Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 7 to 16. FIG.

Although the embodiments described below are described as being applied to a broadcast receiving apparatus that receives content from a content provider via a network, that is, a network TV, the present invention is not limited thereto. The present invention can be applied to an image processing apparatus or a display apparatus.

7 is an exemplary diagram showing a screen output by the image processing apparatus 30 according to an embodiment of the present invention.

The image processing apparatus 30 according to an embodiment of the present invention includes an image processing unit 43 for processing an object that can be identified by the user and a pointer indicating a point where the user is pointing, And a controller 50 for changing the configuration of the image associated with the pointer so that an overlapped portion of the object is visible when the pointer overlaps with the object.

According to an embodiment, the image processing apparatus 30 may further include a display unit 44 for outputting a video signal processed by the image processing unit 43.

For example, when the image processing apparatus 30 of the present invention is the network TV described above, the display unit 44 may be provided to output the image signal processed by the image processing unit 43. However, the present invention is not limited thereto, and may include devices that do not have the display unit 44, such as a main body of a computer, but are connected to a predetermined display module and output a video signal.

The image processing unit 43 processes an object identifiable by a user and a pointer indicating a point at which the user points.

As a result, the image signal output from the image processing unit 43 is outputted through the display unit 44 and can display an image as shown in FIG.

As shown in FIG. 7, the display unit 44 displays objects 22, 23, 24, and 26 that can be identified by the user and a pointer 21 indicating a point where the user is pointing.

7 is a screen for accessing a content provider, for example, 'YouTube' of the image processing apparatus 30 of the present invention and displaying a list of contents provided by the content provider.

The user can move the pointer 21 within the screen using the above-described motion recognition remote controller, and thus the pointer 21 indicates a point where the user is pointing.

According to one embodiment of the present invention, the objects 22, 23, 24, 26 identifiable by the user are text 26 such as "YouTube" shown in FIG. 7 or images 22, .

According to an embodiment, the object may be a hyperlink. For example, when the image processing apparatus 30 of the present invention is a computer and a user accesses a predetermined web site via the Internet, the object may be a hyperlink included in the web site.

The user input unit 47 receives an input of a user moving the pointer 21. That is, the user input unit 47 receives a radio signal indicating the motion of the user detected by the motion detection remote controller, for example, an infrared signal or an RF signal.

The pointer 21 moves within the screen according to the received user input.

When the pointer 21 overlaps with the objects 22, 23, 24 and 26, the controller 50 controls the pointer 21 so that the overlapped portions of the objects 22, 23, 24, And changes the configuration of the image associated with the image.

8, when the pointer 21 moves according to a user input and overlaps with the image 22 of the content 1, the control unit 50 determines that the overlapped The configuration of the image associated with the pointer 21 is changed.

According to an embodiment of the present invention, the controller 50 may reduce the size of the pointer 21 when the pointer 21 overlaps with the objects 22, 23, 24, and 26.

For example, as shown in FIG. 8, the pointer 21 located on the content 1 22 may be smaller than the pointer shown in FIG.

As a result, if the pointer 21 overlaps with the objects 22, 23, 24, and 26, a part or all of the objects 22, 23, 24, and 26 are hidden by the pointer 21 And can improve the readability of the user's screen.

According to an embodiment of the present invention, the controller 50 may change the configuration of the image related to the pointer according to the sizes of the objects 22, 23, 24, and 26.

In other words, the controller 50 can change the size of the pointer according to the size of the object overlapping with the pointer 21. [

For example, as the size of the object overlapping with the pointer 21 is smaller, the controller 50 can reduce the size of the pointer 21 in proportion to the sizes of the objects 22, 23, have. That is, as the sizes of the objects 22, 23, 24, and 26 overlapping with the pointer 21 are smaller, the size reduction amount of the pointer 21 can be larger.

9, if the pointer 21 moves from the first content 22 to the second content 23 and overlaps with the second content 23, The size becomes smaller than the size when it overlaps with the content 1 (22). In other words, the smaller the size of the object, the smaller the size of the pointer.

10, when the pointer 21 moves to and overlaps with the content 3 24, the size of the pointer 21 is larger than the size of the content 21 when it overlaps with the content 1, 2 (22, 23) Size. In Fig. 10, the size of content is reduced in the order of content 3, content 1, and content 2.

Accordingly, when the pointer 21 overlaps with the objects 22, 23, 24, and 26, the size is reduced to improve the readability of the user, Depending on the size of the substrate.

11 is an exemplary diagram for comparing the sizes of the changed pointers 21 according to an embodiment of the present invention.

11, the size of the pointer 212 overlapped with the content 1 is smaller than that of the default pointer 211 that is not overlapped with the objects 22, 23, 24, The pointer 213 overlapped with the content 2 having a smaller size is smaller than the pointer 212 whose size overlaps with the content 1. [ Since the content 3 is larger than the content 1 and 2, the size of the pointer 214 overlapped with the content 3 is larger than the size of the pointers 212 and 213 overlapped with the content 1 and 2. However, the pointer 214 overlapping with the content 3 has a smaller size than the default pointer 211. [

As described above, according to the embodiment of the present invention, the size of the pointer 21 may be reduced when overlapping with the text object as well as the image object.

12, when the pointer 21 overlaps the text 21 displayed on the display unit 44, i.e., 'YouTube', the control unit 50 controls the pointer It is possible to reduce the size of the display unit 21.

