Portable electronic device for mixed reality headset

A method by a portable electronic device for a mixed reality, MR, headset including a lens through which a user wearing the MR headset can view real-world features and including a holder configured to retain the portable electronic device in a defined orientation relative to the lens, wherein a display device of the portable electronic device is arranged to display information that is projected on the lens for reflection directly or indirectly toward the user's eyes and a camera of the portable electronic device, the method comprising:

• processing the video frames from the camera of the portable electronic device to identify locations of at least one real-world feature;
• displaying information at locations on the display device of the portable electronic device;
• and
• controlling at least one of the processing of the video frames to identify locations of at least one real-world feature and the displaying of the information on the display device, to at least partially reduce occurrence in the video frames of the information that is displayed by the display device,
• wherein the controlling of the processing of the video frames comprises controlling the processing of the video frames to identify locations of at least one real-world feature to occur during second time durations while the information is not displayed on the display device and further controlling the processing of the video frames to identify locations of at least one real-world feature to not occur during first time durations while the information is displayed on the display device, and
• wherein the controlling of the displaying of the information on the display device comprises controlling the displaying of the information on the display device during the first time durations to occur while the processing is not performed on the video frames to identify locations of at least one real-world feature and further controlling the ceasing of the displaying of the information on the display device during the second time durations to occur while the processing is being performed on the video frames to identify locations of at least one real-world feature.
