The processed image frames may be displayed on a display unit 151.
The image frames processed by the camera 121 may be stored in the memory 160 or transmitted via the wireless communication unit 110. Two or more cameras 121 may be provided according to the configuration of the mobile communication terminal.
The microphone 122 may receive sounds (audible data) via a microphone in a phone call mode, a recording mode, a voice recognition mode, and the like, and can process such sounds into audio data. The processed audio (voice) data may be converted for output into a format transmittable to a mobile communication base station via the mobile communication module 112 in case of the phone call mode. The microphone 122 may implement various types of noise canceling (or suppression) algorithms to cancel (or suppress) noise or interference generated in the course of receiving and transmitting audio signals.
The user input unit 130 may generate key input data from commands entered by a user to control various operations of the mobile communication terminal. The user input unit 130 allows the user to enter various types of information, and may include a keypad, a dome switch, a touch pad (e.g., a touch sensitive member that detects changes in resistance, pressure, capacitance, etc. due to being contacted) a jog wheel, a jog switch, and the like.
The sensing unit 140 detects a current status (or state) of the mobile terminal 100 such as an opened or closed state of the mobile terminal 100, a location of the mobile terminal 100, the presence or absence of a user's touch (contact) with the mobile terminal 100 (e.g., touch inputs), the orientation of the mobile terminal 100, an acceleration or deceleration movement and direction of the mobile terminal 100, etc., and generates commands or signals for controlling the operation of the mobile terminal 100. For example, when the mobile terminal 100 is implemented as a slide type mobile phone, the sensing unit 140 may sense whether the slide phone is opened or closed. In addition, the sensing unit 140 can detect whether or not the power supply unit 190 supplies power or whether or not the interface unit 170 is coupled with an external device.
The output unit 150 is configured to provide outputs in a visual, audible, and/or tactile manner (e.g., audio signal, video signal, alarm signal, vibration signal, etc.). The output unit 150 may include the display unit 151, an audio output module 152, an alarm unit 153, a haptic module 154, and the like.
The display unit 151 may display information processed in the mobile terminal 100. For example, when the mobile terminal 100 is in a phone call mode, the display unit 151 may display a User Interface (UI) or a Graphic User Interface (GUI) associated with a call. When the mobile terminal 100 is in a video call mode or a capturing mode, the display unit 151 may display a captured and/or received image or a GUI or a UI.
The display unit 151 may include at least one of a Liquid Crystal Display (LCD), a Thin Film Transistor-LCD (TFT-LCD), an Organic Light Emitting Diode (OLED) display, a flexible display, a three-dimensional (3D) display, and an e-ink display.
Some of these displays may be configured to be transparent so that outside may be seen therethrough, which may be referred to as a transparent display. A representative example of this transparent display may include a transparent organic light emitting diode (TOLED), etc. The mobile terminal 100 may include two or more display units 151. For example, the mobile terminal may include both an external display unit (not shown) and an internal display unit (not shown). The touch screen may be configured to detect a touch input pressure as well as a touch input location and a touch input area.
The display unit 151 may be implemented in two or more in number according to a configured aspect of the mobile terminal 100. For instance, a plurality of displays may be arranged on one surface integrally or separately, or may be arranged on different surfaces.
Here, if the display unit 151 and a touch sensitive sensor (referred to as a touch sensor) have a layered structure therebetween, the structure may be referred to as a touch screen. The display unit 151 may be used as an input device rather than an output device. The touch sensor may be implemented as a touch film, a touch sheet, a touch pad, and the like.
The touch sensor may be configured to convert changes of a pressure applied to a specific part of the display unit 151, or a capacitance occurring from a specific part of the display unit 151, into electric input signals. Also, the touch sensor may be configured to sense not only a touched position and a touched area, but also a touch pressure.
When touch inputs are sensed by the touch sensors, corresponding signals are transmitted to a touch controller (not shown). The touch controller processes the received signals, and then transmits corresponding data to the controller 180. Accordingly, the controller 180 may sense which region of the display unit 151 has been touched.
Referring to
The proximity sensor may include 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 so on. When the touch screen is implemented as a capacitance type, proximity of a pointer to the touch screen is sensed by changes of an electromagnetic field. In this case, the touch screen (touch sensor) may be categorized into a proximity sensor.
In the following description, for the sake of brevity, recognition of the pointer positioned to be close to the touch screen without being contacted will be called a ‘proximity touch’, while recognition of actual contacting of the pointer on the touch screen will be called a ‘contact touch’. In this case, when the pointer is in the state of the proximity touch, it means that the pointer is positioned to correspond vertically to the touch screen.
