Suppression of clipping artifacts from color conversion

A system, comprising:

• one or more memories storing instructions;
• and
• one or more processors configured to execute the instructions to implement an image processing pipeline, wherein the image processing pipeline comprises:
• a front end module configured to receive image data that includes values associated with a first channel and not a second channel;
• and
• a color processing module configured to:
• generate intermediate values for the second channel based on the values associated with the first channel;
• receive an offset value indicating a range relative to zero;
• clip each of a first subset of the intermediate values that has a magnitude outside the range indicated by the offset value to zero to generate a clipped first subset of the intermediate values;
• add each of a second subset of the intermediate values that has a magnitude within the range and the offset value to generate a clipped second subset of the intermediate values;
• apply a correction function to the intermediate values including the clipped first and second subsets based on the offset value to determine the values for the second channel;
• and
• output the values determined for the second channel.

A non-transitory program storage device comprising instructions stored thereon to cause one or more processors to:

• receive input image data that includes values associated with a first channel and not a second channel;
• receive an offset value;
• generate intermediate values for the second channel based on the values associated with the first channel;
• clip each of a first subset of the intermediate values that has a magnitude outside a range indicated by the offset value to zero to generate a clipped first subset of the intermediate values;
• add the offset value to each of a second subset of the intermediate values that has a magnitude within the range to generate a clipped second subset of the intermediate values;
• and
• determine the values for the second channel based on the clipped first and second subsets of the intermediate values and the offset value.
