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. The proximity sensor 141 may detect 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, and a proximity touch movement state). have.

Meanwhile, the controller 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern detected 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. Further, the controller 180 may control the mobile terminal 100 to process different operations or data (or information) according to whether the touch on the same point on the touch screen is a proximity touch or a touch touch. .

The touch sensor applies a touch (or touch input) applied to the touch screen (or the display unit 151) using at least one of various touch methods such as a resistive film method, a capacitive method, an infrared method, an ultrasonic method, and a magnetic field method. Detect.

As an example, the touch sensor may be configured to convert a change in pressure applied to a specific portion of the touch screen or capacitance generated at the specific portion into an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the touch, a capacitance at the touch, and the like, when the touch object applying the touch on the touch screen is touched on the touch sensor. 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.

Meanwhile, the controller 180 may perform different control or perform the same control according to the type of touch object that touches the touch screen (or a touch key provided in addition to the touch screen). Whether to perform different control or the same control according to the type of touch object may be determined according to the operation state of the mobile terminal 100 or an application program being executed.

Meanwhile, the touch sensor and the proximity sensor described above may be independently or combined, and may be a short (or tap) touch, a long touch, a multi touch, a drag touch on a touch screen. ), Flick touch, pinch-in touch, pinch-out touch, swipe touch, hovering touch, etc. A touch can be sensed.

The ultrasonic sensor may recognize location information of a sensing object using ultrasonic waves. On the other hand, the controller 180 can calculate the position of the wave generation source through the information detected from the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the property that the light is much faster than the ultrasonic wave, that is, the time that the light reaches the optical sensor is much faster than the time when the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generation source may be calculated using a time difference from the time when the ultrasonic wave reaches the light as the reference signal.

On the other hand, the camera 121, which has been described as the configuration of the input unit 120, includes at least one of a camera sensor (eg, CCD, CMOS, etc.), a photo sensor (or an image sensor), and a laser sensor.

The camera 121 and the laser sensor may be combined with each other to detect a touch of a sensing object with respect to a 3D stereoscopic image. 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.

The display unit 151 displays (outputs) information processed by the mobile terminal 100. For example, the display unit 151 may display execution screen information of an application program driven in the mobile terminal 100 or user interface (UI) and graphical user interface (GUI) information according to the execution screen information. .

In addition, the display unit 151 may be configured as a stereoscopic display unit for displaying a stereoscopic image. The stereoscopic display unit may be a three-dimensional display method such as a stereoscopic method (glasses method), an auto stereoscopic method (glasses-free method), a projection method (holographic method).

Generally, a 3D stereoscopic image is composed of a left image (left eye image) and a right image (right eye image). A top-down method in which the left and right images are arranged up and down in one frame according to the way in which the left and right images are merged into three-dimensional stereoscopic images. L-to-R (left-to-right, side by side) method to be arranged as a checker board method to arrange the pieces of the left and right images in the form of tiles, a column unit of the left and right images Or an interlaced method of alternately arranging rows, and a time sequential (frame by frame) method of alternately displaying left and right images by time.

In addition, the 3D thumbnail image may generate a left image thumbnail and a right image thumbnail from the left image and the right image of the original image frame, respectively, and may be generated as one image as they are combined. In general, a thumbnail refers to a reduced image or a reduced still image. The left image thumbnail and the right image thumbnail generated as described above are displayed with a left and right distance difference on the screen by a depth corresponding to the parallax of the left image and the right image, thereby representing a three-dimensional space.

The left image and the right image necessary for implementing the 3D stereoscopic image may be displayed on the stereoscopic display by the stereoscopic processing unit.

Next, a communication system that can be implemented through the mobile terminal 100 according to the present invention will be described.

