Abstract
Provided are an analysis evaluation method and device, and a computer program for the state of a subject surface in a still image. The method includes: a step of acquiring color information of each pixel in a predetermined region in a still image, a step of calculating a numerical value indicating a diversity of color from the acquired color information, a step of calculating an average value of the color information, and a step of calculating a coefficient of variation on the basis of the calculated numerical value indicating the diversity of color and the calculated average value of the color information. Herein, the coefficient of variation is used as an index for evaluating the surface state of an object.
