Most common cameras use a CCD or CMOS sensor device measuring a single color per pixel. Demosaicking is the interpolation process by which the two missing color values are estimated. The demosaicking is usually performed by combining close values from the same channel or the other two. As a result, the noise, being almost white at the sensor, gets color and spatial correlated. The rest of the imaging chain, consisting mainly in color and gamma corrections and compression, enhances the noise in dark parts of the image leading to contrasted colored spots of several pixels. The size of these spots depends on the applied demosaicking method. The inversion of the transfer function is not able to revert all noise correlating stages. For this reason, we will perform denoising and HDR fusion in the RAW domain. HDR methods using the weighted average (1) actually reduce noise, but this reduction is rather minor due to the small number of values being involved.
