[ The first image may be a broadcast moving image, a photograph, text, or the like, and the object may be the first image.

Next, the control unit 180 selects a PIP (Picture in Picture) generation menu according to a signal input from the spatial remote controller 201 (S405). By using the PIP creation menu, it is possible to display two or more images in the display area, respectively, as in the in-picture screen. The PIP generation menu may be selected through the pointing signal and the selection signal transmitted from the spatial remote controller 201 and the PIP generation menu may be selected directly by the selection signal transmitted through the user input unit 230 of the spatial remote controller 201 It is possible. The pointing signal includes a value output from the gyro sensor 241 and the acceleration sensor 243 included in the spatial remote controller 201.

Next, the controller 180 analyzes the coordinates corresponding to the inputted pointing signal in the inputted order, and determines whether the coordinates corresponding to the input pointing signal can divide the display area (S415).

If the input pointing signal is in closed curve form, the display area can be divided. In addition, whether or not the display area can be divided can be confirmed through the first coordinate and the last coordinate corresponding to the input pointing signal. At least one of the x-coordinate and the y-coordinate has a minimum value or a maximum value at the calculated first coordinate (x, y), and at least one of the x-coordinate and the y-coordinate in the last calculated coordinate (x, y) It can be determined that the display area can be divided. For example, assuming that the minimum value of the x and y coordinates is 0 and the maximum value is 100, if the calculated first coordinate is (70, 0) and the calculated last coordinate is (100, 30) Since the coordinate has the minimum value and the x coordinate of the last coordinate has the maximum value, the display area can be divided.

If it is determined in step S415 that the display area can be divided according to the coordinates calculated from the input pointing signal, the controller 180 displays the coordinates of the display area according to the coordinates corresponding to the input pointing signal, The region is divided (S420), and the first image and the new second image are respectively displayed in the divided regions (S425). The second image may be the next image of the first image according to a preset priority, and may be selected when the display area is divided. The second image may include a broadcast moving picture, a photograph, a text, an object, and the like. For example, if the input pointing signal is a closed curve, the display area in which the first image is displayed in step S400 is divided based on the closed curve, and the first image and the new second image are displayed do.

The first image and the second image can maintain the original aspect ratio, and the original image ratio can be changed according to the ratio of the divided display areas. If the form of the divided display area and the form of the original are different, only a part of the original can be displayed in the divided display area.

On the other hand, the size of the divided display area can be changed. When a directional pointing signal is inputted through the boundary area of the divided display area and the boundary area is changed, the display area is re-divided according to the position of the changed boundary area according to the input pointing signal.

The divided display areas operate in different display areas and can display different broadcast images. In addition, the images displayed in the divided display areas can be separately controlled by the spatial remote controller 201. [

It is determined whether the pointing signal is input again from the spatial remote controller 201 through the divided first display region or the divided second display region after displaying the first image and the second image in the divided display regions in step S425 S430). As a result of the determination in step S430, when a pointing signal is input, the controller 180 calculates coordinates from the input pointing signal and repeats steps S415 through S440 using the calculated coordinates.

For example, when the pointing signal is input through the divided second display area, it is determined whether the second display area divided by the input pointing signal can be divided. If the input pointing signal has a closed curve shape, the divided second display area can be divided. Whether or not the divided second display area can be divided can be confirmed by the first coordinate and the last coordinate corresponding to the input pointing signal. At least one of the x-coordinate and the y-coordinate has a minimum value or a maximum value at the calculated first coordinate (x, y), and at least one of the x-coordinate and the y-coordinate in the last calculated coordinate (x, y) It can be determined that the display area can be divided. The minimum or maximum value of the x-coordinate and the y-coordinate may be an x-coordinate or a y-coordinate corresponding to the boundary of the divided second display area.

5 is a flowchart illustrating an operation method of an image display apparatus according to a second embodiment of the present invention.

As shown in FIG. 5, a first image is displayed in the display area of the display 170 (S500). The display area may be all or part of one side of the display 170.

