Abstract: A discrimination device is a device that discriminates whether or not a discrimination target object is a blood cell based on an image of the discrimination target object, and includes a blood cell feature extraction unit that acquires an image of a blood cell and extracts a feature of the blood cell from the acquired image, a discrimination target object feature extraction unit that acquires the image of the discrimination target object and extracts a feature of the discrimination target object from the acquired image, and a discrimination unit that discriminates whether or not the discrimination target object is a blood cell through anomaly detection based on the extracted feature of the blood cell and the feature of the discrimination target object.

Abstract: A cell observation system observes a cell moving in a flow path with a fluid, and includes a first imaging apparatus, a second imaging apparatus, and a control device. The first imaging apparatus includes a first optical system and a first imaging element, and captures an image of the cell at a first position in a moving direction. The second imaging apparatus includes a second optical system, in which a focus is adjusted based on a focus adjustment signal, and a second imaging element, and captures an image of the cell at a second position downstream of the first position. The control device obtains a passing position of the cell in a cross section of the flow path based on the image obtained by the first imaging element, generates the focus adjustment signal, and provides the signal to the second optical system.

Abstract: A cell observation system observes a cell moving in a flow path with a fluid, and includes a first observation apparatus, a second observation apparatus, and a control device. The first observation apparatus includes an objective lens and a line camera. The second observation apparatus includes an objective lens and an area camera. The control device analyzes first imaging data output from the first observation apparatus to determine whether the cell satisfies a specific condition, instructs the area camera to output second imaging data of the cell determined to satisfy the specific condition, and analyzes the second imaging data output from the second observation apparatus to determine whether the cell is a specific cell.

Abstract: An image acquisition apparatus includes a spatial light modulator, an optical scanner, a detection unit, a control unit. The spatial light modulator performs focused irradiation on irradiation regions on a surface or inside of an observation object with modulated excitation light. The detection unit has imaging regions in an imaging relation with the irradiation regions on a light receiving surface, each of the imaging regions corresponds to one or two or more pixels, and a pixel that corresponds to none of the imaging regions exists adjacent to each imaging region. The control unit corrects a detection signal of a pixel corresponding to each imaging region on the basis of a detection signal of the pixel that exists adjacent to the imaging region and corresponds to none of the imaging regions, and generates an image of the observation object on the basis of the corrected detection signal.

Abstract: A method and apparatus for measuring enzyme activity by supplying a substrate solution and an enzyme solution into a reaction vessel combined with a total reflection absorption prism is disclosed. A measurement solution (40) in which the enzyme solution and the substrate solution are combined together is kept at a constant temperature within the reaction vessel (26) by a temperature control unit (23), and is stirred by a stirrer (21). Infrared light (36) emitted from an infrared light source (3) is made incident on the interface between a total reflection absorption prism (28) disposed in contact with the measurement solution (40) and the measurement solution (40) from the side of the total reflection absorption prism (28) and is totally reflected by the interface. The spectrum of transmitted infrared light (37) thus totally reflected and emitted is detected by an infrared light detector (5).