First, the communication system may use different air interfaces and / or physical layers. For example, a radio interface that can be used by a communication system includes frequency division multiple access (FDMA), time division multiple access (TDMA), and code division multiple access (CDMA). ), Universal Mobile Telecommunications Systems (UMTS) (especially Long Term Evolution (LTE), Long Term Evolution-Advanced (LTE-A)), Global System for Mobile Communications (GSM), etc. This may include.

Hereinafter, for convenience of description, the description will be limited to CDMA. However, it is apparent that the present invention can be applied to any communication system including an orthogonal frequency division multiplexing (OFDM) wireless communication system as well as a CDMA wireless communication system.

The CDMA wireless communication system includes at least one terminal 100, at least one base station (Base Station, BS (also referred to as Node B or Evolved Node B)), and at least one Base Station Controllers (BSCs). ), And may include a mobile switching center (MSC). The MSC is configured to connect with the Public Switched Telephone Network (PSTN) and BSCs. The BSCs may be connected to the BS through a backhaul line. The backhaul line may be provided according to at least one of E1 / T1, ATM, IP, PPP, Frame Relay, HDSL, ADSL, or xDSL. Thus, a plurality of BSCs can be included in a CDMA wireless communication system.

In addition, each sector may include two or more antennas of various types. Each BS may be configured to support a plurality of frequency assignments, and the plurality of frequency assignments may each have a specific spectrum (eg, 1.25 MHz, 5 MHz, etc.).

The intersection of sectors and frequency assignments may be called a CDMA channel. BSs may be called Base Station Transceiver Subsystems (BTSs). In this case, one BSC and at least one BS may be collectively referred to as a "base station". The base station may also indicate “cell site”. Or, each of the plurality of sectors for a particular BS may be called a plurality of cell sites.

The broadcast transmitter (BT) transmits a broadcast signal to the terminals 100 operating in the system. The broadcast receiving module 111 shown in FIG. 1 is provided in the terminal 100 to receive a broadcast signal transmitted by BT.

In addition, a satellite positioning system (Global Positioning System, GPS) for identifying the position of the mobile terminal 100 may be linked to the CDMA wireless communication system. The satellite helps to locate the mobile terminal 100. Useful location information may be obtained by up to two or more satellites. Here, the location of the mobile terminal 100 may be tracked using all the technologies capable of tracking the location as well as the GPS tracking technology. In addition, at least one of the GPS satellites may optionally or additionally be responsible for satellite DMB transmission.

The location information module 115 provided in the mobile terminal is used to detect, calculate, or identify the location of the mobile terminal. Examples of the location information module 115 may include a Global Position System (GPS) module and a Wireless Fidelity (WiFi) module. If necessary, the location information module 115 may perform any function of other modules of the wireless communication unit 110 to substitute or additionally obtain data regarding the location of the mobile terminal.

The GPS module 115 calculates distance information and accurate time information away from three or more satellites, and then triangulates the calculated information to accurately calculate three-dimensional current position information according to latitude, longitude, and altitude. can do. Currently, a method of calculating position and time information using three satellites and correcting the error of the calculated position and time information using another satellite is widely used. In addition, the GPS module 115 may calculate speed information by continuously calculating the current position in real time. However, it is difficult to accurately measure the position of the mobile terminal using the GPS module in the shadowed area of the satellite signal such as indoors. Accordingly, in order to compensate for GPS positioning, a WPS (WiFi Positioning System) may be utilized.

The Wi-Fi Positioning System (WPS) uses a WiFi module provided in the mobile terminal 100 and a wireless access point (AP) for transmitting or receiving a wireless signal with the WiFi module. As a technology for tracking the location of a, it refers to a WLAN (Wireless Local Area Network) based location positioning technology using WiFi.

The Wi-Fi location tracking system may include a Wi-Fi location server, a mobile terminal 100, a wireless AP connected to the mobile terminal 100, and a database in which any wireless AP information is stored.

The mobile terminal 100 connected to the wireless AP may transmit a location information request message to the Wi-Fi location server.

