1. An electronic endoscope apparatus comprising:

  • light source means for separately producing colored light having a predetermined light-wave band and monochromatic light having a plurality of different wavelengths;

    scope means for producing an image single of a biological body under examination while the biological body is irradiated by one of said colored light and monochromatic light;

    color signal processing means for processing said image signal derived from scope means so as to obtain a color television signal;

    means for converting the brightness of the color television signal acquired while said biological body is irradiated by one of said monochromatic light wave lengths to obtain a brightness-converted image signal;

    a plurality of memories, one associated with each wavelength of said monochromatic light and a color image memory for storing the calculated functional information; and

    ,calculating means for calculating a plurality of brightness-converted image signals to obtain a functional-information signal representative of functional information on said biological body.
