Image processing apparatus that decomposes an image into components of different properties

An image forming apparatus, comprising:

• the image processing apparatus that encodes an image into a codestream, when the image processing apparatus comprises a dividing unit to divide an image into a plurality of regions based on a division signal, a generating unit to generate components of the respective divided regions, an encoding unit to encode the generated components, and a combining unit to combine the encoded components into a codestream,
• a storing unit to store the codestream;
• an image decoding apparatus to decode the codestream stored in the storing unit into the image;
• and
• an image forming unit to form the decoded image.

A method of processing an image, comprising:

• dividing an image into a plurality of regions based on a division signal;
• generating components of the respective divided regions;
• encoding the generated components;
• and
• combining the encoded components into a codestream.

An article of manufacture having one or more recordable medium storing instructions which, when executed by a computer, cause the computer to perform a method comprising:

• dividing an image into a plurality of regions based on a division signal;
• generating components of the respective divided regions;
• encoding the generated components;
• and
• combining the encoded components into a codestream.
