Hereinafter, embodiments related to a control method that can be implemented in the mobile terminal configured as above will be described with reference to the accompanying drawings.

For convenience of explanation, the mobile terminal described in the present invention does not necessarily include at least one of the components shown in FIG. Specifically, it is assumed that the mobile terminal according to the present invention includes a camera 121, a microphone 122, a display unit 151, a memory 160, and a control unit 180 among the components shown in FIG. 1 . At this time, the display unit 151 may be implemented as a touch screen to perform both output and input functions.

The mobile terminal according to the present invention has an object to remotely control the operation of the camera 121 with the user's voice by using the above configuration. Specifically, the mobile terminal according to the present invention may be configured to adjust a camera set value by a user's voice or to invoke a preset mode with a user's voice.

Hereinafter, the camera setting value is adjusted by the user's voice, and the preset mode is loaded by the user's voice to proceed with photographing in detail.

<Adjusting camera settings using user audio>

4 is a flowchart illustrating an operation of the mobile terminal according to the present invention. 4, when a user voice is input to the microphone 122 while the camera 121 is in the activated state (S401), the control unit 180 recognizes the user voice (S402) The camera setting value to be adjusted can be determined (S403).

The controller 180 controls the microphone 122 to be activated automatically when the camera 121 is activated or manually by the user's input to receive the user's voice through the microphone 122 while the camera 121 is in the activated state. .

For example, when a predetermined user input for activating the camera 121 is inputted, the controller 180 controls the microphone 122 to be automatically activated together with the camera 121, or after the camera 121 is activated It is possible to control the microphone 122 to be further activated by a predetermined user input. Refer to the illustration of FIG. 5 as to how the microphone 122 is manually activated.

5 is an exemplary diagram for explaining how a microphone is manually activated by user input. When a predetermined user input is input, the control unit 180 activates the camera 121 and controls the display unit 151 to display a photographing setting screen as in the example shown in FIG. The shooting setting screen may be for displaying a real-time preview image input to the camera 121 and adjusting various settings required for shooting.

5, the control unit 180 can control the on / off of the microphone 122 based on the user's input to the voice recognition function button 501. [0054] FIG. That is, when the user inputs the user input to the voice recognition function button 501 while the microphone 122 is in the inactive state, the control unit 180 can switch the microphone 122 to the active state, The control unit 180 may switch the microphone 122 to the inactive state when a user input is inputted to the voice recognition function button 501 in the voice recognition function button 501. [

If the user's voice is input to the microphone 122 after the microphone 122 is activated, the control unit 180 can recognize the user's voice and determine a camera setting value corresponding to the recognized voice.

Here, the camera setting value is set to at least one of zooming degree, exposure value (EV), sensitivity (International Standardization Organization, ISO), iris opening degree, shutter speed setting degree, One may be included.

For example, the user voice corresponding to the degree of zooming of the lens may be 'zoom in' or 'zoom out', and the user voice corresponding to the degree of exposure may have a meaning associated with brightness such as 'bright' or 'dark'. The user's voice corresponding to the degree of sensitivity may be 'high quality' or 'low quality', and the degree of opening of the iris may have a meaning associated with the opening and closing of the space such as 'open' or 'closed'. The degree of shutter speed setting may have a meaning associated with speed, such as &quot; fast &quot; or &quot; slow. &Quot;

The memory 160 may store a database for storing the matching relationship between the camera setting value and the user's voice and the controller 180 may determine the camera setting value corresponding to the user's voice from the database of the memory 160. [

For example, if the voice input by the user is recognized as 'zoom in', the controller 180 may determine the degree of zooming of the lens as a camera setting value to be adjusted.

However, the user voice corresponding to the camera setting value described above is merely an example for convenience of description, and does not limit the present invention. It goes without saying that, in addition to the above-described examples, various natural languages can correspond to each camera setting value.

If the camera setting value to be adjusted is determined, the controller 180 controls the camera setting value to be adjusted according to the meaning of the user voice (S404). If the user's voice is to raise the camera setting value, the camera setting value may be controlled to be upwardly directed toward the maximum level, and if the user's voice is to lower the camera setting value, the camera setting value may be controlled to be directed toward the maximum level .

In adjusting the camera set values based on the user's voice, the controller 180 may adjust the camera set values in stages. The controller 180 may adjust the camera setting value in consideration of the frequency of the user's voice, the strength of the user's voice (decibel, dB), and the degree of the user's voice sagging.

