In one embodiment, the first image may be an image provided to the user, and may be an image corresponding to the user's field of view. For example, the first image may be an image corresponding to the surrounding environment viewed by the user through the eyes.

[0070] In one embodiment, it is assumed that the first camera sensor (210) is a camera sensor corresponding to the user's left eye, and the second camera sensor (220) is a camera sensor corresponding to the user's right eye. The processor (260) can obtain a first image corresponding to the first viewpoint by obtaining an image corresponding to the left eye through the first camera sensor (210) and an image corresponding to the right eye through the second camera sensor (220). In this case, the first image corresponding to the first viewpoint can include an image corresponding to the left eye and an image corresponding to the right eye, respectively.

[0071] In one embodiment, the processor (260) may acquire an image from either the first camera sensor (210) or the second camera sensor (220). In this case, the first image corresponding to the first viewpoint may include only one of the image corresponding to the left eye or the image corresponding to the right eye. In one embodiment, only one of the first camera sensor (210) or the second camera sensor (220) may perform an operation of acquiring (or outputting) an image, but is not limited thereto. Each of the first camera sensor (210) and the second camera sensor (220) may perform an image acquisition operation, and the processor (260) may acquire only one of them.

[0072] In one embodiment, the processor (260) may acquire a second image corresponding to the first viewpoint through at least one third camera sensor (230). In one embodiment, the second image may be an image different from the first image. In one embodiment, when the second angle of view corresponding to at least one third camera sensor (230) is relatively larger than the first angles of view corresponding to the first camera sensor (210) and the second camera sensor (220), the second image may be an image corresponding to a relatively wider field of view than the first image. In one embodiment, the second image may be utilized as a reference image for predicting an image corresponding to the user's field of view. This will be described in detail with reference to FIGS. 4A to 4D.

[0073] In one embodiment, the processor (260) may use sensing data corresponding to the user's movement, together with a first image corresponding to a first angle of view (e.g., the user's field of view), a second image corresponding to a second angle of view (e.g., a reference image), to predict an image corresponding to the user's field of view at a point in time after a specified period of time has elapsed from the present. In one embodiment, the processor (260) may identify a third image corresponding to a second point in time after the first point in time based on the first image corresponding to the first point in time, the second image corresponding to the first point in time, and sensing data acquired through an acceleration sensor.

[0074] In one embodiment, the second point of view may be a point of view after the first point of view and may be a point of view before a third point of view at which an image is re-acquired through the first camera sensor (210) (and / or the second camera sensor (220)). In one embodiment, the third image may be an image of a future point of view corresponding to the user's field of view. For example, the third image may be a predicted image corresponding to the surrounding environment viewed by the user at a point of time after a specified period of time has elapsed from the present. The third image may be an image corresponding to the first angle of view in one embodiment. In one embodiment, the third image may be an image corresponding to the user's field of view and may include an image corresponding to the left eye and an image corresponding to the right eye, respectively.

[0075] In one embodiment, the processor (260) may use the learned artificial intelligence model to identify a third image corresponding to the second viewpoint. In one embodiment, the memory may include a first artificial intelligence model that outputs a third image corresponding to the second viewpoint. In one embodiment, the first artificial intelligence model may be implemented as a generative artificial intelligence model. In one embodiment, the first artificial intelligence model may be a model learned to output an image of a second viewpoint corresponding to the first angle of view when an image of a first viewpoint (e.g., a first image corresponding to a first angle of view and a first image corresponding to a second angle of view) and sensing data corresponding to a user's movement are input. In one embodiment, the processor (260) may input the first image corresponding to the first viewpoint, the second image corresponding to the first viewpoint, and the sensing data into the first artificial intelligence model. In one embodiment, the first artificial intelligence model may output a third image corresponding to the second viewpoint, and the processor (260) may identify the third image corresponding to the second viewpoint based on the output.

[0076] In one embodiment, the first artificial intelligence model may be a pre-learned model, but is not limited thereto, and of course, it may be learned in real time based on data input while the head mounting device (200) is operating.

[0077] In one embodiment, the sensing data may be six degrees of freedom (6DoF) acceleration information corresponding to a camera sensor included in the head-mounted device (200). In one embodiment, the processor (260) may also identify a third image corresponding to a second time point using a moving average value of the sensing data over a specified time period.

[0078] In one embodiment, the processor (260) may input information about characteristic parameters (e.g., at least one of a camera angle of view, a relative position between a plurality of cameras, and a camera shooting direction) corresponding to each of the first camera sensor (210), the second camera sensor (220), and at least one third camera sensor (230) into the first artificial intelligence model to identify a third image corresponding to the second time point. For example, the processor (260) may input information about sensing data and characteristic parameters, along with the first image of the first time point and the second image of the first time point, into the first artificial intelligence model to identify the third image corresponding to the second time point.

