Abstract
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.
Claims20
A decoding device comprising:
- 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.
A decoding method of causing a decoding device to perform:
- receiving 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
- decoding the received coded data so as to generate the image,
- wherein the conversion uses a knee function.
A coding device comprising:
- circuitry configured to
- set conversion information pertaining to a conversion of dynamic range of a luminance of an image from a first dynamic range into a second dynamic range;
- and
- code the image having luminance in the first dynamic range so as to generate coded data,
- wherein the conversion uses a knee function.
