Digital microscope apparatus, method of searching for in-focus position thereof, and program
First Claim
1. An imaging control apparatus, comprising:
- a controller configured to;
calculate a provisional in-focus position based on an image by phase difference auto focus;
based on a result of a detection of the image and using the provisional in-focus position as a reference, search for an in-focus position in a predetermined range in an optical axis direction;
based on the result of the detection of the image, search for the in-focus position based on an observed surface determined using the provisional in-focus position as a reference; and
output the in-focus position.

Abstract
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.
