Abstract
The present technology relates to a decoding device and a decoding method, and an encoding device and an encoding method that enable images that configure a packed image to be reliably displayed when an encoded stream is decoded and displayed. A decoding unit decodes an encoded data, the encoded data being an encoded packed image in which a plurality of images is packed, and generates the packed image. A display control unit identifies the images that configure the packed image based on packing SEI preferentially used when the packed image is displayed. The present technology can be applied to a decoding device, for example.
Claims11
An encoding device comprising:
- an encoding unit configured to encode data, the data including a packed image in which a plurality of images are packed, a packing area information that indicates an image area of an identified image, a cropping information in a sequence parameter set (SPS) that indicates a cropped area of the identified image, and a packing arrangement type information that indicates whether the packed image is in a side-by-side packing arrangement,
- wherein the packing area information and the packing arrangement type information are used for selecting between using the image area to identify a display area and using the cropping information to identify the display area,
- wherein the packing area information and the packing arrangement type information are used for identifying the display area by using the image area, instead of the cropping information, that is displayed as a result of decoding the packed image, and
- wherein the encoding unit is implemented via at least one processor.
A decoding method comprising:
- encoding data, the data including a packed image in which a plurality of images are packed, a packing area information that indicates an image area of an identified image, a cropping information in a sequence parameter set (SPS) that indicates a cropped area of the identified image, and a packing arrangement type information that indicates whether the packed image is in a side-by-side packing arrangement,
- wherein the packing area information and the packing arrangement type information are used for selecting between using the image area to identify a display area and using the cropping information to identify the display area, and
- wherein the packing area information and the packing arrangement type information are used for identifying the display area by using the image area, instead of the cropping information, that is displayed as a result of decoding the packed image.
A non-transitory computer-readable medium having encoded thereon a program, which when executed by a computer causes the computer to execute a method, the method comprising:
- encoding data, the data including a packed image in which a plurality of images are packed, a packing area information that indicates an image area of an identified image, a cropping information in a sequence parameter set (SPS) that indicates a cropped area of the identified image, and a packing arrangement type information that indicates whether the packed image is in a side-by-side packing arrangement,
- wherein the packing area information and the packing arrangement type information are used for selecting between using the image area to identify a display area and using the cropping information to identify the display area, and
- wherein the packing area information and the packing arrangement type information are used to identify the display area by using the image area, instead of the cropping information, that is displayed as a result of decoding the packed image.
