Claim 9:
10. A non-transitory computer-readable storage medium storing a program for a particle size distribution measuring device, the program causing a computer to execute the steps of:
receiving, from an image capturing device that captures light on an opposite side of a particle group from a light source, image data such that light from the light source passes through translucent particles in the particle group before reaching the image capturing device, and depictions of the translucent particles in the image have light and dark regions resulting from refraction of the light passing through the translucent particles;
determining a difference in light and dark regions in a depiction of a particle depicted in the image, the light and dark regions being a result of refraction of light passing through the particle; and
discriminating whether the particle depicted in the image is a first translucent particle or a second translucent particle based on the difference in the light and dark regions that appear in the depiction of the particle in the image.
