Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 refers to a sensor that detects the presence or absence of an object approaching a predetermined detection surface or an object present in the vicinity without using a mechanical contact by using an electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in an inner region of the mobile terminal covered by the touch screen described above or near the touch screen.

Examples of the proximity sensor 141 include a transmission photoelectric sensor, a direct reflection photoelectric sensor, a mirror reflection photoelectric sensor, a high frequency oscillation proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is capacitive, the proximity sensor 141 may be configured to detect the proximity of the object by the change of the electric field according to the proximity of the conductive object. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, an action of allowing the object to be recognized without being in contact with the touch screen so that the object is located on the touch screen is referred to as a "proximity touch", and the touch The act of actually touching an object on a screen is called a "contact touch." The position at which the object is in close proximity touch on the touch screen means a position where the object is perpendicular to the touch screen when the object is in close proximity touch.

The touch sensor may be configured to detect a position, an area, a pressure at the touch, a capacitance at the touch, and the like, when the touch object applying the touch on the touch screen is touched on the touch sensor. Here, the touch object is an object applying a touch to the touch sensor and may be, for example, a finger, a touch pen or a stylus pen, a pointer, or the like.

As such, when there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and then transmits the corresponding data to the controller 180. As a result, the controller 180 can know which area of the display unit 151 is touched. Here, the touch controller may be a separate component from the controller 180 or may be the controller 180 itself.

Meanwhile, the controller 180 may perform different control or perform the same control according to the type of touch object that touches the touch screen (or a touch key provided in addition to the touch screen).

The ultrasonic sensor may recognize location information of a sensing object using ultrasonic waves. On the other hand, the controller 180 can calculate the position of the wave generation source through the information detected from the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the property that the light is much faster than the ultrasonic wave, that is, the time that the light reaches the optical sensor is much faster than the time when the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generation source may be calculated using a time difference from the time when the ultrasonic wave reaches the light as the reference signal.

On the other hand, the camera 121, which has been described as the configuration of the input unit 120, includes at least one of a camera sensor (eg, CCD, CMOS, etc.), a photo sensor (or an image sensor), and a laser sensor.

The camera 121 and the laser sensor may be combined with each other to detect a touch of a sensing object with respect to a 3D stereoscopic image. The photo sensor may be stacked on the display element, which is configured to scan the movement of the sensing object in proximity to the touch screen. More specifically, the photo sensor mounts a photo diode and a transistor (TR) in a row / column and scans contents mounted on the photo sensor by using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor calculates coordinates of the sensing object according to the amount of light change, and thus, the position information of the sensing object can be obtained.

The display unit 151 displays (outputs) information processed by the mobile terminal 100. For example, the display unit 151 may display execution screen information of an application program driven in the mobile terminal 100 or user interface (UI) and graphical user interface (GUI) information according to the execution screen information. .

In addition, the display unit 151 may be configured as a stereoscopic display unit for displaying a stereoscopic image.

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

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

The method for controlling a mobile terminal according to an embodiment of the present invention may be implemented in the mobile terminal 100 described with reference to FIG. 1. Hereinafter, a control method of a mobile terminal and an operation of the mobile terminal 100 for implementing the same will be described in detail with reference to the accompanying drawings.

Referring to FIG. 2, the controller 180 may recognize an object included in a preview image acquired through a camera or an event related to driving of the camera [S100].

When an input for driving the camera 121 is received at the mobile terminal 100, the controller 180 may execute a camera application. The preview image may be displayed on an execution screen of the camera application. The preview image may mean that image data acquired through the camera 121 is displayed on the touch screen 151 in real time.

The controller 180 can recognize an object included in the preview image. The controller 180 may identify the object included in the preview image by analyzing the preview image. The controller 180 may recognize whether the identified object matches a specific object by comparing the identified object with previously stored data. For example, when the image of the object identified in the preview image matches the image of person A stored in advance, the object may be recognized as person A.