[0079] In one embodiment, the first artificial intelligence model may have a configuration at least partially identical or similar to the configuration of the generative artificial intelligence system illustrated in FIG. 10. In one embodiment, the first artificial intelligence model may be implemented as a generative adversarial network (GAN) model that generates images based on input data.

[0080] FIG. 3 is a flowchart for explaining an operation method of a head mounting device (e.g., the head mounting device (200) of FIG. 2) according to one embodiment.

[0081] Hereinafter, a method of operating a head-mounted device according to various embodiments will be described in detail. According to various embodiments, the operations performed by the head-mounted device described below may be executed by a processor (e.g., processor (260) of FIG. 2) including at least one processing circuitry of the head-mounted device. According to one embodiment, the operations performed by the head-mounted device may be stored in a memory (e.g., memory (250) of FIG. 2) and, when executed, executed by instructions that cause the processor (260) to operate. In the embodiments below, each operation may be performed sequentially, but is not necessarily performed sequentially. For example, the order of each operation may be changed, and at least two operations may be performed in parallel. Depending on the implementation, certain operations may be omitted.

[0082] Referring to FIG. 3, according to one embodiment, in operation 301, the head mounted device may acquire a first image (e.g., the first image of FIG. 2) corresponding to a first viewpoint through at least one of a first camera sensor (e.g., the first camera sensor (210) of FIG. 2) corresponding to a first angle of view and a second camera sensor (e.g., the second camera sensor (220) of FIG. 2) corresponding to the first angle of view. In one embodiment, the first image may be an image provided to a user, and may be an image corresponding to a field of view (or, the first angle of view) of the user. In one embodiment, the first image acquired through the first camera sensor and / or the second camera sensor may be an image corresponding to a surrounding environment viewed through the eyes of the user.

[0083] In one embodiment, when the first camera sensor is a camera sensor corresponding to the left eye, the head mounted device can obtain an image corresponding to the left eye from the first camera sensor as the first image. In one embodiment, when the second camera sensor is a camera sensor corresponding to the right eye, the head mounted device can obtain an image corresponding to the right eye from the second camera sensor as the first image. In one embodiment, the head mounted device can also obtain images (an image corresponding to the left eye and an image corresponding to the right eye) obtained from each of the first camera sensor and the second camera sensor as the first image.

[0084] According to one embodiment, in operation 303, the head-mounted device may acquire a second image (e.g., the second image of FIG. 2) corresponding to the first viewpoint through at least one third camera sensor (e.g., at least one third camera sensor (230) of FIG. 2) corresponding to the second viewpoint. In one embodiment, the second image may be an image corresponding to a different viewpoint from the first image. For example, when the second viewpoint is relatively larger than the first viewpoint, the second image may be an image corresponding to a relatively wider field of view than the first image. In one embodiment, when a plurality of third camera sensors are implemented, a plurality of second images corresponding to the first viewpoint may be provided. This will be described in detail with reference to FIGS. 4A and 4B.

[0085] In one embodiment, in operation 305, the head-mounted device can identify a third image corresponding to a second time point after the first time point based on a first image corresponding to the acquired first time point, a second image corresponding to the acquired first time point, and sensing data (e.g., sensing data of FIG. 2) acquired through an acceleration sensor (e.g., acceleration sensor (240) of FIG. 2).

[0086] In one embodiment, the head-mounted device may include an acceleration sensor, and may obtain sensing data corresponding to the user's movement through the acceleration sensor. In one embodiment, the head-mounted device may use the obtained sensing data, a first image corresponding to a first time point, and a second image corresponding to the first time point, to predict a third image corresponding to a second time point after the first time point. The third image may be an image corresponding to the first angle of view, in one embodiment. In one embodiment, the third image is an image corresponding to the user's field of view, and may include an image corresponding to the left eye and an image corresponding to the right eye, respectively.

[0087] FIGS. 4A to 4D are drawings for explaining a camera sensor and generated images according to one embodiment.

[0088] Referring to FIGS. 4A to 4D , according to one embodiment, a head mounting device (400, e.g., head mounting device (200) of FIG. 2 ) may include a plurality of camera sensors (401, 402, 403, 404, 410, and 420).

[0089] In one embodiment, the head mounted device (400) may include a first camera sensor (410, e.g., the first camera sensor (210) of FIG. 2) and a second camera sensor (420, e.g., the second camera sensor (220) of FIG. 2). In one embodiment, the first camera sensor (410) may be a camera sensor corresponding to the left eye of the user (40). In one embodiment, the first camera sensor (410) may be a camera sensor corresponding to a first angle of view (e.g., the first angle of view of FIG. 2) and may acquire an image corresponding to the left eye of the user (40). In one embodiment, the second camera sensor (420) may be a camera sensor corresponding to the right eye of the user (40). In one embodiment, the second camera sensor (420) may be a camera sensor corresponding to a first angle of view and may acquire an image corresponding to the right eye of the user (40). In one embodiment, the first image (e.g., the first image of FIG. 2) may include at least one of an image corresponding to the left eye of the user (40) and an image corresponding to the right eye of the user (40).

