文件生成设备、文件生成方法、文件再现设备及文件再现方法
Abstract:
本技术涉及文件生成设备、文件生成方法、文件再现设备和文件再现方法，使得可以利用高动态范围(HDR)图像。生成存储目标轨道的文件。所述目标轨道包含HDR信息，HDR信息包括特征信息和转换信息，特征信息表示具有比标准(STD)图像的动态范围更高的动态范围的HDR图像的亮度的特征，转换信息表示用于将STD图像转换成HDR图像或将HDR图像转换成STD图像的转换规则。目标轨道还包含HDR指定信息，HDR指定信息表示要被应用于目标轨道的HDR信息。本技术可以应用于例如存储诸如字幕的图像的数据以及要被应用于MP4文件等中的所述图像的HDR信息的情况。
Abstract(English):

This technology pertains to a file generation device, a file generation method, a file reproduction device, and a file reproduction method that make it possible to make use of high dynamic range (HDR) images. A file in which a target track is stored is generated. Said target track contains HDR information comprising the following: characteristics information that indicates HDR-image luminance characteristics, HDR images having higher dynamic ranges than standard (STD) images; and conversion information that indicates conversion rules for converting an STD image to an HDR image or vice versa. The target track also contains HDR specification information that specifies HDR information to be applied to the target track. This technology can be applied, for example, when storing data for images such as subtitles and HDR information to be applied to said images in an MP4 file or the like.
