[0004] BACKGROUND

[0005] Today, selfies are common and popular so that people use their own smartphone to take pictures of themselves with friends in different situations and poses.

[0006] Augmented Reality, AR, glasses are foreseen to be increasingly used, and in the future, there is expected to be a lot of people wearing AR glasses in public. Furthermore, AR glasses are expected to have cameras capable of taking photos of the surroundings.

[0059] DETAILED DESCRIPTION

[0060] Aspects of the present disclosure will be described more fully hereinafter with reference to the accompanying drawings. The apparatus and method disclosed herein can, however, be realized in many different forms and should not be construed as being limited to the aspects set forth herein. Like numbers in the drawings refer to like elements throughout.

[0061] The terminology used herein is for the purpose of describing particular aspects of the disclosure only and is not intended to limit the invention. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

[0062] Some of the example embodiments presented herein are directed towards a method for capturing an image of a first wireless communication equipment, UE1, by a second wireless communication equipment, UE2. As part of the development of the example embodiments presented herein, a problem will first be identified and discussed.

[0063] A selfie is a self-portrait photograph taken by an individual using a smartphone or digital camera, typically at arm's length or with the help of a selfie stick. The term "selfie" is a combination of "self" and "portrait," emphasizing that it is a self-captured image. Selfies have become incredibly popular in recent years, especially with the widespread use of smartphones and social media platforms.

[0064] In this disclosure a stereo image refers to a visual representation that conveys a sense of three- dimensional depth by presenting two slightly offset 2D images to each eye. This technique mimics the way humans perceive depth in the real world through binocular vision. The brain processes the differences between the images seen by the left and right eyes, creating a perception of depth and allowing us to gauge distances. In the context of photography or computer graphics, creating a stereo image typically involves capturing or rendering two slightly different perspectives of the same scene. These two images are then presented separately to each eye, usually using special glasses with lenses that filter the images or by using other methods like autostereograms.

[0065] The present inventors realized that the problem of obtaining a selfie of a user wearing an augmented reality, AR, device such as an AR headset aka AR glasses may be solved by utilizing existing technology having image sensors in the surroundings of the person, such as for example other wireless equipment either carried by other users or by a UAV, or Unmanned Aerial Vehicle, is a type of aircraft that operates without a human pilot on board. UAVs are also commonly known as drones. These vehicles are designed to fly autonomously or be remotely controlled by a human operator.
