Title:
IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/014756
Kind Code:
A1
Abstract:
Disclosed is an imaging device that uses images from a plurality of different points in time to determine, with high precision, the suspension/attachment state of cells in a culture solution in a culture vessel. Said imaging device (1) is provided with: a vessel-gripping unit (32) that grips a culture vessel (S) containing cells and a culture solution; an oscillation unit (60) on which the vessel-gripping unit (32) is provided; a vibration unit (50) that vibrates the oscillation unit (60); an imaging unit (10) that takes images of the cells inside the culture vessel (S); an image-correction unit (4) that uses images that the imaging unit (10) has taken of a plurality of imaging sites, including at least one mid-vibration image, to correct inter-image offsets due to the fact that the imaging sites are different; and an image-processing unit (5) that uses the images taken by the imaging unit (10) and the images corrected by the image-correction unit (4) to determine the suspension state or attachment state of cells. This configuration prevents attached cells from being mistakenly determined to be suspended and distinguishes between a state in which cells are locally attached and a completely-attached state.
