Abstract
Methods and apparatus provide for capturing with a camera a wide field of view image having a field of view that is wider than a field of view subsequently displayed to the recipient, capturing at least orientation information of the camera as extrinsic camera parameters, and streaming successive images along with corresponding extrinsic camera parameters. Alternative provisions include receiving a stream comprising successive wide field of view images captured by a camera, and at least corresponding orientation information of the camera, receiving indications of at least an orientation of a head mounted display ‘HMD’ having a field of view smaller than the wide field of view images, aligning a respective predetermined main area of interest in the received images with a viewpoint corresponding at least to a predetermined orientation of the HMD, and displaying the result on the HMD, based on at least the received orientation information of the camera and the indicated orientation of the HMD.
