The present invention is characterized in that a macroblock motion vector is input from the estimation means and a first frame memory unit from which the previous macroblock is input from the second addition means and a DC value of the previous macroblock from the first frame memory unit are calculated A DC value removing means for removing the DC value from the previous macroblock, a normalizing means for normalizing a previous macroblock from the DC value removing means, a current macroblock from the second frame memory means, An inner product calculation means in which the previous macroblock from the normalization means and the current macroblock from the first subtraction means are internally calculated, and an inner product calculation value from the inner product calculation means is quantized The first quantization means, the previous macroblock from the normalization means and the inner product calculation means Characterized in that configured in the first addition means the inner product calculations of the emitter and the predicted macroblock from which gopsan gopsan gopsan means and, gopsan this means that the DC value from the DC removal means of the addition value.
