Fecha de publicación: 05/01/2023 Fuente: WIPO (eseential oils OR extracts) Provided is a particle analysis apparatus that analyzes particle characteristics on the basis of an original image obtained by imaging a particle or a particle group, for providing a particle image analysis apparatus capable of acquiring information from an individual particle image not only for particles with high appearing frequency but also for particles with low appearing frequency while suppressing data capacity required to save the individual particle image. The particle analysis apparatus includes: an individual particle image generation unit 52 that extracts an individual particle from the original image and generates an individual particle image PI; a particle characteristic calculation unit 54 that calculates one or a plurality of types of particle characteristics of a particle in the individual particle image PI on the basis of the individual particle image PI; a classification unit 56 that classifies, with regard to a plurality of classes prescribed by part or all of one or the plurality of types of particle characteristics, the particle into a corresponding class of the calculated particle characteristic; and an individual particle image preservation unit 57 that is configured to save the individual particle image PI of the particle belonging to each class in a storage S in the number equal to or lower than a saving upper limit set to each of the plurality of classes.
