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.
