Abstract: A device for picture-providing diagnosis of tissue is selectively operated in a picture-providing white light diagnosis mode and a picture providing auto-fluorescence mode. A color camera having red, green, and blue sensors provides a monitor which picture signals. A light source emits fluorescence excitation light and additionally emits so much red light that the red light remitted by the tissue dominates the red fluorescence light in the picture providing auto-fluorescence mode. The signal from the red sensor of the camera is damped so that normal time appears green and pre-malignant and early malignant tissue appears red.

Abstract: There is described a device for the picture-providing diagnosis of tissue with the selective application of two diagnosis methods, specifically an operating mode for the picture-providing white light diagnosis and an operating mode for the picture-providing auto-flourescence. The device has a light source whose light is led to the tissue via an endoscope, wherein in the endoscope there is arranged a picture transmission unit which leads the picture of the tissue to a color camera. The color camera comprises three sensors allocated to the color regions red, green and blue which are in connection with a picture processor unit which provides a monitor with the picture signals.
