Verfahren und Bilderfassungssystem zur achromatisierten Bildaufnahme von Objekten

DE 102007001010 A1 UPAB: 20080729 NOVELTY - The method involves correcting longitudinal color error to respective wavelength regions by focusing adapted to the wavelength regions. Chromatic transverse aberrations are corrected by an electronic and/or software-supported image post processing for the respective wavelength regions. The focusing is enabled by a lens (1) such as adaptive lens e.g. fluid lens, whose refraction power is changed. The wavelength regions are separated by application of wavelength filters with a polychromatic radiation source. USE - Method for image acquisition of an object by sequential recording of individual images for different wavelength region by a lens and an image sensor by an image acquisition system (claimed) i.e. camera system, in an electronic device such as mobile telephone and personal digital assistant (PDA). ADVANTAGE - The longitudinal color error to respective wavelength regions is corrected by focusing adapted to the wavelength regions, and the chromatic transverse aberrations are corrected by the electronic and/or software-supported image post processing for the respective wavelength regions, thus providing simplified lens installation, while enabling image acquisition without chromatic aberrations
