The haptic module 154 of the output unit 150 plays a role of generating various tactile effects that the user can feel. A typical example of the haptic effect generated by the haptic module 154 is vibration. By controlling the haptic module 154, the intensity and pattern of the generated vibration can be variously changed. For example, different vibrations may be synthesized and outputted or sequentially different intensity or pattern may be outputted .

The haptic module 154 can be implemented not only to transmit the tactile effect through direct contact but also to allow the user to feel the tactile effect through the muscular sense of the finger or arm.

On the other hand, in this embodiment, when a photographer photographs a photograph using a module of the camera 121 of the mobile terminal, the photographer can take an action and provide an interface by which the camera 121 can be controlled, And a control method thereof.

Hereinafter, for the sake of convenience, when the photographer takes a motion or a motion pattern in front of the camera 121, the camera 121 senses it, and the controller 180 executes a control command for the camera 121 corresponding to the motion, ) Is defined as a motion-shooting interface.

The main components for providing the motion picture taking interface among the components of the mobile terminal will be described in more detail as follows.

First, the camera module 121 mounted on the front and rear surfaces of the mobile terminal senses an image passing through the lens and transmits the sensed image to the controller 180 as a frame.

The controller 180 displays the current frame transmitted in real time on the touch screen, converts the frame into a digital file using the image processor 182 module of the controller 180, analyzes the digital file, Check if there is a specific motion pattern.

At this time, a specific motion may correspond to a signal received by the user in front of the camera 121, and a specific motion pattern may correspond to a change in the signal. For example, it is possible to take an OK indication with the hand of a user, or to designate a specific signal as a signal to be displayed by 1 to 5 using a finger, and a certain pattern in which the above-mentioned signal changes is referred to as a specific motion pattern .

That is, the user can input a motion to the terminal by taking various motions as described above in front of the lens of the camera 121. The image processing unit 182 analyzes the transmitted frame, Can be recognized.

A control command corresponding to the specific motion or a specific motion pattern is stored in the memory 160. The control command corresponding to the motion may be initially set to a default or may be set to a default Can be set or changed.

The camera 121 control command may include a shutter release command, a self-timer shutter release command, an enlargement or reduction shutter release command, or a flash on / off shutter release command.

When the image processing unit 182 recognizes the specific motion or the specific motion pattern, the controller 180 reads the camera 121 control command corresponding to the recognized specific motion or the specific motion pattern from the memory 160 , And the shooting of the camera 121 can be controlled to realize the motion-shooting interface.

<First Example >

Hereinafter, various embodiments using the motion photographing interface will be described in detail with reference to FIG. 2 to FIG.

2 shows a flow chart for providing a motion picture shooting interface according to the first embodiment of the present invention.

FIG. 3 shows a touch screen in a photographing preparation step in which no motion is input according to the first embodiment of the present invention, and FIG. 4 shows a touch screen in which motion is inputted according to the first embodiment of the present invention.

Referring to FIGS. 2 to 4, the controller 180 activates the camera 121 to enter a photographing preparation step when the user receives a camera module 121 execution command.

At this time, frames 10 to be sensed by the module of the camera 121 are displayed in real time on the touch screen, and a menu 11 and a shutter key for setting a motion photographing interface can be further displayed.

The control unit 180 provides a user with a setting of a motion photographing interface on / off, a specific motion or a specific motion pattern and a control command corresponding to the specific motions through the inputting of the motion photographing interface setting menu 11 .

For example, the user may touch the menu 110 to set the handset 200 displayed with the hand OK as a specific motion, and set a shutter release command with a control command corresponding to the OK handset 200 have.

The setting for the motion-shooting interface may be set to a default value in the memory 160, and may be directly set or changed by the user and stored in the memory 160 as described above. (S101)

When the motion photographing interface setting is completed in the photographing preparatory step, the image processing unit 182 analyzes whether there is a preset OK signal 200 in the frames sensed in real time in the camera module 121.

In this case, the specific motion is inputted by the user who is the photographer. In order to prevent the specific motion from being inputted by the motion of the subject, the specific motion recognized in the frame may require a certain size or more. That is, the image processor 182 may determine whether the motion is a specific motion considering the size of the motion object to be analyzed.

