The rear structure of the display unit 151 may also be of a light transmission type. With this structure, the user can see the object located behind the terminal body through the area occupied by the display unit 151 of the terminal body.

There may be two or more display units 151 according to the embodiment of the mobile terminal 100. For example, in the mobile terminal 100, a plurality of display portions may be spaced apart from one another or may be disposed integrally with each other, or may be disposed on different surfaces.

Also, the display unit 151 may be configured as a stereoscopic display unit 152 for displaying a stereoscopic image.

Here, a stereoscopic image represents a 3-dimensional stereoscopic image, and a 3-dimensional stereoscopic image represents a progressive depth and reality in which objects are located on a monitor or a screen, It is an image that makes you feel the same as the space. 3D stereoscopic images are implemented using binocular disparity. The binocular parallax means a parallax caused by the position of two eyes away from each other. When two eyes see two different images and the images are transmitted to the brain through the retina and fused, the depth and real feeling of the stereoscopic image can be felt .

The stereoscopic display unit 152 may be applied to a three-dimensional display system such as a stereoscopic system (glasses system), an autostereoscopic system (no-glasses system), and a projection system (holographic system).

In addition, the 3D thumbnail image can generate a left image thumbnail and a right image thumbnail from the left image and right image of the original image frame, respectively, and combine them to generate one 3D thumbnail image. In general, a thumbnail means a reduced image or a reduced still image. The left image thumbnail and the right image thumbnail generated in this way are displayed on the screen with a difference of the left and right distance by the depth corresponding to the parallax between the left image and the right image, thereby exhibiting a stereoscopic spatial feeling.

The left and right images necessary for realizing the three-dimensional stereoscopic image can be displayed on the stereoscopic display unit 152 by a stereoscopic processing unit (not shown). The stereoscopic processing unit receives a 3D image and extracts a left image and a right image from the 3D image, or receives a 2D image and converts it into a left image and a right image.

On the other hand, when a display unit 151 and a sensor (hereinafter, referred to as 'touch sensor') that detects a touch operation form a mutual layer structure (hereinafter referred to as a 'touch screen' It can also be used as an input device in addition to the device. The touch sensor may have the form of, for example, a touch film, a touch sheet, a touch pad, or the like.

The touch sensor may be configured to convert a change in a pressure applied to a specific portion of the display unit 151 or a capacitance generated in a specific portion of the display unit 151 into an electrical input signal. The touch sensor can be configured to detect not only the position and area where the touch object is touched on the touch sensor but also the pressure at the time of touch. 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.

If 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.

Referring to FIG. 1, a proximity sensor 141 may be disposed in an inner region of the mobile terminal or in the vicinity of the touch screen, which is surrounded by the touch screen. The proximity sensor 141 may be provided as an example of the sensing unit 140. The proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface or an object existing in the vicinity of the detection surface without mechanical contact using an electromagnetic force or an infrared ray. The proximity sensor 141 has a longer life than the contact type sensor and its utilization is also high.

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. When the touch screen is electrostatic, it is configured to detect the proximity of the pointer by a change of the electric field along the proximity of an object having conductivity (hereinafter, referred to as a pointer). In this case, the touch screen (touch sensor) may be classified as a proximity sensor.

Hereinafter, for convenience of explanation, the act of recognizing that the pointer is positioned on the touch screen while the pointer is not in contact with the touch screen is referred to as "proximity touch & The act of actually touching the pointer on the screen is called "contact touch. &Quot; The position where the pointer is proximately touched on the touch screen means a position where the pointer is vertically corresponding to the touch screen when the pointer is touched.

The proximity sensor 141 detects a proximity touch and a proximity touch pattern (for example, a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, a proximity touch movement state, and the like). Information corresponding to the detected proximity touch operation and the proximity touch pattern may be output on the touch screen.

In the case where the three-dimensional display unit 152 and the touch sensor have a mutual layer structure (hereinafter referred to as a 'three-dimensional touch screen') or a three-dimensional sensor that detects the touch operation and the stereoscopic display unit 152 are combined with each other The stereoscopic display unit 152 may also be used as a three-dimensional input device.

