A medical camera comprising a housing (10) having a light source (55), optics (22, 28, 34, 80) and an imager (8), the housing (10) having an entrance window (16) for from an examination area having return-running observation light, which can not be achieved directly by light emitted from the light source, wherein the light source (55) is a UV light source, wherein the entrance window is formed as a filter or in the beam path between the entrance window (16) and the image converter (8 a filter (59; 84) is arranged, and wherein the image converter (8) is a color-sensitive image converter, characterized in that the UV light source (55) is operated in a clocked manner and a clock generator (72) in addition to first activation pulses for driving serve the UV light source (55), provides control pulses which are out of phase with the first clock pulses and that the first clock pulses and the control pulses to a computer circuit (74) given who the one cooperating with an integrating image memory (76), wherein the arithmetic circuit (74) adds the output signal of the image converter (8) to the content of the image memory (76) upon receipt of a first clock signal while receiving the control signal from the image converter (8) extracts the provided image from the integrated image held in the image memory (76). |
