The disclosure relates to a projection device supporting an edge blending function and a method for controlling the projection device.
Projection devices may be divided into analog projection devices that may provide visual information using a medium, e.g., a film, and digital projection devices that may provide visual information using digital signals. A representative example of the digital projection device is the beam projector (hereinafter, simply referred to as a “projector”). The projector may be classified as a display device. The projector may be implemented as a cathode ray tube (CRT) projector, a liquid crystal display (LCD) projector, or a digital light processing (DLP) projector depending on how to generate light.
The projector is used mainly to display input multimedia content as it is, but as wired/wireless communication networks develop, the projector may be connected to an electronic device, e.g., a digital television (TV), to assist the electronic device.
The projector may be an electronic device that may project slides, photos on a transparent sheet, pictures or text, or images on the screen through a lens. The projector is also called a projection device. The projector may convert file images or video data into an optical image and project or radiate the optical image. The optical image projected or radiated by the projector may be shown on the screen.
The size of the screen displayed by the projector may be limited by the supported resolution, contrast ratio, or brightness. Edge blending may be a method for overcoming such screen size limit.
Edge blending may function to adjust the brightness or color of the blending area which is an overlapping area between the images projected by different projectors to enlarge the screen without resolution, contrast ratio, or brightness loss using at least two projectors.

Referring to
According to an embodiment, the display system 1 may include at least two image projection devices or a screen 30. For example, the display system 1 may include a first image projection device (hereinafter, referred to as a “first projector 10”) and a second image projection device (hereinafter, referred to as a “second projector 20”). The first projector 10 may be a first beam projector. The second projector 20 may be a second beam projector.
The first projector 10 may include a first light output unit 11. The first projector 10 may project the first projection image 13 toward the screen 30 through the first light output unit 11. The projection may mean, e.g., that a 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.
The second projector 20 may include a second light output unit 21. The second projector 20 may project the second projection image 23 toward the screen 30 through the second light output unit 21. The projection may mean, e.g., that a beam corresponding to the second projection image 23 is radiated toward the screen 30. The second projection image 23 may allow a second partial display image P2 to appear in a second partial display area 33 provided on the screen 30.
The edge blending image displayed on the screen 30 by the first projection image 13 output by the first projector 10 and the second projection image 23 output by the second projector 20 may include a blended image. The blending image may be an image displayed in a blending area 35 in which the first partial display area 31 and the second partial display area 33 overlap each other in the display area of the screen 30. To that end, the first projector 10 and the second projector 20 may allow an optical image corresponding to a blending image to be displayed in the blending area 35 to have characteristics such as different resolution or contrast from an optical image corresponding to an image to be displayed in another area. This is to prevent the sharpness of the blending image from being lowered because the first projection image 13 and the second projection image 23 are overlaid and displayed.
The first projection image 13 output by the first projector 10 may display a target image in a partial area (e.g., the first partial display area 31) or the entire area 130 of the screen 30. For example, in the case of a single operation (e.g., the single operation 310 of
The first projector 10 may establish a communication link with the second projector 20 based on at least one communication scheme 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.
The second projection image 23 output by the second projector 20 may display a target image in a partial area (e.g., the second partial display area 33) or the entire area 130 of the screen 30. For example, in the case of a single operation (e.g., the single operation 310 of
The second projector 20 may establish a communication link with the first projector 10 based on at least one communication scheme 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.
For example, the first projector 10 may function as a primary device or a main device. For example, the second projector 20 may function as a secondary device or a sub device. The first projector 10 may perform main functions as a primary device for displaying the edge blending screen 130 according to the edge blending function on the screen 30. The main functions performed by the primary device may include, e.g., a function of determining an image to be projected by itself (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.
According to an example, if the edge blending function is activated, the first projector 10 along with the second projector 20 may perform the edge blending operation for displaying the edge blending 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 20 from the edge blending image. For example, when the first projector 10 operates as a primary device, the first projector 10 may transfer 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.
The first projector 10 may output a first projection image 13 corresponding to the first partial display image to the screen 30. The first projection image 13 output by the first projector 10 may allow the first partial display image, which is the first blending image, to be displayed in the first partial display area 31 of the screen 30.
