Title:
ＳＬ－ＨＤＲ２形式の中間ダイナミックレンジビデオ信号を処理する方法及び装置
Document Type and Number:
Japanese Patent JP7483634
Kind Code:
B2
Abstract:
Different implementations are described, particularly implementations for processing a medium dynamic range video signal are presented. In a method for processing such a video signal a medium dynamic range video signal and associated metadata are received, wherein the metadata include data representative of a peak luminance value of the medium dynamic range video signal. In addition, data representative of a peak luminance value of a presentation display are received. It is determined whether the peak luminance value of the medium dynamic range video signal is greater or lower than the peak luminance value of the presentation display. A processor is configured based on the determination, wherein the processor has a first mode to reconstruct a high dynamic range video signal based on a received standard dynamic range video signal and associated metadata, and a second mode to optimize a received high dynamic range video signal for the rendering device. The medium dynamic range video signal is processed by the processor in the first mode if the peak luminance value of the medium dynamic range video signal is smaller than the peak luminance value of the presentation display and in the second mode if the peak luminance value of the medium dynamic range video signal is greater than the peak luminance value of the presentation display.