The Wi-Fi positioning server extracts the information of the wireless AP connected to the mobile terminal 100 based on the location information request message (or signal) of the mobile terminal 100. Information of the wireless AP connected to the mobile terminal 100 may be transmitted to the Wi-Fi positioning server through the mobile terminal 100, or may be transmitted from the wireless AP to the Wi-Fi positioning server.

Based on the location information request message of the mobile terminal 100, the extracted information of the wireless AP is MAC Address, Service Set IDentification (SSID), Received Signal Strength Indicator (RSSI), Reference Signal Received Power (RSRP), RSRQ ( It may be at least one of Reference Signal Received Quality, Channel Information, Privacy, Network Type, Signal Strength, and Noise Strength.

As described above, the Wi-Fi location server receives the information of the wireless AP connected to the mobile terminal 100, and extracts the wireless AP information corresponding to the wireless AP to which the mobile terminal is connected from a pre-established database. At this time, the information of any wireless AP stored in the database is MAC address, SSID, channel information, Privacy, Network Type, latitude and longitude coordinates of the wireless AP, building name, floor number, indoor detailed location information (GPS coordinates) Available), the AP owner's address, telephone number, and the like. In this case, in order to remove the wireless AP provided by the mobile AP or the illegal MAC address in the positioning process in the positioning process, the Wi-Fi positioning server may extract only a predetermined number of wireless AP information in the order of high RSSI.

Thereafter, the Wi-Fi location server may extract (or analyze) location information of the mobile terminal 100 using at least one piece of wireless AP information extracted from a database. The location information of the mobile terminal 100 is extracted (or analyzed) by comparing the included information with the received wireless AP information.

As a method for extracting (or analyzing) the location information of the mobile terminal 100, a cell-ID method, a finger print method, a triangulation method, a landmark method, or the like may be utilized.

The Cell-ID method is a method of determining a location of a mobile AP having the strongest signal strength among neighboring wireless AP information collected by the mobile terminal. The simple implementation, no additional cost, and quick location information can be obtained. However, the low installation density of the wireless AP reduces the positioning accuracy.

The fingerprint method is a method of selecting a reference location in a service area to collect signal strength information and estimating a location based on signal strength information transmitted from a mobile terminal based on the collected information. In order to use the fingerprint method, it is necessary to database propagation characteristics in advance.

The triangulation method calculates the position of the mobile terminal based on the coordinates of at least three wireless APs and the distance between the mobile terminals. In order to measure the distance between the mobile terminal and the wireless AP, the signal strength is converted into distance information, a time of arrival of a radio signal (ToA), a time difference of transmission of a signal (Time Difference of Arrival, TDoA) , Angle of signal transmission (Angle of Arrival, AoA) may be used.

The landmark method is a method of measuring the location of a mobile terminal using a landmark transmitter that knows the location.

In addition to the methods listed, various algorithms may be utilized as a method for extracting (or analyzing) location information of a mobile terminal.

The extracted location information of the mobile terminal 100 is transmitted to the mobile terminal 100 through the Wi-Fi positioning server, the mobile terminal 100 can obtain the location information.

The mobile terminal 100 may obtain location information by being connected to at least one wireless AP. In this case, the number of wireless APs required to obtain location information of the mobile terminal 100 may be variously changed according to a wireless communication environment in which the mobile terminal 100 is located.

As described above with reference to FIG. 1, the mobile terminal according to the present invention includes Bluetooth ™, Radio Frequency Identification (RFID), Infrared Data Association (IrDA), Ultra Wideband (UWB), ZigBee, and NFC (Near). Short-range communication technologies such as Field Communication, Wireless USB (Wireless Universal Serial Bus), and the like may be applied.

