Abstract
Provided are an image analysis method, an image analysis device, a program, and a recording medium capable of accurately estimating an image signal value of an object color-developed by using a specific coloring material by using an image signal value of a color chip. The embodiment of the present invention acquires a spectral characteristic of an object color-developed by using a specific coloring material, acquires a spectral characteristic of each of a plurality of color chips formed of coloring materials different from the specific coloring material, approximates the spectral characteristic of the object by using an approximation expression including the spectral characteristic of each of the plurality of color chips as variables, acquires an image signal value, which is obtained by imaging each of the plurality of color chips by an imaging device and which corresponds to color of a captured image, for each color chip, and estimates the image signal value, which is obtained in a case where the object is imaged by the imaging device, based on the acquired image signal value for each color chip and the approximation expression.
