- 摘要：
PROBLEM TO BE SOLVED: To obtain a proper spectroscopic image constantly regardless of the kinds of patients and the types of electronic endoscopes.
SOLUTION: A processor 11 of the electronic endoscope system 2 has a spectroscopic image generation part 31 which generates spectroscopic images with desired wavelength ranges from image pickup signals obtained by a CCD 21. The spectroscopic image generation part 31 comprises a calculation circuit 40 which determines the average spectroscopic characteristics of all pixels of an estimated spectroscopic image to make spectroscopic characteristics Sr representing the shade of color as a whole of the estimated spectroscopic image, an emphasis processing circuit 41 which carries out an emphasis processing for the respective pixels of the estimated spectroscopic image according to the difference between the spectroscopic characteristics of the respective pixels of the estimated spectroscopic image and the representative spectroscopic characteristics Sr obtained with the calculation circuit 40, a degree of emphasis adjustment circuit 42 which adjusts the degree of emphasis for the emphasis processing so as to hold the intensity of the spectroscopic characteristics of the respective pixels of the estimated spectroscopic image after the emphasis processing within a previously prescribed range and a channel allotment circuit 43 which allots spectral images in three arbitrary wavelengths of the estimated spectroscopic image after the emphasis processing to preset three channels of RGB.