The second projector 20 may output a second projection image 23 corresponding to the second partial display image to the screen 30. The second projection image 23 output by the second projector 20 may allow the second partial display image, which is the second blending image, to be displayed in the second partial display area 33 of the screen 30.
According to an embodiment, the first partial display area 31 and the second partial display area 33 may commonly include an overlapping area (e.g., the blending area 35 of
An example of the edge blending screen displayed on the screen 30 by the above-described operations of the first projector 10 and the second projector 20 is illustrated in
According to an embodiment, if a GUI output request is generated after the edge blending function is activated, the first projector 10 may generate a virtual screen to provide a surplus area by reducing an area to display the first partial display image and an area to display the second partial display image together with the second projector 20. The first projector 10 may allocate the provided surplus area as a display area for displaying a GUI image. In this case, the first projector 10 may transfer, to the second projector 20, information about the area in which the first partial display image and/or the second partial display image having the adjusted position or size are to be displayed.
The first projector 10 may generate an image in which the first partial display image is positioned in the adjusted area and the GUI image is disposed in a designated position or size in the surplus area, and may output the image to the screen 30 through the first light output unit 11. The first projection image 13 output by the first projector 10 may allow the GUI image and the first partial display image, which is the first blending image, to be displayed in the first partial display area 31 of the edge blending screen by the changed position and/or size.
The second projector 20 may output the second projection image 23 to the screen 30 so that the second partial display image is displayed in the adjusted area. The second projection image 23 output by the second projector 20 may allow the second partial display image, which is the second blending image, to be displayed in the second partial display area 33 of the edge blending screen by the changed position and/or size.
An example of the edge blending screen displayed on the screen 30 by the above-described operations of the first projector 10 and the second projector 20 is illustrated in
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 may generate a virtual screen to provide a surplus area by reducing an area to display the first partial display image and an area to display the second partial display image together with the second projector 20. The first projector 10 may allocate the provided surplus area as a display area for displaying a GUI image. In this case, the first projector 10 may transfer, to the second projector 20, information about the area in which the second partial display image and/or the GUI image having the adjusted position or size are to be displayed.
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. The first projection image 13 output by the first projector 10 may allow the first partial display image, which is the first blending image, to be displayed in the first partial display area 31 of the screen 30 by the changed position and/or size.
The second projector 20 may output the 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 designated position or size in the surplus area. The second projection image 23 output by the second projector 20 may allow the GUI image and the second partial display image, which is the second blending image, to be displayed in the second partial display area 33 of the screen 30 by the changed position and/or size.

According to an embodiment, when GUI output requests are sequentially or simultaneously generated 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 an area in which the first partial display image and the second partial display image are to be displayed, thereby providing a surplus area. The first projector 10 may allocate a first GUI display area for displaying a first GUI image to a first surplus area provided in the first partial display area 31. The first projector 10 may allocate a second GUI display area for displaying a second GUI image to a second surplus area provided in the second partial display area 33. In this case, the first projector 10 may transfer, to the second projector 20, information about the area in which the second partial display image and/or the second GUI image having the adjusted position or size are to be displayed.
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 at a designated position or size in the first surplus area. The first projection image 13 output by the first projector 10 may allow the first GUI image and the first partial display image, which is the first blending image, to be displayed in the first partial display area 31 of the screen 30 by the changed position and/or size.
The second projector 20 may output the 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 designated position or size in the surplus area. The second projection image 23 output by the second projector 20 may allow the second GUI image and the second partial display image, which is the second blending image, to be displayed in the second partial display area 33 of the screen 30 by the changed position and/or size.

In this case, the processor 810 may control the communicator 840 to transfer, to the second projector 20, information about the area in which the second partial display image and/or the GUI image having the adjusted position or size are to be displayed.
The processor 810 may control the image emitter 830 to output the first projection image 13 to the screen 30 so that the first partial display image is displayed in the adjusted area. The first projection image 13 output from the image emitter 830 under the control of the processor 810 may allow the first partial display image, which is the first blending image, to be displayed in the first partial display area 31 of the screen 30 by the changed position and/or size.