According to one example, the analysis or comparison of the images may be performed using an artificial intelligence algorithm. At least one artificial intelligence algorithm may be stored in the memory 170. The AI algorithm may be implemented by one or a plurality of algorithms set to perform an optimal operation according to a specific condition in relation to photographing an image. Hereinafter, unless otherwise stated, an operation performed by the controller 180 may be performed using the artificial intelligence algorithm.

When the camera 121 is driven, the controller 180 may execute the artificial intelligence algorithm and analyze or compare images according to the determination of the artificial intelligence algorithm. However, as an example, the artificial intelligence algorithm may be executed regardless of the driving of the camera 121. In this case, the controller 180 may analyze and compare images by using an artificial intelligence algorithm executed when the camera 121 is driven.

The method of identifying an object in the image or recognizing the identified object is not limited to a specific method. If an object in the image can be identified and recognized, any image analysis method or image comparison method can be applied. In addition, if the analysis and comparison of the image can be performed by applying this method, the artificial intelligence algorithm is not limited to a specific algorithm.

The event related to the driving of the camera may include an event acquired at the moment of driving the camera 121 or while the camera 121 is being driven. For example, location information or time information of the mobile terminal 100 obtained at the moment when the camera 121 is driven may be included in the event. Alternatively, the event may include that a specific object appears in the preview image while the camera 121 is being driven. Alternatively, a specific voice input acquired while the camera 121 is being driven may be included in the event.

When the event is obtained, the controller 180 may recognize whether the event matches the specific event by comparing the previously stored data. For example, assume that a voice input corresponding to the name of a specific person A is obtained through the microphone 122. The controller 180 may compare whether data corresponding to the voice name is stored in the memory 170. When matching data is stored, the obtained event may be recognized as a specific stored event.

According to one example, the recognition of the event may be performed using the artificial intelligence algorithm. When the event is obtained, the controller 180 may execute the AI algorithm and determine whether the event is a previously stored event according to the determination of the AI algorithm.

Referring back to FIG. 2, the controller 180 may select a photographing mode corresponding to the recognized object or event from a plurality of photographing modes corresponding to a plurality of objects or a plurality of events stored in a database [S110]. .

The memory 170 may store data about a plurality of objects, a plurality of events, and a plurality of photographing modes respectively corresponding thereto. The photographing mode may mean a state in which the preview image is provided. For example, the capturing mode may include various capturing modes such as changing image attributes such as brightness and saturation to be applied to the preview image, and setting a reference for focusing in the preview image.

When the controller 180 recognizes a specific object or recognizes a specific event, the controller 180 may select a photographing mode corresponding to the recognized object or event among a plurality of photographing modes stored in the memory 170. For example, when a specific person is recognized in the preview image, a shooting mode that focuses on the recognized specific person may be selected.

According to an example, the selection of the photographing mode may be performed by the artificial intelligence algorithm. In this case, the artificial intelligence algorithm may select a shooting mode to be applied by referring to the information on the plurality of shooting modes. In addition, the AI algorithm acquires information on whether an image has been taken or a change in the shooting mode by the user according to the selected shooting mode, thereby modifying the setting information included in each shooting mode or for each shooting mode. You can update the importance.

Referring back to FIG. 2, the controller 180 can apply the selected shooting mode to the preview image and display it on the touch screen [S120].

The controller 180 may apply a setting value included in the selected photographing mode to the preview image. For example, it is assumed that a photographing mode for raising a brightness of an image to a predetermined value is set for a specific person A. In this case, when the person A is recognized in the preview image, the controller 180 may adjust and display the brightness of the preview image to the predetermined value.

Referring back to FIG. 2, the controller 180 can capture the displayed preview image [S130].

The user may check a preview image to which a shooting mode corresponding to a specific object or a specific event is applied. When the user applies an input for capturing an image, the controller 180 may capture and store the preview image displayed at the moment when the input is applied to the memory 170.

According to this, the user can check the preview image to which the optimal shooting mode is applied according to a specific object or a specific event only by driving the camera.

Hereinafter, a case of selecting and providing an optimal shooting mode according to a specific object or a specific event will be described in detail with reference to the accompanying drawings.

