FIELD: physics.
SUBSTANCE: system has a plurality of light sources which can illuminate an object, in which at least a portion of the light sources can emit light having wavelength in a different wavelength range; a control unit which can control the plurality of light sources such that the plurality of light sources illuminates an object in a successive number of illumination periods, wherein in at least two of the successive illumination periods, the object is illuminated with wavelengths in a different wavelength range; an obtaining unit which can obtain at least four groups of object image data in at least two illumination periods; and a reconstruction unit which can reconstruct the at least four obtained groups of image data into a group of image data of at least a four-dimensional colour space.
EFFECT: improved image quality.
