1. A virtual microscope system for capturing a stained sample to estimate a spectrum, comprising: an image obtaining unit for obtaining a stained sample image of one or more bands of the stained sample; a spectrum obtaining unit for obtaining a spectrum at one or more predetermined portions of the stained sample image; an optical path setting unit for setting an optical path of a light flux passed through the stained sample, with respect to the image obtaining unit and the spectrum obtaining unit, so that the spectrum of the stained sample image can be obtained by the spectrum obtaining unit each time the image obtaining unit obtains the stained sample image; and a control unit for controlling, in two or more observation fields of the stained sample, to repeat obtaining the stained sample image by the image obtaining unit and obtaining the spectrum of the stained sample image by the spectrum obtaining unit so that a virtual slide and a spectrum table of the stained sample are created.
