Abstract
For detecting movements of a sample with respect to an objective, the sample is imaged onto an image sensor comprising an array of pixels by means of the objective. Images of the sample are recorded in that light coming from the sample is registered at the pixels. Variations of intensities of the light coming from the sample and registered at the pixels are determined during a set-up period in that a temporal course of the intensity of the light, which has been registered at a respective one of the pixels over the set-up period, is analyzed. Using these variations as a criterion, a subset of not more than 90% of the pixels of the image sensor is selected. Parts of the images that each correspond to the selected subset are compared to parts of at least one reference image that also correspond to the subset.
