Description

MOBILE TERMINAL AND METHOD OF CONTROLLING THE SAME

The present disclosure relates to a mobile terminal and a method of controlling the same, which can perform control related to image photographing.

A mobile terminal includes all types of devices provided with a battery and a display unit and carried by a user. The mobile terminal is configured to output information to the display unit using power supplied from the battery. The mobile terminal includes a device for recording and playing moving images, a device for displaying a graphic user interface (GUI), etc., which includes a notebook, a mobile phone, glasses, a watch, a game console, etc.

Mobile terminals have become increasingly more functional. Examples of such functions include data and voice communications, capturing images and video via a camera, recording audio, playing music files via a speaker system, and displaying images and video on a display. Some mobile terminals include additional functionality which supports game playing, while other terminals are configured as multimedia players. More recently, mobile terminals have been configured to receive broadcast and multicast signals which permit viewing of content such as videos and television programs.

Efforts are ongoing to support and increase the functionality of mobile terminals. Such efforts include software and hardware improvements, as well as changes and improvements in the structural components.

Recently, various techniques for controlling driving of an external device connected by wireless to a mobile terminal have been developed. Further, a technique for continuously photographing images through the external device at various angles and places without any spatial limitation has been developed.

Therefore, an object of the present disclosure is to provide a mobile terminal capable of controlling a moving means and/or a camera to continuously photograph images at various angles and places.

To achieve these and other advantages and in accordance with the purpose of the present disclosure, as embodied and broadly described herein, there is provided a mobile terminal communicating with a moving means, including: a camera; a touch screen configured to output an image through the camera; and a controller configured to generate a traveling path of the moving means, based on a touch applied on the touch screen in a state in which the image is output, wherein the traveling path includes a path along which the moving means moves to an area corresponding to a portion at which the touch is applied in a moving target area corresponding to the image.

When the touch is a drag touch, the controller may control the moving means to move along a path including an area corresponding to a trace of the drag touch.

The controller may control the camera to photograph surroundings while the moving means is moving in the area corresponding to the trace of the drag touch.

The controller may control the moving means such that a moving speed of the moving means is changed depending on an input speed of the drag touch.

The controller may output a graphic object corresponding to the trace of the drag touch on the touch screen. The controller may display the graphic object in different colors for every section, based on the input speed.

The controller may output a graphic object corresponding to the trace of the drag touch on the touch screen. If a predetermined touch different from the drag touch is input on the graphic object after the drag touch is released, the controller may perform a predetermined function corresponding to the predetermined touch.

When the predetermined touch is a long touch that is a touch continuously sensed at the same position for a predetermined time, the controller may output an image object related to zoom-in/out adjustment of the camera near a position at which the long touch is sensed such that the degree of zoom-in/out adjustment is changed while the moving means is moving in an area corresponding to the position at which the long touch is sensed.

When another drag touch of which input is started is sensed on the graphic object, the controller may control the touch screen such that the graphic object is moved based on a position at which the input of the another drag touch is completed. The may control the moving means to move along a path including an area corresponding to the moved graphic object in the moving target area.

When a tap touch is sensed at a position corresponding to the graphic object, the controller may output an image object for changing a size or shape of the graphic object at an edge of the graphic object. The controller may control the touch screen such that the size or shape of the graphic object is changed based on a touch input to the graphic object. The controller may control the moving means to move along a path including an area corresponding to the changed graphic object in the moving target area.

When the drag touch is sensed while a touch different from the drag touch is being sensed, the controller may control the camera to photograph a subject corresponding to an image object of an image to which the touch is applied.

The controller may control the camera to perform auto-focusing on the subject while the moving means is moving in the area corresponding to the trace of the drag touch.

The controller may output, on the touch screen, a moving image photographed by the camera while the moving means is moving along the traveling path. If a touch is applied to the moving image while the moving image is being reproduced, the controller may output a graphic object corresponding to the drag touch and an indicator at a position corresponding to a point at which the moving image to which the touch is applied is photographed on the graphic object.

The controller may divide the touch screen into a first area and a second area. The may output the moving image in one of the first area and the second area, and outputs the graphic object and the indicator in the other of the first area and the second area.

The moving means may be formed to allow a main body of the mobile terminal to be attachable/detachable thereto/therefrom. If a user request for moving the moving means is input after the main body of the mobile terminal is mounted to the moving means, the controller may control the moving means to start moving along the traveling path.

The camera may include a first camera formed in the main body of the mobile terminal and a second camera formed in the moving means. The photographing may be performed by at least one of the first camera and the second camera.

According to the present disclosure, the moving means can move along a traveling path including an area corresponding to a portion at which a touch is applied in a moving target area corresponding to a guide image. Accordingly, a plan for traveling of the moving means can be more intuitively and easily made by a user.

Also, while the moving means is moving, a subject can be photographed through the camera of the mobile terminal, mounted to the moving means, and/or the camera separately provided to the moving means. Accordingly, continuous image photographing can be stably performed at more various angles and/or places.

Also, since image photographing is performed by using the moving means, the image photographing can be easily performed even though the user is spaced apart from the subject at a considerable distance.

The mobile terminal 100 may be configured to utilize information obtained from sensing unit 140, and in particular, information obtained from one or more sensors of the sensing unit 140, and combinations thereof.

The output unit 150 is typically configured to output various types of information, such as audio, video, tactile output, and the like. The output unit 150 is shown having a display unit 151, an audio output module 152, a haptic module 153, and an optical output module 154.

The display unit 151 may have an inter-layered structure or an integrated structure with a touch sensor in order to facilitate a touch screen. The touch screen may provide an output interface between the mobile terminal 100 and a user, as well as function as the user input unit 123 which provides an input interface between the mobile terminal 100 and the user.

The interface unit 160 serves as an interface with various types of external devices that can be coupled to the mobile terminal 100. The interface unit 160, for example, may include any of wired or wireless ports, external power supply ports, wired or wireless data ports, memory card ports, ports for connecting a device having an identification module, audio input/output (I/O) ports, video I/O ports, earphone ports, and the like. In some cases, the mobile terminal 100 may perform assorted control functions associated with a connected external device, in response to the external device being connected to the interface unit 160.

The memory 170 is typically implemented to store data to support various functions or features of the mobile terminal 100. For instance, the memory 170 may be configured to store application programs executed in the mobile terminal 100, data or instructions for operations of the mobile terminal 100, and the like. Some of these application programs may be downloaded from an external server via wireless communication. Other application programs may be installed within the mobile terminal 100 at time of manufacturing or shipping, which is typically the case for basic functions of the mobile terminal 100 (for example, receiving a call, placing a call, receiving a message, sending a message, and the like). It is common for application programs to be stored in the memory 170, installed in the mobile terminal 100, and executed by the controller 180 to perform an operation (or function) for the mobile terminal 100.

The controller 180 typically functions to control overall operation of the mobile terminal 100, in addition to the operations associated with the application programs. The controller 180 may provide or process information or functions appropriate for a user by processing signals, data, information and the like, which are input or output by the various components depicted in Fig. 1A, or activating application programs stored in the memory 170. As one example, the controller 180 controls some or all of the components illustrated in FIGS. 1A-1C according to the execution of an application program that have been stored in the memory 170.

The power supply unit 190 can be configured to receive external power or provide internal power in order to supply appropriate power required for operating elements and components included in the mobile terminal 100. The power supply unit 190 may include a battery, and the battery may be configured to be embedded in the terminal body, or configured to be detachable from the terminal body.

At least some of the above components may operate in a cooperating manner, so as to implement an operation or a control method for a glass type terminal according to various embodiments to be explained later. The operation or the control method for the glass type terminal may be implemented on the glass type terminal by driving at least one application program stored in the memory 170.

Referring still to FIG. 1A, various components depicted in this figure will now be described in more detail. Regarding the wireless communication unit 110, the broadcast receiving module 111 is typically configured to receive a broadcast signal and/or broadcast associated information from an external broadcast managing entity via a broadcast channel. The broadcast channel may include a satellite channel, a terrestrial channel, or both. In some embodiments, two or more broadcast receiving modules 111 may be utilized to facilitate simultaneously receiving of two or more broadcast channels, or to support switching among broadcast channels.