The image processor 182 recognizes a predetermined OK signal 200 in the frame transmitted from the camera 121 and transmits a motion input signal indicating that a specific motion has been input to the controller 180. [

At this time, the controller 180 may display an indicator 300 on the OK signal 200 to notify the user that the camera 121 is controlled by motion.

If the control unit 180 determines that a specific motion has been input in a situation in which the user does not want to do so, the user may touch the indicator 300 and the control unit 180 may return the specific motion as not being input. (S102)

However, when it is determined that the OK signal 200 is input by chance or the Oki signal 200 is input due to a noise or a malfunction, the controller 180 immediately issues a shutter release command to the camera 121 If not, a photograph that the user does not want may be photographed.

In order to prevent this, the controller 180 determines whether a specific motion is maintained for a predetermined time or more, and determines that the control command based on the specific motion is input only when the specific motion is maintained.

If the specific motion can not be maintained for a predetermined period of time, the control unit 180 determines that the command based on the specific motion is not input, and returns to the photographing preparation step.

If the specific motion is maintained for a predetermined time or longer, the control unit 180 changes the indication to the indicator 300 to inform the user that a control command corresponding to the specific motion is to be performed, To the user. (S103)

On the other hand, the user's specific motion is an interface for controlling the camera 121, and the user will not want to capture a specific motion.

Therefore, the image processing unit 182 determines whether the OK signal 200 is removed after a predetermined time has elapsed after a specific motion is input. (S104)

When the OK signal 200 is removed during the predetermined motion removal time, the image processor 182 recognizes the OK signal and notifies the control unit 180 of the OK signal. The control unit 180 recognizes this as a shutter release command and photographs the picture immediately after the camera 121 auto-focuses the image from which the OK signal 200 has been removed. At this time, the photographed photograph will be as shown in Fig. (S105)

If the controller 180 notifies the controller 180 that the OK signal 200 has not been removed within the predetermined motion removal time, the controller 180 takes an image including the OK signal 200 . At this time, the photographed photograph will be as shown in Fig. (S106)

From the above-described process, it is possible to take a picture by the motion photographing interface, and thus the user can easily obtain a shutter-release command without touching the mobile terminal, thereby obtaining a picture without shaking effectively.

Since such a motion photographing interface can be applied to various photographing situations or photographing modes, various embodiments using a motion photographing interface will be described below.

Hereinafter, common descriptions of the motion photographing interface described in the first embodiment of the present invention will be applied to the following embodiments in common, and a duplicate description will be omitted.

<2nd Example >

FIG. 5 is a flowchart showing a method of performing a self-timer photographing using a motion photographing interface according to a second embodiment of the present invention, and FIG. 6 is a flowchart illustrating a method of photographing a self- &Lt; / RTI &gt;

The self-timer photographing refers to a photographing method in which a user makes a shutter release command and takes a picture after a predetermined time (hereinafter, referred to as self-time) has elapsed.

5 to 6, the controller 180 receives a camera module 121 execution command from the user, activates the camera 121, and enters a photographing preparation step.

In the photographing preparatory step, the frames sensed by the camera module 121 are displayed on the touch screen in real time, and a menu for setting the motion photographing interface can be further displayed.

The user can set the motion photographing interface ON / OFF, the self-timer photographing motion or the motion pattern and the self time time corresponding to the motion through the motion photographing interface setting menu.

For example, the user can set the first pin 211 as the motion for executing the self-timer photographing command with the self time of 1 second in the self-timer photographing motion through the above menu.

In addition, as described above, the user can set the finger as the second number 212, the third number 213, and the fourth number 214 as the number of pins, and the self time is 2 seconds, Seconds, and 4 seconds, respectively. These settings are stored in the memory 160. (S201)

After the completion of the setting of the motion-shooting interface for the self-timer shooting, the image processing unit 182 analyzes the frames transmitted in real time through the camera 121 and transmits the received signals 211, 212, 213 , 214).

The control unit 180 transmits a signal indicating that the motion is inputted to the control unit 180 and the control unit 180 transmits the signal to the control unit 180 in response to the reception signals 211, 212, 213, , 214 are recognized on the touch screen. (S202)

Then, the control unit 180 determines whether the reception signals 211, 212, 213, and 214 are maintained for a predetermined period of time to prevent malfunction.

