Coding apparatus for image compression |
摘要 |
A coding apparatus for image compression which includes a transformer that transforms image data into a plurality of transform coefficients arranged in a matrix; a quantizer that quantizes each of the transform coefficients into a coefficient data of a predetermined number of bits; a data divider that divides the coefficient data into a fixed-length data part and a variable-length data part and a variable-length encoder that encodes the variable-length data part into a variable-length code.
