发明名称 METHOD AND DEVICE FOR DECODING A HDR PICTURE FROM A BITSTREAM REPRESENTING A LDR PICTURE AND AN ILLUMINATION PICTURE
摘要 <p>The present disclosure generally relates to a method and device for decoding an HDR picture from a bitstream representing a LDR picture and an illumination picture. The method comprising: - obtaining a decoded version of the HDR picture by multiplying the sample values of a decoded version of the LDR picture by the sample values of the decoded version of the illumination picture; and - obtaining a color value expressed in an output color space for each sample value of the decoded version of the HDR picture, the method is characterized in that it further comprises: - obtaining a color value expressed in the output color space for each sample value of a decoded version of the LDR picture just before multiplying said color values by the sample values of the decoded version of the illumination picture.</p>
