Along with the rapid development of science and technology, the multimedia field that combines various types of information such as video and audio, in the rapid development of information and communication, now called the digital revolution, the form of storage and existence of information is becoming digital from analog. Due to the development of MPEG (Moving Picture Experts Group) technology, which is a compression standard for moving image data to compress digital image data that requires a relatively large amount of data, the size of digital image data is gradually getting smaller. Increasingly, digital video and audio services have been applied to almost all fields such as communication and telecommunications, and digital devices for providing such services have emerged.

Among them, TV occupies an important place as an easy and effective information transmission medium in daily life, and thanks to the digital technology described above, video data and audio data are compressed and transmitted by MPEG technology, which makes a large amount of information faster and more stable. With the advent of digital TV, which can be provided by the user, more broadcasts can be easily enjoyed at home with clearer picture quality and more vivid sound.

Therefore, the capacity can be increased by 4 ~ 8 times compared to the existing analog method, and it is possible to provide services in various fields such as sports, movies, home shopping, and music. As the number of services increases, viewers can select and watch according to their own preferences, and viewers have a wider choice, and as a variety of broadcasts are provided, viewers can watch a desired broadcast by selecting a corresponding broadcast among many channels while watching TV. do.

As such, although the TV provides a variety of video information to the viewer, the TV does not necessarily provide only the video information that is beneficial to the viewer, but also provides disadvantageous video information to the viewer. Thus, to protect the viewer from such unfavorable video information, Methods of arbitrarily reducing the resolution, for example, a method of mosaicing and blurring, have been proposed. Here, the mosaicing method divides the screen into several horizontal and vertical grid shapes to make the pixel values in the grid the same, and the blurring method reduces the resolution of an image by filtering an area to be reduced in resolution. Way.

For example, Korean Laid-Open Patent Publication No. 2000-0054823 (published date: 2000.09.05) directly protects a portrait area by directly clicking a face area subject to portrait protection on a broadcast screen and performing image sampling using the skin area information of the surrounding area directly. By setting and saving the target area and using the set information to track the image of the next screen, set the minimum portrait protection target area on the video screen and remove unnecessary calculation process for scene change detection using the information of the set area. As a result, it is disclosed in a way that can significantly improve the speed of zoning of the portrait protection system.

However, the screen processing method as described above is only a mosaic process in order to protect the portrait rights of a specific person on the broadcaster side, because the viewer can not mosaic the harmful scenes themselves, the scenes harmful to the viewers are broadcast on TV as it is There is still this.

The present invention has been made to solve the above problems, and an object of the present invention is to drag a remote control having a pointer function to designate a specific area of an image screen being output on the screen, and then to mosaic the specific area dragged. A television receiver and method are provided.

Another object of the present invention is to provide a television receiver and a method for allowing a viewer to accurately mosaic a desired screen area by dragging and specifying a specific area of a video screen to be mosaiced with a remote controller.

It is still another object of the present invention to provide a television receiver and method capable of minimizing the time and procedure required for mosaic processing by performing mosaic processing on a designated screen area by dragging the remote control.

It is yet another object of the present invention to provide a television receiver and method that can protect certain viewers from harmful scenes by quickly and accurately specifying and mosaicing scenes that viewers, such as children, the elderly and pregnant women, should not see.

According to an aspect of the present invention, there is provided a television receiver for processing a mosaic on a video screen displayed on a screen, comprising: a storage unit for storing one or more mosaic image information having different mosaic processing levels; An image processor configured to designate an area dragged by a beam generated from a remote controller as a mosaic area, and to mosaic the mosaic area; And controlling the image processor to designate an area dragged by the beam generated by the remote controller as a mosaic area, wherein a mosaic image of one of the mosaic images stored in the storage unit overlaps the mosaic area, or controls the mosaic area.

The television receiver 100 of the present invention controls the tuning of each channel received through the tuner 101 and the storage unit 109 for storing various image and text information and for storing mosaic information, and a pointer. The image processing unit 107 is controlled to designate a screen area dragged by the remote controller having a function as a mosaic area, and the image processing unit is configured to overlap the mosaic image of the storage unit 109 in the mosaic area designated by the remote control. A control unit 110 for controlling 107 is provided.

The image processing unit 107 processes the video signal of the channel tuned through the tuner 101 under the control of the control unit 110 as a normal picture, and outputs it to the screen 102. Thus, the video signal is output to the screen 102. When the controller 110 instructs to designate an area dragged by the remote controller as the mosaic area while the image is being controlled, the image processing unit 107 is an area dragged by the beam generated from the remote control among the image screens being output to the screen 102. Is designated as the mosaic area. In this case, the image processing unit 107 displays the OSD border on the dragged mosaic area as shown in FIG. 2A so that the viewer can visually check the dragged area.

