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 of an object approaching a predetermined detection surface, or the presence of an object in the vicinity of the detection surface, without mechanical contact by using electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in the inner area of the mobile terminal or in proximity to the touch screen, which is covered by the touch screen.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. 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, the act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as "proximity touch & The act of actually touching an object on the screen is called a "contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 141 can detect a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, have. Meanwhile, the control unit 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141 as described above, and further provides visual information corresponding to the processed data It can be output on the touch screen. Furthermore, the control unit 180 can control the mobile terminal 100 such that different operations or data (or information) are processed according to whether the touch to the same point on the touch screen is a proximity touch or a touch touch .

Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

Thus, 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 transmits the corresponding data to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like. Here, the touch controller may be a separate component from the control unit 180, and may be the control unit 180 itself.

On the other hand, the control unit 180 may perform different controls or perform the same control according to the type of the touch object touching the touch screen (or a touch key provided on the touch screen).

Touch can be sensed.

The ultrasonic sensor can recognize the position information of the object to be sensed by using ultrasonic waves. Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.

The camera 121 includes at least one of a camera sensor (for example, a CCD, a CMOS, etc.), a photo sensor (or an image sensor), and a laser sensor.

The photosensor can be laminated to the display element, which is adapted to scan the movement of the object to be detected proximate to the touch screen. More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of change of light, and position information of the object to be sensed can be obtained through the calculation.

Another example of an accessory is a touch pen for supplementing or extending a touch input to the touch screen.

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 showing a control method of the mobile terminal 100 according to the first embodiment of the present invention.

2, the control unit 180 of the mobile terminal 100 enters a shooting mode and displays a preview image input through the camera 121 on the display unit 151 (S210). Specifically, when the control unit 180 receives the predetermined input, it can enter the photographing mode. The predetermined input may be a hard key (e.g., a volume button or a home button) provided in the main body of the mobile terminal 100 or a soft key displayed in a specific area of the display unit 151 Icon or the like. However, the predetermined input for the control unit 180 to enter the photographing mode is not limited to the examples described above. For example, the control unit 180 may enter the photographing mode upon receipt of a voice input instructing to enter the photographing mode.

Next, the controller 180 sets the preview image of the first viewpoint as a contrast image (S220). Here, the first viewpoint may be a time point when a predetermined input for commanding the generation of the contrast image is received from the user. As an example, the point of time when the touch input to the preview image to be used as the background of the subject is received may be the first point of time described above. Also, the contrast image may mean an image to be compared with a preview image displayed after the first time point, in order to detect a subject not displayed before the first time point from the preview image displayed after the first time point. The control unit 180 may store the contrast image in the memory 170 and may delete the contrast image in the memory 170 when the photographing is completed. In addition, the control unit 180 may display the contrast image stored in the memory 170 in a thumbnail format on one side of the preview image at the first viewpoint.

Next, the controller 180 compares the preview image at the second time point with the contrast image set at the step S220, and detects the newly appeared subject on the preview image at the second time point (S230). Here, the second time point may mean a specific time point after the first time point. Alternatively, the second viewpoint may mean a time range immediately after the first viewpoint and before the photographing.

At this time, the control unit 180 can generate a predetermined visual effect on the detected object. For example, the control unit 180 may display the detected frame of the subject with a bold line or a dotted line so that the user can distinguish the detected subject from other subjects displayed on the preview image at the second viewpoint.

If it is determined that there is no new object on the preview image at the second time point as a result of the comparison with the contrast image, the control unit 180 displays a message informing that the preview image at the second time point is the same as the contrast image, 151 or the sound output unit 152 via the audio output unit 152.

Next, the control unit 180 selects at least one of the photographed objects through step S230 (S240). The selection for the detected subject may be based on user input. For example, when the controller 180 receives a touch input for a position of the preview image at the second time point, the controller 180 can select a subject corresponding to the position at which the touch input is received. Of course, when the subject corresponding to the position at which the touch input is received is not a newly appearing subject in the preview image at the second time point, the control unit may not select the subject at the touched position.

Then, the control unit 180 adjusts the size of the selected object through step S240 according to a predetermined input (S250). At this time, the predetermined input for adjusting the size of the subject may be a push input for a touch input, a hard key, etc. for the display unit 151 and the like. Also, the controller 180 may adjust the size of the subject according to the movement of the main body of the mobile terminal 100 or the distance to the photographer.