Next, the control unit 180 selects the PIP generation menu by the signal input from the spatial remote controller 201 (S505). When the PIP creation menu is selected, various frames that can be in the form of a PIP are displayed on the display 170. The frame displayed on the display 170 may be a rectangle, a triangle, a heart, a star, or the like, and the user may generate a frame shape. That is, a pointing signal in the form of a closed curve is input in advance to generate a frame, and when the PIP menu is selected, the generated frame is displayed on the display 170.

Next, a signal for selecting a frame from the spatial remote controller 201 is input (S510). The control unit 180 selects a frame according to the input pointing signal, and displays the selected frame so as to overlap the first image (S515). The selected frame can be dragged by the pointing signal and displayed at the dragged position. When a frame is selected, the position at which the frame is to be displayed and the size to be displayed can be selected.

The PIP generation menu and the frame may be selected through at least one of the pointing signal and the selection signal transmitted from the spatial remote controller 201 and the position at which the frame is to be displayed and the size to be displayed may be selected.

Next, the controller 180 displays the second image at the position where the selected frame is displayed (S520). The size of the second image is the same as the size of the frame selected in step S510. The second image may be a broadcast moving picture, a picture, a text, an object, and the like. On the other hand, each of the second images can maintain the original image ratio, and the image ratio of the original image can be changed according to the selected frame. If the selected frame and the original shape of the second image are different, only a part of the original may be displayed in the area where the selected frame is displayed.

On the other hand, the size of the selected frame can be changed. When a directional pointing signal is input through the boundary area of the selected frame and the boundary area is changed, the size of the selected frame or the shape of the frame may be changed according to the position of the changed boundary area according to the input pointing signal. Therefore, when the shape or size of the frame is changed, the display of the second image is also changed.

Next, the control unit 180 determines whether another frame is selected (S525). If another frame is selected, steps S515 to S520 are repeated.

6 is a flowchart illustrating an operation method of an image display apparatus according to the third embodiment of the present invention.

As shown in FIG. 6, the first image is displayed in the display area of the display 170 (S600). Next, when the PIP generation menu is selected using the signal input from the spatial remote controller 201, the control unit 180 displays a frame (S605). Next, a directional pointing signal is input from the spatial remote controller 201, a frame is selected in accordance with the input pointing signal, and a position and a size of the selected frame are selected (S610). The frame displayed on the display 170 may be a rectangle, a triangle, a heart, a star, or the like, and the user may generate a frame shape.

The PIP generation menu and the frame may be selected through at least one of the pointing signal and the selection signal transmitted from the spatial remote controller 201 and the position at which the frame is to be displayed and the size to be displayed may be selected.

Next, the control unit 180 divides the display area in consideration of the position and size of the frame selected in step S610 (S615). For example, the display area may be divided into a minimum area and a remaining area where the selected frame can be maintained. In addition, the display area can be divided based on the minimum width at which the selected frame can be maintained.

Next, the control unit 180 displays a new second image at a position where the selected frame is displayed, and displays the first image in an area where the selected frame is not displayed, at step S620. At this time, since the position and size of the selected frame are maintained, the second image is displayed in the same form as the selected frame. For example, when a triangular frame is selected, the display area is divided based on the minimum width at which the triangular frame is displayed, and the second image is displayed in a triangular shape.

The second image can maintain the original aspect ratio of each original, and the original image ratio can be changed according to the selected frame to be displayed. If the selected frame and the original shape of the second image are different, only a part of the original may be displayed in the area where the selected frame is displayed.

On the other hand, the size of the selected frame can be changed. When a directional pointing signal is input through the boundary area of the selected frame and the boundary area is changed, the size of the selected frame or the shape of the frame may be changed according to the position of the changed boundary area according to the input pointing signal. In this case, the display area is re-divided according to the size and shape of the changed frame. For example, when the size of the changed frame is enlarged, the area of the divided display area where the selected frame is not displayed is reduced. That is, the display area is divided into the minimum area and the remaining area where the changed frame can be maintained.

When the shape or size of the frame is changed, the display of the second image is also changed.
