Abstract
A moving image encoding apparatus which has a similar function to noise elimination by a pre-processing filter without requiring a large amount of calculation and a large apparatus scale. A quantization circuit performs quantization with a quantization step size of a characteristic different from that of a quantization step size which is used by a dequantization circuit and an encoding circuit to eliminate coding of noise components mixed in an input image. An encoding control circuit controls the noise elimination characteristic of the quantization circuit with a noise elimination parameter based on an output of a moving/still discrimination circuit and stored contents of a transmission buffer.
