Abstract
A digital image coding device based on wavelet transform technology includes a lower-bitplane replacement section which is provided after a coefficient modeling section and before an arithmetic coding section. The coefficient modeling section converts wavelet coefficients into binary data composed of a plurality of bitplanes for each code-block. The lower-bitplane replacement section replaces a designated number of lower-order bitplanes of the plurality of bitplanes with zero to produce modified binary data. The designated number of low-order bitplanes is designated depending on a noise characteristic of the image capturing device. The arithmetic coding section codes bitplanes of the modified binary data.