[0090] In one embodiment, the head mounted device (400) may include at least one third camera sensor (401, 402, 403, and 404). In one embodiment, the at least one third camera sensor (401, 402, 403, and 404) may be disposed at a designated location within the head mounted device (400), but is not limited thereto, and of course, may be disposed at a different location than the location illustrated in FIG. 4A. In one embodiment, although four third camera sensors are depicted as being disposed in the head mounted device (400) in FIG. 4A, the present invention is not limited thereto, and of course, a different number of third camera sensors may be disposed in the head mounted device (400).

[0091] In one embodiment, at least one third camera sensor (401, 402, 403, and 404) can acquire a second image (e.g., the second image of FIG. 2) corresponding to a different angle of view than the first image. In one embodiment, referring to FIG. 4B, the first camera sensor (410), the second camera sensor (420), and the at least one third camera sensor (401, 402, 403, and 404) can have different angles of view. In one embodiment, the first angle of view (43) corresponding to the first camera sensor (410) and the second camera sensor (420) can be less than the second angle of view (41) (e.g., the second angle of view of FIG. 2) corresponding to the at least one third camera sensor (401, 402, 403, and 404). Accordingly, the second image acquired through at least one third camera sensor (401, 402, 403, and 404) may be an image having a relatively wide field of view compared to the first image acquired through the first camera sensor (410) or the second camera sensor (420).

[0092] In one embodiment, as shown in FIGS. 4A and 4B, the first camera sensor (410) may be positioned at a position corresponding to the left eye of the user (40), and the second camera sensor (420) may be positioned at a position corresponding to the right eye of the user (40), but is not limited thereto. It is to be understood that the first camera sensor (410) may be positioned at a position corresponding to the right eye of the user (40), and the second camera sensor (420) may be positioned at a position corresponding to the left eye of the user (40).

[0093] In one embodiment, the second angle of view (41) corresponding to at least one of the third camera sensors (401, 402, 403, and 404) may be relatively larger than the first angle of view (43) corresponding to the first camera sensor (410) and the second camera sensor (420). In one embodiment, referring to FIG. 4C, among the fields of view (430), the fields of view (432) corresponding to the second image acquired through at least one of the third camera sensors (401, 402, 403, and 404) may be relatively wider than the fields of view (431) corresponding to the first image. Here, the fields of view (432) corresponding to the second image may be fields of view corresponding to images acquired from each of the at least one of the third camera sensors (401, 402, 403, and 404).

[0094] In one embodiment, the head mounted device (400) may generate a third image (e.g., the third image of FIG. 2) of a second viewpoint using movement information of the user (40). For example, when sensing data (e.g., sensing data of FIG. 2) corresponding to a movement of the user (40) raising his / her head is acquired, the head mounted device (400) may, based on the sensing data, identify an image of a field of view (433) corresponding to the movement of the user (40) among a field of view (432) corresponding to the second image, and identify this as a third image of the second viewpoint. In this case, the third image may include at least one of an image of the second viewpoint corresponding to the left eye and an image of the second viewpoint corresponding to the right eye.

[0095] In one embodiment, as illustrated in FIG. 4D, it is assumed that at least one third camera sensor (401, 402, 403, and 404) is positioned at a designated location of the head mounting device (400). Referring to FIG. 4D, each of the second images (401-1, 402-1, 403-1, and 404-1) acquired through each of the third camera sensors may be images corresponding to different field of view ranges from each of the image (410-1) acquired through the first camera sensor (410) and the image (420-1) acquired through the second camera sensor (420). For example, in the case of the second image (401-1) acquired through the third camera sensor (401) located relatively at the upper left of the head-mounted device (400), the image may have a relatively wide field of view (or, imaging range) for the left and upper regions compared to the image (410-1) acquired from the first camera sensor (410) corresponding to the left eye. Accordingly, as illustrated in FIG. 4C, the field of view (432) corresponding to the second images (401-1, 402-1, 403-1, and 404-1) may be relatively wider than the field of view (431) corresponding to the first image (e.g., at least one of the image (410-1) and the image (420-1)).

[0096] In one embodiment, if at least one of the third camera sensors (401, 402, 403 and 404) is implemented as an RGB camera, the second image may be a color image, but is not limited thereto, and at least one of the third camera sensors (401, 402, 403 and 404) may be implemented as a black and white camera, in which case the second image may be a black and white image.

