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 .

The touch sensor uses a touch (or touch input) applied to the touch screen (or the display unit 151) by using at least one of various touch methods such as a resistance film type, a capacitive type, an infrared type, an ultrasonic type, Detection.

For example, the touch sensor may be configured to convert a change in a pressure applied to a specific portion of the touch screen or a capacitance generated in a specific portion to an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, a capacitance at the time of touch, and the like where a touch object touching the touch screen is touched on the touch sensor. 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). Whether to perform different controls or to perform the same control according to the type of the touch object may be determined according to the current state of the mobile terminal 100 or an application program being executed.

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.

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.

2 is a perspective view showing an example of a watch-type mobile terminal 300 according to another embodiment of the present invention.

2, a watch-type mobile terminal 300 includes a main body 301 having a display unit 351 and a band 302 connected to the main body 301 and configured to be worn on the wrist. In general, mobile terminal 300 may include features of mobile terminal 100 of Figure 1 or similar features.

The main body 301 includes a case that forms an appearance. As shown, the case may include a first case 301a and a second case 301b that provide an internal space for accommodating various electronic components. However, the present invention is not limited to this, and one case may be configured to provide the internal space, so that a mobile terminal 300 of a unibody may be realized.

The watch-type mobile terminal 300 is configured to allow wireless communication, and the main body 301 may be provided with an antenna for the wireless communication. On the other hand, the antenna can expand its performance by using a case. For example, a case including a conductive material may be configured to electrically connect with the antenna to extend the ground or radiating area.

A display unit 351 is disposed on a front surface of the main body 301 to output information, and a touch sensor is provided on the display unit 351 to implement a touch screen. The window 351a of the display unit 351 may be mounted on the first case 301a to form a front surface of the terminal body together with the first case 301a.

The main body 301 may include an acoustic output unit 352, a camera 321, a microphone 322, a user input unit 323, and the like. When the display unit 351 is implemented as a touch screen, the display unit 351 may function as a user input unit 323, so that the main body 301 may not have a separate key.

The band 302 is worn on the wrist so as to surround the wrist and can be formed of a flexible material for easy wearing.

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.

3 is a flowchart illustrating a method of controlling a mobile terminal according to an exemplary embodiment of the present invention. 4A to 7B are views for explaining a preview image in the photographing direction of the camera changed according to the rotation of the mobile terminal according to the 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. Hereinafter, a method of controlling a mobile terminal according to an exemplary embodiment of the present invention and an operation of the mobile terminal 100 for implementing the method will be described in detail with reference to the accompanying drawings.

Referring to FIG. 3, the sensing unit 140 may sense the rotation of the watch type mobile terminal 100 (S100).

The watch-type mobile terminal 100 may be worn on the user's body. The rotation may mean that the mobile terminal 100 is rotated while being worn on the user's body (e.g., the wrist). However, the present invention is not limited to this, and if the mobile terminal 100 rotates, the following features may be practically the same unless otherwise specified.

1, the sensing unit 140 may include an acceleration sensor, a magnetic sensor, a gravity sensor, a gyroscope sensor, and the like. The sensing unit 140 may sense the rotation of the mobile terminal 100 in the body of the user using the sensors. Any method can be applied as long as the sensing unit 140 can detect the rotation of the mobile terminal 100, and the present invention is not limited to the specific method. The sensing unit 140 may transmit information about the rotation of the mobile terminal 100 to the controller 180.

Referring back to FIG. 3, the control unit 180 can confirm the photographing direction of the changed camera according to the detected rotation (S110).

According to one example, the camera 121 may be provided in the band portion of the mobile terminal 100, as shown in FIG. When the mobile terminal 100 is rotated while being worn on the user's wrist, the camera 121 rotates together. The control unit 180 can confirm the state of the user of the mobile terminal 100 according to the rotation based on the received information about the rotation of the mobile terminal 100. [ Based on the worn state, the control unit 180 can acquire the photographing direction of the camera 121 rotated according to the rotation of the mobile terminal 100. [

5A, in a state in which the mobile terminal 100 is worn so that the user a can recognize the touch screen 151, the photographing direction of the camera 121 may be the front of the user a. 6A, the photographing direction of the camera 121 may be downward while the mobile terminal 100 is rotated so that the user a can photograph the object Q1 placed below. 7A, the photographing direction of the camera 121 may be the direction of the user (a) in a state in which the mobile terminal 100 is rotated so that the user a can photograph his or her own image.

