画像をコード化して伝送する伝送方法であって、A transmission method for encoding and transmitting an image,
完全な量子化マトリクスを構成する複数の成分から、前記画像の量子化係数の高周波成分に対応する成分を打ち切ることにより得られた残りの成分をコード化して伝送し、The remaining components obtained by truncating the component corresponding to the high frequency component of the quantization coefficient of the image from a plurality of components constituting a complete quantization matrix are encoded and transmitted,
前記完全な量子化マトリクスを用いて、前記画像の変換係数を量子化することにより生成される前記量子化係数をコード化して伝送することを特徴とする伝送方法。A transmission method characterized in that the quantization coefficient generated by quantizing the transform coefficient of the image is encoded and transmitted using the complete quantization matrix. 前記残りの成分のコード化は、隣り合う成分どうしの差分値をコード化するものであることを特徴とする請求項１記載の伝送方法。The transmission method according to claim 1, wherein the coding of the remaining components is to code a difference value between adjacent components. 前記残りの成分のコード化は、前記残りの成分のコード化が終了したことを示す特別のシンボルのコード化を含むものであることを特徴とする請求項１記載の伝送方法。2. The transmission method according to claim 1, wherein the coding of the remaining components includes coding of a special symbol indicating that the coding of the remaining components is completed.
