    Abstract: Various implementations disclosed herein improve the appearance of captured video by accounting for light-based flicker and/or other factors affecting the appearance of video captured by a wearable electronic device. Some implementations are used with head-mounted devices (HMDs) that relay one or more front-facing camera feeds to display panels in front of the user's eyes. Some implementations adjust the exposure of one or more cameras of such a device based on assessing the lighting in the physical environment being captured in images/video by the cameras. Camera exposure may be adjusted (e.g., using discrete levels of exposure that are an even multiple of a light flicker rate) to reduce the appearance of flicker from one or more light sources in the physical environment. Whether and how to adjust exposure to reduce flicker may be based on environmental characteristics corresponding to visibility/objectionability of flicker from one or more light sources.

    Abstract: Various implementations disclosed herein include devices, systems, and methods that adjust a brightness characteristic of virtual content (e.g., virtual objects) and/or real content (e.g., passthrough video) in views of an XR environment provided by a head mounted device (HMD). The brightness characteristic may be adjusted based on determining a viewing state (e.g., a user's eye perception/adaptation state). A viewing state, such as a user's eye perception/adaptation state while viewing a view of an XR environment via an HMD, may respond to a brightness characteristic of the XR environment that the user is seeing, which is not necessarily the brightness characteristic of the physical environment upon which the view is wholly or partially based.

    Abstract: Electronic devices such as mixed reality devices may present virtual objects at a display and provide a virtual magnifier to alter (e.g., magnify) the virtual objects. In one or more implementations, the virtual magnifier magnifies a first virtual object and subsequently magnifies a second virtual object. The electronic device may provide one or more effects, such as initially maintaining the current size of the second virtual object and subsequently adjusting the size of the second virtual object based on the first virtual object, including the relative depth between the first virtual object and the second virtual object. In one or more implementations, a process for stabilization of a magnified object is applied in circumstances when the change in position of the electronic device or change in user's gaze location is at or above a threshold.
