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.

5 is a diagram showing a control method of selecting the horizontal / vertical photographing mode of the mobile terminal 100, according to an embodiment of the present invention.

When photographing / photographing a moving picture by using the mobile terminal 100, the user can select a photographing mode by rotating the touch screen 151. [ Hereinafter, terms such as the longitudinal direction and the width direction of the touch screen 151 are used. When the shape of the touch screen 151 is a right-angled rectangle, the same direction as a side having a relatively long length is referred to as a longitudinal direction, and the same direction as a side having a relatively short length is referred to as a width direction.

5, in photographing the subject / scenery 501, the first mobile terminal 100a displays the direction of the touch screen 151a in the vertical direction, the second mobile terminal 100b in the direction of the touch screen 151b are photographed in the horizontal direction. As in the first mobile terminal 100a shown in FIG. 5, the user can photograph the longitudinal direction of the touch screen 151 such that the longitudinal direction of the touch screen 151 is perpendicular to the ground. That is, when the first mobile terminal 100a determines that the lengthwise direction of the touch screen 151 is vertical to the ground via various sensors, it can perform shooting in the portrait mode. Similarly, when the second mobile terminal 100b determines that the lengthwise direction of the touch screen 151 is transverse to the ground through various sensors, the second mobile terminal 100b can perform shooting in the landscape mode. The portrait mode image 503a photographed in the portrait mode can be automatically output in the portrait direction when the user browses at a later time. Similarly, the horizontal mode image 503b photographed in the landscape mode can be automatically output in the horizontal direction when the user browses at a later time.

As described above, when the horizontal / vertical mode image is classified according to the photographing mode at the time of photographing, the user can view the rotated image automatically when viewing the image, thereby providing a more convenient photograph browsing environment There will be advantages.

In order to determine whether the longitudinal direction of the touch screen 151 is horizontal or vertical, the controller 180 generally uses a gyroscope sensor. However, there is a problem in that, depending on the gyroscope sensor, the horizontal / vertical mode can not be appropriately selected.

In other words, according to the above-described method, it may be appropriate when the direction of the camera 121 is horizontal to the ground. However, as the direction of the camera 121 approaches perpendicular to the ground, it becomes difficult to accurately switch. This is because the horizontal / vertical rotation of the touch screen is centered on the direction of the camera 121, and the gyroscope sensor determines the rotation of the mobile terminal 100 based on the gravity direction. Therefore, when the direction of the camera 121 and the paper plane are horizontal, it can easily be determined whether the lengthwise direction of the mobile terminal 100 is horizontal or vertical. However, when the direction of the camera 121 is perpendicular to the paper surface, if the touch screen 151 is rotated in the longitudinal direction, there is no change in the angle formed with the gravitational direction.

More specifically, it can be assumed that the mobile terminal 100 is used to photograph a subject on the floor (or a subject on the ceiling). In this case, the user will perform photographing while keeping the camera 121 of the mobile terminal 100 in the gravity direction. In this situation, the signal received through the gyroscope sensor must be the same when the longitudinal direction of the touch screen 151 is horizontal or vertical to the user and the gravity direction is the reference. This is because the camera 121 rotates while being directed toward the gravity direction.

Therefore, in one embodiment of the present invention, a control method for compensating the above problem is proposed. The control method according to the first embodiment of the present invention proposes to select the photographing mode based on the image photographed through the front camera 121. [ The control method according to the second embodiment of the present invention proposes to select the photographing mode based on the image photographed through the rear camera 121 '. Such an embodiment will be described in detail below with reference to the drawings.

6 is a flowchart of a control method for determining a shooting mode for an image shot through the rear camera 121 'based on an image shot through the front camera 121 according to the first embodiment of the present invention FIG.

The control method according to the first embodiment of the present invention distinguishes the front camera 121 and the rear camera 121 'and distinguishes between the front camera 121 and the rear camera 121' ) Is utilized.

Generally, if the user does not want to photograph himself or herself, the user takes a picture using the rear camera 121 '. This is because the direction of the front camera 121 is the same as that of the touch screen 151 and the rear camera 121 'is opposite. Accordingly, in order to check the preview screen through the touch screen 151, a photograph must be taken through the rear camera 121 '. In the following description for explaining an embodiment of the present invention, a control method of photographing an image through the rear camera 121 'will be described. However, this control method is applicable even when the front camera 121 is used You can do it.

In step S601, the controller 180 activates the front / rear cameras 121 and 121 'and displays a preview screen for the first image received through the rear camera 121' on the touch screen 151 Can be output.