[0097] In one embodiment, the head mounted device (400) may provide the identified third image to the user (40) when a third image corresponding to the second time point is identified. In one embodiment, the head mounted device (400) may further include a display (e.g., the display module (160) of FIG. 1). In one embodiment, the head mounted device (400) may display the third image corresponding to the identified second time point through the display. For example, after the first image corresponding to the first time point is displayed through the display, when the third image corresponding to the second time point is identified, the head mounted device (400) may display the third image through the display after the display of the first image is finished.

[0098] FIG. 5A is a flowchart illustrating a method for identifying an image corresponding to a second point in time (e.g., the second point in FIG. 2 ) according to one embodiment. FIG. 5B is a diagram illustrating a method for identifying an image corresponding to a second point in time (e.g., the second point in FIG. 2 ) according to one embodiment.

[0099] In the following examples, the operations may be performed sequentially, but are not necessarily sequential. For example, the order of the operations may be changed, and at least two operations may be performed in parallel. Depending on the implementation, certain operations may be omitted.

[0100] Referring to FIGS. 5A and 5B , in one embodiment, at operation 501, a head mounted device (e.g., head mounted device (200) of FIG. 2 ) may acquire at least one of a left-eye image corresponding to a first viewpoint (e.g., the first viewpoint of FIG. 2 ) and a right-eye image corresponding to the first viewpoint, via at least one of a first camera sensor (e.g., the first camera sensor (210) of FIG. 2 ) and a second camera sensor (e.g., the second camera sensor (220) of FIG. 2 ). In one embodiment, the first image may include at least one of a left-eye image corresponding to the first camera sensor and a right-eye image corresponding to the second camera sensor.

[0101] In one embodiment, the left-eye image corresponding to the first viewpoint may be an image corresponding to the left eye of the user (e.g., the user (40) of FIG. 4). In one embodiment, when the first camera sensor is implemented as a camera sensor corresponding to the left eye, the head-mounted device can obtain an image (or left-eye image) corresponding to the user's left eye through the first camera sensor. In one embodiment, when the second camera sensor is implemented as a camera sensor corresponding to the right eye, the head-mounted device can obtain an image (or right-eye image) corresponding to the user's right eye through the second camera sensor. However, the present invention is not limited thereto, and it is of course possible for the first camera sensor to correspond to the user's right eye and the second camera sensor to correspond to the user's left eye.

[0102] In one embodiment, the head mounted device may acquire images from either the first camera sensor or the second camera sensor, but is not limited thereto, and in one embodiment, the head mounted device may acquire images from each of the first camera sensor and the second camera sensor.

[0103] In one embodiment, in operation 503, the head-mounted device inputs at least one acquired image into a first artificial intelligence model (e.g., the first artificial intelligence model of FIG. 2) to identify a left-eye image corresponding to a second time point (e.g., the second time point of FIG. 2) and a right-eye image corresponding to the second time point. That is, even if the head-mounted device does not input the left-eye image corresponding to the first time point and the right-eye image corresponding to the first time point to the first artificial intelligence model, the head-mounted device can identify the left-eye image corresponding to the second time point and the right-eye image corresponding to the second time point.

[0104] In one embodiment, when either the left-eye image or the right-eye image (510, or the first image) corresponding to the first time point is acquired, the head-mounted device can input the acquired first image (510) into the first artificial intelligence model to confirm a third image (540) corresponding to the second time point. In one embodiment, the third image (540) may each include a left-eye image corresponding to the second time point and a right-eye image corresponding to the second time point, and the third image (540) may be an image of a plurality of frames. In one embodiment, the head-mounted device can display the confirmed third image (540) after the first image (510) corresponding to the first time point is provided.

[0105] In one embodiment, the head-mounted device can alternately acquire a left-eye image corresponding to the first camera sensor and a right-eye image corresponding to the second camera sensor. For example, when the head-mounted device acquires a left-eye image as a first image (510) corresponding to a first time point, the head-mounted device can acquire a right-eye image as a fourth image (520) corresponding to a third time point through the second camera sensor after a specified time has elapsed. After the fourth image (520) is acquired, the head-mounted device can acquire a left-eye image as a sixth image (530) corresponding to a fifth time point through the first camera sensor after a specified time has elapsed.

[0106] In one embodiment, the head-mounted device can input the acquired fourth image (520) into the first artificial intelligence model to confirm the fifth image (550) corresponding to the fourth point of view. In one embodiment, the fifth image (550) may include a left-eye image corresponding to the fourth point of view and a right-eye image corresponding to the fourth point of view, and the fifth image (550) may be an image of a plurality of frames.

[0107] In one embodiment, the head mounted device may end display of the third image (540) and display the fourth image (520) when the fourth image (520) is acquired after displaying a portion of the identified third image (540). In one embodiment, the head mounted device may end display of the identified fifth image (550) when display of the fourth image (520) is terminated. However, the present invention is not limited thereto, and in one embodiment, when display of the fourth image (520) is terminated, the head mounted device may generate a new image based on the remaining portion of the identified third image (540) and the identified fifth image (550). This will be described later.

