First, a description will be given on the assumption that one camera, for example, the first camera 121 is included.

Referring to FIG. 4, the mobile terminal 100 determines whether the photographing mode is set for the first camera 121 under the control of the controller 180 (S410).

In response to the control of the controller 180, the mobile terminal 100 operates the first camera 121 as a user operation input means when the photographing mode is not set (S420). When the photographing mode is set, the first camera 121 is operated as photographing means (S430).

Here, the photographing mode may mean a state in which the camera module is activated to receive an image from the outside.

Next, it is assumed that a plurality of cameras, for example, a first camera 121 and a second camera 121 'are included.

Referring to FIG. 4, the mobile terminal 100 determines whether the photographing mode is set for each of the first camera 121 and the second camera 121 ′ under the control of the controller 180 (S410). .

In response to the control of the controller 180, the mobile terminal 100 determines that the first camera 121 is not set to both the first camera 121 and the second camera 121 ′ as a result of the determination. ) And the second camera 121 'are both operated as user operation input means (S420), and as a result of the determination, when the shooting mode is set in both the first camera 121 and the second camera 121', the first Both the camera 121 and the second camera 121 'are operated as photographing means (S430).

In addition, according to the control of the controller 180, the mobile terminal 100 does not have a shooting mode set in the first camera 121 (or the second camera 121 ′), and the second camera ( 121 ') (or the first camera 121), when the shooting mode is set, the first camera 121 is operated as a user operation input means (S420), and the second camera 121' is photographed. It is operated as (S430).

Hereinafter, for convenience of explanation, the description will be made only when the first camera 121 operates as a user operation input means and the second camera 121 'operates as a photographing means.

The mobile terminal 100, under the control of the controller 180, recognizes a user input operation with respect to the first camera 121 using a sensor (S440).

Here, the sensor may be included as a component of the sensing unit 140. In addition, the sensor may be provided inside the first camera 121 and may be electrically connected to recognize a user input operation with respect to the first camera 121.

In the recognizing step S440, when the first camera 121 rotates at a predetermined angle and in a predetermined direction (refer to FIGS. 3A and 3B) in response to a user input operation, the controller 180 of the first camera 121 may be configured. The user input operation may be recognized using the rotation angle and the rotation direction.

Alternatively, in the recognition step (S440), when the sensor includes a touch sensor that detects a touch from the user, the controller 180 may recognize a user input operation by using the direction, distance, and angle of the detected touch. Can be.

The mobile terminal 100 outputs a control signal corresponding to the user input operation recognized in the recognition step S440 under the control of the controller 180 (S450).

For example, the control signal may include a rotation command signal in a predetermined angle and a predetermined direction with respect to a lens provided in the second camera 121 ′ 1 to correspond to a user input operation with respect to the first camera 121. have. This means that the photographing range of the second camera 121 'can be adjusted by manipulating the first camera 121.

Alternatively, when a plurality of objects including the first and second objects are displayed through the display unit 151, the control signal may include an indicator movement command signal from the first object to the second object. This means that the first camera 121 can be operated as one direction key.