The mobile communication module 112 can transmit and/or receive wireless signals to and from one or more network entities. Typical examples of a network entity include a base station, an external mobile terminal, a server, and the like. Such network entities form part of a mobile communication network, which is constructed according to technical standards or communication methods for mobile communications (for example, Global System for Mobile Communication (GSM), Code Division Multi Access (CDMA), CDMA2000(Code Division Multi Access 2000), EV-DO(Enhanced Voice-Data Optimized or Enhanced Voice-Data Only), Wideband CDMA (WCDMA), High Speed Downlink Packet access (HSDPA), HSUPA(High Speed Uplink Packet Access), Long Term Evolution (LTE) , LTE-A(Long Term Evolution-Advanced), and the like). Examples of wireless signals transmitted and/or received via the mobile communication module 112 include audio call signals, video (telephony) call signals, or various formats of data to support communication of text and multimedia messages.

The wireless Internet module 113 is configured to facilitate wireless Internet access. This module may be internally or externally coupled to the mobile terminal 100. The wireless Internet module 113 may transmit and/or receive wireless signals via communication networks according to wireless Internet technologies.

Examples of such wireless Internet access include Wireless LAN (WLAN), Wireless Fidelity (Wi-Fi), Wi-Fi Direct, Digital Living Network Alliance (DLNA), Wireless Broadband (WiBro), Worldwide Interoperability for Microwave Access (WiMAX), High Speed Downlink Packet Access (HSDPA), HSUPA(High Speed Uplink Packet Access), Long Term Evolution (LTE), LTE-A(Long Term Evolution-Advanced), and the like. The wireless Internet module 113 may transmit/receive data according to one or more of such wireless Internet technologies, and other Internet technologies as well.

In some embodiments, when the wireless Internet access is implemented according to, for example, WiBro, HSDPA,HSUPA, GSM, CDMA, WCDMA, LTE, LTE-A and the like, as part of a mobile communication network, the wireless Internet module 113 performs such wireless Internet access. As such, the Internet module 113 may cooperate with, or function as, the mobile communication module 112.

The short-range communication module 114 is configured to facilitate short-range communications. Suitable technologies for implementing such short-range communications include BLUETOOTHTM, Radio Frequency IDentification (RFID), Infrared Data Association (IrDA), Ultra-WideBand (UWB), ZigBee, Near Field Communication (NFC), Wireless-Fidelity (Wi-Fi), Wi-Fi Direct, Wireless USB(Wireless Universal Serial Bus), and the like. The short-range communication module 114 in general supports wireless communications between the mobile terminal 100 and a wireless communication system, communications between the mobile terminal 100 and another mobile terminal 100, or communications between the mobile terminal and a network where another mobile terminal 100 (or an external server) is located, via wireless area networks. One example of the wireless area networks is a wireless personal area networks.

In some embodiments, another mobile terminal (which may be configured similarly to mobile terminal 100) may be a wearable device, for example, a smart watch, a smart glass or a head mounted display (HMD), which is able to exchange data with the mobile terminal 100 (or otherwise cooperate with the mobile terminal 100). The short-range communication module 114 may sense or recognize the wearable device, and permit communication between the wearable device and the mobile terminal 100. In addition, when the sensed wearable device is a device which is authenticated to communicate with the mobile terminal 100, the controller 180, for example, may cause transmission of data processed in the mobile terminal 100 to the wearable device via the short-range communication module 114. Hence, a user of the wearable device may use the data processed in the mobile terminal 100 on the wearable device. For example, when a call is received in the mobile terminal 100, the user may answer the call using the wearable device. Also, when a message is received in the mobile terminal 100, the user can check the received message using the wearable device.

The location information module 115 is generally configured to detect, calculate, derive or otherwise identify a position of the mobile terminal. As an example, the location information module 115 includes a Global Position System (GPS) module, a Wi-Fi module, or both. If desired, the location information module 115 may alternatively or additionally function with any of the other modules of the wireless communication unit 110 to obtain data related to the position of the mobile terminal.

As one example, when the mobile terminal uses a GPS module, a position of the mobile terminal may be acquired using a signal sent from a GPS satellite. As another example, when the mobile terminal uses the Wi-Fi module, a position of the mobile terminal can be acquired based on information related to a wireless access point (AP) which transmits or receives a wireless signal to or from the Wi-Fi module.

The input unit 120 may be configured to permit various types of input to the mobile terminal 120. Examples of such input include audio, image, video, data, and user input. Image and video input is often obtained using one or more cameras 121. Such cameras 121 may process image frames of still pictures or video obtained by image sensors in a video or image capture mode. The processed image frames can be displayed on the display unit 151 or stored in memory 170. In some cases, the cameras 121 may be arranged in a matrix configuration to permit a plurality of images having various angles or focal points to be input to the mobile terminal 100. As another example, the cameras 121 may be located in a stereoscopic arrangement to acquire left and right images for implementing a stereoscopic image.

The microphone 122 is generally implemented to permit audio input to the mobile terminal 100. The audio input can be processed in various manners according to a function being executed in the mobile terminal 100. If desired, the microphone 122 may include assorted noise removing algorithms to remove unwanted noise generated in the course of receiving the external audio.

The user input unit 123 is a component that permits input by a user. Such user input may enable the controller 180 to control operation of the mobile terminal 100. The user input unit 123 may include one or more of a mechanical input element (for example, a key, a button located on a front and/or rear surface or a side surface of the mobile terminal 100, a dome switch, a jog wheel, a jog switch, and the like), or a touch-sensitive input, among others. As one example, the touch-sensitive input may be a virtual key or a soft key, which is displayed on a touch screen through software processing, or a touch key which is located on the mobile terminal at a location that is other than the touch screen. On the other hand, the virtual key or the visual key may be displayed on the touch screen in various shapes, for example, graphic, text, icon, video, or a combination thereof.

The sensing unit 140 is generally configured to sense one or more of internal information of the mobile terminal, surrounding environment information of the mobile terminal, user information, or the like. The controller 180 generally cooperates with the sending unit 140 to control operation of the mobile terminal 100 or execute data processing, a function or an operation associated with an application program installed in the mobile terminal based on the sensing provided by the sensing unit 140. The sensing unit 140 may be implemented using any of a variety of sensors, some of which will now be described in more detail.

The proximity sensor 141 may include a sensor to sense presence or absence of an object approaching a surface, or an object located near a surface, by using an electromagnetic field, infrared rays, or the like without a mechanical contact. The proximity sensor 141 may be arranged at an inner region of the mobile terminal covered by the touch screen, or near the touch screen.

The proximity sensor 141, for example, may include any of a transmissive type photoelectric sensor, a direct reflective type photoelectric sensor, a mirror reflective type photoelectric sensor, a high-frequency oscillation proximity sensor, a capacitance type proximity sensor, a magnetic type proximity sensor, an infrared rays proximity sensor, and the like. When the touch screen is implemented as a capacitance type, the proximity sensor 141 can sense proximity of a pointer relative to the touch screen by changes of an electromagnetic field, which is responsive to an approach of an object with conductivity. In this case, the touch screen (touch sensor) may also be categorized as a proximity sensor.

The term “proximity touch” will often be referred to herein to denote the scenario in which a pointer is positioned to be proximate to the touch screen without contacting the touch screen. The term “contact touch” will often be referred to herein to denote the scenario in which a pointer makes physical contact with the touch screen. For the position corresponding to the proximity touch of the pointer relative to the touch screen, such position will correspond to a position where the pointer is perpendicular to the touch screen. The proximity sensor 141 may sense proximity touch, and proximity touch patterns (for example, distance, direction, speed, time, position, moving status, and the like).

In general, controller 180 processes data corresponding to proximity touches and proximity touch patterns sensed by the proximity sensor 141, and cause output of visual information on the touch screen. In addition, the controller 180 can control the mobile terminal 100 to execute different operations or process different data according to whether a touch with respect to a point on the touch screen is either a proximity touch or a contact touch.

A touch sensor can sense a touch applied to the touch screen, such as display unit 151, using any of a variety of touch methods. Examples of such touch methods include a resistive type, a capacitive type, an infrared type, and a magnetic field type, among others.

As one example, the touch sensor may be configured to convert changes of pressure applied to a specific part of the display unit 151, or convert capacitance occurring at a specific part of the display unit 151, into electric input signals. The touch sensor may also be configured to sense not only a touched position and a touched area, but also touch pressure and/or touch capacitance. A touch object is generally used to apply a touch input to the touch sensor. Examples of typical touch objects include a finger, a touch pen, a stylus pen, a pointer, or the like.

When a touch input is sensed by a touch sensor, corresponding signals may be transmitted to a touch controller. The touch controller may process the received signals, and then transmit corresponding data to the controller 180. Accordingly, the controller 180 may sense which region of the display unit 151 has been touched. Here, the touch controller may be a component separate from the controller 180, the controller 180, and combinations thereof.

