1. A device comprising: a first image sensor for capturing digital images; a second image sensor synchronized with the first image sensor for capturing digital images; and at least one processor configured to generate a fused digital image by performing operations comprising: obtaining a Bayer luma image from a first digital image captured via the first image sensor; obtaining a Clear luma image from a second digital image captured via the second image sensor; generating a relational mapping based, at least in part, on a relationship between the Bayer luma image and the Clear luma image; generating difference information between Bayer luma image and the Clear luma image based, at least in part, on the relational mapping; de-noising the difference information to generate de-noised difference information; adding the de-noised difference information to the Clear luma image effective to generate a restored de-noised Bayer luma image; performing a merge evaluation using the restored de-noised Bayer luma image and a third luma image that is based, at least in part, on the Bayer luma image; and generating the fused digital image by merging the restored de-noised Bayer luma image with the third luma image using the merge evaluation.
