    Abstract: A wallpaper system presents a first wallpaper image of a wallpaper video to a user and receives, via a user input device, one or both of: (i) a spatial user input selection, and (ii) a time user input selection from the user to apply to the wallpaper video. In response to detecting one or both of: (i) the spatial user input selection, and (ii) the time user input selection, the wallpaper system determines one or both of: (i) a respective spatial movement parameter within a wallpaper video associated with the spatial user input selection, and (ii) a respective time coordinate within the wallpaper video associated with the time user input selection. Wallpaper system presents, via the image display, a second wallpaper image associated with one or both of: (i) the respective spatial movement parameter, and (ii) the respective time coordinate.

    Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for varied depth determination using stereo vision and phase detection auto focus (PDAF). Computer stereo vision (stereo vision) is used to extract three-dimensional information from digital images. To utilize stereo vison, two optical sensors are displaced horizontally from one another and used to capture images depicting two differing views of a real-world environment from two different vantage points. The relative depth of the objects captured in the images is determined using triangulation by comparing the relative positions of the objects in the two images. For example, the relative positions of matching objects (e.g., features) identified in the captured images are used along with the known orientation of the optical sensors (e.g., distance between the optical sensors, vantage points the optical sensors) to estimate the depth of the objects.

    CPC classification number: H04N25/57

    Abstract: A method for increasing a dynamic range of a dual-pixel image sensor is described. The method includes detecting an intensity level of a full pixel from a plurality of pixels of an optical sensor, one or more full pixels of the plurality of pixels includes at least two sub-pixels, detecting an intensity level of one or more sub-pixels, detecting that the intensity level of the full pixel of the optical sensor has reached a saturation level of the full pixel, and in response to detecting that the intensity level of the full pixel of the optical sensor has reached the saturation level of the full pixel, computing an extrapolated intensity level of the full pixel based on the intensity level of the one or more sub-pixels.

    Abstract: Methods and system for creating and managing personalized fonts. Personalized fonts are created by applying personalization parameters to a base font using a style application method or module such as a neural style transformation. The personalized fonts may be transferred to recipients of textual communications to enable the recipient to read messages from a sender in the personalized font of the sender.

    Abstract: A depth sculpturing system comprises an eyewear device that includes a frame, a temple connected to a lateral side of the frame, and a depth-capturing camera. The depth sculpturing system further includes a user input device. Execution of programming by a processor configures the depth sculpturing system to perform functions to track, via the user input device, motion of a two-dimensional input selection from an initial touch point to a final touch point. The depth sculpturing system determines a rotation matrix between an initial ray and a final ray that project to the initial touch point and the final touch point, correspondingly. The depth sculpturing system generates a depth sculptured image by applying the rotation matrix to vertices of an initial depth image. The depth sculpturing system presents, via an image display, the depth sculptured image.
