It is also within the scope of the present invention to further design a voice processing unit (not shown) and a data processing unit (not shown).

The demultiplexer 410 demultiplexes the input stream. For example, when an MPEG-2 TS is input, it can be demultiplexed into video, audio, and data signals, respectively.

The image processing unit 420 may perform image processing of the demultiplexed image signal. To this end, the image processing unit 420 may include a video decoder 421 and a scaler 422. The video decoder 421 decodes the demultiplexed video signal, and the scaler 422 performs scaling so that the resolution of the decoded video signal can be output from the video output unit. The video signal decoded by the video processing unit 420 is input to the mixer 450.

The OSD generation unit 440 generates an OSD signal according to a user input or by itself. Accordingly, the mixer 450 can mix the OSD signal generated by the OSD generating unit 440 and the decoded video signal processed by the image processing unit 420.

The mixed signal is provided to the formatter 460. Since the decoded broadcast video signal or the external input signal and the OSD signal are mixed, the OSD can be overlaid on the broadcast image or the external input image.

A frame rate converter (FRC) 455 can convert the frame rate of an input image. For example, a frame rate of 60 Hz is converted to 120 Hz or 240 Hz.

The formatter 460 receives the output signal of the frame rate conversion unit 455, changes the format of the signal to be suitable for the video output unit, and outputs the signal. For example, the R, G, and B data signals may be output as low voltage differential signaling (LVDS) signals or mini-LVDS signals.

That is, the user can realize the effect of comparing the images having different metadata by making the specific area touched by touching a specific area of the image for a predetermined or longer time.

23 is a view for explaining an example in which a display device according to an embodiment of the present invention outputs a GUI for comparing two or more images.

23 (a), the display device 2300 according to an exemplary embodiment of the present invention outputs a first image 2310, and upon receiving a command of a predetermined user, displays a first metadata icon 2320, a second metadata icon 2321, and a third metadata icon 2322. When the display device 2300 according to an embodiment of the present invention receives a signal for dragging the first metadata icon 2320 and the third metadata icon 2322 downward, (B) of FIG. 23, a second metadata change information 2320 is displayed on the second image 2310, which changes part or all of the metadata included in the first image 2310 based on the first metadata change information connected to the first metadata icon 2320, A third image 2312 that has changed some or all of the metadata contained in the first image 2310 based on the third metadata change information associated with the third metadata icon 2322, ). The display device 2300 generates a GUI for outputting and comparing the second image 2311 and the third image 2312 at the same time, and outputs the generated GUI through the display module.

In the case of such a design, there is an advantage that the user can compare the pictures to which the respective metadata change information is applied by using a simple drag operation.

24 is a view for explaining an example of displaying an indicator indicating information that a part or all of the metadata is changed in a specific area of an image according to an embodiment of the present invention.

The controller of the display device 2400 according to an embodiment of the present invention generates an indicator indicating information on a part or all of the metadata included in the first image changed to generate the second image, So as to display the indicator in the specific area of the second image.

24, when a part or the whole of the metadata included in the first image is changed to generate the second image, the display device 2400 according to an embodiment of the present invention may be configured such that, (2410, 2411) indicating information on a part or all of the metadata included in the first image changed to generate the second image in a specific area of the first image, and displays the generated indicator. For example, in the case of FIG. 24 (a), the second image was generated by changing the brightness level from 5 to 3 among the metadata included in the first image, and in the case of FIG. 24 (b) Is generated by changing the brightness level of the metadata included in the first image from 5 to 3 and changing the contrast level from 3 to 5.

In the case of such a design, there is an effect that it is possible to easily grasp which edit process the user is currently outputting through the image.

FIG. 25 is a view for explaining an example in which a display device according to an embodiment of the present invention performs a return operation and outputs an original image again.

25A, a display device 2500 according to an embodiment of the present invention changes a part or all of the metadata included in the first image 2511 to generate a second image 2510, And a return icon 2520 may be displayed in a specific area of the second image 2510 when the generated second image 2510 is outputted through the display module. 25 (b), the display device 2500 according to the embodiment of the present invention detects the first image 2511 when the user senses a signal to select the return icon 2520, Is output again. For example, as shown in FIG. 25, the user may change the brightness level of the metadata included in the first image 2511 from 5 to 3, change the contrast level from 3 to 5, , The display device 2500 changes the contrast level of the metadata included in the second image 2510 from 5 to 3 again, and when the brightness level (brightness level) Is changed back from 3 to 5 to regenerate the first image 2511 and output the first image 2511. That is, there is an advantage that the return icon 2520 can be used to return to the original image at a time.

26 is a flowchart showing a method of controlling a display device according to an embodiment of the present invention. With reference to FIG. 1 to FIG. 25, a supplementary analysis of FIG. 26 is possible.

26, a display device according to an embodiment of the present invention outputs a first image (S2600), and based on a command of a predetermined user, displays a part of the metadata included in the first image Or at least one metadata icon for changing all or a part of the metadata included in the first image (S2610), and displays a GUI including at least one metadata icon for changing a part or all of the metadata included in the first image (S2620), detects metadata change information associated with the selected specific metadata icon (S2630), and detects metadata change information associated with the selected meta data icon based on the detected metadata change information A second image is generated by changing a part or all of the data (S2640), and the generated second image is output (S2650).

Furthermore, although the drawings are shown for convenience of explanation, it is also possible to design a new embodiment to be implemented by merging the embodiments described in each drawing. And the display device and the control method thereof according to the embodiment are not limited to the configuration and the method of the embodiments described above as described above. That is, the above-described embodiments may be configured so that all or some of the embodiments may be selectively combined so that various modifications may be made.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It is to be understood that various modifications may be made by those skilled in the art without departing from the spirit and scope of the present invention.

In this specification, both the invention and the method invention are explained, and the explanation of the two terms may be supplementarily applied as necessary.
