Description

Technical Field

[0001] The present disclosure relates to a projection device supporting an edge blending function and a method for controlling the projection device. Background Art

[0002] Projection devices can be divided into analog projection devices that can provide visual information using a medium (e.g., film) and digital projection devices that can provide visual information using a digital signal. A representative example of a digital projection device is a light beam projector (hereinafter referred to as a "projector"). Projectors can be classified as display devices. Depending on how light is generated, a projector can be implemented as a cathode ray tube (CRT) projector, a liquid crystal display (LCD) projector, or a digital light processing (DLP) projector.

[0003] Projectors are mainly used to display input multimedia content as is, but with the development of wired / wireless communication networks, projectors can be connected to electronic devices (eg, digital TVs) to assist the electronic devices.

[0004] A projector is an electronic device that can project slides, photos, pictures, text, or images on a transparent sheet onto a screen through a lens. A projector is also called a projection device. A projector can convert document images or video data into an optical image and project or radiate it. The optical image projected or radiated by the projector can be displayed on a screen.

[0005] The size of the picture displayed by the projector may be limited by the supported resolution, contrast or brightness. Edge blending can be a method used to overcome such picture size limitations.

[0006] Edge blending may be used to adjust brightness or color of a blending area, which is an overlapping area between images projected by different projectors for upscaling a picture using at least two projectors without loss of resolution, contrast, or brightness. Summary of the Invention

[0027] Embodiments of the present disclosure will now be described with reference to the accompanying drawings in such detail as to be practiced by one of ordinary skill in the art. However, the present disclosure may be implemented in various other forms and is not limited to the embodiments set forth herein. Throughout the specification and drawings, the same or similar reference numerals may be used to refer to the same or similar elements. In addition, for the sake of clarity and brevity, well-known functions and configurations are not described in the drawings and related descriptions.

[0028] Figure 1 is a view showing a configuration of a display system 1 supporting an edge blending function according to an embodiment.

[0029] refer to Figure 1 , the display system 1 can provide an edge-blended screen using an edge-blending function. The edge-blending function corresponds to a function in which a plurality of projectors (e.g., a first projector 10 and a second projector 20) together project an optical image corresponding to an edge-blended image so as to display an image according to a common purpose such as a movie projection on a screen 30. The edge-blended image can be, for example, an image displayed by combining an optical image projected by the first projector 10 (hereinafter referred to as "first projected image 13") and an optical image projected by the second projector 20 (hereinafter referred to as "second projected image 23"). The edge-blended image can be a full display image made of the first projected image and the second projected image. In the following description, it is assumed that the edge-blended image is displayed on the screen 30, but it can be displayed on a flat surface, such as a wall, instead of the screen 30.

[0030] According to an embodiment, the display system 1 may include at least two image projection devices or screens 30. For example, the display system 1 may include a first image projection device (hereinafter referred to as "first projector 10") and a second image projection device (hereinafter referred to as "second projector 20"). The first projector 10 may be a first beam projector. The second projector 20 may be a second beam projector.

[0031] The first projector 10 may include a first light output unit 11. The first projector 10 may project a first projection image 13 toward a screen 30 through the first light output unit 11. Projecting may mean, for example, that a light beam corresponding to the first projection image 13 is radiated toward the screen 30. The first projection image 13 may allow a first partial display image P1 to appear in a first partial display area 31 provided on the screen 30.

[0032] The second projector 20 may include a second light output unit 21. The second projector 20 may project a second projection image 23 toward the screen 30 through the second light output unit 21. Projecting may mean, for example, that a light beam corresponding to the second projection image 23 is radiated toward the screen 30. The second projection image 23 may allow the second partial display image P2 to appear in the second partial display area 33 provided on the screen 30.

[0033] The edge-blended image displayed on screen 30 by first projected image 13 output by first projector 10 and second projected image 23 output by second projector 20 may include a fused image. The fused image may be an image displayed in fused region 35 where first partial display region 31 and second partial display region 33 overlap within the display area of ​​screen 30. To this end, first projector 10 and second projector 20 may allow the optical image corresponding to the fused image to be displayed in fused region 35 to have characteristics such as resolution or contrast that differ from those of the optical image corresponding to the image to be displayed in another region. This is to prevent the sharpness of the fused image from being reduced due to the overlapping and displaying of first projected image 10 and second projected image 20.

[0034] The first projection image 13 output by the first projector 10 may display the target image in a partial area (eg, the first partial display area 31) or the entire area 130 of the screen 30. For example, in a single operation (eg, Figure 3 In the case of a single operation 310 of the edge blending operation, the first projector 10 may output the first projection image 13 for displaying a picture in the entire area 130 of the screen 30 through the first light output unit 11. For example, in the edge blending operation (eg, Figure 3 In the case of the edge blending operation 320 , the first projector 10 may output the first projection image 13 for displaying a picture in the first partial display area 31 of the screen 30 through the first light output unit 11 .

[0035] The first projector 10 may establish a communication link with the second projector 20 based on at least one of wired or wireless communication with the second projector 20. For example, the first projector 10 may establish a communication link with the second projector 20 using a protocol supporting a direct wireless communication scheme such as Bluetooth or Wi-Fi.

[0036] The second projection image 23 output by the second projector 20 may display the target image in a partial area (eg, the second partial display area 33) or the entire area 130 of the screen 30. For example, in a single operation (eg, Figure 3 In the case of a single operation 310 of the screen 30, the second projector 20 may output the second projection image 23 for displaying a picture in the entire area 130 of the screen 30 through the second light output unit 21. For example, in an edge blending operation (eg, Figure 3 In the case of the edge blending operation 320 , the second projector 20 may output the second projection image 23 for displaying a picture in the second partial display area 33 of the screen 30 through the second light output unit 21 .

[0037] The second projector 20 may establish a communication link with the first projector 10 based on at least one of wired or wireless communication with the first projector 10. For example, the second projector 20 may establish a communication link with the first projector 10 using a protocol supporting a direct wireless communication scheme such as Bluetooth or Wi-Fi.

[0038] For example, the first projector 10 may function as a primary device or master device. For example, the second projector 20 may function as a secondary device or sub-device. The first projector 10 may perform a primary function as a primary device for displaying an edge-blended screen 130 on the screen 30 according to the edge-blending function. The primary function performed by the primary device may include, for example, determining an image to be projected by the primary device (hereinafter referred to as a "first partial display image") and an image to be projected by the secondary device (hereinafter referred to as a "second partial display image") in order to obtain an edge-blended image.

[0039] According to an example, if the edge blending function is activated, the first projector 10, together with the second projector 20, may perform an edge blending operation to display an edge-blended image on the screen 30. For example, when the first projector 10 operates as a primary device, the first projector 10 may determine a partial display image to be displayed by the first projector 10 and a partial display image to be displayed by the second projector 10 based on the edge-blended image. For example, when the first projector 10 operates as a primary device, the first projector 10 may transmit information about the first partial display image and / or the second partial display image to the second projector 20. For example, when the first projector 10 operates as a secondary device, the first projector 10 may receive information about the first partial display image and / or the second partial display image from the second projector 20.

[0040] First projector 10 may output first projection image 13 corresponding to the first partial display image to screen 30. First projection image 13 output by first projector 10 may allow the first partial display image as a first fused image to be displayed in first partial display area 31 of screen 30.

[0041] Second projector 20 may output second projection image 23 corresponding to the second partial display image to screen 30. Second projection image 23 output by second projector 20 may allow the second partial display image as a second fused image to be displayed in second partial display area 33 of screen 30.

[0042] According to an embodiment, the first partial display area 31 and the second partial display area 33 may jointly include an overlapping area (eg, Figure 1The fusion area 35 may be, for example, an area where the position or size of the second partial display area 33 overlaps with the third display area 225 in a predetermined area near at least one edge. o In the fusion area 35 , an image commonly included in the first partial display image P1 and the second partial display image P2 may be displayed.

