Disclosed is an image capturing device provided with an irradiation unit, an image capturing unit, and a color representation setting unit. The irradiation unit irradiates a subject with infrared rays having different wavelength intensity distributions, the image capturing unit captures images of the subject by the respective infrared rays being reflected by the subject and forming image information indicating the respective images, and the color representation setting unit sets color representation information for representing the respective images, which are indicated by the formed image information, by different plain colors. Also disclosed is an image capturing method for separating infrared rays from a subject into infrared rays having different wavelength intensity distributions, capturing images of the subject by the respective infrared rays having different wavelength intensity distributions, forming image information indicating the respective images, and representing the respective images, which are indicated by the formed image information, by different plain colors. |

1. An image capturing device comprising:
an irradiating part, a capturing part, and a color setting part; wherein the irradiating part irradiates plurality of infrared beams onto an object, each of the plurality of the infrared beams having different wavelength intensity distributions each other; the capturing part captures an image of the object using each of a plurality of reflected infrared beams having different wavelength intensity distributions, each of the plurality of the reflected infrared beams being reflected by the object, and forms image data which represent a plurality of images for the each of the plurality of the reflected infrared beams; and the color setting part sets color data for coloring each of the plurality of the images represented by the image data by using different mono-colors, wherein when the image data is denoted by |C>, the following equations hold;
|C>=H|I>, |C>=(R, G, B),|I>T=(I1(x, y), I2(x, y), I3(x, y), . . . , In(x, y)) wherein n is an integer, each of I1(x, y), I2(x, y), I3(x, y), . . . , and In(x, y) is the image data representing the each of the plurality of the images captured by the capturing part, (x, y) is a position in the each of the plurality of the images, H denotes the color data expressed in a matrix of three rows and n columns, and R, G, and B respectively denote luminosity of “R”, “G”, and “B” components in three primary colors, I1(x, y) is captured using the reflected infrared beam having a wavelength intensity distribution located at a shortest wavelength side among the plurality of the reflected infrared beams, and H is selected so that R depends mainly on I1(x, y). |
