Abstract
A processing unit (PU) is configured to generate reference values based on previously displayed frames in order to decode encoded frames having one or more noise-based effects. To this end, the PU includes a noise effect circuitry configured to determine noise values associated with a previously displayed frame. The noise effect circuitry then subtracts respective noise values from the pixel values of the previously displayed frame to determine reference values for decoding an encoded frame. Further, the PU includes a decoder that decodes the encoded frame based on the determined reference values.
Claims20
A processing unit (PU), comprising:
- a noise effect circuitry configured to generate a plurality of reference values based on a plurality of noise values associated with a previously displayed display frame with a noise-based effect;
- and
- a decoder configured to decode an encoded frame based on the plurality of reference values to produce a second display frame.
A processing system, comprising:
- a memory;
- and
- an PU coupled to the memory and configured to:
- generate a plurality of reference values based on a plurality of noise values associated with a previously displayed display frame with a noise-based effect;
- and
- decode an encoded frame based on the plurality of reference values to produce a second display frame.
A method, comprising:
- generating a plurality of reference values based on a plurality of noise values associated with a previously displayed display frame with a noise-based effect;
- and
- decoding an encoded frame based on the plurality of reference values to produce a second display frame.