In addition, when the user's voice is input to raise the camera set value while the camera set value is set to the maximum level, or when the user's voice to lower the camera set value is input while the camera set value is set to the minimum level, The control unit 180 may control to display a guidance message for notifying that the camera setting value can not be increased or decreased any more.

The step of adjusting the camera setting values according to the characteristics of the user's voice will be described in detail with reference to the drawings described later.

6 is an exemplary diagram for explaining that the camera setting values are adjusted in stages according to user's voice. For convenience of explanation, the camera setting value to be adjusted in FIG. 6 is the degree of zooming of the camera 121, the degree of zooming of the camera 121 can be divided into five steps in total, and the degree of initial zooming is set to one level State.

When 'zoom in' is recognized through the user's voice while the degree of zooming is set to 1 level, the control unit 180 controls the degree of zooming of the camera 121 lens by one step as in the example shown in FIG. 6A . Although not shown, when 'zoom out' is recognized through the user's voice in a state where the degree of zooming is set to two levels, the control unit 180 can control the degree of zooming of the camera 121 to be down by one level .

The control unit 180 may adjust the camera setting value based on the frequency of the user's voice or the size of the user's voice.

For example, when the frequency f0 of the 'zoom in' uttered by the user is greater than the threshold frequency fth, the control unit 180 controls the zooming control so that the degree of zooming is immediately set to the maximum level as in the example shown in FIG. can do. That is, when the user has sufficiently 'zoomed in' in the high-frequency range, the controller 180 can control the degree of zooming to be set to the maximum level immediately. Although not shown, if the user utters 'zoom out' and the voicing frequency is greater than the threshold frequency, the controller 180 may control the degree of zooming to be set to the minimum level immediately.

On the contrary, if the zooming in or zooming out of the camera is smaller than the threshold frequency, the control unit 180 determines whether the degree of zooming of the camera 121 is one step upward or downward as in the example shown in FIG. One step down.

As another example, when the magnitude A0 of the 'zoom in' uttered by the user is larger than the threshold size Ath, the controller 180 controls the zooming control so that the degree of zooming is immediately set to the maximum level as in the example shown in FIG. can do. That is, when the user utters 'zoom in' with a loud enough sound, the control unit 180 can control the degree of zooming to be immediately set to the maximum level. Although not shown, if the user utters a 'zoom out' and the loudness size is larger than the critical size, the controller 180 may immediately control the degree of zooming to a minimum level.

On the contrary, if the user's zoom in or zoom out is smaller than the critical size, the control unit 180 determines whether the degree of zooming of the camera 121 is one step upward or downward, as in the example shown in FIG. 6A, One step down.

6D, when the 'zoom in' is recognized from the user's voice in the state where the zooming degree of the camera 121 lens is set to the maximum level, the control unit 180 determines the degree of zooming of the lens of the camera 121 Can be controlled so that the guide message for notifying that it can not be further raised can be displayed. If 'zoom out' is recognized from the user's voice while the degree of zooming of the camera 121 lens is set at the minimum level, the control unit 180 further reduces the degree of zooming of the camera 121 lens It is possible to control the display of the guidance message 601 for notifying the user of the failure.

The user can recognize that the degree of zooming of the camera lens 121 is set to the maximum level or the minimum level based on the guidance message 601 displayed on the display unit 151. [

In the example of Fig. 6, once the user's voice is input, the camera setting value is illustrated as being able to move up or down by one level, or to a maximum level or a minimum level at a time. In addition to the embodiment of FIG. 6, the controller 180 may control the camera setting value to gradually increase or decrease when the user's voice is continuously input without interruption, based on the slack of the user's voice. Reference will be made to the example of Fig. 7 as to whether the camera set value gradually increases or decreases.

7 is an exemplary diagram for explaining that the camera setting value is gradually increased when the user's voice is lengthened for a predetermined time. 6, it is assumed that the camera setting value to be adjusted is the degree of zooming of the camera 121, and that the degree of zooming of the camera 121 can be divided into five levels in total.

In the example of FIG. 7, the user's voice bar is expressed in units of time that the user drags the last syllable of the word &quot; zoom in. &Quot; In FIG. 7, it can be understood that the user continues to utter the last syllable 'from' t1 to t2 without stopping the utterance after uttering the word 'zoom in' for a time from 0s to t1.

