Abstract
The present invention provides a technique for encoding Bayer array RAW image data that responds to whether priority is placed on encoding efficiency or on image quality. To that end, a first plane transforming unit transforms the RAW image data into R, G0, G1, and B planes. A second plane transforming unit transforms the RAW image data into a luminance plane and three color difference planes, each constituted of a different color difference component. It is then determined whether to encode using the first plane transforming unit or the second plane transforming unit, and the planes are then encoded according to the determination.