Referring back to FIG. 3, the controller 180 may acquire a preview image of the identified photographing direction through the camera [S120]. The control unit 180 may display the obtained preview image on the touch screen (S130).

The control unit 180 may display a preview image of the photographing direction of the camera, which is changed according to the rotation of the mobile terminal 100, on the touch screen 151. [ According to an example, in a state in which the camera 121 is driven, the control unit 180 can continuously change the preview image according to the rotation of the mobile terminal 100. According to another example, when the mobile terminal 100 is rotated, the controller 180 may drive the camera 121 to display a preview image.

5B shows a state in which the mobile terminal 100 is worn from above when the photographing direction of the camera 121 is forward of the user a. Referring to FIG. 5B, the touch screen 151 is positioned toward the back of the user a. Therefore, the camera 121 faces upward in Fig. 5B, that is, toward the front of the user (a).

In this case, the preview image 20 displayed on the touch screen 151 may be an image of a forward object. According to an example, the control unit 180 may display the image capture indicator 10 on the touch screen 151. [ Upon receiving the input to select the image capture indicator 10, the control unit 180 may capture the preview image 20 and store the captured image in the memory 170.

6B shows a state in which the mobile terminal 100 is worn down from above when the photographing direction of the camera 121 is downward. Referring to FIG. 6B, the touch screen 151 is positioned toward the front of the user a. Therefore, the camera 121 is directed downward, which is the palm direction of the user (a).

In this case, the preview image 21 displayed on the touch screen 151 may be an image for the downward object. According to one example, the QR code Q1 is shown below the camera 121 in FIG. 6A. The control unit 180 may display the QR code Q1 sensed through the camera 121 on the touch screen 151. [ According to an example, when the control unit 180 determines that the preview image 21 includes the QR code Q1, it may execute an application for scanning the QR code Q1.

7B shows a state in which the mobile terminal 100 is worn when viewed from above when the camera 121 is in the direction of the user (a). Referring to FIG. 7B, the touch screen 151 is positioned toward the palm side of the user (a). Therefore, the camera 121 faces downward in Fig. 7B, that is, toward the user a. In this case, the preview image 22 displayed on the touch screen 151 may be an image for the user a.

Referring back to FIG. 3, the controller 180 may correct the preview image according to a reference set to correspond to the identified photographing direction (S140).

The control unit 180 can correct the preview images 20, 21, and 22 according to different standards for the case where the camera 121 is in the forward direction, the downward direction, or the user direction. According to an example, the set reference may include a reference value for the angle of view, brightness, saturation, contrast, or sharpness of the preview images 20, 21, However, the present invention is not limited thereto. The set reference may include a reference value for other characteristics as long as it is a characteristic for photographing an image.

For example, it is assumed that the photographing direction of the camera 121 is forward of the user. In this case, the brightness of the preview image 20 with respect to the front may be adjusted to a preset reference value to correspond to the case where the photographing direction is ahead of the user. That is, when the photographing direction is confirmed to be forward of the user, the controller 180 may control the camera 121 to adjust the brightness of the preview image 20 according to the brightness set corresponding to the front of the user. Accordingly, the user can shoot an image having a preset brightness even if the user does not check the touch screen 151.

It is assumed that the photographing direction of the camera 121 is forward of the user in relation to the correction of the preview image. However, this is not limitative. The above description can be applied to substantially the same with respect to other photographing directions of the camera 121. [

According to an example, the set criteria may be set by the user. The control unit 180 may display a screen on the touch screen 151 in which the reference can be set according to the rotation direction of the camera 121. [ Accordingly, the user can set the shooting angle, brightness, saturation, contrast, sharpness, or the like to a desired value for each shooting direction of the camera 121. [

According to another example, the set reference may be set according to a photographing pattern of the user. It is assumed that a plurality of images photographed through the camera 121 are stored in the memory 170 of the mobile terminal 100. The control unit 180 may acquire a common feature from the images taken in the same photographing direction among the plurality of images.

For example, the control unit 180 may classify images of the plurality of images when the shooting direction of the camera 121 is the user direction. For this purpose, the controller 180 may classify the images including the information that the photographing direction of the camera 121 is the user's direction among the plurality of images. Alternatively, the control unit 180 may classify the image including the user a among the plurality of images using the object recognition technology.