Among these, the NFC module provided in the mobile terminal supports contactless short-range wireless communication between terminals at a distance of about 10 cm. The NFC module may operate in any one of a card mode, a reader mode, and a P2P mode. In order for the NFC module to operate in a card mode, the mobile terminal 100 may further include a security module for storing card information. Here, the security module may be a physical medium such as a universal integrated circuit card (UICC) (for example, a subscriber identification module (SIM) or a universal SIM (USIM)), a secure micro SD, and a sticker, or a logical medium embedded in a mobile terminal ( For example, it may be an embedded SE (Secure Element). Data exchange based on a single wire protocol (SWP) may be performed between the NFC module and the security module.

When the NFC module is operated in the card mode, the mobile terminal can transmit the stored card information to the outside like a conventional IC card. Specifically, when the mobile terminal storing the card information of the payment card such as a credit card or bus card is close to the toll payment machine, the mobile short-range payment can be processed, and the mobile terminal storing the card information of the access card is approved for access. Close to the flag, the approval process can be started. Cards such as credit cards, transportation cards, and access cards are mounted in a security module in the form of an applet, and the security module may store card information about the mounted card. Here, the card information of the payment card may be at least one of a card number, balance, and usage history, and the card information of the access card may include at least one of a user's name, number (eg, student's student number or company number), and access history. It can be one.

When the NFC module is operated in the reader mode, the mobile terminal can read data from an external tag. In this case, the data received by the mobile terminal from the tag may be coded in a data exchange format (NFC Data Exchange Format) determined by the NFC forum. In addition, the NFC Forum defines four record types. Specifically, the NFC forum defines four record type definitions (RTDs) such as smart poster, text, uniform resource identifier (URI), and general control. If the data received from the tag is a smart poster type, the controller may execute a browser (eg, an Internet browser). If the data received from the tag is a text type, the controller may execute a text viewer. When the data received from the tag is a URI type, the controller executes a browser or makes a phone call, and when the data received from the tag is a general control type, the controller can execute an appropriate operation according to the control content.

When the NFC module is operated in a peer-to-peer mode, the mobile terminal may perform P2P communication with another mobile terminal. In this case, LLCP (Logical Link Control Protocol) may be applied to P2P communication. A connection may be created between the mobile terminal and another mobile terminal for P2P communication. In this case, the generated connection may be classified into a connectionless mode in which one packet is exchanged and terminated, and a connection-oriented mode in which packets are continuously exchanged. Through P2P communication, data such as electronic business cards, contact information, digital photos, URLs, and setup parameters for Bluetooth and Wi-Fi connections can be exchanged. However, since the available distance of NFC communication is short, the P2P mode may be effectively used for exchanging small data.

Hereinafter, embodiments related to a control method that can be implemented in the mobile terminal configured as described above will be described with reference to the accompanying drawings. It is apparent to those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit and essential features of the present invention.

That is, the photographing apparatus 200 may acquire the omnidirectional image 300 having a spherical shape corresponding to the omnidirectional background based on the photographing apparatus 200. The obtained omnidirectional image 300 may be transmitted to the mobile terminal 100.

The display unit 151 of the mobile terminal 100 may display some images of the omnidirectional image 300 corresponding to a specific area. For example, the display unit 151 of the mobile terminal 100 displays the first partial image 310 corresponding to the first area of the omnidirectional image 300 or the second partial image corresponding to the second area ( 330 may be displayed.

Some images displayed by the display unit 151 may vary depending on the user's setting or may be set as a default.

In the case of FIG. 4A (b), it is confirmed that a circular substitute display 402 is displayed at the position of the user 401 by post-processing the captured omnidirectional image.

Referring to FIG. 4B, in the case of the image 403 in which the omnidirectional image is displayed in a circular shape, it is confirmed that the alternative display 404 is displayed on a part of the photographer 401.

Referring to FIG. 4C, in the case of the image 405 displaying the entire image of the omnidirectional image, it can be seen that the replacement display 406 is displayed under the photographer 401.