In step S602, the control unit 180 determines a shooting mode for the first image based on the second image received through the front camera 121. [ Generally, the user shoots while watching a preview screen of the rear camera 121 'output through the touch screen 151. [ In such a case, the image received through the front camera 121 will likely include the user's face. Therefore, in the first embodiment of the present invention, the photographing mode is determined based on the face of the user received via the front camera 121. [ A specific method of the first embodiment will be described with reference to Figs. 7 to 8B.

7 is a diagram showing a conceptual diagram of a control method for analyzing the position of an eye in an image according to the first embodiment of the present invention.

7 (a) shows an image received through the front camera 121 when an image is captured through the rear camera 121 '. As described above, since the user can take an image using the rear camera 121 'while viewing the preview screen of the image received through the touch screen 151, the image received through the front camera 121 is , And a face portion of the user.

The control unit 180 can determine the position of the user's eyes by analyzing the image received through the front camera 121. [ Analysis of the image may use a face identification algorithm.

7 (b) is a diagram showing a position 701 of the eye analyzed in the image. The controller 180 may analyze the position 701 of the eye to determine whether the user views the touch screen 151 in the horizontal direction or in the vertical direction. Hereinafter, a method of determining the orientation of the touch screen 151 along the eye position 701 will be described with reference to Figs. 8A and 8B. Fig.

8A and 8B are views for explaining a case where the touch screen 151 is in the horizontal direction and the vertical direction is the vertical direction, And Fig.

Referring to FIG. 8A, a preview screen 502 is displayed in a state in which the longitudinal direction of the touch screen 151 is in the vertical direction with respect to the user's line of sight. Therefore, in the case of the photographing example shown in Fig. 8A, the user can intend to photograph in the portrait mode.

8A is a view showing an image received through the rear camera 121 'in the state of FIG. 8A (a).

Fig. 8A (c) is a diagram showing an image received through the front camera 121 in the state of Fig. 8A (a). FIG. 8A (d) is a diagram showing the position 701 of the eye determined by the control unit 180 in the image of FIG. 8A (c). When the eye position 701 is analyzed, the position of the left eye and the position of the right eye are arranged in the width direction of the touch screen 151. Therefore, based on the analyzed eye position 701, the control unit 180 determines that the photographing is being performed with the longitudinal direction of the touch screen 151 lying vertically on the basis of the line of sight viewed by the user . That is, the control unit 180 may determine that the user intends to take a picture in the portrait mode.

Referring to FIG. 8B, a preview screen 502 is displayed in a state in which the longitudinal direction of the touch screen 151 is in a horizontal direction with respect to the user's gaze. Therefore, in the case of the photographing example shown in Fig. 8B, the user may intend to photograph in the landscape mode.

8B is a diagram showing an image received through the rear camera 121 'in the state of FIG. 8B (a).

FIG. 8B is a diagram showing an image received through the front camera 121 in the state of FIG. 8B (a). FIG. 8B is a diagram showing the position 701 of the eye determined by the control unit 180 in the image of FIG. 8B (c). When the eye position 701 is analyzed, the position of the left eye and the position of the right eye are arranged in the longitudinal direction of the touch screen 151. Therefore, based on the analyzed eye position 701, the control unit 180 determines that the photographing is being performed with the longitudinal direction of the touch screen 151 lying horizontally on the basis of the line of sight viewed by the user . That is, the control unit 180 may determine that the user intends to take a picture in landscape mode.

Returning to FIG. 6, the control unit 180 determines whether an imaging command is received in step S603. If it is determined that no shooting command has been received, the control unit 180 returns to step S601. As a result of the determination, if the photographing command is received, the controller 180 may proceed to step S604.

In step S604, the control unit 180 may store the received first image in the selected mode.

In this case, the first method of storing the selected mode in the controller 180 may be an operation of storing the image mode together with the image mode.

The first method of storing the control unit 180 in the selected mode may be an operation of rotating and storing the received first image itself. That is, the control unit 180 can rotate and store the image taken in the portrait mode in the vertical direction and the image taken in the landscape mode in the horizontal direction.

In the first embodiment of the present invention described above, all of the front and rear cameras 121 and 121 'are used to determine the photographing mode. In the second embodiment of the present invention to be described below, a control method of determining a photographing mode using one camera for photographing will be described.

9 is a diagram illustrating a control method of analyzing an image received through a camera and determining an image capture mode using the analyzed result according to a second embodiment of the present invention. More specifically, the control unit 180 analyzes characters in the image and proposes to rotate the analyzed characters so that they are in the right direction.

9 (a), the controller 180 activates the front camera 121 or the rear camera 121 ', and displays a preview screen 502 of the activated cameras 121 and 121' on the touch screen 151, respectively.

