Abstract
Excitation light and reference light are irradiated to living body tissues, the excitation light causing the living body tissues to produce intrinsic fluorescence. The intrinsic fluorescence, which has been produced from the living body tissues when the excitation light is irradiated to the living body tissues, is detected as an intrinsic fluorescence image signal. Reflected reference light, which has been reflected from the living body tissues when the reference light is irradiated to the living body tissues, is detected as a reference light image signal. Display signals are formed from the intrinsic fluorescence image signal and the reference light image signal. Information concerning the living body tissues is displayed by utilizing the formed display signals. The display signals are formed such that an intensity of the reflected reference light is primarily reflected upon luminance, and a relative intensity of the intrinsic fluorescence is primarily reflected upon color.
