A medical-endoscopic instrument includes a distal elongate insertion section (), for the minimal-invasive introduction into a human or animal body, with a first LED (), a second LED () and a picture sensor (). The first LED includes a first light spectrum (), suitable for fluorescence endoscopy. The second LED includes a second light spectrum (), suitable for white light endoscopy. A light filter (), arranged in front of the second LED in the viewing direction (x), has a transmission spectrum (). The second LED is configured to irradiate according to the second light spectrum on average more intensively in a first wavelength region (K) than in a second wavelength region (L). The light filter is configured to let through light, which is emitted by the second LED, according to the transmission spectrum, on average less in the second wavelength region than in the first wavelength region.

A solid-state video camera is equipped with pixel addition logic such that, if the measured object brightness falls below a certain threshold value, a brightening of the image is effected without increasing the noise component accepting a loss in real-time representation. The pixel addition by way of the pixel addition logic is coupled to the gain control of the camera in a manner such that, in each case, the gain control compensates for jumps in brightness which arise by way of the pixel addition and creates for the user a flowing transition without noticeable jumps in brightness.

The invention relates to a method and apparatus for the automatic identification of components of medical apparatus systems, in particular, components of endoscopy systems. There is provided a unit which is separate from at least one of the components (30a, 30b) to be identified, this unit includes a write-read head. This unit may for example be one of the system components such as a camera head (18) in a video endoscope system. Each component to be identified includes a writable and readable data carrier which stores data signals indicating component parameters. Contents of the data carrier can be read in by transmission of the data to the write-read head from the separate unit and may here be registered and where appropriate, activate control and/or regulation procedures. According to the invention, the employed data transmission system is a touch-free system, with which the energy for reading out or registering the data into the data carrier of the components is transmitted by induction from the write-read head of the separate unit to the component. The separate component further contains a modulation-demodulation device with which the signals to be transmitted to the component are modulated and the data signals received by the component are demodulated. A video camera (15a) connected to the camera head (18) may, on account of the data read out by the components (30a, 30b), be automatically adapted to their specifications.

The invention relates to a device for connecting a fiber optic cable to the fiber optic connection of an endoscope. An end section of the optical fiber is mounted as a bundle of fibers in a housing part and a coupling part is provided for the fastening with a positive fit of this housing part to the fiber optic connection on the endoscope side. To ensure that the optical fiber ends always come into contact with one another free of play and to improve the cleaning access, the coupling part is arranged on the housing part axially displaceable against a spring force in the direction of the fiber optic connection on the endoscope side.
