For example, the display device (100) can analyze the contrast between the background and an object.

[0085] In one embodiment, the display device (100) can apply a virtual aiming point based on at least one of the position of at least one object, the motion of the at least one object, or the background characteristics.

[0087] According to an example, in operation 330, the display device (100) can set a region of interest (ROI) including the virtual aiming point (VAP). Hereinafter, operation 330 of the display device (100) will be described in detail with reference to FIGS. 7 and 8.

[0088] FIG. 7 is an exemplary diagram showing an operation of a display device (100) according to one embodiment of the present disclosure to set a region of interest (ROI).

[0089] Referring to Figure 7, a region of interest (ROI) is an area of ​​high importance within an input image, which may be determined based on a virtual aiming point (VAP). For example, the region of interest (ROI) may have a predetermined shape centered around the virtual aiming point (VAP) and may include part or all of a target.

[0090] The display device (100) can set a region of interest (ROI) having a predetermined size and shape. For example, the size and shape of the region of interest (ROI) can be determined based on a user's settings. For example, the size and shape of the region of interest (ROI) can be automatically determined based on the image characteristics of the input image.

[0091] The display device (100) can adjust the size of the region of interest (ROI) based on at least one of the size, importance, or location of the target within the input image. For example, the display device (100) can increase the size of the region of interest (ROI) in proportion to the size of the target.

[0094] Referring to FIG. 8, the display device (100) can change the region of interest (ROI) based on a change in the virtual aiming point (VAP). For example, the display device (100) can change the position of the virtual aiming point (VAP) based on a change in the position of the target within the input image. For example, the display device (100) can change the region of interest (ROI) based on (e.g., in response to) a change in the position of the virtual aiming point (VAP).

[0095] In one embodiment, when the position of the virtual aiming point (VAP) changes, the display device (100) can change at least one of the position of the region of interest (ROI), the size of the region of interest (ROI), or the shape of the region of interest (ROI). For example, when the position of a target in an input image changes, a first virtual aiming point (VAP1) corresponding to the position of the target before the change may change to a second virtual aiming point (VAP2) corresponding to the position of the target after the change. For example, when the first virtual aiming point (VAP1) changes to the second virtual aiming point (VAP2), the display device (100) can change the position of the region of interest (ROI) from the position of the first region of interest (ROI1) to the position of the second region of interest (ROI2).

[0096] For example, in operation 340, the display device (100) can adjust the size or effect of the first image (Image1) corresponding to the region of interest (ROI). Hereinafter, operation 340 of the display device (100) will be described in detail with reference to FIGS. 9A to 9C.

[0097] FIGS. 9A to 9C are exemplary diagrams showing an operation of a display device (100) according to one embodiment of the present disclosure to adjust the size or effect of a first image (Image1).

[0098] Referring to FIGS. 9A to 9C, the display device (100) can adjust the size or effect of the first image (Image1) corresponding to the region of interest (ROI). For example, the display device (100) can perform at least one of enlargement, reduction, sharpening, blurring, contrast adjustment, color adjustment, or distortion filter application to the first image (Image1).

[0099] As shown in FIG. 9A, the display device (100) can perform at least one of zooming in and zooming out on a first image (e.g., Image1a). The display device (100) can zoom in on an image within a region of interest (ROI) set around a virtual aiming point (VAP) to increase visibility of the target. For example, when aiming at an enemy character in an FPS game, the user can easily recognize details of the enemy using the zoomed-in first image (e.g., Image1b). For example, when a user needs to secure a wider field of view in an FPS game, the user can easily find the enemy character using the zoomed-out first image (Image1).

[0100] As shown in FIG. 9B, the display device (100) can perform at least one of blurring, contrast adjustment, or color adjustment on the first image (e.g., Image1a). The display device (100) can apply various image filters to more clearly express the image within the region of interest (ROI). For example, the display device (100) can apply a blurring filter to blur the background outside the region of interest (ROI), thereby focusing the user's attention on the virtual aiming point (VAP). For example, the display device (100) can increase the contrast of the first image (e.g., Image1c) within the region of interest (ROI) through contrast adjustment, thereby making the target more visible. For example, the display device (100) can use a color adjustment filter to emphasize or convert a specific color, thereby making the target within the input image clearly distinguishable from the background.

