Abstract:
1. An image processing apparatus, comprising: a coding part partitioning a wavelet coefficient obtained by performing two-dimensional discrete wavelet transform on image data into bit-planes and generating coded data of the image data by performing entropy coding on the wavelet coefficient for each of the bit-planes; a first memory accommodating a size of a coded data portion generated from the wavelet coefficient for each of the bit-planes through the execution of the entropy coding; a second memory accommodating the coded data of the image data; a setting part setting a target size of the coded data; and a data size adjustment part adjusting the size of the coded data such that the size of the coded data falls within an acceptable range, which includes the target size set by the setting part, by sequentially discarding a portion of the coded data in a least significant order from the second memory based on the size of the coded data portion corresponding to each of the bit-planes in the first memory.
