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 or absence of an object approaching a predetermined detection surface or an object present in the vicinity without using a mechanical contact by using an electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in an inner region of the mobile terminal covered by the touch screen described above or near the touch screen.

Examples of the proximity sensor 141 include a transmission photoelectric sensor, a direct reflection photoelectric sensor, a mirror reflection photoelectric sensor, a high frequency oscillation proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is capacitive, the proximity sensor 141 may be configured to detect the proximity of the object by the change of the electric field according to the proximity of the conductive object. 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, an action of allowing the object to be recognized without being in contact with the touch screen so that the object is located on the touch screen is referred to as a "proximity touch", and the touch The act of actually touching an object on a screen is called a "contact touch." The position at which the object is in close proximity touch on the touch screen means a position where the object is perpendicular to the touch screen when the object is in close proximity touch.

Here, the touch object is an object applying a touch to the touch sensor and may be, for example, a finger, a touch pen or a stylus pen, a pointer, or the like.

As such, 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 then transmits the corresponding data to the controller 180. As a result, the controller 180 can know which area of the display unit 151 is touched. Here, the touch controller may be a separate component from the controller 180 or may be the controller 180 itself.

The photo sensor may be stacked on the display element, which is configured to scan the movement of the sensing object in proximity to the touch screen. More specifically, the photo sensor mounts a photo diode and a transistor (TR) in a row / column and scans contents mounted on the photo sensor by using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor calculates coordinates of the sensing object according to the amount of light change, and thus, the position information of the sensing object can be obtained.

To illustrate. When the battery 191 is detachably configured to the terminal body, the rear cover 103 may be detachably coupled to the rear case 102.

An accessory may be added to the mobile terminal 100 to protect the appearance or to assist or expand the function of the mobile terminal 100. An example of such an accessory may be a cover or pouch that covers or accommodates at least one surface of the mobile terminal 100. The cover or pouch may be configured to be linked with the display unit 151 to expand the function of the mobile terminal 100. Another example of the accessory may be a touch pen for assisting or extending a touch input to a touch screen.

An accessory may be added to the mobile terminal 100 to protect the appearance or to assist or expand the function of the mobile terminal 100. An example of such an accessory is a camera 230 that can be used in conjunction with a terminal body. The camera 230 may be formed separately from the terminal body to overcome the spatial constraints of the

cameras

121a and 121b embedded in the terminal body itself.

Meanwhile, the present invention provides a mobile terminal for photographing a subject at more various angles and distances by using the camera 230. Meanwhile, the camera 230 may be provided in the camera module 200. Hereinafter, the camera module 200 will be described based on the accompanying drawings.

2A is a perspective view of the camera module 200 related to the present invention, and FIG. 2B is an exploded perspective view of the camera module 200.

As shown, the camera module 200 according to the present invention includes a main body 210, an auxiliary body 220, and a camera 230. Hereinafter, each component will be described in detail.

Referring to Figure 2a, the appearance of the body 210 is made of a generally spherical case. The camera 230 is built into the case of the main body 210.

In addition, an incident surface 231 of the camera is formed on a case of the main body 210 to allow external light to enter the camera 230. The incident surface 231 of the camera may be formed of the lens itself or a protective glass that protects the lens.

The auxiliary body 220 is formed to be at least partially mounted to the main body 210. Although not shown in the drawings, the auxiliary body 220 includes a protrusion and the main body 210 has a groove, and thus, the auxiliary body 220 may be mounted on the main body 210 by combining them.

On the other hand, the surface disposed opposite to the surface on which the main body 210 of the auxiliary body 220 is mounted may include an attachment portion 2211. Therefore, the camera module 200 may be attached to a wall or an external structure through the attachment part 2211.

Alternatively, at least a part of the case of the main body 210 is made of a magnetic material such as iron, and the auxiliary body 220 includes a magnet, and the auxiliary body 220 is connected to the main body 210 through the attraction force of the magnetic body and the magnet. It is also possible to be mounted.

In addition, the auxiliary body 220 may be formed to be rotatable on the main body 210. As the auxiliary body 220 rotates on the main body 210, the photographing angle of the camera 230 may be adjusted.