3 is a flowchart illustrating a method of applying a shooting mode according to voice input and object recognition according to an exemplary embodiment. 4 to 7 are views for explaining the application of the shooting mode according to the voice input and object recognition according to an embodiment of the present invention.

Referring to FIG. 3, the controller 180 may receive a voice input corresponding to a preset object [S200].

Referring to FIG. 4, it is illustrated that the user a tries to photograph a specific person b using the mobile terminal 100. When an input for driving the camera 121 is received at the mobile terminal 100, the controller 180 may execute a camera application. The camera application may be displayed as shown in FIG. 5.

The execution screen of the camera application may be displayed on the touch screen 151. According to an example, the preview image 10 acquired by the camera 121 may be displayed on the whole or one area of the execution screen. In the execution screen, a control area 1 for displaying items for changing the settings of the camera 121, a shooting button 2, a video shooting button 3, an end button 4, and thumbnails of recently photographed images 5), the general angle selection button 6 of the camera, the wide angle selection button 7 of the camera, and the like.

The user may make a predetermined voice to capture an image while the preview image is displayed. For example, as shown in FIG. 4, the name of the specific person may be spoken. However, this is merely an example and the present invention is not limited thereto. According to another example, the voice input may be set to a voice used to routinely draw attention of a subject. For example, the voice may be set as 'Look Here'. The controller 180 may receive the voice input through the microphone 122.

Referring back to FIG. 3, the controller 180 can recognize whether the preset object is included in the preview image [S210].

The controller 180 can recognize an object included in the preview image. Referring to FIG. 6, the controller 180 may identify the specific person b, which is an object included in the preview image, by analyzing the preview image. The controller 180 may compare whether there is previously stored data that matches the identified specific person b. That is, when the image of the identified person b is identical to the image of person b stored in advance, the object may be recognized as person b.

When the specific person b is recognized, the controller 180 may display the indicator 11 indicating that the focus is on the specific person b as shown in FIG. 6.

As described above, the analysis or comparison of the images may be performed using an artificial intelligence algorithm. The controller 180 may analyze or compare images according to the determination of the AI algorithm. In addition, the method of identifying an object in the image or recognizing the identified object is not limited to a specific method.

Referring back to FIG. 3, the controller 180 may apply the image property set for the preset object to the preview image [S220].

In the memory 170, shooting modes corresponding to specific objects may be set and stored. Values of image attributes corresponding to specific objects may be set and stored in the photographing mode. The image property may include effects such as brightness, saturation, exposure, color contrast, saturation, white balance, focus, and flash applied to the preview image.

For example, in response to the specific person b, a shooting mode for adjusting the brightness to a specific brightness and focusing on the specific person b may be set. In this case, the controller 180 may adjust the brightness of the preview image 10 displayed on the touch screen 151 to the predetermined specific brightness.

Referring back to FIG. 3, the controller 180 may select a photographing mode for adjusting a focus around the preset object [S230].

The controller 180 may adjust the focus around the specific person b according to the shooting mode. Referring to FIG. 7, the controller 180 may focus on the specific person b. In addition, according to an example, a zoom in operation may be performed based on the specific person b.

Thereafter, when a touch input is applied to the photographing button 2, the controller 180 may capture a preview image in a state in which a photographing mode in which brightness and focus are adjusted is applied.

According to this, when a specific object is included in the preview image, the user may capture the image by only making a specific voice. In addition, the user may conveniently be provided with a preview image adjusted to an image property value set to correspond to a specific object.

8 is a flowchart illustrating a method of applying a shooting mode according to weather information according to an embodiment of the present invention. 9 to 11 are diagrams for describing an application of a shooting mode according to weather information according to an exemplary embodiment.

Referring to FIG. 8, the controller 180 may receive a voice input corresponding to the weather [S300].

