The live zoom execution screen may include at least one of a zoom image 800, a magnification adjustment bar 810, an original image PIP 820, an additional function menu 830, and a guide window 840.

The zoom image 800 refers to an image enlarged by the live zoom function. The zoom image 800 is an image in which part of the original image is enlarged and is displayed on the entire screen. The control unit 170 displays the zoom image 800 on the entire screen of the display unit 180.

The control unit 170 can change the zoom image 800 through the direction key buttons provided on the remote control device 200. When the control unit 170 receives a direction key input signal provided in the remote control device 200, it changes the enlarged area in a direction corresponding to the input direction key and displays the zoom image 800.

If the remote control device 200 is a motion recognition remote control, the control unit 170 can change the zoom image 800 through the pointer 205. Specifically, the control unit 170 may receive a command to select a point of the zoom image 800 through the pointer 205. The control unit 170 may change the zoom image 800 so that the selected point is located at the center of the screen. That is, the control unit 170 can change and display the enlarged area in the original image so that the selected point is located in the center of the screen.

Users can conveniently change the magnification position through this method. Therefore, the user can easily view the part he or she wants to enlarge by selecting it.

The magnification control bar 810 is a bar for adjusting the magnification of the zoom image 800.

The control unit 170 can change the magnification ratio through the (-) button and (+) button provided on the remote control device 200. Specifically, the control unit 170 can lower the magnification ratio when receiving a command to select the (-) button, and increase the magnification ratio when receiving a command to select the (+) button.

If the remote control device 200 is a gesture recognition remote control, the control unit 170 can adjust the magnification through a wheel. Additionally, if the remote control device 200 is a gesture recognition remote control, the control unit 170 may adjust the magnification through the pointer 205. Specifically, the control unit 170 can change the magnification ratio as it receives commands to select the (-) icon and (+) icon displayed on the screen.

When changing the magnification ratio, the control unit 170 may display the changed magnification ratio.

The original image PIP 820 is a mini-view image representing the original image corresponding to the zoom image 800. The original image PIP 820 includes the original image and a guide box indicating the enlarged area. The guide box indicates which area of the original image the enlarged image is. Accordingly, the control unit 170 can reduce the size of the guide box as the magnification increases and increase the size of the guide box as the magnification decreases. The user can see which area has been enlarged through the original image PIP (820).

Additionally, the user can change the enlarged area through the original image PIP (820). The control unit 170 may receive a command to select a point of the original image PIP 820 through the pointer 205. The control unit 170 may change and display the zoom image 800 so that the area corresponding to the selected point is located at the center of the screen.

The additional function menu 830 includes at least one icon that executes additional functions available in connection with Live Zoom. Additional functions that can be provided in relation to Live Zoom include at least one of the following: live zoom recording, time shift, pause/play, capture, and menu hide. It can be included. A detailed description of each icon and its corresponding function will be provided later.

The guide window 840 is a window that explains operating methods related to the live zoom function. The control unit 170 may display an explanatory message according to the current live zoom operation status or the position of the pointer 205 on the guide window 840. Users can easily use live zoom through the guide window 840.

Figure 5 will be described again.

The display device 100 may display a live zoom execution screen according to a live zoom execution request signal. At this time, the control unit 170 may display the Live Zoom execution screen differently depending on the state of the display device 100. In particular, the control unit 170 may display the additional function menu 830 differently depending on the state of the display device 100. The state of the display device 100 may include the type of input signal, the connection state with the remote control device 200, etc.

Accordingly, the control unit 170 may determine the state of the display device 100 to display the live zoom execution screen.

The control unit 170 may determine the transmission location of the input signal corresponding to the displayed image (S103).

Specifically, the control unit 170 may determine whether the input signal corresponding to the displayed image was received from among the storage unit 140, USB, broadcast receiver 130, and HDMI.

This is because the additional functions that the display device 100 can provide vary depending on the input signal of the display image. The control unit 170 has the effect of preventing user misunderstanding or confusion by displaying or not displaying additional function icons depending on the additional functions that can be provided. The method of displaying the additional function menu is explained in detail below.

