ABSTRACT:
Methods and apparatuses for noise reduction include embodiments that use a weighted combination based on the presence of edges of two calculated demosaiced signals to produce a noise reduced signal. The noise reduced signal may be sharpened based on a calculated luminance of the two demosaiced signals.