Referring to FIG. 9, it is illustrated that the user a photographs using the mobile terminal 100. The user may make a voice corresponding to the weather while the preview image 20 is displayed as shown in FIG. 10. For example, as shown in FIG. 9, the specific weather may be referred. However, this is merely an example and the present invention is not limited thereto. According to another example, the voice input may be set to voice related to weather. For example, it may be set as a voice such as 'weather effect applied'. The controller 180 may receive the voice input through the microphone 122.

Referring back to FIG. 8, the controller 180 may obtain weather information according to location information of the mobile terminal [S310].

When the voice input corresponding to the weather is received, the controller 180 may obtain location information of the mobile terminal 100 through the location information module 115. The controller 180 can obtain weather information on the location obtained on the network.

Referring back to FIG. 8, the controller 180 may select a photographing mode in which an image property corresponding to the acquired weather information is applied to the preview image [S320].

In the memory 170, shooting modes corresponding to specific weather information may be set and stored. Values of image attributes corresponding to specific weather may be set and stored in the photographing mode.

For example, it is assumed that a shooting mode for adjusting a color of a preview image to a tone of a specific color is stored in advance in response to the specific weather. In this case, as illustrated in FIG. 11, the controller 180 may adjust the preview image 21 displayed on the touch screen 151 to the tone of the specific color. However, this is merely an example and the present invention is not limited thereto. Shooting modes to which various image attributes are applied may be set according to each weather.

According to another example, when the voice input corresponding to the weather is a specific weather, the controller 180 may immediately select a shooting mode set to correspond to the specific weather. For example, when a voice input of 'snow falling' is received, the controller 180 may apply a shooting mode set in relation to snow to the preview image regardless of current weather information.

Thereafter, when a touch input is applied to the photographing button 2, the controller 180 may capture a preview image in a state in which a photographing mode for adjusting the tone of the specific color is applied.

According to this, the user can conveniently photograph the preview image provided with an effect suitable for the weather information according to the user's voice input.

12 is a flowchart of a method of applying a photographing mode according to a predetermined category, according to an exemplary embodiment. 13 to 15 are diagrams for describing an application of a shooting mode according to a predetermined category, according to an exemplary embodiment.

Referring to FIG. 12, the controller 180 may receive a voice input corresponding to a predetermined category [S400].

Referring to FIG. 13, it is illustrated that the user a photographs using the mobile terminal 100. The user may make a voice corresponding to a predetermined category while the preview image 30 is displayed as shown in FIG. 14. The categories may correspond to categories in which relevant information may be obtained through a network. For example, as shown in FIG. 13, a user may speak the title of the particular play.

However, this is merely an example and the present invention is not limited thereto. According to another example, the category may include various categories such as sports and performances. The controller 180 may receive the voice input through the microphone 122.

Again, referring to FIG. 12, the controller 180 may select a photographing mode in which a photo frame corresponding to the category is displayed on the preview image and taken together (S410).

The memory 170 may store a shooting mode for displaying a photo frame corresponding to a specific category. The photo frame may be configured using information corresponding to a specific category, and may be a frame in which information is displayed on the edge of the preview image. The photographing mode may be set to display the photo frame overlapping the preview image.

When the voice input corresponding to the category is received, the controller 180 may obtain information about the category through the wireless communication unit 110. For example, when receiving the title of the play 'sleep no more' by voice, the controller 180 may obtain an image or information related to the play on the network.

As illustrated in FIG. 15, the controller 180 may configure an image related to the play or time information on which the play is performed on the preview image 31 displayed on the touch screen 151 as a picture frame. The controller 180 can display the photo frame on the preview image 31 in a superimposed manner. As an example, the photo frame shown in FIG. 15 may be configured differently as necessary.

Thereafter, when a touch input is applied to the capturing button 2, the controller 180 may capture the photo frame and the preview image as a single image.

Accordingly, a preview image to which a photo frame corresponding to a category according to a voice input is automatically applied may be provided.

16 is a flowchart illustrating a method of applying a photographing mode of capturing a wide angle and a general angle together according to an embodiment of the present invention. 17 and 18 are diagrams for describing an example of applying a shooting mode of capturing a wide angle and a general angle according to an embodiment of the present invention.

