Noise reduction filter processing circuit, image processing circuit, imaging device, and storage medium storing noise reduction program |
摘要 |
A noise reduction filter processing circuit includes a first operating part calculating first saturation information indicative of a saturation of an input image, a nonlinear processing part performing nonlinear processing on the input image, a second operating part calculating second saturation information indicative of a saturation of the input image subjected to the nonlinear processing, and a correction operating part performing a correction operation on the input image subjected to the nonlinear processing using the first saturation information and the second saturation information.