[0043] exist Figure 2a FIG. 4 shows an example of an edge blending picture displayed on the screen 30 through the above-mentioned operations of the first projector 10 and the second projector 20. Figure 2a 2 also shows an example in which the first projector 10 or the second projector 20 configures a layout of a virtual screen to output an optical image.

[0044] According to an embodiment, if a GUI output request is generated after the edge blending function is activated, the first projector 10 can generate a virtual screen to provide a surplus area by reducing the area for displaying the first partial display image and the area for displaying the second partial display image together with the second projector 20. The first projector 10 can allocate the provided surplus area as the display area for displaying the GUI image. In this case, the first projector 10 can transmit information about the area in which the first partial display image and / or the second partial display image with the adjusted position or size are to be displayed to the second projector 20.

[0045] The first projector 10 may generate an image in which the first partial display image is located in the adjusted area and the GUI image is set in a specified position or size in the remaining area, and may output the image to the screen 30 through the light output unit 11. The first projected image 13 output by the first projector 10 may allow the GUI image and the first partial display image as the first fused image to be displayed in the first partial display area 31 of the edge-blended screen with the position and / or size changed.

[0046] Second projector 20 may output second projection image 23 to screen 30 so that the second partial display image is displayed in the adjusted area. Second projection image 23 output by second projector 20 may allow the second partial display image, as the second fused image, to be displayed in second partial display area 33 of the edge-blended screen with a changed position and / or size.

[0047] exist Figure 2b FIG. 4 shows an example of an edge blending picture displayed on the screen 30 through the above-mentioned operations of the first projector 10 and the second projector 20. Figure 2b 2 also shows an example in which the first projector 10 or the second projector 20 configures a layout of a virtual screen to output an optical image.

[0048] According to an embodiment, if a GUI output request is generated from the second projector 20 after the edge blending function is activated, the first projector 10 can generate a virtual screen to provide a remaining area by reducing the area for displaying the first partial display image and the area for displaying the second partial display image together with the second projector 20. The first projector 10 can allocate the provided remaining area as a display area for displaying the GUI image. In this case, the first projector 10 can transmit information about the area in which the second partial display image and / or the GUI image with an adjusted position or size is to be displayed to the second projector 20.

[0049] First projector 10 may output first projection image 13 to screen 30 so that the first partial display image is displayed in the adjusted area. First projection image 13 output by first projector 10 may allow the first partial display image as the first fused image to be displayed in first partial display area 31 of screen 30 with a changed position and / or size.

[0050] The second projector 20 may output a second projection image 23 to the screen 30 so that the second partial display image is displayed and the GUI image is displayed at a specified position or size in the remaining area. The second projection image 23 output by the second projector 20 may allow the GUI image and the second partial display image as the second fused image to be displayed in the second partial display area 33 of the screen 30 with the position and / or size changed.

[0051] exist Figure 2d FIG. 4 shows an example of an edge blending picture displayed on the screen 30 through the above-mentioned operations of the first projector 10 and the second projector 20. Figure 2d 2 also shows an example in which the first projector 10 or the second projector 20 configures a layout of a virtual screen to output an optical image.

[0052] According to an embodiment, when a GUI output request is generated sequentially or simultaneously from the first projector 10 and the second projector 20 after the edge blending function is activated, the first projector 10 may generate a virtual screen to reduce the area in which the first partial display image and the second partial display image are to be displayed, thereby providing a remaining area. The first projector 10 may allocate the first GUI display area for displaying the first GUI image to the first remaining area provided in the first partial display area 31. The first projector 10 may allocate the second GUI display area for displaying the second GUI image to the second remaining area provided in the second partial display area 33. In this case, the first projector 10 may transmit information about the area in which the second partial display image and / or the second GUI image with an adjusted position or size is to be displayed to the second projector 20.

[0053] The first projector 10 may output the first projection image 13 to the screen 30 so that the first partial display image is displayed in the adjusted area and the first GUI image is displayed in the first remaining area at a specified position or size. The first projection image 13 output by the first projector 10 may allow the first GUI image and the first partial display image as the first fused image to be displayed in the first partial display area 31 of the screen 30 with the position and / or size changed.

[0054] The second projector 20 may output a second projection image 23 to the screen 30 so that the second partial display image is displayed and the second GUI image is displayed at a specified position or size in the remaining area. The second projection image 23 output by the second projector 20 may allow the second GUI image and the second partial display image as the second fused image to be displayed in the second partial display area 33 of the screen 30 with the position and / or size changed.

[0055] exist Figure 2c FIG. 4 shows an example of an edge blending picture displayed on the screen 30 through the above-mentioned operations of the first projector 10 and the second projector 20. Figure 2c 2 also shows an example in which the first projector 10 or the second projector 20 configures a layout of a virtual screen to output an optical image.

[0075] According to an embodiment, the first projector 10 may transmit layout information 230-c to the second projector 20. The layout information 230-c may include information that allows the second projector 20 to arrange the second virtual GUI display area 221' and the second virtual partial edge-blended display area 225' on the virtual screen to output the second projection image 23. The second virtual GUI image 223' may be set in the second virtual GUI display area 221'. The second virtual partial edge-blended image 227' may be set in the second virtual partial edge-blended display area 225'.

[0076] Figure 2d FIG. 1 is a diagram showing a display system (eg, Figure 1 A view showing an example of an edge-blended screen including a second GUI displayed in the display system 1).

[0077] refer to Figure 2d , major equipment (e.g. Figure 1 The first projector 10) and auxiliary equipment (eg, Figure 1 The image is projected together with the second projector 20 of the screen 30 so that the edge-blended screen including the second GUI is displayed on the display area of ​​the screen 30 (for example, Figure 1 The edge blending screen including the second GUI may have a structure in which a display area allocated to each projector participating in the edge blending service is arranged (for example, according to Figure 6a (the arrangement structure of the fourth layout updated in operation 621).

[0078] For example, when two projectors (e.g. Figure 1 When the first projector 10 and the second projector 20 participate in the edge fusion service, the first projector 10 can transmit the optical image (for example, Figure 1 The first projection image 13) is projected onto an area (eg, Figure 1 For example, when two projectors (e.g., Figure 1 When the first projector 10 and the second projector 20 participate in the edge fusion service, the second projector 20 can transmit the optical image (for example, Figure 1 The second projection image 23 ) is projected onto one area (eg, the second partial display area (projection # 2 ) 33 ) included in the display area 130 .

[0079] The projection image (eg, Figure 1 The first partial display area 31 may include a first partial edge-blended display area 215. A first partial edge-blended image 217 of the first projection image 13 may be displayed in the first partial edge-blended display area 215. In this case, the first partial display image P1 may include the first partial edge-blended image 217. A GUI image (e.g., a GUI image 217) in which the first projector 10 can display the GUI image may be provided in advance in the first partial display area 31. Figure 2b The first GUI image 213) of the region (eg, Figure 2b first GUI display area 211).

[0080] By the projection image output by the second projector 20 (for example, Figure 1 The second partial display image P2 of the second projection image 23 may be displayed in the second partial display area 33. The second partial display area 33 may include the second GUI display area 221 and the second partial edge-blended display area 225. The second GUI image 223 of the second projection image 23 may be displayed in the second GUI display area 221. The second partial edge-blended image 227 of the second projection image 23 may be displayed in the second partial edge-blended display area 225. In this case, the second partial display image P1 may include the second GUI image 223 and the second partial edge-blended image 227.

[0081] According to an embodiment, the first projector 10 may determine a layout for providing a first virtual GUI display area 211' or a first virtual partial edge blending display area 215' on a virtual screen to output the first projection image 13. The first virtual partial edge blending image 217' may be set in the first virtual partial edge blending display area 215'. For example, the horizontal length l that defines the size of the virtual screen may be considered. 11 ' and vertical length l 12 ' and define the area to be displayed on the screen 30 (e.g. Figure 1 The horizontal length l of the size of the first partial display area 31) 11 and vertical length l 12 The ratio determines the layout.

