Abstract
Systems, articles and methods to provide lens shading color correction using block matching are disclosed. Example processor systems disclosed herein are to process at least one cluster of blocks of an image to determine at least one modification parameter, modify the first shade correction data based on the at least one modification parameter to determine second shade correction data, and correct a lens shade effect associated with the image based on the second shade correction data.
Claims25
A processor system comprising:
- memory;
- and
- processor circuitry to:
- process at least one cluster of blocks of an image to determine at least one modification parameter;
- modify first shade correction data based on the at least one modification parameter to determine second shade correction data;
- and
- correct a lens shade effect associated with the image based on the second shade correction data.
At least one non-transitory computer readable medium comprising instructions that, when executed, cause at least one processor to at least:
- process at least one cluster of blocks of an image to determine at least one modification parameter;
- access first shade correction data stored in memory;
- modify the first shade correction data based on the at least one modification parameter to determine second shade correction data;
- and
- correct a lens shade effect associated with the image based on the second shade correction data.
A system comprising:
- means for storing first shade correction data;
- and
- means for executing instructions to process an image, the executing means to:
- process at least one cluster of blocks of an image to determine at least one modification parameter;
- modify the first shade correction data based on the at least one modification parameter to determine second shade correction data;
- and
- correct a lens shade effect associated with the image based on the second shade correction data.
A method comprising:
- processing at least one cluster of blocks of an image to determine at least one modification parameter;
- accessing first shade correction data from memory;
- modifying the first shade correction data based on the at least one modification parameter to determine second shade correction data;
- and
- correcting a lens shade effect associated with the image based on the second shade correction data.
