An endoscope system includes an endoscope and a control device. The endoscope includes an illumination optical system with a fluorescent body formed in an optical path and an imaging optical system with an imaging element outputting an imaging signal of an optical image. The control device includes a light source unit which supplies an excitation light to the illumination optical system so as to emit light from the fluorescent body and an image processing section which corrects the imaging signal output from the imaging element. The image processing section includes: an illumination light spectrum calculating unit, a chromaticity correction table creating unit and an image correcting unit.

The present application claims priority from Japanese Patent Application No. 2009-219243 filed on Sep. 24, 2009 and Japanese Patent Application No. 2010-119747 filed on May 25, 2010, the entire content of which is incorporated herein by reference.
1. Field of the Invention
The present invention relates to an endoscope system.
FIG. 1 is a diagram illustrating an embodiment of the invention, and is a block diagram illustrating an endoscope system;
FIG. 2 is an external view of an example of the endoscope system shown in FIG. 1;
FIG. 3 is a graph showing a light emission spectrum of a violet laser light emitted from a violet laser light source, a blue laser light emitted from a blue laser light source, and the blue laser light having a wavelength converted by a fluorescent body;
Hereinafter, an embodiment of the invention will be described with reference to the accompanying drawings.
FIG. 1 is a diagram illustrating an embodiment of the invention, and is a conceptual block diagram illustrating an endoscope system. FIG. 2 is an external view of an example of the endoscope system shown in FIG. 1.
As shown in FIGS. 1 and 2, an endoscope system 100 includes an endoscope 11, and a control device 13 to which the endoscope 11 is connected. The control device 13 is connected to a display unit 15 which displays image information or the like, and an input unit 17 which receives an input operation. The endoscope 11 is an electronic endoscope which includes an illumination optical system emitting an illumination light from a front end of an endoscope insertion unit 19 and an imaging optical system including an imaging element 21 (refer to FIG. 1) configured to capture an image of an observation area.
