摘要

Provided is a particle group characteristic measurement device for measuring the temporal change in a particle group characteristic, which is a characteristic of a particle group comprising multiple particles distributed in a dispersing medium, said particle group characteristic measurement device comprising: an image pick-up unit which picks up an image of the particle group; a particle information extraction unit which processes the image picked up by the image pick-up unit to extract particle information, which is information on particles appearing in said picked-up image; and a particle group characteristic calculation unit which calculates a particle group characteristic at multiple points in time along a timeline, on the basis of the particle information extracted from a plurality of images all picked up since a point in time, wherein the particle group characteristic calculation unit calculates the particle group characteristic for each of the points in time on the basis of the plurality of picked-up images used to calculate the particle group characteristic at points in time preceding the same, and on the basis of the particle information extracted from the plurality of picked-up images, for which an image pick-up time period has a partial overlap.
