Abstract

A device includes a plurality of imaging optical channels inclined in relation to one another, each of which includes an optic and at least one detector pixel arrangement. The plurality of optical channels are configured to obtain an image of a dot pattern of a field of view by imaging said field of view. The optical channels pass through the display plane and are set up for imaging (projecting) the field of view between the display pixels. The device includes an evaluator that is coupled to detector pixels of the detector pixel arrangements and configured to evaluate the dot pattern on the basis of a comparison, which causes hyper resolution, of signal intensities of different detector pixels so as to obtain an evaluation result, and to control the device at least partly on the basis of the evaluation result.