Referring to FIG. 16, when the predetermined person is recognized in the preview image, the controller 180 may photograph the preview image at the wide angle [S500].

According to an example, the mobile terminal 100 may include a wide angle camera having a wide angle lens and a general angle camera having a general angle lens. In this case, the switching between the wide angle and the normal angle may be performed by switching between the wide angle camera and the normal angle camera. However, the present invention is not limited thereto, and any camera may be applied without limitation as long as wide angle and general angle shooting are possible.

The memory 170 may store a shooting mode corresponding to a case in which a predetermined person is recognized in the preview image and an event of adjusting the shooting angle of the camera 121 to the wide angle is recognized. The photographing mode may be set to re-capture a specific person at a general angle when a specific person is included when capturing a background image at a wide angle.

Referring to FIG. 17, a background image in which the photographing angle of the camera is adjusted to the wide angle is displayed as the preview image 40. The controller 180 can check whether the person is included in the preview image 40. It may be determined whether a specific person c included in the preview image 40 matches the predetermined person.

In order to capture a wide range of background images, a touch input may be applied to the photographing button 2 while the photographing angle is set to the wide angle. The controller 180 can capture the preview image 40 at a wide angle.

Again, referring to FIG. 16, the controller 180 may retake the preview image by adjusting the photographing angle of the camera to a general angle and focusing on the predetermined person [S510].

The controller 180 may adjust the photographing angle of the camera 121 to the general angle after the photographing is performed when the specific person c is the predetermined person as the reference for determining the photographing mode. As illustrated in FIG. 18, the controller 180 may display an indicator 41 indicating a range to be photographed at a general angle around the specific person c. The controller 180 may display the indicator 42 indicating that the focus is on the specific person c.

The controller 180 may further capture an image having a range of the indicator 41 at a general angle. In this case, the resolution of the further captured image may be set to be the same as the image captured at the wide angle. Accordingly, a total of two images, an image photographed at a wide angle and an image photographed at a general angle, may be stored.

Accordingly, by photographing a specific person at a general angle while photographing the background image at a wide angle, an image in which the specific person included in the background image is highlighted may be further photographed.

19 is a flowchart illustrating a method of applying a shooting mode of capturing an image when a specific person is recognized according to an embodiment of the present disclosure. 20 and 21 are diagrams for describing an application of a shooting mode of capturing an image when a specific person is recognized according to an embodiment of the present disclosure.

Referring to FIG. 19, the controller 180 may recognize the predetermined person in the preview image [S600].

The memory 170 may store a shooting mode in which the preview image is captured when a predetermined person is recognized in the preview image. Referring to FIG. 20, the mobile terminal 100 is fixed to the holder 200. The preview image 50 is displayed on the touch screen 151. Suppose a particular person d enters from outside the camera's shooting angle.

In FIG. 20, an indicator 51 indicating that the focus is on the specific person d is displayed. Since the specific person d is looking to the side, it is assumed that the controller 180 cannot recognize the specific person d yet. Thereafter, when the face of the specific person d faces the camera direction, the controller 180 may acquire a face area for recognizing the specific person d.

Referring to FIG. 21, a preview image 52 is shown in which a face of a specific person d faces in the camera direction. The controller 180 may determine whether a specific person d corresponds to a pre-stored person, which is a reference for determining the shooting mode.

Again, referring to FIG. 19, the controller 180 may capture the preview image [S610].

The controller 180 may capture the preview image 52 when the specific person d is the pre-stored person who is a reference for determining a shooting mode.

According to this, a natural image that does not care about a camera may be photographed automatically for a specific person.

22 is a flowchart illustrating a method of applying a shooting mode according to driving time and position information of a camera according to an exemplary embodiment. 23 and 24 are diagrams for describing an application of a shooting mode according to driving time and position information of a camera according to an exemplary embodiment.

Referring to FIG. 22, the controller 180 may acquire time and location information of the camera being driven [S700].

