Patent Images
1. An electronic endoscope apparatus comprising:
- a light source that illuminates a subject with white light;
a color imaging device that takes an image of the subject illuminated with white light; and
a spectral-image forming circuit that operates RGB three color image signals based on an output from the color imaging device and a matrix data to generate a spectral image signal representative of a spectral image in a color at a designated wavelength, wherein the spectral-image forming circuit is adapted to generate spectral image signals representative of spectral images in respective colors of at least three wavelengths different from one another;
wherein the spectral-image forming circuit is adapted to be capable of generating another spectral-image signal representative of another spectral image in a fixed color so as to selectively output either (i) the spectral image signal representative of the spectral image in the fixed color or (ii) the spectral image signal representative of the spectral image in the color of the designated wavelength.
