摘要： An image processing apparatus and an image processing method to preferably transmit/receive or display high dynamic range images. In an image transmission system implementation, metadata is transmitted, the metadata storing information such as peak luminance, color gamut and optical-electro transfer or other characteristics of high dynamic range (HDR) content. An image receiving apparatus utilizes the metadata to perform dynamic range conversion using the metadata to adapt its display to display the HDR content.

摘要： There is provided a decoding device including circuitry configured to receive coded data and conversion information, the coded data pertaining to an image having luminance in a first dynamic range and the conversion information pertaining to a conversion of dynamic range of the luminance of the image from the first dynamic range into a second dynamic range; and decode the received coded data so as to generate the image, wherein the conversion uses a knee function.

摘要： An image processing apparatus and an image processing method which can transmit/receive or display a high-dynamic-range image suitably are provided. An image transmission apparatus transfers, as metadata of content, luminance conversion information, which is for conversion of HDR content (for example, with maximum luminance 2000 nit) into SDR content (having, for example, 100 nit), or differential information. Based on the metadata, an image reception apparatus generates luminance conversion information, in which received HDR content is adapted to a capability of a display (for example, with maximum luminance 500 nit or 1000 nit) in an output destination, and realizes display mapping which is not against an intention of a producer.

摘要： The present disclosure relates to a decoding device, a decoding method, an encoding device, and an encoding method, which are capable of enabling a decoding side to accurately recognize a color gamut of an encoding target image. The decoding device includes circuitry configured to receive an encoded stream including encoded data of an image and color primary information indicating a coordinate of at least one color primary of the image. The circuitry extracts the encoded data and the color primary information from the received encoded stream. The circuitry decodes the encoded data to generate the image. Further, the circuitry adjusts a color space of the generated image based on the extracted color primary information. The present disclosure can be applied to, for example, a decoding device of a high efficiency video coding (HEVC) scheme.
