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 (r.sub.o, g.sub.o, b.sub.o) of an output pixel (54) in the pseudocolor image (53) from at least one pseudocolor (r.sub.p, g.sub.p, b.sub.p), a color (r.sub.i, g.sub.i, b.sub.i) 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 (r.sub.o, g.sub.o, b.sub.o) 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.

A method of operating a video camera includes capturing a scene of imaging data using a focal plane array (FPA) module of the video camera. The scene of imaging data is characterized by a first bit depth. The method also includes processing, using an image processing module coupled to the FPA module, the scene of imaging data to provide display data characterized by a second bit depth less than the first bit depth. The method further includes forming a super frame including the display data and the scene of imaging data and outputting the super frame.
