Abstract

A multifocal representation device with a digital image generation module and a control unit, which conveys to the digital image generation module two-dimensional image data of a three-dimensional object to be represented, is provided, wherein the digital image generation module, based on the two-dimensional image data conveyed, generates two-dimensional images of the object from at least two different object planes in corresponding different focal planes in such a way that an observer can focus with his eye on the different focal planes in order to perceive the represented object three-dimensionally, and wherein the control unit determines for each two-dimensional image to be represented a sharpness value in sections and sets the image data to dark for the image sections the sharpness value of which lies outside a sharpness value range predetermined for the image.