If the control unit 180 reduces the size of the subject, an area of the contrast image corresponding to the subject may be displayed in the area where the subject is displayed before reduction.

It is apparent to those skilled in the art that the type of the input that is predetermined to adjust the size of the subject is not limited to the above-described example, and that the size of the subject can be adjusted through various other input methods such as voice input.

In addition, the control unit 180 can adjust the position in the preview image of the selected subject through step S240 according to a predetermined input, separately from the subject size adjustment or the subject size adjustment. For example, when the controller 180 receives the touch and drag input for one of the newly appeared objects in the preview image at the second time point, the control unit 180 displays the touched object on the preview image at the second time point to a position corresponding to the drag direction and distance So that it can be displayed.

In operation S260, the controller 180 may capture a preview image at a second point of time at which the size-adjusted subject is superimposed at step S250. At this time, the controller 180 can capture the preview image of the second time point as soon as the size adjustment of the subject through the step S250 is completed. Alternatively, the control unit 180 may perform shooting upon receiving an input for selecting a shooting icon displayed on the display unit 151 in a state in which the size-adjusted subject is superimposed on the preview image at the second time point. Alternatively, when the overlapping state of the subject whose size is adjusted on the preview image at the second time point exceeds a predetermined time limit, the control unit 180 may perform shooting without receiving a separate user input. However, the scope of the present invention is not limited to the above-described example, and the control unit 180 may receive various types of input such as voice corresponding to the photographing function, movement of the main body, Can be performed. The control unit 180 may store the photographed image in the memory 170 or transmit the photographed image to another electronic device through the wireless communication unit 110. [

Hereinafter, the mobile terminal 100 according to the first embodiment of the present invention will be described in more detail with reference to FIG. 3 to FIG.

FIG. 3 is a view for explaining an example in which the mobile terminal 100 according to the first embodiment of the present invention sets a preview image as a contrast image C1.

3 (a), the controller 180 displays the first operation area 210, the second operation area 220, and the preview area 310 on the display part 151 at the time of entering the photographing mode Can be displayed. In the first operation area 210, icons corresponding to functions such as flash setting, front / rear camera switching, mode selection, shooting environment setting, and the like can be displayed. In the second operation area 220, an icon corresponding to functions such as photo / moving picture switching, photographing execution 221, and viewing of photographed photographs can be displayed. 3 (a) and the types of the icons displayed in the first operation area 210 and the second operation area 220. The first operation area 210, the second operation area 220, , The number, and the positions are by way of example, and are not limited thereto. For example, the first operation area 210 and the second operation area 220 may not be displayed or may be displayed together in one area.

In addition, the controller 180 may display a preview image of a predetermined photographing direction input through the camera 121 in the preview area 310. 3 (a), the preview area 310 is shown as being disposed between the first operation area 210 and the second operation area 220, but the present invention is not limited thereto. For example, the control unit 180 sets the preview area 210 to the entire area of the display unit 151, and displays the first operation area 210 and the second operation area 220 on the preview area 310 You may.

On the other hand, the predetermined photographing direction means a direction in which the camera 121 is oriented. For example, when the camera 121 is disposed on the front side of the mobile terminal 100, the preview image displayed on the preview area 310 may be for the front side.

The control unit 180 checks the preview image P1 at the time point when the predetermined input is received (that is, at the first time point) while displaying the preview image continuously input through the camera 121 in the preview area 310 Can be set to the image (C1).

At this time, the predetermined input to set the preview image P1 at the first time point to the contrast image C1 may be received through various methods such as touch input, voice input, body movement, and the like. 3 (b), the control unit 180 displays a preview image at the time of receiving the touch input 410 for tapping one point in the preview area 310 once, The same control image C1 may be set in the same memory 170 and stored in the memory 170. [ For example, the control unit 180 may compare the preview image at the time of receiving the touch input (not shown) for long-pressing the photographing button of the second operation area 220 to the same reference image C1 , And may be stored in the memory 170. [

3 shows that a person is displayed as a subject S0 in the preview image P1 at the first view point, but this is an example and is not limited to the preview image of the first viewpoint P1, it is needless to say that no object is displayed or more objects may be displayed.