[0082] According to an embodiment, the first projector 10 may transmit layout information 230-d to the second projector 20. The layout information 230-d may include information allowing the second projector 20 to arrange the second virtual GUI display area 221' and the second virtual partial edge-blended display area 225' on the virtual screen to output the second projection image 23. The second virtual GUI image 223' may be set in the second virtual GUI display area 221'. The second virtual partial edge-blended image 227' may be set in the second virtual partial edge-blended display area 225'. For example, the horizontal length l that defines the size of the virtual screen may be considered. 21 ' and vertical length l 22 ' and define the area to be displayed on the screen 30 (e.g. Figure 1 The horizontal length l of the size of the first partial display area 31) 21 and vertical length l 22 The ratio determines the layout.

[0083] Figure 3 FIG. 1 is a diagram showing a display system (eg, Figure 1 1) in a display system to switch the operation mode to display the Figure 1 A view 300 of the output screen is shown on the screen 30).

[0084] refer to Figure 3 , if the edge blending service is not provided because the edge blending function is not activated, the projector included in the display system 1 (eg, Figure 1 The first projector 10 or the second projector 20 may perform an operation according to the single operation 310. The single operation 310 may be, for example, each projector included in the display system 1 (eg, Figure 1The first projector 10 or the second projector 20 may operate independently. For example, in a single operation 310, only one of the first projector 10 or the second projector 20 may output a projected image to the screen 30. In this case, a screen based on the projected image output by the one projector may be displayed on the screen 30.

[0085] When the edge blending service request (330) is generated in operation 310, the projector (eg, Figure 1 The first projector 10 or the second projector 20 may switch states to perform an edge blending operation 320 .

[0086] The edge blending operation 320 may be, for example, a projector included in the display system 1 (eg, Figure 1 The first projector 10 or the second projector 20 may be used together to display an edge-blended image on the screen 30. For example, in edge-blending operation 320, the first projector 10 and the second projector 20 may cooperate with each other to output a projection image for displaying a target image. In this case, an edge-blended image based on the projection images output by at least two projectors may be displayed on the screen 30.

[0087] If the edge blending service termination request (340) is generated in the edge blending operation 320, the projector (eg, Figure 1 The first projector 10 or the second projector 20 ) may switch states to perform a single operation 310 .

[0088] Figure 4 FIG. 1 is a diagram showing a display system (eg, Figure 1 The display system 1) includes a projector (eg, Figure 1 The first projector 10) switches state to display the image on the screen (e.g., Figure 1 A view 400 of an edge-blended image is output on a screen 30 ).

[0090] In the default edge blending screen output state 410, the first projector 10 can communicate with at least one external projector (eg, Figure 1 The second projector 20) determines together with the second projector 20 a first partial display image to be displayed by itself (eg, Figure 2aThe first partial display image P1) and the second partial display image to be displayed in the target image by its counterpart (counterpart) (eg, Figure 2a The first partial display image P1 may include a first partial edge-blended image corresponding to a portion of the edge-blended image.

[0091] The first projector 10 may project an image corresponding to the first partial display image P1 (eg, Figure 1 The first projection image 13 outputted by the first projector 10 allows the first partial display image P1 as the first fused image to be displayed in the first partial display area 31 of the screen 30 .

[0092] In the default edge blending screen output state 410, the second projector 20 may project the image corresponding to the second partial display image P2 (eg, Figure 1 The second projection image 23 output by the second projector 20 allows the second partial display image P2 as the second fused image to be displayed in the second partial display area 33 of the screen 30.

[0093] The edge blending picture displayed on the screen 30 through the above operations of the first projector 10 and the second projector 20 can be as follows: Figure 2a shown.

[0094] According to an embodiment, if a GUI output request is received ( 411 ), the first projector 10 and the second projector 20 in the default edge-blending screen output state 410 may switch to an edge-blending screen output state 420 including the first GUI.

[0095] In the edge-blended screen output state 420 including the first GUI, the first projector 10 may generate a virtual screen and may provide a remaining area in the virtual screen. Figure 2b The first portion of the edge-fused image 217) has an area (eg, Figure 2b In this case, the first projector 10 may also consider reducing the first partial edge-blended display area 215, reducing the area used to display the partial edge-blended image to be included in the second partial display image P2 (for example, Figure 2b The second portion of the edge-fused image 227) has an area (eg, Figure 2bThe first projector 10 may allocate the remaining area provided by reducing the first partial edge-blended display area 215 for displaying a GUI image (eg, Figure 2b The display area (eg, the first GUI image 213) of Figure 2b first GUI display area 211).

The second layout may have a structure in which the first partial edge-blended image 217 is displayed in the first partial edge-blended display area 215 and the first GUI image 213 is displayed at a specified position or size in the first GUI display area 211. The first projection image 13 output by the first projector 10 may allow the first GUI image 213 and the first partial edge-blended image 217, which is the first fused image, to be displayed in the first partial display area 31 of the screen 30 at a changed position and / or size.

[0097] The second projector 20 in the edge-blended screen output state 420 with the first GUI may take into account the updated layout (e.g., Figure 6a The second layout (updated in operation 631) outputs the second projection image 23 to the screen 30. The second layout may have a structure in which the second partial edge-blended image 227 is displayed in the second partial edge-blended display area 225. The second projection image 23 output by the second projector 20 may allow the second partial edge-blended image 227, as the second fused image, to be displayed in the second partial display area 33 of the screen 30 at a changed position and / or size.

Figure 2b 2 also shows an example in which the first projector 10 or the second projector 20 configures a layout of a virtual screen to output an optical image.

[0099] According to an embodiment, if a GUI output termination request (421) is received in the edge blending screen output state 420 including the first GUI, the first projector 10 and the second projector 20 may switch back to the default edge blending screen output state 410. The first projector 10 and the second projector 20 that have switched to the default edge blending screen output state 410 may operate such that Figure 2a The illustrated first partial display image P1 and second partial display image P2 may be displayed on the screen 30 .

[0100] According to an embodiment, if a layout update request is received ( 413 ), the first projector 10 and the second projector 20 in the default edge-blending screen output state 410 may switch to an edge-blending screen output state 430 including a second GUI.

[0101] In the edge-blended screen output state 430 including the second GUI, the first projector 10 may generate a virtual screen and may provide a remaining area in the virtual screen. Figure 2d The second portion of the edge-fused image 227) has an area (eg, Figure 2d In this case, the first projector 10 may also consider the reduced second partial edge-blended display area 225, reducing the portion of the edge-blended image to be included in the first partial display image P1 (for example, Figure 2d The first portion of the edge-fused image 217) has an area (eg, Figure 2d The first projector 10 may allocate the remaining area provided by reducing the second partial edge-blended display area 225 for displaying a GUI image (eg, Figure 2d The display area of ​​the second GUI image 223) (for example, Figure 2d The first projector 10 may allocate the second remaining area for displaying a GUI image by the second projector 20 (eg, Figure 2c The display area of ​​the second GUI image 223) (for example, Figure 2c The second GUI display area 221).

[0102] The first projector 10 may consider the updated layout (e.g., Figure 6b The first projection image 13 is output to the screen 30 using the fourth layout obtained in operation 645. The fourth layout may have a structure in which the first partial edge-blended image 217 is displayed in the first partial edge-blended display area 215. The first projection image 13 output by the first projector 10 may allow the first partial display image P1, including the first partial edge-blended image 217 as the first fused image, to be displayed in the first partial display area 31 of the screen 30 at a changed position and / or size.