The proximity sensor detects a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch speed, a proximity touch time, a proximity touch position, a proximity touch movement state, or the like), and information corresponding to the detected proximity touch operation and the proximity touch pattern can be outputted to the touch screen.
The audio output module 152 may output audio data received from the wireless communication unit 110 or stored in the memory 160 in a call signal reception mode, a call mode, a record mode, a voice recognition mode, a broadcast reception mode, and the like. Also, the audio output module 152 may provide audible outputs related to a particular function (e.g., a call signal reception sound, a message reception sound, etc.) performed in the mobile terminal 100. The audio output module 152 may include a receiver, a speaker, a buzzer, etc.
The alarm unit 153 outputs a signal for informing about an occurrence of an event of the mobile terminal 100. Events generated in the mobile terminal may include call signal reception, message reception, key signal inputs, and the like. In addition to video or audio signals, the alarm unit 153 may output signals in a different manner, for example, to inform about an occurrence of an event. For example, the alarm unit 153 may output a signal in the form of vibration. Such video signal or audio signal may be output through the display unit 151 or the audio output module 152. Accordingly, the display unit 151 or the audio output module 152 may be categorized into part of the alarm unit 153.
The haptic module 154 generates various tactile effects the user may feel. A typical example of the tactile effects generated by the haptic module 154 is vibration. The strength and pattern of the haptic module 154 can be controlled. For example, different vibrations may be combined to be outputted or sequentially outputted.
Besides vibration, the haptic module 154 may generate various other tactile effects such as an effect by stimulation such as a pin arrangement vertically moving with respect to a contact skin, a spray force or suction force of air through a jet orifice or a suction opening, a contact on the skin, a contact of an electrode, electrostatic force, etc., an effect by reproducing the sense of cold and warmth using an element that can absorb or generate heat.
The haptic module 154 may be implemented to allow the user to feel a tactile effect through a muscle sensation such as fingers or arm of the user, as well as transferring the tactile effect through a direct contact. Two or more haptic modules 154 may be provided according to the configuration of the mobile terminal 100.
The memory 160 may store software programs used for the processing and controlling operations performed by the controller 180, or may temporarily store data (e.g., a map data, phonebook, messages, still images, video, etc.) that are inputted or outputted. The memory 160 may store therein data on vibrations and sounds of various patterns output when a touch is input onto the touch screen.
The memory 160 may include at least one type of storage medium including a Flash memory, a hard 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, and an optical disk. Also, the mobile terminal 100 may be operated in relation to a web storage device that performs the storage function of the memory 160 over the Internet.
The interface unit 170 serves as an interface with every external device connected with the mobile terminal 100. For example, the external devices may transmit data to an external device, receives and transmits power to each element of the mobile terminal 100, or transmits internal data of the mobile terminal 100 to an external device. For example, the interface unit 170 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.
Here, the identification module may be a chip that stores various information for authenticating the 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 (referred to as ‘identifying device’, hereinafter) may take the form of a smart card. Accordingly, the identifying device may be connected with the terminal 100 via a port.
When the mobile terminal 100 is connected with an external cradle, the interface unit 170 may serve as a passage to allow power from the cradle to be supplied therethrough to the mobile terminal 100 or may serve as a passage to allow various command signals inputted by the user from the cradle to be transferred to the mobile terminal therethrough. Various command signals or power inputted from the cradle may operate as signals for recognizing that the mobile terminal is properly mounted on the cradle.
The controller 180 typically controls the general operations of the mobile terminal. For example, the controller 180 performs controlling and processing associated with voice calls, data communications, video calls, and the like. The controller 180 may include a multimedia module 181 for reproducing multimedia data. The multimedia module 181 may be configured within the controller 180 or may be configured to be separated from the controller 180.
The controller 180 may perform a pattern recognition processing to recognize a handwriting input or a picture drawing input performed on the touch screen as characters or images, respectively.
Once a preset condition of the mobile terminal is satisfied, the controlled 180 can execute a locked state for limiting a user's input of control commands with respect to applications. And, the controller 180 can control a locked screen displayed in the locked state, based on a touch input sensed by the display unit (hereinafter, will be referred to as ‘touch screen’ 151) in the locked state.
The power supply unit 190 receives external power or internal power and supplies appropriate power required for operating respective elements and components under the control of the controller 180.

