FIG. 6 is a flowchart showing an example of an operation method of an image display apparatus according to an embodiment of the present invention, and FIGS. 7 to 16 are drawings referred to explain the operation method of FIG.

First, referring to FIG. 6, the image display apparatus 100 receives an image through the image receiving unit 105. Then, the received image is subjected to signal processing, and the signal-processed image is displayed on the display 180.

For example, the image display apparatus 100 receives a broadcast signal received through an antenna through a tuner unit 110 and the like, processes the signal by the controller 170, Can be displayed. In particular, one broadcast signal can be processed to display one broadcast image on the display 180.

Next, the image display apparatus 100 determines whether there is a plurality of divided image display input based on a single source (S605), and if so, displays a plurality of divided images (S610).

For example, when there is an external input image display input from the set-top box through the user input interface unit 150, the control unit 170 can receive an external input image through the external device interface unit 130 have.

At this time, when there is a plurality of divided image display inputs for displaying a plurality of divided images among the external input images, the control unit 170 can receive a plurality of divided images through the external device interface unit 130. [

For example, through the set-top box 50, a plurality of divided images can be received. Specifically, the content provider, which provides the broadcast image through the set-top box 50, can transmit a plurality of divided images as one stream in order to increase the usability at the time of viewing the user, have.

The video display apparatus 100 can receive a stream having a plurality of divided images through the external device interface unit 130. [

The control unit 170 in the video display device 100 demultiplexes the received stream, extracts a plurality of divided images from the demultiplexed signal, and performs signal processing on each of the divided images, It can be controlled to be displayed on the display 180 as one screen. Accordingly, the user can view a plurality of divided images at the same time, thereby making it possible to increase the usability of the user.

Meanwhile, the image display apparatus 100 displays an indicator for selecting or focusing any one of the plurality of divided images (S615).

For example, in a state where a plurality of divided images are displayed, when there is an operation such as a menu key of the remote controller 200, the controller 170 generates an indicator for selecting or focusing any one of the plurality of divided images , And display on the display 180 an indicator generated in any one of the plurality of divided images.

For example, when four divided images are displayed on the display 180, one of them may be displayed with an indicator that thickens the frame of the image.

 On the other hand, the image display apparatus 100 determines whether there is an indicator movement input (S625), and if so, moves the indicator and displays it (S625).

The control unit 170 may control the indicator to move and display according to the movement input to the indicator. For example, if there is a direction key movement input of the remote control device 200, the indicator can be moved in the corresponding direction. Specifically, in accordance with the left key movement input, the indicator can be shifted to be located in the left divided image.

On the other hand, the control unit 170 can control to display the pointer displayed in accordance with the motion of the remote control device as shown in Fig. 4. In a state in which a plurality of divided images are displayed, It is possible to control to select or focus any one of the divided images. For example, an indicator may be displayed on a segmented image where the pointer is located, and an indicator may be moved between a plurality of segmented images as the pointer moves.

Next, the image display apparatus 100 determines whether there is an image setting input for the divided image in which the indicator is located (S630), and if so, displays the image setting object (S635). Then, the image display apparatus 100 controls to apply the same image setting to a plurality of divided images in accordance with the set values set in the setting object (S640).

When there is an image setting input, the control unit 170 can control to display the image setting object for image setting for the divided image in which the indicator is located.

The image setting object may include at least one of image sharpness, motion compensation, color temperature, color saturation, brightness, contrast, motion vector, and frame rate.

Meanwhile, the external device interface unit 130 may further receive divided image related information including genre information for the divided image, in addition to the divided images in the stream.

If there is an image setting input in a state in which one of the plurality of divided images is selected or focused, the control unit 170 sets the optimum setting value, the maximum setting value, and the maximum setting value corresponding to the genre of the corresponding divided image, It is possible to control to provide any one of the recent setting values as the default setting values in the video setting object. Accordingly, the user can easily set various setting values during image setting.

On the other hand, when setting various image setting values in the image setting object by user input, the control unit 170 not only performs the image signal processing according to the set values for the corresponding divided images, Also for the divided image, the image signal processing according to the set value is performed.

Then, the control unit 170 controls the display 180 to display a plurality of divided images based on the same set values for all of the plurality of divided images. Thus, it is possible to easily apply image settings to a plurality of divided images.

According to this method, since the image is set around the divided image which the user is most interested in, it is possible to provide the image based on the setting suitable for the user's taste.

The divided image related information received by the external device interface unit 130 includes information indicating whether or not the stream includes a plurality of divided images in addition to the genre information of the divided images, And may further include information. The control unit 170 can control to display a plurality of divided images in the order according to the index information when displaying the plurality of divided images based on the index information for each of the plurality of divided images.

Meanwhile, the divided image related information received by the external device interface unit 130 may further include area size information or area location information for each of the plurality of divided images. The controller 170 extracts the size information or the area position information and determines the size or position of the plurality of divided images when displaying the plurality of divided images based on the extracted size information or the area position information.

On the other hand, if there is not a plurality of divided image display input in operation S605, a single image is displayed (S607). For example, one broadcast image that has been displayed can be continuously displayed.

The operation method of FIG. 6 will be described in more detail with reference to FIG. 7 and subsequent figures.
