The invention relates to a method for detecting visible and infrared light using a medical imaging system, said medical imaging system comprising a camera module configured to receive a visible light signal and at least one infrared light signal from an object image. The medical imaging system for detecting visible and comprises - an input for visible light for illuminating a tissue； - an input for excitation light for exciting a fluorescence agent in the tissue； - a camera module configured to receive a visible light signal and at least one infrared light signal from an object image in the tissue. The camera module comprises at least a first, second, and third optical path for directing light from the object image to a first, second, and third filter and sensor combination respectively. In any order, the first, second, and third filters are a green filter, an infrared filter, and a red/blue patterned filter comprising red and blue filters in alternating pattern. Half of the red/blue patterned filter is a red filter and the other half is a blue filter. The green and infrared light are thus sampled at full sensor resolution, for the red and blue light spatial interpolation is required.
