Claim:
1. A non-transitory program storage device comprising instructions stored thereon to cause one or more processors to: receive signals from an imager; process the signals received from the imager; separate at least one of the processed signals into a plurality of bands; apply noise reduction to all bands below a first frequency, wherein the instructions to apply comprise instructions to utilize an estimated noise level from a noise model, and wherein the noise model is locally-adaptive and estimates an overall gain level for pixels in the received signals based, at least in part, on one or more of the following: lens shading compensation gains for the respective pixels, local tone mapping curve data for the respective pixels, and image fusion strength information for the respective pixels; sharpen all bands below the first frequency; and sum all of the bands to produce an enhanced image signal.
