Data is quantized on the basis of a plurality of coefficients C.sub.1 for controlling a quantizing step. As a result of the quantization, reference encoding data items Nb1 to Nb4 are obtained. Coefficients C5 to C7 for controlling the quantizing step are generated when image data which is delayed by one frame is quantized. At this time, the data items Nb1 to Nb4 are output by bit-shifting the result of the quantization.
