Original Abstract Submitted
a noise reduction circuit that performs demosaic-based noise reduction on image data. the noise reduction circuit includes a pre-demosaic circuit, a kernel calculation circuit, a noise filtering circuit, and a blending circuit. the pre-demosaic circuit generates a de-mosaiced version of an image. the kernel calculation circuit generates a denoising kernel for at least one pixel of the image and a bilateral kernel for the at least one pixel of the image using the de-mosaiced version of the image. the noise filtering circuit performs noise filtering of the image using the denoising kernel to generate a first de-noised version of the image, and performs noise filtering of the image using the bilateral kernel to generate a second de-noised version of the image. the blending circuit blends the first de-noised version with the second de-noised version to generate an output de-noised version of the image.
