Abstract
A method comprising: forming an extended field-of-view (FOV) picture; deriving a prediction signal by using the extended-FOV picture; and using the prediction signal to encode at least a part of a current source picture to a current coded picture.
Claims20
An apparatus comprising:
- at least one processor;
- and
- at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to perform:
- obtaining a previous source picture;
- forming an extended field of view (FOV) picture from the previous source picture;
- encoding the extended FOV picture to a previous coded picture;
- wherein the encoding of the extended FOV picture to the previous coded picture comprises reconstructing a previous reconstructed picture;
- and
- encoding a current source picture to a current coded picture, based on the previous reconstructed picture;
- and
- wherein the encoding of the current source picture to the current coded picture comprises reconstructing a current reconstructed picture.
