A method and apparatus for carrying out a multi - focal plane - image acquisition and - compression

摘要

There are exemplary method and apparatus for carrying out an image acquisition and - compression with a plurality of focal planes discloses. The disclosed exemplary device (100) includes a contrast detector (140) for calculating a contrast metric (145) for a first image (107) of an object (105) at a first focal plane and with a first resolution, an acquisition control (120) for comparing the contrast of the metrics (145) with a threshold value in order to determine whether a second image (107) of the object (105) at the first focal plane and with a second high resolution, the second resolution of the first resolution, an image acquisition a direction (110), the selectively operable about the first and the second image (107), and an image compression module (150) for storing a first display of the object (105) at the first focal plane in a file (155), wherein the file (155) a second display of the object (105) at a second focal plane, the said second representation of a different resolution than the first representation corresponds to.
