Title: Information processing device and information processing program
Inventor: OMORI MASAO
IPC: G01N21/17
Filed: 2020-03-03
Abstract: To provide a method of deriving a contact angle of a droplet with respect to a medium more easily compared with a case where a droplet is actually dropped and a laser irradiation device or the like is used.SOLUTION: A CPU 12 measures a first characteristic value indicative of shape characteristics of a surface of a medium, and computes a contact angle of a droplet with respect to the medium based on the first characteristic value. The CPU then computes the contact angle of the droplet with respect to the medium using, as the first characteristic value, a luminance statistical value obtained from a diffusion light intensity image indicative of intensity of light that is incident on the surface of the medium and reflected and diffused by the surface.SELECTED DRAWING: Figure 1
