Generating full color images by demosaicing noise removed pixels from images

摘要

A method and apparatus to remove color noise included in raw data while effectively preventing image quality degradation. For interest pixels serially set onto a mosaic image formed of raw data, conversion is executed into a pixel value for noise removal based on a processing reference pixel value having a unified color signal component in each interest pixel, noise is removed from the pixel value for noise removal, and the pixel value for noise removal with noise removed is converted into the source pixel value, whereby only color noise can be removed without affecting a luminance signal.
