摘要
Methods and apparatus are provided for bit depth scalable video encoding and decoding utilizing tone mapping and inverse tone mapping. An apparatus includes an encoder for encoding picture data for at least a portion of a picture by generating an inter-layer residue prediction for the portion using a tone mapping function and an inverse tone mapping function. The tone mapping function and the inverse tone mapping function perform a conversion of the inter-layer residue prediction from a residue domain to a pixel domain for bit depth scalability while maintaining a same bit depth representation.