[0108] In one embodiment, the head-mounted device may acquire the first image through only one of the first camera sensor and the second camera sensor. For example, the head-mounted device may acquire the first image through only the first camera sensor and input the acquired first image into the first artificial intelligence model to acquire the third image. However, the present invention is not limited thereto, and the head-mounted device may acquire the first image through only the second camera sensor and input the acquired second image into the first artificial intelligence model to acquire the third image. In one embodiment, when the first image is acquired through only one of the first camera sensor and the second camera sensor, the image acquired through the other one may be used as a reference image.

[0109] According to the above example, the head-mounted device can not only predict an image corresponding to the user's field of view using the left-eye and right-eye images respectively acquired via the camera sensor, but can also predict an image corresponding to the user's field of view using only one of the acquired left-eye and right-eye images. Accordingly, the power consumption and generation time for generating the predicted image can be reduced.

[0110] According to the example described above, since the predicted images acquired through the AI ​​model are provided alongside the images acquired through the camera sensor, the user can be provided with images at a relatively high frame rate (FPS) compared to images acquired through a conventional camera sensor. Since the head-mounted device can provide highly responsive pass-through images, user satisfaction is enhanced.

[0111] According to the above-described example, the head-mounted device can generate a prediction image using only one of the plurality of pass-through cameras (e.g., the first camera sensor and the second camera sensor), and thus can provide the user with an image having relatively low latency compared to the case where the prediction image is generated using each of the plurality of pass-through cameras.

[0112] FIG. 6 is a flowchart illustrating a method of post-processing a confirmed image according to one embodiment.

[0113] In the following examples, the operations may be performed sequentially, but are not necessarily sequential. For example, the order of the operations may be changed, and at least two operations may be performed in parallel. Depending on the implementation, certain operations may be omitted.

[0114] Referring to FIG. 6, in one embodiment, at operation 601, a head-mounted device (e.g., head-mounted device (200) of FIG. 2) may input a left-eye image corresponding to the identified second point in time (e.g., left-eye image of FIG. 5) and a right-eye image corresponding to the identified second point in time (e.g., right-eye image of FIG. 5) into a second artificial intelligence model.

[0115] In one embodiment, the memory (e.g., memory (250) of FIG. 2) may further include a second artificial intelligence model. In one embodiment, the second artificial intelligence model may be a supervised-learning artificial intelligence model. In one embodiment, the second artificial intelligence model may be a model trained to output, when a confirmed third image (e.g., a left-eye image corresponding to the second viewpoint and a right-eye image corresponding to the confirmed second viewpoint) is input, a post-processed left-eye image corresponding to the second viewpoint and a post-processed right-eye image corresponding to the second viewpoint. In one embodiment, the post-processed left-eye image and the post-processed right-eye image may be images in which a viewpoint corresponding to the images is corrected.

[0116] In one embodiment, assume that a left-eye image is acquired through a first camera sensor (e.g., the first camera sensor (210) of FIG. 2) and a right-eye image is acquired through a second camera sensor (e.g., the second camera sensor (220) of FIG. 2). If the left-eye image and the right-eye image are acquired through different camera sensors, the head-mounted device can perform image correction based on the view point (or point of view (POV)) corresponding to each camera sensor, thereby improving the accuracy of the image provided to the user.

[0117] In one embodiment, the viewpoint may be obtained through an extrinsic parameter corresponding to each camera sensor. In one embodiment, the extrinsic parameter may be information about the position of the camera sensor in a 3D (dimensional) space and information about the direction the camera sensor is looking, and the viewpoint may be information obtained based on the extrinsic parameter. In one embodiment, the intrinsic parameters of the first camera sensor and the second camera sensor may be the same. The intrinsic parameters of the camera sensor may include information about how much the image panel moves, how much it is enlarged, and how much it is tilted. In one embodiment, when the intrinsic parameters of the first camera sensor and the second camera sensor are the same as described above, the head mounted device may perform correction on the image based on the viewpoint associated with the extrinsic parameter, thereby obtaining a highly accurate image.

[0118] In one embodiment, the head-mounted device may obtain a post-processed image by comparing an image acquired through a camera sensor with an image acquired through a first artificial intelligence model. In one embodiment, the second artificial intelligence model may be supervised and learned by comparing an image acquired through a camera sensor with an image identified through the first artificial intelligence model. In one embodiment, a third image identified through the first artificial intelligence model, together with a first image acquired through at least one of the first camera sensor and the second camera sensor, may be input as learning data to the second artificial intelligence model.

