First Claim
1. Endoscope equipment consisting of an illuminating means to irradiate in time series the light separated into multiple wavelength regions to illuminate a subject, image pickup element to receive the light reflected from the subject and convert it into electrical signals, light receiving element having the same characteristics as the image pickup element to receive the light separated into multiple wavelength regions and convert it into electrical signals, correcting means to control the electrical signals from the aforementioned image pickup element on basis of the electrical signals obtained at the light receiving element and correct the spectral characteristics, signal processing means to process the electrical signals corrected by the correcting means for each wavelength regions and produce the signals for screen display, and display means to display the picture in each wavelength region using the signals from the signal processing means and by means of a particular color signal and display are spectral waveform.

Abstract
The endoscope equipment of this invention is to display on the monitor screen pictures of different wavelength regions with particular color signals and the synthesized picture and spectral analysis waveforms at particular points by sequentially irradiating the light of a specified wavelength region to a subject, receiving the image of the reflected light with the image pickup element, converting it into electrical signals, conducting spectral characteristic correction on the obtained signals, and then by processing the signals for each wavelength region.
