1. A device, comprising:
one or more processors configured to:
determine an aspect ratio of an immersive image and one or more additional characteristics of the immersive image; and
determine a format of the immersive image using the determined aspect ratio and the determined one or more additional characteristics of the immersive image,
wherein the one or more processors are configured to divide the immersive image depending on the determined aspect ratio either:
vertically into a first image and a second image of equal size such that the first image and the second image are arranged side-by-side, or
horizontally in the first image and the second image such that the first image and the second image are arranged on top of each other
wherein, in a transition from the first image to the second image, each first pixel of a plurality of first pixels of the first image is adjacent to a corresponding second pixel of a plurality of second pixels of the second image;
wherein the one or more processors are configured to:
determine for each first pixel of the plurality of first pixel a difference between the pixel value of the first pixel and the pixel value of the second pixel adjacent to the first pixel, wherein the aggregated differences between the plurality of first pixels and the plurality of second pixels is an additional characteristic of the one or more additional characteristics of the immersive image,
determine respective features of the first image and the second image using a feature detector,
determine a feature metric using a feature matcher, wherein the feature metric comprises matching features of the first image and the second image having a first value for the first image and a second value for the second image, and
determine, whether the immersive image comprises a monoscopic format or a stereoscopic format, using the feature metric and the aggregated differences between the plurality of first pixels and the plurality of second pixels.