FIG. 4 is a diagram for explaining an example in which the mobile terminal 100 according to the first embodiment of the present invention detects and selects a new object appearing on a preview image.

4, the control unit 180 sets the preview image P1 at the first time point to the reference image C1 through the above-described method with reference to FIG. 3, It can be confirmed that the first subject S1 corresponding to the new person is displayed on the preview image P2 at the second time point as a new person comes in the shooting direction. As described above, in the present invention, the second viewpoint may be any one of a time range from the first point of view to a point of time before the photographing, or a time range from the first point of time until the photographing.

The control unit 180 detects the new object S1 in the preview image P2 at the second time point. Specifically, the control unit 180 compares the contrast image C1 with the preview image P2 at the second time point to determine whether the subject that is not displayed in the contrast image C1 exists in the preview image P2 at the second time point . For example, the control unit 180 does not detect the subject S0 that is commonly displayed in the contrast image C1 and the preview image P2 at the second time point, but does not detect the subject S0 in the preview image at the second time point, Only the first subject S1 displayed only in the image P2 can be detected.

The control unit 180 can generate a predetermined visual effect on the subject S1 detected as newly appeared in the preview image P2 at the second time point. Referring to FIG. 4B, the controller 180 may display the frame of the first subject S1 as a dotted line to distinguish it from the other objects S0 in the preview image P2 at the second time point have.

In addition, the controller 180 may select at least one of the subjects S1 detected in the preview image P2 at the second time point as the subject O1 whose size or position is to be changed. At this time, the control unit 180 can select at least one of the objects S1 detected in the preview image P2 at the second time point according to a predetermined input. For example, as shown in FIG. 4B, when the touch input 420 for tapping any one of the detected objects S1 is received, the control unit 180 displays the touch input corresponding to the position The subject S1 can be selected and the selected subject S1 can be set as the subject O1. If there is one detected object in the preview image P2 at the second time point, the control unit 180 may automatically select the object without further input.

The control unit 180 can generate a predetermined visual effect on the subject selected as the subject O1. At this time, the control unit 180 can generate a visual effect different from the visual effect described above with reference to FIG. 4 (b) for the object O1. For example, referring to (c) of FIG. 4, the controller 180 determines whether the first subject S1 selected through the touch input 420 as shown in FIG. 4 (b) Brightness and the like can be changed. In addition, the control unit 180 may store the object O1 in the memory 170. [ Also, the control unit 180 may convert the target subject O1 into a thumbnail (not shown) format and display it on one side of the display unit 151. [

Hereinafter, a method of adjusting the size of the subject S1 according to various input methods will be described with reference to FIGS. 5 to 9. FIG.

5 is a view for explaining an example in which the mobile terminal 100 according to the first embodiment of the present invention adjusts the size of a subject according to a touch input to a subject.

5A, when the controller 180 receives the touch inputs 431 and 432, which are pinch-in touches with respect to the subject O1, the controller 180 reduces the size of the subject O1, And can be displayed on the image P2. 5 (a), when the distance between the touch inputs 431 and 432 received at two different positions in the target object O1 approaches a predetermined direction, The size of the object O1 can be reduced to a degree corresponding to the changed distance and direction between the touch inputs 431 and 432 as shown in FIG.

5B, when the control unit 180 receives the pinch-out touch inputs 441 and 442 for the subject O1, the controller 180 enlarges the size of the subject O1 to obtain the second And can be displayed on the preview image P2 of the viewpoint. Specifically, when the distance between the touch inputs 441 and 442 received at two different positions in the target subject S1 approaches along a predetermined direction, the control unit 180 determines whether the distance between the touch inputs 441 and 442 The size of the object O1 can be enlarged to a degree corresponding to the changed distance and direction between the touch inputs 441 and 442 as shown in FIG.

6 is a view for explaining an example in which the mobile terminal 100 according to the first embodiment of the present invention adjusts the size of the subject according to the distance to the photographer.

The control unit 180 can calculate the distance to the photographer based on the signal output from the distance sensor 143. [ At this time, the distance sensor 143 can output a signal corresponding to the distance to the sensed photographer in various ways. For example, the distance sensor 143 may emit infrared rays, ultrasonic waves, or laser beams toward the photographer, and may output different signals corresponding to the distance to the photographer depending on the time and amount of the reflected light reflected by the photographer. The distance sensor 143 may include at least one of a proximity sensor 141, an infrared sensor, an ultrasonic sensor, or a laser sensor.

