Abstract
The present disclosure relates to an image processing device and method for enabling suppression of an increase in encoding load. An encoding mode of encoding of an image is set by setting a transform type with a minimum encoding cost in a non-joint chrominance encoding mode as a transform type in a joint chrominance encoding mode, and deriving an encoding cost in the joint chrominance encoding mode. The present disclosure can be applied to, for example, an image processing device, an image encoding device, an information processing device, an electronic device, an image processing method, an information processing method, or the like.
Claims14
An image processing device comprising:
- circuitry configured to set an encoding mode of encoding of an image by
- setting a transform type with a minimum encoding cost in a non-joint chrominance encoding mode as a transform type in a joint chrominance encoding mode, and
- deriving an encoding cost in the joint chrominance encoding mode, wherein the circuitry is configured to
- compare the minimum encoding cost of the non-joint chrominance encoding mode with the encoding cost of the joint chrominance encoding mode, and
- select a mode with the minimum encoding cost.
An image processing method comprising:
- setting an encoding mode of encoding of an image by
- setting a transform type with a minimum encoding cost in a non-joint chrominance encoding mode as a transform type in a joint chrominance encoding mode, and
- deriving an encoding cost in the joint chrominance encoding mode;
- comparing the minimum encoding cost of the non-joint chrominance encoding mode with the encoding cost of the joint chrominance encoding mode;
- and
- selecting a mode with the minimum encoding cost.
An image processing device comprising:
- circuitry configured to set an encoding mode of encoding of an image by
- setting a transform type with a minimum encoding cost in a non-joint chrominance encoding mode as a transform type in a joint chrominance encoding mode, and
- deriving an encoding cost in the joint chrominance encoding mode, wherein the circuitry is configured to
- in the non-joint chrominance encoding mode, derive an encoding cost of each transform type, and set the transform type with the minimum encoding cost among the derived encoding costs, and
- sets the set transform type with the minimum encoding cost in the non-joint chrominance encoding mode as the transform type in the joint chrominance encoding mode.