[0119] For example, a left-eye image corresponding to a first viewpoint, acquired through a first camera sensor, and a right-eye image corresponding to the first viewpoint, verified through a first artificial intelligence model, may be input as learning data to a second artificial intelligence model. In this case, a left-eye image corresponding to the first viewpoint, acquired through a first camera sensor, and a right-eye image acquired through a second camera sensor (e.g., the second camera sensor (220) of FIG. 2) may be input together as labels.

[0120] In one embodiment, in operation 603, the head-mounted device can identify a post-processed left-eye image corresponding to the second time point and a post-processed right-eye image corresponding to the second time point. In one embodiment, the head-mounted device can identify the image output from the second artificial intelligence model as a post-processed left-eye image corresponding to the second time point and a post-processed right-eye image corresponding to the second time point.

[0121] FIG. 7a is a flowchart illustrating a method for displaying an image according to one embodiment. FIG. 7b is a diagram illustrating a method for displaying an image according to one embodiment.

[0122] In the following examples, the operations may be performed sequentially, but are not necessarily sequential. For example, the order of the operations may be changed, and at least two operations may be performed in parallel. Depending on the implementation, certain operations may be omitted.

[0123] Referring to FIGS. 7A and 7B , according to one embodiment, at operation 701, a head mounted device (e.g., head mounted device (200) of FIG. 2 ) may determine whether a fourth image (730) corresponding to a third point in time after a second point in time (e.g., the second point in time of FIG. 2 ) has been acquired after at least a portion of a third image (740, e.g., the third image of FIG. 2 ) has been displayed.

[0124] In one embodiment, when a first image (720, for example, at least one of a left-eye image corresponding to the first time point (e.g., the left-eye image of FIG. 5A) and a right-eye image corresponding to the first time point (e.g., the right-eye image of FIG. 5A)) corresponding to the first time point is acquired, the head mounted device can identify a third image (740) corresponding to the second time point. The head mounted device can display the identified third image (740) through a display module (e.g., the display module (160) of FIG. 1). In one embodiment, the third image (740) can include images of a plurality of frames. In one embodiment, the head mounted device can identify whether a fourth image (730) corresponding to the third time point is acquired after at least a portion of the identified third image (740) is displayed. In one embodiment, the head-mounted device may acquire a fourth image (730) corresponding to a third viewpoint through at least one of a first camera sensor (e.g., the first camera sensor (210) of FIG. 2) or a second camera sensor (e.g., the second camera sensor (220) of FIG. 2).

[0125] In one embodiment, in operation 703, the head mounted device may terminate display of the third image (740) and display the fourth image (730) through the display based on the acquisition of the fourth image (730). In one embodiment, if the fourth image (730) is acquired after at least a portion of the third image (740) has been displayed, the head mounted device may display the fourth image (730) through the display and not display the remaining portion (750) of the third image (740) that is not displayed.

[0126] In one embodiment, a third image (740) acquired through a first artificial intelligence model (e.g., the first artificial intelligence model of FIG. 2) may be temporarily stored in a designated space (e.g., a frame buffer) within a head-mounted device. When a fourth image (730) is acquired after at least a portion of the third image (740) is displayed, the head-mounted device may delete the remaining portion (750) stored in the designated space and temporarily store the fourth image (730) in the designated space.

[0127] According to the example described above, even while the AI ​​model is providing the predicted image to the user, if a new image is acquired through the camera sensor, the head-mounted device can terminate the provision of the predicted image and provide the user with the image acquired through the camera sensor. This can improve user satisfaction.

[0128] FIG. 8a is a flowchart illustrating a method for displaying an image according to one embodiment. FIG. 8b is a diagram illustrating a method for displaying an image according to one embodiment.

[0129] In the following examples, the operations may be performed sequentially, but are not necessarily sequential. For example, the order of the operations may be changed, and at least two operations may be performed in parallel. Depending on the implementation, certain operations may be omitted.

[0130] Referring to FIGS. 8A and 8B, in one embodiment, at operation 801, a head-mounted device (e.g., head-mounted device (200) of FIG. 2) can determine whether a fourth image (e.g., fourth image (730) of FIG. 7B) corresponding to a third point in time after the second point in time has been acquired after a third image (810, e.g., third image of FIG. 2) is displayed.

[0131] For example, let's assume that the number of frames of the third image acquired through the first artificial intelligence model is 6. The head-mounted device can display the third image (810) corresponding to the second time point through a display module (e.g., the display module (160) of FIG. 1). The head-mounted device can determine whether the fourth image is acquired until the display of the third image (810) is completed. However, the present invention is not limited thereto, and in one embodiment, the head-mounted device can determine whether the fourth image is acquired until the display of a part of the third image (810) is completed.