[0103] The second projector 20 in the edge-blended screen output state 430 containing the second GUI may take into account the updated layout (e.g., Figure 6bThe second projection image 23 is output to the screen 30 using the fourth layout obtained in operation 645 of the second projector 20. The fourth layout may have a structure in which the second partial edge-blended image 227 is displayed in the second partial edge-blended display area 225 and the second GUI image 223 is displayed at a specified position or size in the second GUI display area 221. The second projection image 23 output by the second projector 20 may allow the second GUI image 223 and the second partial edge-blended image 227 as the second fused image to be displayed in the second partial display area 33 of the screen 30 at a changed position and / or size.

[0104] exist Figure 2d FIG. 4 shows an example of an edge blending picture displayed on the screen 30 through the above-mentioned operations of the first projector 10 and the second projector 20. Figure 2d 2 also shows an example in which the first projector 10 or the second projector 20 configures a layout of a virtual screen to output an optical image.

[0105] According to an embodiment, if a layout restoration request (433) is received in the edge blending screen output state 430 including the second GUI, the first projector 10 and the second projector 20 may switch back to the default edge blending screen output state 410. The first projector 10 and the second projector 20 that have switched to the default edge blending screen output state 410 may operate such that Figure 2a The first partial display image P1 and the second partial display image P2 shown in FIG. 3 may be displayed on the screen 30 .

[0106] According to an embodiment, if a layout update request ( 423 ) is received, the first projector 10 and the second projector 20 in the edge-blending screen output state 420 including the first GUI may switch to the edge-blending screen output state 440 including the first and second GUIs.

[0107] In the edge-blended screen output state 440 including the first and second GUIs, the first projector 10 may generate a virtual screen and may provide a remaining area in the virtual screen. The remaining area may include a portion of the edge-blended image to be included in the first partial display image P1 (e.g., Figure 2c The first portion of the edge-fused image 217) has an area (eg, Figure 2c The first remaining area provided by the second partial edge-blended display area 225) and the first remaining area provided by reducing the area for displaying the partial edge-blended image to be included in the second partial display image P2 (for example, Figure 2c The second portion of the edge-fused image 227) has an area (eg, Figure 2cThe first projector 10 may allocate the first remaining area provided in the first partial display area 31 as a second remaining area for displaying a GUI image (eg, Figure 2c The display area (eg, the first GUI image 213) of Figure 2c The first projector 10 may allocate the second remaining area provided in the second partial display area 33 as a display area (e.g., a second GUI image 223 of FIG. 2C ) for displaying a GUI image (e.g., a second GUI image 223 of FIG. 2C ) by the second projector 20. Figure 2c The second GUI display area 221).

[0108] The first projector 10 may be considered to be updated to reflect the adjusted layout of the first partial display area 31 (e.g., in Figure 6b The first projection image 13 is output to the screen 30 using the third layout obtained in operation 639. The third layout may have a structure in which the first partial edge-blended image 217 is displayed in the first partial edge-blended display area 215 and the first GUI image 213 is displayed at a specified position or size in the first GUI display area 211. The first projection image 13 output by the first projector 10 may allow the first partial display image 210, including the first GUI image and the first partial edge-blended image 217 as the first fused image, to be displayed in the first partial display area 31 of the screen 30 at a changed position and / or size.

[0109] The second projector 20 in the edge-blended screen output state 440 containing the first and second GUIs may be considered to be updated to reflect the layout of the adjusted second portion of the display area 33 (eg, in Figure 6b The second projection image 23 is output to the screen 30 using the third layout obtained in operation 639. The third layout may have a structure in which the second partial edge-blended image 227 is displayed in the second partial edge-blended display area 225 and the second GUI image 223 is displayed at a specified position or size in the second GUI display area 221. The second projection image 23 output by the second projector 20 may allow the second GUI image 223 and the second partial edge-blended image 227 as the second fused image to be displayed in the second partial display area 33 of the screen 30 at a changed position and / or size.

Figure 2c 2 also shows an example in which the first projector 10 or the second projector 20 configures a layout of a virtual screen to output an optical image.

[0111] According to an embodiment, if a layout restoration request (443) is received, the first projector 10 and the second projector 20 in the edge fusion screen output state 440 containing the first and second GUIs may be switched back to the edge fusion screen output state 420 containing the first GUI. The first projector 10 and the second projector 20 that have switched to the fusion screen output state 420 containing the first GUI may operate so that Figure 2b The first partial display image P1 and the second partial display image P2 shown in FIG. 3 may be displayed on the screen 30 .

[0112] According to an embodiment, if a GUI output request (431) is received, the first projector 10 and the second projector 20 in the edge-blended screen output state 430 including the second GUI may be switched to the edge-blended screen output state 440 including the first and second GUIs. The first projector 10 and the second projector 20 that have switched to the edge-blended screen output state 440 including the first and second GUIs may perform the same operation as when switching from the edge-blended screen output state 420 including the first GUI to the edge-blended screen output state 440 including the first and second GUIs.

[0113] According to the embodiment, if a GUI output termination request (441) is received, the first projector 10 and the second projector 20 in the edge fusion screen output state 440 containing the first and second GUIs may be switched back to the edge fusion screen output state 430 containing the second GUI. The first projector 10 and the second projector 20 that have switched to the fusion screen output state 430 containing the second GUI may be operated so that Figure 2d The first partial display image P1 and the second partial display image P2 shown in FIG. 3 may be displayed on the screen 30 .

[0114] Figure 5 is a diagram showing a method for transmitting data by a projector (eg, Figure 1 For ease of description, the following description focuses on the first projector 10, but can also be applied to other displays (e.g., Figure 1 a second projector 20).

[0115] refer to Figure 5 In operation 510 or 520, the projector 10 may identify an operation configured to support edge fusion services (eg, Figure 3For example, in operation 510, the projector 10 may determine whether a primary operation is configured to be performed when providing an edge blending service. For example, the primary operation may be configured in at least one device (hereinafter, referred to as a "primary device") among the plurality of devices to provide the edge blending service together. For example, in operation 520, the projector 10 may determine whether a secondary operation is configured to be performed when providing the edge blending service. For example, the secondary operation may be configured in the remaining devices (hereinafter, referred to as "secondary devices") among the plurality of devices other than the at least one primary device to provide the edge blending service together.

[0116] The projector 10 may determine whether an edge blending service request has occurred before determining whether the projector 10 is configured to operate as a primary device or a secondary device for the edge blending service.

[0117] If the projector 10 is configured to operate as a primary device, then in operation 530, the projector 10 may execute a primary operation subroutine. The primary operation subroutine defines the operations to be performed by the primary device. For example, the primary device may Figure 6a and Figure 6b The control flow of execution operations.

[0118] If the projector 10 is configured to operate as an auxiliary device in an edge fusion service, then in operation 540, the projector 10 may execute an auxiliary operation subroutine. The auxiliary operation subroutine defines the operation to be performed by the auxiliary device. For example, the auxiliary device may Figure 7a and Figure 7b The control flow of execution operations.

[0119] According to an embodiment, the primary device may configure or update the layout of the edge fusion service. The primary device may configure the initial layout of the edge fusion service in response to an edge fusion service request. The primary device may configure the initial layout of the edge fusion service in response to a termination request for all GUI outputs. The primary device may update the existing layout in response to a GUI output request. The primary device may update the existing layout in response to a GUI output termination request. The primary device may update the existing layout in response to a layout update request from a secondary device. The initial layout or updated layout may be Figures 2a to 2d The main device may output a projection image based on an initial layout or an updated layout configured by the main device (e.g., Figure 1 The first projected image 13), the projected image is to be displayed on a screen (eg, Figure 1 visual information on the screen 30).

