Claim One:
1. A method for processing a medical video image for reducing perceived noise, the method comprising: determining an area of interest in the medical video image, the area of interest being determined in dependence of a foveal vision of a user; and applying a stronger noise filtering in a peripheral area of the medical video image than in the area of interest, the peripheral area being outside the area of interest and corresponding to a peripheral vision of the user, wherein applying the stronger noise filtering comprises applying a noise reduction filter mask to the peripheral area of the medical video image around the area of interest that reduces high frequency temporal content and spatial information content of the peripheral area; wherein applying the stronger noise filtering further comprises applying a noise filtering algorithm in the image, wherein the algorithm comprises a temporal weighted averaging of individual pixels over consecutive frames of the image with weights determined by weight parameters that decrease as a distance from a center of the area of interest increases and threshold parameters that increase as the distance from the center of the area of interest increases.