[0132] In one embodiment, at operation 803, the head mounted device may acquire updated sensing data (e.g., the sensing data of FIG. 2) via an acceleration sensor (e.g., the acceleration sensor (240) of FIG. 2) based on the fourth image not being acquired. In one embodiment, the head mounted device may acquire the updated sensing data when it is determined that the fourth image is not acquired after the third image (810) is displayed. For example, the head mounted device may acquire the sensing data at the time when it is determined that the fourth image is not acquired. However, the present invention is not limited thereto.

[0133] In one embodiment, at operation 805, the head mounted device may input a first image (e.g., the first image of FIG. 2), a second image corresponding to a first time point (e.g., the second image of FIG. 2), and updated sensing data into a first artificial intelligence model (e.g., the first artificial intelligence model of FIG. 2), thereby additionally generating a third image corresponding to the second time point.

[0134] In one embodiment, the head-mounted device can input updated sensing data, along with the first image and the second image used to generate the third image (810), into the first artificial intelligence model to confirm the added third image (820).

[0135] In one embodiment, the head mounted device may display the added third image (820) through the display after the display of the existing third image (810) is completed. In one embodiment, after a portion of the added third image (820) is displayed, if it is confirmed that a fourth image is acquired, the head mounted device may delete the remainder of the added third image (820) stored in a designated storage space (e.g., the frame buffer of FIGS. 7A and 7B) and temporarily store the fourth image (830). The head mounted device may display the stored fourth image (830) through the display.

[0136] According to the example described above, since 10 additional images are generated compared to the images acquired through the camera sensor, an image with an FPS 10 times larger than before can be provided to the user.

[0137] FIG. 9 is a flowchart illustrating a method of displaying an image according to one embodiment.

[0138] In the following examples, the operations may be performed sequentially, but are not necessarily sequential. For example, the order of the operations may be changed, and at least two operations may be performed in parallel. Depending on the implementation, certain operations may be omitted.

[0139] Referring to FIG. 9, according to one embodiment, a head-mounted device (e.g., the head-mounted device (200) of FIG. 2) may, in operation 901, determine whether a fourth image (e.g., the fourth image of FIGS. 7A and 7B) corresponding to a third point in time after the second point in time has been acquired after at least a portion of a third image (e.g., the third image of FIG. 2) has been displayed.

[0140] In one embodiment, when a first image corresponding to a first time point (e.g., a left-eye image corresponding to the first time point (e.g., a left-eye image of FIG. 5A) and a right-eye image corresponding to the first time point (e.g., a right-eye image of FIG. 5A)) is acquired, the head mounted device can identify a third image corresponding to a second time point. The head mounted device can display the identified third image through a display module (e.g., the display module (160) of FIG. 1). In one embodiment, the third image may include images of a plurality of frames. In one embodiment, the head mounted device can identify whether a fourth image corresponding to the third time point is acquired after at least a portion of the identified third image is displayed. In one embodiment, the head mounted device can acquire the fourth image corresponding to the third time point through at least one of a first camera sensor (e.g., the first camera sensor (210) of FIG. 2) or a second camera sensor (e.g., the second camera sensor (220) of FIG. 2).

[0141] In one embodiment, the head-mounted device, based on the acquisition of the fourth image in operation 903, may acquire a fifth image corresponding to the fourth time point using the remaining portion of the third image and the fourth image. In one embodiment, the head-mounted device may blend the acquired fourth image with the remaining portion of the third image that is not yet displayed using a designated algorithm. In one embodiment, the head-mounted device may identify the blended image as the fifth image.

[0142] According to one embodiment, the head mounted device may display the acquired fifth image via a display at operation 905.

[0143] According to the example described above, the head-mounted device can obtain and provide to the user an image blended with a predicted image obtained through an artificial intelligence model and an image obtained through a camera sensor. This allows for an image with improved accuracy to be provided to the user.

[0144] FIG. 10 is a diagram for explaining a generative artificial intelligence system (1000) according to one embodiment.

[0145] According to one embodiment, a user query / response interface (1010) can receive user input. The user input may be in the form of natural language, images, and / or videos, but is not limited thereto. Furthermore, context information may also be transmitted when the user input is transmitted. The context information may include various additional information at the time of the user input. For example, the additional information may include information about the application currently being used by the user or information about the user's location. Furthermore, the user input may be in a form that combines the aforementioned natural language, images, sounds, and context information. Furthermore, the user input may also be in a non-natural language form, such as selecting a menu. The user query / response interface (1010) can output the results of the generative artificial intelligence system to the user. The output may be in the form of natural language or specific content, and may also be provided in the form of an action requested by the user. The user query / response interface (1010) can output the results of the generative artificial intelligence system to the user. The output can be in natural language form, in the form of specific content, or in the form of an action requested by the user.

[0146] The AI ​​framework (1040) can receive user input and coordinate and control each component necessary to perform the user's intention based on the user's query.