Hereinafter, a structure of the mobile terminal of
The mobile terminal 100 according to the present disclosure is a bar type mobile terminal. However, the present disclosure is not limited to this, but may be applied to a slide type in which two or more bodies are coupled to each other so as to perform a relative motion, a folder type, or a swing type, a swivel type and the like.
A body of the mobile terminal 100 has a front surface, side surfaces and a rear surface. The body has two ends in a lengthwise direction.
A case (casing, housing, cover, etc.) forming an outer appearance of the body may include a front case 101 and a rear case 102. A space formed by the front case 101 and the rear case 102 may accommodate various components therein. At least one intermediate case may further be disposed between the front case 101 and the rear case 102.
Such cases may be formed by injection-molded synthetic resin, or may be formed using a metallic material such as stainless steel (STS) or titanium (Ti).
At the front case 101, may be disposed a display unit 151, an audio output unit (or an audio output module) 152, a camera 121, user input units 130/131 and 132, a microphone 122, an interface unit 170, etc.
The display unit 151 occupies most parts of a main surface of the front case 101. The audio output unit 152 and the camera 121 are arranged at a region adjacent to one end of the stereoscopic display unit 151, and the user input unit 131 and the microphone 122 are arranged at a region adjacent to another end of the display unit 152. The user input unit 131, the interface unit 170, etc. may be arranged on side surfaces of the front case 101 and the rear case 102. On the other hand, the microphone 122 is arranged at another end of the body.
The user input unit 130 is manipulated to receive a command for controlling the operation of the mobile terminal 100, and may include a plurality of manipulation units 131 and 132. The manipulation units may be referred to as manipulating portions, and may include any type of ones that can be manipulated in a user's tactile manner.
Commands inputted through the first or second user input units 131 and 132 may be variously set. For instance, the first manipulation 131 is configured to input commands such as START, END, SCROLL or the like, and the second manipulation unit 132 is configured to input commands for controlling a level of sound outputted from the audio output unit 152, or commands for converting the current mode of the display unit 151 to a touch recognition mode.
Referring to
A power supply unit 190 for supplying power to the mobile terminal 100 is mounted to the body. The power supply unit 190 may be mounted in the body, or may be detachably mounted to the body.
A touch pad 135 for sensing touch may be additionally mounted to the rear case 102. Like the display unit 151, the touch pad 135 may be formed to be light-transmissive. In this case, if the display unit 151 is configured to output visual information from two surfaces thereof, the visual information can be recognized through the touch pad 135. The information output from the two surfaces can be controlled by the touch pad 135. Alternatively, a display may be additionally mounted to the touch pad 135, so that a touch screen can be disposed at the rear case 102.
A camera 121′ may be additionally provided on the rear case 102. The camera 121′ faces a direction which is opposite to a direction faced by the camera 121 (refer to
For example, the camera 121 may operate with relatively lower pixels (lower resolution). Thus, the camera 121 may be useful when a user can capture his face and send it to another party during a video call or the like. On the other hand, the camera 121′ may operate with a relatively higher pixels (higher resolution) such that it can be useful for a user to obtain higher quality pictures for later use. The cameras 121 and 121′ may be installed at the body so as to rotate or pop-up.
A flash 123 and a mirror 124 may be additionally disposed close to the camera 121′. The flash 123 operates in conjunction with the camera 121′ when taking a picture using the camera 121′. The mirror 124 can cooperate with the camera 121′ to allow a user to photograph himself in a self-portrait mode.
An audio output unit 252′ may be additionally arranged on a rear surface of the body. The audio output unit 252′ (refer to
A power supply unit 190 for supplying power to the mobile terminal 100 is mounted to the body. The power supply unit 190 may be mounted in the body, or may be detachably mounted to the body.
The touch pad 135 operates in association with the display unit 151 of the front case 101. The touch pad 135 may be disposed on the rear surface of the display unit 151 in parallel. The touch pad 135 may have a size equal to or smaller than that of the display unit 151.
The controller 180 of the mobile terminal according to the exemplary embodiment, which can include at least one component described above, may perform a locked state for limiting the input of a command control for an application. A locked screen may be output in the locked state, and screen information output on the display unit before the performance of the locked state may be set as the locked screen, based on a user's selection. That is, the screen information output on the display unit before the performance of the locked state may be output as the locked screen in the locked state on the display unit.
An image objective for changing the locked state into a released state may be output on the locked screen.
That is, in a case where the display unit 151 is in an on-state in the locked state, the image objective may be output together with the screen information set as the locked screen on the display unit 151.