After the mosaic area is designated by the image processing unit 107 as described above, when the controller 110 transmits the mosaic image information stored in the storage unit 109 to the image processing unit 107 and instructs the mosaic processing, it is shown in FIG. 2B. As illustrated, the image processor 107 overlaps the mosaic image input under the control of the controller 110 to the mosaic area indicated by the OSD frame. If the controller 110 instructs only mosaic processing of the designated mosaic region without transferring the mosaic image stored in the storage unit 109 to the image processor 107, the image processor 107 distorts the screen of the mosaic region.

The storage unit 109 is a storage medium for storing various types of information, and may be implemented as a memory device such as RAM or EEPROM or a hard disk driver (HDD). Predetermined menu items are stored in 109, and various mosaic image information as shown in FIG. Here, the mosaic images shown in FIGS. 3A, 3B, and 3C respectively represent mosaic levels to be displayed on the screen, and the mosaic images shown in FIG. Among the mosaic images, the mosaic processing is the least, and the mosaic image shown in FIG. 3C is the highest mosaic level, and the mosaic processing is most performed among the three mosaic images. However, the type of mosaic to be processed on the screen according to the present invention is not limited thereto.

The controller 110 controls the mosaic processing on the mosaic area dragged by the remote controller, which will be described below.

The controller 110 controls the image processor 107 to designate a region dragged by the beam generated by the remote controller as the mosaic region, and accordingly, when the image processor 107 designates the region dragged by the remote controller as the mosaic region, The controller 110 transmits one mosaic image among the mosaic images stored in the storage unit 109 to the image processor 107 and instructs the mosaic processing. Here, the controller 110 transmits the mosaic image selected by the user from the mosaic image stored in the storage unit 109 to the image processing unit 107. If the user instructs the mosaic processing without selecting the mosaic image, the controller 110 ) Controls the image processor 107 to distort the mosaic region.

The controller 110 controls the image processor 107 to perform mosaic processing only during the mosaic processing time set by the user, but stops the mosaic processing from the user even before the set time elapses in the state where the mosaic processing is performed. When a command is input, the controller 110 controls the image processor 107 to stop the mosaic processing.

The process of mosaicing the mosaic region dragged by the remote controller with the television receiver of the present invention having the above-described configuration and function will be described with reference to a flowchart.

When the user selects a mosaic selection item by pressing a button on the remote controller (S402), the television receiver 100 displays predetermined mosaic image information as shown in FIG. 3 on the screen 102 (S403). In this state, when the user selects one mosaic image using the remote controller (S404), the television receiver 100 sets the mosaic image selected from the plurality of mosaic images for mosaic processing (S405).

Then, when the user presses the menu key on the remote control, the television receiver 100 displays the predetermined top menu items including the mosaic time item on the screen 102 (S406), in which the user presses a button on the remote control. When the mosaic time item is selected (S407), the television receiver 100 displays a screen window for receiving the mosaic processing time on the screen 102 (S408). If the user inputs a mosaic processing time, for example, 10 seconds, 15 seconds, 20 seconds, or 30 seconds in the time setting window using the remote control while the time setting window is displayed (S409), The receiver 100 sets the input time as a mosaic processing time (S410).

After the mosaic image to be mosaic-processed and the mosaic processing time are set, the television receiver 100 screens the image of the broadcast received from the broadcasting station or the image of the video input from an external device such as a DVD player and a video player. In the state of outputting on the screen (S411), when the user generates a beam from the remote control and drags a specific area on the screen (S412), as shown in FIG. 2A, the television receiver 100 displays an OSD border on the dragged screen area. Display (S413).

At this time, if the user instructs the mosaic processing by pressing a hot key attached to the remote control to instruct the mosaic processing (S414), as shown in Figure 2b, the television receiver 100 overlaps the mosaic image set in the mosaic area displayed OSD border (S415).

If there is no mosaic image set by the user, the television receiver 100 distorts the mosaic region without performing the overlap of the mosaic images in the overlapping process (S415).

In the state where the mosaic processing is performed in this way, the television receiver 100 determines whether the set mosaic processing time has elapsed (S416), and if so, stops the mosaic processing (S417).

If the mosaic processing time set in the determination process (S416) has not elapsed, the television receiver 100 determines whether an interruption command of the mosaic process is input from the user (S418), and if the interruption command is input, stops the mosaic process. (S419).

If no interruption command of the mosaic process is input in the determination process (S418), the television receiver 100 continues to overlap the mosaic image set in the dragged mosaic area.

On the other hand, the mosaic processing time is not necessarily set by the user, and the mosaic processing time may be set by default.

Although the technical spirit of the present invention has been described in detail according to the above-described preferred embodiment, it should be noted that the above-described embodiment is for the purpose of description and not of limitation. In addition, those skilled in the art will understand that various embodiments are possible within the scope of the technical idea of the present invention.
