Patent ID: 10983039

Abstract:
In the present invention, information is analyzed, the positional relationship of cells/microbes in the optical axis direction is detected, and motility of cells/microbes is evaluated even in an out-of-focus view from an image obtained by a single image capture in an observation view of the cells/microbes. The present invention is provided with an optical system used to measure microparticles present in a sample liquid in a sample container, a drive mechanism for driving the sample container and/or a portion of the optical system in order to three-dimensionally search a bottom surface of the sample container, a control unit for controlling the optical system or the drive mechanism, an image processing unit for dividing an image of microparticles in the sample container at a first time and a second time into an in-focus region and an out-of-focus region and acquiring information relating to the microparticles, and a display unit for displaying the information relating to the microparticles as information representing a temporal change between the first time and the second time.