In some embodiments, the controller 180 may execute the same or different controls according to a type of touch object that touches the touch screen or a touch key provided in addition to the touch screen. Whether to execute the same or different control according to the object which provides a touch input may be decided based on a current operating state of the mobile terminal 100 or a currently executed application program, for example.

The touch sensor and the proximity sensor may be implemented individually, or in combination, to sense various types of touches. Such touches includes a short (or tap) touch, a long touch, a multi-touch, a drag touch, a flick touch, a pinch-in touch, a pinch-out touch, a swipe touch, a hovering touch, and the like.

If desired, an ultrasonic sensor may be implemented to recognize position information relating to a touch object using ultrasonic waves. The controller 180, for example, may calculate a position of a wave generation source based on information sensed by an illumination sensor and a plurality of ultrasonic sensors. Since light is much faster than ultrasonic waves, the time for which the light reaches the optical sensor is much shorter than the time for which the ultrasonic wave reaches the ultrasonic sensor. The position of the wave generation source may be calculated using this fact. For instance, the position of the wave generation source may be calculated using the time difference from the time that the ultrasonic wave reaches the sensor based on the light as a reference signal.

The camera 121 typically includes at least one a camera sensor (CCD, CMOS etc.), a photo sensor (or image sensors), and a laser sensor.

Implementing the camera 121 with a laser sensor may allow detection of a touch of a physical object with respect to a 3D stereoscopic image. The photo sensor may be laminated on, or overlapped with, the display device. The photo sensor may be configured to scan movement of the physical object in proximity to the touch screen. In more detail, the photo sensor may include photo diodes and transistors at rows and columns to scan content received at the photo sensor using an electrical signal which changes according to the quantity of applied light. Namely, the photo sensor may calculate the coordinates of the physical object according to variation of light to thus obtain position information of the physical object.

The display unit 151 is generally configured to output information processed in the mobile terminal 100. For example, the display unit 151 may display execution screen information of an application program executing at the mobile terminal 100 or user interface (UI) and graphic user interface (GUI) information in response to the execution screen information.

In some embodiments, the display unit 151 may be implemented as a stereoscopic display unit for displaying stereoscopic images. A typical stereoscopic display unit may employ a stereoscopic display scheme such as a stereoscopic scheme (a glass scheme), an auto-stereoscopic scheme (glassless scheme), a projection scheme (holographic scheme), or the like.

The audio output module 152 is generally configured to output audio data. Such audio data may be obtained from any of a number of different sources, such that the audio data may be received from the wireless communication unit 110 or may have been stored in the memory 170. The audio data may be output during modes such as a signal reception mode, a call mode, a record mode, a voice recognition mode, a broadcast reception mode, and the like. The audio output module 152 can provide audible output related to a particular function (e.g., a call signal reception sound, a message reception sound, etc.) performed by the mobile terminal 100. The audio output module 152 may also be implemented as a receiver, a speaker, a buzzer, or the like.

A haptic module 153 can be configured to generate various tactile effects that a user feels, perceive, or otherwise experience. A typical example of a tactile effect generated by the haptic module 153 is vibration. The strength, pattern and the like of the vibration generated by the haptic module 153 can be controlled by user selection or setting by the controller. For example, the haptic module 153 may output different vibrations in a combining manner or a sequential manner.

Besides vibration, the haptic module 153 can generate various other tactile effects, including an effect by stimulation such as a pin arrangement vertically moving to contact skin, a spray force or suction force of air through a jet orifice or a suction opening, a touch to the skin, a contact of an electrode, electrostatic force, an effect by reproducing the sense of cold and warmth using an element that can absorb or generate heat, and the like.

The haptic module 153 can also be implemented to allow the user to feel a tactile effect through a muscle sensation such as the user’s fingers or arm, as well as transferring the tactile effect through direct contact. Two or more haptic modules 153 may be provided according to the particular configuration of the mobile terminal 100.

An optical output module 154 can output a signal for indicating an event generation using light of a light source. Examples of events generated in the mobile terminal 100 may include message reception, call signal reception, a missed call, an alarm, a schedule notice, an email reception, information reception through an application, and the like.

A signal output by the optical output module 154 may be implemented in such a manner that the mobile terminal emits monochromatic light or light with a plurality of colors. The signal output may be terminated as the mobile terminal senses that a user has checked the generated event, for example.

The interface unit 160 serves as an interface for external devices to be connected with the mobile terminal 100. For example, the interface unit 160 can receive data transmitted from an external device, receive power to transfer to elements and components within the mobile terminal 100, or transmit internal data of the mobile terminal 100 to such external device. The interface unit 160 may include wired or wireless headset ports, external power supply ports, wired or wireless data ports, memory card ports, ports for connecting a device having an identification module, audio input/output (I/O) ports, video I/O ports, earphone ports, or the like.

The identification module may be a chip that stores various information for authenticating authority of using the mobile terminal 100 and may include a user identity module (UIM), a subscriber identity module (SIM), a universal subscriber identity module (USIM), and the like. In addition, the device having the identification module (also referred to herein as an “identifying device”) may take the form of a smart card. Accordingly, the identifying device can be connected with the terminal 100 via the interface unit 160.

When the mobile terminal 100 is connected with an external cradle, the interface unit 160 can serve as a passage to allow power from the cradle to be supplied to the mobile terminal 100 or may serve as a passage to allow various command signals input by the user from the cradle to be transferred to the mobile terminal there through. Various command signals or power input from the cradle may operate as signals for recognizing that the mobile terminal is properly mounted on the cradle.

The memory 170 can store programs to support operations of the controller 180 and store input/output data (for example, phonebook, messages, still images, videos, etc.). The memory 170 may store data related to various patterns of vibrations and audio which are output in response to touch inputs on the touch screen.

The memory 170 may include one or more types of storage mediums including a Flash memory, a hard disk, a solid state disk, a silicon disk, a multimedia card micro type, a card-type memory (e.g., SD or DX memory, etc), a Random Access Memory (RAM), a Static Random Access Memory (SRAM), a Read-Only Memory (ROM), an Electrically Erasable Programmable Read-Only Memory (EEPROM), a Programmable Read-Only memory (PROM), a magnetic memory, a magnetic disk, an optical disk, and the like. The mobile terminal 100 may also be operated in relation to a network storage device that performs the storage function of the memory 170 over a network, such as the Internet.

The controller 180 may typically control the general operations of the mobile terminal 100. For example, the controller 180 may set or release a lock state for restricting a user from inputting a control command with respect to applications when a status of the mobile terminal meets a preset condition.

The controller 180 can also perform the controlling and processing associated with voice calls, data communications, video calls, and the like, or perform pattern recognition processing to recognize a handwriting input or a picture drawing input performed on the touch screen as characters or images, respectively. In addition, the controller 180 can control one or a combination of those components in order to implement various exemplary embodiments disclosed herein.

The power supply unit 190 receives external power or provide internal power and supply the appropriate power required for operating respective elements and components included in the mobile terminal 100. The power supply unit 190 may include a battery, which is typically rechargeable or be detachably coupled to the terminal body for charging.

The power supply unit 190 may include a connection port. The connection port may be configured as one example of the interface unit 160 to which an external charger for supplying power to recharge the battery is electrically connected.

As another example, the power supply unit 190 may be configured to recharge the battery in a wireless manner without use of the connection port. In this example, the power supply unit 190 can receive power, transferred from an external wireless power transmitter, using at least one of an inductive coupling method which is based on magnetic induction or a magnetic resonance coupling method which is based on electromagnetic resonance.

Various embodiments described herein may be implemented in a computer-readable medium, a machine-readable medium, or similar medium using, for example, software, hardware, or any combination thereof.

Referring now to FIGS. 1B and 1C, the mobile terminal 100 is described with reference to a bar-type terminal body. However, the mobile terminal 100 may alternatively be implemented in any of a variety of different configurations. Examples of such configurations include watch-type, clip-type, glasses-type, or as a folder-type, flip-type, slide-type, swing-type, and swivel-type in which two and more bodies are combined with each other in a relatively movable manner, and combinations thereof. Discussion herein will often relate to a particular type of mobile terminal (for example, bar-type, watch-type, glasses-type, and the like). However, such teachings with regard to a particular type of mobile terminal will generally apply to other types of mobile terminals as well.

