摘要： For simplified, less computationally intensive, image recording of different spectral signal components using a plurality of color channels of a single image sensor, a targeted adjustment of a sensitivity of at least one of the color channels in relation to another one of the color channels of the image sensor is provided for a spectral separation of this reduced or adjusted color channel from the other color channel so that at least one certain spectral range (i.e., in particular a part of a first spectral range captured using the other color channel) is no longer detectable using the color channel that has been adjusted in terms of its sensitivity. This adjusted color channel becomes spectrally blind in the spectral range and can consequently spectrally selectively detect a further spectral range (specifically a second spectral range deviating from the first spectral range). The second spectral range may include a fluorescence wavelength.

摘要： An endoscope (1) includes a first beam path (3) formed at least at a distal end (2), and an image recording chip (5), which captures the first beam path (3). The endoscope includes a shutter apparatus (7) having a shutter element (8) composed of a semiconductor material, which is formed in the first beam path (3). The shutter element (8) is arranged adjustably between a position that releases the first beam path (3) and a position that alters a transmission in the first beam path (3), in particular a position that switches off the first beam path (3).

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 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： A method for multispectral recording of an image stream, in which a sequence of single images of a scene, in particular a continuous video image data stream, is recorded as an image stream using an image sensor of an image recording system. At least two different types of single images are recorded in different associated wavelength ranges using the image sensor. At least one type A single image of the sequence is recorded during a chronological type A recording segment and at least one type B single image of the sequence is recorded during a chronological type B recording segment. The type A recording segment and the type B recording segment are chronologically separated from one another by a respective waiting interval, in which no image data are sensorially acquired using the image sensor. An image recording system is also provided that to carry out the method.
