Microscope system

A microscope system comprising:

• an optical system holding member that holds a plurality of optical systems with different magnifying powers and inserts one optical system among the plurality of optical systems at an optical path;
• an image-capturing element that captures an image of a specimen formed by the optical system and outputs an image signal;
• an input device through which a specific value for a magnification factor at which the specimen image is to be magnified is input;
• an arithmetic operation device that calculates an electronic zoom magnification factor for the specimen image by ascertaining the magnifying power of the optical system inserted at the optical path based upon the specific value input through the input device and the magnifying power of the optical system having been ascertained;
• and
• a control device that generates a specimen image at a display magnification factor by using the image signal output from the image-capturing element based upon the electronic zoom magnification factor calculated by the arithmetic operation device.

A microscope comprising:

• a mounting unit at which an image-capturing device is mounted;
• an optical system holding member that holds a plurality of optical systems with different magnifying powers and inserts one optical system among the plurality of optical systems at an optical path;
• an input device through which a specific value for a display magnification factor at which a specimen image is to be displayed is input;
• an arithmetic operation device that calculates an electronic zoom magnification factor for the specimen image based upon the specific value input through the input device and the magnifying power of the optical system inserted at the optical path to form the specimen image on the image capturing device;
• and
• a control device that generates a specimen image at the display magnification factor that has been input by using the image signal output from the image-capturing device based upon the electronic zoom magnification factor calculated by the arithmetic operation device.

A microscope comprising:

• a mounting unit at which an image-capturing device is mounted;
• an inserting device that inserts one optical system among a plurality of optical systems with different magnifying powers for forming a specimen image on the image-capturing device at an optical path;
• an input device through which a specific value for a display magnification factor at which the specimen image is to be displayed is input;
• an arithmetic operation device that selects one of the plurality of optical systems based upon the specific value input through the input device and calculates an electronic zoom magnification factor for the specimen image based upon the magnifying power of the optical system having been selected and the specific value having been input;
• and
• a control device that controls the inserting device so as to allow the selected optical system to be inserted at the optical path and generates a specimen image at the display magnification factor by using an image signal output from the image-capturing device, based upon the electronic zoom magnification factor calculated by the arithmetic operation device.

An image capturing method adopted in a microscope that displays a specimen image at a display magnification factor achieved based upon an optical magnification factor of an optical system and an electronic zoom magnification factor set for an image-capturing device, comprising:

• obtaining the display magnification factor;
• selecting the optical system to be utilized based upon the display magnification factor that has been obtained;
• calculating the electronic zoom magnification factor based upon the optical magnification factor of the optical system having been selected and the display magnification factor having been obtained;
• and
• generating a specimen image at the display magnification factor having been obtained by using an image signal constituting the specimen image output from the image-capturing element.
