Abstract:
1. An image processing apparatus for generating code data, the image processing apparatus comprising: a wavelet transform circuit configured to divide an image into code-blocks of different levels by a wavelet transform; a code generating circuit configured to generate 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; a coordinate generating circuit configured to generate 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 circuit configured to generate 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 circuit; and wherein the multiple of the combination value is calculated by multiplying the combination value by a maximum bit length of the information code for each of the different information codes.
