Abstract: Techniques are provided for encoding an extended image such that it is backwards compatible with existing decoding devices. An extended image format is defined such that the extended image format is consistent with an existing image format over the full range of the existing image format. Because the extended image format is consistent with the existing image format over the full range of the existing image format, additional image information that is included in an extended image can be extracted from the extended image. A base version of an image (expressed using the existing image format) may be encoded in a payload portion and the extracted additional information may be stored in a metadata portion of a widely supported image file format.
Abstract translation: 提供了用于对扩展图像进行编码的技术,使得其与现有的解码装置向后兼容。 定义扩展图像格式,使得扩展图像格式与现有图像格式的全部范围内的现有图像格式一致。 由于扩展图像格式与现有图像格式的全部范围内的现有图像格式一致,所以可以从扩展图像中提取包含在扩展图像中的附加图像信息。 图像的基本版本(使用现有图像格式表示)可以被编码在有效载荷部分中,并且所提取的附加信息可以存储在广泛支持的图像文件格式的元数据部分中。
