DIGITAL MICROSCOPE APPARATUS, FOCUSING POSITION SEARCHING METHOD THEREFOR, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a digital microscope apparatus that can process focusing at high speed and with high accuracy.SOLUTION: A digital microscope apparatus comprises a first imaging unit having a first optical system including an object lens that enlarges the image of a preparation slide holding an observation object and a first imaging element on which an image is formed through the first optical system; a second imaging unit having a second optical system, which is branched out of the first optical system and is greater in field depth than the first optical system, and a second imaging element on which an image is formed through the second optical system; and a control unit that calculates a tentative focusing position of the object lens on the basis of the image shot by the second imaging unit, determines an area in which an image is read out of the first imaging element of the first imaging unit, and searches a prescribed range with reference to the tentative focusing position for a focusing position of the object lens on the basis of the image read out of the first imaging element.
