ALEXANDRIA, Va., July 30 -- United States Patent no. 12,373,986, issued on July 29, was assigned to NVIDIA Corp. (Santa Clara, Calif.).
"Shading calibration for radial sensor lenses" was invented by Yongshen Ni (San Jose, Calif.) and Eric Dujardin (San Jose, Calif.).
According to the abstract* released by the U.S. Patent & Trademark Office: "In various examples, systems and methods for calibration for sensor lens shading using non-radial correction of residual radial shading error are provided. In some embodiments, a calibration flow includes computation of calibration parameters corresponding to radial lens shading correction, and computation of calibration parameters corresponding to non-radial lens shading correction. A lens shading pr...
