Patent ID: 8040373

Claim:
An endoscope system apparatus comprising: an endoscope comprising an imaging element; a signal processor that forms a color image of an object based on an output from the imaging element, the signal processor comprising an information-outputting circuit that outputs each of spectroscopic characteristic information along with a data of the color image, a first storing portion that stores matrix data of a plurality of wavelength regions for forming the spectral image based on the data of the color image, and a first spectral image-forming circuit that performs a matrix operation based on the data of the color image and the matrix data of the plurality of wavelength regions stored in the first storing portion so as to form the spectral image with respect to a selected wavelength region, wherein the spectroscopic characteristic information is for forming a spectral image of the object and includes a spectroscopic characteristic of the imaging element; and an image recording apparatus that records the color image output from the signal processor, wherein the image recording apparatus is constituted separately from the signal processor and comprises: a second storing portion that stores matrix data of a plurality of wavelength regions for forming the spectral image based on the data of the color image, the matrix data of the plurality of wavelength regions corresponding to each of the spectroscopic characteristic information output from the information-outputting circuit; and a second spectral image-forming circuit that performs a matrix operation based on the data of the color image and the matrix data of the plurality of wavelength regions stored in the second storing portion so as to form the spectral image with respect to a wavelength region.
