1. An image processing apparatus comprising:
- an image element allocation unit that allocates image elements included in input image data to a plurality of layers and to any of a plurality of mutually-different coding processings, in accordance with a allocation reference;
a coding unit that encodes, by the respective coding processings, the image elements allocated to the respective coding processings by the image element allocation unit; and
a reference change unit that changes the allocation reference applied by the image element allocation unit,wherein the plurality of layers include a first layer to which a first coding processing is applied and a second layer to which a second coding processing is applied, the second coding processing realizing a compression ratio higher than that of the first coding processing.

12. A computer-implemented image processing method comprising:
-
using a processor to perform the steps of; changing an allocation reference used for allocation of image elements; allocating the image elements included in input image data to a plurality of layers and to any of a plurality of coding processings, in accordance with the changed allocation reference; and encoding the image elements allocated to the respective coding processings by the respective coding processings, wherein the plurality of layers include a first layer to which a first coding processing is applied and a second layer to which a second coding processing is applied, the second coding processing realizing a compression ratio higher than that of the first coding processing.

13. A storage medium readable by a computer, the storage medium storing a program of instructions executable by the computer to perform a function for image processing, the function comprising:
-
changing an allocation reference used for allocation of image elements; allocating the image elements included in input image data to a plurality of layers and to any of a plurality of coding processings, in accordance with the changed allocation reference; and encoding the image elements allocated to the respective coding processings by the respective coding processings, wherein the plurality of layers include a first layer to which a first coding processing is applied and a second layer to which a second coding processing is applied, the second coding processing realizing a compression ratio higher than that of the first coding processing.