[0101] As shown in FIG. 9c, the display device (100) can apply a distortion filter to the first image (e.g., Image1a). For example, the display device (100) can provide a specific visual effect by applying the distortion filter to a region of interest (ROI) around a virtual aiming point (VAP). For example, the display device (100) can apply a fish-eye lens effect to the first image (e.g., Image1a). In the case of the first image (e.g., Image1d) to which the fish-eye lens effect is applied, as the center of the region of interest (ROI) is enlarged and the periphery is distorted, a target corresponding to the center of the region of interest (ROI) can be further emphasized. For example, the display device (100) can apply a perspective distortion filter to the first image (Image1). When the perspective distortion filter is applied to the first image (Image1), the user's aiming convenience can be increased as the visual depth in a specific direction of the region of interest (ROI) is emphasized.

[0102] In one example, in operation 350, the display device (100) can generate a second image (Image2) by synthesizing the input image and the first image (Image1). In one example, in operation 360, the display device (100) can display the second image (Image2) through the display. Hereinafter, operations 350 and 360 of the display device (100) will be described in detail with reference to FIGS. 10a and 10b.

[0103] FIGS. 10A and 10B are exemplary diagrams showing a second image (Image2) generated by a display device (100) according to one embodiment of the present disclosure.

[0104] Referring to FIGS. 10A and 10B , the display device (100) can generate a second image (Image2) by synthesizing an input image and a first image (Image1), and display the second image (Image2). For example, the display device (100) can determine the position and size of the first image (Image1) to be synthesized on the input image. For example, the display device (100) can synthesize the first image (Image1) on a predetermined area of ​​the input image in a graphic overlay manner. For example, the display device (100) can use an alpha blending technique to smoothly synthesize the first image (Image1) and the input image. The display device (100) can generate a second image (Image2) in which the first image (Image1) is synthesized on the input image.

[0105] The display device (100) can display a second image (Image2). For example, the display device (100) can adjust at least one of the resolution, brightness, or contrast of the second image (Image2) obtained by synthesizing the first image (Image1) onto the input image. For example, as shown in FIG. 10a, the second image (Image2a) may be an image obtained by synthesizing the first image (Image1) corresponding to a rectangular region of interest (ROI) onto the input image in an enlarged manner using a graphic overlay. For example, as shown in FIG. 10b, the second image (Image2b) may be an image obtained by synthesizing the first image (Image1) corresponding to a circular region of interest (ROI) onto the input image in an enlarged manner using a graphic overlay.

[0106] In one embodiment, the display device (100) can apply a virtual aiming point (VAP) to an input image and display an image with the size or effect of a region of interest (ROI) centered around the virtual aiming point (VAP) adjusted. The display device (100) can enhance the immersion and user satisfaction with video content by increasing the aiming accuracy of game play.

[0107] In one embodiment, the display device (100) detects a virtual aiming point (VAP) embedded in an input image, thereby preventing the redundant application of the virtual aiming point (VAP) and changing the size or effect of the adjusted image based on the movement direction or movement speed of the input image. The display device (100) can provide a flexible screen configuration suitable for the display environment and provide image content optimized for game play in real time.

[0108] FIG. 11 is a flowchart showing an operation of changing the size or effect of a first image (Image1) by a display device (100) according to one embodiment of the present disclosure.

[0109] Referring to FIG. 11, the display device (100) can detect at least one of a movement direction and a movement speed of the input image (operation 1110), and change the size or the effect of the first image (Image1) based on at least one of the movement direction and the movement speed (operation 1120).

[0110] For example, in operation 1110, the display device (100) can detect at least one of the movement direction and movement speed of the input image. The display device (100) can extract consecutive frames and recognize screen changes for each frame. For example, the display device (100) can identify the location and shape of a key object in each frame.