4A to 4C, when photographing the omnidirectional image using the omnidirectional photographing apparatus 200, a part of the photographer 401 is continuously displayed on the image, and the position of the photographer 401 is determined by the omnidirectional photographing apparatus ( When the camera 200 photographs the omnidirectional image using a plurality of cameras, the photographer 401 is positioned at a position where the images captured by the respective cameras are connected to each other, thereby causing a problem of the image of the photographer 401 being broken.

Therefore, it may be said that it is preferable to delete the photographer 401 like the image 410 of FIG. 4D.

Can also be found in past omnidirectional images.

The controller 180 of the mobile terminal 100 synthesizes the moving area image into the omnidirectional image (S411).

According to an embodiment, the controller 180 may synthesize the omnidirectional image received from the omnidirectional photographing apparatus 200 and the moving area image to delete all and some images of the image of the photographer 401 of the omnidirectional image.

Unlike the image 602 of the second time, the synthesized image 603 may confirm that the photographer 401 disappears. That is, according to the present invention, it is possible to obtain an advantage of eliminating a problem in which unwanted subjects are photographed by deleting the photographer from the omnidirectional image.

In addition, according to an exemplary embodiment of the present invention, when the photographer moves to the third area 623, the controller 180 of the mobile terminal 100 may display the second time in the third area (not shown) of the third time. The synthesized image may be generated by synthesizing the image of the third region. That is, the controller 180 of the mobile terminal 100 may repeatedly perform the same method as described above to remove the image of the photographer 401 from the omnidirectional image.

In another embodiment of the present invention, the photographer 401 may be deleted at the first time by synthesizing the first area (611) of the second time with the first area 611 of the first time. Since the detailed method is similar to the above-mentioned method, the detailed description is omitted.

The omnidirectional photographing apparatus 200 may photograph an omnidirectional image, which is an image in all directions, and may include a lower end of the omnidirectional photographing apparatus 200.

Referring to FIG. 7A (a), the omnidirectional photographing apparatus 200 may photograph regions of the first region 701, the second region 702, and the third region 703 that form the same interval.

Referring to FIG. 7A (b), when the omnidirectional photographing apparatus 200 moves 1 m to the second region 712, the omnidirectional photographing apparatus 200 may have a second region 712 and a third region 713 having the same interval. ) And an area of the fourth area 714 may be photographed.

As described above, the omnidirectional photographing apparatus 200 may obtain different images at different times even in the same area. Therefore, the feature can be used to remove the photographer.

7B is a diagram for describing a method of obtaining an area occupied by a photographer.

Referring to (b) of FIG. 7B, the portion 731 covered by the photographer's body or the like may be confirmed in the captured omnidirectional image 740.

The controller 180 of the mobile terminal 100 is obscured using the heights 770 and h of the omnidirectional photographing apparatus 200 and the angle 750 of the part 731 covered by the photographer's body in the omnidirectional image 740. The radius of the portion 760, r can be obtained. However, when the angles 750 and θ of the part 731 covered by the photographer's body and the like change depending on the position, the largest value can be used.

[Equation 1]

r = h * tanθ

In more detail, the controller 180 of the mobile terminal 100 can obtain the radii 760 and r of the part covered by Equation 1.

Therefore, the controller 180 of the mobile terminal 100 may set the area 732 covered by the lower end of the omnidirectional photographing apparatus 200.

Referring to FIG. 7C, the controller 180 of the mobile terminal 100 may set the first area 791 that is covered by the lower end of the omnidirectional photographing apparatus 200 by the above-described method.

In addition, when the photographer moves in the direction of the arrow 793, the second region 792 having the same shape and size as the first region 791 may be set.

In the present invention, the region to be synthesized must have the same shape and size to effectively synthesize.

Referring to FIG. 6C, the controller 180 of the mobile terminal 100 synthesizes an image of the second area 612 of the first time in the second area 622 of the second time to generate a synthesized image 603. can do.