[0120] According to an embodiment, the secondary device may operate as a secondary device based on an initial layout or an updated layout provided by the primary device. The secondary device may transmit a layout update request to the primary device in response to a GUI output request. The secondary device may transmit a layout update request to the primary device in response to a GUI output termination request. The secondary device may receive a layout change request from the primary device in response to the layout update request. Even when a GUI output request or termination request is being made from the primary device, the secondary device may receive a layout change request from the primary device. The secondary device may update the existing layout in response to the layout change request received from the primary device.

[0121] The secondary device may output a projected image based on the initial layout or updated layout received from the primary device (e.g., Figure 1 The second projected image 23) is to be projected on a screen (eg, Figure 1 The visual information is displayed on the screen 30).

[0122] Figure 6a and Figure 6b is a diagram showing a method for use with a projector (eg, Figure 1 The first projector 10) operates as a primary device (e.g., Figure 5 However, the present disclosure is not limited thereto, and in reference to Figure 6a and Figure 6b In the following description, the projector 10 may be a secondary device, and the external projector 20 may be a primary device.

[0123] refer to Figure 6a and Figure 6b In operation 611, the projector 10 may determine whether a request for activating an edge blending function for using an edge blending service is received. This may be accomplished, for example, by providing a user interface unit (eg, Figure 8 The projector 10 receives a request for activating the edge blending function based on information inputted by the user interface unit 820. If the projector 10 receives the request for activating the edge blending function before the main operation subroutine is started, operation 611 may be omitted.

[0124] For example, if a request for activating the edge blending function is received, the projector 10 may request at least one external projector (eg, Figure 1The at least one external projector 20 may be an external electronic device that together performs edge blending services. When the projector 10 is a primary device, the at least one external projector 20 may be an auxiliary device. The at least one external projector 20 configured to operate as an auxiliary device may be preconfigured to provide edge blending services. The projector 10 may transmit information required for providing edge blending services (e.g., layout information) to the at least one external projector 20. The projector 10 may receive information required for providing edge blending services (e.g., layout information) from the at least one external projector 20.

[0125] For example, the projector 10 may receive a request to activate the edge blending function from the external projector 20. In this case, the projector 10 may receive information (e.g., layout information) required to provide the edge blending service from at least one external projector 20. The projector 10 may also transmit the information (e.g., layout information) required to provide the edge blending service to the at least one external projector 20.

[0126] The projector 10 may obtain or determine a first layout in operation 613. The first layout may define a display area of ​​the screen 30 (eg, Figure 1 The arrangement structure may allocate a display area to each projector participating in, for example, an edge blending service.

[0127] For example, when the first projector 10 and the second projector 20 participate in the edge blending service, the first layout may define two areas (eg, Figure 1 The first partial display area (projection #1) 31 and the second partial display area (projection #2) 33 (see Figure 2a A portion of the first partial display area 31 may overlap a portion of the second partial display area 33. One of the two areas (eg, Figure 1 The remaining one of the two areas (e.g., Figure 1 The first partial display area 31 may have the same size as the second partial display area 33. The horizontal length l of the first partial display area 31 11 For example, the horizontal length l of the second partial display area 33 may be 21 The vertical length l of the first display area 31 is the same as 12 For example, the vertical length l of the second partial display area 33 may be 22 same.

[0128] According to an embodiment, the first layout may include first position information or first size information indicating the first partial display area 31. The first position information may be information indicating the position where the first partial display area 31 is set in the display area 130 of the screen 30. The first position information may be defined by coordinate values ​​provided to divide the display area 130 of the screen 30 into blocks of predetermined sizes. The coordinate values ​​may be, for example, coordinate values ​​indicating each corner of the first partial display area 31. The first size information may include information about the horizontal length l 11 Or vertical length l 12 The first size information may include the area value of the first partial display area 31.

[0129] According to an embodiment, the first layout may include second position information or second size information indicating the second partial display area 33. The second position information may be information indicating the position where the second partial display area 33 is set in the display area 130 of the screen 30. The second position information may be defined by coordinate values ​​provided to divide the display area 130 of the screen 30 into blocks of predetermined sizes. The coordinate values ​​may be, for example, coordinate values ​​indicating each corner of the second partial display area 33. The second size information may include information about the horizontal length l 21 Or vertical length l 22 The second size information may include the area value of the second partial display area 33.

[0130] According to an embodiment, the first layout may include an overlapping area (eg, Figure 1 For example, the first layout may include third position information or third size information indicating the fusion area 35. The third position information may be information indicating the position where the fusion area 35 is set in the display area 130 of the screen 30. The third position information may be defined by coordinate values ​​provided to divide the display area 130 of the screen 30 into blocks of predetermined sizes. The coordinate values ​​may be, for example, coordinate values ​​indicating each corner of the fusion area 35. The third size information may include information about the horizontal length l o Or vertical length l 12 or l 22 The third size information may include the area value of the fusion region 35.

[0131] For example, the projector 10 may generate a virtual screen in response to a request for activating the edge blending function. The projector 10 may determine the first layout by setting the first partial display area 31, the second partial display area 33, or the blending area 35 on the generated virtual screen. The first partial display area 31 may include a first partial edge blending display area (e.g., Figure 2bThe second portion of the display area 33 may include a second portion of the edge-blended display area (eg, Figure 2b The second portion of the edge blending display area 225).

[0132] In operation 615, the projector 10 may output a projection image (eg, Figure 1 The projected image 13 may display a first partial edge-blended image 217 in a first partial edge-blended display area 215 on the screen 30. The first partial edge-blended image 217 may be a portion of an edge-blended screen to be displayed on the display area 130 of the screen 30 together with at least one external projector 20. The projector 10 may generate the first projected image 13, for example, by converting a portion of an image assigned to the projector 10 of the entire image to be provided by the edge-blending service into light. The entire image may be an edge-blended image to be displayed in the display area 130 of the screen 30 together with at least one external projector (e.g., the second projector 20). The projector 10 may configure the first partial edge-blended image 217 of the entire image corresponding to the portion of the image to be processed by the projector itself through a prior agreement with the at least one external projector 20.

[0133] In operation 617, the projector 10 may monitor whether a GUI output request is received. For example, the projector 10 may recognize that a GUI output request is received in response to receiving a command requesting execution of a setting program. The setting program may be, for example, a program for adjusting the settings of the edge blending function. For example, the user interface unit (e.g., Figure 8 The user interface unit 820 of the projector 10 may be used to input a command for requesting execution of the setting program. Figure 8 The control message is received by the communication unit 840 (e.g., the second projector 20) and receives a command requesting the execution of the setting program. The control message may be sent by an external electronic device (e.g., the second projector 20). The external electronic device may also be a portable terminal (e.g., a smartphone or a remote control) that can be operated by a user.

[0134] If the GUI output request is not monitored, the projector 10 may monitor whether a layout update request message is received in operation 619. The layout update request message may include layout update request information. The layout update request information may be sent by an external electronic device. The external electronic device may be another projector (e.g., a device that performs an operation together to provide an edge blending service) Figure 1 For example, the layout update request information may include information for changing the edge blending picture displayed on the screen 30 (eg, Figure 2a). The layout update request information may be provided by the occurrence of an event requiring a layout change. The event requiring a layout change may occur in the external projector 20. The event requiring a layout change may include, for example, an event for requesting the external projector 20 to display a GUI.

[0135] The layout update request information may include, for example, an instruction to the projector 10 to display the fused image therein (eg, Figure 2d The first portion of the edge-fused image 217) has an area (eg, Figure 2d For example, the information indicating the first partial edge-blended display area 215 may include position information or size information indicating the first partial edge-blended display area 215. The position information may be information indicating the position where the first partial edge-blended display area 215 is set in the first partial display area 31 of the screen 30. The position information may be defined by coordinate values ​​provided to divide the first partial display area 31 of the screen 30 into blocks of a predetermined size. The coordinate values ​​may be, for example, coordinate values ​​indicating an edge of the first partial edge-blended display area 215. The size information may include information about a horizontal length or a vertical length. The size information may include an area value of the first partial edge-blended display area 215.

