Title:
SPECIMEN OBSERVATION APPARATUS AND SPECIMEN OBSERVATION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/171419
Kind Code:
A1
Abstract:
The present invention provides a technology whereby relative positioning in the horizontal direction between a specimen observation area in a specimen container and an imaging field of view can be reliably performed, even prior to adjusting the focal position in the vertical direction using an auto-focus system. This specimen observation apparatus: obtains a luminance value for an image at a plurality of locations in the specimen container, prior to performing auto-focus; and uses the number of high-luminance regions and the width of those regions and identifies a central position, in the horizontal direction, in the specimen container or uses the number of low-luminance regions and the width of those regions and identifies the central position, in the horizontal direction, in the specimen container (See Fig. 1).
