Abstract
Several approaches are disclosed for combining HDR and 3D image structure analysis and coding, in particular an encoding apparatus for encoding a first view high dynamic range image and a second view high dynamic range image comprising: first and second HDR image receivers (203, 1201) arranged to receive the first view high dynamic range image and a second view high dynamic range image; a predictor (209) arranged to predict the first view high dynamic range image from a low dynamic range representation of the first view high dynamic range image; and a view predictor (1203) to predict the second view high dynamic range image from at least one of the first view high dynamic range image, a low dynamic range representation of the second view high dynamic range image, or a low dynamic range representation of the first view high dynamic range image.
