In order to produce a sharply focused image, in particular a magnified image of an object, a process is proposed by which a structure is projected onto the object, the object is recorded in several planes (focal planes) perpendicular to the direction of observation, the contrast of the adjacent image areas is determined for each plane, the contrast between corresponding image areas of different planes are compared with each other, image areas of maximum contrast are selected from various planes and at least the latter is provided as a contract maximum image for further processing.