The sensing unit 140 may include a proximity sensor 141, a three-dimensional touch sensing unit 142, an ultrasonic sensing unit 143, and a camera sensing unit 144 as an example of the three-dimensional sensor.

The proximity sensor 141 measures the distance between the sensing surface (for example, a user's finger or a stylus pen) to which the touch is applied without mechanical contact using the force of the electromagnetic field or infrared rays. The terminal recognizes which part of the stereoscopic image has been touched using the distance. In particular, when the touch screen is of the electrostatic type, the proximity of the sensing object is detected by a change of the electric field according to the proximity of the sensing object, and the touch on the three-dimensional is recognized using the proximity.

The stereoscopic touch sensing unit 142 senses the strength or duration of a touch applied to the touch screen. For example, the three-dimensional touch sensing unit 142 senses a pressure to apply a touch, and when the pressing force is strong, recognizes the touch as a touch to an object located further away from the touch screen toward the inside of the terminal.

The ultrasonic sensing unit 143 is configured to recognize the position information of the sensing target using ultrasonic waves.

The ultrasound sensing unit 143 may include, for example, an optical sensor and a plurality of ultrasound sensors. The light sensor is configured to sense light, and the ultrasonic sensor is configured to sense ultrasonic waves. Since light is much faster than ultrasonic waves, the time it takes for light to reach the optical sensor is much faster than the time it takes for the ultrasonic waves to reach the ultrasonic sensor. Therefore, it is possible to calculate the position of the wave generating source using the time difference with the time when the ultrasonic wave reaches the reference signal.

The camera sensing unit 144 includes at least one of a camera 121, a photo sensor, and a laser sensor.

For example, the camera 121 and the laser sensor are combined with each other to sense a touch of a sensing target with respect to a three-dimensional stereoscopic image. When the distance information detected by the laser sensor is added to the two-dimensional image photographed by the camera, three-dimensional information can be obtained.

As another example, a photosensor may be stacked on a display element. The photosensor is configured to scan the movement of the object proximate to the touch screen. 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 light change, thereby acquiring position information of the object to be sensed.

The alarm unit 154 may output a signal for notifying the occurrence of an event by using a form other than the video signal or the audio signal, for example, vibration. The video signal or the audio signal may be output through the display unit 151 or the sound output module 153 so that the display unit 151 and the sound output module 153 may be classified as a part of the alarm unit 154 .

The haptic module 155 generates various tactile effects that the user can feel. A typical example of the haptic effect generated by the haptic module 155 may be vibration. The intensity and pattern of the vibration generated by the hit module 155 can be controlled by the user's selection or setting of the control unit. For example, the haptic module 155 may combine and output different vibrations or sequentially output the vibrations.

Generally, in order to capture the sound of a sound source, selective orientation between the sound sources on the horizontal axis or the vertical axis is required on a user basis. In order to provide the selective directivity, a plurality of microphones are arranged orthogonally or crosswise to the back of the mobile terminal, and when only two microphones are used, they are arranged to be spaced apart from each other in the horizontal or vertical linear direction. In particular, the directivity is achieved through signal processing, such as beam-forming, on sounds (e.g., sounds or voices) stuck through a number of microphones. The beam-forming means forming a range in which sound is to be taken into a sound beam to generate a directivity.

The audio zooming technique applied to the present invention is a technique in which a sound of a sound source is acquired through a microphone having the above structure and then audio zooming is applied to selectively record only a desired sound, And a series of operations to reproduce by applying. For example, the user can optimize the audio of the object of interest by automatically adjusting the position and size of the selected or close-up (or focused) object to direct the direction to the position of the object or optimize the range of the sound. Or reproduce.

The present invention provides a method of easily sharing sound information of a specific object (audio object) zoomed in an image with other devices. The sharing of such information is useful when two users are talking or chatting while watching one video.

The video is a video played in a gallery, a video player, or the like.

The image is a stereo image capable of audio zooming, and includes sounds (sound and voice) picked up by a plurality of directional microphones. In addition, the image may include an image stored and applied by the audio zooming technique.

