摘要： To allow a finer quantization control according to the property of an image within a macroblock, quantization parameter values are allowed to be changed in units of sub-blocks equal to or smaller than the macroblock in a similar manner as in motion compensation and orthogonal transform processes. A finer-tuned quantization control is performed, for example, by selecting fine and coarse quantization parameters respectively for corresponding sub-blocks if a plurality of images having different properties coexist within the macroblock.

摘要： Frequently occurring DCT coefficients F(u, v) are predictable. Accordingly, values f.sub.u,v,F,(u,v) (x, y) for the frequently occurring DCT coefficients are calculated and stored, in advance, in a table. Among input DCT coefficients F(u, v), only non-zero DCT coefficients are processed. It is determined whether or not the table contains values f.sub.u,v,F(u,v) (x, y) for a given non-zero DCT coefficient. If the table contains the values, they are read out of the table, and if not, they are directly calculated. The read or calculated values are added to pixels (x, y), respectively, to provide pixel values (x, y).
