Provided is an image processing method comprising: obtaining first, second and third image planes from at least one image sensor, the first image plane formed from light of a first spectral distribution, the second image plane formed from light of a second spectral distribution and the third image plane formed from light of a spectral distribution which substantially covers the visible spectrum; generating first spatial frequency components from the first, second and third image planes; generating a second spatial frequency component from the third image plane; applying a color transform to the first spatial frequency components from the first, second and third image planes to obtain at least first, second and third transformed first spatial frequency image planes; combining the at least first, second and third transformed first spatial frequency image planes with the second spatial frequency component from the third image plane to form an image.