The other device includes a terminal or an external display device (e.g., a TV, a PC, a digital photo frame, and the like) as a device to be connected to the mobile terminal or a device to be shared using wired / wireless communication.

One or a plurality of audio pick-up ranges are displayed on the image.

The audio listening range of each object in the image varies according to a listening mode set by the user, and an indicator indicating an audio listening range is displayed for each listening mode. The chucking mode includes a screen zoom interlocking mode, a key position changing mode, a stereo mode, and a hearing aid mode.

The range of audio stuttering in the image may be in a contact or non-contact manner, such as a user's behavior or gesture on the image. The input by the contact or non-contact method includes a single touch, a multi-touch, a multi-point touch, flicking, and touch & drag.

The audio information obtained by the plurality of microphones in the photographing mode is synthesized with the image information and then compressed and stored in the memory 610. In the reproduction mode, the stored image is separated into audio information and image information, And the sound output module 152, as shown in Fig. Accordingly, in the photographing or reproducing mode, the audio information picked up by the plurality of microphones is directly compressed and stored in the moving picture format after applying the audio zooming technology, and audio zooming technology can be applied to the separated audio information in the reproducing mode will be. The audio zooming method described below has been described by taking the reproduction mode as an example, but the present invention is not limited to this and is also applied to the shooting mode.

3 is an application example of the audio zooming technique in the photographing mode.

3, audio information captured by a plurality of microphones 122 at the time of image capturing is subjected to audio zooming techniques such as beam forming and noise cancellation, Information. The synthesized and generated image is compressed in a predetermined format and then stored in the memory 160. In particular, the unit for processing the beam forming forms a signal processing unit (not shown) together with a unit for performing noise removal as a part for forming a sound beam adaptively according to a sound range and position to generate directivity.

4 is an application example of the audio zooming technique in the reproduction mode.

As shown in FIG. 4, the moving picture stored in the memory 160 is decompressed and separated (restored) into audio information and image information, respectively. The separated audio information is synthesized with the separated image information after the audio zooming technique such as beamforming and noise removal is applied and reproduced. Likewise, the unit for processing the beam forming forms a signal processing unit (not shown) together with a unit for performing noise removal as a part for forming a sound beam adaptively according to a sound range and position to generate directivity.

The audio information that has undergone the compression or decompression process is hardly different from the audio signal directly input to the microphone 122.

If the microphone 122 of the mobile terminal and the arrangement structure of the camera 121 are known, the audio zooming technique may be directly applied to the audio signal input through the microphones 122, or the audio zooming technique may be applied to the stored audio signal The same effect can be obtained.

FIG. 5 is a flowchart illustrating a method of sharing audio-zoomed information of a mobile terminal according to an embodiment of the present invention.

As shown in FIG. 5, the controller 180 reproduces (displays) a stereo image capable of audio zooming through the display unit 151 according to a user's selection (S10).

If the object to be picked up (the specific object) is selected in the reproduced image, the controller 180 receives the audio of the selected object (S12) when the audio zooming command is input (S11). At this time, the audio listening range of the selected object can be appropriately adjusted.

When the audio acquisition for the selected object is performed, the control unit 180 transmits the captured image to the predetermined shared device (step S13). If the shared device to be transmitted is not set, the control unit 180 provides a menu option for setting the shared device.

Accordingly, the transmitted sound image is reproduced or shared in the shared device, so that the user can view or share the selectively taken image with respect to the specific object (S14). In particular, when the captured image is played back in real time on a shared device, an indicator indicating that audio zooming is currently being performed on a specific target object is displayed on the screen of the shared device.

Whether or not the shared device is shared is performed after step (12), but it may be executed after step (S11). In addition, the steps (S11) to (S14) may be performed in a state of being connected or shared with the shared device and reproducing the image.

FIGS. 6A and 6B show an embodiment of a method for sharing audio-zoomed information of a mobile terminal shown in FIG. In particular, FIG. 6A shows a method of sharing the sound information when selecting a sound object directly from the reproduced image of the video player.

