Abstract: In an image encoding apparatus, conversion data obtained by converting image information onto a frequency region, and corresponding to several frames are parallelly output using a one-frame-period delay circuit. The parallelly output conversion data are quantized by a quantization circuit, and a data amount to be obtained when the quantized data are encoded is obtained by a variable-length coding circuit. The data amount information is input to a coefficient operation circuit for determining a quantization step of the next stage. Conversion data quantized according to an output from the coefficient operation circuit are encoded, and the encoded data are output.
