Abstract
A general purpose device, system, and program perform colorimetric analysis by automatically comparing the color of an object to be analyzed with reference information. The device includes an imaging unit that takes images of the object to be analyzed; a memory unit that stores reference information of color information of the object in accordance with properties of the object; a conversion unit that makes the color space of the image data and the color space of the reference information the same by converting the color spaces when the color space of the image data of the object and the color space of the reference information are different; a determination unit that determines the properties of the object by comparing the color information of the image data and the color information of the reference information in a common color space; and a display unit that displays the determination results.