On the other hand, in the drawing shows a cylindrical body of the cylindrical shape, one side is opened and closed so that the spherical body 210 can be mounted, the shape of the body 210 and the auxiliary body 220 is the sphere and the auxiliary body ( 220).

The camera 230 includes a plurality of lenses, an aperture, a shutter plate, an image sensor, and the like (not shown) to image an external subject. The detailed components of each camera 230 are controlled by the controller 180. For example, when an input signal for adjusting the number of frames is applied, the controller 180 adjusts a driving speed of a shutter plate (not shown) of the camera 230.

In addition, the camera 230 includes a wireless communication unit 241 for wireless connection with the terminal body. The wireless communication unit 240 includes a short range communication module 241. The short range communication module 241 is for short range communication, and includes Bluetooth ™, Radio Frequency Identification (RFID), Infrared Data Association (IrDA), Ultra Wideband (UWB), ZigBee, and NFC. (Near Field Communication), at least one of Wi-Fi (Wireless-Fidelity), Wi-Fi Direct, Wireless USB (Wireless Universal Serial Bus) technology can be used to support short-range communication.

Meanwhile, the preview image photographed by the camera 230 may be transmitted to the terminal body through the wireless communication unit 240. Hereinafter, with reference to the accompanying drawings, it will be described in detail with respect to the camera shooting control through the terminal body.

3 is a flowchart illustrating a camera photography control method according to the present invention, and FIGS. 4A to 4D are conceptual views illustrating the control method of FIG. 3.

Referring to FIGS. 3 and 4A together, the display unit 151 formed on the terminal body may output a preview image received from the camera 230 (S310). Accordingly, the user may check in advance the composition of the subject in the image to be photographed by the camera 230 while looking at the preview image displayed on the display unit 151 (see D1 direction).

3 and 4A (b) together, the controller 180 specifies the

subjects

300a, 300b, and 300c included in the preview image (S320). Here, the subject may mean a person or an object to be photographed. Also, the subject may be singular or plural.

In detail, the controller 180 may specify a subject included in the preview image based on a preset method. The preset method may recognize a person or an object by using contour information or color information of a person or an object that is distinguished from other areas in the image.

For example, the preset method may be a preset face recognition algorithm. The face recognition algorithm recognizes a face of a subject through a ratio of distances of eyes, nose, and mouth, which are main parts of the face.

In addition to the preset method, the controller 180 may specify the subject based on the touch input sensed on the display unit 151.

For example, when a user's touch input is detected on the display unit 151, the controller 180 may specify a subject corresponding to the graphic object included in the trace of the detected touch input.

In other words, the controller 180 may specify the subject by at least one of a preset method and a user's touch input.

For example, referring to FIG. 4B, the controller 180 specifies the face 300d of the subject as a photographing target based on the preset face recognition algorithm. At the same time, the user may add the object to be photographed by applying the touch input 300e to an object other than a face.

In addition, the display unit 151 may output information informing the specified subject on the preview image. Specifically, the information is a line displayed on the corresponding graphic object of the specified subject, and may be displayed by being superimposed on the graphic object. Thus, the user may once again confirm the subject to be photographed through the information.

On the other hand, when the specification of the subject to be photographed is completed, the controller 180 controls control of capturing an image received through the camera in response to sensing of a preset movement M1 of the user through the sensing unit 140. Perform Hereinafter, this will be described in detail.

The mobile terminal according to the present invention includes a sensing unit 140. The sensing unit 140 detects a motion M1 of the user holding the mobile terminal 100 using a motion sensor or the like.

Referring to (a) and (b) of FIG. 4C, in detail, the preset motion M1 of the user may be a motion of lowering an arm or a hand. For example, the user may take a picture in an intuitive and simple manner while looking at the camera 200 without staring at the display unit 151 (see FIG. 4C (a)).

Meanwhile, the preset user movement M1 may be any movement that the user intends to start shooting, such as a movement of lifting his / her face by lifting his / her head or hand.

In addition, the sensing unit 140 may include at least one of an acceleration sensor, a magnetic sensor, a gravity sensor, and a gyroscope sensor. In this case, the movement M1 of the user may be a movement of the user corresponding to the movement of the main body descending above a preset speed.

As described above, the controller 180 performs control related to capturing an image received through the camera in response to sensing of a preset movement M1 of the user through the sensing unit 140.