The mobile terminal 100 will generally include a case (for example, frame, housing, cover, and the like) forming the appearance of the terminal. In this embodiment, the case is formed using a front case 101 and a rear case 102. Various electronic components are incorporated into a space formed between the front case 101 and the rear case 102. At least one middle case may be additionally positioned between the front case 101 and the rear case 102.

The display unit 151 is shown located on the front side of the terminal body to output information. As illustrated, a window 151a of the display unit 151 may be mounted to the front case 101 to form the front surface of the terminal body together with the front case 101.

In some embodiments, electronic components may also be mounted to the rear case 102. Examples of such electronic components include a detachable battery 191, an identification module, a memory card, and the like. Rear cover 103 is shown covering the electronic components, and this cover may be detachably coupled to the rear case 102. Therefore, when the rear cover 103 is detached from the rear case 102, the electronic components mounted to the rear case 102 are externally exposed.

As illustrated, when the rear cover 103 is coupled to the rear case 102, a side surface of the rear case 102 is partially exposed. In some cases, upon the coupling, the rear case 102 may also be completely shielded by the rear cover 103. In some embodiments, the rear cover 103 may include an opening for externally exposing a camera 121b or an audio output module 152b.

The

cases

101, 102, 103 may be formed by injection-molding synthetic resin or may be formed of a metal, for example, stainless steel (STS), aluminum (Al), titanium (Ti), or the like.

As an alternative to the example in which the plurality of cases form an inner space for accommodating components, the mobile terminal 100 may be configured such that one case forms the inner space. In this example, a mobile terminal 100 having a uni-body is formed in such a manner that synthetic resin or metal extends from a side surface to a rear surface.

If desired, the mobile terminal 100 may include a waterproofing unit (not shown) for preventing introduction of water into the terminal body. For example, the waterproofing unit may include a waterproofing member which is located between the window 151a and the front case 101, between the front case 101 and the rear case 102, or between the rear case 102 and the rear cover 103, to hermetically seal an inner space when those cases are coupled.

FIGS. 1B and 1C depict certain components as arranged on the mobile terminal. However, it is to be understood that alternative arrangements are possible and within the teachings of the instant disclosure. Some components may be omitted or rearranged. For example, the first manipulation unit 123a may be located on another surface of the terminal body, and the second audio output module 152b may be located on the side surface of the terminal body.

The display unit 151 outputs information processed in the mobile terminal 100. The display unit 151 may be implemented using one or more suitable display devices. Examples of such suitable display devices include a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT-LCD), an organic light emitting diode (OLED), a flexible display, a 3-dimensional (3D) display, an e-ink display, and combinations thereof.

The display unit 151 may be implemented using two display devices, which can implement the same or different display technology. For instance, a plurality of the display units 151 may be arranged on one side, either spaced apart from each other, or these devices may be integrated, or these devices may be arranged on different surfaces.

The display unit 151 may also include a touch sensor which senses a touch input received at the display unit. When a touch is input to the display unit 151, the touch sensor may be configured to sense this touch and the controller 180, for example, may generate a control command or other signal corresponding to the touch. The content which is input in the touching manner may be a text or numerical value, or a menu item which can be indicated or designated in various modes.

The touch sensor may be configured in a form of a film having a touch pattern, disposed between the window 151a and a display on a rear surface of the window 151a, or a metal wire which is patterned directly on the rear surface of the window 151a. Alternatively, the touch sensor may be integrally formed with the display. For example, the touch sensor may be disposed on a substrate of the display or within the display.

The display unit 151 may also form a touch screen together with the touch sensor. Here, the touch screen may serve as the user input unit 123 (see FIG. 1A). Therefore, the touch screen may replace at least some of the functions of the first manipulation unit 123a.

The first audio output module 152a may be implemented in the form of a speaker to output voice audio, alarm sounds, multimedia audio reproduction, and the like.

The window 151a of the display unit 151 will typically include an aperture to permit audio generated by the first audio output module 152a to pass. One alternative is to allow audio to be released along an assembly gap between the structural bodies (for example, a gap between the window 151a and the front case 101). In this case, a hole independently formed to output audio sounds may not be seen or is otherwise hidden in terms of appearance, thereby further simplifying the appearance and manufacturing of the mobile terminal 100.

The optical output module 154 can be configured to output light for indicating an event generation. Examples of such events include a message reception, a call signal reception, a missed call, an alarm, a schedule notice, an email reception, information reception through an application, and the like. When a user has checked a generated event, the controller can control the optical output unit 154 to stop the light output.

The first camera 121a can process image frames such as still or moving images obtained by the image sensor in a capture mode or a video call mode. The processed image frames can then be displayed on the display unit 151 or stored in the memory 170.

The first and second manipulation units 123a and 123b are examples of the user input unit 123, which may be manipulated by a user to provide input to the mobile terminal 100. The first and second manipulation units 123a and 123b may also be commonly referred to as a manipulating portion, and may employ any tactile method that allows the user to perform manipulation such as touch, push, scroll, or the like. The first and second manipulation units 123a and 123b may also employ any non-tactile method that allows the user to perform manipulation such as proximity touch, hovering, or the like.

FIG. 1B illustrates the first manipulation unit 123a as a touch key, but possible alternatives include a mechanical key, a push key, a touch key, and combinations thereof.

Input received at the first and second manipulation units 123a and 123b may be used in various ways. For example, the first manipulation unit 123a may be used by the user to provide an input to a menu, home key, cancel, search, or the like, and the second manipulation unit 123b may be used by the user to provide an input to control a volume level being output from the first or second audio output modules 152a or 152b, to switch to a touch recognition mode of the display unit 151, or the like.

As another example of the user input unit 123, a rear input unit (not shown) may be located on the rear surface of the terminal body. The rear input unit can be manipulated by a user to provide input to the mobile terminal 100. The input may be used in a variety of different ways. For example, the rear input unit may be used by the user to provide an input for power on/off, start, end, scroll, control volume level being output from the first or second audio output modules 152a or 152b, switch to a touch recognition mode of the display unit 151, and the like. The rear input unit may be configured to permit touch input, a push input, or combinations thereof.

The rear input unit may be located to overlap the display unit 151 of the front side in a thickness direction of the terminal body. As one example, the rear input unit may be located on an upper end portion of the rear side of the terminal body such that a user can easily manipulate it using a forefinger when the user grabs the terminal body with one hand. Alternatively, the rear input unit can be positioned at most any location of the rear side of the terminal body.

Embodiments that include the rear input unit may implement some or all of the functionality of the first manipulation unit 123a in the rear input unit. As such, in situations where the first manipulation unit 123a is omitted from the front side, the display unit 151 can have a larger screen.

As a further alternative, the mobile terminal 100 may include a finger scan sensor which scans a user’s fingerprint. The controller 180 can then use fingerprint information sensed by the finger scan sensor as part of an authentication procedure. The finger scan sensor may also be installed in the display unit 151 or implemented in the user input unit 123.

The microphone 122 is shown located at an end of the mobile terminal 100, but other locations are possible. If desired, multiple microphones may be implemented, with such an arrangement permitting the receiving of stereo sounds.

The interface unit 160 may serve as a path allowing the mobile terminal 100 to interface with external devices. For example, the interface unit 160 may include one or more of a connection terminal for connecting to another device (for example, an earphone, an external speaker, or the like), a port for near field communication (for example, an Infrared Data Association (IrDA) port, a Bluetooth port, a wireless LAN port, and the like), or a power supply terminal for supplying power to the mobile terminal 100. The interface unit 160 may be implemented in the form of a socket for accommodating an external card, such as Subscriber Identification Module (SIM), User Identity Module (UIM), or a memory card for information storage.

The second camera 121b is shown located at the rear side of the terminal body and includes an image capturing direction that is substantially opposite to the image capturing direction of the first camera unit 121a. If desired, second camera 121a may alternatively be located at other locations, or made to be moveable, in order to have a different image capturing direction from that which is shown.

The second camera 121b can include a plurality of lenses arranged along at least one line. The plurality of lenses may also be arranged in a matrix configuration. The cameras may be referred to as an “array camera.” When the second camera 121b is implemented as an array camera, images may be captured in various manners using the plurality of lenses and images with better qualities.

As shown in FIG. 1C, a flash 124 is shown adjacent to the second camera 121b. When an image of a subject is captured with the camera 121b, the flash 124 may illuminate the subject.

As shown in FIG. 1B, the second audio output module 152b can be located on the terminal body. The second audio output module 152b may implement stereophonic sound functions in conjunction with the first audio output module 152a, and may be also used for implementing a speaker phone mode for call communication.

