ABSTRACT:
An endoscopic system irradiates an object to be inspected and applied with a fluorescent material with visible radiation to obtain a visible radiation image of the object and with excitation radiation to obtain a fluorescent image thereof. The images thus obtained being alternately inputted into a television camera and displayed simultaneously on a display unit according to outputs from the television camera. The endoscopic system comprises an emission switch for irradiating the object alternately with the visible radiation and the excitation radiation, a first frame memory for storing the visible radiation image from the television camera, a second frame memory for storing the fluorescent image from the television camera, an image signal switch for alternately inputting the images from the television camera into the first and second frame memories, an image processing and displaying unit for processing and displaying the images from the first and second frame memories, and a central controlling portion for synchronously controlling the emission switch and the image signal switch, readout operations of the first and second frame memories, and the image processing and displaying unit to simultaneously display both the images on the display unit.