6A, when the distance between the mobile terminal 100 and the photographer is greater than the distance from the second viewpoint, the controller 180 reduces the size of the subject O1 to the second viewpoint Can be displayed on the preview image P2 of FIG.

6 (b), the controller 180 enlarges the size of the subject O1 as the distance between the mobile terminal 100 and the photographer becomes closer to the distance from the second viewpoint And can be displayed on the preview image P2 at the second time point.

On the other hand, if the distance between the main body of the mobile terminal 100 and the photographer is detected to be greater or smaller than a predetermined first threshold value based on the signal received from the distance sensor 143, , The camera 121 may be inactivated to fix the preview image P2 displayed on the display unit 151 and to reduce or enlarge the size of the subject O1 only. In this case, the first threshold value may be a predetermined value so as not to be affected by a minute distance change between the main body of the mobile terminal 100 and the photographer. Accordingly, even if the photographer moves the mobile terminal 100 to adjust the size of the subject O1, the preview image P2 at the second time point, which is the background of the subject O1, can be maintained in a fixed state , The photographer can adjust only the size of the object subject O1 as desired.

7 is a view for explaining an example in which the mobile terminal 100 according to the first embodiment of the present invention adjusts the size of a subject in accordance with movement of the main body.

The control unit 180 can calculate the motion of the main body of the mobile terminal 100 based on the signal output from the motion sensor 144. [ At this time, the motion sensor 144 can output a signal corresponding to the motion of the main body of the mobile terminal 100 by various methods. The movement sensor 144 may include at least one sensor capable of sensing movement of the main body of the mobile terminal 100 such as a gyroscope, an accelerometer, or a magnetic sensor . The gyro sensor can acquire a rotation speed or an angular velocity corresponding to the rotation of the mobile terminal 100 on the axis line, that is, the rotation of the mobile terminal 100. In addition, the acceleration sensor can acquire the acceleration of gravity according to the movement of the mobile terminal 100. [ Also, the geomagnetic sensor can acquire the orientation of the mobile terminal 100 like a compass.

The control unit 180 may be configured to receive a signal related to at least one of the angular velocity obtained through the gyro sensor of the motion sensor 144, the gravitational acceleration obtained through the acceleration sensor, or the attitude of the main body of the mobile terminal 100 obtained through the geomagnetic sensor, A direction, a distance, a velocity, an angle, and the like of the mobile terminal 100 can be calculated on the basis of the information. The movement of the mobile terminal 100 may include tilting or shaking of the mobile terminal 100 body. Here, tilting may refer to a tilting of the mobile terminal 100 that varies with respect to at least one of the three-dimensional mutually orthogonal x-axis, y-axis, and z-axis. For example, when the x-axis is the horizontal axis of the main body, the main body of the mobile terminal 100 is tilted forward or backward, and when the y-axis is the vertical axis of the main body, the main body of the mobile terminal 100 is tilted to the left or right, Direction, it can be tilted clockwise or counterclockwise.

Referring to FIG. 7 (a), it can be seen that the main body of the mobile terminal 100 is inclined forward with respect to the horizontal axis passing through the center of the main body. In this case, the controller 180 determines that the movement of the main body of the mobile terminal 100 is tilted forward based on the signal output from the motion sensor 144, and determines the size of the subject O1 Can be reduced and displayed on the preview image P2 at the second time point.

Referring to FIG. 7 (b), it can be seen that the main body of the mobile terminal 100 tilts backward with respect to the horizontal axis passing through the center of the main body. In this case, the controller 180 determines that the movement of the main body of the mobile terminal 100 tilts backward based on the signal output from the motion sensor 144, and determines the size of the subject O1 Can be enlarged and displayed on the preview image P2 at the second time point.

