Abstract: In order to improve the noise suppression in a video image stream 3 of a medical image recording system, the video image stream including a sequence of frames, it is provided that an image processing unit 5 of the image recording system analyses the video image stream 3 continuously in real time and determines at least one variability between successive image pixels of the frames, for example of spatially adjacent image pixels of frames and/or of image pixels of a plurality of the frames corresponding to one another spatially and temporally, in order, on the basis of the variability determined, to set at least one parameter of a noise suppression subsequently applied to the video image stream 3. As a result, the noise suppression can be adapted continuously to a current recording situation.

Abstract: Method for commissioning a camera control unit (CCU) (1) which defines a first processing path for video data, wherein an operating program for the CCU (1) is loaded from a non-volatile program memory (2, 6) into a temporary memory (3) of the CCU (1), and a check is carried out to determine whether an expansion unit (5) is connected to the CCU (1), and, if so, at least a part of the operating program is loaded from a non-volatile program memory (6) of the expansion unit (5) into a temporary memory (3) of the CCU (1).

Abstract: A method for marking an image region in an image of an image sequence includes the steps of: identifying (S2) an image region (3) in a first image (1) of the image sequence, determining (S5) a transformation between the first image (1) and a second image (4) of the image sequence, transforming (S6) the image region (3) on the basis of the determined transformation, and presenting (S6) the transformed image region (3?) in the second image (4).
