Techniques to reduce color artifacts in a digital image |
| 摘要 |
Techniques for reducing color artifacts in a digital image are described. In one embodiment, for example, an apparatus may comprise logic, at least a portion of which is in hardware, the logic to determine a respective set of error values for each of a set of lens shading correction (LSC) tables, each set of error values describing error associated with application of its corresponding LSC table to a preprocessed image, determine a respective weight for each of the set of LSC tables based on the corresponding set of error values for that LSC table, and generate a composite LSC table for the preprocessed image as a weighted sum of the set of LSC tables, based on the respective weights for the set of LSC tables. Other embodiments are described and claimed. |

1. An apparatus, comprising:
logic, at least a portion of which is in hardware, the logic to determine a respective set of error values for each of a set of lens shading correction (LSC) tables, each set of error values describing error associated with application of its corresponding LSC table to a preprocessed image, determine a respective weight for each of the set of LSC tables based on the corresponding set of error values for that LSC table, generate a composite LSC table for the preprocessed image as a weighted sum of the set of LSC tables, based on the respective weights for the set of LSC tables, and apply the composite LSC table to the preprocessed image to generate a processed image. |