6A, when a predetermined image, for example, a kindergarten announcement image, is reproduced on the display unit 151 of the mobile terminal, an audio signal indicating that the corresponding image is a stereo image (or content) The zoom icon (50) (indicator) is displayed. The present invention is not limited to this, and the audio zoom icon 50 may be displayed even when a predetermined dictation mode is selected in the shooting mode. However, since the audio zooming command for selecting the audio zooming object (object) from the user has not yet been input, the audio zooming icon 50 remains inactive.

In this state, if the user selects a kindergarten student (eg, withdrawal) in order to intensively sound the voice of a specific object (eg, withdrawal), the control unit 180 activates the audio zoom icon 50 After entering the audio zooming mode, check whether the shared device is set.

If the sharer is set as a result of the check, the control unit 180 sounds the voice of the user and displays the pause range 51 around the faces of the five kindergarten students included in the preschool announcement image. At this time, the picked-up range 51 of the boiling water in which the picking is proceeding is displayed in a different color.

The intake range 51 is a square indicator formed by face recognition, and its size and shape can be set by a user through a menu. In particular, the size of the stagnation range 51 can be directly adjusted on the screen by a user's touch.

At least one or more of the intake ranges 51 may be selected and selected / canceled according to the user's selection. For example, if the indicator indicating the range of stooping is selected again, the stomach operation for that object is canceled.

The control unit 180 transmits the image of the voice of the caller to the shared device (e.g., TV) in real time and displays it on the screen of the shared device. At this time, in the displayed dictation image, an indicator 52 indicating who is currently audio-zooming (who is the object to be picked up) is displayed along with an audio zoom icon 50 indicating that the current audio zooming is being performed, (A).

In addition, when the audio zoom icon 50 is touched and deactivated during audio zooming, the control unit 180 stops the audio zooming and transmits / reproduces the stereo image having the original sound to the sharing device.

FIG. 6B shows a method of sharing the sound information at the time of selecting the sound object after selecting the audio zoom icon in the reproduced image of the video player.

The audio zooming mode may be performed by selecting an object to be picked up directly from the stereo image and entering the audio zooming icon 50 as shown in FIG. 6A, as shown in FIG. 6A.

When the audio zoom icon 50 is selected, the controller 180 activates the audio zoom icon 50 to enter an audio zooming mode, and then selects an object that can be selected every time frame of the image, for example, An indicator indicating the stagnation range 51 is displayed. When the audio zoom mode is selected at the time of video shooting, the audio zoom icon 50 is activated and displayed on the screen.

If, for example, the picked-up sound range 51 is selected from among the displayed plurality of picked-up ranges 51, the control unit 180 checks whether or not the shared equipment is set.

If the sharing device has been set as a result of the check, the control unit 180 receives the voice of the user in the stoop range 51 and transmits the stolen image to the predetermined sharing device for playback. At this time, the displayed dictation image includes an audio zoom icon 50 indicating that the current audio zooming is being performed, an indicator 52 indicating who is currently audio zooming Target indicator) is not displayed near the exit. The reason is that the display / non-display of the audio zoom icon 50 and the picking target indicator 52 displayed on the shared device can be set in the menu, and FIG.

FIG. 7 is another embodiment of the audio zoom-in sound information sharing method of the mobile terminal shown in FIG. In particular, FIG. 7 shows a method of sharing the sound information of a specific object with a rider during image reproduction of the gallery.

As shown in FIG. 7, at least one still image or moving image is stored in the gallery. The moving image includes a general image including a playback icon and a stereo image displaying an audio zoom icon (A).

When the user selects an audio zoom icon A of a predetermined stereo image (Girl Age image) in the gallery, the controller 180 enlarges the selected image and displays a sound range 51 (green) of each object Or displays the picked-up range 51 of each object while reproducing the selected image on the full screen. In another embodiment, after the partial image and the sound range 51 are displayed first, if a region other than the sound range 51 is touched, the corresponding image may be reproduced on the entire screen.

If a specific object to be taken on the partial enlarged image or the entire playback screen is selected, the controller 180 checks whether the shared device is set. If the sharing device is set as a result of checking, the voice of the selected object is picked up and the color of the object's sound range 51 is changed to a color different from the sound range 51 of another object, for example, red, Is being performed.