The control unit 170 can determine the location where the input signal of the displayed image was transmitted and obtain whether the input signal was received through the storage unit 140 or USB (S105).

This is because the control unit 170 can provide a zoom recording function in relation to live zoom when displaying an input signal received through the storage unit 140 or USB on the display unit 180.

Zoom recording refers to a function that saves the change history when using Live Zoom to change the magnification factor and magnification area in relation to one original video. The display device 100 can apply the original image and the change history according to zoom recording together to automatically display the image with the magnification and magnification area changed the same as before.

Even if it is the same video, the part that each person wants to enlarge and view may be different. For example, a user may want to zoom in on only a specific member in a video of a singer's performance, zoom in on only a child in a video at a school performance, or zoom in on a scene where a goal is scored in a soccer game. Therefore, when using live zoom to enlarge a video, the display device 100 can create your own video by storing changes in the magnification factor and enlargement area.

According to Zoom recording, multiple versions of video can be created in relation to one video. When using the zoom recording function, it has the effect of reducing the inconvenience of having to repeat the same live zoom every time you view the same video.

However, the display device 100 must be paired with a gesture recognition remote control to support the zoom recording function.

The control unit 170 can obtain whether it is paired with a gesture recognition remote control (S107).

Pairing is the process of registering two or more electronic devices so that they can be connected and operated. After pairing only once, it will connect automatically from then on.

The display device 100 may determine whether it is paired with a remote control device 200 capable of motion recognition. This is because the display device 100 can support the zoom recording function by displaying the pointer 205 on the display unit 180 as it detects the movement of the remote control device 200. Accordingly, the display device 100 can support the zoom recording function when it is paired with a gesture recognition remote control and displays the pointer 205 on the screen.

Accordingly, the control unit 170 can obtain whether the pointer 205 is displayed on the screen when paired with a gesture recognition remote control (S109).

The control unit 170 can control the display unit 180 to display the pointer 205 when paired with a gesture recognition remote control. Additionally, the control unit 170 can control the pointer 205 not to be displayed if no movement of the motion-recognition remote control is detected even when paired with a motion-recognition remote control. For example, the control unit 170 may not display the pointer 205 if the initial movement of the gesture recognition remote control is not detected after turning on the display device 100. Alternatively, the control unit 170 may control the pointer 205 to be removed if no movement of the motion recognition remote control is detected for more than a preset time while the pointer 205 is being displayed.

In this way, the control unit 170 can control to display or not display the pointer 205 on the screen even if it is paired with a gesture recognition remote control.

If the control unit 170 is paired with a motion recognition remote control (S107) and the pointer 205 is displayed on the screen (S109), an additional function menu including an activated zoom recording icon can be obtained (S111).

The control unit 170 is paired with a motion recognition remote control and can support the zoom recording function when the pointer 205 is displayed on the screen. Accordingly, the control unit 170 may indicate that the zoom recording function is supported by displaying a zoom recording icon. In particular, the control unit 170 can execute zoom recording by displaying an activated zoom recording icon.

Next, Figure 9 is a diagram for explaining an activated zoom recording icon according to an embodiment of the present invention.

The control unit 170 may control the zoom recording icon 831 to be displayed when the pointer 205 is displayed while displaying an image received through the storage unit 140 or USB. In particular, the zoom recording icon 831 may be activated.

The zoom recording icon 831 is an icon for saving changes in the magnification ratio or magnification area of the image. When the control unit 170 receives a command to select a zoom recording icon, it can control the change to be saved when the magnification ratio or magnification area of the image is changed.

An activated icon may mean an icon that executes a function corresponding to the icon when the control unit 170 receives a command to select the icon. Conversely, a deactivated icon may mean an icon that does not execute a function corresponding to the icon even if the control unit 170 receives a command to select the icon.

The control unit 170 may obtain an additional function menu 830 including an activated zoom recording icon 831. The additional function menu 830 may include a stop icon 832, a capture icon 833, and a menu hide icon 834 in addition to the activated zoom recording icon 831. A detailed explanation of each icon will be provided later.

