COLOR REPRODUCING DEVICE
First Claim
1. A color reproduction device comprising color correction means for performing color conversion on an input image, which is an image of an object to be a subject shot, wherein the color correction means comprises:
- an input profile creation section which calculates an input profile using shooting characteristics of an image input device which shoots the input image and shooting-time lighting data, which is spectrum data of lighting used when shooting the input image; and
an input profile operation section which converts the input image into a device-independent color image with reference to the input profile.

Abstract
A multi-spectral camera is provided which includes an image pickup optical system which forms an image of a subject. A wavelength selecting device receives light beams from the image pickup optical system and outputs a light beam having a selected wavelength. A wavelength switching device selectively switches the selected wavelength of the wavelength selecting device. An image pickup element receives the light beam output from the wavelength selecting device and outputs image data. A spectroscope receives the light beams from the image pickup optical system and outputs spectral data. And a subject characteristic calculating unit calculates a spectral data characteristic of the subject from the spectral data output from the spectroscope.
