Abstract
An evaluating method includes obtaining, by an imaging device, a two-dimensional reflected light amount distribution of a surface of a target; classifying, by one or more processors, the surface into a plurality of areas on the basis of chromaticity information of the two-dimensional reflected light amount distribution; and evaluating, by one or more processors, appearance characteristics of the target on the basis of respective sets of chromaticity information of the areas.