Figure 5 will be described again.

If the control unit 170 is paired with a motion recognition remote control (S107), but the pointer 205 is not displayed on the screen (S109), an additional function menu including a deactivated zoom recording icon can be obtained (S113).

The control unit 170 can support the zoom recording function when paired with a motion recognition remote control. However, the control unit 170 cannot execute the zoom recording function if the pointer 205 is not displayed on the screen even if it is paired with a gesture recognition remote control. Accordingly, the control unit 170 can control the display of a deactivated zoom recording icon to indicate a state in which the zoom recording function can be provided but is currently not executable.

Next, Figure 10 is a diagram for explaining a deactivated zoom recording icon according to the first embodiment of the present invention.

The control unit 170 displays images received through the storage unit 140 or USB and is paired with a motion recognition remote control, so it may be able to provide a zoom recording function. However, if the pointer 205 is not present, the zoom recording function cannot be performed. You can judge. Accordingly, as shown in FIG. 10, the control unit 170 can obtain and control an additional function menu 830 including a deactivated zoom recording icon 831 to be displayed. The additional function menu 830 may include a stop icon 832, a capture icon 833, and a menu hide icon 834 in addition to the deactivated zoom recording icon 831. The stop icon 832, capture icon 833, and menu hide icon 834 may be activated icons.

The control unit 170 may not perform any operation when receiving a command to select a deactivated zoom recording icon 831.

Additionally, the control unit 170 may display the non-activated zoom recording icon 831 to distinguish it from other activated icons. For example, the control unit 170 may display activated icons and deactivated icons with different opacity.

Through this, the user can see at a glance that the zoom recording function cannot currently be performed. In other words, it has the effect of providing a way for the user to clearly know whether zoom recording can be performed or not by looking at the currently displayed icon.

Next, Figure 11 is a diagram for explaining a deactivated zoom recording icon according to a second embodiment of the present invention.

The controller 170 may control the display of the non-activated zoom recording icon 831 and further display the non-activated explanation window 1100, similar to FIG. 10 . The deactivation explanation window 1100 is intended to indicate the reason why the icon is deactivated or how to activate the icon. In the example of FIG. 11 , the control unit 170 displays a deactivation explanation window 1100 including the message “Available through gesture recognition remote control” along with a deactivated zoom recording icon 831.

The user can easily obtain a method of executing a deactivated icon through the deactivation explanation window 1100.

Figure 5 will be described again.

The control unit 170 receives an input signal through the storage unit 140 or USB (S105), but if it is not paired with a motion recognition remote control, the additional function menu 830 excluding the zoom recording icon and time shift icon cannot be obtained. There is (S115).

The control unit 170 may provide a live zoom function for an input signal received through the storage unit 140 or USB. In addition, the control unit 170 can provide a zoom recording function when paired with a gesture recognition remote control. Therefore, even if the control unit 170 receives an input signal through the storage unit 140 or USB, if it is not paired with a gesture recognition remote control, it can only provide the live zoom function and cannot provide the zoom recording function. Therefore, in this case, the control unit 170 can control the zoom recording icon 831 not to be displayed on the screen.

The additional function menu 830, excluding the zoom recording icon and time shift icon, will be explained later.

The control unit 170 cannot provide a zoom recording function when receiving an input signal from an external device other than the storage unit 140 or USB.

If the input signal is not received through the storage unit 140 or USB, the control unit 170 can obtain whether the image is received through the broadcast receiver 130 (S117).

The control unit 170 may provide a time shift function when the displayed image is an image received through the broadcast receiver 130.

Time shift refers to a function that allows you to arbitrarily return to the previous scene in a real-time TV broadcast. The display device 100 records real-time TV broadcasting for a certain period of time when time shifting is being performed. When the display device 100 receives a command to select a point in a recording section, it can return to that point in time and play the video. When time shifting is not performed, the display device 100 does not record real-time TV broadcasting unless there is a separate command.