[0136] If the Figure 1 If the second projector 20 receives the layout update request information, the projector 10 may determine a fourth layout obtained by updating the first layout in operation 621. The fourth layout may define an arrangement structure for displaying the second GUI image 223 in the second GUI display area 221 in the display area 130 of the screen 30 (see Figure 2d For example, when the first projector 10 and the second projector 20 participate in the edge blending service, the fourth layout may define the first partial edge blending display area 215 as being included in the first partial display area 31 of the screen 30. The fourth layout may define the second partial edge blending display area 225 and the second GUI display area 221 as being included in the second partial display area 33 of the screen 30.

[0137] According to an embodiment, the fourth layout may include position information or size information indicating the first partial edge-blended display area 215. The position information may be information indicating the position where the first partial edge-blended display area 215 is set in the first partial display area 31 allocated in the screen 30. The first position information may be defined by coordinate values ​​provided to divide the first partial display area 31 of the screen 30 into blocks of a predetermined size. The coordinate values ​​may be, for example, coordinate values ​​indicating the edge of the first partial edge-blended display area 215. The size information may include information about the horizontal length or the vertical length. The size information may include an area value of the first partial edge-blended display area 215.

[0138] According to an embodiment, the fourth layout may include position information or size information indicating the second partial edge fusion display area 225 and the second GUI display area 221. The position information may be information indicating the position at which the second partial edge fusion display area 225 or the second GUI display area 221 is set in the second partial display area 33 allocated in the screen 30. The position information may be defined by coordinate values ​​provided to divide the first partial display area 31 into blocks of a predetermined size. The coordinate values ​​may be, for example, coordinate values ​​indicating the edge of the second partial edge fusion display area 225 or the second GUI display area 221. The size information may include information about the horizontal length or the vertical length. The size information may include an area value of the second partial edge fusion display area 225 or the second GUI display area 221.

[0139] In operation 623, the projector 10 may send a layout change request message to at least one external projector 20 requesting a change to the fourth layout. The layout change request message may include layout change request information. The layout change request information may include all or part of the information about the fourth layout. The layout change request information may include, for example, position information or size information indicating the second portion of the edge-blended display area 225 and the second GUI display area 221 according to the fourth layout.

[0140] In operation 625, the projector 10 may output a projection image (eg, Figure 4The projected image 13 may display a first partial edge-blended image 217 in the updated first partial edge-blended display area 215 on the screen 30. The first partial edge-blended image 217 may be a portion of an edge-blended screen to be displayed on the display area 130 of the screen 30 together with the at least one external projector 20. The projector 10 may generate the first projected image 13, for example, by converting an image of a portion of the entire image to be provided by the edge-blending service, allocated to the projector 10, into light. The entire image may be an edge-blended image to be displayed on the display area 130 of the screen 30 together with the at least one external projector (e.g., the second projector 20). The first partial edge-blended image 217 to be displayed on the portion allocated thereto may be the same portion of the image considered as the output projection image in operation 615.

[0141] In operation 627, the projector 10 may monitor whether a signal is received from an external electronic device (eg, Figure 1 For example, the layout restoration request information may be received from another projector (e.g., the second projector 20) to perform operations together to provide edge blending services. For example, when an event occurs in the other projector that requires the layout of the edge blended image displayed on the screen 30 to be restored to the current layout, the layout restoration request information may be transmitted from the other projector. The layout restoration request information may include information about the operation to be performed before the projector 10 displays the fused image (e.g., Figure 2d The information about the first layout applied before the update of the first partial edge-blended image 217 is used. The information about the first layout may be the same as the information defined above.

[0142] If the layout restoration request information is received, the projector 10 may change the fourth layout corresponding to the information indicating the display area 130 of the screen 30 to the first layout in operation 629. The information about the first layout may be stored by the projector 10, for example. After changing to the first layout, the projector 10 may proceed to operation 615 to output the first projection image 13 toward the screen 30 based on the first layout to display the first partial edge-blended image 217 on the screen 30 to configure the edge-blended screen (see FIG. Figure 2a ).

[0143] If a GUI output request is monitored, the projector 10 may obtain or determine a second layout in operation 631. The projector 10 may obtain the second layout, for example, by updating the first layout.

[0144] According to an embodiment, the second layout may define a first partial display area (eg, Figure 2b The first partial display area 31) has a structure in which the first portion of the image is displayed in the first partial display area (for example, Figure 2b The first partial display image P1) will be displayed on the screen 30. The first partial display area 31 may have a setting in which the fused image (eg, Figure 2b The first portion of the edge-fused image 217) has an area (eg, Figure 2b The first portion of the edge blending display area 215) and the GUI image to be displayed (eg, Figure 2b The first GUI image 213) of the region (eg, Figure 2b The structure of the first GUI display area 211).

[0145] According to an embodiment, the second layout may define a second partial display area (eg, Figure 2b The second portion of the display area 33) has a structure in which the second portion of the display area displays the image (for example, Figure 2b The second portion of the edge display image P2) will be displayed on the screen 30. The second portion display area 33 may have a setting where the fused image (eg, Figure 2b The second portion of the edge-fused image 227) has an area (eg, Figure 2b The second part of the fusion display area 225) has a structure.

[0146] For example, when the first projector 10 and the second projector 20 participate in the edge blending service, the second layout may define, in the display area 130 of the screen 30, a first GUI display area 211 and a first partial edge blending display area 215 included in the first partial display area 31 allocated thereto (see Figure 2b The first GUI display area 211 may have a size different from that of the first partial edge blending display area 215. The second layout may define a second partial edge blending display area 225 (refer to FIG. 1 ) included in the second partial display area 33 allocated to the second projector 20 in the display area 130 of the screen 30. Figure 2b ).

[0147] Depending on the embodiment, the second layout may include position information or size information indicating the first GUI display area 211. The position information may be information indicating the location where the first GUI display area 211 is set within the first partial display area 31 allocated on the screen 30. The first position information may be defined by coordinate values ​​provided to divide the first partial display area 31 of the screen 30 into blocks of predetermined size. The coordinate values ​​may be, for example, coordinate values ​​indicating the edges of the first GUI display area 211. The size information may include information regarding the horizontal length or vertical length. The size information may include an area value of the first GUI display area 211.

[0148] According to an embodiment, the second layout may include position information or size information indicating the first partial edge-blended display area 215. The position information may be information indicating the position at which the first partial edge-blended display area 215 is set in the first partial display area 31 allocated in the screen 30. The position information may be defined by coordinate values ​​provided to divide the first partial display area 31 into blocks of a predetermined size. The coordinate values ​​may be, for example, coordinate values ​​indicating the edges of the first partial edge-blended display area 215. The size information may include information about the horizontal length or the vertical length. The size information may include an area value of the first partial edge-blended display area 215.

[0149] According to an embodiment, the second layout may include position information or size information indicating the second partial edge-blended display area 225. The position information may be information indicating the position where the second partial edge-blended display area 225 is set in the second partial display area 33 allocated on the screen 30. The position information may be defined by coordinate values ​​provided to divide the second partial display area 33 into blocks of a predetermined size. The coordinate values ​​may be, for example, coordinate values ​​indicating the edges of the second partial edge-blended display area 225. The size information may include information about the horizontal length or the vertical length. The size information may include an area value of the second partial edge-blended display area 225.