If the signals 211, 212, 213, and 214 are not held, the control unit 180 returns to the photographing preparatory step because the motion is not input. When the signals 211, 212, 213, If it is maintained, it is recognized as a self-timer shooting command and the process proceeds to the next step. (S203)

After the self-timer photographing command is recognized, the image processing unit 183 transmits to the controller 180 whether or not the received signals 211, 212, 213, and 214 are removed from frames transmitted in real time. (S204)

If the inputted signal 211, 212, 213, 214 is removed from the current frame, the controller 180 controls the camera 121 to change the image corresponding to the current frame from which the signal 211, 212, 213, Wait for the self-time, then shoot the AF again to acquire the photograph.

For example, if the input signal is the second signal 212 and the second signal 212 is removed after a predetermined time, the second image signal is captured two seconds after the second signal is removed, Self-timer shooting is possible. (S205)

On the other hand, if the input signals 211, 212, 213, and 214 are not removed, the controller 180 captures an image including the 211, 212, 213, and 214 after self-time to acquire a picture . (S206)

With the above-described method, it is possible to easily control the self-timer photographing with various self-time using the motion photographing interface, and there is an advantage that a high quality photograph can be obtained.

<Third Example >

FIG. 7 is a flowchart illustrating a method of photographing a photograph at various photographing setting values using a motion photographing interface according to a third embodiment of the present invention, and FIGS. 8 to 10 are flowcharts, Shows the handles controlling the various shooting modes.

The third embodiment of the present invention relates to a method for photographing by controlling the flash on / off, image enlargement / reduction (or zoom in / zoom out), brightness control, or the like during motion photographing using a motion photographing interface.

Referring to FIG. 7, the controller 180 receives a camera module 121 execution command from the user, activates the camera 121, and enters the photographing preparation step.

In the photographing preparatory step, the frames transmitted from the camera module 121 are displayed on the touch screen in real time, and a menu for setting the motion photographing interface is further displayed.

The user can designate the motion imaging interface on / off, the motion or motion pattern for changing the shooting set value, and the shooting setting value corresponding to the motion through the motion shooting interface setting menu.

For example, referring to FIG. 8, a user can designate a motion pattern in which the user fingers 222 after holding the fist 221 as a receiver with the camera 121 as a flashing motion pattern. Conversely, taking a motion pattern that grasps the fist 221 in the fisted state 222, the flash will turn off.

9, the user can set the motion pattern for adjusting the horizontal distance 233 between the index finger 232 and the thumb 231 to a command for controlling the brightness of the frame to be sensed.

Referring to FIG. 10, the user may set a motion pattern for adjusting the vertical distance 243 between the index finger 242 and the thumb 241 to zoom in / zoom out.

The control commands corresponding to the motion pattern and the motion pattern set in the above manner are stored in the memory 160. [ (S301)

When the motion imaging interface is set as described above, the image processing unit 182 analyzes the frame to check whether there is a predetermined motion.

If the image processing unit 182 recognizes that there is a predetermined motion, the image processing unit 182 transmits a signal informing the controller 180 that the motion has been inputted, and the controller 180 displays an indicator indicating that the motion is inputted on the touch screen. (S202)

Then, the controller 180 determines whether the input motion is maintained for a preset time period to prevent a malfunction. (S303)

If the controller 180 determines that the motion is not maintained for a preset time, the controller 180 returns to the photographing preparation step. If the motion is maintained, the controller 180 executes a control command corresponding to the motion.

For example, when a motion for widening the gap between the index finger 242 and the thumb 241 is input as a motion, the controller 180 reads out and executes a zoom-out command corresponding to the up-and-down motion in the memory 160. (S304)

Then, the image processor 182 notifies the controller 180 of the input motion when the motion is removed from the frame. (S305)

The control unit 180 recognizes that the motion is removed as a shutter release command, and photographs the image after autofocusing the image from which the motion has been removed. (S306)

In this way, it is possible to easily control the photographing setting values of the camera 121 by using the motion photographing interface, and at this time, it is possible to obtain high quality photographs by preventing the camera shake by controlling the mobile terminal by motion without directly touching have.