In detail, when a preset movement M1 of the user is sensed, the controller 180 determines whether the specified subject is included in the image received from the camera 230 after the sensing (S340).

Furthermore, the controller 180 stores the image in the memory 170 or outputs notification information indicating that the specified subject is not included in the image, depending on whether the content is included. Meanwhile, the image received from the camera 230 after the sensing may not be output to the display unit 151.

Referring to FIG. 3 again, when the controller 180 determines that the specified subject is included in the image, the controller 180 stores the image in the memory 170 and does not output notification information (S350).

The image stored in the memory 170 may be an image received from the camera 230 at the time of sensing the user's motion M1 or may be preset from the time of sensing the user's motion M1. It may be an image received from the camera 230 after time.

3 and 4D, when the controller 180 determines that at least some of the specified

subjects

300a, 300b, and 300c are not included in the image, the image is not stored in the memory 170. In operation S360, the notification information is output.

In addition, the notification information may be output as one of voice or vibration. The user may recognize that there is a subject that is not included in the image among the specified subjects through the notification information. Furthermore, the user may recognize the necessity of changing the position or the composition so that all of the subject intended to be photographed by the user is included in the image.

As described above, the controller 180 performs different control related to image capturing based on whether a specific subject is included in the image after sensing the user's movement M1.

Further, the controller 180 may perform different control related to image capturing based on whether at least a part of the specified subject is out of the reference area 400 set on the display unit 151 in the image. can do. In order to explain this, first, the reference area 400 will be described in detail.

5A is a conceptual diagram illustrating setting of a reference region according to the present invention, and FIG. 5B is a conceptual diagram illustrating a photographing control method of a camera using the reference region according to the present invention.

The controller 180 may set a reference area on the display unit 151. The set reference area may have a preset size and shape on the display unit 151 when the

subjects

300a, 300b, and 300c are to be photographed, and may be displayed at a preset position. However, the reference area may not be displayed on the display unit 151.

In detail, referring to FIG. 5A, the controller 180 may set the reference area based on a touch input sensed on the display unit 151.

For example, referring to FIG. 5A (a), the controller 180 may display

graphic objects

400a, 400b, and 400c corresponding to reference areas of various sizes on the display unit 151. As illustrated in (b) of FIG. 5A, when a user's touch input is detected, the controller 180 may set a reference area to correspond to the graphic object 400a at the position of the detected touch input. As illustrated in (c) of FIG. 5A, when the reference area is set, the controller 180 displays only the graphic object 400a corresponding to the set reference area on the display unit 151, and the rest is no longer displayed. It may not be displayed on the unit 151. Thus, the user can once again check the set reference area.

Meanwhile, the setting of the reference area may occur at the same time when the specification of the subject to be photographed occurs. Alternatively, the setting of the reference area may occur once, and the set reference area may be stored on the memory 170. In this case, the stored reference area may be used without needing to set the reference area every time the specification of the subject to be photographed occurs.

According to an embodiment of the present invention, different types of notification information are output according to a direction in which the specified subject is out of the preset reference area.

In more detail, the different types of notification information may relate to a moving direction related to a location or composition to be changed by the user. Hereinafter, with reference to FIG. 5B, the case in which the notification information is in the form of vibration will be described in detail.

The mobile terminal according to an embodiment of the present invention further includes a haptic module 153 for generating vibration. In detail, the haptic module 153 may generate vibration in any one of a plurality of vibration patterns.

For example, the plurality of vibration patterns may be first to fourth vibration patterns. Specifically, each of the first to fourth vibration patterns may be a vibration pattern corresponding to an upper side, a lower side, a left side, and a right side with respect to the front surface of the main body of the mobile terminal.

Referring to FIG. 5B, notification information having one vibration pattern among the first to fourth vibration patterns may be output based on a direction in which the specified subject is out of the preset reference area.

Referring to (a) of FIG. 5B, when at least a part of a specified subject is deviated toward the first corner 410 of the reference area, the haptic module 153 generates vibrations according to the first vibration pattern 510. You can. In other words, when at least a part of the specified subject intersects the upper edge of the reference area, the haptic module 153 generates vibration in a vibration pattern corresponding to the upper direction.

