Abstract: A method is disclosed, comprising providing video data representing a plurality of frames of virtual reality content captured by a camera. A further step comprises determining a reference depth or object within the content. A further step comprises adjusting the position of content in one or more frames, based on the reference depth or object, to compensate for the movement of the camera during capture.

Abstract: Certain examples of the present invention relate to an apparatus, method, computer program and system for use in gaze dependent foveated rendering. Certain examples provide an apparatus including at least one processor; and at least one memory including computer program code; the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to perform adapting a gaze dependent foveated rendering process in response to a determination of a sub-optimal operational condition of the gaze dependent foveated rendering process.