Thereafter, the control unit 180 may acquire features applied at the time of shooting in the images in the user direction. The obtained feature may be a photographing pattern such as a photographing angle, brightness or saturation of the image, and the like applied when photographing images in the user direction. The control unit 180 may acquire a common feature in the acquired features.

In this case, the characteristic of the image of a certain ratio or more among the images in the user direction may be stored in the memory 170 based on the set reference. For example, if the feature is acquired in 50% or more of the images in the user direction, it may be stored as the set reference. The above 50% is an example, and may be set differently as needed.

It is assumed that the photographing direction of the camera 121 is the user direction with respect to the set reference. However, the present invention is not limited thereto. The above description can be applied to substantially the same with respect to other photographing directions of the camera 121. [

According to an example, when the preview image 20, 21, 22 is photographed by being corrected differently from the set reference, the control unit 180 may update the set reference based on the photographed image. The user can correct the preview image 20, 21, 22 corrected by the control unit 180 by adjusting the characteristics of the camera 121. [

For example, in a case where the brightness of the preview image 20 is adjusted according to the set reference, the user can control the camera 121 to adjust the brightness to a different brightness and take an image. The control unit 180 can check whether the photographed images are corrected to have a brightness different from the set reference to be equal to or greater than the predetermined ratio. It is assumed that the images photographed with the different brightness are above the predetermined ratio. In this case, the control unit 180 may update the brightness included in the set criteria to the different brightness and store the brightness.

According to this, the preview image corrected based on the photographing direction of the camera 121 changed in accordance with the rotation of the watch-type mobile terminal 100 can be provided. Further, by correcting the preview image based on a plurality of images photographed in the same photographing direction, it is possible to photograph an image according to the characteristics mainly photographed by the user without confirming the preview image. Further, by updating the reference for correcting the preview image upon image capturing, it is possible to take an image according to a criterion mainly applied recently.

FIGS. 8A and 8B are diagrams for explaining outputting of an alarm to guide a preview image according to an embodiment of the present invention to a preset photographing angle. FIG.

The control unit 180 may output an alarm that guides the preview image to be positioned at the shooting angle included in the set reference when the mobile terminal 100 moves. Referring to FIG. 8A, when the photographing direction of the camera 121 is the front of the user, the photographing angle R1 included in the set reference is shown.

As described above, the photographing angle R1 may be an angle mainly photographed by the user when the photographing direction of the camera 121 is the front of the user. The control unit 180 may determine whether the mobile terminal 100 is located at the photographing angle R1 based on the movement of the mobile terminal 100 detected by the sensing unit 140. [

The control unit 180 may output an alarm through the output unit 150 when the mobile terminal 100 is not expanded to the photographing angle R1 as shown in FIG. For example, the alarm may be an output of vibration through the haptic module 153. Alternatively, the alarm may be an output of sound through the sound output unit 152. In this case, the controller 180 may output a voice alarm including information on the progress direction.

8B, the control unit 180 may output an alarm through the output unit 150 when the mobile terminal 100 is further expanded than the photographing angle R1. In this case, the alarm may be an output of vibration different from the vibration in FIG. 8A. Alternatively, the alarm may be an output of sound different from the sound in Fig. 8A. In this case, the controller 180 may output a voice alarm including information on the progress direction.

It is assumed that the photographing direction of the camera 121 is forward of the user in relation to the output of the alarm for the photographing angle, but this is not limitative. The above description can be applied to substantially the same with respect to other photographing directions of the camera 121. [

According to this, by outputting an alarm that guides the preview image to be set at a predetermined shooting angle, the user can shoot the image according to the appropriate shooting angle without checking the preview image.

FIGS. 9A and 9B are views for explaining deletion of a photographed image at a preset location according to an embodiment of the present invention when the user leaves the preset location.

9A, the preview image 23 obtained in the parking lot is shown in a state in which the photographing direction of the camera 121 is in front of the user. When the user photographs the preview image 23, the control unit 180 can receive the location information of the mobile terminal 100 through the location information module 115 of the wireless communication unit 110. However, this is an example, and the positional information can be received in advance regardless of the photographing of the image.

The control unit 180 may determine whether the received location information is a preset location. The predetermined place may include a place where an image for recording information is mainly photographed in the nature of the place. For example, a place where an image is taken to memorize the position where the car is parked, such as a parking lot, may correspond to the predetermined place.

