Publication number: 20130064448Abstract: An embodiment of a method for reducing chroma noise in digital image data and of a corresponding image processor. Chrominance components are subjected to low-pass filtering. The strength of the low-pass filtering is modulated in accordance with the dynamic range of the luminance signal and the dynamic range of each of the two chrominance signals in order to avoid color bleeding at image-object edges. Moreover, the low-pass filtering is selectively applied to pixels with similar luminance and chrominance values only. A combination of down-sampling and up-sampling units is employed so that comparatively small filter kernels may be used for removing chroma noise with low spatial frequency.Type: ApplicationFiled: September 10, 2012Publication date: March 14, 2013Applicants: STMicroelectronics (Grenoble 2) SAS, STMicroelectronics S.r.I.Inventors: Valeria TOMASELLI, Mirko GUARNERA, Gregory ROFFET