At least one antenna for wireless communication may be located on the terminal body. The antenna may be installed in the terminal body or formed by the case. For example, an antenna which configures a part of the broadcast receiving module 111 may be retractable into the terminal body. Alternatively, an antenna may be formed using a film attached to an inner surface of the rear cover 103, or a case that includes a conductive material.

A power supply unit 190 for supplying power to the mobile terminal 100 may include a battery 191, which is mounted in the terminal body or detachably coupled to an outside of the terminal body. The battery 191 may receive power via a power source cable connected to the interface unit 160. Also, the battery 191 can be recharged in a wireless manner using a wireless charger. Wireless charging may be implemented by magnetic induction or electromagnetic resonance.

The rear cover 103 is shown coupled to the rear case 102 for shielding the battery 191, to prevent separation of the battery 191, and to protect the battery 191 from an external impact or from foreign material. When the battery 191 is detachable from the terminal body, the rear case 103 may be detachably coupled to the rear case 102.

An accessory for protecting an appearance or assisting or extending the functions of the mobile terminal 100 can also be provided on the mobile terminal 100. As one example of an accessory, a cover or pouch for covering or accommodating at least one surface of the mobile terminal 100 may be provided. The cover or pouch may cooperate with the display unit 151 to extend the function of the mobile terminal 100. Another example of the accessory is a touch pen for assisting or extending a touch input to a touch screen.

The mobile terminal 100 according to the embodiment of the present disclosure communicates with a moving means 200, and controls functions of the moving means 200. Here, the moving means 200 may be formed to be movable on the ground by including a plurality of wheels.

The moving means 200 may include a camera (not shown) to photograph images in traveling thereof. Also, the moving means 200 may be formed such that the main body of the mobile terminal 100 can be mounted thereto. In this case, images may be photographed through the camera 121 provided in the main body of the mobile terminal 100 while the moving means 200 is traveling.

The camera described in this specification, although there is no separate description, may mean the camera (not shown) provided in the moving means 200 and/or the camera 121 provided in the main body of the mobile terminal 100.

The mobile terminal 100 according to the embodiment of the present disclosure may generate information on a traveling path of the moving means 200, to control the moving means 200 to move along the traveling path. This will be described in detail.

FIG. 2A is a flowchart illustrating a control method of the mobile terminal according to an embodiment of the present disclosure, and FIG. 2B is a conceptual view illustrating the control method of FIG. 2A.

Referring to FIGS. 2A and 2B, the controller 180 outputs an image received through the camera 121 on the touch screen 151 formed in the main body of the mobile terminal 100 (S210).

More specifically, an application for controlling the moving means 200 may be installed in the mobile terminal 100. The controller 180 may output an icon 210a of the application in a home screen page 210 of the touch screen 151. The controller 180 executes the application, based on a touch input applied to the icon 210a.

If the application is executed, a screen including an image received from the camera 121 is output on the touch screen 151. Here, the image may be a preview image received in real time from the camera 121.

Alternatively, the controller 180 may perform control related to photographing, based on a user’s request. The user’s request may be input in various forms to the mobile terminal. As an example, the controller may perform the control related to the photographing, based on a predetermined posture of the main body.

As another example, a virtual button 220a related to the photographing may be output on an execution screen 220 of the application. If a touch is applied to the virtual button 220a, a preview image being output on the screen at the moment when the touch is applied to the virtual button 220a may be stored as a photographing image in a memory. After the photographing is performed, a preview image may be again output on the execution screen of the application, or the photographing image stored in the memory may be output on the execution screen of the application.

The image described in step S210 may mean a preview image received in real time through the camera 121 and/or a photographing image stored in the memory.

Meanwhile, the image is an image that performs the function of a guide for generating a traveling path, and distinguished from an image photographed while the moving means 200 is moving along the traveling path. Thus, in this specification, the image is referred to as a ‘guide image 220.’

Also, in this specification, a place corresponding to the ‘guide image 220’ is referred to as a ‘moving target area.’ More specifically, as shown in FIG. 2B, when the guide image is input by the camera 121 provided in the main body of the mobile terminal 100, the moving target area may be a peripheral area of a place at which a user is located. Meanwhile, although not shown in this figure, when the guide image 220 is input by the camera separately provided in the moving means 200 as described above, the moving target area may be a peripheral area of a place at which the moving means 200 is located.

Hereinafter, the guide image 220 will be described as one photographed by the camera 121 provided in the main body of the mobile terminal 100 in a state in which the main body of the mobile terminal 100 is held by the user.

As shown in FIGS. 2A and 2B, the controller 180 senses a touch applied on the touch screen 151 (S220).

The controller 180 forms a control command on a traveling path of the moving means 200, based on the touch. More specifically, the traveling path may include an area corresponding to a portion to which the touch is applied in the moving target area corresponding to the image (S230).

More specifically, the traveling path may be generated based on position information of at least one point on the traveling path, or generated based on information of at least one of the relative position, size, and shape of a touch trace in the image.

A control method of generating a traveling path based on location information will be described in detail later with reference to FIGS. 3A to 3C. Also, a control method of generating a traveling path based on information of at least one of the relative position, size, and shape of a touch trace in an image will be described in detail later with reference to FIGS. 4A and 4B.

If the main body of the mobile terminal 100 is mounted to the moving means 200, the controller 180 controls the moving means 200 to move along the traveling path (S240).

More specifically, if the main body of the mobile terminal 100 is mounted to the moving means 200, the moving means 200 may start moving without any separate control command. That is, if a predetermined time (a few seconds) elapses after the mounting of the main body of the mobile terminal 100 to the moving means 200 is completed, the moving means 200 may start moving.

Alternatively, if a switch (not shown) separately provided in the moving means 200 is turned on after the main body of the mobile terminal 100 is mounted to the moving means 200, the moving means 200 may start moving. Alternatively, if a touch is applied on the touch screen 151 after the main body of the mobile terminal 100 is mounted to the moving means 200, the moving means 200 may start moving. Meanwhile, the main body of the mobile terminal 100 is not mounted to the moving means 200, and a control command related to the traveling path may be transmitted to the moving means 200 such that only the moving means 200 moves.

Hereinafter, in the present disclosure, a case where the touch applied on the touch screen 151 is a drag touch so as to generate a traveling path will be described as an example. However, the present disclosure is not limited thereto. For example, if a plurality of tap touches are sensed in a plurality of areas on the touch screen 151, a virtual line obtained by connecting the plurality of tap touches may be similarly considered as a trace corresponding to a touch input.

Referring to FIG. 2, when a drag touch is input to an image, the controller 180 controls the moving means 200 to move along an area corresponding to the trace of the drag touch in a moving target area corresponding to the image. In this case, the moving means 200 may move from a point (hereinafter, referred to as a start point P1’) corresponding to a position P1 at which the drag touch starts to a point (hereinafter, referred to as an end point P2’) corresponding to a position P2 at which the drag touch is ended.

Meanwhile, as shown in FIG. 2B, when the initial position P3’ of the moving means 200 does not correspond to the start point P1’, the moving means 200 may move to the start point P1’ and then move along an area corresponding to the trace of the drag touch.

Meanwhile, in the present disclosure, image photographing may be performed through the camera while the moving means 200 is moving along the area corresponding to the trace of the drag touch. This will be described later with reference to FIGS. 5A and 5B.

FIGS. 3A and 3B are flowcharts illustrating a control method of the mobile terminal that generates a traveling path according to an embodiment of the present disclosure, and FIG. 3C is a conceptual view illustrating the control method of FIGS. 3A and 3B.

Referring to FIG. 3A, if a drag touch for generating a traveling touch is applied on the touch screen 151, the controller 180 calculates position information of at least one point of an area corresponding to the trace of the drag touch in a moving target area.

Hereinafter, the control method of the mobile terminal will be described based on a control method of calculating position information on a start point in an area corresponding to the trace of the drag touch. It will be apparent that, position information on the other points may be calculated through the control method, as well as the start point in the area corresponding to the trace of the drag touch. In this case, the moving means 200 may travel along a traveling path, based on the plurality of calculated position information.

Alternatively, after only position information of one point (e.g., a start point in the area corresponding to the trace of the drag touch is calculated through the control method, the other traveling may be performed by a control method according to another embodiment to be described with reference to FIG. 4A.

Referring to FIG. 3A, the controller 180 detects information on a current position information K1 of the main body of the mobile terminal 100 (S310). Specifically, the controller 180 may detect the in formation on the current position K1 of the main body of the mobile terminal 100 by using the wireless communication unit 110 provided in the main body of the mobile terminal 100.

