摘要： The invention is made in the field of HDR video image encoding and decoding.
A method for encoding an HDR video image of high dynamic range using LDR video images is described. The LDR video images provide differently exposed lower dynamic range depictions of the HDR video content and wherein the LDR video images are encoded as different views of a multi-view coding scheme.
The method described comprises using processing means for selectively pre-processing, prior to encoding, one of the LDR video images according to a parameterized pre-processing parameterized according to at least one parameter encoded in metadata.
This allows to better compensate for the effects of different exposures and enables efficient inter-exposure prediction.

摘要： The invention is made in the field of coding of images of high dynamic range.
The invention is based on the concept of Frame Compatible format. The idea is to transport, in a frame, down-sampled LDR content together with additional information allowing reconstructing HDR content from the LDR content.
Thus, it is proposed a method of encoding an HDR image of high dynamic range according to claim 1. Said method comprises down-sampling (DWN) an LDR image and additional data, the LDR image providing a lower dynamic range depiction of the HDR image content and the additional data allowing for reconstructing the HDR image from the LDR image. Said method further comprises arranging (PCK), in a frame, the down-sampled LDR image and the down-sampled additional data, wherein arrangement is side-by-side in case of horizontal down-sampling and top-and-bottom in case of vertical down-sampling and encoding (AVC) the frame.
