Abstract
An image processing device including an acquiring section configured to acquire quantization matrix parameters from an encoded stream in which the quantization matrix parameters defining a quantization matrix are set within a parameter set which is different from a sequence parameter set and a picture parameter set, a setting section configured to set, based on the quantization matrix parameters acquired by the acquiring section, a quantization matrix which is used when inversely quantizing data decoded from the encoded stream, and an inverse quantization section configured to inversely quantize the data decoded from the encoded stream using the quantization matrix set by the setting section.
Claims20
An apparatus, comprising:
- at least one processor;
- at least one memory including computer program code, the memory and the computer program code configured to, working with the at least one processor, cause the apparatus to perform at least the following:
- receive a syntax element, the syntax element indicating that a set of values comprised by a scaling list is identical to a set of values which are from a reference scaling list;
- determine the set of values which are from the reference scaling list based, at least in part on at least one of a matrix size, a prediction method, and/or a signal component.
A method comprising:
- receiving a syntax element, the syntax element indicating that a set of values comprised by a scaling list are identical to a set of values which are from a reference scaling list;
- determining the set of values which are from the reference scaling list based, at least in part on at least one of a matrix size, a prediction method, and/or a signal component.
At least one computer-readable medium encoded with instructions that, when executed by a processor, perform:
- receiving a syntax element, the syntax element indicating that a set of values comprised by a scaling list are identical to a set of values which are from a reference scaling list;
- determining the set of values which are from the reference scaling list based, at least in part on at least one of a matrix size, a prediction method, and/or a signal component.