As described above, the size reduction amount of the pointer 21 may be dependent on the size of the objects 22, 23, 24, and 26. However, according to another embodiment of the present invention, The configuration of the image related to the pointer may be changed according to the area where the pointer 21 and the objects 22, 23, 24, and 26 overlap.

When the object is text, a predetermined area may be allocated to each text in the text. For example, as shown in FIG. 13, a predetermined area 25 including 'T' is allocated to 'T' in the text 'YouTube', and the pointer 21 is allocated to the text object The controller 50 may reduce the size of the pointer 21 according to an area where the area 25 allocated to the text and the pointer 21 overlap.

Specifically, an overlap area 251 is formed by the pointer 21 and the text area 25 while the pointer 21 moves in text as shown in FIG. 13 (a).

The area of the overlap area 251 increases as the pointer 21 moves in the text as shown in FIG. 13 (b).

The controller 50 may calculate the area of the overlap area 251 where the pointer 21 and the object area 25 overlap with each other and calculate the area of the overlaid area 251 The configuration of the pointer 21 can be changed according to the area.

13 (c), if the area of the overlap area 251 exceeds a predetermined value, for example, a certain ratio of the area of the pointer 21 or a certain percentage of the area of the object area 25 The controller 50 may reduce the size of the pointer 21. [

According to the embodiment, the controller 50 may gradually change the size of the pointer 21 according to the area of the overlap region 251. For example, as the pointer 21 moves to the object and the area of the overlap area 251 gradually increases, the controller 50 gradually increases the size of the pointer 21 to a predetermined minimum value Can be reduced.

According to an embodiment, the minimum value may be set differently according to the area 25 of the object. For example, as shown in FIG. 14, when the pointer 211 overlaps with a text having a larger size, the size may be larger than the size when the pointer 211 overlaps with text having a smaller size have.

In other words, the size of the pointer 21 may depend on the size of the areas 251 and 252 of the overlapping object.

According to another embodiment of the present invention, when the pointer 21 overlaps with the objects 22, 23, 24, and 26, the controller 50 can change the transparency of the pointer.

For example, as shown in FIG. 15, when the pointer 21 moves to the text object 26 and overlaps, the controller 50 may increase the degree of transparency of the pointer 21 .

As a result, the phenomenon that the pointer 21 overlaps with the objects 22, 23, 24, and 26 to cover the screen can be alleviated, and the readability of the screen of the user can be improved.

According to the embodiment, the controller 50 can change the transparency of the pointer 21 differently according to the size of the overlapping objects 22, 23, 24, and 26. For example, the smaller the size of the overlapping objects 22, 23, 24, and 26, the more the transparency of the pointer 21 can be increased.

According to another embodiment of the present invention, when the pointer 21 overlaps with the objects 22, 23, 24 and 26, the controller 50 controls the pointer 21 21) to change the subtitle description image including the subtitle description for the object (22, 23, 24, 26).

For example, as shown in FIG. 16A, when the pointer 21 is positioned on a predetermined object 22, the balloon help 27 (see FIG. 16A) including a subtle description of the object 22 in which the pointer 21 is located ) May be displayed.

According to the embodiment of the present invention, when the pointer 21 is overlapped with the object 22 as shown in FIG. 16 (b), the control unit 50 displays the balloon help displayed on the periphery of the pointer 21 The position of the object 27 can be changed so as not to overlap with the object 22.

According to the embodiment, it is possible to reduce the size of the pointer 21, increase the transparency of the pointer 21, or reduce the size of the pointer 21 by changing the configuration of the image related to the pointer 21, The embodiments of the present invention can be applied to the image processing apparatus 30 of the present invention individually or in combination of two or more.

Step S11 outputs a pointer 21 indicating an object identifiable by the user and a point at which the user points. That is, the image processor 43 processes the object and the pointer 21 and outputs the object and the pointer 21 to the display unit.

According to an embodiment, when the image processing apparatus 30 of the present invention includes a display unit, the image processing method may further include displaying the output object and the pointer.

According to an embodiment of the present invention, the object may include text, an image, or a hyperlink object.

Step S12 receives a user input for moving the pointer 21. [ That is, the user input unit 47 receives the radio signal including the motion information of the user detected by the motion detection remote controller.

The displayed pointer 21 moves within the screen according to the motion information included in the received radio signal.

Step S13 detects a state in which the pointer 21 overlaps with the object. That is, when the pointer 21 moves and overlaps with the object, the controller 50 detects this state.

Step S14 alters the configuration of the image associated with the pointer 21 such that an overlapping portion of the object is visible.

According to an embodiment of the present invention, the changing step may include reducing the size of the pointer 21 according to the size of the object.

According to another embodiment of the present invention, the changing step may include increasing the transparency of the pointer 21 according to the size of the object.

According to another embodiment of the present invention, the image associated with the pointer 21 is a balloon help 27 displayed when the pointer 21 is positioned over the object, And changing the position so as not to overlap with the object.

According to another embodiment of the present invention, the changing step may change the configuration of the image related to the pointer 21 according to the area where the pointer 21 and the object overlap.

For example, it may include continuously reducing the size of the pointer 21 as the area of the overlapping region increases.

In addition, if the area of the overlapped area exceeds a predetermined value, the size of the pointer 21 can be reduced to a predetermined size.

As described above, according to the present invention, when the user moves the pointer and the pointer overlaps with the object, the configuration of the balloon help displayed around the pointer 21 or the pointer 21 may be changed so that the readability of the screen may not be deteriorated .
