A droplet measurement system, etc. is provided that is capable of measuring the volume of a droplet with high precision by means of image processing with a lighter arithmetic load than before. The droplet measurement system is a droplet measurement system that measures the volume of a droplet dripping from a nozzle being provided with: an imaging unit that images an object to be imaged and outputs image data, wherein the imaging unit is placed such that a field of view is directed to a tip of the nozzle and a region extending vertically downward from the tip； an imaging control unit that sets the field of view of the imaging unit to a rectangular region long in a vertical direction and that causes the imaging unit to execute imaging； and an image processing unit that: acquires a plurality of images, in a temporal sequence order, that correspond to the rectangular region and that have captured therein the tip of the nozzle and the region extending vertically downward from the tip based on the image data output from the imaging unit； and that calculates the volume of the droplet based on the images acquired in a temporal sequence order.