Referring to (b) of FIG. 5B, when at least a part of the specified subject deviates toward the second corner 420 of the reference area, the haptic module 153 generates vibrations according to the second vibration pattern 520. You can. In other words, when at least a part of the specified subject intersects the lower edge of the reference area, the haptic module 153 generates vibration in a vibration pattern corresponding to the lower direction.

Referring to (c) of FIG. 5B, when at least a part of the specified subject deviates toward the third corner 430 of the reference area, the haptic module 153 generates vibrations according to the third vibration pattern 530. You can. In other words, when at least a part of the specified subject intersects the left edge of the reference area, the haptic module 153 generates vibration in a vibration pattern corresponding to the left direction.

Although not shown, if at least a part of the specified subject deviates toward the fourth corner 440 of the reference area, the haptic module 153 may generate vibrations according to the fourth vibration pattern 540. In other words, when at least a part of the specified subject intersects the right edge of the reference area, the haptic module 153 generates vibration in a vibration pattern corresponding to the right direction.

In addition, referring to FIG. 5B (d), if at least some of the specified subjects deviate toward the first and

fourth corners

410 and 440 of the reference area, the haptic module 153 may include the first and the first. The vibrations according to the four

vibration patterns

510 and 540 may be simultaneously generated. In other words, if at least some of the specified subjects intersect the first and

fourth edges

410 and 440, the vibrations according to the first and

fourth vibration patterns

510 and 540 may occur all at once or sequentially. have.

Accordingly, the user may recognize the direction deviating from the reference area through the vibration pattern felt by the tactile sense without having to check the display unit 151 again.

The controller 180 may change the intensity of vibration based on the degree to which the specified subject deviates from the reference area. Hereinafter, this will be described in detail with reference to FIG. 5C.

5C is a conceptual diagram related to a control method of changing the intensity of vibration based on the degree to which a specified subject deviates from the reference region.

For example, FIGS. 5C and 5C both show the case where the specified subject intersects the same edge 440 of the reference area.

First, referring to FIG. 5C (a), when the degree to which the specified subject deviates from the reference area is greater than or equal to a preset range, the controller 180 strongly adjusts the intensity of vibration.

The extent to which the specified subject deviates from the reference area in FIG. 5C (b) is smaller than that in FIG. 5C (a). Therefore, in this case, the intensity of vibration is adjusted to be weaker than that of Fig. 5C.

Accordingly, the user may recognize the degree of deviation from the reference area through the sensed vibration intensity without having to check the display unit 151 again.

As described above, the controller 180 may notify the user of the direction and degree to which the specified subject deviates from the reference area by adjusting the pattern and intensity of the vibration generated by the haptic module 153. In the meantime, the case in which the notification information is a vibration form has been described in detail, but the notification information may be in various forms such as a voice and a flash form.

Accordingly, the user may receive information about the direction and distance to be moved through the notification information and move to include all of the specified subjects in the image without looking at the display unit 151.

By the movement, the subject may be included in the image received from the camera after the notification information is output, which will be described in detail below.

6A and 6B are flowcharts illustrating a camera photography control method according to the present invention. 7A to 7C are conceptual views illustrating the control method of FIGS. 6A and 6B.

Meanwhile, since two different types of preset user motions are mentioned below, the above-described user motions are hereinafter referred to as first user motions M1, and the new user motions appearing in the future are second user motions M2. This is called.

As described above, referring to (a) of FIGS. 6A and 7A, the controller 180 corresponds to sensing the movement M1 of the first user by the sensing unit 140, and the image received through the camera. If the specified subject is not included, notification information is output (S360).

Referring to FIG. 7A (b), the subject may move based on the vibration pattern of the notification information.

Referring to FIG. 6A, after the notification information is output, the controller determines once again whether the subject specified in the image received from the camera is included (S361).

In response to the movement, when the entirety of the specified subject is included in the image received from the camera, the output of the notification information is stopped and the image is stored in the memory 170 (S362).

Referring to FIG. 7A (c), when the sensing unit 140 senses a preset movement of the second user M2, the display unit 151 outputs the stored image. Control (S364).

Here, the preset movement M2 of the second user may be a movement of raising an arm or a hand. Meanwhile, the preset second user's motion M2 may be any motion that the user takes to stare again without staring at the terminal body, such as a motion of raising or lowering his / her head or hand. have.