6A-6C and 8, the second region 622 of the second time and the second region 612 of the first time have the same size because they are substantially the same area, but the first time and Since the position of the omnidirectional photographing apparatus 200 is different at the second time, the sizes of the second region 622 of the second time and the second region 612 of the first time may be different. In addition, referring to FIG. 8 (a), it can be seen that the first region 802 and the second region 801 have substantially the same shape and area, and have different sizes in the omnidirectional image.

Accordingly, the controller of the mobile terminal may correct the size of the captured image 811 as the image 812 for synthesis.

According to an embodiment of the present disclosure, the controller 180 of the mobile terminal 100 may enlarge the size of the second area 612 of the first time to be equal to the size of the second area 622 of the second time. . That is, as illustrated in FIG. 8B, the size of the image 811 captured for synthesis may be corrected to the image 812 for synthesis.

Therefore, a natural image can be obtained after synthesis as shown in FIG.

9A to 9D, when the photographer 401 vertically positions and moves the omnidirectional photographing apparatus 200 for the head, the photographer 401 may be deleted.

According to an embodiment of the present disclosure, the controller 180 of the mobile terminal 100 may include the omnidirectional photographing apparatus 200 in order for the controller 180 of the mobile terminal 100 to delete the photographer 401 from the display unit 151. Information 902 about the distance to be moved may be displayed.

In an exemplary embodiment of the present invention, the controller 180 of the mobile terminal 100 is the omnidirectional photographing apparatus 200 so that the controller 180 of the mobile terminal 100 deletes the photographer 401 on the display unit 151. May be indicated by an arrow 903. The arrow 903 may change the size of the color painted therein according to the moving distance. The controller 180 of the mobile terminal 100 may display an empty arrow 903 on the display unit 151 when the distance to which the omnidirectional photographing apparatus 200 needs to move is insufficient. In addition, the controller 180 of the mobile terminal 100 may display a solid arrow 904 on the display unit 151 when the omnidirectional photographing apparatus 200 has a sufficient distance to move. In addition, when the movement is completed, the synthesized image 905 may be displayed on the display unit 151.

10A and 10B, since the omnidirectional photographing apparatus 200 may photograph an image in all directions, the controller 180 of the mobile terminal 100 analyzes the omnidirectional image photographed by the omnidirectional photographing apparatus 200. The surrounding moving objects 1001 to 1003 can be sensed.

Accordingly, the controller 180 of the mobile terminal 100 may find an optimal direction 1004 for removing the photographer 401. The optimal direction 1004 may be a direction in which the moving objects 1001 to 1003 and the moving copper wires do not overlap.

The controller 180 of the mobile terminal 100 may display information 1011 to 1013 corresponding to the moving objects 1001 to 1003 around the display unit 151. In addition, the controller 180 of the mobile terminal 100 may display an optimal direction 1020 for removing the photographer 401 from the surrounding moving objects 1001 to 1003. In addition, the direction 1020 may be displayed with a distance for movement.

11A and 11B, when there is a moving object in the area 1101 for capturing an image for compositing, the controller 180 of the mobile terminal 100 is configured to capture an image for compositing a moving object. In the case of moving away from the region 1101, the image 1112 of the region may be stored.

That is, referring to FIGS. 6A to 6C, when there is a moving object in the second area, the controller 180 of the mobile terminal 100 determines that the second time is moved when the moving object of the second area is out of the second area. An image of the second region of the first time may be synthesized in the two regions.

Referring to FIG. 12A, the photographer 401 may capture the omnidirectional image in a state where the omnidirectional image photographing unit 200 is located in front of the user rather than on the head.

In this case, as illustrated in FIG. 12B, the photographer 401 is not positioned at the vertical portion of the omnidirectional photographing device in the omnidirectional image. In addition, as the angle at which the image is taken increases, the space occupied by the photographer 401 in the omnidirectional image becomes larger.