If the voice of the object is struck, the control unit 180 transmits the image including the stooped sound to the set shared device (e.g., TV) to be reproduced.

FIG. 8 is a flowchart showing an operation of selecting a shared device when selecting a sound object, and FIG. 9 is an example of a menu option for selecting a shared device.

If a predetermined object (object) to be taken in the stereo image is selected (when an audio zooming command is input), the control unit 180 checks whether a shared device is set (S20, S21). If a shared device is set as a result of the check, the sound of the selected target is acquired (S22). If the shared device is not set, the user selects a shared device and sounds a target sound (S23).

9, if the shared device is not set, the control unit 180 displays the audio zoom sharing menu 60 to allow the user to select the means for sharing the acquired sound information . The sharing means includes a message, a SNS, an e-mail, a kakao chat, and a Smart Share item as a kind of transmission means.

If the user selects smart sharing, the control unit 180 provides a smart sharing menu 61 to display a registered device item and a device search item from which the user can select a predetermined shared device. The user can select a registered device item to select a TV among the registered share devices (e.g., TV, electronic frame), or select another shared device through the device search item. The registered device may be added or deleted.

Figs. 10A and 10B are examples of the intake ranges corresponding to the respective intake modes when entering the audio zoom mode.

Referring to FIG. 10A, the range of the position-based intake range and the range of the stereo-based intake range are the intake ranges corresponding to the key position change mode and the stereo mode, respectively.

In the present invention, the user is able to set the user in the user mode at the time of capturing an image and at the time of image reproduction. The present invention is not limited to this, and the audio zoom icon can also be set to be long-touched at the time of image reproduction.

As shown in FIGS. 10A and 10B, the above-mentioned stooping range includes a key position changing mode, a stereo mode, a screen zoom interlocking mode, and a hearing aid mode.

The key position change mode is a mode for providing a range of a position-based key, and displays a range of a plurality of users on a face of a plurality of users through face recognition. The mode has a merit that users can pick up a desired sound range and only a voice of a user at a specific position can be taken, thereby focusing the sound of a user at various positions.

The stereo mode is a mode for providing a stereo-based sound range, and has the advantage of performing simultaneous two-channel (left channel and right channel) stunting for a subject having a high left / right position separation.

The screen-zoom linkage mode is a mode for providing a distance-based sound range. When the user zooms out or zooms in on the screen, the user changes the sound angle according to the zoom magnification, .

The hearing aid mode is a mode for providing an object-based sound range, and is a mode for selectively picking up a sound source occurring in a specific direction. In other words, the hearing aid mode is a mode for listening to the sound generated in a specific direction by applying audio zooming after being tapped through a microphone, and is a useful mode for listening to a performance or listening to lectures in a noisy environment.

The range of sound absorption according to each of the dictation modes may be set by a user at the time of image capturing and at the time of image reproduction. However, the present invention is not limited to this, and the control unit 180 may automatically determine the shape and distribution of the object displayed on the image.

The picked-up range is displayed when picking up an audio mode at the time of shooting (audio pick-up icon selection or audio zooming icon selection) when an audio zooming command is inputted at the time of image reproduction.

11 is an example of controlling the volume of the object to be picked up.

As shown in Fig. 11, the present invention can display the volume control icon 70 within the stooping range to adjust the volume of the stoop of the object of the stooping (e.g., withdrawal). The display setting of the volume control icon 70 is performed in a menu provided when the audio zoom icon 50 is touched by a long touch, and is displayed when a predetermined object to be picked up is selected.

The user can individually perform detailed breathing on the object to be picked up by operating the audio zoom icon 50 to encourage the volume of the object to be picked up (withdrawn).

On the other hand, in the audio zooming state, the object to be picked up can move to another position. For example, in a kindergarten image, a person who is a target of a breathing may move from a certain position to a position of another kindergarten after singing a rhythm.

In this way, when the position of the object to be picked up is moved in the audio zooming state, a sound is cut off or a sound of another kindergartener is struck. Audio handover is required to prevent the above phenomenon and keep the voice of the withdrawal.

