Abstract: An AR system is provided, the AR system including one or more sensors, storage, one or more communications modules, and one or more processors. The one or more sensors generate sensed data representing at least part of an environment in which the AR system is located. The one or more communications modules transmit localization data to be used in determining the location and orientation of the AR system. The one or more processors are arranged to obtain sensed data representing an environment in which the AR system is located, process the sensed data to identify a first portion of the sensed data which represents redundant information, derive localization data, wherein the localization data is derived from the sensed data and the first portion is obscured during the derivation of the localization data, and transmit at least a portion of the localization data using the one or more communication modules.

Abstract: Examples of the present disclosure relate to methods for performing image processing. In one such example, a model of an environment is stored. Image data representative of a captured observation of the environment is obtained and the image data is processed using an object classifier to determine whether one or more objects belonging to a plurality of predetermined classes of objects is present in the environment. The stored model is updated based on the processing. In response to determining at least one of the one or more objects is present, object class characteristic data indicative of a characteristic of the at least one object that is determined to be present is retrieved and a probability of change associated with the at least one object is determined on the basis of the object class characteristic data. The updating of the stored model is adjusted based on the determined probability of change.

Abstract: A computing device 2, such as a general-purpose smartphone or general-purpose tablet computing device, comprises one or more inertial sensors and an image sensor. The device 2 produces stereoscopic images of a virtual environment on the display during a virtual reality (VR) session controlled by a user of the computing device. The device conducts visual odometry using at least image data received from the image sensor, and selectively activates and deactivates the visual odometry according to activity of the user during the virtual reality session. When the visual odometry is activated, the device controls the virtual reality session by at least position information from the visual odometry. When the visual odometry is deactivated, the device controls the virtual reality session by at least orientation information from the one or more inertial sensors.

Abstract: A graphics processing apparatus (2) performs tile based compositing operations. Tile metadata includes flag data (tfd), such as transparency and/or intensity flag data, indicating whether a given input graphics tile make less than a predetermined first threshold level of contribution or more than a second predetermined threshold level of contribution to a corresponding output graphics tile. For example, if an input graphics tile is transparent, then its reading from a memory (6) and/or subsequent processing may be suppressed. If a given input graphics tile is opaque, then any underlying input graphics tiles were are obscured may have their reading and/or further processing suppressed.

Abstract: Image data is subject to compression and decompression when it is respectively written to and read from a frame buffer. If a portion of the image data is identified as static (subject to less than a threshold amount of change for greater than a threshold time), then compression control parameters used for compression of that portion of the image are adjusted so as to increase the compression ratio achieved, hold the degree of lossiness substantially constant and increase the energy consumed while compressing that portion. The increased energy consumption during this high compression ratio compression is likely compensated for by a reduction in energy subsequently consumed when writing that frame-buffer image data to the frame buffer and reading that frame-buffer image data multiple times from the frame buffer. The compression characteristics varied may be to increase the block size used in the compression. Other variations in compression applied may be to change from single-pass compression to multi-pass compression, switch compression on and off altogether, or reorder the data when it has been compressed so as to match the order it will be read and so achieve support for longer read burst.

Abstract: An image processing system for an extended reality, XR, device comprising an eye-tracking subsystem, for determining a focus region of the eye, and a processor. The processor is configured to process application data to render image content for an application for display on the XR device, and obtain metadata indicating that a virtual object is to be generated as a hologram as part of the image content for display. Based on a determination that the virtual object belongs to a predetermined class of objects and is to be displayed in the focus region, the processor performs, using a neural network corresponding to the predetermined class of objects, foveated processing of the image content, including at least part of the hologram, such that relatively high-quality image content is generated for display in the focus region and relatively low-quality image content is generated for display outside the focus region.

Abstract: A head-mounted display (HMD) comprising a first side for facing a user of the HMD, a second side opposite to the first side, and a reflective layer for at least partially reflecting incident light incident on the second side. At least one processor of the HMD is configured to obtain luminance data indicative of a luminance of the incident light and control a display device, based on the luminance data, to control a luminance of a portion of emitted light directed towards the user of the HMD during the display of the image. Further examples relate to an HMD with a display device configured to emit light of at least one predetermined wavelength range during display of an image by the display device, and a layer arranged to at least partially prevent transmission of the light of the at least one predetermined wavelength range outward from the HMD.

Abstract: A device has a content processing component operable in first and second content processing states, a display, at least one sensor operable to output sensor data indicative of at least one eye positional characteristic of a user, and a processor. The processor is configured to process the data, and in the first processing state, determine a region of the display corresponding to a foveal region of an eye of a user, and perform foveated processing of content to be displayed on the display such that a relatively high-quality video content is generated for display in the region and a relatively low-quality video content is generated for display outside the region. The second processing state is entered in response to a trigger. In the second processing state, the foveated processing used is overridden such that relatively low-quality video content is generated for display in at least a portion of the region.
