Method and apparatus for encoding video data, method and apparatus for decoding video data, and program recording medium

An apparatus for decoding video data, the apparatus comprising:

• a data reading unit to read the video data including raw image data that is output from an image pickup device in frame units and encoded, encoding information that is required to decode the encoded raw image data, and image pickup device information that is required to develop the raw image data;
• an encoding information extractor to extract the encoding information from the video data;
• a decoder to decode the encoded raw image data based on the encoding information to generate the raw image data;
• an image pickup device information extractor to extract the image pickup device information from the video data, wherein the extracted raw image data was not developed according to the image pickup device information;
• and
• a developer to develop the raw image data based on the image pickup device information to generate image data.

A method of encoding video data, the method comprising:

• generating encoded raw image data by encoding raw image data that is output from an image pickup device in frame units;
• generating encoding information that is required to decode the encoded raw image data;
• obtaining image pickup device information that is required to develop the raw image data, wherein the raw image data that is encoded was not developed according to the image pickup device information;
• and
• generating the video data including the encoded raw image data, the encoding information, and the image pickup device information.