It goes without saying that the controller 180 can reduce or enlarge the size of the subject O1 corresponding to the size or speed of the angle of inclination forward or backward of the main body of the mobile terminal 100. [

On the other hand, when it is detected that a motion of a predetermined second threshold value or more has occurred in the main body of the mobile terminal 100 based on the signal received from the motion sensor 144, the controller 180 deactivates the camera 121, The preview image displayed on the display 151 can be fixed and the size of the subject S1 can be reduced or enlarged. At this time, the second threshold value may be a preset value so as not to be influenced by minute movements of the main body of the mobile terminal 100. Accordingly, even if the photographer generates a motion in the mobile terminal 100 to adjust the size of the subject O1, the preview image P2, which is the background of the subject O1, can remain fixed, The position and size of the subject O1 can be adjusted in accordance with the intention of the user in accordance with the composition of the preview image P2 which is fixedly displayed.

FIG. 8 is a diagram for explaining an example in which the mobile terminal 100 according to the first embodiment of the present invention adjusts the size of a subject through an icon displayed on the display unit 151. FIG.

The control unit 180 displays icons 321 and 322 corresponding to the size adjustment of the target subject S1 on one side of the display unit 151 and receives an input for selecting one of the icons, Can be reduced or enlarged. At this time, the controller 180 may display the icons 321 and 322 corresponding to the size adjustment of the subject S1 in the area where the subject S1 is displayed.

8A, when the controller 180 receives a touch input for the icon 321 corresponding to the reduction of the size of the target subject S1, The size can be reduced and displayed on the preview image P2 at the second time point.

8B, when a touch input to the icon 322 corresponding to the enlargement of the target subject O1 is received, the size of the target subject O1 is enlarged as shown on the right side And can be displayed on the preview image P2 at the second time point.

9 is a view for explaining an example in which the mobile terminal 100 according to the first embodiment of the present invention adjusts the size of a subject through an operation unit provided in the main body.

The control unit 180 can reduce or enlarge the size of the subject S1 based on a signal input through the operation unit provided in the main body of the mobile terminal 100. [ For example, the operation unit for reducing the size of the subject or outputting a signal corresponding to the enlargement may be the second operation unit 123b described above with reference to Fig. 1C.

In addition, the controller 180 may change the function of the mobile terminal 100 controlled through the operation unit according to the mode or operation screen of the mobile terminal 100. For example, the control unit 180 may adjust the volume of the music through the operation unit in the music playback mode, and may adjust the size of the subject S1 through the operation unit in the shooting mode according to the first embodiment of the present invention.

9A, when the control unit 180 receives the push input for the lower end region of the second operation unit 123b, it reduces the size of the object O1 as shown on the right side, And can be displayed on the preview image P2 at the time point 2.

9B, when the control unit 180 receives the push input for the upper area of the second operation unit 123b, the control unit 180 enlarges the size of the subject O1 as shown on the right side And can be displayed on the preview image P2 at the second time point.

9 (a) and 9 (b), the size of the object S1 is controlled through the push input to the second operation unit 123b. However, this is merely an example, and the second operation unit The control unit 180 can receive signals input from other components such as the first operation unit 123a in FIG. 1B in addition to the second operation unit 123b, It is needless to say that the size of the subject O1 can be adjusted.

5 to 9 show the touch input, the distance to the photographer, the movement of the main body, the icon, and the method of adjusting the size of the object O1 through the operation unit, but this is merely an example, Can adjust the size of the subject O1 according to various types of input such as voice input.

Although not shown, the control unit 180 can automatically adjust the size of the subject O1 to match the size of another subject in the preview image P2 at the second time point. The control unit may calculate the size of the subject S0 other than the target subject O1 in the preview image P2 at the second time point and adjust the size of the subject O1 to be the size of the subject S0 having a different size . For example, when the area occupied by the other object S0 in the preview image P2 at the second time point is '10' and the area occupied by the object subject O1 is '15', the control unit determines that the object O1 Can be converted into 2/3 times the size and displayed on the preview image P2 at the second time point.

10 is a flowchart showing a control method of the mobile terminal 100 according to the second embodiment of the present invention.

Referring to FIG. 10, the controller 180 enters a shooting mode and displays a preview image for the first direction (S1010). In this case, the first direction may be the photographing direction of the first camera (121a in FIG. 1B) provided on the front surface of the mobile terminal 100 main body. For example, the user can check the preview image in the first direction, which is displayed as a subject, through the first camera 121a at the time of self photographing.

