A method of evaluating an image, including: (a) obtaining evaluation-image data of an evaluation image to be evaluated, the evaluation-image data including coordinate-position data indicative of coordinate positions in the evaluation image and optical-characteristic-value data indicative of optical characteristic values at respective coordinate positions; (b) identifying, based on the evaluation-image data, a characteristic-value fluctuation which is a fluctuation of the optical characteristic values of the evaluation image in relation to the coordinate positions; (c) estimating, based on the evaluation-image data, an unperceivable low-frequency-fluctuation component which is one component of the characteristic-value fluctuation and which is a component that cannot be perceived due to a considerably low frequency of the fluctuation; and (d) evaluating the evaluation image based on the characteristic-value fluctuation and the unperceivable low-frequency-fluctuation component.
