ABSTRACT:
A device, method and a computer program product are shown for correcting the focus error in an optical device, wherein in a first position of the optical device at least one focus detector is focused onto a given image plane of the target subject and the distance (d1) between the optical device and the given image plane is locked and wherein in a second position of the optical device following a reorientation of the optical device for achieving the desired framing of the image the shutter is released, the method comprising sensing a distance vector parallel to the focus plane after reorientation between the first position and the second position after reorientation, calculating a focus correction value (de) from the sensed distance vector and adding the focus correction value (de) as a corrective to the locked focus distance (d1).