Next, the controller 180 selects at least one of the subjects of the preview image in the first direction (S1020). At this time, the controller 180 generates a predetermined visual effect on the subject displayed in the preview image P11 in the first direction, and displays the visual effect so as to be distinguished from other parts.

The control unit 180 may select at least one of the subjects of the preview image in the first direction according to a predetermined input. For example, when the touch input for one position of the preview image in the first direction is received, the subject displayed at the position where the touch input is received can be selected.

The control unit 180 can set the selected subject as a subject. The control unit 180 may store the subject set as the subject of interest in the memory 170. [ Also, the control unit 180 may display a subject set as a subject as a thumbnail on one side of the display unit 151. [ The target object displayed in the thumbnail format disappears temporarily in the preview area and can be displayed again in the preview area when it is received at the touch input for the thumbnail.

Next, the control unit 180 displays the selected object on the preview image for the second direction through step S1020 (S1030). That is, the controller 180 may display the preview image for the second direction to be the background of the subject.

Here, the second direction may be a photographing direction of the first camera 121a which is changed as the movement of the main body of the mobile terminal 100 occurs. For example, when the user moves while holding the mobile terminal 100, a preview image of a direction different from the direction before the movement (i.e., the first direction) (i.e., the second direction) Lt; / RTI >

Alternatively, the second direction may be a photographing direction of a second camera (121b in Fig. 1C) different from the first camera 121a. For example, after at least one subject is selected through step S1020, the control unit 180 activates the second camera 121b in which the second direction is the photographing direction, and displays on the display unit 151 in the second direction Can display a preview image of the image. The control unit 180 activates the second camera 121b automatically or activates the second camera 121b in accordance with the predetermined input, if preview of at least one subject is completed through step S1020, The preview image for the second direction can be displayed in the area.

Then, the control unit 180 adjusts the size of the selected subject (i.e., the subject subject) through step S1020 according to a predetermined input (S1040). At this time, the position of the subject can be adjusted separately from the size or the size. Since the preview image for the second direction is displayed together as the background, the user can be helped to appropriately adjust the size of the subject in accordance with the composition of the preview image for the second direction.

Next, the control unit 180 captures the preview image of the second direction in which the size-adjusted subject is superimposed (S1050). The photographing of the preview image in the second direction in which the size-adjusted subject is superimposed can be performed in the same manner as described above with reference to FIG. 2, so a detailed description thereof will be omitted.

Hereinafter, the mobile terminal 100 according to the second embodiment of the present invention will be described in more detail with reference to FIGS. 11 to 15. FIG.

11 is a diagram for explaining an example in which the mobile terminal 100 according to the second embodiment of the present invention selects a specific subject in the preview image P11 for the first direction.

The controller 180 displays the preview image P11 for the first direction input through the first camera 121a on the preview area 310 and detects the object displayed on the preview image P11 for the first direction can do. At this time, the control unit 180 can detect the subject displayed in the preview image P11 for the first direction in the same manner as described above with reference to Figs. 2 to 4 for the first embodiment. Alternatively, the control unit 180 may detect only a subject corresponding to a specific type of the preview image P11 for the first direction. For example, the control unit 180 may detect only a subject corresponding to a person in the preview image P11 for the first direction based on the face region extraction algorithm. Alternatively, the control unit 180 may detect the subject along the outline indicated by the preview image P11 in the first direction.

Referring to FIG. 11A, the second subject S2 and the third subject S3 may be displayed on the preview image P11 in the first direction. The control unit 180 can detect the second subject S2 and the third subject S3 in the preview image P11 for the first direction using at least one of the above-described methods. At this time, the control unit 180 can generate a predetermined visual effect on the detected object, and display it so as to be distinguished from other parts. For example, the controller 180 may display the detected edges of the second subject S2 and the third subject S3 in a dotted line format as shown in FIG. 11 (a).

The control unit 180 can select at least one of the preview images P11 for the first direction according to a predetermined input. For example, referring to FIG. 11A, the controller 180 may tap a position of the preview image P11 for the first direction in which the second subject S2 and the third subject S3 are displayed Upon receiving the touch input 450, the third subject S3 corresponding to the position at which the touch input 450 is received can be selected.

