Image processing apparatus and method

An image processing method comprising:

• setting additional information including packing information related to packing processing of rearranging each pixel data of RAW data that is image data before demosaicing processing is performed according to the degree of correlation;
• and
• encoding the RAW data subjected to the packing processing, and generating a bit stream including obtained encoded data and the additional information set by the setting unit.

An image processing apparatus comprising:

• a decoding unit configured to decode encoded data that is included in a bit stream and is encoded RAW data that is image data before demosaicing processing is performed;
• and
• an extraction unit configured to extract, from additional information included in the bit stream, packing information that is information related to the packing processing, and is to be used in unpacking processing of returning the pixel data of the RAW data subjected to the packing processing, the RAW data having been obtained by decoding the encoded data by the decoding unit, to an arrangement before the packing processing is performed.
