However, in the present embodiment, in the process of controlling the video playback speed according to the proximity signal, when a touch signal through the display unit 151 is input (S265), the controller 180 pauses the video playback, the touch A predetermined number of frame screens are displayed on the display unit 151 before and after the displayed screen (S275). In this case, the number of frame screens displayed on the display unit 151 may be selected by a user command, and the predetermined number of frame screens may be displayed as thumbnail-shaped images.

If any one of the frame screens displayed on the display unit 151 is selected by a touch input, the controller 180 captures the selected screen (S290). A captured image is generated by screen capture, and the generated captured image is stored in a setting area of the memory 160 under a file name assigned by the controller 180. In this case, a message indicating that the captured image is generated and stored may be displayed.

If a different screen is selected from the frame screens displayed on the display unit 151 (S295), the controller 180 repeatedly performs a process of turning on the selected screen (S290). If no other screen is selected among the frame screens displayed on the display unit 151 or if the screen capture end is selected (S285), the controller 180 continues the process of displaying the video screen by playing the video ( S250).

By such a process, a screen desired by the user can be captured among the touched screen and the front and rear frame screens.

6A and 6B are flowcharts provided to explain a method for controlling a portable terminal according to a third embodiment of the present invention. Also in the present embodiment, the process of steps S300 to S320 for playing the selected video file to display the video screen and controlling the video playback speed according to the detected proximity signal until the end of video playback is selected, the above-described embodiment Same as described in

However, in the process of controlling the video playback speed according to the proximity signal, if a touch signal through the display unit 151 is input (S315), the controller 180 captures the touched screen, generates a captured image, and generates The captured image is displayed on the display unit 151 in full screen (S325). The captured image may be stored with a preset file name in a preset area, and may be configured to display a menu for allowing a user to select a file name and a storage area of the captured image. When storing the captured image, capture related information is stored together.

The controller 180 may have a first direction in which a touch and drag signal in left and right directions, or a user's finger lightly draws the surface of the touch screen in a left and right direction has a directionality such as a touch flick signal in a left and right direction. When the touch signal is input (S330), the captured image is set as the current frame screen according to the direction indicated by the touch signal, and the previous frame screen or the next frame screen is displayed on the display unit 151 (S335). For example, when a touch signal having a left direction is input, the frame screen before the current frame may be displayed, and when a touch signal having a right direction is input, the next frame screen may be displayed. In this case, the frame screen may be displayed immediately before or after the current frame, but the screen may be displayed a few frames before or a few frames after the setting.

When the touch signal through the display unit 151 is input again while the previous frame screen or the next frame screen of the captured image is displayed, the controller 180 captures the touched frame screen to capture the captured image. It generates (S345).

When the captured image is touched again, the controller 180 inverts the captured image and controls the captured image to be displayed with the capture related information on the back side (S360). The capture related information may include a file size, a creation date, a captured video and related information of the selected captured image.

If the back side of the captured image is touched again or a predetermined time elapses without a touch input, the controller 180 controls to display the original captured image before flipping, and returns to step S330 (S370). If the captured image is not touched in step S350 and the screen capture end is selected (S355), the process returns to step S300 and the controller 180 continues the process of displaying the video screen by playing the video.

By such a process, a desired screen can be captured from frame frames before and after the touched screen to generate a captured image. In addition, although the left and right directions are described as the first direction in this embodiment, the direction of the touch signal capable of displaying the frame screens before and after the touched screen may be arbitrarily set according to a user command.

7A and 7B are flowcharts provided to explain a method for controlling a mobile terminal according to a fourth embodiment of the present invention. Also in this embodiment, the processes of steps S400 to S420 for displaying the moving picture screen and controlling the moving picture reproduction speed according to the detected proximity signal until the end of moving picture reproduction is selected are the same as those described in the above-described embodiment.

However, in the process of controlling the video playback speed according to the proximity signal, when a touch signal through the display unit 151 is input, the controller 180 controls the still picture to be displayed by stopping the playback of the video (S425). .

When a touch signal in a first direction such as an up and down direction is input, after capturing a screen to generate a captured image (S435), a menu for selecting whether to move to the captured image storage folder is displayed (S440). If the move to the storage folder is selected, the controller 180 moves to the preset storage folder and controls the selected operation to be performed (S460). Thereafter, if the end of the video playback is selected, the process ends, otherwise, the video playback is continued again (S465).

In step S440, when moving to the storage folder is not selected, the displayed menu is controlled to disappear, and when a touch signal in a second direction such as a left and right direction different from the first direction is input, the frame before or after the still image. The screen is controlled to be displayed (S450). If the screen is not turned off and the end is not selected, the controller 180 allows the subsequent process to be executed again in step S430.

8A and 8B are flowcharts provided to explain a method for controlling a mobile terminal according to a fifth embodiment of the present invention. Also in the present embodiment, the process of steps S500 to S520 to play the selected video file to display the video screen, and control the video playback speed according to the detected proximity signal until the end of video playback is selected, the above-described embodiment Same as described in

However, if a touch signal is input in the process of controlling the video playback speed according to the proximity signal (S515), the controller 180 pauses the video playback and displays a still picture (S525). When the touch signal in the first direction is input, the controller 180 captures a still image and generates a captured image (S535).

When the touch signal in the second direction is input, the controller 180 controls to switch to the communication mode after capturing the still image (S550). In this case, the communication mode refers to a mode capable of performing communication such as voice call, video call, message transmission, data communication, and the like. When the editing of the image is selected by turning it on in the communication mode (S555), the controller 180 provides a menu for editing the captured image to edit the captured image (S560).

