Image processing apparatus, image processing circuit, and image processing method

An image processing apparatus that generates an image by decoding information codes of code-block-related information items from code data in which the image is encoded, the information codes being related to code-blocks or different levels into which the image has been divided by a wavelet transform and being generated using separate tag trees corresponding to the different levels, the image processing apparatus comprising:

• a coordinate generating unit that generates an x coordinate and a y coordinate of each of the code-blocks of each of the levels wherein a unit in an x direction and in a y direction is defined by a size of the individual code-blocks of the corresponding level;
• and
• an address generating unit that generates a multiple of a combination value of a bit combination of the y coordinate and the x coordinate of each code-block as an address for storing the information code of the code-block in a first storage unit.

An image processing circuit that divides an image into code-blocks of different levels by a wavelet transform, generates information codes of code-block-related information items related to the code-blocks of the different levels using separate tag trees corresponding to the different levels, and generates code data in which the image is encoded, the image processing circuit comprising:

• a coordinate generating unit that generates an x coordinate and a y coordinate of each of the code-blocks of each of the levels wherein a unit in an x direction and in a y direction is defined by a size of the individual code-blocks of the corresponding level;
