A method and an imaging system is described for providing a low noise color image. The method comprises the steps of: exposing an image sensor to visible spectral energy and non-visible spectral energy, said image sensor comprising pixels for obtaining first image data associated with said visible spectral energy and pixels for obtaining second image data associated with said non-visible spectral energy; generating first and second image data; subjecting said first image data to a low-pass filt and said second image data to a high-pass filter; and, forming a color image by adding at least part of the high frequency components of said second image data to at least part of the low frequency components of said first image data. |
