    • According to a method of and apparatus for displaying as an autofluorescent-light image emitted from a target subject upon the irradiation thereof by a excitation light, even for cases in which a malfunction of the apparatus occurs that prevents an operator from obtaining a desired image, a standard-image is displayed so as to enable an operator to safely and expediently remove the insertion portion of the endoscope from the body of a patient, whereby the safety of the patient can be ensured. When an irregularity in the temperature of one of the light sources, the operation of one of the drive apparatus, or other cause of an operational irregularity occurring in of one of the light sources is detected by the semiconductor-laser temperature detecting means, the reference-light source temperature detecting means, or the emission-output detecting means, in response to a detection signal thereof, the standard-image display mode is switched to automatically.

    • An accurate determination of the tissue state of a diseased portion is performed by use of an image obtaining apparatus employing a charge multiplying type solid state image obtaining element. A target subject is irradiated with an illuminating light that contains an excitation light, and the reflected light, which includes a fluorescence image, reflected from the target subject thereupon is detected by a charge multiplying type CCD. At this time, the fluorescent light image is passed through a rotating filter, and is detected as a wide band fluorescent light image and a narrow band fluorescent light image by the charge multiplying type CCD, and obtained as a wide band fluorescence image data and a narrow band fluorescence image data by an image processing unit. A fluorescence diagnostic image is obtained of the wide band fluorescence image data and the narrow band fluorescence image data, and displayed on a monitor.
