前記判定手段は、
前記ＬＤＲ画像の画素数が前記取得手段で取得した画素数を上回った場合に前記ＨＤＲ差分符号化データの復号を否として判定し、
前記ＬＤＲ画像の画素数が前記取得手段で取得した画素数以下の場合には、前記輝度成分の分布に基づく判定を行う
ことを特徴とする請求項４に記載の画像復号装置。 The determination means includes
When the number of pixels of the LDR image exceeds the number of pixels acquired by the acquisition unit, it is determined that the decoding of the HDR differential encoded data is not possible,
The image decoding apparatus according to claim 4 , wherein when the number of pixels of the LDR image is equal to or less than the number of pixels acquired by the acquisition unit, the determination based on the distribution of the luminance component is performed. コンピュータに読み込ませ実行させることで、前記コンピュータに、請求項１１又は１２に記載の画像復号装置の制御方法の各工程を実行させるためのプログラム。 A program for causing a computer to execute each step of the control method of the image decoding device according to claim 11 by being read and executed by a computer.