The control unit 180 may determine whether the text t1 is recognized in the photographed image when the location of the mobile terminal 100 is the predetermined location. If the text t1 is recognized, the control unit 180 may store the text t1. According to one example, the control unit 180 may execute a memo application to store the text t1.

The control unit 180 can display the preset place 31, the recognized text 32, or the information 33 such as the received position and time on the execution screen 30 of the memo application, as shown in Fig. 9B. According to an example, the control unit 180 can associate and store the photographed image and the execution screen 30. When the specific touch input is applied to the execution screen 30, the controller 180 may display the photographed image on the touch screen 151. Alternatively, if a specific touch input is applied to the photographed image, the control unit 180 may display the execution screen 30 on the touch screen 151. [

Thereafter, when the mobile terminal 100 moves out of the preset location, the control unit 180 may remove the photographed image from the memory 170. [ According to an example, the control unit 180 may not delete the contents stored in the execution screen 30 of the memo application. However, the present invention is not limited to this, and the contents stored in the execution screen 30 may be preset to be deleted.

According to another example, the control unit 180 may output an alarm notifying the user before deleting the photographed image. In this case, the control unit 180 may display a screen on the touch screen 151 to select whether or not to delete the photographed image.

According to an example, even when there is another external device set to transmit the photographed image, the control unit 180 may not transmit the photographed image to the external device at the preset location. This is to prevent unnecessary transmission because the image photographed at the preset location is set to be deleted when the user leaves the preset location.

According to the present invention, when an image photographed at a predetermined place satisfies a specific condition, the photographed image is deleted when the user leaves the preset place, thereby effectively managing the capacity of the memory.

FIGS. 10A and 10B are diagrams for explaining deletion of an image photographed at a predetermined angle according to an embodiment of the present invention, based on text included in the image. FIG.

Referring to FIG. 10A, a preview image 24 including an object inclined by a predetermined angle or more is shown in a state in which the photographing direction of the camera 121 is in front of the user. The user can photograph the specific object in a state of being tilted by a predetermined angle or more in order to capture an image for recording information of the specific object. For example, as shown in FIG. 10A, when the specific object is a performance poster including the text t2, the user can photograph the performance poster with a predetermined angle or more.

The control unit 180 may determine whether the photographed specific object is in a state inclined by a predetermined angle or more. According to an example, the predetermined angle may be set to be larger than an angle that can be tilted by hand trembling or the like when a specific object is photographed. However, this is an example, and the predetermined angle may be set to another value as needed.

The control unit 180 may determine whether the text t2 is recognized in the photographed image when the photographed specific object is inclined by a predetermined angle or more. If the text t2 is recognized, the controller 180 may store the text t2. According to one example, the control unit 180 may execute the memo application to store the text t2.

The control unit 180 may display information 35, 36, 37 on the text t2 included in the specific object on the execution screen 34 of the memo application, as shown in FIG. 10B. According to an example, the control unit 180 may associate the captured image with the execution screen 34 and store the combined image. When the specific touch input is applied to the execution screen 34, the controller 180 may display the photographed image on the touch screen 151. Alternatively, when a specific touch input is applied to the photographed image, the control unit 180 may display the execution screen 34 on the touch screen 151. [

According to an example, the controller 180 may extract the time information 36 from the text t2 included in the photographed object. For this purpose, known text recognition techniques may be applied. The control unit 180 may remove the photographed image from the memory 170 after a time indicated in the extracted time information 36. [ According to an example, the control unit 180 may not delete the contents stored in the execution screen 34 of the memo application. However, the present invention is not limited to this, and the contents stored in the execution screen 34 may be preset to be deleted.

According to another example, the control unit 180 may output an alarm notifying the user before deleting the photographed image. In this case, the control unit 180 may display a screen on the touch screen 151 to select whether or not to delete the photographed image.

According to an example, even when there is another external device set to transmit the photographed image, the control unit 180 may not transmit the photographed image in the state tilted by the predetermined angle or more to the external device. This is because the image photographed in a state inclined by the predetermined angle is set to be deleted when the specific condition is satisfied, so that unnecessary transfer is prevented.

According to the present invention, the memory capacity can be effectively managed by deleting the photographed image when a predetermined time has elapsed based on the recognized text, in a case where a text inclined by a predetermined angle or more is recognized in the photographed image .

11A and 11B are diagrams for explaining correction of a text included in a preview image in a state in which the photographing direction of the camera is downward according to an embodiment of the present invention.