The controller 180 releases the locked state in response to a touch gesture for the image objective, and changes the state of the mobile terminal from the locked state into the released state.
Here, the locked state is a state in which the user's input of control commands to applications included in the mobile terminal is limited. The locked state is used to prevent functions and applications of a mobile terminal having a touch screen (or display unit 151 configured with a touch screen) from being activated or non-activated by the user's unintentional input of a control command in the mobile terminal. Thus, in the locked state, the user's input a control command input through the touch screen (or display unit 151) or the user input unit 130 can be limited within a set range.
Meanwhile, although the user's input of the control command is limited in the locked state, the functions and applications of the mobile terminal, which have been operated before the performance of the locked state, may be continuously executed.
The released state is a state in which the user's input of control commands to the mobile terminal is not limited. Thus, in the released state, the functions and applications of the mobile terminal are activated or non-activated depending on a control command input by a user through the touch screen (or display unit 151) or the user input unit 130.
Here, the locked state may be performed when the user's input is not sensed by the touch screen (or display unit 151) or the user input unit 130 provided in the mobile terminal for a predetermined time. The predetermined time may be changed depending on the user's setting.
The locked state may be performed when the user presses a special key (e.g., a hold key) provided to the mobile terminal. Here, the special key is previously set to perform the locked state.
As described above, the case where the user's input to the mobile terminal is not sensed for the predetermined time or the case where the user's input for the special key is sensed to perform the locked state can be expressed as ‘the locked state is performed when the set condition is satisfied.’
The released state may be performed by the special key again pressed by the user in the locked state or the touch gesture input to the image objective displayed in the locked state.
Meanwhile, the lock screen image (or screen information) displayed on a locked screen in the conventional mobile terminal may be generally a specific image set by a user or controller. Here, the specific image may be a static or dynamic image. Therefore, in a case where a locked state is performed, the same specific image is always output on the locked screen. However, in a case where the locked state is performed while the user executes a specific function through the mobile terminal, the user desires to continuously receive screen information corresponding to the specific function.
Accordingly, in the mobile terminal according to the present disclosure, when a specific function, e.g., a specific application is executed on a screen of the mobile terminal, the execution screen or specific image of the application can be set as a locked screen, based on a user's selection. In a case where the locked state is performed, the set execution screen or specific image can be output on the display unit.
Hereinafter, a method for setting a locked screen will be described in detail with reference to
First, in the control method according to the exemplary embodiment, screen information is displayed on the display unit 151 (S310).
Here, the screen information may be any one of an execution screen of any one of a plurality of applications, a screen of home screen page and a menu screen. The screen information is output on the display unit 151 in a state in which the mobile terminal is activated, i.e., in a state in which the locked state is not performed.
Meanwhile, the controller 180 may receive a control signal for setting the screen information as a locked screen while the screen information is output on the display unit 151 (S320).
The control signal may be received through various channels. For example, the control signal may be received when a user selects an image objective corresponding to the function of setting the locked screen. Referring to
The item “Set as locked screen,” as shown in
Meanwhile, in a case where the locked state is performed after the control signal for setting the execution screen 200 as the locked screen is received as described above, the controller 180 controls the display unit 151 so that the execution screen 200 (or screen information) is output on the display unit 151, based on the received control signal (S330).
That is, in the locked state, the controller 180, as shown in
As such, screen information (or execution screen) arbitrarily set by the user may be output as the locked screen on the display unit 151, rather than a lock screen image (or moving image) previously set to be output in the locked state.
Meanwhile, in a case where specific screen information is set by the user rather than the previously set lock screen image as described above, the controller 180 may temporarily output the screen information in the locked state and then control the display unit 151 so that the previously set lock screen image is output on the display unit 151.
For example, if the locked state is converted into a released state, based on a user's setting while an execution screen 310a of a map application is output as the locked screen as shown in
Meanwhile, the controller 180 according to the exemplary embodiment may receive a screen to be output in the locked state, selected by the user, using another method in addition to the method described above. For example, as shown in
For example, in a case where the touch input for the second graphic objective 420 corresponds to the release condition as shown in
In a case where the touch input for the first graphic objective 410 corresponds to the release condition as shown in
In the mobile terminal according to the exemplary embodiment, the controller 180 converts the locked state into the released state and immediately outputs a screen desired by the user, so that it is possible to an inconvenience that the user should reselect an application to be executed in the released state.