[0111] The display device (100) can determine the direction of movement of an input image by analyzing the direction of movement of an object. For example, the display device (100) can determine the direction of movement of the input image as forward or backward. For example, the display device (100) can determine the direction of movement of the input image as horizontal or vertical.

[0112] The display device (100) can calculate the movement distance by calculating the change in the position of an object in consecutive frames. For example, the display device (100) can calculate the movement speed of an input image based on the movement distance per unit time (e.g., number of pixels).

[0113] For example, in operation 1120, the display device (100) may change (or adjust) the size or the effect of the first image (Image1) based on at least one of the movement direction and the movement speed. The display device (100) may cause the size or effect of the first image to be changed (or adjusted) based on the movement speed of the input image based on whether the input image moves forward or backward. The display device (100) may cause the size or effect of the first image to be changed (or adjusted) based on the movement speed based on whether the input image moves in a horizontal direction or a vertical direction. Hereinafter, operation 1110 of the display device (100) will be exemplarily described with reference to FIGS. 12 and 13.

[0114] FIG. 12 is an exemplary diagram showing an operation of a display device (100) according to one embodiment of the present disclosure to change the size of a first image (Image1) according to a movement direction and movement speed.

[0115] Referring to FIG. 12, the display device (100) can change the size of the first image (Image1) based on the movement speed of the input image when the input image moves forward or backward. For example, the movement direction of the input image may be the Z-axis direction (e.g., D1).

[0116] For example, when the input image moves forward (e.g., D1), the display device (100) can reduce the size of the first image (Image1) because the distance from the target becomes closer. When the input image moves forward (e.g., D1), the display device (100) can change the enlarged first image (Image1) into the original image. For example, when the input image moves backward, the display device (100) can enlarge the size of the first image (Image1) because the distance from the target becomes farther. For example, the display device (100) can reduce or enlarge the size of the first image (Image1) based on (e.g., proportionally) the movement speed.

[0117] FIG. 13 is an exemplary diagram showing an operation of a display device (100) according to one embodiment of the present disclosure to change the effect of a first image (Image1) according to a movement direction and movement speed.

[0118] Referring to FIG. 13, the display device (100) can adjust the effect of the first image (e.g., Image1e) when the input image moves in the horizontal or vertical direction. For example, the movement direction of the input image can be the X-axis direction (e.g., D2) or the Y-axis direction.

[0119] For example, when an input image moves in a horizontal or vertical direction, the display device (100) can enlarge the size of the first image (e.g., Image1e) because the visibility of the target may decrease as the screen moves. The display device (100) can enlarge the first image (e.g., Image1e) at a set magnification. The display device (100) can adjust the image quality of the first image (e.g., Image1f) so that the enlarged first image (e.g., Image1f) can be displayed clearly. For example, when an input image moves in a horizontal or vertical direction, the display device (100) can adjust (or change) the effect of the first image (e.g., Image1e) to obtain an emphasized first image (e.g., Image1f). For example, when an input image moves in a horizontal direction (e.g., D2), the display device (100) can emphasize the movement direction by adjusting the contrast or color. For example, the display device (100) can enhance the effect of the first image (e.g., Image1f) in proportion to the movement speed. For example, when the input image moves in the vertical direction, the display device (100) can smoothly express the movement by adjusting the blurring or sharpening effect.

[0120] FIGS. 14A to 14C are drawings showing various ways in which a display device (100) according to one embodiment of the present disclosure displays a first image (Image1).

[0121] Referring to FIGS. 14A to 14C , the display device (100) of the present disclosure can display a first image (Image1) corresponding to a region of interest (ROI) at various locations. For example, the display device (100) can display the first image (Image1) in a non-display area (nda). For example, the display device (100) can display the first image (Image1) in a picture-in-picture (PIP) manner.

[0122] For example, as shown in FIG. 14a, the display device (100) may include a non-display area (nda) on the left or right side of the display area, depending on the difference between the supported resolution of the display device (100) and the resolution of the input image. The display device (100) may display the first image (Image1) on the non-display area (nda) on the left or right side where no image content is displayed.

