Title: Automatic focussing on object for image processing of microscopic esp. cytological preparations - deriving focussing device control signals from image contents using dual-out-of-focus principle
Inventor: SCHLIPF WOLFGANG
IPC: G02B21/24
Filed: 1992-08-11
Abstract: The method involves the use of an electronic image acquisition camera which acquires images from an image generation system and passes them to an image processing system. A partial image is formed using an object which is focussed on in a control loop. Signals are prepared from the partial image and used to determine focus criteria from which a control parameter for a focus adjuster are derived. The signals are derived according to the "dual-out-of-focus" principle, whereby an image is acquired in three different focussing planes ling at defined distances from each other. ADVANTAGE  - Very accurate focussing on individual relevant objects can be achieved using information derived from image contents.
