    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.