The wireless communication unit 110 includes a position information module 115. The position information module 115 is a module for acquiring a position (or current position) of the mobile terminal, and a global positioning system (GPS) module or a wireless fidelity (WiFi) module is used as a representative example of the position information module 115. As an example, the mobile terminal uses a GPS module, the position of the mobile terminal may be acquired by using a signal transmitted from a GPS satellite. As another example, if the mobile terminal uses a WiFi module, the position of the mobile terminal may be acquired based on information of a wireless access point (AP) transmitting or receiving wireless signals to or from the WiFi module.

More specifically, if the information on the current position K1 of the main body of the mobile terminal is information acquired through the GPS module, the information on the position K1, as shown in FIG. 3C, may include a latitude value and/or a longitude value of a position at which the main body of the mobile terminal 100 is projected onto the ground. Hereinafter, the information on the position K1 is referred to as information of a position at which the main body of the mobile terminal is projected on the ground.

Referring to FIGS. 3A and 3C, the controller 180 detects in formation on a distance S1 from the main body of the mobile terminal 100 to one point of an area corresponding to a traveling path in the moving target area (S320). Specifically, the controller 180 may detect the information on the distance S1 by using a distance sensor, etc., provided in the main body of the mobile terminal 100.

Specifically, the distance sensor may include an ultrasonic sensor, an infrared sensor, an optical sensor, and the like. For example, the ultrasonic sensor may recognize position information of a sensing target by using ultrasonic waves. Meanwhile, the controller 180 may calculate a position of a wave generation source through information sensed from an optical sensor and a plurality of ultrasonic sensors. The position of the wave generation source may be calculated by using a property that light is very faster than ultrasonic waves, i.e., that the time for which light reaches the optical sensor is very faster than the time for which an ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generation source may be calculated by using a difference between the time for which the light as a reference signal reaches the optical sensor and the time for which the ultrasonic wave reaches the ultrasonic sensor.

Meanwhile, although not separately shown in these figures, the information on the distance S1 may be more accurately calculated by applying, to a measurement value of the distance sensor at least one of viewing angle information of the camera, scale information of a guide image, and inclination information of the main body of the mobile terminal.

Meanwhile, referring to FIG. 3B, the controller 180 may correct the information on the distance S1 from the main body of the mobile terminal 100 to the one point corresponding to the traveling path, which is detected by the distance sensor, etc., to be more accurate. Hereinafter, this will be described in detail.

Referring to FIGS. 3B and 3C, as described above, the controller 180 detects a distance S1 from the main body of the mobile terminal 100 to one point of an area corresponding to the traveling path (S321). Also, the controller 180 detects information on a height H1 of the main body of the mobile terminal from the ground by using the distance sensor, etc. (S322). Further, the controller 180 may calculate information on a distance S1’ from the position K1 at which the main body of the mobile terminal is projected onto the ground to one point K2 of the area corresponding to the traveling path by using the distance S1 and the height H1 (S323).

Referring to FIG. 3A, the controller 180 detects information on a position K2 of one point of the area corresponding to the traveling path (S330). Specifically, the controller 180 may calculate the information on the position K2 by using the information on the position K1 at which the main body of the mobile terminal is projected onto the ground and the information on the distance S1 from the main body of the mobile terminal to the one point corresponding to the traveling path. Meanwhile, it will be apparent that the information on the corrected distance S1’ may be used rather than the information on the distance S1.

Meanwhile, the controller 180 may calculate information on a relative direction D1 of the moving target area with respect to the main body of the mobile terminal, based on a posture or angle of the main body of the mobile terminal when an image is photographed. Accordingly, the controller 180 can calculate the information on the position K2 of the area corresponding to the traveling path by using the current position K1 of the main body of the mobile terminal, the relative distance and direction S1 and D1 from the main body of the mobile terminal to the area corresponding to the traveling path.

Referring to FIG. 3A, the controller 180 transmits, to the moving means 200, the information on the calculated position K2 of the one point of the area corresponding to the traveling path (S340).

The controller 180 may acquire information on positions of the other points of the area corresponding to the traveling path through the control method described so far. In other words, the controller 180 may transmit, to the moving means 200, the information on the positions of all the areas corresponding to the traveling path.

Alternatively, the controller 180 may transmit, to the moving means 200, only information on the position of a start point in the area corresponding to the traveling path. In this case, the moving means 200 may moves to the start point by using the information on the position of the start point, and then move through the vector-based control method. Hereinafter, the vector-based control method will be described in detail.

FIG. 4A is a flowchart illustrating a control method (vector-based control method) of the mobile terminal that generates a traveling path according to another embodiment of the present disclosure, and FIG. 4B is a conceptual view illustrating the control method of FIG. 4A.

According to this embodiment, the controller 180 senses an image object 440 corresponding to the moving means 200 in an image (S410). Specifically, the controller 180 may recognize the image object 440 in the image through an algorithm using a predetermined condition of the image object 440.

After that, if a drag touch applied on the touch screen 151 is sensed, the controller 180 calculates at least one of information on a relative magnitude and a relative direction of a touch trace based on the image object 440 in the image (S420).

The controller 180 generates a traveling path of the moving means 200 by applying at least one of the information on the calculated relative magnitude and direction to information on a length and a direction of the moving means 200 (S430).

For example, referring to FIG. 4B, a length l1 of the image object 440 and a length l2 of the touch trace may be calculated on the touch screen 151. Further, a proportional relationship between the length l1 of the image object 440 and the length l2 of the touch trace may be calculated. Accordingly, as the proportional relationship is applied to an actual length l1’ of the moving means 200, an actual length l2’ of the traveling path can be calculated.

Also, referring to FIG. 4B, a direction θ of the touch trace may be calculated based on the front direction (advancing direction) of the image object 440 on the touch screen 151. Accordingly, the traveling direction of the moving means 200 can be determined in the moving target area.

In the above, the example in which information on the traveling path (information on the direction and distance of the traveling path) is calculated based on the relative magnitude and direction of the touch trace with respect to the image object in the image has been described, but the present disclosure is not limited thereto.

That is, in the present disclosure, the traveling path of the moving means 200 may be generated without using any image object on the touch screen 151. For example, the controller 180 may calculate a relative position of the trace of a drag touch with respect to a start position of the drag touch. Further, the controller 180 may generate the traveling path of the moving means 200 by using the calculated relative position.

In the above, it has been described that the traveling path is generated based on information on the position of at least one point on the traveling path or generated based on information on at least one of the relative position, magnitude, and shape of a touch trace in an image. However, the present disclosure is not limited thereto, and the traveling path may be generated by various methods.

More specifically, if a drag touch is applied on the touch screen 151, the controller 180 controls a camera to photograph surroundings while moving along an area corresponding to the trace of the drag touch. This will be described in detail.

In this case, the camera, as described above, may be the camera separately provided in the moving means 200 or the camera of the main body of the mobile terminal, which is mounted to the moving means 200. Specifically, when the main body of the mobile terminal 100 is mounted to the moving means 200, image photographing is performed by at least one of the camera 121 provided in the main body of the mobile terminal 100 and/or the camera separately provided in the moving means 200. Even when the main body of the mobile terminal 100 is not mounted to the moving means 200, the moving means 200 may perform the image photographing by using the camera separately provided therein while moving along a traveling path.

FIG. 5A is a flowchart illustrating a control method of the mobile terminal that photographs surroundings in traveling of the moving means 200 according to an embodiment of the present disclosure, and FIGS. 5B and 5C are conceptual views illustrating the control method of FIG. 5A.

Referring to FIGS. 5A and (a) of FIG. 5B, the controller 180 senses a first touch 550 applied on the touch screen 151 in a state in which a guide image 220 having a moving target area photographed therein is output on the touch screen 151 (S510).

In this case, the guide image 220, as described above, may be a preview image output in real time from the camera and/or an image stored in the memory provided in the main body of the mobile terminal.

Meanwhile, the guide image 220 may include an image object 551 corresponding to a subject.

Referring to FIGS. 5A and (b) of FIG. 5B, the controller 180 senses a second touch 560 applied on the touch screen 151 while the first touch 550 applied on the touch screen 151 is being maintained (S520). In other words, the second touch 560 may be applied while the first touch 550 is being maintained. That is, the second touch 560 may be first released before the first touch 550 is released, or the first touch 550 and the second touch 560 may be substantially simultaneously released. The term ‘substantially simultaneously’ may mean not only exactly the same time but also the same time that may be recognized because the time difference is within a predetermined time reference even though there is a slight time difference.