When an input signal is received through the broadcast receiver 130, the control unit 170 can obtain whether time shifting is being performed (S119).

If it is determined that time shift is being performed, the control unit 170 may control the additional function menu 830 to be obtained including a time shift icon excluding the zoom recording icon.

Next, Figure 12 is a diagram for explaining a time shift icon according to an embodiment of the present invention.

As shown in FIG. 12, the control unit 170 can obtain an additional function menu 830 including a time shift icon 831, a stop icon 832, a capture icon 833, and a hide icon 834. there is. If the displayed image is an image received through the broadcast receiver 130, the control unit 170 cannot support the zoom recording function and therefore does not display the zoom recording icon.

The time shift icon 831 is an icon for displaying the time shift execution screen. That is, when the control unit 170 receives a command to select the time shift icon 831, it switches from the live zoom execution screen to the time shift execution screen. The time shift execution screen may include at least one of a progress bar indicating the broadcast recording section and the current playback section, a pause icon, and an icon returning to the live zoom execution screen. When the control unit 170 receives a command to select a return icon from the time shift execution screen to the live zoom execution screen, it can switch from the time shift execution screen to the live zoom execution screen.

When the control unit 170 receives a command to select the time shift icon 831 while enlarging an area through live zoom, it displays a time shift execution screen including the enlarged image. When the control unit 170 receives a command to change the video playback point through the progress bar, it can control the video to be played from the selected point in time according to the current magnification factor and enlargement area. In other words, the control unit 170 controls to change the playback time of the image while fixing the magnification and magnification area of the image.

Through this, the display device 100 can simultaneously provide a live zoom function and a time shift function.

Figure 5 will be described again.

If it is determined that the time shift is not being executed (S119), the control unit 170 can obtain the additional function menu 830 excluding the zoom recording icon and the time shift icon (S115).

That is, if the control unit 170 determines that time shift is not being executed, it may not display the time shift icon to display the time shift execution screen.

Next, Figure 13 is a diagram illustrating an additional function menu excluding the zoom recording icon and time shift icon according to an embodiment of the present invention.

If the zoom recording function and the time shift function are not supported, the control unit 170 may exclude the zoom recording icon and the time shift icon from the additional function menu 830. Accordingly, the control unit 170 can obtain an additional function menu 830 including a stop icon 832, a capture icon 833, and a hide icon 834, as shown in FIG. 13.

Figure 5 will be described again.

If the display image is not received through the storage unit 140, USB, or broadcast receiver 130, the control unit 170 may obtain whether the image is received through HDMI (S123).

If it is determined that the input signal has not been received through the storage unit 140, USB, broadcast receiver 130, and HDMI, the control unit 170 may determine the input signal of the displayed image again.

If it is determined that the input signal is received through HDMI, the control unit 170 can control to obtain the additional function menu 830 excluding the zoom recording icon and the time shift icon, as described with reference to FIG. 13.

The control unit 170 may display a live zoom screen including an additional function menu obtained through S111, S113, S115, or S121 (S125).

The control unit 170 obtains different additional function menus 830 depending on the input signal of the display image, pairing with a motion recognition remote control, whether the pointer 205 is displayed, and whether time shift is performed.

The control unit 170 may display a Live Zoom execution screen including the acquired additional function menu 830. The Live Zoom execution screen is as described in Figure 8. The configuration of the additional function menu 830 included in the Live Zoom execution screen may vary as described above.

In this way, the display device 100 according to an embodiment of the present invention can prevent user confusion by displaying the additional function menu 830 differently depending on the functions that can be provided and the functions that can be executed.

In addition, although it has been previously described that the control unit 170 obtains an additional function menu by determining the transmission position of an input signal corresponding to a displayed image, it can also obtain an additional function menu by determining the type of the input signal.

In FIGS. 8 to 13 , the additional function menu 830 according to an embodiment of the present invention is described as indicating the name of each function on each icon.

According to another embodiment of the present invention, the control unit 170 can control the mapping and display of different colors to each icon in the additional function menu 830.