[0123] For example, as shown in FIG. 14b, the display device (100) may include a non-display area (nda) at the top or bottom of the display area, depending on the difference between the supported resolution of the display device (100) and the resolution of the input image. The display device (100) may display the first image (Image1) in the non-display area (nda) at the top or bottom where no image content is displayed.

[0124] For example, as shown in FIG. 14c, the display device (100) can output a sub-screen displaying a first image (Image1) within a main screen displaying an input image in a pip manner. The display device (100) can change the position and size of the sub-screen displaying the first image (Image1). For example, the display device (100) can change the position or adjust the size of the sub-screen displaying the first image (Image1) based on user settings.

[0125] FIG. 15 is a flowchart illustrating the operation of a display device (100) according to one embodiment of the present disclosure when an embedded virtual aiming point (EVAP) exists in an input image.

[0126] Referring to FIG. 15, the display device (100) detects an embedded virtual aim point (EVAP) included in the input image (operation 1510), and based on the detection of the embedded virtual aim point (EVAP), disables the redundant application of the virtual aim point (VAP) to the input image (operation 1520), sets the region of interest (ROI) including the embedded virtual aim point (EVAP) (operation 1530), and adjusts the size or effect of a third image (Image3) corresponding to the region of interest (ROI) (operation 1540).

[0127] According to an example, in operations 1510 and 1520, the display device (100) may detect an embedded virtual aiming point (EVAP) included in an input image, and based on the detection of the embedded virtual aiming point (EVAP), may disable the redundant application of the virtual aiming point (VAP) to the input image. Hereinafter, operations 1510 and 1520 of the display device (100) will be exemplarily described with reference to FIG. 16.

[0128] FIG. 16 is an exemplary diagram showing an input image of a display device (100) according to one embodiment of the present disclosure.

[0129] Referring to FIG. 16, the display device (100) can analyze the image characteristics of an input image. The display device (100) can extract individual frames from the input image. For example, the display device (100) can analyze the image characteristics of the input image based on the extracted individual frames. Based on the image characteristics, the display device (100) can identify an embedded virtual aiming point (EVAP) included in the input image.

[0130] The display device (100) may disable the redundant application of the virtual aiming point (VAP) to the input image based on the detection of the built-in virtual aiming point (EVAP). For example, the display device (100) may set a flag to prevent the redundant application of the virtual aiming point (VAP) to the input image, thereby preventing the application of an additional virtual aiming point (VAP) to an input image including the built-in virtual aiming point (EVAP).

[0131] For example, in operations 1530 and 1540, the display device (100) may set a region of interest (ROI) including an embedded virtual aiming point (EVAP) and adjust the size or effect of a third image (Image3) corresponding to the region of interest (ROI). Hereinafter, operations 1530 and 1540 of the display device (100) will be exemplarily described with reference to FIG. 17.

[0132] FIG. 17 is an exemplary diagram showing an operation of a display device (100) according to one embodiment of the present disclosure to adjust the size or effect of a third image (Image3).

[0133] Referring to FIG. 17, the display device (100) can set a region of interest (ROI) by utilizing an embedded virtual aiming point (EVAP). For example, the display device (100) can adjust the size of the region of interest (ROI) based on at least one of the size, importance, or location of the target within the input image. For example, the display device (100) can adjust the shape of the region of interest (ROI) based on the shape of the target or a user's settings.

[0134] The display device (100) can adjust the size or effect of the third image (Image3) corresponding to the region of interest (ROI). For example, the display device (100) can perform at least one of enlargement, reduction, sharpening, blurring, contrast adjustment, color adjustment, or distortion filter application to the third image (Image3).

[0135] The display device (100) can perform at least one of magnification and reduction on the third image (Image3). The display device (100) can magnify an image within a region of interest (ROI) set around a virtual aiming point (VAP), thereby increasing the visibility of the target. For example, when aiming at an enemy character in an FPS game, a user can easily recognize details of the enemy using the magnified third image (Image3).

