Abstract: Examples of the disclosure enable image augmentations to be used with images of users wearing head mounted items. In examples of the disclosure an apparatus can be configured to use gaze tracking to determine a location of a user's pupil wherein the user is wearing a head mounted item. The apparatus can also be configured to enable display of an indication of the location of the user's pupil so that the indication is visible on a surface of the head mounted item. The indication is configured to be used for positioning at least one image augmentation for a captured image comprising the user.

Abstract: Examples of the disclosure relate to optical apparatus, modules, and devices. Examples of the disclosure relate to an apparatus including a light guide. The light guide includes at least an in-coupling diffractive member configured to in-couple one or more input beams of light into the light guide from a light engine, an expander configured to expand the one or more input beams of light, and an out-coupling diffractive member configured to out-couple the one or more expanded beams of light from the light guide. The out-coupling diffractive member includes at least a first section configured to out-couple the one or more expanded beams of light with a first efficiency and at least a second section configured to out-couple the one or more expanded beams of light with a second efficiency, where the second efficiency is lower than the first efficiency.

Abstract: An apparatus including a first display means projecting light in a first band of wavelengths to form a first image at a first eye of a user and for projecting light in the first band of wavelengths to form a second image at a second eye of the user; a second display for projecting light in a second band of wavelengths to form a third image at the first eye of the user and at the second eye of the user, wherein the first band of wavelengths and the second band of wavelengths are different.

Abstract: An apparatus including: a display comprising an exit pupil expander including an outcoupling element configured to outcouple light in a forward direction towards a user and also in a backward direction away from the user; and a dynamically controllable reflector configured to provide selective reflection for light outcoupled from the exit pupil expander, wherein the selectivity of reflection of the light is dynamically controllable and wherein the selective reflection of the light is in a backwards direction back towards the user.

Abstract: An apparatus comprising: a first display for displaying a first image; a second display for displaying a second image; a reflection surface configured to reflect the first image displayed on the first display towards a user of the apparatus; means for user adjustment of an angle between the first display and the reflection surface; and a controller configured to adapt the first image displayed on the first display so that it can be viewed via reflection and configured to control display of the first image on the first display and the second image on the second display wherein simultaneous viewing of a reflection of the first image displayed on the first display in the reflection surface and of the second image displayed on the second display creates a combination image.

Abstract: Examples of the disclosure are configured to reduce the effects of leaked images from mediated reality headsets. Examples of the disclosure comprise determining that an object is positioned relative to a mediated reality headset such that one or more portions of an image displayed by the mediated reality headset could be leaked in a field of view of the object. Examples of the disclosure also comprise identifying one or more portions of the image that are displayed by the mediated reality headset such that leakage of those one or more portions is expected to be in the field of view of the object. Examples of the disclosure also comprise causing modification of the display of the image by the mediated reality headset wherein the modification reduces light leakage for the one or more portions of the image that are identified as being displayed such that leakage of those one or more portions is expected to be in the field of view of the object.

Abstract: Examples of the disclosure are configured to reduce the effects of reflections from the surfaces of head mounted items such as mediated reality headsets or sunglasses. Examples of the disclosure are configured to detect that a user is using a device with a display and that the user is wearing a head mounted item comprising one or more reflective surfaces. The examples of the disclosure then cause a light pattern to be projected onto the one or more reflective surfaces wherein the pattern is projected to mask a reflection of the display of the device on the one or more reflective surfaces.

Abstract: An apparatus including a first substrate including a first incoupling diffractive optical element configured to couple light into the first substrate, and a first outcoupling diffractive optical element configured to output, from the first substrate, light that has been coupled into the first substrate; and a second substrate including a second incoupling diffractive optical element configured to couple light into the second substrate, and a second outcoupling diffractive optical element configured to output, from the second substrate, light that has been coupled into the second substrate; wherein the first and second incoupling diffractive optical elements are substantially inverse of each other and the first and second outcoupling diffractive optical elements are substantially inverse of each other.
