Abstract
A color component predictive method determines a base color component and uses the base color component to compute offsets for other color components. The block is then able to be coded using the base color component and the offsets of the other color components. For decoding, the base color component is used with the offsets to regenerate the other color components.
Claims22
A method of image coding programmed in a memory of a device comprising:
- a. determining a color component as a base color component;
- b. calculating one or more offsets using the base color component;
- c. coding the base color component independently;
- and
- d. coding the one or more offsets.
A method of image decoding programmed in a memory of a device comprising:
- a. receiving a base color component and offsets;
- and
- b. reconstructing one or more color components using the base color component and the offsets.
A system programmed in a controller of a device comprising:
- a. a base module for determining a color component as a base color component;
- b. a calculation module for calculating one or more offsets using the base color component;
- and
- c. a coding module for coding the base color component independently and coding the one or more offsets.
An apparatus comprising:
- a. an image acquisition component for acquiring an image;
- b. a memory for storing an application, the application for:
- i. determining a color component as a base color component of the image;
- ii. calculating one or more offsets using the base color component;
- iii. coding the base color component independently;
- and
- iv. coding the one or more offsets;
- and
- c. a processing component coupled to the memory, the processing component configured for processing the application.