9 (b) is a diagram showing an image received through the camera 121 or 121 'activated in the state of FIG. 9 (a). The image shown in FIG. 9B includes a text area 901 and characters included in the text area 901 move in the longitudinal direction 902 (from the upper end to the lower end) of the touch screen 151. In general, since the characters progress from left to right, the controller 180 may determine that the image of FIG. 9 (b) has been rotated 90 degrees clockwise. Therefore, the control unit 180 may set the photographing mode of the image to the landscape mode in the example shown in Fig. The control unit 180 can acquire a landscape mode image as shown in FIG. 9 (c).

In summary, the controller 180 according to an exemplary embodiment of the present invention may analyze a progress direction of a character included in the received image, and determine an image capture mode based on the analyzed progress direction.

In a third embodiment of the present invention, it is proposed to further utilize a geomagnetic sensor to determine a horizontal or vertical mode when photographing an image.

The geomagnetic sensor may be a sensor such as a compass to determine the rotated angle of the mobile terminal 100 based on the reference geomagnetic field direction (for example, the N-pole direction of the compass).

Generally, when only the gyro sensor is used, the rotation of the mobile terminal 100 can not be accurately determined when the direction of the camera coincides with the gravity direction. Therefore, in the third embodiment of the present invention, it is proposed to use the geomagnetic sensor to improve the above-described inaccuracy.

10 is a diagram illustrating a control method of determining a photographing mode for an image to be photographed based on rotation of the mobile terminal 100 sensed through a geomagnetic sensor according to a third embodiment of the present invention.

Referring to FIG. 10A, when the camera is activated, the mobile terminal 100 is displayed on the touch screen 151 as shown in FIG. 10 (b) The preview screen 502 can be output. In the example of FIG. 10 (b), the control unit 180 assumes that the photographing mode of the image is the portrait mode.

In the embodiment shown in Fig. 10, the case is directed to the bottom of the direction of the camera. When the direction of the camera is in the same direction as the gravity direction (or in the direction substantially close to the gravitational direction), the control unit 180 can hardly detect the rotation of the mobile terminal 100 through the gyroscope sensor. This is because, as described above, the gyroscope sensor can sense only the rotation in the reference direction of gravity direction. Therefore, in the third embodiment of the present invention, it is proposed to further utilize the geomagnetic sensor to suit the situation as in the above example.

When the camera 121 detects the rotation of the mobile terminal 100 through the geomagnetic sensor while the camera 121 is activated, the control unit 180 changes the shooting mode from the portrait mode to the landscape mode (or vice versa) (See Fig. 10 (c)). Since the photographing direction of the camera is directed toward the bottom, a geomagnetic sensor that senses the rotation in the reference direction of the N pole direction 1001 will be able to detect a more accurate rotation. However, when the photographing mode is the landscape mode before the rotation is detected, the controller 180 switches from the landscape mode to the portrait mode according to the rotation detection It will be possible.

According to an embodiment of the present invention, a control method of applying a rotation to a moving image to be stored according to a rotation change sensed during shooting a moving image is further proposed. This embodiment will be described with reference to Figs. 11 and 12. Fig.

11 is a diagram illustrating a control method of detecting the rotation of the mobile terminal 100 during shooting of a moving image and switching a stored moving image on the basis of the detected result, according to an embodiment of the present invention . FIG. 12 is a diagram showing a reproducing method of moving images stored by FIG.

11A is a diagram showing a moving picture shooting state diagram photographed in the landscape mode. That is, the longitudinal direction of the touch screen 151 of FIG. 11 (a) is horizontal to the ground, and the first to third embodiments of the present invention can be applied as a control method of detecting such a direction It will be self-evident.

11 (a), when the mobile terminal 100 is rotated such that the longitudinal direction of the touch screen 151 is perpendicular to the paper surface by the user while being photographed in the landscape mode, To a portrait mode to store moving images.

The operation of changing the shooting mode from the horizontal mode to the vertical mode (or vice versa) during recording of the moving image and storing it may be implemented by the following methods. This method will be described together with reference to FIG. Figs. 12A and 12B are views showing reproduction state diagrams of a moving picture, and can output a reproduction indicator 1201 indicating reproduction state.

As a first method, the control unit 180 may also rotate and store the direction of moving images stored according to the rotation of the mobile terminal 100. [ 12 (a) to 12 (b)) so as to correspond to the point in time of the rotation during the recording, as shown in Fig. 12 by the control unit 180, Lt; / RTI >

As a second method, when the rotation of the mobile terminal 100 is detected during the recording, the controller 180 records only the time and / or direction of the rotation of the mobile terminal 100, . That is, the control unit 1800 stores the moving image regardless of the rotation. The moving image stored in the control unit 1800 corresponds to the point of time corresponding to the time when the rotation occurred during the recording as shown in FIG. 12 (Switching from (a) to (b) in Fig. 12) and reproducing the reproduced data, thereby obtaining the same effect as the first method.