[0150] In operation 633, the projector 10 may project the image to at least one external projector (eg, Figure 1 The second projector 20 of FIG. 1 sends a layout change request message for requesting a change to the second layout. The layout change request message may include, for example, an area (eg, Figure 2b In the second partial edge-blended display area 225, in which the at least one external projector 20 is to display an edge-blended image in the second partial display area 33 allocated in the screen 30 in proportion to the first partial edge-blended display area 215 (e.g., Figure 2bThe projector 10 may allocate the first GUI display area 211 to display the first GUI image 213 , and the position or area of ​​the first partial edge-blended display area 215 may be adjusted to allow the projector 10 to allocate the first GUI display area 211 to display the first GUI image 213 . For example, the information indicating the second partial edge-blended display area 225 may include position information or size information indicating the second partial edge-blended display area 225. The position information may be information indicating the position at which the second partial edge-blended display area 225 is set in the second partial display area 33 of the screen 30. The position information may be defined by coordinate values ​​provided to divide the second partial display area 33 of the screen 30 into blocks of a predetermined size. The coordinate values ​​may be, for example, coordinate values ​​indicating an edge of the second partial edge-blended display area 225. The size information may include information about a horizontal length or a vertical length. The size information may include an area value of the second partial edge-blended display area 225.

[0151] In operation 635, the projector 10 may output a projected image (eg, as an optical signal such as a Figure 1 The first partial display image P1 is displayed in the first partial display area 31 allocated in the screen 30 based on the second layout. The projection image 13 may display the first GUI image 213 in the first GUI display area 211 and may display the first partial edge-blended image 217 in the first partial edge-blended display area 215. The projector 10 may generate, for example, the projection image 13 for displaying an edge-blended screen including the first GUI image 213, the first partial edge-blended image 217, and the second partial edge-blended image 227 on the screen 30 together with at least one external projector (e.g., the second projector 20) (see FIG. 1 ). Figure 2b ).

[0152] In operation 637, the projector 10 may monitor whether a signal is received from an external electronic device (eg, Figure 1 The layout update request information is received by the second projector 20 (e.g., the second projector 20). For example, the layout update request information may be received from another projector (e.g., the second projector 20) to jointly perform operations to provide edge blending services. For example, the layout update request information may be transmitted from the other projector 20 when an event occurs in the other projector 20 for changing the layout of the edge-blended image displayed on the screen 30.

[0153] According to an embodiment, the layout update request information may include instructions for other projectors 20 to display the fused image therein (eg, Figure 2c The second portion of the edge-fused image 227) has an area (eg, Figure 2cThe information indicating the second partial edge-blended display area 225 may include position information or size information indicating the second partial edge-blended display area 225. The position information may be information indicating the position where the second partial edge-blended display area 225 is set in the second partial display area 33 of the screen 30. The position information may be defined by coordinate values ​​provided to divide the second partial display area 33 of the screen 30 into blocks of predetermined sizes. The coordinate values ​​may be, for example, coordinate values ​​indicating the edges of the second partial edge-blended display area 225. The size information may include information about the horizontal length or the vertical length. The size information may include an area value of the second partial edge-blended display area 225.

[0154] According to an embodiment, the layout update request information may include instructions for other projectors 20 to display the fused image therein (eg, Figure 2c The second GUI image 223) of the region (eg, Figure 2c The information indicating the second GUI display area 221 may include information indicating the position or size of the second GUI display area 221. The position information may indicate the location of the second GUI display area 221 within the second partial display area 33 of the screen 30. The position information may be defined by coordinate values ​​that are provided to divide the second partial display area 33 of the screen 30 into blocks of predetermined sizes. The coordinate values ​​may, for example, indicate the edges of the second GUI display area 221. The size information may include information regarding the horizontal or vertical length. The size information may include the area value of the second GUI display area 221.

[0155] In operation 639, the projector 10 may determine a third layout based on the layout update request information. The layout update request information may include, for example, information indicating the second partial edge-blended display area 225. The layout update request information may include, for example, information indicating the second GUI display area 221. The layout update request information may include, for example, information indicating the second partial edge-blended display area 225 and the second GUI display area 221.

[0156] In operation 641, the projector 10 may output an edge-blended picture for display on the screen 30 based on the third layout (see FIG. Figure 2c ) of the projected image (e.g., Figure 1 The first projected image 13).

[0157] In operation 643, the projector 10 may monitor whether a GUI output termination request is received. The GUI output termination request may be monitored, for example, by whether a command for requesting termination of a setting program executed to adjust the configuration of the projector 10 is received. For example, the GUI output termination request may be monitored by a user interface (e.g., Figure 8 The user interface unit 820 of the projector 10 may input a command for requesting the termination of the execution of the setting program. This may be accomplished, for example, by a communication unit (eg, Figure 8 The communication unit 840) receives data from an external electronic device (e.g., Figure 1 The external electronic device may monitor for a command requesting termination of the setting program execution, such as a control message transmitted from a second projector 20 (e.g., a second projector 20). The external electronic device may be, for example, a portable terminal (e.g., a smartphone or a remote controller) operable by a user. If no GUI output termination request is received from the user, projector 10 may return to operation 637 and repeatedly perform subsequent operations.

[0158] If the GUI output termination request is received, the projector 10 may determine a fourth layout in operation 645. The fourth layout may define a layout in which the fused image (eg, Figure 2b The first portion of the edge-fused image 217) has an area (eg, Figure 2b The first edge fusion display area 215 of the first portion is set to an area on the screen 30 where the fused image is to be displayed (eg, Figure 1 For example, the fourth layout may define an arrangement structure in which the first GUI image 213 is no longer displayed in the first GUI display area 211 (see Figure 2d For example, when the first projector 10 and the second projector 20 participate in the edge blending service, the fourth layout may define a first partial edge blending display area 215 included in the first partial display area 31 of the screen 30 and a second partial edge blending display area 225 and a second GUI display area 221 included in the second partial display area 33 of the screen 30.

[0159] In operation 647, the projector 10 may send a message to at least one external projector (eg, Figure 1The second projector 20 (i.e., the external projector 20) sends a layout change request message requesting a change to the fourth layout. The layout change request message may include, for example, information indicating the second GUI display area 221 for displaying the second GUI image 223 and the second partial edge-blended display area 225 for displaying the second partial edge-blended image 227 in the second partial display area 33 allocated by the at least one external projector 20 on the screen 30. Assuming that the projector 10 no longer displays the first GUI image 213 in the first GUI display area 211, the second GUI display area 221 and the second partial edge-blended display area 225 may be updated in proportion to the first partial edge-blended display area 215, whose position or area has been adjusted.

[0160] For example, the information indicating the second GUI display area 221 may include position information or size information indicating the second GUI display area 221. The position information may be information indicating the position where the second GUI display area 221 is set in the second partial display area 33 of the screen 30. The position information may be defined by coordinate values ​​provided to divide the second partial display area 33 of the screen 30 into blocks of predetermined sizes. The coordinate values ​​may be, for example, coordinate values ​​indicating the edges of the second GUI display area 221. The size information may include information about the horizontal length or the vertical length. The size information may include an area value of the second GUI display area 221.

[0161] For example, the information indicating the second partial edge-blended display area 225 may include position information or size information indicating the second partial edge-blended display area 225. The position information may be information indicating the position where the second partial edge-blended display area 225 is arranged in the second partial display area 33 of the screen 30. The position information may be defined by coordinate values ​​provided to divide the second partial display area 33 of the screen 30 into blocks of predetermined sizes. The coordinate values ​​may be, for example, coordinate values ​​indicating the edges of the second partial edge-blended display area 225. The size information may include information about the horizontal length or the vertical length. The size information may include an area value of the second partial edge-blended display area 225.

[0162] In operation 649, the projector 10 may output a projection image (eg, such as a Figure 1 The projector 10 may generate, for example, a projection image 13 for displaying an edge-blended screen including the first partial edge-blended image 217, the second partial edge-blended image 227, and the second GUI image 223 on the screen 30 together with at least one external projector (e.g., the second projector 20). Figure 2d ).

[0163] In operation 651, the projector 10 may monitor whether a signal is received from an external electronic device (eg, Figure 1 For example, the layout update request information may be received from another projector (eg, the second projector 20) to perform operations together to provide an edge blending service.