Preferably, the omnidirectional photographing apparatus may be more easily deleted at the position perpendicular to the head of the photographer 401.

In an embodiment of the present disclosure, when the photographer 401 photographs the omnidirectional image while the omnidirectional photographing apparatus 200 is located in front of the user rather than on the head, the photographer 401 rotates the forward direction image photographing unit 200. 401 may be deleted.

For example, when photographing using the omnidirectional photographing apparatus 200 as illustrated in FIG. 12C, the photographer 401 may be located in a predetermined region 1201 of the omnidirectional photographing apparatus 200. In this case, the photographer is disposed at a position corresponding to the predetermined area 1201 in the omnidirectional image. In this state, when the photographer moves to the front, since the photographer 401 is positioned at the same angle of the omnidirectional photographing apparatus 200, the photographer 401 may not be removed using the above-described method.

Therefore, in this case, the controller 180 of the mobile terminal 100 may display a guide for the photographer 401 to rotate on the display unit 151 of the mobile terminal 100.

Referring to FIG. 12D, when the photographer 410 rotates 1202, the location of the region 1201 covered by the photographer 401 when the omnidirectional image is captured by the omnidirectional photographing apparatus 200 is changed. Therefore, the controller 180 of the mobile terminal 100 can obtain an image of an area covered by the photographer 401 before rotation. The controller 180 of the mobile terminal 100 obtains a first image including the photographer of the omnidirectional photographing apparatus positioned in the first region from the omnidirectional image, and the omnidirectional photographing apparatus is moved or rotated to omnidirectionally at the position of the first region. The second image without the photographer of the photographing apparatus may be acquired, and the second image may be synthesized with the first image to delete the photographer of the omnidirectional photographing apparatus from the omnidirectional image.

Accordingly, the controller 180 of the mobile terminal 100 may obtain an image 1210 from which the photographer 401 is removed as shown in FIG. 12E.

According to an embodiment of the present invention, the location information module may be used to more accurately measure the position of the omnidirectional photographing apparatus 200 to obtain a composite image from which the more accurate photographer 401 is removed.

As shown in FIG. 13A, information about the location of the second area 1301 at the first time may be measured using the location information module. GPS positioning method calculates distance information and accurate time information from three or more satellites and then applies triangulation to the calculated information to accurately calculate three-dimensional current position information according to latitude, longitude, and altitude. can do. Currently, location and time information may be calculated using three satellites, and the error of the calculated location and time information may be corrected using another satellite.

In addition, as illustrated in FIGS. 13B and 13C, the location information module may measure whether the omnidirectional photographing apparatus 200 is positioned in the second area 1301 at the second time. Therefore, when the omnidirectional photographing apparatus 200 is located in the second area 1301, the controller 180 of the mobile terminal 100 synthesizes an image of the second area of the first time by combining the image of the second area of the first time. The generated image 1302 may be generated.

Referring to FIG. 14A, the photographer 401 may capture the omnidirectional image in a state where the omnidirectional image photographing unit 200 is located in front of the user rather than on the head.

When the gesture for removing the photographer 401 is input when the omnidirectional photographing apparatus is tilted as shown in FIG. 14B, the controller 180 of the mobile terminal 100 may not remove the photographer 401 smoothly.

Therefore, in an embodiment of the present invention, the controller 180 of the mobile terminal 100 includes guides 1410 to 1430 for positioning the omnidirectional photographing apparatus 200 perpendicular to the head of the photographer 401. ) May be displayed on the display unit 151.

In another embodiment of the present disclosure, when the omnidirectional photographing apparatus 200 is not positioned perpendicular to the head of the photographer 401, the controller 180 of the mobile terminal 100 stops photographing the omnidirectional image, and the omnidirectional photographing apparatus ( Guidance texts 1410 to 1430 for positioning 200 to be perpendicular to the head of the photographer 401 may be displayed on the display unit 151 of the mobile terminal 100.

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 those implemented 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.