The memory 170 may store information about a shooting mode used according to the time and location information of the camera 121. For example, time and location information of a user photographing an image using the mobile terminal 100 may be stored in the memory 170. In this case, information on a shooting mode, such as an image property at the time of image shooting, may be stored together.

According to an example, the photographing mode may store the number of times of use according to a predetermined range of the time and the location. For example, when an image is taken in the same shooting mode in a region within a range from one pm to two pm, the number of shots may be accumulated and stored.

The controller 180 can obtain location information of the mobile terminal 100. Referring to FIG. 23, the controller 180 may display a screen 60 including 'golden gate bridge' which is location information of the mobile terminal 100. The current time information may be displayed on the screen 60.

In addition, an auto mode button, a manual mode button, a panorama mode button, etc. may be displayed on the right side of the area in which the time information of the screen 60 is displayed in order from the left side. When a touch input is applied to the auto mode button, the controller 180 may drive the camera 121 and acquire time information on which the camera is driven.

Referring back to FIG. 22, the controller 180 may select a photographing mode having the highest frequency of use at the time and location [S710].

The controller 180 may select a photographing mode most used at the current location and time based on the information on the photographing mode among the plurality of photographing modes stored in the memory 170. As illustrated in FIG. 24, the controller 180 may display the preview image 61 to which the selected shooting mode is applied on the touch screen 151.

Subsequently, when a touch input is applied to the photographing button 2, the controller 180 may capture a preview image to which the selected photographing mode is applied.

According to this, the user can take an image in a shooting mode suitable for the time and location of driving the camera.

25 is a flowchart illustrating a method of applying a shooting mode to which focus is applied according to a touch input according to an embodiment of the present invention. 26 to 29 are diagrams for describing an application of a photographing mode to which focus is applied according to a touch input according to an embodiment of the present invention.

Referring to FIG. 25, the controller 180 may receive a plurality of touch inputs on the preview image [S800] and adjust the focus based on the position and the number of times that the touch inputs are applied [S810].

FIG. 26 illustrates that the preview image 70 is displayed on the touch screen 151. The preview image 70 includes dogs e and persons as objects. The controller 180 can recognize each object included in the preview image 70.

As shown in FIG. 27, the user may touch to highlight the dog e. The controller 180 may focus only on the dog e among the objects included in the preview image 71. In FIG. 27, the state in which the dog e is focused is indicated by a solid line, and the state in which the focus is not focused on other objects is indicated by a dotted line.

As illustrated in FIG. 28, in the state of FIG. 27, the user may touch the dog e again. The controller 180 may focus more on the dog e and less on other objects among the objects included in the preview image 72. In FIG. 28, the state in which the dog e is more focused is indicated by a dark solid line.

As illustrated in FIG. 29, the user may touch the person g in the state of FIG. 27. The controller 180 may focus on the dog e and the person g from among the objects included in the preview image 72 and blur the other objects. In FIG. 29, the state in which the dog (e) and the person (g) is focused is indicated by a solid line, and the state in which the focus is not focused on other objects is indicated by a dotted line.

Assume that the user touches the person g in the state of FIG. 28. In this case, the controller 180 may focus on the person g and blur other objects while focusing more on the dog e among the objects included in the preview image 72. have.

Thereafter, when a touch input is applied to the photographing button 2, the controller 180 may capture a preview image to which a photographing mode in which the focus is adjusted differently for each object is applied.

According to this, it can be seen that the user's interest in the object that is most accurately focused is the highest, so that the user's gaze flow in the preview image can be easily understood.

30 is a flowchart illustrating a method of using information on an object included in an image captured by a specific application according to an embodiment of the present invention. 31 to 33 are diagrams for describing using information on an object included in an image captured by a specific application according to an embodiment of the present invention.

Referring to FIG. 30, the controller 180 may obtain and store information about an object recognized in the preview image and a user's voice when the preview image is taken [S900].

The controller 180 may store a user's voice when capturing the preview image. For example, as shown in FIG. 31, after the user parks, the user may capture a preview image 80 including a car. In this case, the user may make a voice of 'parking', and the controller 180 may receive and store the voice in association with the captured image.
