1. A determination system comprising:
a first lighting unit configured to emit light so that light transmitted through a container enters an imaging device acquiring image data;
a second lighting unit configured to emit light so that light transmitted through the container does not enter the imaging device acquiring image data;
the imaging device configured to image a liquid filled in the container in an environment that an illumination condition is switched between a plurality of illumination conditions including a first state in which the first lighting unit emits light and a second state in which the second lighting unit emits light; and
a determination apparatus including at least one memory configured to store instructions and at least one processor configured to execute the instructions to divide chronological image data acquired by the imaging device into chronological image data corresponding to the illumination conditions and determine foreign matter contained in the container based on each of the chronological image data obtained by division.
