown in Fig. 7 (c) will be described.

8A, the user can switch the photographing direction of the camera 121 in the direction in which the second object B is located. The icon 130 may be changed as shown in FIG. 8B. When the second object B is displayed on the touch screen 151, the icon 130 is displayed as shown in FIG. 8 (c) Can disappear.

On the other hand, the above description can also be applied to the icon 130 shown in Fig. 7 (a). Accordingly, when the photographing direction of the camera 121 is switched in the direction in which the second object B is located, the displayed icon 130, that is, the width of the figure, can be gradually reduced. Or the saturation of the displayed color may decrease or increase.

On the other hand, the above description can also be applied to the icon 130 shown in Fig. 7 (b). Accordingly, when the photographing direction of the camera 121 is switched in the direction in which the second object B is located, the gradation of the displayed color can be variously changed.

On the other hand, the above description can also be applied to the icon 130 shown in Fig. 7 (d). Accordingly, when the photographing direction of the camera 121 is switched in the direction in which the second object B is located, the number of the displayed concentric circles may gradually decrease or increase.

9 to 10 are various examples of images displayed on the touch screen 151 of the mobile terminal 100 according to the first embodiment of the present invention.

The second object B can be included in the preview image by switching the photographing direction of the camera 121 in the direction of the second object B as described above, as shown in FIG.

On the other hand, if the icon 130 displayed on the touch screen 151 is selected, the control unit 180 may automatically include the second object B in the preview image by changing the shooting magnification of the camera 121 , Which is shown in Fig. That is, the controller 180 performs a zoom-out function with respect to the camera 121 to include an object that generates a new sound together with the existing object included in the preview image, that is, the second object B .

In the above description, the second object B not included in the preview image frame is included in the preview image. However, the present invention is not limited thereto.

For example, the preview image displayed by the execution of the camera 121 application includes a third object (not shown) that does not generate a sound, and a third object (not shown) may generate a new sound . In this case, the controller 180 may display the icon 130 on the area of the touch screen 151 on which the third object (not shown) is displayed. Therefore, the user can switch the photographing direction of the camera 121 to photograph the third object (not shown) which generates a new sound. Or the icon 130 is selected, the control unit 180 may zoom in on the third object by performing a zoom in function with respect to the camera 121. [

Meanwhile, the mobile terminal as described above may be implemented by various devices such as a black box or a CCTV.

11 to 13 show another example of the operation of the mobile terminal 100 according to the first embodiment of the present invention. Hereinafter, a case where an object generating a sound moves will be described.

Referring to Fig. 11, the object moves from point " A " to point " B ". Accordingly, the touch screen 151 can display an object moving from the point "A" to the point "B" as a preview image.

As shown in FIG. 12, the icon 130 on the touch screen 151 can also move from the "A" point to the "B" point. That is, the icon 130 is also moved corresponding to the movement of the object, so that it is possible to clearly notify the user that the object generating the sound is moving.

Therefore, as shown in FIG. 13, the user can cause the moving object to be displayed at the center of the preview image by switching the photographing direction of the camera 121. Or the icon 130 displayed on the touch screen 151 is selected, the control unit 180 may automatically change the shooting magnification of the camera 121 to include the moving object in the center of the preview image.

FIG. 14 is an example of a flowchart related to a control method of the mobile terminal 100 according to the second embodiment of the present invention. The control method of the mobile terminal 100 according to the second embodiment may be implemented in combination with the description of the control method of the mobile terminal 100 according to the first embodiment described above. Hereinafter, the description of the parts overlapping with the above description will be omitted.

When the recording application is executed, a recording screen corresponding thereto can be displayed on the touch screen 151 (S1410). In addition, a recording button can be displayed on the recording screen.

Accordingly, when the record button is selected, the control unit 180 may record the sound received by the microphone 122 from the time when the record button is selected and store the sound in the storage unit 170. [

Thereafter, the microphone 122 can sense a new sound (S1420). The new sound may be a sound that occurs after the point at which the record button was selected. Here, the position of an object generating a new sound can be sensed by a plurality of microphones, as described with reference to FIG.

If a new sound is sensed by the microphone 122 (S1420_Y), the predetermined image 130 may be displayed in an area corresponding to the object generating a new sound in the recording screen (S1430).

Specifically, in a state in which a recording screen is displayed on the touch screen 151, a new sound can be sensed. In this case, the control unit 180 can sense the position of the sound newly generated by the plurality of microphones, that is, the position of the new object. In particular, the controller 180 can determine whether the position of a new object is up, down, left, or right relative to the recording screen.

Accordingly, the controller 180 may display the predetermined image 130 or the icon 130 in the area of the recording screen corresponding to the position of the new object. The type of the icon 130 is the same as described with reference to FIG.

Thereafter, the user can switch the direction of the microphone 122 to the direction in which the object generating the new sound is located, so that the new sound can be clearly and clearly recorded. In addition, when the displayed icon 130 is selected, the new sound is amplified and stored in the storage unit 170, so that new sound can be clearly and clearly recorded.

When the record button is selected, the microphone 122 receives the sound generated around the mobile terminal 100, and the received sound can be stored in the storage unit 170. [ The recording screen after the recording button is selected is as shown in FIG. 16, and the sound in which the first object A is generated is being recorded.

Thereafter, the first object A and the second object B different from the first object A may newly generate a sound. In particular, the second object B may generate sound at a position different from the first object A. In this case, the icon 130 may be displayed in an area corresponding to the position of the second object B among the areas of the touch screen 151 as shown in FIG.

If the user wishes to perform recording based on the sound generated by the second object B, the direction of the microphone 122 is switched to the direction in which the second object B is located by referring to the displayed icon 130 , The mobile terminal 100 can be moved.

In addition, when the displayed icon 130 is selected, the first sound generated by the first object A or the second sound generated by the second object B is automatically adjusted and stored in the storage unit 170 May be stored. Hereinafter, a specific example will be described.

18 to 19 are various examples of the volume of each of a plurality of sound sources recorded according to the second embodiment of the present invention.

Referring to FIG. 18, the first sound is stored at 10 dB, and the second sound is not generated. When the displayed icon 130 is then selected as the second sound is generated, the first sound may be stored at the same 10 dB as the existing level, and the second sound may be stored at the same level as the level received by the microphone 122 Level, i.e., 6 dB.

Alternatively, the levels of the first sound and the second sound may be relatively adjusted and stored. 19, the first sound may be stored in a state of decreasing from 10 dB to 8 dB, and the second sound may be stored at 7 dB which is a level higher than 6 dB, which is the level received by the microphone 122 . However, the specific values of the sound levels shown above are merely illustrative.

The present invention described above can be embodied as computer readable codes on a medium on which a program is recorded. A computer readable medium includes any type of recording device in which data that can be read by a computer system is stored. Examples of the computer readable medium include a hard disk drive (HDD), a solid state disk (SSD), a silicon disk drive (SDD), a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, And may also be implemented in the form of a carrier wave (e.g., transmission over the Internet). The computer may also include a controller 180 of the terminal. The foregoing detailed description, therefore, should not be construed in a limiting sense in all respects and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