The second touch 560 may be applied at a position different from the position at which the first touch 550 is applied on the touch screen 151.

Meanwhile, the first and

second touches

550 and 560 may be touches applied in different manners. For example, as shown in FIG. 5B, the first touch 550 may be a long touch and the second touch 560 may be a drag touch.

Referring to FIGS. 5A and 5B, the controller 180 generates a driving path 570 including an area corresponding to a portion at which the second touch 560 is applied (S530). For example, when the second touch 560 is a drag touch, the controller 180 generates the traveling path to correspond to the trace of the drag touch.

If the main body of the mobile terminal 100 is mounted to the moving means 200, information on the traveling path 570 is transmitted to the moving means 200 through wireless communication modules respectively provided in the main body of the mobile terminal 100 and the moving means 200. The moving means 200 moves along the traveling path 570 by using the transmitted information on the traveling path 570.

Referring to FIGS. 5A and (c) of FIG. 5B, the controller 180 controls the camera to photograph a subject 300 corresponding to the image object 551 corresponding to the portion at which the first touch 550 is applied while the moving means 200 is moving along the traveling path (S540). In other words, the controller 180 controls the camera 121 to photograph the subject 300 while the moving means 200 is moving along the traveling path 570. That is, the photographing may be performed when the moving means 200 moves from a start point P1’ to an end point P2’ of the traveling path 570.

More specifically, in step 540, the controller 180 recognizes the image object 551 corresponding to the portion at which the first touch 550 is applied. The recognition of the image object 551 in the image may be performed based on a predetermined method. For example, the controller 180 may recognize the image object 551 by using outline information, color information, etc. of the image object 551, which is distinguished from other areas in the image.

After that, if the moving means 200 starts traveling, the camera provided in the moving means 200 and/or the camera 121 of the main body of the mobile terminal 100 mounted to the moving means 200 start photographing surroundings. In this case, if the previously recognized image object 551 is included in the photographed image, the controller 180 control the camera to photograph the subject 300 corresponding to the image object 551 while the moving means 200 is traveling.

For example, the posture of the camera with respect to the moving means 200 may be changed such that the subject 300 continuously exists within the viewing angle of the camera while the moving means 200 is moving along the traveling path 570. Further, the controller 180 may continuously control the posture of the camera not only such that the camera simply photographs the subject 300 but also such that the image object 551 corresponding to the subject 300 is disposed at the center in the photographed image.

More specifically, although not shown in this figure, a proximity sensor may be provided near the touch screen 151. In this case, a degree of proximity of a touch on the touch screen 151 may be measured. The posture of the camera with respect to the moving means 200 may be controlled based on the degree of proximity of the touch. For example, as the touch comes close to the touch screen 151, the controller 180 may control the main body of the mobile terminal to rotate about one center axis of the moving means 200.

Also, the controller 180 may control the camera to perform auto-focusing on the subject 330 while the moving means 200 is moving along the traveling path. The controller 180 may operate a zoom lens module of the camera such that the subject 300 is focused during photographing, thereby acquiring an image to which a user’s intention is better reflected.

Meanwhile, in FIG. 5B, it is illustrated that the first touch 550 is applied by a thumb of one hand and the second touch 560 is applied by an index finger of the same hand, but the present disclosure is not limited thereto. For example, the first and

second touches

550 and 560 may be applied by index fingers of the left and right hands, respectively.

The controller 180 may control the camera to perform various functions in image photographing, based on which finger of which hand each of the first and second touches is applied by.

For example, not shown in this figure, when the first touch is applied by the index and middle fingers of the left hand and the second touch is apply by the index finger of the right hand, the controller 180 may control the camera such that the image photographing is performed as high-resolution photographing.

Meanwhile, the controller 180 may control the moving means 200 and the camera to always photograph surroundings in traveling of the moving means 200, based on a user’s request. Alternatively, while the moving means 200 is traveling along the traveling path, the controller 180 may perform image photographing only while the moving means 200 is passing an arbitrary section of the traveling path, and not perform image photographing in the other section. In this case, the arbitrary section may be previously set based on a user’s selection.

Meanwhile, as described above, if a drag touch is sensed on the touch screen 151 in the state in which the image is output, the controller 180 may generate a traveling path including an area corresponding to the trace of the sensed touch.

Further, the controller 180 may control the moving means 200 such that the traveling speed of the moving means 200 is changed depending on an input speed of the drag touch. This will be described in detail.

Specifically, if a drag touch is sensed, the controller 180 may calculate an input speed of the drag touch, based on the length of a trace dragged within a predetermined time. The predetermined time is properly adjusted, so that it is possible to calculate a touch input speed changed while the drag touch is being applied.

Further, the controller 180 may calculate information on a traveling speed of the moving means 200, corresponding to the calculated touch input speed. The touch input speed and the traveling speed of the moving means 200 do not necessarily correspond to each other. However, as the touch input speed is instantaneously increased, the traveling speed of the moving means 200 is preferably increased. For example, the traveling speed may be increased in proportion to the touch input speed. However, the present disclosure is not limited thereto, and the relationship between the traveling speed and the touch input speed may vary.

Meanwhile, according to the present disclosure, if a drag touch is sensed on the touch screen 151 in a state in which a guide image 220 is output, the controller 180 may output, on the touch screen 151, a graphic object 600 corresponding to the trace of the sensed touch.

Hereinafter, the graphic object 600 means an image output on the touch screen 151 to correspond to the trace of a drag touch applied on the touch screen 151 in the state in which the guide image 220 is output. Meanwhile, the graphic object 600 may be output in real time while the drag touch is being input or output after the inputting of the drag touch is completed.

According to the present disclosure, the controller 180 may express the graphic object in different colors, based on an input speed of the drag touch. This will be described in detail.

FIGS. 6A and 6B are conceptual views illustrating a control method of outputting a graphic object, based on an input speed of a drag touch.

Referring to FIG. 6A, when the input speed of the drag touch is changed depending on a trace of the drag touch, the controller 180 may output the graphic object in various colors, based on the input speed of the drag touch.

For example, when the drag touch is input at a relatively fast speed in sections a and c in the trace thereof and input at a relatively slow speed in section b in the trace thereof, the graphic object may be output in a first color in the sections a and c thereof, and output in a second color in the section b thereof (e.g., the first color is green and the second color is red). Accordingly, before a user allows the moving means 200 to travel, the user can previously plan a traveling speed corresponding to a traveling path, and easily confirm the planned traveling speed.

If the main body of the mobile terminal 100 is mounted to the moving means 200 after the inputting of the drag touch on the touch screen 151 is completed, the moving means 200 travels along the trace of the drag touch, based on a planned traveling speed.

For example, the moving means 200 may travel at a relatively fast speed when passing sections A and C of the traveling path, corresponding to the sections a and c of the graphic object. On the other hand, the moving means 200 may travel at a relatively slow speed when passing section B of the traveling path, corresponding to the section b of the graphic object.

In the above, it has been described that the traveling speed of the moving means 200 is adjusted based on an initial input speed of the drag touch for generating the traveling path. However, after the inputting of the drag touch for generating the traveling path is completed, a separate drag touch for adjusting the traveling speed may be applied to adjust the traveling speed. This will be described in detail with reference to FIG. 6B.

Referring to FIG. 6B, after the inputting of a first drag touch 610 is completed, image objects 620a, 620b, 620c, and 620d for adjusting the traveling speed may be output on the touch screen 151, based on a user’s selection.

The image objects 620a, 620b, 620c, and 620d may have different colors. The image objects 620a, 620b, 620c, and 620d may be previously set to correspond to information on different speeds of the moving means 200, respectively.

Meanwhile, only four

image objects

620a, 620b, 620c, and 620d are illustrated in FIG. 6B. However, the present disclosure is not limited thereto, and various numbers of image objects may be output on the touch screen 151.

Referring to FIG. 6B, if a touch is applied to any one 620a among the image objects, and a second drag touch 630 is applied on the first drag touch 610, a portion at which the second drag touch 630 is applied on the first drag touch 610 is output in a color corresponding to the image object 620a.

Through the above-described method, a traveling speed corresponding to the traveling path may be previously planned before the moving means 200 travels. Thus, the user can easily recognize the planned traveling speed through graphic objects output in various colors.

Meanwhile, according to the present disclosure, if a predetermined touch is input to the graphic object, the controller 180 may perform a predetermined function related to the predetermined touch. This will be described in detail with reference to FIGS. 7A to 7C.

