Claim:
1. A digital microscope apparatus, comprising: an illumination optical system configured to emit illumination light; a stage having an opening capable of transmitting the illumination light therethrough, on which a preparation is allowed to be placed in accordance with a position of the opening; an enlarging imaging unit including an objective lens that is configured to enlarge an image and is disposed so as to face the illumination optical system with the stage disposed therebetween and an imaging device configured to capture an image enlarged by the objective lens; a white image acquiring unit configured to: open the opening of the stage, cause the illumination optical system to emit the illumination light in a state where an image point of the illumination optical system is aligned with a focal point of the objective lens of the enlarging imaging unit, and acquire, as a white image, an image formed on an imaging surface of the imaging device of the enlarging imaging unit; a calculation unit configured to use the captured white image to calculate a shading correction coefficient; and an adjustment unit configured to adjust a position of the illumination optical system in an optical axis direction, wherein the adjustment unit performs the adjustment by moving the position of the illumination optical system in a state where the preparation is placed on the stage to a side of the stage by a predetermined distance.
