Abstract
This invention performs encoding with high encoding efficiency while suppressing image quality degradation when RAW image data obtained by imaging is to be encoded. Hence, an imaging apparatus that encodes an image captured by an image sensor includes a plane converting unit configured to convert RAW image data of a Bayer array obtained by the image sensor into a plurality of planes each comprised of a pixel of a single component, a frequency transforming unit configured to generate a plurality of subbands by frequency-transforming each of the obtained planes, a non-linear converting unit configured to non-linearly convert coefficient data forming each of the subbands based on camera information related to imaging in the imaging apparatus, and an encoding unit configured to encode by quantizing the coefficient data obtained by the non-linear conversion by the non-linear converting unit.
