摘要： For high-performance “advanced imaging” applications, a synchronization signal (13), which is output by a playback device (14) or another data sink, such as a server application, is used to synchronize the chronological recording of an image stream (1) chronologically exactly with the playback of this image stream on the playback device and/or to synchronize the recording with an alternating illumination. Here, the synchronization signal (13) is used to trigger an image recording frequency of an image sensor (7) of an image recording system (23), by which the image stream is recorded. Furthermore, the synchronization signal can also be used to chronologically trigger a light source (21) of the image recording system, so that during the recording of the sequence of single images (2), an alternating illumination is obtainable, which is also synchronized with the recording of the single images and/or the image playback on the playback device.

摘要： A method and a visualization system for displaying image data are provided, which, based on a set of different sequences, which are already predefined and stored in a memory, of visualization modes following one another in a specific order, always only provides a limited subselection of overall visualization modes usable using the visualization system for selection to a user, so that the user can change back and forth quickly and efficiently with the aid of an input between the visualization modes which are best suitable for the present application of the visualization system.

摘要： To improve the image quality and color authenticity of a white light image (5), which is sensorially acquired in the context of multispectral imaging, different sub-spectra (2) of a light spectrum (1) used for imaging are sensorially acquired either spatially separately or chronologically separately from one another and in the computation of the white light image (5), a secondary spectrum (4) of these sub-spectra (2) is taken into consideration which is acquired separately (chronologically or spatially) from a main spectrum (3) of the light spectrum (1). This approach offers the advantage that an additional spectral component (6), which is based on the separately acquired secondary spectrum (4), can thus be injected as needed into the white light image (5) or extracted therefrom, to thus achieve the desired improved image quality.

摘要： A device (1) and a method for transferring a raw image data stream (8) from an image sensor (6) via a data transfer connection (4) between a transmitter (2) and a receiver (3). In this case, the latency of the data transfer connection (4) is determined (S1), and the data rate of the raw image data stream (8) at the transmitter (2) is adapted (S3) to the determined latency.

摘要： So as to improve the quality of the transmission of a signal, in particular an image or video signal, from an image sensor (3) to a camera controller (5) of an endoscopy arrangement (1) by a cable (4) while maintaining electrical safety standards, a first circuitry arrangement that is used to transmit the signal within the cable (4) is embodied with galvanic isolation from a second circuitry arrangement (19) that is used to further process the signal within the camera controller (5). The galvanic isolation (6) is formed to this end, preferably downstream of a proximal end (7) of the cable (4) in the signal direction, and the first circuitry arrangement has an impedance matching circuit (8), preferably with a passive embodiment, for example arranged at the proximal end (7) of the cable (4) or in the camera controller (5). This impedance matching circuit is configured to compensate signal distortions, which arise during the transmission of the signal that is produced by the image sensor (3) to the camera controller (5), preferably in such a way that a frequency spectrum of the signal that is produced by the image sensor (3) can be reproduced.

摘要： An endoscope (1) is provided having a handle (2) and a probe part (3) that can be connected thereto, with an illumination system comprising at least one light emitting diode (6) and a video system having an image receiver being arranged in the handle (2). A carrier element (12) made of a heat-conducting material is provided for at least one light emitting diode (6) inside the handle (2), to which the light emitting diode (6) is directly connected. The carrier element thermally contacts the housing parts and/or installation parts of the handle (2) and the probe part (3) for heat conductivity and/or dissipation.

摘要： In summary, to simplify operation of a medical image acquisition system, it is proposed that the image acquisition system continuously monitors a current image acquisition situation and assigns at least one new function to at least one, preferably manual, operating element, which is adapted to a detected new image acquisition situation, in response to a change in the image acquisition situation, to the extent that said newly assigned function is adjustable and/or operable with the at least one operating element. To this end, the image acquisition system can detect the change in the image acquisition situation using predefined parameters by means of sensors and/or through communication with peripheral units and/or preferably through image analysis of an image sequence which is recorded with an image sensor of the image acquisition system.

摘要： An endoscope (1) with a shaft (2), a grip (3) connected to the shaft (2) at a proximal end region of the shaft (2), and a viewing region (4) formed in a distal end region of the shaft (2) by optical elements. The shaft (2) has at least one proximity sensor (5), of which the measuring region lies at least outside the viewing region (4), preferably in such a way that the measuring region of the proximity sensor (5) covers at least the distance of the lateral region of the distal end region. The endoscope has an evaluation device (6) which is configured to generate a warning signal when a definable distance threshold value is undershot.

摘要： An optical assembly (1, 100) is provided, including an optical functional unit (2), a housing (3), which at least partly encloses the optical functional unit (2), and an adjusting device (4), by which a desired position of the optical functional unit (2) relative to an optical axis (16) of the optical assembly (1, 100) is settable. The adjusting device (4) is configured to the effect that the position of the optical functional unit (2) is set by way of an operative connection (5) between an actuation part (9, 10) and a holding part (11, 12, 28, 29) of the adjusting device (4). The operative connection (5) is configured in the region of a closed housing wall (6), and wherein the optical functional unit (2), after the setting of the desired position, is fixable in this position.