[0164] For example, the layout update request information may be transmitted from the other projector 20 when an event for changing the layout of the edge-blended screen displayed on the screen 30 occurs in the other projector 20. The layout update request information may include, for example, an instruction to the projector 10 to display the fused image therein (e.g., Figure 2d The second portion of the edge-fused image 227) has an area (eg, Figure 2d The second portion of the edge blending display area 225) is displayed.

[0165] For example, the information indicating the second partial edge-blended display area 225 may include position information or size information indicating the second partial edge-blended display area 225. The position information may be information indicating the position at which the second partial edge-blended display area 225 is set in the second partial display area 33 of the screen 30. The position information may be defined by coordinate values ​​provided to divide the second partial display area 33 of the screen 30 into blocks of predetermined sizes. The coordinate values ​​may be, for example, coordinate values ​​indicating the edges of the second partial edge-blended display area 225. The size information may include information about the horizontal length or the vertical length. The size information may include an area value of the second partial edge-blended display area 225.

[0166] In operation 653, projector 10 may monitor whether a GUI output termination request is received from the user while outputting projection image 13 based on the second layout. The GUI output termination request may be monitored by, for example, whether a command for requesting termination of a setting program executed to adjust the configuration of projector 10 is received. For example, the command for requesting termination of execution of the setting program may be issued by the user through a user interface included in projector 10 (e.g., Figure 8 The user interface unit 820) can be input. For example, the communication unit (eg, Figure 8 The communication unit 840) receives data from an external electronic device (e.g., Figure 1The external electronic device may monitor for a command requesting termination of the setting program execution, such as a control message transmitted from a second projector 20 (e.g., a second projector 20). The external electronic device may be, for example, a portable terminal (e.g., a smartphone or a remote controller) operable by a user. If no GUI output termination request is received from the user, projector 10 may return to operation 637 and repeatedly perform subsequent operations.

[0167] If the layout update request information is received in operation 651 or the GUI output termination request is received in operation 653, the projector 10 may proceed to operation 655 to restore the layout to the first layout. Information about the first layout may be stored by the projector 10, for example. After changing to the first layout, the projector 10 may proceed to operation 615 to output a projection image (e.g., Figure 1 The first projection image 13 is used to display the edge-blended picture on the screen 30 (see Figure 2a ).

[0168] If termination of the edge blending service is requested when performing any one of operations 611 to 655, the projector 10 may terminate the edge blending service being executed and may perform a single operation (eg, Figure 3 A single operation 310).

[0169] Figure 7a and Figure 7b is a diagram showing a method for use with a projector (eg, Figure 1 The second projector 20) operates as an auxiliary device (e.g., Figure 5 However, the present disclosure is not limited thereto, and reference is made below to Figure 7a and Figure 7b In the description of FIG, the projector 10 may be an auxiliary device, and the external projector 20 may be a main device. Further, in the following description, detailed descriptions of operations overlapping with the above-described operations will be omitted.

[0170] refer to Figure 7a and Figure 7b In operation 711, the projector 10 may determine whether a request for activating an edge blending function for using an edge blending service is received. This may be accomplished, for example, by providing a user interface (eg, Figure 8 The projector 10 receives a request to activate the edge blending function based on information input from the user interface unit 820 (using the user interface unit 820). If the projector 10 receives a request to activate the edge blending function before the auxiliary operation subroutine is started, operation 711 can be omitted. The projector 10 can receive a request to activate the edge blending function from the external projector 20 as the main device.

[0171] The projector 10 may obtain or determine a first layout in operation 713. The first layout may define a display area of ​​the screen 30 (eg, Figure 1 The arrangement structure can allocate a display area to each projector participating in, for example, an edge blending service (see Figure 2a ). The projector 10 may receive information about the first layout from the external projector 20.

[0172] In operation 715, the projector 10 may output a projection image (eg, Figure 1 The second projection image 23 may be displayed as a second partial edge-blended image 227 in the second partial edge-blended display area 225 on the screen 30 .

[0173] In operation 717, the projector 10 may monitor whether a GUI output request is received. For example, the projector 10 may recognize that a GUI output request is received in response to receiving a command requesting execution of a setting program. The setting program may be, for example, a program for adjusting the settings of the edge blending function. For example, the setting program may be displayed through the user interface of the projector 10 (e.g., Figure 8 The user interface unit 820 of the projector 10 may be used to input a command for requesting execution of the setting program. Figure 8 The control message is received by the communication unit 840 (e.g., the external projector 20) and receives a command requesting the execution of the setting program. The control message may be sent by an external electronic device (e.g., an external projector 20).

[0175] In operation 721, projector 10 may obtain a second layout from the layout change request message, and may output a projection image (eg, Figure 1 The projection image 23 may display a second partial edge-blended image 227 in the updated second partial edge-blended display area 225 on the screen 30. The image displayed on the screen 30 by outputting the second projection image 23 may be as follows. Figure 2b shown.

[0176] Projector 10 may monitor whether a GUI output request is received in operation 723 and may monitor whether a layout change request message is received in operation 725. If neither a GUI output request nor a layout change request message is received, projector 10 may proceed to operation 721.

[0177] If the layout change request message is received, the projector 10 may restore the layout to the first layout in operation 727. Information about the first layout may be stored, for example, by the projector 10. After changing to the first layout, the projector 10 may proceed to operation 715 to output a projection image (e.g., Figure 1 The second projected image 23 is used to display the edge-blended image on the screen 30 (see Figure 2a ).

[0178] If a GUI output request is received, the projector 10 may allocate a display area (eg, Figure 2c The second GUI display area 221 of the display area 221) outputs a GUI image to be displayed by itself (for example, Figure 2c The second GUI image 223 is displayed. The second GUI display area 221 may be allocated by the external projector 20 as the primary device. In this case, the projector 10 may omit operation 729.

[0179] In operation 731, the projector 10 may send a layout update request message to the external projector 20. The layout update request message may include layout update request information. For example, the layout update request information may be information for allocating the second GUI display area 221 to display the second GUI image 223 requested to be output, or for updating the second partial edge-blended display area 225.

For example, the layout change request information may include information regarding the third layout. The GUI output termination request may be monitored, for example, by receiving a command requesting termination of a function based on the GUI screen currently being displayed by projector 10.

[0193] If neither the layout change request message nor the GUI output termination request is received, the projector 10 may proceed to operation 755 to output a projection image based on the fourth layout toward the screen 30 (eg, Figure 1 The second projected image 23 is used to display the edge-blended image on the screen 30 (see Figure 2d ).

[0194] If a GUI output termination request is received, the projector 10 may restore the layout to the first layout in operation 747. Information about the first layout may be stored, for example, by the projector 10. After changing to the first layout, the projector 10 may proceed to operation 715 to output a projection image (e.g., Figure 1 The second projected image 23 is used to display the edge-blended image on the screen 30 (see Figure 2a ).

[0195] If a layout change request message is received while the fourth layout is applied, projector 10 may obtain a third layout from the layout change request message and output an edge-blended picture for display on screen 30 based on the obtained third layout toward screen 30 in operation 591 (see FIG. Figure 2c ) of the projected image (e.g., Figure 1 The second projected image 23).

[0196] In operation 761, the projector 10 may monitor whether a GUI output termination request is received. The GUI output termination request may be monitored by, for example, whether a command requesting termination of a function according to the GUI screen being displayed by the projector 10 is received.

[0197] If the GUI termination request is not received, the projector 10 may continuously output the second projection image 23 based on the third layout in operation 759. If the GUI termination request is received, the projector 10 may proceed to operation 741 to perform restoration to the second layout. Figure 2b 7. A screen displayed on the screen 30 through the second layout is shown in FIG. After returning to the second layout, the projector 10 may perform operation 721.
