Abstract
A photomicroscopy system includes a microscope unit which outputs an enlarged image of a subject as a light flux, an image capturing unit which forms an image of the light flux output by the microscope unit and converts the formed image into digital data, a sensitivity changing unit which changes a sensitivity of the image capturing unit, and a computing unit which obtains an exposure time by using the digital data captured by the image capturing unit in a state where the sensitivity is increased to the high sensitivity after instructing the sensitivity changing unit to increase the sensitivity of the image capturing unit to the high sensitivity while calculating the exposure time for obtaining a suitable brightness by the image capturing unit, and sets the sensitivity of the image capturing unit to a low sensitivity after the exposure time is set in the image capturing unit.
