Digital microscope apparatus, method of searching for in-focus position thereof, and program

摘要

A digital microscope apparatus includes a first imaging unit including a first imaging device and a first optical system including an objective lens configured to enlarge first and second images of a preparation that holds a sample, the first image being formed on the first device through the first system, a second imaging unit including a second optical system that is branched from the first system and has a depth of field larger than the first system and a second imaging device on which the second image is formed through the second system, and a controller configured to calculate a provisional in-focus position of the lens based on the second image, determine an area of the first device, from which the first image is read, and search for, based on the read image, an in-focus position of the lens in a predetermined range based on the provisional in-focus position.

主权项

1. A digital microscope apparatus, comprising:
a first imaging unit including a first optical system and a first imaging device, the first optical system including an objective lens configured to enlarge first and second images of a preparation that holds a sample, the first image being formed on the first imaging device through the first optical system; a second imaging unit including a second optical system that is branched from the first optical system and has a depth of field larger than the first optical system and a second imaging device on which the second image is formed through the second optical system; and a controller configured
to calculate a provisional in-focus position of the objective lens based on the second image captured by the second imaging unit,to determine an area of the first imaging device of the first imaging unit, the first image being read from the area, andto search for, based on the first image read from the area of the first imaging device, an in-focus position of the objective lens in a predetermined range determined using the provisional in-focus position as a reference.
