Claim 6:
7. The particle size distribution measuring device according to claim 5, wherein
the light irradiating device is configured to irradiate the particle group with parallel light and further irradiate the particle group with slanting light having an optical axis slanting with respect to an optical axis of the parallel light, and
the first hardware processor discriminates whether the particle depicted in the image captured by the image capturing device is a bubble or the measurement target on the basis of at least one of a ratio, a size, a shape, a disposition, or a brightness of a light region of light and dark regions that appear as a result of refraction of the slanting light passing through the particle or at least one of a ratio, a size, a shape, a disposition, or a brightness of a dark region of the light and dark regions.