[0136] The display device (100) can perform at least one of blurring, contrast adjustment, or color adjustment on the third image (Image3). The display device (100) can apply various image filters to more clearly express the image within the region of interest (ROI). For example, the display device (100) can apply a blurring filter to blur the background outside the region of interest (ROI), thereby focusing the user's attention on the virtual aiming point (VAP). For example, the display device (100) can increase the contrast of the image within the region of interest (ROI) through contrast adjustment, thereby making the target more visible.

[0137] FIG. 18 is a flowchart showing an operation according to a type of control signal of a display device (100) according to one embodiment of the present disclosure, and FIGS. 19a and 19b are drawings showing an operation performed according to a type of control signal of a display device (100) according to one embodiment of the present disclosure.

[0138] Referring to FIG. 18, the display device (100) receives a control signal from the control device (3) (operation 1810), determines whether the control signal is a first control signal unrelated to adjusting the size or the effect of the first image (Image1) corresponding to the region of interest (ROI), or a second control signal that adjusts the size or the effect of the first image (Image1) (operation 1820), and if the control signal is the first control signal, transmits the first control signal to the server (2) (operation 1830), and if the control signal is the second control signal, adjusts the size or the effect of the first image (Image1) based on the second control signal (operation 1840).

[0139] According to an example, in operation 1810, the display device (100) can receive a control signal from the control device (3). As shown in FIGS. 19A and 19B , the control device (3) can output a user input to the display device (100). The control device (3) can be connected to the display device (100) via a wireless communication network. For example, the control device (3) can be located within a predetermined distance from the display device (100) and communicate with the display device (100) via a BLE (Bluetooth Low Energy) communication network. For example, the control device (3) can generate a user input based on a user action and transmit the user input to the display device (100) via the BLE communication network.

[0140] For example, the control device (3) may be, but is not limited to, a remote control (3a), a game controller (3b), a keyboard (3c), a smartphone, a tablet PC, a PC, a smart TV, a mobile phone, a PDA (personal digital assistant), a laptop, a media player, a micro server (2), a GPS (global positioning system) device, an e-book reader, a digital broadcasting terminal, a navigation device, a kiosk, an MP3 player, a digital camera, and other mobile or non-mobile computing devices. In addition, the control device (3) may be a wearable device having a communication function and a data processing function.

[0141] According to an example, in operation 1820, the display device (100) can determine whether the control signal received from the control device (3) is a first control signal or a second control signal. For example, the display device (100) can determine whether the control signal is a first control signal that is unrelated to adjusting the size or the effect of the first image (Image1) corresponding to the region of interest (ROI), or a second control signal that adjusts the size or the effect of the first image (Image1). For example, the first control signal may be a control signal that attacks a target in an input image. For example, the second control signal may be a control signal that changes the effect of the first image (Image1) corresponding to the region of interest (ROI).

[0142] According to an example, in operation 1830, the display device (100) may transmit the first control signal to the server (2) if the control signal is the first control signal. For example, as shown in FIG. 19A, the display device (100) may identify the first control signal (cont1) and request the server (2) to perform a control operation corresponding to the first control signal (cont1).

[0143] For example, in operation 1840, the display device (100) may adjust the size or the effect of the first image (Image1) based on the second control signal, if the control signal is the second control signal. For example, as shown in FIG. 19b, the display device (100) may identify the second control signal (cont2) and perform an image adjustment operation corresponding to the second control signal (cont2). Here, the display device (100) may not transmit the second control signal (cont2) to the server (2).

[0144] In one embodiment, a display device (100) and a display method using the same can apply a virtual aiming point (VAP) to an input image and display an image in which the size or effect of a region of interest (ROI) centered on the virtual aiming point (VAP) is adjusted. The display device (100) and a display method using the same can enhance the immersion and user satisfaction with video content by increasing the aiming accuracy of game play.

[0145] In one embodiment, the display device (100) and the display method using the same can detect a virtual aiming point (VAP) embedded in an input image, thereby preventing the redundant application of the virtual aiming point (VAP), and can change the size or effect of an image adjusted based on the movement direction or movement speed of the input image. The display device (100) and the display method using the same can provide a flexible screen configuration suitable for the display environment, and can provide image content optimized for game play in real time.