Meanwhile, in the mobile terminal according to the exemplary embodiment, the controller 180 may output the screen information on the locked screen when the screen information corresponds to a predetermined condition, in addition to the method for immediately outputting the screen information on the locked screen in the locked state performed after the control signal for setting the screen information to be displayed on the locked screen is received.
Here, the predetermined condition may be set based on a user's selection. The predetermined condition may be a condition related to ambient environment or state information of the mobile terminal, such as time, weather, position, place or battery capacity of the mobile terminal.
For example, in a case where the predetermined condition is set to “Near destination” by the user while the execution screen 200 of the map application is set as the locked screen as shown in
In this case, the controller 180 may monitor the position of the mobile terminal at a predetermined interval, and may receive, from the user, detailed information related to how far distant from the destination the execution screen is to be output, etc.
As such, in the mobile terminal according to the exemplary embodiment, the controller 180 may output the screen information (or execution screen of the application) set by the user on the locked screen at the time desired by the user.
As described above, in a case where the screen information (or execution screen) selected by the user is set as the locked screen, the controller 180 may temporarily output the screen information on the display unit 151, rather than the previously set lock screen image.
Only when the screen information set by the user satisfies a state of the mobile terminal or when the ambient environment satisfies a specific condition, the controller 180 may control the display unit 151 so that the screen information is output on the display unit 151 in the locked state.
As described above, in the mobile terminal according to the exemplary embodiment, the screen information selected by the user can be arbitrarily set as the locked screen, rather than the previously set lock screen image. Thus, the user can continuously receive the screen information even when the locked state for limiting a control command for an application is performed.
Hereinafter, a method for receiving a control signal for setting screen information on the display unit as a locked screen will be described in detail with reference to
As an example, in the mobile terminal according to the exemplary embodiment, the controller 180, as described in
As another example, in a case where a control signal for capturing screen information 200 output on the display unit 151 is received in the released state, the controller 180, as shown in
The control signal the control signal for capturing the screen information 200 may be received, based on at least a touch input to the display unit 151 or a hot key provided to the mobile terminal.
Meanwhile, in addition to the method for outputting the captured screen information 200 in an image form on the locked screen 300, the controller 180, based on the control signal as shown in
As another example, in a case where a control signal for controlling the mobile terminal is not received from the user for a reference time as shown in
That is, in a case where the control signal for controlling the screen information is not received from the user for the reference time, the controller 180 may perform the locked state and receive a control signal for setting the screen information as the locked screen, based on performance of the locked state. The control signal may be received only when the screen information is an execution screen of an application. Particularly, the control signal may be received only when the screen information is an execution screen of a predetermined kind of application.
Here, the predetermined kind of application may be set according to a user's selection, or may be set according to characteristics of the application.
Meanwhile, the reference time is a time set so that the locked state is performed when a control command is not received for a predetermined time in the mobile terminal. The degree of the reference time may be variously set according to the user's setting.
That is, although the locked state is performed differently from the user's intention, the screen information output on the display unit before the locked state is performed is set as the locked screen, so that the user can continuously receive necessary information even in the locked state.
As described above, in the mobile terminal according to the exemplary embodiment, it is possible to set the screen information output on the display unit as the locked screen, based on the control signal received through various channels.
Hereinafter, a method for changing a locked screen will be described in detail with reference to the accompanying drawings.

As described above, in the mobile terminal according to the exemplary embodiment, the controller 180 may control the display unit 151 so that an execution screen of an application is output on the locked screen 300, based on a user's selection. In this case, the controller 180 may output the execution screen output on the display unit 151 at the time when a control signal for setting the locked screen is received in an image form on the locked screen. However, in addition to the image form, the controller 180 may control the display unit 151 so that the execution screen of the application itself is output on the locked screen. That is, information on a progressive state of the application or update information related to the application may be displayed on the locked screen.
As an example, in a case where an execution screen of an application related to position information with which a user can identify the position of the mobile terminal is set as the locked screen 300 as shown in
As another example, in a case where an execution screen of an application related to a social network service is set as the locked screen 300 as shown in
As described above, the controller 180 can update the execution screen of the application displayed on the locked screen 300 so that the user can receive update information on the application.
Hereinafter, a method for controlling an application corresponding to screen information on a locked screen in a locked state will be described in detail with reference to the accompanying drawings.
Generally, the input of a control command for an application is limited by limiting a touch input applied on the display unit 151 in the locked state. However, in the mobile terminal according to the exemplary embodiment, a control command for controlling an application corresponding to screen information display on the locked screen may be received through a touch input.
