Patent ID: 8836795

Claim:
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 =( I 1 ( x, y ), I 2 ( x, y ), I 3 ( x, y ), . . . , I n ( x, y )) wherein n is an integer, each of I 1 (x, y), I 2 (x, y), I 3 (x, y), . . . , and I n (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, I 1 (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 I 1 (x, y).