FIG. 7A is a conceptual view illustrating a control method of performing a function related to zoom-in/out adjustment of a camera when a predetermined touch applied to a graphic object is sensed.

Referring to FIG. 7A, if a drag touch is sensed in an image including a moving target area, a graphic object 710 corresponding to the drag touch is output. More specifically, the graphic object 710 may be output while the drag touch is being applied and/or after the application of the drag touch is completed.

In this embodiment, if a predetermined touch is applied on the graphic object 710 after the generation of the graphic object 710 is completed, an image object 720 related to zoom-in/out adjustment of the camera is output near position a at which the predetermined touch is sensed.

For example, as shown in FIG. 7A, if a long touch is applied at the position a on the graphic object 710, the image object 720 related to the zoon in/out adjustment of the camera is output near the position a at which the long touch is sensed. Here, the long touch may mean a touch continuously applied at the same position on the touch screen 151 for a predetermined time.

The image object 720 related to the zoom-in/out adjustment may be output in the form of a zoom adjustment bar. For example, if a drag touch 730 corresponding to that the zoom adjustment bar is moved up is applied, the controller 180 may control a zoom module of the camera to perform a zoom in from a reference zoom. On the other hand, if a drag touch corresponding to that the zoom adjustment bar is moved down is applied, the controller 180 may control the zoom module of the camera to perform a zoom out from the reference zoom.

If the main body of the mobile terminal 100 is mounted to the moving means 200 after the drag touch related to the zoom-in/out adjustment is released, the moving means 200 moves along a traveling path as described above. When the moving means 200 passes position A of the traveling path, corresponding to the position a of the graphic object 710, the controller 180 may control the zoom module of the camera to perform a predetermined zoom in.

Meanwhile, in FIG. 7A, only the case where the long touch is applied at the position a on the graphic object is illustrated, but the present disclosure is not limited thereto. For example, the long touch may be replaced with a short touch.

Alternatively, although not shown in this figure, a drag touch (hereinafter, referred to as a second drag touch) different from a drag touch (hereinafter, referred to as a first drag touch) for generating the graphic object 710 may be applied in a predetermined section on the graphic object 710. In this case, the degree of zoom in/out may be adjusted while the moving means 200 is passing an area corresponding to a trace of the second drag touch.

Meanwhile, in the present disclosure, movement and/or correction of the traveling path may be performed by moving and/or correcting the graphic object 710 corresponding to the trace of the drag touch even after the inputting of the drag touch for generating the traveling path is released. This will be described in detail.

FIG. 7B is a conceptual view illustrating a control method related to movement of the graphic object.

Referring to FIG. 7B, if the inputting of a drag touch (hereinafter, referred to as a first drag touch) for generating a traveling path is completed, a graphic object 710 corresponding to the trace of the first drag touch is output on the touch screen 151. If another drag touch (hereinafter, refereed to as a second drag touch) of which inputting is started is applied on the graphic object 710, the graphic object 710 is moved based on a position (position a) at which the inputting of the second drag touch is completed.

More specifically, the graphic object 710 is moved on the touch screen 151, based on the trace of the second drag touch, while the inputting of the second drag touch is being applied. Accordingly, a user can visually recognize the movement of the graphic object 710.

If the main body of the mobile terminal 100 is mounted to the moving means 200 after the second drag touch is released, the moving means 200 moves along a traveling path corresponding to the moved graphic object 710. In other words, the controller 170 generates a traveling path, based on the final position of the graphic object 710, and information on the traveling path is transmitted to the moving means 200 when the main body of the mobile terminal 100 is mounted to the moving means 200.

FIG. 7C is a conceptual view illustrating a control method related to correction of the graphic object.

Referring to FIG. 7C, if the inputting of a drag touch for generating a traveling path is completed, the controller 180 may output, on the touch screen 151, a graphic object 710 corresponding to the trace of the drag touch. As described above, if a predetermined touch is applied to the graphic object 710, the controller 180 may perform a predetermined function related to the predetermined touch.

In this embodiment, if a tap touch is applied at a position corresponding to the graphic object 710 is applied on the touch screen 151, image objects 750a and 750b for changing the size or shape of the graphic object 710 may be output at edges of the graphic object 710. Meanwhile, in FIG. 7C, it is illustrated that the image objects 750a and 750b are output at both ends of the graphic object 710, but the present disclosure is not limited thereto. That is, the image objects 750a and 750b may be output at various positions near the graphic object 710.

If another drag touch using, as a start point, a position corresponding to the image object 750b is applied after the image objects 750a and 750b are output, the size or shape of the graphic object 710 may be changed based on an end point 750b’ of the drag touch.

Also, the controller 180 may generate a traveling path including an area corresponding to the change graphic object 710 in the moving target area. After that, if the main body of the mobile terminal 100 is mounted to the moving means 200, information on the traveling path is transmitted from the main body of the mobile terminal 100 to the moving means 200. Thus, the moving means 200 can move along a traveling path 740 corresponding to the change graphic object 710.

In the above, the control methods of changing the traveling path before the moving means 200 travels along the traveling path have been described. Meanwhile, even after the moving means 200 travels along a traveling path, the traveling path may be corrected such that the moving means 200 again travels along the corrected traveling path.

Meanwhile, in the present disclosure, as described above, the photographing of images may be performed through the camera while the moving means 200 is traveling along a traveling path. If the photographing of the images is ended, the photographed images may be reproduced in the form of a moving image. Accordingly, a user can perform feedback on the photographed images while watching the moving image.

FIG. 8A is a conceptual view illustrating a control method of applying a feedback command to a photographed image.

Referring to FIG. 8A, if the main body of the mobile terminal 100 is separated from the moving means 200 after the photographing of a moving image through the camera is completed while the moving means 200 is moving, the photographed moving image may be output in one area of the touch screen.

If a touch is applied to the photographed moving image is sensed while the moving image is being reproduced, the controller 180 may display, on a graphic object 710, a position at which an image output at the moment when the touch is sensed is photographed, by using a separate indicator 820.

Further, if a predetermined touch is applied to the output graphic object, the controller 180 may perform a predetermined function.

For example, as described above, if a long touch is applied at the displayed position, a zoom adjustment bar is output near the position at which the long touch is input. As a user applied a touch to the zoom adjustment bar, the degree of zoom-in/out adjustment of the camera may be changed at the displayed position a. That is, if the main body of the mobile terminal 100 is again mounted to the moving means 200 after the zoom-in/out adjustment is completed, the camera may again perform image photographing by reflecting the changed degree of zoom-in/out adjustment while the moving means 200 is passing an area corresponding to the position a.

Meanwhile, according to the present disclosure, while the moving means 200 is traveling along the traveling path, the image photographed by the camera may be stored together with information on the traveling path. This will be described in detail with reference to FIG. 8B.

FIG. 8B is a conceptual view illustrating a control method of, when a traveling path is generated, outputting a previously stored photographing image when the generated traveling path is included in a previously stored traveling path.

More specifically, if a drag trace for generating a traveling path is input in a state in which a current guide image is output on the touch screen 151, the controller 180 may determined whether an image including at least one portion of the current guide image exists in a previously stored guide image.

When an image including at least one portion of the current guide image exists in the previously stored guide image, the controller 180 may compare current traveling path information corresponding to the current guide image with traveling path information (hereinafter, referred to as past traveling path information) corresponding to the image (hereinafter, referred to as a past guide image).

When at least one portion of the current traveling path information corresponds to at least one portion of the pas traveling path information, the controller 180 may output a photographed image corresponding to the past traveling path information in one area 840 on the touch screen 151.

Meanwhile, an edited image may be output by re-editing the photographed image, based on at least one of information on the drag trace in the current guide image and information of an image object corresponding to a subject.

Accordingly, before the moving means 200 moves, an image to be previously photographed may be output while a drag input for generating a traveling path is being applied to a guide image. Thus, a plan for traveling can be more thoroughly made before the moving means moves.

Various embodiments may be implemented using a machine-readable medium having instructions stored thereon for execution by a processor to perform various methods presented herein. Examples of possible machine-readable mediums include HDD(Hard Disk Drive), SSD(Solid State Disk), SDD(Silicon Disk Drive), ROM, RAM, CD-ROM, a magnetic tape, a floppy disk, an optical data storage device, the other types of storage mediums presented herein, and combinations thereof. If desired, the machine-readable medium may be realized in the form of a carrier wave (for example, a transmission over the Internet). The processor may include the controller 180 of the mobile terminal.
