Abstract: The invention is directed to method for positioning and aligning a preferably biological sample in the detection area of the objective of a microscope arrangement. According to the invention, the method mentioned above has the following method steps: a sample is introduced into a transparent medium, preferably agarose gel, which is initially liquid; the medium is changed from the liquid state to the solid state, wherein the sample is fixated within the medium, but the transparency of the medium is retained; the solidified medium is positioned in the microscope arrangement in such a way that the sample enclosed therein is situated in the detection area of the objective. Further, a device is proposed for positioning and aligning a preferably biological sample in the detection area of the objective of a microscope arrangement.

Abstract: A method of improving a signal in an image sequence acquired with a digital color video camera creating a digital video signal (1) including a brightness signal component (3) and a color signal component (4) includes the steps (6, 7) of continuously evaluating the brightness signal component (3) to calculate maximum brightness values and minimum brightness values at least within a first predetermined image sector and at least for a partial sequence of images, continuously calculating offset values on the basis of at least two previously calculated minimum brightness values, continuously calculating gain values based on differences between at least to previously calculated maximum brightness values and the associated minimum brightness values, continuously modifying the brightness signal component (3) by subtracting the last calculated offset value therefrom and by then multiplying it with the last gain value, and continuously modifying the color signal component (4) by multiplying it with the last calculated
