Abstract

An encoding method for first and second relatively high dynamic range original images, representing different views of the same scene. The method comprises tone mapping the first relatively high dynamic range original image to create a first relatively low dynamic range image; creating difference data which represents the difference between the first relatively low dynamic range image and the first relatively high dynamic range image; tone mapping the second relatively high dynamic range original image to create a second relatively low dynamic range image; using the first and second relatively low dynamic range images to create encoded image data representing the first and second relatively low dynamic range images; and creating a package comprising the encoded image data and the difference data. In some embodiments the method is carried out on a series of first original images constituting a first relatively high dynamic range original video stream, and a series of second original images constituting a second relatively high dynamic range original video stream.
