Abstract
A method and device are provided for rendering an image. The method comprises receiving an image from at least two different camera positions and determining a camera orientation and at least one image attribute associated with each of the positions. A model is then generated of the image based on the attribute and camera orientation associated with the received camera positions of the image. The model is enabled to provide a virtual rendering of the image at a plurality viewing orientations and selectively providing appropriate attributes associated with the viewing orientation.

A method for processing images comprising:
- receiving a plurality of images, wherein the plurality of images were each captured from one of a plurality of camera positions;
- determining a camera position and an image attribute associated with each of the plurality of images;
- and
- generating a bitstream for the plurality of images, wherein the bitstream comprises metadata that provide an indication of the image attribute associated with each of the plurality of camera positions.
A method comprising:
- receiving a bitstream that comprises data representing a plurality of images, wherein the plurality of images were each captured from one of a plurality of camera positions, and wherein the bitstream comprises metadata that provides an indication of an image attribute associated with each of the plurality of camera positions;
- selecting metadata based on an orientation for rendering one or more images at the decoder, wherein the rendering orientation is different from each of the plurality of camera positions;
- and
- rendering the one or more images using the selected metadata.
A decoder comprising:
- a processor configured to:
- receive a bitstream that comprises data representing a plurality of images, wherein the plurality of images were each captured from one of a plurality of camera positions, and wherein the bitstream comprises metadata that provides an indication of an image attribute associated with each of the plurality of camera positions;
- select metadata based on an orientation for rendering one or more images at the decoder, wherein the rendering orientation is different from each of the plurality of camera positions;
- and
- rendering the one or more images using the selected metadata.
