摘要： Examples relate to apparatuses, methods and computer programs for a microscope system, more specifically, but not exclusively, to the use of two optical imaging modules to obtain image data having a first and a second field of view. The apparatus comprises an interface. The interface is suitable for obtaining first image data of a sample from a first optical imaging module. The first image data has a first field of view. The interface is suitable for obtaining second image data of the sample from a second optical imaging module. The second image data has a second field of view. The first field of view comprises the second field of view. The apparatus comprises a processing module. The processing module is configured to generate an image output signal for a display of the microscope system. In some embodiments, the processing module is configured to process the first image data to detect an abnormality outside the second field of view. In this case, information on the abnormality is overlaid over the second image data within the image output signal. Additionally or alternatively, an overview of the first image data is overlaid over the second image data within the image output signal. The processing module is configured to provide the image output signal to the display.

摘要： Examples relate to an optical system and to a corresponding apparatus, method and computer program. The optical system comprises a display module for providing a visual overlay to be overlaid over an object in an augmented reality or mixed reality environment. The optical system comprises at least one sensor for sensing at least one optical property of the object. The optical system comprises a processing module configured to determine the at least one optical property of the object using the at least one sensor. The processing module is configured to determine a visual contrast between the visual overlay to be overlaid over the object and the object, as perceived within a field of view of the augmented reality or mixed reality environment, based on the at least one optical property of the object. The processing module is configured to selectively adjust an illumination of one of more portions of the field of view, or an optical attenuation of the one of more portions of the field of view, based on the determined visual contrast between the visual overlay to be overlaid over the object and the object.

摘要： The invention relates to a medical inspection apparatus (1), such as a microscope or endoscope, and to a medical inspection method such as microscopy or endoscopy. Visible image data (11) representing a visible-light image (49) and fluorescence image data (12) representing a fluorescent-light image (51) and a pseudocolor (70, 71) are merged to give an improved visual rendition of an object (2) which comprises at least one fluorophore (6) to mark special features of the object (2). This is accomplished in that an image processing unit (18) of the microscope (1) or endoscope is configured to compute a color (ro, go, bo) of an output pixel (54) in the pseudocolor image (53) from at least one pseudocolor (rp, gp, bp), a color (ri, gi, bi) of a first input pixel (50) in the visible-light image (49) and an intensity (f) of a second input pixel (52) in the fluorescent-light image (51). In particular, the color (ro, go, bo) may result from a linear interpolation in a color space (RGB) between the pseudocolor and the color of the first input pixel (50) of the visible-light image (49) depending on the intensity (f) of the second input pixel (52) in the fluorescent-light image.

摘要： The invention relates to a method, an image processor (26) and a medical observation device (1), such as a microscope or endoscope, for observing an object (4) containing a bolus of at least one fluorophore (12). The object (4) is preferably live tissue comprising several types (16, 18, 20) of tissue. According to the method, a set (34) of component signals (36) is provided. Each component signal (36) represents a fluorescence intensity development of the fluorophore (12) over time in a different type of tissue. A time series (8) of input frames (10) is accessed, one input frame (10) after the other. The input frames (10) represent electronically coded still images of the object (4) at subsequent time. Each input frame (10) contains at least one observation area (22) comprising at least one pixel (23). In the observation area (22) of the current input frame (10) of the time series (8), a fluorescent light intensity (I) is determined over at least one fluorescence emission wavelength (15) of the fluorophore (12). This fluorescent light intensity (I1) is joined with the fluorescence light intensities (In) of the observation area (22) of preceding input frames (10) of the time series (8) to generate a time sequence (40) of fluorescent light intensities (I1, In) of the observation area (22). This time sequence (40) is decomposed on in a preferably linear combination (72) of at least some of the component signals (36) of the set (34). A new set (34) of component signals (36) is provided which includes only those component signals (36) which are present in the combination (72). An output frame (46) is generated, in which the observation area (22) is assigned a color from a color space depending on the combination (72) of component signals (36).
