CELL OBSERVATION DEVICE AND CELL OBSERVATION METHOD

To provide a cell observation device allowing even an operator who has poor experience and skill, to efficiently perform work of determination of a state or quality of a cell.SOLUTION: A cell observation device comprises: observation image acquiring parts (10, 23, 24) acquiring, as an observation image, a microscopic observation image in which a cell is an observation object; a region identifying part (26) for, about a whole or a part of the observation image acquired by the observation image acquiring part, using a machine learning model for outputting an image in which two or more feature regions in the observation image, are classified, to input of the observation image, for identifying feature regions indicating respectively, two or more cell states; and image display processing parts (28, 29) for generating a region identification image in which, two or more feature regions identified by the region identifying part, are classified and drawn, in a mode in which the respective feature regions can be visually identified, and displaying in a same screen of the display part, the region identification image and the observation image.SELECTED DRAWING: Figure 1 【課題】細胞の状態や品質の判定等の作業を、経験や技量に乏しい作業者であっても効率的に行う。【解決手段】本発明に係る細胞観察装置の一態様は、細胞を対象とした顕微観察画像を観察画像として取得する観察画像取得部（１０、２３、２４）と、観察画像取得部で取得された観察画像の全体又はその一部について、観察画像の入力に対し該観察画像中の２以上の特徴領域を区分けした画像を出力する機械学習モデルを利用して、２以上の細胞状態をそれぞれ示す特徴領域を識別する領域識別部（２６）と、領域識別部により識別された２以上の特徴領域を、それぞれ視覚的に識別可能な態様で区分けして描出した領域識別画像を作成し、該領域識別画像と観察画像とを表示部の同一画面内に表示する画像表示処理部（２８、２９）と、を備える。【選択図】図１
