Abstract

A display device may include memory storing at least one instruction that, when executed by at least one processor, cause the display device to: obtain a first screen capture image having a first data format; change a data format for the first screen capture image from the first data format to a second data format comprising a transparency element; transparentize a video area associated with the first video image in the first screen capture image by adjusting a value of the transparency element for the video area; generate a second synthesized image based on a second screen capture image comprising the transparentized video area and the first video image or a second video image following the first video image; and blur the second synthesized image.

First claim

What is claimed is:

1 . A display device, comprising:
a display; at least one processor; and memory storing at least one instruction that, when executed by the at least one processor, cause the display device to:
obtain a first screen capture image having a first data format by capturing a first synthesized image generated based on a first video image and at least one graphic image using a screen capture method, wherein the first data format does not comprise a transparency element indicating transparency;
change a data format for the first screen capture image from the first data format to a second data format comprising the transparency element;
transparentize a video area associated with the first video image in the first screen capture image by adjusting a value of the transparency element for the video area, based on data of the second data format;
generate a second synthesized image based on a second screen capture image comprising the transparentized video area and the first video image or a second video image following the first video image, wherein an area where the first video image or the second video image is displayed in the second synthesized image is in the transparentized video area;
blur the second synthesized image; and
control the display to display at least a portion of the blurred second synthesized image.

2 . The display device of claim 1 , wherein the at least one graphic image comprises a first graphic image and a second graphic image, and wherein a window comprising the first graphic image and a window comprising the second graphic image are positioned in different layers.

3 . The display device of claim 1 , wherein obtaining the screen capture image is performed before a blur application associated with the blurring or graphic information associated with the blur application is displayed on a screen.

4 . The display device of claim 1 , wherein the first data format is a YUV data format, and the second data format is an RGBA data format.

5 . The display device of claim 4 , wherein to transparentize the video area, the at least one instruction, when executed by the at least one processor, further cause the display device to adjust an alpha value of pixels corresponding to the video area to 0 in data of the second data format.

6 . The display device of claim 1 , wherein the second video image corresponds to a post-capture image obtained by capturing a video image scaled for synthesis with the at least one graphic image using a video capture method, and
wherein the second video image has the first data format.

7 . The display device of claim 4 , wherein the second synthesized image is generated by positioning the second video image in a lower layer than a layer comprising the second screen capture image.

8 . The display device of claim 1 , wherein to blur the second synthesized image, the at least one instruction, when executed by the at least one processor, further cause the display device to:
apply a blur effect to the second synthesized image; and output graphic information associated with a blur application supporting the blurring on the second synthesized image to which the blur effect is applied.

9 . The display device of claim 1 , wherein, after blurring the second synthesized image, the at least one instruction, when executed by the at least one processor, further cause the display device to:
generate a third synthesized image by synthesizing a third video image following the second video image with the screen capture image including the transparentized video area; and blur the third synthesized image, and
wherein the at least one graphic image is configured to be sequentially displayed on one screen with each of the first video image, the second video image, and the third video image.

10 . The display device of claim 1 , wherein the at least one graphic image comprises at least one graphic information, and
wherein the at least one graphic information is in a graphic area positioned outside the video area in the first screen capture image, and comprises at least one of a user interface, menu information, configuration information, user guide information, electronic program guide information, or notification information.

11 . The display device of claim 1 , wherein the first video image and the at least one graphic image have different data formats, and
wherein the first video image and the first screen capture image have the same data format.

12 . The display device of claim 1 , wherein the at least one instruction, when executed by the at least one processor, further cause the display device to:
identify an event related to the blurring; and obtain the first screen capture image based on identifying the event related to the blurring.

13 . A method of a display device, the method comprising:
obtaining a first screen capture image having a first data format by capturing a first synthesized image generated based on a first video image and at least one graphic image using a screen capture method, wherein the first data format does not comprise a transparency element indicating transparency; changing a data format for the first screen capture image from the first data format to a second data format comprising the transparency element; transparentizing a video area associated with the first video image in the first screen capture image by adjusting a value of the transparency element for the video area, based on data of the second data format; generating a second synthesized image based on a second screen capture image comprising the transparentized video area and the first video image or a second video image following the first video image, wherein an area where the first video image or the second video image is displayed in the second synthesized image is in the transparentized video area; blurring the second synthesized image; and displaying at least a portion of the blurred second synthesized image.

14 . The method of claim 13 , wherein the at least one graphic image comprises a first graphic image and a second graphic image, and
wherein a window comprising the first graphic image and a window comprising the second graphic image are positioned in different layers.

15 . The method of claim 13 , wherein the first data format is a YUV data format, and the second data format is an RGBA data format, and
wherein transparentizing the video area comprises adjusting an alpha value of pixels corresponding to the video area to 0 in data of the second data format.

16 . The method of claim 13 , wherein obtaining the first screen capture image is performed before a blur application associated with the blurring or graphic information associated with the blur application is displayed on a screen.

17 . The method of claim 13 , wherein the second video image corresponds to a post-capture image obtained by capturing a video image scaled for synthesis with the at least one graphic image using a video capture method, and
wherein the second video image has the first data format.

18 . The method of claim 13 , wherein the second synthesized image is generated by positioning the second video image in a lower layer than a layer comprising the second screen capture image.

19 . The method of claim 13 , wherein blurring the second synthesized image comprises:
applying a blur effect to the second synthesized image; and outputting graphic information associated with a blur application supporting the blurring on the second synthesized image to which the b