In addition, the movement M2 of the second user may be a movement of a preset body detected by the sensing unit 140. In detail, the movement of the preset body may be a movement in which the main body rises above a preset speed.

Subsequently, referring to FIG. 7A (c), the display unit 151 may output a virtual icon related to maintaining the stored image along with the stored image. Specifically, the controller 180 maintains the storage of the image when the user touches the icon labeled 'save', and immediately deletes the image when the user touches the icon marked 'delete'.

Accordingly, the user can immediately check the image stored after the notification information is output at least once and determine whether or not to delete it, thereby enabling efficient photo album management.

On the other hand, despite the notification information output, even if the user does not move or move, there may occur a case that the subject is still not included in the image received from the camera after the notification information output.

In this case, referring to (a) and (b) of FIG. 7B, the controller 180 stops outputting the notification information when the preset movement of the second user M2 is sensed through the sensing unit 140. (S363). Further, the controller 180 outputs guide information for inducing a change in the position of the specified subject to the display unit 151 (S365).

The guide information may be information about a direction and a distance to which a specified subject should move. Specifically, the guide information may be information about a direction and a distance to which the specified subject should move so that all of the specified subject may be included in the image.

For example, referring to (b) of FIG. 7B, when a right portion of the specified subject is out of the image, a movement direction indication to move to the left may be output.

Although not shown, the controller 180 may change the position with the help of the guide information and output the 'OK' on the display unit 151 when all of them are included in the image. .

6B and 7C, if the controller 180 does not output the notification information (S350), when the second user's movement M2 is detected through the sensor unit (S351), the display unit 151 In operation S352, the preview image may be output for the next shooting.

In other words, if the notification information has not been output at all, the user has a high probability of taking a picture according to the user's intention, so that the user can quickly prepare to take the next image without checking the stored picture.

8 is a flowchart illustrating a camera photography control method according to another exemplary embodiment related to the present invention. FIG. 9 is a conceptual diagram illustrating the control method of FIG. 8.

8 and 9A, the controller 180 outputs a preview image received from a camera to the display unit 151. In addition, the controller 180 specifies a subject to be photographed in the preview image (S810). As described above, the controller 180 may specify a subject to be photographed based on a preset face recognition algorithm.

8 and 9 (b), the sensing unit 140 senses the movement M1 of the first user set in operation S820. As described above, the preset motion M1 of the first user may be a motion of lowering a hand holding the terminal from top to bottom.

Although not illustrated, as described above, when the image received from the camera includes the specified subject in response to sensing of the motion M1 of the first user, the image is stored and not included. If not, the notification information may be output.

Subsequently, referring to FIGS. 8 and 9 (c), when a subject other than a predetermined subject enters the photographing area of the camera, the controller 180 may detect the motion after the first user's movement M1. The other subject may be recognized in the image received from the camera (S830). In detail, the controller 180 recognizes the other subject based on a preset face recognition algorithm.

8 and 9 (d), the sensing unit 140 senses the movement M2 of the preset second user (S840). As described above, the preset movement M2 of the second user may be a movement of raising the hand holding the terminal from the bottom up.

In this case, the controller 180 controls the display unit 151 to output a preview image for the next shooting (S850). Accordingly, the user may prepare to take a photograph again by holding the subjects including the added subject, a photographing composition, and the like, without looking at the preview image.

So far, the camera related to the present invention has been described with reference to the camera 230 formed separately from the terminal body, but it is apparent that the

cameras

121a and 121b embedded in the terminal body itself may be used.

The present invention described above can be embodied as computer readable codes on a medium in which a program is recorded. The computer-readable medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of computer-readable media include hard disk drives (HDDs), solid state disks (SSDs), silicon disk drives (SDDs), ROMs, RAMs, CD-ROMs, magnetic tapes, floppy disks, optical data storage devices, and the like. This also includes implementations in the form of carrier waves (eg, transmission over the Internet). In addition, the computer may include the controller 180 of the terminal. Accordingly, the above detailed description should not be construed as limiting in all aspects and should be considered as illustrative. The scope of the invention should be determined by reasonable interpretation of the appended claims, and all changes within the equivalent scope of the invention are included in the scope of the invention.