The audio handover means that even if the selected object to be picked up is moved, the position of the object to be picked up is tracked and the picking up for the same picked up object is continued at the moved position. However, since the movement of the object to be taken is performed in a short period of time, a change in the voice of the user in a short period of time occurs.

Therefore, in the present invention, the movement of the object to be picked up is tracked, the range of the handwarming is handed over to the moved position, and when the movement is detected to return to the full picking mode, It provides a way to resume the stomach.

FIG. 12 is a flowchart illustrating an audio handover method according to movement of an object to be picked up in the present invention.

12, in the audio zooming mode, when a movement of the object to be picked up occurs while the upper layer image is being shared with another sharing device while being touched to a specific object to be picked up, (S30, S31). In this case, the movement of the object to be picked up means that it is not moved in place but its position is changed with another object or disappears from the image screen.

When the object to be taken is moved, the control unit 180 switches to a full taking mode in which voices of all the subjects are taken in a mode (individual mode) in which the voice of the object to be picked up is taken (S32) (S33). The tracking of the object to be picked up can use face recognition and can be performed in conjunction with the indoor position tracking system.

When the moved object is detected as a result of the tracing, the control unit 180 resumes the operation from the entire take-in mode to the individual take-in mode to resume the operation of picking up the voice of the object to be picked up (S34 and S35). After that, the user connects to the connected device and displays the sound image.

On the other hand, in the case where the object to be picked up moves out of the screen as a result of tracing movement of the object to be picked up (when the object to be picked up disappears), the controller 180 maintains the entire picked up mode and picks up the voices of all the objects.

13 is an embodiment of the audio handover method shown in FIG.

It is assumed that the voice of the object (a) is stuck in a stereo image including a plurality of objects (a to c) at present. When the movement of the object is detected in the audio zooming state, the controller 180 switches to a full acquisition mode in which the voices of all the objects a to c are taken in order to realize a soft reception.

When the object (a) is moved and its position is changed with the object (b), the controller (180) displays the range of the object a and returns the entire punch mode back to the individual punch mode, The voice of the object (a) is picked up again.

Accordingly, even if an object being sounded is moved during audio zooming, the present invention tracks the position of the object and performs a replay sound, so that the user can perform the sounding even if the user does not select a sound object.

14 shows an example of a method of controlling audio zooming in a shared device.

As shown in FIG. 14, the shared device can display an image transmitted from the mobile terminal in real time. In the above-described embodiment, the shared device is used only as a means for simply displaying a sound image transmitted from a mobile terminal during audio zooming.

However, the present invention is not limited to this, and the present invention can control an object displayed on a shared device by using a remote controller to control a licking operation performed through the mobile terminal. That is, when the user selects or enlarges a specific object on the currently displayed image using the remote controller, the mobile terminal requests the sound information for the object and receives and displays the sound image.

Therefore, when the user uses the above-described method, for example, when a user sits on a couch and watches a predetermined image through a TV, the user can conveniently perform selective listening using limon without operating the mobile terminal .

For the sake of convenience, the present invention has been described with reference to a sound image sharing and control method, for example, when a stereo image is reproduced. However, the present invention is equally applied to a stereo image.

As described above, according to the present invention, a sound of a specific object (audio object) zoomed in on a stereo image (a moving image or a playback image) is acquired and transmitted to another device to view the image on a larger screen, can do.

Further, according to the present invention, the movement and position of the object can be sensed when the object is moved, and the sound of the entire object can be sensed while moving to prevent the occurrence of the interruption of the sound and the other sounds.

In addition, the present invention can conveniently perform audio zooming by allowing a user to request a user to select a desired sound from a sound source of a specific object when transmitting the sound image to another device.

According to an embodiment of the present invention, the above-described method can be implemented as a computer-readable code on a medium on 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 the computer-readable medium include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and the like, and also implemented in the form of a carrier wave (for example, transmission over the Internet) . Further, the computer may include a control unit of the terminal.

The above-described method of sharing an audio zooming of a mobile terminal is not limited to the configuration and method of the above-described embodiments, but the embodiments may be modified so that all or some of the embodiments are selectively As shown in FIG.