7, when the word 'zoom in' is recognized from the user's voice, the control unit 180 controls the zooming degree to be raised by one step at the time point when the word 'zoom in' is recognized (t1 in FIG. 7) have. If the user drags the last syllable of 'zoom in', the control unit 180 determines whether the degree of zooming is incremented by one step (t2, t3, or t4 in FIG. 7) It can be controlled to be continuously raised.

If the user continuously sets the last syllable (t5 in FIG. 7) even after the degree of zooming is set to the maximum level or the user has set the zooming step to the maximum level, the control unit 180 notifies that the zooming level can not be further raised The guidance message 701 may be displayed.

Although not shown, when the word 'zoom out' is recognized from the user's voice, the control unit 180 controls the degree of zooming down by one level at the time when the word 'zoom out' is recognized, It is possible to control the degree of zooming to be continuously downward by one step according to the degree of ' If the user constantly sews the last syllable even after the degree of zooming is set to the minimum level, the control unit 180 may control to display a guidance message for notifying that the degree of zooming can not be further reduced.

In FIG. 7, the degree of zooming is continuously elevated according to the degree of the user's voice being raised after the level of zooming is raised by one step at the time t1 when the user's voice is recognized. However, the degree of zooming does not necessarily have to be increased at the time t1 when the user's voice is recognized. Unlike in FIG. 7, the control unit 180 may control the degree of zooming upward after the user slackens the last syllable without adjusting the degree of zooming at the time t1 when the user's voice is recognized.

Further, in FIG. 7, the intervals between t1 and t4 are exemplarily set to have the same unit time td, but the interval between t1 and t4 is not necessarily set to be the same. The control unit 180 may control the unit time from the next step to the next when the degree of zooming is upward or downward to be decreased. This will be described with reference to FIG.

8 is another exemplary diagram for explaining that the camera setting value is gradually increased when the user's voice is lengthened for a predetermined time. In Fig. 7, the time interval between t1 and t4 is maintained at td, while in Fig. 8, the time interval between t1 and t4 is set to td3 shorter than td1 and td2 shorter than td1, respectively. That is, as in the example shown in FIG. 8, the controller 180 may set the unit time to the next point in time to be increased each time the zooming information is upward. By setting the unit time to gradually decrease as shown in FIG. 8, it is possible to reduce the time required for the user to set the degree of zooming to the maximum level.

7 and 8 show that the guide messages 701 and 801 can be displayed when the slack of the user's voice continues for a predetermined time (exemplified by t0 in Fig. 7) while the degree of zooming is different from the maximum level . Unlike the example of FIGS. 7 and 8, the control unit 180 may automatically control to display the guidance message when the degree of zooming reaches the maximum level.

In FIGS. 6 to 8, the degree of zooming of the lens is exemplified as an example of camera setting values. However, this is merely an example for convenience of explanation, and will not limit the present invention. In addition to the camera set values illustrated in FIGS. 6 to 8, at least one of exposure level (EV), sensitivity (ISO) level, iris opening level, and shutter speed setting level of the camera 121 It is needless to say that the embodiments of FIGS.

Further, the guidance message described with reference to FIGS. 6 to 8 may be popped up on the display unit 151 in the form of a toast message. In this case, the guide message will automatically disappear from the screen after a predetermined time elapses.

Next, the operation of the mobile terminal capable of calling the preset mode by the user's voice will be described in detail.

<Load preset mode using user voice>

9 is a flowchart illustrating an operation of the mobile terminal according to the present invention. Referring to FIG. 9, in step S901, the preset mode setting step stores a set value in a memory 160 after setting a preset mode in which a keyword associated with a voice and a camera setting value are preset. The preset mode is used for presetting the quality of photographing using the camera 121. The camera preset values that can be preset through the preset mode include the exposure degree of the camera 121, sensitivity level, resolution level, white balance, A degree of aperture opening and a degree of shutter speed. The preset mode may include a keyword that can be mapped to a user voice. The keyword can be used as a tool for loading preset preset modes. The setting of the preset mode will be described in detail through the example of FIG.

10 is an exemplary view of a screen provided to a user for setting a preset mode. In the example shown in FIG. 10A, the degree of exposure of the camera 121 (corresponding to the brightness in FIG. 10A), resolution, white balance, and degree of sensitivity are exemplified by camera setting values that can be preset through the preset mode. The user can preset camera setting values such as exposure, resolution, white balance, and sensitivity through the example screen of FIG. 10A.

