Abstract: A microscope system includes a light amount ratio changing unit for changing a ratio of the amount of light directed to a first optical path for directing an optical image of the sample to an eyepiece lens and a second optical path for directing an optical image of the sample to an image capturing unit, an image capturing controlling unit for controlling an exposure time of the image capturing unit, and a controlling unit for obtaining a first exposure time from the image capturing controlling unit, for calculating a second exposure time on the basis of the first exposure time and a second ratio of the amount of light, and for controlling the image capturing controlling unit to set the second exposure time as the exposure time if the light amount ratio changing unit changes to the second ratio of the amount of light.

Abstract: A camera head acquires a sample image by shooting a scaled up image of a sample obtained by a microscope body. A memory device records the sample image in a record medium. A CPU detects the completion of the sighting on an observed portion of a sample in a microscope body on the basis of a R. G. B data value of each pixel configuring a microscope image detected by the R. G. B data value. Furthermore, the CPU detects the completion of the focusing on the observed portion by the microscope boundary on the basis of the height of the contrast of the microscope image detected by the focusing completion detection unit. When both completion of the sighting and completion of focusing are detected, the CPU controls a memory device to record a sample image acquired by a camera head on a record medium.