According to the above-described operation, the processor 810 may control the image emitter 830 to project the optical image based on the layout of the virtual screen shown in
According to an embodiment, when GUI output requests are sequentially or simultaneously generated from the first projector 10 and the second projector 20 after the edge blending function is activated, the processor 810 may generate a virtual screen to reduce an area in which the first partial display image and the second partial display image are to be displayed, thereby providing a surplus area. The processor 810 may allocate a first GUI display area for displaying a first GUI image to a first surplus area provided in the first partial display area 31. The processor 810 may allocate a second GUI display area for displaying a second GUI image to a second surplus area provided in the second partial display area 33. In this case, the processor 810 may control the communicator 840 to transfer, to the second projector 20, information about the area in which the second partial display image and/or the second GUI image having the adjusted position or size are to be displayed.
The processor 810 may control the image emitter 830 to 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 at a designated position or size in the first surplus area. The first projection image 13 output from the image emitter 830 under the control of the processor 810 may allow the first GUI image and the first partial display image, which is the first blending image, to be displayed in the first partial display area 31 of the screen 30 by the changed position and/or size.
According to the above-described operation, the processor 810 may control the image emitter 830 to project the optical image based on the layout of the virtual screen shown in

According to an embodiment of the disclosure, the electronic devices are not limited to those described above.
It should be appreciated that various embodiments of the disclosure and the terms used therein are not intended to limit the technological features set forth herein to particular embodiments and include various changes, equivalents, or replacements for a corresponding embodiment. With regard to the description of the drawings, similar reference numerals may be used to refer to similar or related elements. It is to be understood that a singular form of a noun corresponding to an item may include one or more of the things, unless the relevant context clearly indicates otherwise. As used herein, each of such phrases as “A or B,” “at least one of A and B,” “at least one of A or B,” “A, B, or C,” “at least one of A, B, and C,” and “at least one of A, B, or C,” may include all possible combinations of the items enumerated together in a corresponding one of the phrases. As used herein, such terms as “1st” and “2nd,” or “first” and “second” may be used to simply distinguish a corresponding component from another, and does not limit the components in other aspect (e.g., importance or order). It is to be understood that if an element (e.g., a first element) is referred to, with or without the term “operatively” or “communicatively”, as “coupled with,” “coupled to,” “connected with,” or “connected to” another element (e.g., a second element), it means that the element may be coupled with the other element directly (e.g., wiredly), wirelessly, or via a third element.
As used herein, the term “module” may include a unit implemented in hardware, software, or firmware, and may interchangeably be used with other terms, for example, “logic,” “logic block,” “part,” or “circuitry”. A module may be a single integral component, or a minimum unit or part thereof, adapted to perform one or more functions. For example, according to an embodiment, the module may be implemented in a form of an application-specific integrated circuit (ASIC).
Various embodiments as set forth herein may be implemented as software (e.g., the program) including one or more instructions that are stored in a storage medium (e.g., memory) that is readable by a machine (e.g., the display system 1). For example, a processor (e.g., the processor 810) of the machine (e.g., the first projector 10) may invoke at least one of the one or more instructions stored in the storage medium, and execute it, with or without using one or more other components under the control of the processor. This allows the machine to be operated to perform at least one function according to the at least one instruction invoked. The one or more instructions may include a code generated by a complier or a code executable by an interpreter. The storage medium readable by the machine may be provided in the form of a non-transitory storage medium. Wherein, the term “non-transitory” simply means that the storage medium is a tangible device, and does not include a signal (e.g., an electromagnetic wave), but this term does not differentiate between where data is semi-permanently stored in the storage medium and where the data is temporarily stored in the storage medium.
According to an embodiment, a method according to various embodiments of the disclosure may be included and provided in a computer program product. The computer program products may be traded as commodities between sellers and buyers. The computer program product may be distributed in the form of a machine-readable storage medium (e.g., compact disc read only memory (CD-ROM)), or be distributed (e.g., downloaded or uploaded) online via an application store (e.g., Play Store™), or between two user devices (e.g., smart phones) directly. If distributed online, at least part of the computer program product may be temporarily generated or at least temporarily stored in the machine-readable storage medium, such as memory of the manufacturer's server, a server of the application store, or a relay server.
