ABSTRACT:
An encoding method of losslessly encoding picture data is disclosed. The picture data are composed of pixel data. The pixel data whose number of quantizer bits is larger than eight bits are separated into a first portion and a second portion. The first portion is composed of eight bits on an LSB side. The second portion is composed of remaining bits on an MSB side excluding the first portion. A first encoding process is losslessly performed for the first portion. A second encoding process is losslessly performed for the second portion. The second encoding process is different from the first encoding process.