When at least one of the subjects S2 and S3 of the preview image P11 in the first direction is selected, the control unit 180 determines whether or not the selected subject S3 is the selected one as shown in (b) It is possible to generate a predetermined visual effect for changing brightness, contrast, transparency, and the like so as to be distinguished from other parts. The control unit 180 may set the selected subject S2 as the subject O3 and store the selected subject S2 in the memory 170. [

12 is a view for explaining an example in which the mobile terminal 100 according to the second embodiment of the present invention displays a thumbnail corresponding to the selected object in FIG.

The control unit 180 may display the selected object (i.e., the object of interest) on one side of the display unit 151 in a thumbnail format. For example, when the controller 180 receives the touch input 460 for dragging the object O3 to the second operation area 220 as shown in FIG. 12A, The subject O3 can be displayed in the form of a thumbnail 223 on one side of the second operation area.

12B shows that the subject O3 is displayed together with the corresponding thumbnail 223. When the thumbnail of the subject O3 is generated, The target subject O3 may disappear at step 310.

13 is a diagram for explaining an example of a predetermined input for the mobile terminal 100 according to the second embodiment of the present invention to display a preview image P21 for the second direction.

The control unit 180 activates the second camera 121b to preview the second direction when the selection of the specific object is completed in the preview image P11 for the first direction input through the first camera 121a, The image P21 can be displayed in the preview area 310. [ At this time, the controller 180 may activate the second camera 121b to display the preview image P21 in the second direction in the preview area 310 according to a predetermined input.

Referring to FIG. 13A, when the controller 180 receives an input for selecting the icon for switching the front / rear camera 121 displayed in the first operation area 210, the controller 180 activates the second camera 121b can do.

13B, the control unit 180 controls the movement of the mobile terminal 100 based on a signal inputted through the motion sensor 144, It is possible to activate the second camera 121b. Accordingly, the second camera 121b can be activated by moving the main body of the mobile terminal 100 without the need for the photographer to input an input for selecting the conversion icon of the front / rear camera 121 directly with the other hand, The preview image in the other direction can be displayed on the display unit 151 with only one hand.

14 illustrates an example in which the mobile terminal 100 according to the second embodiment of the present invention displays a subject selected in the preview image P11 for the first direction on the preview image P21 for the second direction FIG.

Referring to FIG. 14A, the controller 180 activates the second camera 121b according to a predetermined input as described above with reference to FIG. 13, and displays the preview area 310 in the second direction A preview image P21 may be displayed. At this time, when the subject object O3 is displayed in the form of a thumbnail 223, the control unit 180 may not display the subject object O3 in the preview area 310. [

In this case, the control unit 180 may display the target object O3 corresponding to the thumbnail 223 on the preview image P21 for the second direction in accordance with the input for selecting the thumbnail 223. [ For example, when receiving a touch input for tapping a thumbnail 223 displayed on one side of the second operation area 220 as shown in FIG. 14 (a), the controller 180 displays the thumbnail 223, The subject object O3 corresponding to the preview image P21 at the second time point can be displayed.

FIG. 15 is a view for explaining an example in which the mobile terminal 100 according to the second embodiment of the present invention changes the position of a subject displayed on a preview image.

The control unit 180 displays the selected object in the preview image P11 in the first direction on the preview image P21 for the second direction in the same direction as the previous position in which the object was selected Can be displayed.

However, if the user desires to display the target object at another position of the preview image P21 for the second direction, the control unit 180 determines whether the target subject is the preview image P21 for the second direction, To be displayed at different positions on the screen, or to reduce or enlarge the size.

For example, when the controller 180 receives the touch input 470 for dragging the target subject O3 as shown in FIG. 15A, the control unit 180 determines whether or not the touch input 470 corresponding to the dragged distance and direction The subject O3 can be moved to the position. For example, although not shown, the control unit 180 controls the magnitude of the subject O3 displayed on the preview image P21 for the second direction according to a predetermined input with reference to FIGS. 5 to 9 It is needless to say that it can be adjusted similarly to the above-described method.

According to the second embodiment of the present invention, a subject displayed in any one of the preview images for two different directions can be superimposed on the preview image for the remaining directions to obtain a new type of shot image. Thereby, even if the subject existing in one shooting direction is not moved in the other shooting direction, it is possible to obtain a shot image that is the same as that actually shot in another shooting direction.
