US 2025/0054192 A1 · SUPPRESSION OF CLIPPING ARTIFACTS FROM COLOR CONVERSION

Abstract

Techniques for image processing including receiving input image data, wherein the input image data includes data associated with a clear color channel, receiving a color offset value associated with a color channel, wherein color values for the color channel are not provided in the input image data, based on the color offset value, generating intermediate estimated color values for the color channel, wherein generating the intermediate estimated color values includes: clipping color values that have a magnitude greater than the color offset value, and adjusting color values that have a magnitude less than the color offset value based on the color offset value, applying a color correction function to the intermediate estimated color values based on the color offset value to determine color corrected estimated color values, and outputting the color corrected estimated color values.

Dependent claims

A system comprising:

an image sensor configured to capture an image;
and
a processing circuit coupled to the image sensor and configurable to:
generate first and second intermediate values for a green channel in the image based on values associated with a clear channel in the image;
clip the first intermediate value having a magnitude outside of a range to generate a first clipped value;
add an offset value to the second intermediate value having a magnitude within the range to generate a second clipped value;
and
apply a correction function to the first and second clipped values based on the offset value to determine values for the green channel.