The controller 180 controls the selected operation to be performed in the communication mode (S565). Examples of the operation selected in the communication mode may include turning on an image, transmitting a captured image as a background image, and sending a captured image as a background image, or transmitting the captured image as an alternate image during a video call.

 Thereafter, if the end of the video playback is selected, the process ends. Otherwise, the controller 180 continues the process of displaying the video screen by playing the video (S570).

9 is a flowchart provided to explain a method for controlling a portable terminal according to a sixth embodiment of the present invention. Referring to FIG. 9, when a video file to be played is selected by entering a video play menu such as a multimedia file play according to a user command, the controller 180 plays a selected video so that the video screen is configured as a touch screen. In order to be displayed on (S600). The controller 180 determines whether a proximity signal is detected and transmitted from the proximity sensor while displaying a video screen (S605).

The controller 180 controls the brightness of the video screen when the proximity signal detected by the user's palm or the like is transferred to the proximity sensor (S610). In this case, the proximity signal may be configured to operate when the user's finger approaches the palm of the user having a larger detection area. In addition, the brightness of the video screen may be controlled to make the screen dark enough to not identify the contents or to completely turn off the video screen. However, if the video playback is continuously performed, the controller 180 displays an indicator icon indicating that the video screen is playing (S615). The indicator icon may be displayed on the display unit 151. In addition, the indicator icon may indicate a signal indicating that the video screen is being reproduced by various methods such as an OSD (On Screen Display) message or a flashing light signal of a specific key or lamp.

When the brightness of the video screen is controlled according to the proximity signal as described above, when the touch signal through the display unit 151 is input, the controller 180 ends the video playback and displays the menu screen (S630). In this case, the displayed menu screen may be a menu displayed in an idle state, a menu related to video control, or a menu set by a user.

In addition, in the above process, once the proximity signal is detected, the brightness of the screen is darkly controlled, and then the case where the controlled screen brightness is maintained even when the proximity signal is not detected has been described. However, depending on the usage environment, the brightness of the screen may be controlled only when a proximity signal is detected, and if the proximity signal is not detected, the brightness of the screen may be controlled again.

 10 is a flowchart provided to explain a control method of the portable terminal according to the seventh embodiment of the present invention. In the present embodiment, a case where a screen is controlled according to a proximity signal when watching a broadcast will be described.

Referring to FIG. 10, a broadcast signal tuned according to a user command is received through the broadcast receiving module 111 under the control of the controller 180 (S650). The broadcast receiving module 111 demodulates the received broadcast signal to generate a transport stream, and the generated transport stream is divided into elementary streams such as video, audio, and data information, and decoded, respectively, to transport units. A broadcast signal, such as an audio and video signal and data information, can be generated in operation S665. The controller 180 displays a playable broadcast signal on the display unit 151, and displays a broadcast screen on the display unit 151 (S660).

The controller 180 checks whether a proximity signal is detected and transmitted from the proximity sensor while displaying a broadcast screen (S665). The controller 180 controls the brightness of the broadcast screen when a proximity signal is detected due to the proximity of the user's palm to the proximity sensor (S610). In this case, the brightness of the broadcast screen may be controlled to make the screen dark enough to not identify the contents or to completely turn off the video screen. The controller 180 allows the broadcast signal output from the broadcast receiving module 111 to be stored in the memory 160 (S675). In this case, the controller 180 may output a notification signal such as an indicator icon indicating that the broadcast screen is being stored.

When the brightness of the broadcast screen is controlled according to the proximity signal as described above, when a touch signal through the display unit 151 is input, a menu asking whether to watch the stored broadcast is displayed and viewing the stored broadcast is selected. In operation S690, the stored broadcast signal is reproduced. In addition, when the end of broadcast viewing is not selected, the controller 180 decodes the tuned broadcast signal and displays the broadcast screen.

In the case of a mobile terminal having a time shift function, the brightness of the screen is controlled using the time shift function, and thus the portion that is not displayed on the display unit 151 and afterwards. It is also possible to control the portion to be played back continuously.

By such a process, when the user's palm or the like is in close proximity, the brightness of the broadcast screen may be dark so that the brightness of the broadcast screen cannot be discerned or the screen may be turned off. In addition, while controlling the brightness of the broadcast screen, whether or not the sound signal is output according to the setting may be determined.

11 and 12 are views for explaining the operation of the proximity sensor. As shown in FIG. 11, when a user's finger approaches the display unit, the proximity sensor 141 installed on the first body detects this and outputs a proximity signal. In this case, when the user's finger is in the A position and in the B or C position, it may be configured to output different proximity signals. That is, the distance between the detection object approaching the proximity sensor and the output of the detection signal is generally referred to as a detection distance Sn. In this way, the proximity signal output from each proximity sensor using a plurality of proximity sensors having different detection distances is used. Comparing to it can be seen how close to the proximity object.

In addition, when a plurality of proximity sensors having different detection areas are arranged and a plurality of proximity signals are output from all of the proximity sensors, the proximity signal is output from any one of them. And a case where the user's palm, etc. of which the detection area is wider than that approaches.

Accordingly, the controller 180 may control the video playback speed to be fast or slow according to the proximity of the user's finger. If the user's finger is farther than the A position set as the threshold position, the proximity signal may not be detected, and the controller may reproduce the video at the original normal speed. In addition, when the user's palm or the like approaches, the brightness of the screen may be controlled.

12 illustrates a case in which the user's finger touches the display unit in close proximity. When the user's finger touches the display unit 151, the controller 180 determines whether there is a touch input according to a touch signal transmitted from the display unit 151 configured as a touch screen, and in which area of the display unit 151. You can tell whether it has been touched.
