Abstract: A surface performance evaluation device including memory and a processor coupled to the memory. The processor being configured to: acquire a captured image, which is a moving image of a test object on which a liquid is dispersed, and which is captured by a camera; quantify, based on the captured image that is acquired by the processor, a degree of diffusion of the liquid that is dispersed on the test object and diffuses; and evaluate a surface performance of the test object based on an index quantified by the processor.
