Abstract
The present disclosure relates to an image processing device and method which are capable of suppressing a reduction in an increase in coding efficiency. A receiving unit that receives an encoded bitstream including a syntax element related to an inter-image process and an analyzing unit that analyzes the syntax element received by the receiving unit in a state in which a value of the syntax element is restricted when the bitstream is a bitstream encoded based on a profile for encoding a still image are provided. For example, the present disclosure can be applied to an image processing device.
Claims14
An image processing device, comprising:
- circuitry configured to:
- receive a bitstream including a syntax element related to a number of reference pictures used for processing of a sub layer;
- analyze a value of the received syntax element related to the number of the reference pictures used for processing of the sub layer, the value being a first value different than 1 and 0 when a profile of the bitstream is a profile for encoding a moving image, and the value being restricted to 1 when a profile of the bitstream is a profile for encoding a still image which indicates that the bitstream has still image data;
- and
- decode the bitstream using the analyzed syntax element when the profile of the bitstream is the profile for encoding the still image,
- wherein the syntax element is included in a syntax of a sequence parameter set of the bitstream.
An image processing method, the method being executed via at least one processor, and comprising:
- receiving a bitstream including a syntax element related to a number of reference pictures used for processing of a sub layer;
- analyzing a value of the received syntax element related to the number of the reference pictures used for processing of the sub layer, the value being a first value different than 1 and 0 when a profile of the bitstream is a profile for encoding a moving image, and the value being restricted to 1 when a profile of the bitstream is a profile for encoding a still image which indicates that the bitstream has still image data;
- and
- decoding the bitstream using the analyzed syntax element when the profile of the bitstream is the profile for encoding the still image,
- wherein the syntax element is included in a syntax of a sequence parameter set of the bitstream.