[0147] User input received from the user query / response interface (1010) can be transmitted to a prompt design component (1041). The prompt design component (1041) can be used to generate prompts suitable for inputting user input into a large language model (LLM) or a large multimodal model (LMM). The prompt design component (1041) can be an AI component that uses a machine learning algorithm or a neural network to develop better prompts over time. The prompt design component (1041) can access a knowledge component including user preference data, a prompt library, and prompt examples based on the user input to generate prompts and transmit the generated prompts to the LLM or LMM.

[0148] The API / Plug-in management component (1042) can communicate with external information when there is a request for additional information when passing user input as input to a generative model. The API / Plug-in management component (1042) can establish a channel for communicating with the outside of the AI ​​Interface through the API, and can enable access to various data sources (e.g., knowledge repositories (1020)) through the established channel. In addition, the API / Plug-in management component (1042) can request the application / service component (1030) through the API for an action that ultimately performs the user input, rather than an intermediate result, when the action needs to be performed in the application or service. Information obtained from the outside can be used to generate a prompt in the prompt design component (1041) together with the user input, or can be passed as input to the generative model.

[0149] The output modification component (also called a refiner component) (1043) can fine-tune the output results from the generative model. For example, the output modification component (1043) can verify that the content generated through the LLM and / or LMM is not irrelevant, does not contain biased content, or does not contain harmful content. In addition, the output modification component (1043) can determine to what extent it matches the result desired by the user and, if additional processing is necessary, can proceed with the process. The output modification component (1043) can additionally configure and provide the user with hints to avoid unwanted output.

[0150] A generative AI model (1060) may generally refer to an artificial intelligence neural network that creates new types of data based on user input information. The generative AI model (1060) may include an image-generating model and / or a language-generating model. Representative models for generating images include a generative adversarial network (GAN) and a variational auto encoder (VAE), and examples include a VAE and a Diffusion-based generative model that uses a Transformer structure. A language-generating model is a model trained to statistically output the most appropriate output based on input values, and representative examples include models such as CHAT-GPT 3 and CHAT-GPT 4. In addition, there are also LMMs (large multimodal models) that can recognize various types of data input, such as text, images, and voice, and generate new data corresponding to them.

When a component (e.g., a first component) is referred to as "coupled" or "connected" to another component (e.g., a second component), with or without the terms "functionally" or "communicatively," it means that the component can be connected to the other component directly (e.g., wired), wirelessly, or through a third component.

[0216] The term "module" used in various embodiments of this document may include a unit implemented in hardware, software, or firmware, and may be used interchangeably with terms such as logic, logic block, component, or circuit. A module may be an integral component, or a minimum unit or part of such a component that performs one or more functions. For example, according to one embodiment, a module may be implemented in the form of an application-specific integrated circuit (ASIC).

[0217] Various embodiments of the present document may be implemented as software (e.g., a program (140)) including one or more instructions stored in a storage medium (e.g., an internal memory (136) or an external memory (138)) readable by a machine (e.g., an electronic device (101)). For example, a processor (e.g., a processor (120)) of the machine (e.g., an electronic device (101)) may call at least one instruction among the one or more instructions stored from the storage medium and execute it. This enables the machine to operate to perform at least one function according to the at least one called instruction. The one or more instructions may include code generated by a compiler or code executable by an interpreter. The machine-readable storage medium may be provided in the form of a non-transitory storage medium. Here, 'non-transitory' simply means that the storage medium is a tangible device and does not contain signals (e.g., electromagnetic waves), and the term does not distinguish between cases where data is stored semi-permanently or temporarily on the storage medium.

[0218] According to one embodiment, the method according to various embodiments disclosed in this document may be provided as included in a computer program product. The computer program product may be traded as a product between a seller and a buyer. 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 may be distributed online (e.g., downloaded or uploaded) through an application store (e.g., Play Store™) or directly between two user devices (e.g., smart phones). In the case of online distribution, at least a portion of the computer program product may be temporarily stored or temporarily generated in a machine-readable storage medium, such as the memory of a manufacturer's server, an application store's server, or an intermediary server.

[0219] According to various embodiments, each component (e.g., a module or a program) of the above-described components may include one or more entities, and some of the entities may be separated and arranged in other components. According to various embodiments, one or more components or operations of the aforementioned components may be omitted, or one or more other components or operations may be added. Alternatively or additionally, a plurality of components (e.g., a module or a program) may be integrated into a single component. In such a case, the integrated component may perform one or more functions of each of the plurality of components identically or similarly to those performed by the corresponding component among the plurality of components prior to the integration. According to various embodiments, the operations performed by a module, program, or other component may be executed sequentially, in parallel, iteratively, or heuristically, or one or more of the operations may be executed in a different order, omitted, or one or more other operations may be added.