In the example of FIG. 10A, the speech recognition item may be for setting a keyword that can be mapped to a user voice. In the example of FIG. 10A, 'night' is set as a keyword.

When the setting of the preset mode is completed, the controller 180 may control to display a preset preset mode list as in the example shown in FIG. 10B. The control unit 180 may control the display of the preset preset mode list through keyword exposure in the preset mode as in the example shown in FIG. The user can delete or correct the preset mode based on the preset mode list shown in FIG. 10B, or add a new preset mode. The delete button 1001 of FIG. 10B is for deleting at least one preset preset mode, and the modification button 1003 of FIG. 10B may be for changing a detailed setting value of a predetermined preset mode. Further, it can be understood that the mode addition region 1005 of FIG. 10B is for setting a new preset mode.

If the user's voice is input (S902) after the setting of the preset mode is completed, the controller 180 recognizes the user's voice (S903) and extracts a preset mode having a keyword mapped to the recognized user's voice (S904) . Here, the activation of the microphone 122 for receiving the user voice may be automatically activated when the camera 121 is activated, or manually activated after the camera 121 is activated. A detailed description thereof has been given above with reference to FIG. 5, so that detailed description thereof will be omitted.

When the preset mode is extracted, the control unit 180 adjusts the camera setting value according to the preset value of the extracted preset mode (S905), and controls to automatically photograph the picture (S906). For example, if the user's voice is recognized as 'night' after the preset mode including the keyword 'night' is set as in the example of FIG. 10, the controller 180 controls the camera 121) You can control the exposure to 0EV, the resolution to 1024x768, the white balance to the automatic adjustment mode, the sensitivity to 400, and then the picture to be taken automatically. That is, it is possible to easily control the camera set value by controlling the camera set value according to the set value of the preset mode preset by the user's voice.

If a photograph is photographed using the preset mode, the control unit 180 may control the keyword of the preset mode to be tagged in the photographed image (S907). Specifically, the control unit 180 can control the keyword of the preset mode to be recorded in Exif (EXchangeable Image File format) of the shot image.

By tagging the keyword of the preset mode in the captured image, the control unit 180 can sort the captured image according to the preset mode, or extract and display only the captured image under a specific preset mode.

For example, FIG. 11 is an illustration for explaining extraction of a photographed image photographed under a specific preset mode.

In Fig. 11A, the shot image is illustrated as being sorted according to the album. 11A, when the user inputs a voice, the control unit 180 recognizes the user voice, and extracts the captured image of the keyword matching the recognized user voice to control the display of the extracted captured image list . For example, when the recognized user voice is 'night', the control unit 180 extracts a shot image in which 'night' is recorded as a keyword in Exif, and, as in the example shown in FIG. 11B, Can be controlled to be displayed.

By tagging the keyword of the preset mode in the captured image, the user can easily recall the desired captured image as in the example shown in Fig.

In the example of FIG. 9, when the user voice mapped to the keyword of the preset mode is recognized, the photographing is automatically started after adjusting the camera setting value according to the preset value of the preset mode. Alternatively, the start of photographing may be performed manually by waiting for user input. That is, the controller 180 may adjust the camera setting value according to the preset value of the preset mode, and then control the photographing when a photographing command is inputted by the user. Here, the shooting instruction may be input by the user's voice.

The embodiments described in Figs. 4 and 9 do not have to be separately implemented, but may be implemented through a single mobile terminal. In this case, the language used to adjust the camera settings may not be used as a keyword in the preset mode.

When the embodiment of FIGS. 4 and 9 is implemented through a single mobile terminal, the controller 180 determines whether the voice of the user is for adjusting the camera setting value or retrieving a preset preset mode keyword It is possible to control the operation of the rear mobile terminal.

According to one embodiment of the present invention, the above-described method (operation flow diagram) can be implemented as a code that can be read by a processor on a medium on which the program is recorded. Examples of the medium that can be read by the processor include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, etc., and may be implemented in the form of a carrier wave (e.g., transmission over the Internet) .

The above-described mobile terminal 100 is not limited in the configuration and method of the above-described embodiments, but the embodiments may be modified such that all or some of the embodiments are selectively combined .
