    摘要： 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.

    摘要： In an image processing apparatus, an image processing method, a program, and a recording medium, a first image signal corresponding to a spectral sensitivity and a second image signal that corresponds to the spectral sensitivity and that has at least one spectral sensitivity different from the first image signal are acquired from an image signal of a captured image of a measurement sheet. The first image signal is set as a third image signal, or the third image signal is generated by calculating a total of two or more first image signals for each pixel. The second image signal is set as a fourth image signal, or the fourth image signal is generated by calculating a total of two or more second image signals for each pixel. A fifth image signal is generated by calculating a ratio between the third image signal and the fourth image signal for each pixel, and a surface distribution of an external energy amount applied to the measurement sheet is derived based on the fifth image signal.
